Description

Intelligent automatic injector capable of exhausting air accurately

Technical Field

The application relates to the field of medical appliances, in particular to an intelligent automatic injector capable of accurately exhausting air for a pre-filled injection syringe.

Background

To meet the need for periodic or long-term self-injection of drugs during home treatment of chronic diseases, pre-filled syringe cartridges suitable for self-injection have been developed. To accomplish self-injection, one way is to manually press the push rod of the prefilled syringe to perform injection, and the other way is to use an automatic injector to drive the push rod to perform injection. Compared with the prior art, the automatic injection mode is safer, more labor-saving and more efficient, and therefore, more and more attention is paid.

Even with automatic injectors, venting is required prior to insertion of the needle of the prefilled syringe into the patient. The common exhaust mode of automatic injector is a little according to mode and pressure sensor discernment mode, and wherein the some mode needs the user to click many times, and complex operation just can't accurate exhaust, and the sensitivity of pressure sensor discernment mode often is insufficient, can not respond to the pressure variation of gas and liquid fast, causes the liquid medicine extravagant easily. Especially, when filling the prefilled syringe of different specifications, the volume change, the viscosity change of receiving different medicines and the distance difference between push rod position and the actuating mechanism are equispaced, further lead to unable accurate exhaust, or exhaust excessively and waste medicine, or exhaust inadequately and lead to the air to get into the patient and not accord with injection specification.

In addition, if the direction of the prefilled syringe is different at the time of air discharge, the liquid medicine discharged from the prefilled syringe is also different. For example, a pre-filled syringe that is near vertical is more conducive to venting and reduces waste of medical fluid than a pre-filled syringe that is near horizontal. However, because of the lack of experience of the user, the direction of the pre-filled syringe may not be noticed during the venting operation, and thus the venting effect may be uneven.

Accordingly, improvements to existing auto-injectors are needed.

Detailed Description

Preferred embodiments of the present application are described in detail below with reference to examples. Those skilled in the art will appreciate that these exemplary embodiments are not meant to be limiting in any way. Furthermore, features in embodiments of the application may be combined with each other without conflict. In the different drawings, the same components are denoted by the same reference numerals. Other components and steps are omitted from the figures for brevity, but this does not indicate that the precisely-exhaustible intelligent auto-injector of the present application may not include other components. It should be understood that the drawings are not to scale and that the size, relationship, number of parts in the drawings are not intended as limitations of the application.

The overall structure of a smart auto-injector capable of precisely exhausting according to an exemplary embodiment of the present application is briefly described with reference to fig. 1 and 2.

As shown in fig. 1 and 2, the smart auto-injector 500 of the present application includes a host 200, the host 200 including a housing 210. The housing 210 forms an interior cavity (not labeled) configured to removably receive the syringe cartridge structure 100 (see fig. 3 a-4 b) filled with the pre-filled syringe 70. Thus, the intelligent auto-injector 500 of the present application employs a split design, i.e., the host 200 and the syringe cartridge structure 100 are separate components that need to be assembled together only at the time of injection. Therefore, the automatic injector can be reused, thereby saving materials and reducing the cost of users. In addition, because one host machine can be matched with different types of syringe bin structures, and each syringe bin structure can accommodate different types of pre-filled and sealed injection syringes with different dosages, the applicability of the automatic injector is improved. With respect to the specific configuration of the syringe cartridge structure 100, further details will be described later with reference to fig. 3a to 4 b.

As shown in the block diagram of fig. 2, the intelligent auto-injector 500 further comprises a driving means 260, an identification means 250 and a control means 240, wherein the driving means 260 is configured to push the piston 72 of the pre-filled syringe 70 (see fig. 4a and 4 b), the identification means 250 is configured to be able to identify the identification information of the pre-filled syringe 70, and the control means 240 is configured to receive the identification information from the identification means 250 and to issue an exhaust instruction and an injection instruction to the driving means 260 to perform an exhaust operation and an injection operation based on the identification information.

Thus, in the intelligent auto-injector 500 of the present application, the control device 240 can identify drug information, such as drug name and drug dosage, within the different pre-filled syringes 70 by processing the identification information. The smart auto-injector 500 may further include a storage 270 storing exhaust information (e.g., exhaust volume) corresponding to the drug information, and the control 240 may be configured to search the storage 270 for the corresponding exhaust information according to the identified drug information, and to intelligently adjust the driving signal provided to the driving 240 according to the exhaust information, so that various parameters for the exhaust may be adjusted, thereby achieving intelligent adjustment and accurate exhaust. Specifically, since the medicine information of the pre-filled injection syringe 70 has been identified, the venting information can be found in the storage device 270, and thus the control device 240 can issue an accurate driving signal so that the driving device 260 can precisely vent the air in a predetermined volume. In addition, the storage device 270 may also store injection information (e.g., injection speed) corresponding to the medicine information of the pre-filled syringe 70, so the control device 240 may also issue an injection command to the driving device 260 according to the injection information to perform a precise injection operation.

