Description

  The present invention relates to a chemical liquid filling and injection system including a chemical liquid filling device that fills a chemical liquid into a chemical liquid syringe and a chemical liquid injection device that injects a chemical liquid from a chemical liquid syringe filled with the chemical liquid to a subject.

Medical diagnostic imaging apparatuses include CT (Computed Tomography) scanner, MRI (Magnetic Resonance Imaging) apparatus, PET (Positron).
Emission Tomography) apparatus, Angio apparatus, MRA (MR Angio) apparatus, and the like. When these devices are used, it is necessary to inject a medical solution such as a contrast medium or physiological saline into the subject. Accordingly, various chemical solution injection devices that automatically inject chemical solutions have been proposed and put into practical use.

  The chemical liquid injector has an injection head to which a chemical syringe is detachably attached. The drug solution syringe is filled with the drug solution, and the drug solution in the drug solution syringe can be injected into the subject by pushing the piston of the drug solution syringe into the cylinder by the drive mechanism provided in the injection head.

  A chemical syringe is divided into a prefilled type in which a chemical solution is pre-filled and a post-filling type in which a desired chemical solution is filled in injection into a subject. In the post-filling type liquid medicine syringe, the liquid medicine is filled into the liquid medicine syringe exclusively by medical personnel at the medical site. However, manually filling the chemical syringe with the chemical solution has a large work load. Therefore, the chemical syringe is filled with the chemical solution using the chemical solution filling apparatus.

  As a conventional chemical solution filling apparatus, the one described in Patent Document 1 is known. When the inspection condition is input, the chemical filling device described in Patent Document 1 calculates the amount of the necessary chemical based on the input inspection condition, and moves the piston member according to the calculated amount of the chemical Let Thereby, the chemical solution is filled from the container into the chemical solution syringe.

  In Patent Document 2, chemical liquid data and syringe data are acquired by a chemical liquid filling apparatus, and the chemical liquid filling apparatus fills the chemical liquid from the chemical liquid container to the chemical liquid syringe based on these data and also supplies the chemical liquid data to the chemical liquid injection apparatus. And transmitting syringe data. The chemical liquid data includes data such as the type of chemical liquid, the use for MR or CT, and the expiration date. Syringe data includes data such as the type of medicinal solution that can be used, whether it is for MR or CT, capacity, material, and expiration date.

In Patent Document 2, the chemical liquid filling apparatus can determine the suitability of the combination of the chemical liquid and the syringe from the chemical liquid data and the syringe data, and the same determination can be made in the chemical liquid injection apparatus. And a chemical | medical solution injection | pouring apparatus inject | pours a chemical | medical solution from a chemical | medical solution syringe, when it judges that the combination of a chemical | medical solution and a syringe is appropriate based on the data received from the chemical | medical solution filling apparatus. As a result, it is possible to prevent an inappropriate chemical from being injected into the subject.

  The chemical solution filling device described in Patent Document 1 is independent of the chemical solution injection device, and transmission / reception of data between the two is not considered. When injecting a chemical solution into a subject, the chemical injection device sets injection conditions such as an injection amount of the chemical solution into the subject. The injection amount is obtained based on the inspection conditions, and corresponds to the filling amount of the chemical liquid filled in the chemical liquid syringe with the chemical liquid filling apparatus. However, the chemical injection device neither outputs the inspection conditions input to the chemical solution filling device nor the filling amount calculated by the chemical solution filling device to the outside as data. Therefore, the operator needs to input data similar to that input to the chemical solution filling apparatus to the chemical solution injection apparatus.

  On the other hand, in the invention described in Patent Document 2, since the data acquired by the chemical liquid filling device is transmitted to the chemical liquid injection device, the chemical liquid injection device uses the data transmitted from the chemical liquid filling device for injection control of the chemical liquid. Can do.

  However, in the invention described in Patent Document 2, nothing is checked as to what kind of liquid syringe is actually attached to the liquid injector. When the chemical syringe filled with the chemical solution by the chemical solution filling device is directly attached to the chemical solution injector, no particular problem occurs. However, for example, when another chemical syringe is attached to the chemical injector before the chemical syringe filled with the chemical with the chemical filler is attached to the chemical injector, the data transmitted from the chemical filler is actually It will be different from that of the chemical syringe attached to the.

  Even in such a case, the chemical solution injection device described in Patent Document 2 injects the chemical solution from another chemical solution syringe based on the data transmitted from the chemical solution filling device. As a result, the chemical solution is injected into the subject under incorrect injection conditions.

  In the present invention, when a chemical solution syringe filled with a chemical solution is attached to the chemical solution injection device and the chemical solution is injected, the data used for filling the chemical solution with the chemical solution filling device is attached to the chemical solution injection device. It aims at making it correspond to a chemical | medical solution syringe reliably.

In order to achieve the above object, a chemical solution filling / injecting system of the present invention is a chemical solution filling / injecting system in which an empty chemical solution syringe is filled with a chemical solution, and the chemical solution is injected into the subject from the chemical solution syringe filled with the chemical solution.

And the chemical solution filling device and the chemical solution injection device fill the chemical amount filling data obtained by the chemical solution filling device together with the unique identification number which is the product number and serial number of the chemical solution syringe filled with the chemical solution by the chemical solution filling device. The device is configured so that it can be transmitted from the device to the liquid injector, and the liquid injector is associated with the unique identification number received from the liquid filler and the unique identification number of the liquid syringe attached to the liquid injector. In addition, the injection condition of the chemical solution is determined using the filling amount data .

