A medical device management system and a medical device management program according to an embodiment of the present invention will be described with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a network configuration diagram showing medical devices connected to the medical device management system according to the first embodiment of the present invention.

  The medical device management system 1 includes a hospital information system (HIS) 3, a radiology information system (RIS) 4, and a medical image storage and communication system (PACS) via a network 2. 5. It is connected to medical systems such as the medical image processing device 6 and the image diagnostic device 7.

  RIS4 is a medical information system that creates and manages patient examination reservation information. The PACS 5 is a storage device that functions as a medical image server. The medical image processing apparatus 6 is often configured by a computer having a large-scale data processing capability such as a work station (WS). Examples of the diagnostic imaging apparatus 7 include an ultrasonic diagnostic apparatus, an X-ray CT (computed tomography) apparatus, a magnetic resonance imaging (MRI), a positron emission computed tomography (PET) apparatus, Examples thereof include a nuclear medicine diagnostic apparatus such as a single photon emission computed tomography (SPECT) apparatus, an X-ray diagnostic apparatus, and the like.

  Thereafter, as shown in FIG. 1, the image diagnostic apparatus 7 connected to the network 2 is a first MRI apparatus (MRI1) 8, a second MRI apparatus (MRI2) 9, a first X-ray CT apparatus ( An example will be described in which the CT1) 10 and the second X-ray CT apparatus (CT2) 11 are connected to the WS as the medical image processing apparatus 6.

  The network 2 may be an in-hospital network within a medical institution, or a wide area network such as the Internet or a dedicated network installed between medical institutions. FIG. 1 shows that a LAN (local area network) 12 installed in a medical institution is connected to the Internet 13 and performs data communication between an external terminal 14 and a mobile terminal 15 outside the medical institution and each medical system. An example is shown that is made possible.

  The medical device management system 1 can be constructed by reading a medical device management program into an arithmetic device of a computer including the input device 16 and the display device 17. However, a circuit may be used to construct the medical device management system 1. The medical device management system 1 includes an examination reservation information acquisition unit 18, a schedule information creation unit 19, and a system activation unit 20.

  The examination reservation information acquisition unit 18 has a function of acquiring examination reservation information of a patient from the RIS 4 via the network 2 and a function of giving the acquired examination reservation information of the patient to the schedule information creation unit 19. The inspection reservation information acquisition unit 18 may acquire the inspection reservation information from the RIS 4 by notifying the RIS 4 of a request for transmitting the inspection reservation information. In that case, a test request information transmission request can be transmitted from the test reservation information acquisition unit 18 to the RIS 4 by using information or time input from the input device 16 to the test reservation information acquisition unit 18 as a trigger. Conversely, the examination reservation information acquisition unit 18 may passively acquire examination reservation information from the RIS 4.

  The schedule information creation unit 19 has a function of creating schedule information for at least one medical system of a plurality of medical systems based on the examination reservation information acquired by the examination reservation information acquisition unit 18. The schedule information creating unit 19 has a function of creating schedule information for the entire medical system according to information input from the input device 16, a function of creating schedule information for each medical system by referring to the schedule information of the entire medical system, As a response to the inquiry of the schedule information from the medical system, it has a function of transmitting the examination reservation information of the medical system and the schedule information of the medical system to the corresponding medical system.

  Further, the schedule information creation unit 19 is configured to change the schedule information once created according to the information received via the network 2. Therefore, it is possible to change the schedule information remotely by giving information to the schedule information creating unit 19 using the external terminal 14 or the portable terminal 15 outside the medical institution. In addition, schedule information can be shared between medical systems inside and outside the medical institution, and schedule information can be viewed from outside the medical institution.

  FIG. 2 is a diagram showing an example of schedule information of the entire medical system created by the schedule information creating unit 19 of the medical device management system 1 shown in FIG.

  As shown in FIG. 2, the schedule information of the entire medical system can be managed as a schedule table. Specifically, the first MRI apparatus (MRI1) 8, the second MRI apparatus (MRI2) 9, the first X-ray CT apparatus (CT1) 10, the second X-ray CT apparatus (CT2) 11, and the medical use The power ON / OFF switching time for each medical system such as the image processing apparatus (WS) 6 can be scheduled in advance. In addition to the power ON / OFF operation, the schedule information reception time for each medical system, the time to check the remaining amount of liquid helium used in the superconducting magnet of the MRI device, the time to check the virus of the computer system, etc. The execution timing of various operations can be defined as schedule information.

