Description

technical field [0001] The present invention relates to syringes, especially disposable self-destructing syringes. Background technique [0002] At present, when patients are injected intramuscularly, disposable syringes are widely used, which has played a positive role in preventing patients from cross-infection. However, in the actual application process, the medical staff did not destroy them in time after use, so that the lawless elements were recovered. Simple processing and then flow to the market, which brings security risks. Ordinary disposable self-destructing syringes require medical staff to install the needle and then remove the safety sheath during use, which makes the syringe more cumbersome during use, and the most important thing is to increase the risk of medical staff being stabbed. Contents of the invention [0003] The object of the present invention is to provide a disposable self-destructing syringe, which can realize self-destruction after use and r...
