It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.

[0032] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] Please combine Figures 1 to 5 , the injection pump provided by the utility model is now described. The injection pump is used in conjunction with a syringe 100. The injection pump includes a shell assembly 1, a cover body 14 and an injection assembly 2, the shell assembly 1 is formed with an accommodating space 15, the injection assembly 2 is installed in the accommodating space 15, and is used to push the syringe 100, the side wall of the shell assembly 1 is formed with an installation cavity 16 with an opening toward the accommodating space 15, the installation cavity 16 is used to install the power supply assembly 3, the cover body 14 is detachably connected to the shell assembly 1, and the cover body 14 is used to close the opening.

[0035] It can be understood that the shell assembly 1 of the injection pump is formed with a accommodating space 15, the injection assembly 2 is installed in the accommodating space 15, and is used to push the syringe 100 so that the medicine in the syringe 100 can be injected, and the side wall of the shell assembly 1 is formed with an installation cavity 16 with an opening toward the accommodating space 15, and the installation cavity 16 is used to install the power supply assembly 3, and the cover body 14 is detachably connected to the shell assembly 1, and the cover body 14 is used to close the opening, so that the power supply assembly 3 can be taken out from the installation cavity 16, so that the disassembly and assembly process of the power supply assembly 3 only requires opening the cover body 14 to take out the power supply assembly 3, and the disassembly and assembly of the power supply assembly 3 is relatively convenient, thereby facilitating the maintenance of the power supply assembly 3.

[0036] It should be supplemented that the first shell 11 and the second shell 12 enclose a receiving space 15. The mounting cavity 16 can be formed by being concave in the first shell 11 or in the second shell 12.

[0037] It should be noted that the power supply component 3 can be a battery.

[0038] In this embodiment, the cover 14 is provided with a snap-fit ​​piece, and the shell assembly 1 is provided with a snap-fit ​​groove, and the snap-fit ​​piece can cooperate with the snap-fit ​​groove to make the cover 14 detachably connected to the shell assembly 1. By providing the snap-fit ​​piece and the snap-fit ​​groove, the cover 14 can be detachably connected to the shell assembly 1, so that the power supply assembly 3 can be easily removed from the installation cavity 16, so as to facilitate the maintenance and separate transportation of the power supply assembly 3.

[0039] Of course, in other embodiments, the injection pump further includes a fastener 4, which passes through the cover 14 and is threadedly connected to the shell assembly 1, and the fastener 4 is rotated to separate the cover 14 from the shell assembly 1. Specifically, the fastener 4 is a screw or a bolt. The fastener 4 passes through the cover 14 and is threadedly connected to the shell assembly 1, and the fastener 4 is rotated so that the fastener 4 can be separated from the shell assembly 1, so that the cover 14 can be detachably connected to the shell assembly 1, so that the power supply assembly 3 can be easily removed from the installation cavity 16, so as to facilitate the maintenance and separate transportation of the power supply assembly 3.

[0040] In one embodiment, if Figure 2 As shown, the power supply assembly 3 is installed in the installation cavity 16 along the extension direction of the injection assembly 2. In this way, the installation of the power supply assembly 3 can save the volume of the injection pump, thereby facilitating the miniaturization of the injection pump.

[0041] In one embodiment, if Figure 2 and Figure 3 As shown, the injection assembly 2 includes a push-pull module 21 and a pump body module 22. The push-pull module 21 is exposed from the shell assembly 1, and the pump body module 22 is installed in the accommodating space 15. The pump body module 22 is connected to the push-pull module 21 and is used to drive the push-pull module 21 to move so that the push-pull module 21 can push the syringe 100 to inject the drug.

[0042] Specifically, the pump body module 22 includes a seat body, and a sliding group, a connecting shaft, a transmission group and a driving motor arranged on the seat body. One end of the connecting shaft is connected to the sliding group, and the end of the connecting shaft away from the sliding group is located outside the shell assembly 1 and connected to the push-pull module 21. The driving motor is driven and connected to the transmission group, and the transmission group and the sliding group are connected through a screw rod and a nut.