  In the chemical liquid filling and injecting system of the present invention, data including the filling amount obtained by the chemical liquid filling apparatus and the unique identification number of the chemical liquid syringe is transmitted and received between the chemical liquid filling apparatus and the chemical liquid injecting apparatus.

(First embodiment)
Referring to FIG. 1, there is shown a fluoroscopic image imaging system 1000 according to a first embodiment of the present invention, which includes a chemical liquid injection device 100, a chemical liquid filling device 200, and a CT device 300 that is an imaging device. ing.

  The chemical liquid filling device 200 fills the chemical liquid syringe 500 with the chemical liquid stored in the chemical liquid container 600. The chemical solution injection device 100 injects the chemical solution filled in the chemical solution syringe 500 from the chemical solution syringe 500 to the subject. The chemical solution filling apparatus 200 and the chemical solution injection apparatus 100 constitute a chemical solution filling and injection system. The CT apparatus 300 captures a fluoroscopic image of a subject into which a chemical solution has been injected, and includes an imaging unit 301 that performs imaging and an imaging control unit 302 that controls the operation of the imaging unit 301. The imaging control unit 302 and the chemical solution injection unit 100 are connected so that they can communicate with each other.

  Moreover, the chemical injection device 100 and the CT device 300 are connected to the hospital management server 400 so that they can communicate with each other. The hospital management server 400 manages medical chart information and has a medical record information database including information on subjects.

  The chemical syringe 500 includes a cylinder 501 and a piston 502 provided in the cylinder 501 so as to be able to advance and retract. The cylinder 501 has a conduit portion 501b at one end thereof, and the piston 502 is inserted into the cylinder 501 from the other end which is the end opposite to the one end of the cylinder 501. A cylinder flange 501 a is formed at the other end of the cylinder 501. Similarly, the piston 502 has a piston flange 502 a at the end opposite to the end inserted into the cylinder 501.

  The cylinder 501 is provided with an IC tag 503. The IC tag 503 is also called a wireless IC tag, a non-contact IC tag, a non-contact IC chip, a non-contact data carrier, or the like, and is a device that uses RF-ID (Radio Frequency-Identification) technology. In the present invention, the IC tag 503 indicates a medium having an integrated circuit with a memory that performs data communication using a wireless or other non-contact communication medium and records information such as a solid identification code in a recordable or rewritable manner.

  The IC tag 503 has data (syringe data) relating to the chemical syringe 500, such as a unique identification number such as manufacturer, product number, serial number, date of manufacture, expiration date (number of times), capacity, and piston stroke. It is recorded. The IC tag 503 may be attached to the outer peripheral surface of the cylinder 501 with a label, or may be bonded with an adhesive. Alternatively, the IC tag 503 can be embedded in the cylinder 501.

  Hereinafter, the chemical solution filling device 200 and the chemical solution injection device 100 will be described in detail.

  First, the chemical liquid filling apparatus 200 will be described with reference to FIG. 2 which is a block diagram of the chemical liquid filling apparatus 200 shown in FIGS.

  In the chemical solution filling apparatus 200, a chemical solution syringe 500 is detachably attached, and the chemical solution syringe 500 that is attached is filled with the chemical solution. The amount of the chemical solution that is filled in the chemical solution syringe 500 by the chemical solution filling device 200 is equal to the amount of the chemical solution that is injected into the subject by the chemical solution injection device 100 (see FIG. 1). Therefore, the filling amount of the liquid medicine into the liquid medicine syringe 500 varies depending on the examination condition of the subject by the fluoroscopic imaging system 1000.

  Thus, in order to fill the chemical syringe 500 with a necessary amount of the chemical liquid, the chemical liquid filling apparatus 200 is based on a filling control unit 210 that controls the entire operation of the chemical liquid filling apparatus 200 and a command from the filling control unit 210. A filling operation mechanism 220 for operating the chemical syringe 500, a reader / writer 230 which is one of interface units for transmitting / receiving data to / from an external device, an input unit 240, and a display unit 250. Have.

  The reader / writer 230 reads data written to the IC tag 503 and writes data to the IC tag 503 in a non-contact manner. Therefore, the reader / writer 230 is disposed at a position where the IC tag 503 provided in the chemical syringe 500 is within a communicable range in a state where the chemical syringe 500 is mounted on the chemical filling device 200.

  The input unit 240 can be configured with a key switch, a touch panel, or the like, and accepts data input operations by an operator. The input unit 240 receives data relating to the inspection conditions used to determine the filling amount of the chemical solution into the chemical solution syringe 500.

  Data relating to examination conditions is mainly divided into subject data, drug solution data, and imaging conditions. The subject data includes, for example, the weight, sex, height, age, and the like of the subject into which the chemical solution filled in the chemical solution syringe 500 is injected. Examples of chemical data include, for example, the type of chemical to be filled, manufacturer, product number, viscosity, iodine concentration when the chemical is a contrast medium, and whether or not to use physiological saline as another type of drug together Or the like. Examples of the imaging conditions include a subject's imaging site and imaging time.

  From the input unit 240, at least data necessary for calculating the filling amount is input. The liquid medicine filling device 200 may be configured so that syringe data is also input from the input unit 240 by the operator. In this case, since the chemical filling device 200 does not need to read data from the IC tag 503, the data transmitting / receiving unit may be a writer having a writing function.

  The filling control unit 210 includes a determination unit 211, a calculation unit 212, a filling control unit 213, and a database 214.

