Description

Technical Field

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

[0002] Insulin is a protein hormone secreted by the pancreatic beta cells in the pancreas in response to endogenous or exogenous substances such as glucose, lactose, ribose, arginine, glucagon, etc. Insulin is the only hormone in the body that lowers blood sugar and promotes the synthesis of glycogen, fat and protein. Exogenous insulin is mainly used to treat diabetes.

[0003] After insulin injection, the needle needs to be removed. The commonly used method is to manually rotate the needle to remove it. However, in daily use, it is found that since the insulin injection needle is small, manually rotating the needle to remove it requires the user to have a certain degree of hand flexibility and skills. For some people with poor hand function or older people, the operation may not be convenient, and it is easy to injure the user when removing the needle, causing the risk of cross infection. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an insulin needle disassembly device, which can tightly clamp the needle of the insulin syringe and improve the safety of use.

[0005] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0006] An insulin needle disassembly device comprises an expandable and closable V-shaped handle, the V-shaped handle having a left clamping handle and a right clamping handle, characterized in that: a left arc-shaped notch is provided on the upper inner side surface of the left clamping handle, and a plurality of left convex lines are provided on the inner arc surface of the left arc-shaped notch; a right arc-shaped notch corresponding to the left arc-shaped notch is provided on the upper inner side surface of the right clamping handle, and a plurality of right convex lines are provided on the inner arc surface of the right arc-shaped notch; when the left clamping handle and the right clamping handle are in a clamped state, the left arc-shaped notch and the right arc-shaped notch are closed together to form a combined clamping hole capable of accommodating the needle.

[0007] Under normal conditions, when the user does not pinch the left and right clamp handles tightly, the left arc-shaped notch and the right arc-shaped notch are in a relatively distant state. When the insulin needle is to be unscrewed, the user holds the insulin syringe in one hand and the needle removal device in the other hand, and puts the needle of the insulin syringe between the left and right arc-shaped notches. The user pinches the left and right clamp handles tightly, so that the left and right arc-shaped notches clamp the needle and then merge it into the clamp hole, and the outer wall of the needle contacts and cooperates with the left and right convex patterns, increasing the friction of the needle in the merged clamp hole and preventing the needle from slipping in the merged clamp hole; finally, the needle remains motionless in the merged clamp hole, and the user rotates the insulin syringe by hand until the insulin syringe is separated from the needle.

[0008] In the preferred embodiment, a left half sleeve is arranged on an outer edge of the left arc-shaped notch, and a right half sleeve is arranged on an outer edge of the right arc-shaped notch, and the right half sleeve and the left half sleeve are located on the same side of the combined clamp hole; when the left clamp handle and the right clamp handle are in the clamped state, the left half sleeve and the half sleeve are closed together to form a combined sleeve capable of accommodating the needle tip, and the outer end of the combined sleeve is a closed end. When the needle disassembly device clamps the needle of the insulin syringe, the needle tip is in the combined sleeve, and the needle tip is wrapped by the closed combined sleeve, which can prevent the needle from stabbing the user, and the needle will not be directly exposed to the outside during disposal, reducing the risk and difficulty in the process of medical waste disposal.

[0009] In a further preferred embodiment, the inner diameter of the combined sleeve gradually decreases from the inside to the outside. The combined sleeve with an inner diameter gradually decreasing from the inside to the outside can better fix the needle, reduce the shaking of the needle during the removal process, and enhance the stability of the operation.

[0010] In the preferred embodiment, a left thickened portion is provided on the inner side surface of the upper part of the left clamp handle, and the left arc-shaped notch is provided on the inner side surface of the left thickened portion; a right thickened portion is provided on the inner side surface of the upper part of the right clamp handle, and the right arc-shaped notch is provided on the inner side surface of the right thickened portion. The left and right thickened portions are stronger than other parts of the V-shaped handle. By providing the arc-shaped notch on the inner side surfaces of the left and right thickened portions, the structural stability and bearing capacity of the combined clamp hole can be improved, and the possibility of deformation and loosening of the combined clamp hole when clamping the needle can be reduced.

[0011] In a preferred embodiment, the V-shaped handle is made of hard plastic. Since hard plastic has high strength and hardness, using hard plastic as the V-shaped handle can provide sufficient support and stability, thereby increasing the durability and service life of the needle removal device.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model can tightly clamp the needle of the insulin syringe to prevent the user from being accidentally stabbed during the process of removing the needle, thereby improving the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS
