The ejection assembly can push and pull the clamping and fixing assembly.

[0025] See also Figure 2-Figure 6 The clamping and fixing assembly shown in the figure includes two clamping plates 4 arranged inside the cylinder 1, a clamping rod 5 is fixedly provided on one side of the clamping plate 4, the end of the clamping rod 5 away from the clamping plate 4 passes through the cylinder 1 and extends outwardly and is fixedly connected to the connecting rod 6, the end of the connecting rod 6 away from the clamping rod 5 is fixedly provided with an insertion rod 7, one end of the insertion rod 7 passes through the cylinder 1 and extends inwardly, one end of the insertion rod 7 is opened in a U-shaped groove 8, and a column rod 9 is fixed inside the U-shaped groove 8;

[0026] See also Figure 2-Figure 5 The clamping and fixing assembly shown in the figure also includes a pull rod 10, which is provided with an inclined groove 11. The column 9 is slidably arranged inside the inclined groove 11, and one end of the pull rod 10 is connected to the ejection assembly.

[0027] See also Figure 2-Figure 5 The ejection assembly shown in the figure includes a slide 12 provided at one end of the tube body 3 and located inside the cylinder 1. An ejection block 13 is fixedly provided on the side of the slide 12 close to the tube body 3. A slip ring 14 is provided on the outer sliding sleeve of the tube body 3. The outer wall of the slip ring 14 is fixedly connected to one side of the slide 12 through a support rod 15. A push rod 16 is fixedly provided on the side of the slide 12 away from the ejection block 13. One end of the push rod 16 passes through the cylinder 1 and extends outward and is fixedly connected to the cross plate 17. Both ends of the cross plate 17 are slidably provided on a U-shaped rod 18. Both ends of the U-shaped rod 18 are fixedly connected to the outer side of the cylinder 1, and one end of the pull rod 10 is fixedly connected to one side of the slide 12.

[0028] When disassembling and removing the insulin needle: first, insert the used needle into the interior of the barrel 1. At this time, the needle cap of the needle is located inside one end of the barrel 1, and the needle tip of the needle is inserted into the interior of the tube 3. When inserting the needle, one end of the needle can push the ejection block 13 inside the tube 3, so that the ejection block 13 moves to the side away from the partition plate 2. When inserting the needle, the staff holds the insulin pen in one hand and the U-shaped rod 18 in the other hand, and pulls the horizontal plate 17 with the fingers. By pulling the horizontal plate 17, the push rod 16 and the slide plate 12 move to the side away from the partition plate 2, so that the ejection block 13 slides out of the tube 3. At this time, the needle part is inserted into the tube 3, and the needle is placed inside the barrel 1;

[0029] When the slide plate 12 slides, the slide plate 12 drives the pull rod 10 to move synchronously. The movement of the pull rod 10 causes the column rod 9 slidingly connected in the inclined groove 11 to move synchronously, and the column rod 9 is fixedly installed inside the U-shaped groove 8. The U-shaped groove 8 is opened at one end of the insertion rod 7. The movement of the pull rod 10 drives the column rod 9 to slide inside the inclined groove 11. The inclined groove 11 is tilted, which can realize the radial displacement of the insertion rod 7 in the cylinder 1, so that the insertion rod 7 moves toward the outer wall of the tube body 3. When the insertion rod 7 moves in the radial direction, it drives the connecting rod 6 to move synchronously, which can drive the splint 4 and the clamping rod 5 at one end to move toward the inside of the cylinder 1, so as to clamp and fix the outer wall of the needle cap of the needle, thereby realizing the needle The needle is placed stably inside the barrel 1, and then the medical staff rotates the insulin pen to realize the disassembly and separation between the needle and the insulin pen. This operation can avoid direct contact between the medical staff's hands and the needle to cause punctures, and effectively improves the safety of the staff's operation of disassembling the insulin pen needle. The disassembled needle is located inside the barrel. At this time, the medical staff pushes the cross plate 17 to drive the push rod 16 and the slide plate 12 to move toward the side close to the tube body 3, so that the ejection block 13 can be inserted into the interior of the tube body 3. At this time, the splint 4 is separated from the outer wall of the needle cap of the needle and loses its clamping and fixing function, thereby realizing the ejection of the needle inside the barrel 1 and the pusher of the needle from the inside of the barrel 1;

[0030] The device has a simple structure and is convenient for medical staff to operate and use. By adding the barrel 1, the clamping and fixing component and the ejection component, the needle cap of the needle is conveniently clamped and fixed, and the needle is separated from the insulin pen when the insulin pen is twisted, thereby realizing the removal of the needle. This structure is suitable for needles with smooth outer walls of the needle cap and needles with anti-slip grooves on the outer walls, which can effectively improve the scope of use. The needle removed from the barrel 1 is ejected by the ejection component. This operation can avoid direct contact between the hands of medical staff and the needle to cause puncture injuries, effectively improving the safety of the staff's operation of removing the insulin pen needle.