  The determination unit 211 determines whether or not the drug solution syringe 500 is appropriate to be filled from the syringe data read by the reader / writer 230 and the data related to the inspection condition input from the input unit 240. The suitability of the filling of the chemical liquid is, for example, whether or not the chemical syringe 500 has exceeded the expiration date (number of times), whether or not the medicine to be filled is a medicine suitable for this test, and the chemical syringe 500 and the medicine For example, whether the combination is appropriate. If it is determined as inappropriate as a result of the determination, the filling control unit 210 issues a warning by a buzzer (not shown), a warning lamp (not shown) or the like, and stops the subsequent operation. On the other hand, if determined to be appropriate, the determination unit 211 sends the syringe data read by the reader / writer 230 and the data input from the input unit 240 to the calculation unit 212 as they are.

  The arithmetic part 212 calculates the filling amount of the chemical liquid into the chemical syringe 500 based on the sent data. The filling amount of the chemical solution, that is, the injection amount of the chemical solution into the subject is optimal for taking a good image. Subject factors such as the subject's weight, height, sex, and age, chemical components, physical properties, etc. It depends on factors such as imaging factors such as imaging site and imaging time.

  For example, when the drug solution is a contrast medium, one important factor for obtaining a good image is the total amount of iodine injected. Contrast agents have different iodine concentrations depending on the type, and different types of contrast agents have different amounts of iodine contained in the same amount.

  Therefore, coefficient data for each imaging region, effective component data for each type of drug (for example, in the case of contrast medium, iodine-containing concentration data for each type of contrast medium), and drug information corresponding to physical information such as the body weight and height of the subject. Total injection amount data and the like are stored in the database 214.

  The calculation unit 212 calculates the filling amount of the chemical solution by referring to the database 214 and applying the data relating to the above-described inspection conditions to a calculation formula determined in advance in consideration of these various factors. Note that the calculation procedure of the filling amount of the chemical solution in the calculation unit 212 may be the same as the calculation procedure of the injection amount of the chemical solution in the conventional chemical injection device, so here, a specific calculation formula, calculation method, and the like are described. Omitted.

  Further, the calculation unit 212 adds the data input from the input unit 240 and the filling amount calculated by the calculation unit 212 to the IC tag 503 through the reader / writer 230. If these data have already been recorded at the time of the previous filling, these data are rewritten.

  The filling control unit 213 controls the filling operation mechanism 220 based on the filling amount calculated by the computing unit 212 so that the chemical solution 500 is filled with the calculated filling amount.

  As shown in FIG. 1, the filling operation mechanism 220 includes a cylinder holder 221 and a piston holder 222.

  The cylinder holder 221 is formed with an arc-shaped recess that receives the cylinder flange 501 a of the chemical syringe 500 on the side surface. The recess is formed in a stepped shape having a placement surface on which the cylinder flange 501a is placed. The cylinder 501 is held by the cylinder holder 221 by placing the cylinder flange 501a on the placement surface so that the conduit portion 501b faces upward.

  The piston holder 222 is disposed below the cylinder holder 221 so as to face the cylinder holder 221 and is provided so as to be movable in a direction away from the cylinder holder 221 (arrow A direction) and a direction approaching the cylinder holder 221 (arrow B direction). It has been. Similarly to the cylinder holder 221, the piston holder 222 is also formed with a concave portion for receiving the piston 502 on the side surface. The piston 502 is held in the recess in a state where the piston flange 502a is positioned on the lower side of the piston holder 222 (the side opposite to the side facing the cylinder holder 221).

  The piston 502 is pulled out from the cylinder 501 by moving the piston holder 222 in the arrow A direction while holding the cylinder flange 501a and the piston 502 as described above. On the other hand, the piston 502 is pushed into the cylinder 501 by moving the piston holder 222 in the arrow B direction.

  For the movement of the piston holder 502, any driving mechanism such as a ball screw mechanism can be used as long as the mechanism can linearly move the piston holder 502. When a ball screw mechanism is used as a drive mechanism for the piston holder 502, the ball screw shaft is arranged in parallel with the moving direction of the piston holder 502, and the piston holder 502 is fixed to a ball screw nut that is screwed to the ball screw shaft. Accordingly, the piston holder 502 can be moved in the axial direction of the ball screw shaft according to the rotation of the ball screw shaft. For example, a stepping motor can be used as a drive source for the ball screw shaft.

  The filling amount of the chemical liquid into the chemical syringe 500 is proportional to the movement amount of the piston 222 with respect to the cylinder 221 when the piston 222 is moved in the direction of pulling out the piston 222 from the cylinder 221. Therefore, the filling control unit 213 controls the filling operation mechanism so that the piston holder 222 moves by a movement amount corresponding to the filling amount calculated by the calculation unit 212. As a result, the chemical syringe 500 is filled with the amount of the chemical calculated by the calculation unit 212.

  The display unit 250 can display various data input by the input unit 240, the filling amount calculated by the calculation unit 212, the progress of the filling operation, and the like as numerical values and images. In this embodiment, as shown in FIG. 1, the chemical filling device 200 has a touch panel 241 which also serves as the input unit 240 and the display unit 250 shown in FIG.

  In the chemical solution filling device 200 described above, an example is shown in which the chemical solution syringe 500 is held in a vertical state so that the conduit portion 501b faces upward. Any direction such as an oblique direction may be used. Also, with respect to the operation of the chemical syringe 500, the example in which the cylinder holder 221 is fixed and the piston holder 222 is moved is shown, but the piston holder 222 may be fixed and the cylinder holder 221 may be moved. Alternatively, both the cylinder holder 221 and the piston holder 222 can be moved.

