[0040] It can be understood that the injection driving unit 40 can be any electrically controlled driving component that can drive the piston 22, such as a pneumatic cylinder, a hydraulic cylinder, etc.

[0041] In one embodiment, as shown in Figures 1-3 The injection driving unit 40 includes a driving module 41 and a driving rack 42. The driving rack 42 is slidably connected to the housing 10 and connected to the piston 22 of the injector 20. The driving module 41 is mounted in the control cavity 11 and connected to the driving rack 42, and is used to drive the driving rack 42 to slide. Specifically, during the driving process of the injector 20, the driving module 41 drives the driving rack 42 to slide, which pushes the piston 22 of the injector 20 to act, and realizes the microneedle injection.

[0042] In this embodiment, as shown in Figure 3 The control cavity 11 is fixed with a supply sliding rod 13, which extends in the pushing direction of the injector 20, and the driving rack 42 is slidably connected to the supply sliding rod 13. Specifically, the supply sliding rod 13 can realize the stable sliding of the driving rack 42 along the housing 10.

Specifically, the sliding groove 421 on the side of the drive frame 42 enables the drive frame 42 to slide stably along the supply slide rod 13, and the opening on the side of the sliding groove 421 facilitates the installation of the drive frame 42 and the supply slide rod 13.

[0044] Understandably, the drive module 41 can be any electrically controllable drive component, such as a cylinder or hydraulic cylinder, that can drive the piston 22.

[0045] In one embodiment, such as Figure 3 As shown, the drive module 41 includes a motor 411 and a lead screw 412. The lead screw 412 is rotatably connected to the control cavity 11 and threadedly connected to the drive frame 42. The motor 411 is fixed to the housing 10 and connected to the lead screw 412. Specifically, the motor 411 drives the lead screw 412 to rotate, which in turn drives the drive frame 42 to move axially along the lead screw 412. This causes the drive frame 42 to push the piston 22, thereby injecting the drug solution into the microneedle injection head 30.

[0046] In one embodiment, such as Figures 1-3 As shown, the housing 10 is provided with a sliding port 14 that communicates with the control cavity 11. The sliding port 14 extends in the pushing direction of the piston 22 of the syringe 20. The drive frame 42 passes through the sliding port 14 and is slidably connected to the side wall of the sliding port 14. Specifically, by passing through the sliding port 14 and slidably connecting to the side wall of the sliding port 14, the drive frame 42 achieves a sliding connection with the housing 10 while also limiting the movement on both sides through the sliding port 14, thereby improving the stability of the drive frame 42 and facilitating the driving of the drive module 41.

[0047] In one embodiment, such as Figures 1-3 As shown, a pressing head 422 is provided at one end of the drive frame 42 connected to the piston 22 of the syringe 20. The pressing head 422 is detachably fixed to the drive frame 42. Specifically, the drive frame 42 can push the piston 22 of the syringe 20 through the pressing head 422 to realize the delivery of the drug liquid in the syringe 20 to the microneedle injection head 30. Since the pressing head 422 is detachably connected to the drive frame 42, only the pressing head 422 needs to be replaced for pushing syringes 20 of different sizes, thereby improving the applicability of the booster device.

[0048] In this embodiment, the drive frame 42 is provided with a positioning post, which is inserted into the positioning hole of the pressing head 422 to realize the limiting and fixing of the pressing head 422.

Specifically, when the reciprocating driving unit 50 drives the microneedle injection head 30 to slide, so that the microneedles of the microneedle injection head 30 extend out of the sliding channel 12, the microneedles of the microneedle injection head 30 pierce the skin, the driving unit drives the syringe 20 to input the liquid medicine into the microneedle injection head 30, so that the microneedle injection head 30 performs microneedle injection on the skin through the microneedles, and when the reciprocating driving unit 50 drives the microneedle injection head 30 to slide, so that the microneedles of the microneedle injection head 30 enter the sliding channel 12, the driving unit stops driving the piston 22 of the syringe 20, and then the reciprocating extension and retraction of the microneedle injection head 30 realizes the reciprocating microneedle injection of the microneedle injection boosting device to the patient.

[0050] It can be understood that the reciprocating driving unit 50 can be any driving device capable of driving the microneedle injection head 30 to reciprocally slide, such as a pneumatic cylinder, a hydraulic cylinder, a motor screw module, etc.

[0051] In order to better understand the present application, the following will be described in detail Figures 1 to 3 The technical scheme of the present application will be described in detail: when performing microneedle injection work, the microneedle injection boosting device aligns the injection site through the microneedle injection head 30, the reciprocating driving unit 50 drives the microneedle injection head 30 to slide, so that the microneedles of the microneedle injection head 30 extend out of the sliding channel 12, the microneedles of the microneedle injection head 30 pierce the skin, then the motor 411 drives the driving frame 42 to push the piston 22 of the syringe 20, so that the syringe 20 quantitatively inputs the liquid medicine into the microneedle injection head 30, thereby realizing the quantitative input of the liquid medicine to the injection site, after the input of the liquid medicine is completed, the reciprocating driving unit 50 drives the microneedle injection head 30 to slide, so that the microneedles of the microneedle injection head 30 retract into the sliding channel 12, at this time, the microneedle injection head 30 aligns another injection site, and performs quantitative microneedle injection on the injection site, and finally the above cycle is completed to provide convenience for microneedle injection work.
