本文以现实中塑料输血输液袋膜的的厚度不可测和无现实意义为由,提出了袋膜的平均厚度及其双层测试法,操作简便易行,结论科学客观,比单纯测定膜的厚度更为现实优越。《中国人民解放军药品制剂规范(1985年版)》[(以下简称《规范》)北京:人民军医出版社,1987附录207页]规定输血输液塑料薄膜容器“膜的厚度应为0.4mm～0.45mm”,这是包装容器质量全面落实GMP 的好事。但是,我们在实践中体会到:塑料输血输液袋“膜的厚度”仅在理论上是正确的,而在实际中一是难测,二是无现实意义。其理由是:1.目前国产塑料输液袋膜的厚度极不均匀,在同一只输液袋各处测得的数据都不相同,有的合格,有的不合格,
In this paper, the actual thickness of plastic transfusion bag is not measurable and has no practical significance, the average thickness of the bag film and its double-layer test method is proposed. The operation is simple and easy. The conclusion is scientific and objective, More realistic and superior. “Chinese People’s Liberation Army Pharmaceutical Preparations (1985 Edition)” [(hereinafter referred to as the “norms”) Beijing: People’s Medical Publishing House, 1987 Appendix 207] provides transfusion of plastic film containers “film thickness should be 0.4mm ~ 0.45mm” This is a good thing about the full implementation of GMP in the quality of packaging containers. However, we have realized in practice that the “thickness of the membrane” of the transfusion bag for plastic transfusion is only theoretically correct, but in reality, it is difficult to measure and the second is of no practical significance. The reason is: 1. At present, the thickness of domestic plastic infusion bag film is very uneven, measured in the same infusion bag around the data are not the same, some qualified, and some failed,
