Description

technical field [0001] The invention relates to a medical and sanitary product, in particular to a safe self-destruction syringe. Background technique [0002] In the process of medical treatment, it is a common medical practice to use a syringe to inject medicine into a patient's body. Improper disposal of used syringes and needles will directly endanger the personal safety of others, such as the risk of disease infection or needle stick injury. Disposable syringes are used to reduce the risk of infection from shared needles. Therefore it is necessary to design a novel syringe that can protect the needle and destroy the syringe. [0003] There are only a few types of syringes on the market that can automatically retract the needle and safely self-destruct. Most of them use pre-pressed metal springs as the power to automatically retract the needle. The cost is high, the production is difficult, and the price is expensive. , cannot meet the needs of the huge market. In ad...
