Abstract

The invention aims to provide a disposable safe self-destruction blood taking needle which is simple in structure and effectively insulates and protects a blood taking needle head. The disposable safe self-destruction blood taking needle comprises a casing, a needle storage bracket, a needle seat, a spring and a needle head, wherein a clamping groove and a spring hole are formed in the casing; a chute is formed on the periphery of the outlet of the spring hole; clamping buckles, lifting jaws, limiting clamps, sliding jaws and a needle outlet hole are arranged on the needle storage bracket; the needle head is aligned at the needle outlet hole and fixedly connected with the needle seat; the needle seat is mounted on the lifting jaws and connected with the spring; the clamping groove of the casing is connected with the clamping buckles of the needle storage bracket; the limiting clamps are located between the lifting jaws and the sliding jaws and used for preventing the needle seat and the needle head from being separated from the needle storage bracket, and mechanical automatic assembly is facilitated.

Description

technical field [0001] The invention relates to a disposable safe self-destruct blood collection needle, and more specifically relates to a device capable of rapidly puncturing subcutaneous capillaries and conveniently collecting blood samples when sampling and testing peripheral blood of a human body. It belongs to the field of blood sampling devices. Background technique [0002] At present, in order to prevent exposed blood collection needles, especially blood collection needles used by patients with high-risk diseases such as AIDS, from causing harm to medical workers and other personnel, medical institutions have gradually adopted blood collection equipment with safety protection functions, such as disposable Sexual safety blood collection needles and blood collection pens. The practice of one needle per person and isolation of needles has played a positive role in preventing cross-infection, preventing contact risks, and eliminating the fear of special groups such as ...
