A clasp-type insulin pen needle

Abstract

A clasp-type insulin pen needle includes an injection needle housing and an insulin injection pen, the top end of the injection needle shell body is clamped with a needle protection conical cap, and the bottom end of the injection needle shell body is welded with the base of the needle shell body, A taper cap fixing seat is arrange at that top end of the base of the needle shell body, and an insulin injection needle is embedded in the center of the base of the needle shell body, A taper cap spring is arrange between that base of the needle shell body and the conical cap of the needle protection, Between the outer shell of the injection needle and the insulin injection needle, a needle protection conical cap is arranged, The needle protection cone cap is always snapped and fixed on the outside of the insulin injection needle before and during use, so that the user can be prevented from touching the needle during the process of taking the insulin injection needle, and the insulin injection needle after use can be prevented from being pricked to the hand during treatment, so that the insulin injection needle is safer to be treated.

Description

technical field [0001] The invention belongs to the technical field of insulin pen needles, and in particular relates to a buckle-type insulin pen needle. Background technique [0002] Insulin injection pen needle, the product performance structure and composition are mainly composed of a sheath, a needle tube, and a needle seat. It is a medical device that is convenient for insulin injection and is disposable. [0003] However, there are still some unreasonable factors in the existing insulin pen needles in the process of injecting insulin to patients. When the existing insulin pen needles are used: the insulin pen needles are sterilized before use, Packed in a fixed packaging bag, once unpacked, it needs to be used in time, otherwise the needle surface exposed to the outside world is likely to be contaminated with bacteria and viruses by the user's hands and other parts, and the used needles are usually discarded in the medical waste bin Centralized treatment, but the exp...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a buckle-type insulin pen needle to solve the above-mentioned background technology. Use it in time, otherwise the surface of the exposed needles will be easily contaminated with bacteria and viruses by the user's hands and other parts, and the used needles are usually discarded in the medical waste bin for centralized treatment, but the exposed needles need to be slightly Inadvertently, it is easy to accidentally injure the hand, and if the hand is stabbed, it is easy to be infected by bacteria and viruses in medical waste, which poses a big safety hazard