[0043] In this embodiment, the connecting shaft is a hollow shaft, the sliding group includes a first sliding member arranged on the seat body, and a second sliding member slidably connected to the first sliding member, and the transmission group includes a screw rod transmission-connected to the second sliding member. The screw rod is arranged parallel to the first sliding member and spaced apart, and is sleeved with the hollow shaft. Driven by the driving motor, the screw rod can convert its own rotational motion into the linear motion of the second sliding member, so that the second sliding member can slide relative to the first sliding member, thereby enabling the push-pull module 21 to reciprocate relative to the shell assembly 1.

[0044] In the related art, the push-pull module 21 is usually connected to the second sliding member through a connecting shaft, and the connecting shaft is arranged parallel to the screw rod and spaced apart, so that the connecting shaft and the screw rod need to occupy a larger installation space in the seat body, thereby making the volume of the injection pump larger.

[0045] In this embodiment, the connecting shaft is designed as a hollow shaft. While the hollow shaft is sleeved with the screw rod, it is also connected to the second sliding member. The screw rod can rotate in the hollow shaft to convert its own rotational motion into the linear motion of the second sliding member. Since the second sliding member can reciprocate along the axial direction of the screw rod under the drive of the driving motor, the second sliding member can drive the push-pull module 21 connected to the hollow shaft to reciprocate along the axial direction of the screw rod during the movement. Compared with the connecting shaft and the screw rod arranged in parallel and spaced apart, the sleeved hollow shaft and the screw rod can greatly save installation space, thereby making the overall structure of the injection pump more compact.

[0046] In one embodiment, if Figure 3 As shown, the injection pump further includes a power module 5, which is installed in the accommodating space 15 and electrically connected to the power supply component 3. By providing the power module 5, the power supply component 3 can supply power to the pump body module 22, so that the pump body module 22 can drive the push-pull module 21 to drive the injection pump to move, so that the medicine in the injection pump can be injected externally.

[0047] In this embodiment, the injection pump further includes a control component 6, which is installed in the accommodating space 15 and electrically connected to the injection component 2. By setting the control component 6, the pump body module 22 can be controlled to drive the push-pull module 21 to move, so that the push-pull module 21 can move at different speeds according to needs, thereby changing the injection speed of the drug in the syringe 100.

[0048] In one embodiment, the injection pump further includes an alarm light, which is mounted on the housing assembly 1 and is used to generate an alarm. Specifically, when the syringe 100 has completed injection, the alarm light generates an alarm, thereby prompting the operator to replace the syringe 100.

[0049] In one embodiment, if Figures 3 to 5 As shown, the injection pump further includes a door assembly 7, which includes a door frame 71 and a display component. The shell assembly 1 is provided with a receiving cavity for accommodating the syringe 100. The door frame 71 is rotatably connected to the shell assembly 1 and is used to open or close the receiving cavity so that the syringe 100 can be replaced. The display component is installed on the door frame 71. The door frame 71 is rotated so that the door frame 71 drives the display component to move, thereby opening the receiving cavity so that the syringe 100 can be replaced. The control assembly 6 is provided with a display component for receiving input instructions, thereby realizing different functions of the injection pump.

[0050] In this embodiment, the display component includes a display area 72 and a touch area 73. The display area 72 is used to display the operation corresponding to the touch area 73. Touching the touch area 73 can realize the function of the key, so that the touch area 73 can be waterproof and improve the reliability and aesthetics of the key.

[0051] Specifically, the touch area 73 includes a first touch area, and the first touch area corresponds to powering on or off the injection pump.

[0052] Furthermore, the touch area 73 also includes a second touch area, and the second touch area corresponds to starting or pausing the injection pump.

[0053] Furthermore, the door assembly 7 is provided with a first interface 61 and a second interface 62, which are provided at both ends of the door frame 71, the first interface 61 is electrically connected to the display area 72, and the second interface 62 is electrically connected to the touch area 73. In this way, the wiring of the injection pump can be facilitated and the installation convenience can be improved.

[0054] Further, the door assembly 7 further includes a display window 75, which is connected to the door frame 71 and is used to observe the syringe 100. The display window 75 and the door frame 71 can be integrally formed to facilitate assembly and waterproofing. By providing the display window 75, the drug inventory in the syringe 100 can be observed in real time.

[0055] Furthermore, the door assembly 7 further includes a vibrator 76, which is used to generate vibration when the touch area 73 is touched. Specifically, the vibrator 76 can be a micro vibration motor. After the user inputs a command, the vibrator 76 vibrates, so that the user can feel the feedback after the input command, thereby improving the user experience.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