Furthermore, although the filling control unit 210 includes the determination unit 211, the determination unit 211 is not essential in the present invention. For example, stone I be judged by the operator himself about appropriateness of liquid syringe 500 and the drug solution, incorporate functions determine the constant portion 211 to the arithmetic unit 212, so as to determine the suitability during the processing in the arithmetic unit 212 Also good.

  Next, the chemical liquid injector 100 will be described with reference to FIGS. 3 and 4.

  For example, as shown in FIG. 3, the chemical injection device 100 includes an injection head 110 attached to an upper portion of a movable arm 112 connected to a stand 111, and an injection control unit 101 connected to the injection head 110 by a cable 102. Have The injection control unit 101 includes an operation panel 103 that is an input unit, a display unit 104, and a hand unit 107 connected by a cable 108, and controls the operation of the injection head 110.

  As shown in FIG. 4, the injection head 110 is formed with two recesses 114 for holding the cylinders 501 in the head main body 113 so that two chemical syringes 500 can be attached at a time. The head main body 113 is provided with two piston drive mechanisms 130 that are driven independently of each other, corresponding to the recesses 114. The piston drive mechanism 130 is configured to hold the piston flange of the piston 502 at its tip.

  When two chemical syringes 500 are mounted, for example, one of the chemical solutions filled in the chemical syringe 500 can be a contrast medium and the other can be physiological saline. The two chemical syringes 500 attached to the head main body 113 are connected by a connecting tube 530. An extension tube (not shown) having a distal end portion connected to a catheter (not shown) is connected to the connection tube 530. By injecting the piston 502 into the cylinder 501 by the piston drive mechanism 130 with the catheter inserted into the subject, it is possible to inject contrast medium, inject physiological saline, and simultaneously inject both.

  Further, in the head main body 113, a reader / writer 140 that performs non-contact reading of data written to the IC tag 503 provided in the chemical syringe 500 and writing of data to the IC tag 503 is provided for each chemical syringe 500. It is provided corresponding to the mounting position. The reader / writer 140 is one of interface units for transmitting / receiving data to / from an external device, specifically, the chemical solution filling device 200.

  The above-described chemical injection device 100 will be further described with reference to FIG. In FIG. 5, an interface for connecting the chemical injection device 100 to the CT device 300 and the hospital management server 400 (both see FIG. 1) so as to be communicable is omitted.

  The injection control unit 101 includes an injection control unit 121 and an injection profile storage unit 122. When the chemical solution syringe 500 is attached to the injection head 110 and the reader / writer 140 reads each data from the IC tag 503 (see FIG. 4), each read data is sent to the injection control unit 121.

  At this stage, the injection control unit 121 displays each data read by the reader / writer 140 on the display unit 104 as a numerical value or an image, and reads the injection profile from the injection profile storage unit 122. The data sent from the reader / writer 140 includes filling amount data written in the IC tag 503 by the chemical filling device 200 (see FIG. 1). In the chemical injection device 100, the filling amount data is handled as injection amount data.

The injection profile storage unit 122 stores at least one injection profile corresponding to the chemical solution. Examples of injection profiles include
(1) Profile with constant injection rate,
(2) a profile having a plurality of stages with different injection rates;
(3) a profile having a simultaneous injection phase of contrast agent and saline as at least one stage (including only one case);
(4) a profile having a stage where the infusion rate varies with time since the start of infusion as at least one stage (including only one), and (5) at least one stage (only one stage) A profile including a stage in which the injection pressure changes with respect to the elapsed time from the start of injection,
Etc. In any case, the rate of change of the injection rate is determined so that the injection of the chemical solution is completed in a predetermined time.

  As a preferable example of a profile having a step in which the injection rate changes with respect to the elapsed time from the start of injection as at least one step (including only one case), the contrast agent injection rate is changed from the start of injection to a certain time. Decreases linearly and thereafter keeps the injection rate constant or increases, decreasing the contrast agent injection rate in at least one stage (eg linearly), while increasing the saline injection rate simultaneously Profile to be used.

  Furthermore, the injection control unit 121 determines that a predetermined amount of the chemical solution is supplied for a predetermined time based on the data on the injection amount of the chemical solution obtained from the chemical solution syringe 500 and the injection profile read from the injection profile storage unit 122. The injection condition of the chemical solution is determined so as to be injected into the subject with the injection profile. The injection controller 121 controls the piston drive mechanism 130 so that the piston drive mechanism 130 operates in an operation sequence according to the determined injection condition.

  The operation panel 123 has an injection start button. When the operator operates the injection start button, the injection control unit 121 actually operates the piston drive mechanism 130. When a plurality of injection profiles are stored in the injection profile storage unit 122 for each chemical solution, the operation panel 103 further includes a profile selection button so that the operator can select one of these injection profiles. ing.

  Next, a procedure for capturing a fluoroscopic image by the above-described fluoroscopic image capturing system 1000 will be described.

  First, the operator prepares an empty chemical liquid syringe 500, that is, a chemical liquid syringe 500 that is not filled with a chemical liquid, and a chemical liquid container 600 that stores the chemical liquid that is filled in the chemical liquid syringe 500. The chemical liquid syringe 500 is in a state where the piston 502 is pushed most into the cylinder 501. It is assumed that the chemical solution injection device 100, the chemical solution filling device 200, the CT device 300, and the like constituting the fluoroscopic image system 1000 are already prepared.

  Next, the operator attaches the prepared empty chemical liquid syringe 500 to the chemical liquid filling apparatus 200 with the conduit portion 501b facing upward. After the chemical solution syringe 500 is attached, the operator connects the chemical solution container 600 and the chemical solution syringe 500 by the tube 610.