  Furthermore, the power consumption for each medical system can be included in the schedule information as reference information for setting the operation timing for each medical system.

  Such schedule information of the entire medical system can be created by the schedule information creating unit 19 by inputting necessary information from the input device 16 to the medical device management system 1.

  FIG. 3 is a diagram showing an example of examination reservation information managed in the RIS 4 shown in FIG.

  FIG. 3 shows an example of examination reservation information for the first MRI apparatus 8 and the second MRI apparatus 9. As shown in FIG. 3, for example, a table in which the name of a patient who has reserved an examination with items of date / time and identification information of the MRI apparatus is recorded can be managed as examination reservation information in RIS4.

  FIG. 4 is a diagram showing a first example of schedule information of the entire medical system created by referring to examination reservation information in the schedule information creation unit 19 of the medical device management system 1 shown in FIG.

  As shown in FIG. 4, schedule information for the entire medical system can be created with reference to examination reservation information. FIG. 4 shows an example in which schedule information for the first MRI apparatus 8 and the second MRI apparatus 9 is created, but schedule information is similarly created for other image diagnostic apparatuses 7 such as an X-ray CT apparatus. Can do.

  If the power consumption of the first MRI apparatus 8 and the second MRI apparatus 9 is the same or similar, the use time of the other MRI apparatus can be shortened by preferentially using one MRI apparatus. . FIG. 4 shows an example in which schedule information is created so that the first MRI apparatus 8 is preferentially used.

  That is, when the examination reservation information as shown in FIG. 3 is acquired in the schedule information creation unit 19 from the RIS 4 through the examination reservation information acquisition unit 18, if there are examination reservations for two patients at the same time, While both one MRI apparatus 8 and the second MRI apparatus 9 are used, when there is an examination reservation for one patient at the same time, the first MRI apparatus 8 is automatically used in accordance with an algorithm. Schedule information can be created.

  Thus, when the use schedule of the 1st MRI apparatus 8 and the 2nd MRI apparatus 9 is determined, the time slot | zone which does not use the 2nd MRI apparatus 9 will arise. Therefore, a schedule is created so that the power of the second MRI apparatus 9 is turned on immediately before the first examination of the day is executed, and the power is turned off immediately after the last examination is executed. Can do. Further, when a non-use time zone occurs during the inspection, it is possible to switch to a standby mode with less power consumption than when the power is turned on.

  As a specific example of the standby mode, among the components of the diagnostic imaging apparatus 7, there is a mode in which the power of the system with relatively large power consumption and a sufficiently short startup time is turned off. For example, if the diagnostic imaging apparatus 7 is an MRI apparatus, a semiconductor switch circuit and a high voltage generation circuit used for a gradient magnetic field power supply, an output power control circuit and a high voltage generation circuit used for a radio frequency (RF) power supply The power consumption is extremely large compared to other components. Thus, a state in which some or all of the power supplies of these circuit systems are turned off can be set as a standby mode.

  On the other hand, in the first MRI apparatus 8 as well, it is possible to set the time at which the power is turned on, the time at which the power is turned off, the switching time to the standby mode, and the end time of the standby mode. That is, the schedule is automatically created so that the power of the first MRI apparatus 8 is switched to the ON state immediately before the first inspection of the day is performed, and the power is switched to the OFF state immediately after the last inspection is performed. be able to. Further, the schedule can be automatically created so that the time zone used during the examination is in the standby mode.

  Note that FIG. 4 illustrates schedule information for two MRI apparatuses, but schedule information can be similarly created for a plurality of image diagnostic apparatuses 7 of the same type. That is, it is possible to create a schedule so that a plurality of image diagnostic apparatuses 7 of the same type are preferentially used in descending order of priority. In addition to the ON / OFF switching of the power supply, the standby mode in which the power consumption amount of each image diagnostic apparatus 7 is made smaller than the power consumption amount at the time of inspection according to the examination period using each image diagnostic apparatus 7. Schedule information including switching to can be created.

