Problems solved by technology

Before use, you need to remove the protective shell to expose the needle body; after use, because the needle body is completely exposed to the outside and there is no safety protection structure, it is easy to cause accidental injury to others, and it is also easy to cause accidental injury due to accidental contact with the needle body. Circumstances leading to cross-infection
At the same time, since there is no necessary protective structure, the injection needle can be used again after use, so there is a risk of being reused

Abstract

The invention discloses a safe insulin injection needle. The safe insulin injection needle comprises an inner shell, a protective sleeve, a locking ring, a spring, a needle body and a needle base; a plurality of orbit changing devices are arranged on an inner wall of the inner shell; each of the orbit changing devices comprises a first guiding groove, a positioning groove, a first slip slope and apositioning bump; a plurality of guiding bumps are arranged on an outer side wall of the protective shell; a plurality of down-pressing bumps and down-pressing slopes are arranged at the lower part of the protective sleeve; a plurality of through grooves, elastic arms and positioning blocks are arranged on a side wall of the locking ring; and second slip slopes and transition slopes are arrangedon the positioning blocks. As for the safe insulin injection needle disclosed by the invention, the needle body can be automatically hidden after completion of injection; moreover, exposure of the needle body caused by touch by mistake is prevented, thereby avoiding harming people. Thus, the safe insulin injection needle is capable of avoiding cross infection; and the risk of repeated use of needles can be prevented.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a safe insulin injection needle. Background technique [0002] As a tool for treating diabetes, insulin injection needles have been widely used. Its main function is to control blood sugar in patients with diabetes by injecting insulin into their bodies. [0003] Insulin injection needles in the prior art generally include a needle base, a needle body and an outer protective shell. Before use, you need to remove the protective shell to expose the needle body; after use, because the needle body is completely exposed to the outside and there is no safety protection structure, it is easy to cause accidental injury to others, and it is also easy to cause accidental injury due to accidental contact with the needle body. Situations leading to cross-infection. At the same time, since there is no necessary protective structure, the injection needle can be used again after use...
