Description

Technical Field

[0001] The utility model relates to a needle disassembly device, in particular to an insulin needle disassembly device, and belongs to the technical field of medical supplies. Background Art

[0002] The insulin injection pen is a convenient and easy-to-use medical device that combines insulin drugs and injection devices into one, allowing patients to self-manage the injection process. Insulin injection pens are divided into reusable and disposable types. The injection needle of a reusable insulin injection pen is a disposable medical device. In order to prevent cross infection and other hygiene problems, the injection needle needs to be properly handled after use. Usually, an insulin needle remover is required to assist in the removal of the injection needle.

[0003] A Chinese public patent (publication number: CN215275112U) discloses an insulin needle removal device, which belongs to the field of medical auxiliary equipment.

A spring 605 is wound around the outer side of the rectangular groove 607. By pushing the circular plate 602 to move, the circular plate 602 drives the connecting rod 603 to move under the action of the connecting block 608. When the connecting rod 603 moves, the spring 605 is stretched. The movement of the connecting rod 603 also drives the first clamping piece 3 to move. The first clamping piece 3, the second clamping piece 4 and the anti-slip pad 5 cooperate with each other to clamp the insulin needle to prevent the insulin needle from falling out of the sleeve 2 after being removed but not discarded.

[0027] In one embodiment, a rectangular hole 7 is opened on one side of the sleeve 2 , and the inner wall of the rectangular hole 7 is in movable contact with the outer side of the connecting rod 603 , so that the connecting rod 603 can move on the inner wall of the sleeve 2 through the rectangular hole 7 .