  In addition, if there is a period that is not temporarily used such as a lunch break, the period until the use is resumed can be set to the standby mode. Further, the schedule information can be created as the timing when the transfer of the medical image data to the PACS 5 is completed without setting the timing for switching the power supply to the OFF state.

  Furthermore, it is possible to set a virus check, a helium remaining amount check, and the like of the system using the software in a period such as a night without inspection. The virus check and the helium remaining amount check can be automatically performed in the first MRI apparatus 8 and the second MRI apparatus 9 by using virus removal software and a liquid helium remaining amount monitoring system.

  For example, in the case of checking the remaining amount of helium, the remaining amount of liquid helium is automatically detected in the monitoring system of the remaining amount of helium. If the detected remaining amount of liquid helium is extremely reduced, a notification indicating an abnormality is automatically transmitted to the service center of the diagnostic imaging apparatus 7 via the network 2.

  Therefore, a schedule is created so that the power is automatically turned ON immediately before operations other than inspection such as virus check and helium remaining check, and the power is automatically turned OFF after completion of operations other than inspection. can do.

  The operation of the diagnostic imaging apparatus 7 other than the inspection includes DQA (Daily Quality Assurance) work in addition to the virus check and the helium remaining amount check. DQA is a technique for detecting an abnormality in the diagnostic imaging apparatus 7 by recording data collected by phantom scanning. DQA is usually performed before the start of a medical institution. Therefore, if a schedule for automatically executing a DQA scan by installing a phantom in the diagnostic imaging apparatus 7 on the previous night, image data with the phantom as the subject can be acquired before the start of work. Incidentally, when abnormal data is recorded in DQA, a report can be automatically transmitted to the service center via the network 2.

  FIG. 5 is a diagram showing a second example of schedule information of the entire medical system created by referring to the examination reservation information in the schedule information creation unit 19 of the medical device management system 1 shown in FIG.

  The schedule information can also be created based on each power consumption of a plurality of medical systems such as the image diagnosis apparatus 7. If schedule information is created based on the power consumption for each medical system, the power consumption of the entire medical system can be reduced. The power consumption for each medical system can be set in advance in the schedule information creation unit 19 as a part of the schedule information of the entire medical system as shown in FIG.

  For example, as shown in FIG. 5, the first MRI apparatus 8 can generate a 3T static magnetic field, and the second MRI apparatus 9 can generate a 1.5T static magnetic field. In the case of the apparatus, the power consumption of the second MRI apparatus 9 is smaller than the power consumption of the first MRI apparatus 8. Therefore, preferential use of the second MRI apparatus 9 leads to power saving.

  Therefore, schedule information is created so that the image diagnostic apparatus 7 with low power consumption is preferentially used instead of preferentially using the image diagnostic apparatus 7 determined in advance by the user as in the example shown in FIG. can do. In the example shown in FIG. 5, the MRI apparatus used preferentially is the second MRI apparatus 9. Therefore, the patient to be examined is preferentially assigned to the second MRI apparatus 9.

  In this way, schedule information for each medical system can be created based on schedule information for the entire medical system created in advance in addition to examination reservation information. Of course, instead of using the strength of the static magnetic field as an index indicating the power consumption, the priority order of the medical system to be used may be determined based on the power consumption value itself.

  However, when a specific function is provided in a specific medical system, it is possible to create a schedule so that an examination that requires the specific function is executed by the medical system having the specific function. For example, in the example shown in FIG. 5, when the dedicated application software for executing the non-contrast blood vessel imaging examination is installed only in the first MRI apparatus 8, the first MRI apparatus 8 must be used. A non-contrast test cannot be performed. On the other hand, contrast examination may not be possible for patients with kidney disease. In such a case, it is essential to perform the inspection with the first MRI apparatus 8.

  Therefore, schedule information can be automatically created so that imaging having a specific purpose is executed by a specific medical system. In the example shown in FIG. 5, one person is inspected from 16:00. Therefore, based on power consumption alone, it is desirable to use the 1.5T second MRI apparatus 9 for inspection. However, only the 3T first MRI apparatus 8 can perform the non-contrast examination. Therefore, the schedule information creation unit 19 creates schedule information so that the examination is executed by the first MRI apparatus 8.

