Problems solved by technology

However, due to the structural problems of ordinary disposable syringes, some operators have used them twice or multiple times, and users' illegal operations have caused cross-infection. In order to prevent artificial recycling and reuse, people set up self-destruct devices on disposable ordinary syringes.
However, although the self-destructing disposable syringes can prevent the reuse of the syringes, the exposed needles of the syringes will cause a lot of inconvenience in the collection, transportation, and processing of the discarded syringes after use, and it is still possible to stab medical staff and others. Its related personnel, causing cross-infection of viruses and bacteria

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a safety injection needle. Background technique [0002] Safe self-destructing disposable syringes are widely used in the medical field to avoid virus cross-infection caused by using unhygienic syringes. However, due to the structural problems of ordinary disposable syringes, some operators have used them twice or multiple times, and users' illegal operations have caused cross-infection. In order to prevent artificial recycling and reuse, people set up self-destruct devices on disposable ordinary syringes. . However, although the self-destructing disposable syringes can prevent the reuse of the syringes, the exposed needles of the syringes will cause a lot of inconvenience in the collection, transportation, and processing of the discarded syringes after use, and it is still possible to stab medical staff and others. Its related personnel cause cross-infection of viruses...