  Next, the operator inputs data necessary for determining the filling amount of the chemical solution into the chemical solution syringe 500 as described above from the touch panel 241 of the chemical solution filling apparatus 200. On the other hand, the chemical filling device 200 reads syringe data recorded on the IC tag 503 of the chemical syringe 500 attached.

  The chemical liquid filling apparatus 200 determines whether or not the chemical liquid syringe 500 is suitable for filling with the chemical liquid from the data input by the operator and the syringe data read from the IC tag 503. As a result, when it is determined to be appropriate, the chemical liquid filling apparatus 200 calculates the filling amount of the chemical liquid into the chemical liquid syringe 500 using the input data, and fills the chemical liquid syringe 500 with the chemical liquid according to the calculation result.

  Hereinafter, an example of the operation procedure of the chemical solution filling apparatus 200 by the operator until the chemical solution syringe 500 is filled with the chemical solution will be described in the case where the chemical solution is a contrast agent.

  When the chemical syringe 500 is attached to the chemical filling device 200 and the data of the IC tag 504 is read by the reader / writer 230, the type (for example, capacity and usage) of the chemical syringe 500 is displayed on the touch panel 241 as an initial screen. . At the same time, the touch panel 241 also displays a schematic image of the body segment to be injected with this chemical solution. The schematic image of the body section is an image schematically representing the human body divided into a plurality of sections such as “head”, “chest”, “abdomen”, and “leg”. The operator selects one body segment by touching one of these schematic images. When a body segment is selected, the selected body segment is visually distinguished from other body segments, such as by darkening or changing hue.

  When the operator selects a body segment, an imaging region corresponding to the selected body segment is further displayed on the touch panel 241. For example, when “chest” is selected as the body segment, the imaging region is “heart” and “lung”. The imaging part may be displayed in characters, or may be displayed together with an icon in which the characteristics of the imaging part are designed. The operator selects one imaging part by touching one of these imaging parts. When an imaging part is selected, only the selected imaging part remains on the screen.

  Next, an input image of the subject's weight is displayed on the touch panel 241. In the input image of the weight, for example, the standard weight is displayed on the touch panel 241 as a default, and the operator increases or decreases it with the “+” button and the “−” button, and finally touches the “confirm” button. You can enter your weight. Alternatively, the numeric keypad can be displayed on the touch panel 241 along with the weight display field, and the operator can input the weight by touching the numeric keypad.

  Next, the touch panel 241 displays a screen for setting information related to the chemical solution. For example, if the drug is a contrast agent, the iodine concentration of the contrast agent is determined by the manufacturer and product number of the contrast agent, so a list of iodine concentrations of contrast agents that can be filled with this chemical solution filling device is displayed as a button. Displayed on the touch panel 241. When the operator touches the button corresponding to the iodine concentration of the contrast medium to be filled, the iodine concentration is input. Alternatively, a list of manufacturer names and product numbers may be displayed, and the operator may select the manufacturer name and product number from the list. In that case, the chemical solution filling apparatus has a database relating to the iodine-containing concentration associated with the manufacturer name and product number of the contrast agent.

  At this stage, the input items are still displayed on the screen of the touch panel 241, and the operator can check the items input so far on the screen. When a confirmation button is displayed on the touch panel 241 and the operator touches the confirmation button, the chemical solution filling apparatus 200 determines whether or not the chemical solution is filled as described above. Calculate the filling amount.

  After the filling amount is calculated, the calculated filling amount and a start button are further displayed on the touch panel 241. The operator confirms the displayed filling amount and touches the start button. The filling operation mechanism 220 operates to fill the chemical syringe 500 with the chemical solution.

  During the filling of the chemical solution, it is preferable to display the filling state of the chemical solution on the touch panel 241 so that the operator can visually recognize that the chemical solution is being filled. As the display image at that time, for example, an image showing an animation of the state in which the chemical solution 500 is being filled into the chemical solution syringe 500, and a numerical value indicating the filling amount of the chemical solution corresponding to the operation of the filling operation mechanism 220 are increasing every moment. And a combination of these images.

  When the drug solution is physiological saline, detailed setting as described above is unnecessary, and the filling amount can be set manually. For this purpose, a manual operation button is displayed on the initial screen of the touch panel 241 in addition to the type of the chemical syringe 500 described above. When the operator touches the manual operation button, the mode shifts to the manual operation mode. In the manual operation mode, for example, a numerical value indicating the filling amount to be set is displayed together with the “+” button and the “−” button, and the operator touches these buttons as appropriate to increase or decrease the numerical value to set the filling amount. To be able to. Alternatively, the filling amount can be set by displaying a numeric keypad instead of the “+” button and the “−” button and directly inputting a numerical value from the numeric keypad button. After setting the filling amount, the operator touches the start button displayed on the touch panel 241, thereby starting the filling operation.

  In order to detect mixing of air into the chemical liquid syringe 500 during the filling of the chemical liquid, it is preferable to provide an air detection sensor (not shown) in the tube 610 connecting the chemical liquid container 600 and the chemical liquid syringe 500. As the air detection sensor, any type of sensor such as an optical type, an ultrasonic type, and a capacitance type may be used as long as it can detect whether or not air is present in the tube 610. Can do. In any of the methods, the characteristics change between when the air exists in the tube 610 and when it does not exist, for example, in the case of an optical system, changes in optical characteristics such as refractive index, reflectance, and transmittance, The presence / absence of air in the tube 610 is detected by detecting a change in resonance characteristics in the case of the sound wave type and a change in capacitance in the case of the capacitance type.

