胰岛素注射针头重复性使用安全性评价

Safety evaluation of repeated use of insulin injection needles

目的考察胰岛素针头重复性使用的安全性。方法用医用注射针针尖穿刺力测试仪测量胰岛素针头重复穿过人造皮肤时的穿刺摩擦力,同时用光学显微镜观察针头的形状。结果经多次重复使用后,胰岛素针头对人造皮肤的穿刺摩擦力是逐渐增大的,其针头的形状也发生不同程度的弯曲。结论一次性胰岛素注射针头,重复使用会带来一定的危害,因此不能重复性使用。

Objective To investigate the safety of repeated use of disposable plastic insulin syringes in clinical practice. Methods Medical injection needle puncture force tester was used to determine the puncture force of the disposable plastic insulin syringes when going through the artificial skin. And,the needle shape was also observed. Results After repeated use,the frictional force of the needle on the artificial skin was gradually increased,and the shape was also changed. Conclusion Disposable plastic insulin syringes could have a bad effect after repeated use. Therefore,overspend of disposable plastic insulin syringes was inappropriate.