In addition, the control device 240 processes the identification information, and may also determine angle information of the pre-filled syringe 70, including at least a direction of the pre-filled syringe 70 and an angle of the pre-filled syringe 70 with respect to a vertical direction. Accordingly, the control device 240 can determine whether the pre-filled syringe 70 is needle-up and within a predetermined angular range relative to vertical. If the smart auto-injector 500 is not flipped within the predetermined angular range (i.e., the pre-filled syringe 70 is not flipped within the predetermined angular range), the control 240 prohibits the purging operation from being performed. As shown in fig. 7a, when an injection is performed, the smart auto-injector 500 is generally placed head down, and at this time, even if the user presses the degassing key 213, a degassing operation cannot be performed. The exhaust operation is allowed to be performed only after being flipped within a predetermined angular range. As shown in fig. 7b, the exhaust operation may be allowed to be performed only when the angle θ between the central axis X' of the smart auto-injector 500 and the vertical direction X is within a predetermined angle range. It is within such a predetermined angular range that the operation is performed so that the optimum exhausting operation can be completed according to the set driving stroke (for example, can be set at the time of shipment according to the dose), thereby not only ensuring sufficient exhausting but also avoiding waste of the liquid medicine. The predetermined angle range may be any one of 0 to 10 degrees, 0 to 20 degrees, 0 to 30 degrees, 0 to 45 degrees. Preferably, the predetermined angle range is 0 to 20 degrees, more preferably, the predetermined angle range is 0 to 10 degrees.

Specifically, as shown in fig. 5, the identification device 250 may include a read coil 251 configured to be able to read a radio frequency identification tag (hereinafter referred to as an RFID tag) 46 (see fig. 3 c) on the syringe cartridge structure 100 and transmit the read drug information to the control device 240. The read coil 251 may be disposed at an end of the main support 220 within the housing 200. When the syringe cartridge structure 100 is loaded into the housing 210 of the host 200, the RFID tag 46 on the syringe cartridge structure 100 is proximate the read coil 251 and, therefore, may be read by the read coil 251. The RFID tag 46 stores therein drug information of the prefilled syringe 70. Thus, the host computer 200 can recognize the medicine information of the pre-filled injection syringe 70 filled in the syringe cartridge structure 100, and further adjust injection parameters (e.g., the volume of the air discharge, the injection speed, etc.) according to the medicine information, thereby realizing intelligent air discharge and injection. Since the rfid tag 46 is provided on the end face of the cartridge structure 100, parallel placed read coils 251 may be provided on the host computer 200, thereby simplifying the design of the identification device. Through accurate discernment medicine, can judge exhaust gas volume and injection rate voluntarily, to different grade type, the accurate exhaust of medicine homoenergetic of different volumes and accurate injection.

In addition, the identification device 250 may further include a gyroscope 252 configured to sense angle information of the pre-filled syringe 70, and the control device 240 is configured to read the angle information recorded in the gyroscope 252 (e.g., after the vent key 213 on the housing 210 is pressed), and allow the control device 240 to perform the venting operation only when the angle information indicates that the needle 74 of the pre-filled syringe 70 is facing upward and has an angle with respect to the vertical of no more than a predetermined angle. Therefore, by controlling the upward angle of the needle 74 of the prefilled syringe 70, a further accurate air discharge operation can be realized, and the waste of the liquid medicine due to the improper operation angle can be effectively avoided. The predetermined angle may be any one of 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, and 45 degrees. Preferably, the predetermined angle is 20 degrees, more preferably, the predetermined angle is 10 degrees.

To provide intelligent guidance to the user, the intelligent auto-injector 500 may further include a reminder device 280 configured to receive instructions from the control device 240, and to issue reminder information, such as audio information, video information, haptic information, and/or text information. For example, through voice and light prompts, the exhaust operation, the injection operation and the abnormal information can be prompted, so that timely, accurate and friendly exhaust and injection guidance can be provided for patients.

For example, when the identified angle information of the pre-filled syringe 70 does not indicate that the needle 74 of the pre-filled syringe 70 is facing upward and the angle with respect to the vertical is not greater than a predetermined angle, the control device 240 prohibits the air discharge operation from being performed and issues an instruction to the reminder device 280 to cause the reminder device 280 to issue reminder information reminding the user to adjust the orientation and the angle with respect to the vertical of the intelligent automatic injector 500. Preferably, the control device 240 reads the angle information in the gyro 252 at intervals of less than 100 milliseconds, and timely determines the direction and angle of the smart auto-injector 500.

