[0037] Working principle:

[0038] When removing a standard injection needle, if Figure 3 As shown, pull the rotating ring 5, which will cause the entire tube cutting assembly 4 to move downwards. Rotate the rotating ring 5 to contact the pull rod 43 and engage it at the top of the ring slot 6. At this time, the hook spring 8 is stretched and stored, and the tube cutting assembly 4 is restricted from resetting. Insert the syringe into the needle extraction port 7 and engage the part between the syringe and the needle in the engagement groove 101. Pull the syringe upwards to disengage the syringe and the needle. Then you can choose to continue using it, or rotate the rotating ring 5 to reset the tube cutting assembly 4. After the tube cutting assembly 4 is reset, the barrel 1 is sealed and isolated from the outside.

[0039] When removing the insulin injection needle, if Figure 3 As shown, pulling the rotating ring 5 causes the entire tube-cutting assembly 4 to move downwards, rotating the ring 5 to contact the pull rod 43 and engage it at the top of the ring slot 6. At this time, the hook spring 8 is stretched and stored, and the tube-cutting assembly 4 is restricted from resetting. Insert the insulin syringe into the needle retrieval port 7, so that the insulin injection needle is engaged in the needle-holding ring 10. Rotate the insulin syringe to disengage the insulin syringe and the injection needle. If you want to retrieve the insulin injection needle, you can use the next injection needle to push the injection needle stuck in the needle-holding ring 10 into the barrel 1. If you no longer want to retrieve the insulin injection needle, you can rotate the rotating ring 5 to release the hook spring 8, so that the tube-cutting assembly 4 resets. The pushing surface 12 on the slider 41 will contact the top of the insulin injection needle, push it into the barrel 1, and seal the barrel 1 to isolate it from the outside.

[0040] When the infusion needle is cut, pull the rotating ring 5 and move the entire tube cutting assembly 4 downward. At this time, the hook spring 8 is stretched and stored. Then, put the infusion tube and needle into the needle retrieval port 7 and release the rotating ring 5. The hook spring 8 is released and pulls the tube cutting blade 42. The impact force cuts the infusion tube, causing the needle to fall into the tank 1.