  After filling the chemical solution, the touch panel 241 displays a message indicating that the filling of the chemical solution is completed and a confirmation button. When the operator confirms completion of filling of the chemical liquid and touches the confirmation button, the chemical liquid filling apparatus 200 writes the input data and the calculated filling amount data into the IC tag 503 of the chemical syringe 500.

  When the writing of data is completed, the operator removes the chemical solution syringe 500 filled with the chemical solution from the chemical solution filling device 200 and attaches it to the injection head 110 of the chemical solution injection device 100. In addition, the operator connects the extension tube to the chemical syringe 500 via the connection tube 530 (directly when only one chemical syringe 500 is attached), and connects the catheter provided at the distal end of the extension tube. The subject is inserted.

  The operator then selects an infusion profile as needed. On the other hand, the injection head 110 reads data recorded on the IC tag 503 of the chemical syringe 500 attached. Based on the data read from the IC tag 503, the chemical solution injection device 100 sets the injection conditions of the chemical solution so that the chemical solution is injected according to a predetermined injection profile determined in advance or an injection profile selected by the operator. decide.

  When the injection condition of the chemical is determined, the operator operates the injection start button of the input unit 123. Thereby, the piston drive mechanism 130 is driven in an operation sequence according to the determined injection condition, and the chemical solution in the chemical solution syringe 500 is injected into the subject.

  After injection of the chemical solution, the injection control unit 121 writes data indicating that the injection of the chemical solution is completed to the IC tag 503 through the reader / writer 140. This is for managing the usage history of the chemical syringe 500. However, since the usage history of the chemical syringe 500 can be substituted by referring to the data written in the IC tag 503 by the chemical filling device 200, writing of data to the IC tag 503 by the chemical injection device 100 is omitted. You can also Further, the usage history of the chemical syringe 500 can be managed by the chemical solution filling apparatus 200 by configuring a database in the chemical solution filling apparatus 200.

  After injecting the chemical liquid into the subject, a signal is sent from the injection control unit 101 of the chemical liquid injection apparatus 100 to the imaging control unit 302 of the CT apparatus 300, and the imaging unit 301 is based on the control signal from the imaging control unit 302. Take an image. An image picked up by the CT apparatus 300 is sent to the hospital management server 400 directly or via the drug solution injector 100. The hospital management server 400 records the CT examination result in the database. On the other hand, the injection control unit 101 of the drug solution injection device 100 transmits to the hospital management server 400 the drug solution injection data selected from various data read from the reader / writer 140, the injection time of the drug solution, the injection speed, the injection pressure, and the like. Therefore, in the database of the hospital management server 400, the injection condition of the chemical solution is recorded together with the CT test result.

  Further, CT imaging condition data (such as radiation conditions, exposure conditions such as radiation irradiation timing) is transmitted from the CT apparatus 300 to the drug solution injection apparatus 100, and the drug solution injection apparatus 100 as data to be transmitted to the hospital management server 400, The above imaging condition data may be added. The CT imaging condition data may be transmitted directly from the CT apparatus 300 to the hospital management server 400.

  As described above, the chemical filling device 200 calculates the filling amount of the chemical liquid into the chemical syringe 500 using the data related to the inspection conditions, and the chemical liquid syringe 500 is filled with a necessary amount of the chemical liquid. Waste can be eliminated.

  Further, the amount of the chemical solution filled in the chemical solution syringe 500 is written in the IC tag 503 provided in the chemical solution syringe 500, and the chemical solution injection device 100 is configured to read out the data written in the IC tag 503. Therefore, there is no need to calculate the injection amount of the chemical solution in the chemical injection device 100, and therefore it is not necessary for the operator to input data necessary to calculate the injection amount into the chemical injection device 100. As described above, by using the data used to fill the chemical liquid syringe 500 with the chemical liquid injection by the chemical liquid injection apparatus 100, it is possible to greatly reduce the work load on the operator.

  Furthermore, data on the filling amount of the chemical solution into the chemical solution syringe 500 (in other words, data on the injection amount of the chemical solution to the subject) is written in the IC tag 503 provided in the chemical solution syringe 500. Therefore, the chemical injection device 100 can reliably determine the injection condition of the chemical solution based on the data about the chemical syringe 500 actually attached to the chemical injection device 100, and can inject the chemical solution under the injection condition. . As a result, the medicinal solution can be prevented from being injected into the subject under erroneous injection conditions.

  In this embodiment, all the data necessary for calculating the amount of the chemical liquid to be filled in the chemical liquid syringe 500 by the chemical liquid filling apparatus 200 is given from the data written in the IC tag 503 and the data input from the input unit 240. An example is shown. However, a part of these data is recorded in the database of the hospital management server 400, and the chemical solution filling device 200 can be read out so that the data recorded in the hospital management server 400 can be read out as necessary. And the hospital management server 400 may be connected to each other so as to be able to communicate with each other (shown by a one-dot chain line in FIG. 1).

  Thus, by preparing a part of data as a database in advance, the amount of data written to the IC tag 503 and the data input operation by the operator can be reduced.

  Data that can be prepared as a database is data that can be identified from the data when the data is known. In the case of syringe data, if the unique identification number (for example, the product number and serial number) of the chemical syringe 500 is known, other data can be specified from the unique identification number. Similarly, in the case of chemical liquid data, if the unique identification number (for example, product number and lot number) of the chemical liquid is known, other data can be specified from the unique identification number.

