A rotary insulin pen needle

Abstract

A rotary insulin pen needle includes a needle shield housing, the top end of the needle protective shell body is welded with a needle protective cap fixing seat, and a needle rotating fixing seat is embedded in the needle protection outer shell body, the top end of the needle protective cap fixing seat is bolted with a protective cap on the needle, and the inner side of the bottom end of the needle protection cap fixing seat is provided with a rotating fixing seat baffle plate, the outer side of the insulin injection needle of the invention is provided with a needle protective outer shell, theinsulin injection needle is telescopic, When an insulin needle is needed, the needle can be protruded by pushing the needle to rotate the holder, At that end of use, the insulin injection needle canbe shrink into the needle protective housing to prevent the needle from bee damaged and deformed, and the needle protective housing is of a combined structure, which is more conducive to the recoveryand reuse of the recover needle, meanwhile, the insulin injection needle after use can be prevented from being pricked to the hand when being treated, and is safer to be treated.

Description

technical field [0001] The invention belongs to the technical field of insulin pen needles, in particular to a rotary type insulin pen needle. Background technique [0002] Insulin pen injector is composed of needles, insulin pens, etc., and is a disposable medical device for adult diabetic patients to inject insulin. [0003] However, existing insulin pen needles still have some unreasonable factors in the process of injecting insulin to patients. When the existing insulin syringes are in use: the insulin injection needle is embedded in the needle holder, and the needle holder and the needle holder are connected to each other during use. Insulin injection pen screw connection, after use, the needle guard is usually snapped and fixed on the outside of the syringe needle, and then discarded in the medical waste bin, but the needle guard and the insulin injection needle are not very firmly engaged. The needle protection cover is easy to fall off during the processing of medic...

Problems solved by technology

[0004] The object of the present invention is to provide a rotating insulin pen needle to solve the above-mentioned background technology. The insulin injection needle is embedded inside the needle holder. The needle guard is snapped and fixed on the outside of the syringe needle, and then discarded in the medical waste bin, but the needle guard and the insulin injection needle are not very firmly engaged, and the needle guard is easy to dispose of during the process of discarding and disposing of medical waste The exposed needles are easily damaged and deformed, and cannot be recycled. At the same time, in the process of processing medical waste, the needles are easy to hurt the hands of the processor. Medical waste contains There are a lot of bacteria and viruses, and the hands after being stabbed are easily infected with bacteria and viruses in the waste, which poses a big safety hazard