  As described above, the schedule information creation unit 19 can automatically create schedule information on the condition of the characteristics of the image diagnostic apparatus 7 other than power consumption. Note that the imaging information such as whether the examination is a contrast examination or a non-contrast examination can be automatically determined by the schedule information creation unit 19 based on examination reservation information acquired from the RIS 4. In other words, the examination reservation information includes the imaging purpose such as the specific information of the imaging region and the disease information. Therefore, it is possible to determine whether or not a specific function such as non-contrast imaging is necessary for the examination based on the information such as the imaging part specific information and the imaging purpose included in the examination reservation information.

  As another example of device restriction based on imaging conditions, an MRI device with a head coil or an MRI device to which a head coil can be connected is always used for head inspection. There is a restriction that The same applies to dedicated coils specialized for other imaging regions.

  The schedule information creation unit 19 transmits the schedule information for each medical system created in this way together with the examination reservation information to the corresponding medical system via the network 2 as a response to the transmission request for the schedule information from each medical system. Configured as follows.

  In addition, the schedule information creation unit 19 is configured to output a request for changing examination reservation information based on the schedule information to the RIS 4. For this reason, it is possible to appropriately change the inspection reservation based on conditions such as power consumption. That is, the examination reservation information can be changed so that more examinations are performed using the image diagnostic apparatus 7 with relatively low power consumption. Further, the use of the standby mode of the diagnostic imaging apparatus 7 can be reflected in the examination reservation information.

  The system activation unit 20 has a function of transmitting an activation request to a corresponding medical system prior to transmission of schedule information from the schedule information creation unit 19. In other words, the system activation unit 20 is a component for activating the medical system from the medical device management system 1 side, not as a response to a schedule information transmission request from each medical system.

  On the other hand, a medical system such as the image diagnostic apparatus 7 is configured to request the schedule information creation unit 19 to transmit schedule information and operate according to the schedule information received from the schedule information creation unit 19. Each medical system is configured to start by switching the power supply to the ON state when receiving a start request from the system start unit 20 via the network 2.

  FIG. 6 is a functional block diagram of the diagnostic imaging apparatus 7 shown in FIG.

  The diagnostic imaging apparatus 7 includes an imaging unit 30, an image transmission unit 31, and a power supply control unit 32. The imaging unit 30 is a component for collecting medical image data. Therefore, if the diagnostic imaging apparatus 7 is an MRI apparatus, the imaging unit 30 includes a coil, a gradient magnetic field power source, and the like. On the other hand, if the diagnostic imaging apparatus 7 is an X-ray CT apparatus, the imaging unit 30 includes an X-ray tube, an X-ray detector, and the like.

  The image transmission unit 31 is a component for transmitting medical image data collected by the imaging unit 30 to the PACS 5 via the network 2.

  The power control unit 32 is a component for switching ON / OFF of the power of each system constituting the diagnostic imaging apparatus 7. In particular, the power supply control unit 32 is configured to automatically turn off the power of the diagnostic imaging apparatus 7 when the reception notification of the medical image data transmitted to the PACS 5 is acquired from the PACS 5 by the image transmission unit 31. ing.

  The operation of the power supply control unit 32 enables the operation of the diagnostic imaging apparatus 7 in accordance with the schedule information in which the timing at which the transfer of the medical image data to the PACS 5 is completed is the timing at which the power supply is switched to the OFF state. That is, it is possible to automatically turn off the power of the image diagnostic apparatus 7 using a reception notification of medical image data from the PACS 5 as a trigger. Also, it is possible to eliminate the user's work of waiting for the end of transfer of medical image data and switching the power of the image diagnostic apparatus 7 to the OFF state.

  In addition, the power control unit 32 makes a request for transmitting the schedule information to the medical device management system 1 via the network 2 and acquires the schedule information, and turns on the power in the main system or a specific system of the image diagnosis apparatus 7 according to the schedule information. Has a function to switch the / OFF state. That is, the power supply control unit 32 automatically switches on the power supply of the system specified at the time specified by the schedule information, while automatically turning on the power supply of the system specified at the time specified by the schedule information. Has the function of switching to the OFF state. Thereby, switching of the power supply of the diagnostic imaging apparatus 7 based on power consumption and switching to standby mode are possible.

