关于一次性使用输液器药液过滤器漏气问题的探讨

Discussion on the leakage problems of Infusion Medicinal filter

目的：探讨分析生产过程中药液过滤器的漏气问题并提出控制方法。方法：通过对脱料过程及组装过程中药液过滤器内、外壳的测定，并对组装中所使用的环已酮浓度进行统计分析，从而确定影响药液过滤器漏气的原因并找出解决方法。结果：采用半自动脱模比采用自动脱模对药液过滤器的变形影响大；环己酮中PVC导管料浓度为4％时，药液过滤器的漏气率最小；改进后的组装机对药液过滤器漏气影响较小。结论：使用自动脱模的药液过滤器内、外壳，并使用PVC导管料为4％时的环己酮浓度，利用改进后的组装机进行组装，可有效控制药液过滤器的漏气，保证产品质量。

Objective：Analysis on the leakage problem of Medicinal filter in the production process and proposed control methods. Methods：Through the determination of the inner and outer shell of the medicine filter in the stripping process and assembly process, statistical analysis to the cyclohexanone concentrations used in the assembly process,to determine impact liquid filter leakage causes and identify solutions. Results：The effect on deformation of liquid filter of in semi-automatic stripping is larger than in automatic stripping. When the PVC tubing material concentration in the cyclohexanone is 4 %, the rate of leakage of Medicinal filter is minimal. Conclusions：Using the inner and outer shell of the medicine filter by automatic demoulding, and when using PVC pipe material of 4% concentration of cyelohexanone, using of improved Assembly machines for assembling, can effectively control the leakage of Medicinal filter and ensure product quality.