It should be noted that the above-exemplified reading coil and gyroscope are only examples given for illustrating how the medicine information and the angle information of the pre-filled syringe 70 are identified, but the present application is not limited thereto. For example, the host computer of the intelligent automatic injector of the present application may employ an optical recognition device to read medicine information (e.g., color chart or color scale) on the cartridge structure, and may employ, for example, hall-type, capacitive-type, or piezoelectric-type angular velocity sensors, etc., in addition to gyroscopes to recognize the angle information.

In addition, the circuitry of the control device 240, the storage device 270, and the identification device 250 may be integrated on a single printed circuit board 230, wherein the gyroscope 252 may be mounted on the printed circuit board 230 to provide a compact overall structure, as shown in FIG. 6. It should be understood that the circuitry of the control device 240, the storage device 270, and the identification device 250 may be provided on separate printed circuit boards, or the gyroscope 252 may be mounted on the stand 220, and the present application is not limited to any particular arrangement.

In addition, fig. 1 also shows a switch key 214 of the housing 210 and a panel 215. When the switch key 214 is pressed, the host 200 starts the power-on self-test operation. The panel 215 is a main component of the presentation device 280, and may be a display panel, for example, a liquid crystal display panel, for displaying various video information, text information, and the like. However, the present application is not limited thereto, and additional alert components, such as an audio component and a vibration component, may be included to provide audible and tactile cues to provide better intelligent guidance to the user.

In fig. 5, only the main push rod 261 is shown to schematically represent the driving device 260, and the driving device 260 may include a motor (not shown), for example, a brushed dc motor. The motor may drive the main drive ram 261 forward, thereby pushing the piston 72 of the pre-filled syringe 70 to complete the venting and injection operations. By setting the advance accuracy of the motor (for example, controlling the minimum distance by which the main body push rod 261 advances to 0.1 mm), the exhaust and injection accuracy can be further controlled.

Thus, by providing the identification means 250, the control means 240 and the driving means 260, it is possible to intelligently adjust for different medicines according to the identification information, and to precisely control the degassing and injection operations.

The syringe cartridge structure 100 that may be mounted on the host 200 of the intelligent auto-injector 500 is described below with reference to fig. 3 a-4 b.

As shown in fig. 4 a-4 b, a prefilled syringe 70 loaded within a syringe cartridge structure 100 may include a barrel 71 for containing a medical fluid, a piston 72 (e.g., a silicone plug) for pushing the medical fluid, a needle 74 for penetrating a patient, and a protective cap 75 (e.g., a silicone cap) for protecting the needle 74. It should be noted that in the exemplary syringe cartridge structure 100 of the present application, the prefilled syringe without the push rod is filled to further reduce the overall volume, and is convenient to carry and store, but the present application is not limited thereto, and the prefilled syringe with the push rod may be filled according to the host computer. For example, if the drive 260 of the host 200 does not have a host ram 261, a pre-filled syringe having a ram may be used. Since the pre-filled syringe 70 is an existing product, it will not be described in further detail herein.

As shown in fig. 3a to 4b, the cartridge structure 100 of the present application may include a cartridge body 10, a protecting cover 20, and a sheath 30. The cartridge body 10 is the main component of the syringe cartridge structure 100, can be formed as a hollow housing, and has a symmetrical design along its longitudinal axis, so that the front and back sides can be not distinguished when coupled with the host 200. The cartridge 10 is provided with a cartridge catch 11 for detachably engaging with a catch groove on the housing 210 of the main body 200 of the intelligent auto-injector 500 to secure the syringe cartridge structure 100.

The protective cover 20 may include an end plate 24, a side wall 25, and a protective tube 23, with a cavity defined between the side wall 25 and the protective tube 23 for receiving a first end of the sheath 30, the protective tube 23 defining a cavity for receiving a protective cap 75, and the protective tube 23 may be fixedly coupled (as shown in fig. 4a and 4 b) or rotatably coupled (not shown) with the end plate 24. The cover 20 has first and second ends opposite each other. As shown in fig. 3b, the first end of the housing 10 is provided with an inclined housing end face 13 and the second end of the protecting cover 20 is provided with an inclined protecting cover end face 21, the housing end face 13 and the protecting cover end face 21 being in contact with each other such that the protecting cover end face 21 moves along the housing end face 13 to move the protecting cover 20 away from the housing 10 when the protecting cover 20 rotates relative to the housing 10. As shown in fig. 3b, when the cover 20 is rotated relative to the cartridge body 10, the cover end surface 21 slides over the cartridge body end surface 13 such that the cover 20 is moved away from the cartridge body 10. To remove the cap 75, the second end of the cover 20 has a tail catch 22, for example, provided at the second end of the tube 23, as shown in fig. 4 a. The tail clasp 22 is configured to be able to clasp the protective cap 75 of the pre-filled syringe 70.