  Further, the power supply control unit 32 is configured to start the diagnostic imaging apparatus 7 by switching the power supply to the ON state when a startup request is received from the system startup unit 20 of the medical device management system 1 via the network 2. The Therefore, a standby state for responding to information transmitted from the system activation unit 20 can be set in each medical system.

  Note that a medical system other than the image diagnostic apparatus 7 such as the medical image processing apparatus 6 can also include a power supply control unit 32 having the same function. And each medical system can be automatically operated according to schedule information. For example, it is possible to automatically start up and end the system by designating the start time and end time of the medical image processing apparatus 6.

  Next, the operation and action of the medical device management system 1 will be described.

  FIG. 7 is a sequence chart showing operations of the medical device management system 1 and each medical system shown in FIG.

  First, in step S1, the schedule information creation unit 19 of the medical device management system 1 creates schedule information for the entire medical system as shown in FIG. The schedule information of the entire medical system can be created by inputting necessary information from the input device 16 to the schedule information creation unit 19 based on rules in the medical institution. Further, the schedule information of the entire medical system can include information other than the operation schedule such as the power consumption of each medical system.

  Next, in step S2, patient examination reservation information as illustrated in FIG. 3 is transmitted from the RIS 4 to the medical device management system 1 via the network 2. Then, the examination reservation information acquisition unit 18 of the medical device management system 1 gives the acquired examination reservation information to the schedule information creation unit 19. Alternatively, the examination reservation information acquisition unit 18 may request the RIS4 to transmit the examination reservation information, and the examination reservation information acquisition unit 18 may acquire the examination reservation information from the RIS4 as a response to the transmission request.

  Next, in step S3, the schedule information creation unit 19 of the medical device management system 1 schedule information indicating specific operation contents in each medical system based on the examination reservation information of the patient and the schedule information of the entire medical system created in advance. Create For example, schedule information can be automatically created so that the power consumption of the entire medical system is minimized. In addition, schedule information can be created so that an examination that requires a specific function such as non-contrast imaging is performed by the diagnostic imaging apparatus 7 that can perform the examination. As a result, schedule information as shown in FIG. 4 or 5 is created.

  Next, in step S4, the schedule information creation unit 19 of the medical device management system 1 requests the RIS 4 to change the examination reservation information so that the created schedule information and the examination reservation information are consistent. That is, the part of the examination reservation information included in the schedule information as shown in FIG. 4 or FIG. 5 is transmitted from the schedule information creation unit 19 to the RIS 4 via the network 2 as the examination reservation information after the change.

  Next, in step S5, the RIS 4 updates the existing examination reservation information according to the examination reservation information change request transmitted from the schedule information creation unit 19. Specifically, the RIS 4 replaces the existing examination reservation information with the examination reservation information transmitted from the schedule information creation unit 19. Thereby, the examination reservation information managed in the RIS 4 can be corrected so that the power consumption of the entire medical system is reduced.

  On the other hand, in step S <b> 6, the power supply control unit 32 provided in each medical system including the image diagnostic apparatus 7 sends a schedule information transmission request to the medical device management system 1. In other words, a schedule information transmission request is transmitted from each medical system to the medical device management system 1 via the network 2.

  Next, in step S7, the schedule information creation unit 19 of the medical device management system 1 sends schedule information and examination reservation information indicating the operation contents for each medical system to the corresponding medical system as a response to the transmission request for the schedule information. Send.

  In step S8, the power control unit 32 of each medical system controls the power according to the schedule information. As a result, the medical system can be operated according to the schedule information.

  For example, when collection of medical image data is completed in the image diagnostic apparatus 7, the image transmission unit 31 of the image diagnostic apparatus 7 transfers the medical image data to the PACS 5 via the network 2 in step S 9. When the transfer of the medical image data to the PACS 5 is completed, a transfer completion notification of the medical image data is transmitted from the PACS 5 to the power control unit 32 of the image diagnostic apparatus 7 via the network 2 in step S10.