  A database in which data that can be specified from such a unique identification number is recorded may be included in the drug solution filling apparatus 200 or the drug solution injection apparatus 100 instead of the hospital management server 400. However, since the hospital management server 400 records not only the data relating to the subject but also the data relating to each equipment such as the chemical solution injection device 100, the chemical solution filling device 200, and the CT device 300, the data can be centrally managed. . Further, the use history of the medical solution syringe 500 can also be managed by the hospital management server 400.

  When the chemical solution filling apparatus 200 and the hospital management server 400 are communicably connected, the chemical solution filling apparatus 200 further includes an interface 260 in addition to the reader / writer 230 as a data transmission / reception unit, for example, as shown in FIG. It can be. The hospital management server 400 (see FIG. 1) is connected via an interface 260 so that data can be transmitted and received.

  The connection method between the hospital management server 400 and the drug solution filling apparatus 200 may be wired connection or wireless connection. In the case of wired connection, for example, a cable connector can be used as the interface 260. In the case of wireless connection, for example, a wireless data communication device can be used as the interface 260.

  In the example illustrated in FIG. 6, the calculation unit 212 has a function of a determination unit. Accordingly, the data read by the reader / writer 230 and the data input from the input unit 240 are sent to the calculation unit 212, where the suitability of the chemical solution filling is determined and the filling amount is calculated. The data sent to the calculation unit 212 includes at least one of the unique identification number of the syringe and the unique identification number of the drug solution. The calculation unit 212 calls the data corresponding to the transmitted unique identification number from the hospital management server 400 via the interface 260 and uses it for calculating the filling amount. Since other processes in the filling control unit 210 are the same as those in FIG. 2, the description thereof is omitted here.

  Further, in the present embodiment, the example in which the chemical liquid filling amount by the chemical liquid filling device 200 is obtained by calculation in the calculation unit 212 is shown, but the database 214 corresponds to each inspection condition input to the filling control unit 210. In the case of having various filling amount data, the calculation unit 212 can obtain the filling amount of the chemical solution only by referring to the database 214 instead of the calculation.

FIG. 7 is a diagram showing an overall configuration of a fluoroscopic imaging system according to the second embodiment of the present invention. 8 is a block diagram of the chemical liquid filling apparatus shown in FIG. 7, and FIG. 9 is a block diagram of the chemical liquid injection apparatus shown in FIG. 7 to 9, the same components as those in the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and detailed description thereof is omitted. Further, in FIG. 9, an interface for connecting the liquid injector 100 to the hospital management server 400 so as to be communicable is omitted.

  In 1st Embodiment, the case where the data carrier which has recorded the unique identification number of the chemical | medical solution syringe 500 was able to be added or rewritten was demonstrated. In the present embodiment, a barcode 504 is provided on the chemical syringe 500 as a data carrier. Syringe data is recorded in the bar code 504, and the recorded data cannot be changed.

  Along with the provision of the barcode 504 on the chemical syringe 500, the chemical filling device 200 has a reader 270 for reading data recorded on the barcode 504. Similarly, the chemical liquid injector 100 also has a reader 150 for reading data recorded on the barcode 504.

  Furthermore, the chemical solution filling device 200 and the chemical solution injection device 100 are connected so that data communication is possible. Therefore, each of the chemical liquid filling apparatus 200 and the chemical liquid injection apparatus 100 includes interfaces 280 and 160 as data transmission / reception units, and the chemical liquid filling apparatus 200 and the chemical liquid injection apparatus 100 are connected via these interfaces 280 and 160. Data is sent and received. The connection method between the chemical solution filling device 200 and the chemical solution injection device 100 may be wired connection or wireless connection. In the case of wired connection, for example, cable connectors can be used as the interfaces 280 and 160. In the case of wireless connection, for example, wireless data communication devices can be used as the interfaces 280 and 160.

  The chemical solution filling device 200 and the chemical solution injection device 100 will be described mainly focusing on differences from the first embodiment. In the following description, the same matters as in the first embodiment are omitted.

  In the chemical solution filling apparatus 200, the syringe data read by the reader 270 is sent to the calculation unit 212. Based on the syringe data sent from the reader 270 and the data inputted from the input unit 240, the calculation unit 212 determines the suitability of the chemical solution filling and calculates the filling amount. When the filling amount is calculated, the calculation unit 212 transmits the syringe data read by the reader 270, the data input from the input unit 240, and the calculated filling amount data to the chemical solution injection device 100 via the interface 280. .

  In the chemical solution injection device 100, the data transmitted from the chemical solution filling device 200 is received via the interface 160 and sent to the injection control unit 121.

  On the other hand, the chemical syringe 500 filled with the chemical liquid by the chemical liquid filling apparatus 200 is detached from the chemical liquid filling apparatus 200 and attached to the chemical liquid injection apparatus 100. When the chemical solution syringe 500 is attached to the chemical solution injection device 100, the reader 150 reads syringe data from a barcode 504 provided on the chemical solution syringe 500. The syringe data read by the reader 150 is sent to the injection control unit 121.

  The injection control unit 121 compares the syringe data sent from the reader 150 with the syringe data sent from the drug solution filling apparatus 200 via the interface 160. If the two syringe data are different as a result of the comparison, a warning that the chemical syringe 500 attached to the chemical injector 100 is different is issued as an alarm. If the two syringe data match, the injection condition of the chemical solution is determined as in the first embodiment, and the piston drive mechanism 130 is operated so that the piston drive mechanism 130 operates in the operation sequence according to the determined injection condition. To control.

  As described above, even when a data carrier that cannot be additionally written or rewritten is used, the drug solution syringe 500 is filled with the drug solution by connecting the drug solution filling device 200 and the drug solution injection device 100 so that they can communicate with each other. The data used for this can be used for the injection of the chemical solution by the chemical injection device 100. As a result, the work burden on the operator is greatly reduced.