In the example where the shield 23 is rotatably coupled to the end plate 24, the tail clasp 22 causes the shield 75 to disengage linearly from the pre-filled syringe 70 as the shield 20 rotates relative to the cartridge 10 away from the cartridge 10. Typically, in the pre-filled syringe 70, the cap 75 is tightly snapped onto the end of the barrel 71, so there is a large friction between the cap 75 and the end of the barrel 71. When the protective cover 20 rotates relative to the cartridge body 10, the protective tube 23 may remain non-rotating, subject to the greater friction between the protective cap 75 and the end of the barrel 71, such that the protective cap 75 may remain non-rotating until the protective cap 75 is pulled a sufficient distance from the end of the barrel 71. When the cap 75 is pulled straight far enough away, the tail clasp 22 has essentially pulled the cap 75 out. Even when the cap 75 has not been completely pulled out at this time, the frictional force between the cap 75 and the end of the cylinder 71 is already small enough to break the cap 75 to generate chips.

In the example where the protective tube 23 is fixedly coupled to or integral with the end plate 24, the protective cover 20 may also be pulled out in a straight-pull manner by means of the sheath 30 described below.

The shield 30 is disposed within the cartridge body 10 so as to be linearly movable within the cartridge body 10 but not rotatable relative thereto such that a first end of the shield 30 extends beyond the end of the needle 74 of the pre-filled syringe 70 upon removal of the protective cover 20. For example, a spring force may be provided at the second end of the sheath 30 by an inner or outer member so that the sheath 30 may conceal the needle 74 after removal of the protective cover 20, but is able to retract when depressed to allow injection.

To further facilitate removal of the cap 75, the inner wall of the sheath 30 may be provided with a cap catch 32, as shown in fig. 4b, the cap catch 32 being configured to catch the cap 75 such that the cap catch 32 moves the cap 75 when the sheath 30 is advanced under elastic force, whereby the cap catch 32 and the tail catch 22 together complete the cap removal action. Therefore, with the aid of the helmet buckle 32, even with the direct pulling method, no effort is required. Moreover, after removing the protective cover 20 and the protective cap 75, the needle 74 is hidden by the shield 30, and the needle 74 is not visible to the patient, so that the mind of the patient about needle may be relieved.

Therefore, the cartridge case structure 100 of the present application can be easily rotated to remove the cap just like a cap of a mineral water bottle, and can be linearly pulled out. Therefore, the protecting cover of the needle cylinder bin structure and the protecting cap of the pre-filled injection needle cylinder can be simultaneously taken down through one step, so that the cap is taken off integrally. In addition, the problem that the direct pulling mode of the protective cap is not convenient and laborious is solved, and the problem that the needle head is blocked and polluted by fragments of the protective cap due to the screwing mode of the protective cap is avoided. At the same time, the needle 74 is hidden from view throughout the course, reducing the mental skill of the patient.

The syringe cartridge structure 100 also includes an end cap 40. The end cap 40 is coupled to the cartridge body 10 at a second end of the cartridge body 10, and the aforementioned radio frequency identification tag 46 may be disposed on an end face of the end cap 40 remote from the cartridge body 10 to be in proximity to the read coil 251 of the identification device 250. The end cap 40 may also be provided with an end cap snap 44 for securing the pre-filled syringe 70. When the pre-filled syringe 70 is inserted into the syringe cartridge structure 100, the end cap catch 44 may lock the flange 73 of the pre-filled syringe 70 so that it cannot be removed at will. In addition, a push rod through hole 48 is further provided on the end surface of the end cap 40, so that a main body push rod 261 of the main body 200 can push the piston 72 of the pre-filled injection syringe 70 through the push rod through hole 48, thereby performing an air discharging operation and an injection operation.

Therefore, the intelligent automatic injector can intelligently identify medicine information and angle information, intelligently adjust and control exhaust and injection parameters according to the identification information, realize intelligent exhaust and injection, and provide intelligent guidance according to the exhaust and injection process. In addition, the needle cylinder bin structure of the intelligent automatic injector adopts an integrated cap taking design and a hidden needle design, so that the operation can be simplified, the experience and the accurate control can be improved, and the self-injection effect can be improved.

The application has been described in detail with reference to specific embodiments thereof. It will be apparent that the embodiments described above and shown in the drawings are to be understood as illustrative and not limiting of the application. It will be apparent to those skilled in the art that various modifications or variations can be made in the present application without departing from the spirit thereof, and that such modifications or variations do not depart from the scope of the application.