  Then, in step S11, the power control unit 32 of the diagnostic imaging apparatus 7 switches off the power of the diagnostic imaging apparatus 7. As a result, the power supply can be automatically shut down after transfer of the medical image data. In addition, the operation according to the schedule information can be automatically executed in each medical system. For this reason, the operation by the user can be reduced.

  FIG. 8 is a sequence chart showing the operations of the medical device management system 1 and each medical system shown in FIG. 1 in an emergency.

  When an urgent examination is required, a user can activate a desired medical system by changing schedule information remotely using the external terminal 14 or the portable terminal 15 outside the medical institution.

  First, in step S21, the user transmits correction information of examination reservation information to the RIS 4 from the external terminal 14 or the portable terminal 15 via the Internet 13 or a network 2 such as a dedicated network. That is, information such as the specific information of the diagnostic imaging apparatus 7 used for the examination and the patient name is transmitted to the RIS 4. Then, in step S22, the RIS 4 modifies the existing examination reservation information according to the examination reservation information modification information. Thereby, the specific information of the diagnostic imaging apparatus 7 used for urgent patient examination and examination is registered in examination reservation information.

  Subsequently, in step S23, the user notifies the medical device management system 1 from the external terminal 14 or the portable terminal 15 to the medical device management system 1 via the Internet 13 or a network 2 such as a dedicated network. Then, in step S24, the examination reservation information acquisition unit 18 of the medical device management system 1 makes a transmission request for examination reservation information to the RIS 4 via the network 2.

  Therefore, in step S25, the RIS 4 transmits the latest examination reservation information to the medical device management system 1 via the network 2. In step S26, the examination reservation information acquisition unit 18 of the medical device management system 1 acquires examination reservation information in which an urgent examination is registered. The acquired examination reservation information is given from the examination reservation information acquisition unit 18 to the schedule information creation unit 19.

  Next, in step S27, the schedule information creation unit 19 creates schedule information for each medical system based on examination reservation information including an urgent examination and schedule information for the entire medical system created in advance.

  On the other hand, in the diagnostic imaging apparatus 7, it is desirable to reduce the power consumed even if there is a possibility that an urgent examination is performed. Therefore, in a time zone such as nighttime when the diagnostic imaging apparatus 7 is not used for normal examination, when a power activation instruction is transmitted through the network 2 such as the LAN 12, the power supply is turned on by receiving the power activation instruction as a trigger. It can be in a state where it can be switched.

  In such a case, in step S <b> 28, the schedule information creation unit 19 sends a schedule information creation completion notification including an urgent examination to the system activation unit 20. Then, the system activation unit 20 transmits an activation request via the network 2 to the diagnostic imaging apparatus 7 used for the emergency examination. For this reason, in step S29, the power supply control unit 32 of the diagnostic imaging apparatus 7 used for the emergency examination activates the diagnostic imaging apparatus 7 using the reception of the activation request as a trigger.

  Next, in step S30, the power supply control unit 32 of the diagnostic imaging apparatus 7 used for the emergency examination automatically switches the power supply to the ON state according to the existing schedule information, and then automatically updates the medical device management system 1 to the latest. A schedule information transmission request is made via the network 2.

  Next, in step S <b> 31, as a response to the schedule information transmission request, the schedule information creation unit 19 sends the emergency examination schedule information and examination reservation information to the diagnostic imaging apparatus 7 used for the emergency examination via the network 2. Send.

  Next, in step S <b> 32, the image diagnostic apparatus 7 used for the emergency examination operates according to the latest schedule information and examination reservation information received from the medical device management system 1. Thereby, the diagnostic imaging apparatus 7 can be easily operated in correspondence with an emergency examination.

  That is, the medical device management system 1 as described above is a system that creates schedule information of a medical system based on examination reservation information acquired from the RIS 4. In the medical device management system 1, it is possible to create appropriate schedule information so that the power consumption of the entire plurality of medical systems can be reduced, particularly based on information unique to each medical system such as power consumption.

  Therefore, according to the medical device management system 1, it is possible to reduce power consumption by appropriately operating the power supplies of a plurality of medical systems including the image diagnostic apparatus 7. Further, in the diagnostic imaging apparatus 7, it is possible to further save power by appropriately scheduling a standby mode with low power consumption.
