一次性使用医用注射器活塞体外细胞毒性检测

Cytotoxicity Evaluation of the Disposable Medical Syringe Piston

检测机构对一次性使用医用注射器活塞进行生物学评价时,多发现其呈细胞毒性。我们按卫生部提出的生物学评价试验选择指南及样品提供方意见,选取了基本生物学评价中的5项试验,对一批一次性使用医用注射器活塞进行了系统生物学评价,发现其有细胞毒性。进一步对其进行综合检测和分析后,发现原因可能是厂家清洗活塞后的洗液残留所致。此研究为客观评价一次性使用医用注射器活塞的产品质量,督促厂家改进生产工艺,保证产品安全提供了参考。

When some testing institutions performed biological evaluation to the disposable medical syringe piston, cytotoxicity was found. According to the biological evaluation testing Selection Guide proposed by Ministry of Health and the Comments of Sample Provider, We performed biological evaluation to one sample by using 5 tests of basic biological evaluation. Cytotoxicity was found, which was probably caused by the residue of the lotion. This research provides reference for objective evaluation of disposable medical syringe piston and safe guarantee of the product.
