新出厂的塑料滴眼瓶清洗不彻底会污染滴眼液。过去,我们在使用新的塑料滴眼瓶时,只用常水洗两遍,蒸溜水洗三遍,再用蒸溜水煮沸30分钟。煮沸时由于有些滴眼瓶浮在水面上,达不到消毒目的。眼药瓶小盖带凹槽,刷洗困难,煮沸消毒后易变形,很难盖到眼药瓶上去。因此,有一段时间就不煮沸,只用常水和蒸溜水洗几遍就用。所用的器械和滤材也没有消毒(此操作方法下称“旧法”)。我们对在这样条件下配制的0.25%氯霉素眼药水进行了染菌检查。共查了三批160瓶,结果长菌的共有33瓶,染菌率为21%。
New factory plastic eye drops bottle cleaning will not completely pollute eye drops. In the past, when using a new plastic eye drop bottle, we just washed twice with regular water, distilled water three times, and then boiled in distilled water for 30 minutes. When boiling because of some drops on the surface of the bottle, can not reach the purpose of disinfection. Eye drops small lid with a groove, brushing difficult, easy to deform after boiling disinfection, it is difficult to cover the eye drops up. Therefore, there is a period of time without boiling, only regular water and steam wash several times to use. The instruments and filters used are not sterilized (this method is called “old method ”). We tested for contamination with 0.25% chloramphenicol in this condition. Three batches of 160 bottles were investigated. As a result, a total of 33 bottles of bacteria were obtained, and the rate of infection was 21%.