  Moreover, since the chemical injection device 100 reads the syringe data of the chemical syringe 500 that is actually attached, the chemical solution can be injected under the injection conditions corresponding to the chemical syringe 500 that is actually attached. As a result, the medicinal solution can be prevented from being injected into the subject under erroneous injection conditions.

In the present embodiment, the bar code 504 is used as the data carrier, but a two-dimensional code can also be used as the data carrier. Also, if the unique identification number of the liquid syringe 500 operator was to enter, medicine liquid filling device 200 and liquid injector 100 may not have a leader 270,150. In that case, of course, a data carrier is also unnecessary, and instead of reading the unique identification number of the chemical liquid syringe 500 by the readers 270 and 150, the operator can input the input unit 240 of the chemical liquid filling apparatus 200 and the operation panel 103 of the chemical liquid injection apparatus 100. Enter the unique identification number.

  Further, in the present embodiment, similarly to the first embodiment, the drug solution filling device 200 and the hospital management server 400 (see FIG. 7) can be connected to each other so as to be able to communicate with each other (shown by a one-dot chain line in FIG. 7). ). In this case, as shown in FIG. 10, the chemical filling device 200 communicates with the hospital management server 400 in addition to the interface 280 for data communication with the chemical injection device 100 (see FIG. 7). Interface 260 for data communication.

  In each of the above-described embodiments, an example in which the chemical solution injection device 100 determines the injection condition of the chemical solution has been shown, but the chemical solution filling device 200 can also determine the injection condition.

  In this case, there are roughly two methods for obtaining data necessary for the chemical solution filling apparatus 200 to determine the injection conditions.

  The first method is a method for transmitting data necessary for determining the injection conditions from the chemical solution injection device 100 to the chemical solution filling device 200 via the hospital management server 400. This method can be applied to either a case where the data carrier provided in the chemical syringe 500 can be additionally written or rewritten like an IC tag, or a case where data cannot be added or rewritten like a barcode. .

  The second method is a method of transmitting data necessary for determining the injection condition from the chemical solution injection device 100 to the chemical solution filling device 200 via a data carrier provided in the chemical solution syringe 500. This method can be applied only when the data carrier provided in the drug solution syringe 500 can additionally write or rewrite data like an IC tag.

  When data necessary for determining the injection conditions is transmitted to the drug solution filling apparatus 200 via the hospital management server 400, first, a drug solution injection profile is set in the drug solution injection apparatus 100, and the set injection profile is set in the hospital. Sent to the management server 400. The hospital management server 400 holds the examination conditions including the sent infusion profile as part of the chart information. The chemical filling device 200 receives the data of the examination condition from the hospital management server 400, and determines the injection condition of the chemical solution by the chemical injection device 100 in addition to the filling amount of the chemical solution based on the received data. Next, the chemical liquid filling apparatus 200 fills the chemical liquid syringe 500 with the chemical liquid according to the determined filling amount.

  Here, if the data carrier can be additionally written or rewritten, the determined filling amount and injection condition are additionally written or rewritten to the data carrier provided in the attached chemical syringe 500. The subsequent procedure may be the same as that of the first embodiment described above, except that the injection profile is set by the chemical solution injection device 100. When the data carrier cannot be additionally written or rewritten, the determined filling amount and injection condition are transmitted from the drug solution filling apparatus 200 to the drug solution injection apparatus 100 via the hospital management server 400. The subsequent procedure may be the same as that of the second embodiment described above, except that the injection profile is set by the chemical solution injection device 100.

  On the other hand, when data necessary for determining the injection conditions is transmitted via the data carrier, first, the chemical syringe 500 is attached to the chemical injection device 100. In this state, a chemical injection profile is set in the chemical injection device 100, and the set injection profile is written to the data carrier of the chemical syringe 500. Next, the chemical solution syringe 500 is attached to the chemical solution filling apparatus 200. Subsequent procedures may be the same as those in the first embodiment described above, except that after the chemical solution syringe 500 is filled with the chemical solution, an injection profile is set by the chemical solution injection device 100.

  In some cases, the chemical solution injection device 100 has a plurality of types of injection profiles, and it is desired to change the injection profile used when the injection conditions are determined by the chemical solution filling device 200. When the injection profile is changed, the injection condition of the chemical solution may also change. Therefore, in this case, before injecting the chemical liquid, the injection profile is set again in the chemical liquid injection apparatus 100, and the chemical liquid injection apparatus 100 performs data carrier or hospital management provided in the chemical liquid syringe 500 according to the reset injection profile. The injection condition transmitted from the server 400 can be changed.

  Further, in each of the above-described embodiments, the X-ray CT apparatus has been described as an example of the imaging apparatus. However, the present invention is similarly applied to an MRI apparatus, a PET apparatus, an ultrasonic diagnostic apparatus, a CT angio apparatus, an MRA apparatus, and the like. can do. Also in these imaging apparatuses, a contrast medium, physiological saline, or the like suitable for each can be used as the chemical solution.

Furthermore, conventionally, as a hospital management system, a medical information system “HIS” (Hospital Information System) for receiving and accounting for outpatients, and a radiation medical care information system “RIS” (Radiology) in the radiation department
Information System) is known. In general, HIS is a paper processing system for server management of image data, reception work, medical expenses, etc., and RIS is a system for radiation examination and medical care. In the present invention, the hospital management server is preferably a part of any of these HISs, RISs, and in-hospital information systems that link these.
