甲醛是一种强有力的消毒防腐剂。甲醛极易和蛋白质中氨基结合,使蛋白质变性,酶的活性消失,而起到杀灭细菌的作用。久置,能挥发出大量的有刺激性的特臭气。根据这一性能,临床上用36～38％甲醛所挥发的气体,来消毒医疗器械。到底气熏多长时间才有消毒作用,尚无定论。为此我们用36～38％甲醛溶液作了气熏器械消毒效果的观察。现报告如下。 Formaldehyde is a potent disinfectant preservative. Formaldehyde and protein easily amino group, the protein denaturation, enzyme activity disappeared, and play a role in killing bacteria. Long set, can emit a lot of irritating special odor. According to this performance, the clinical use of 36 to 38% of the volatile formaldehyde gas to disinfect medical devices. In the end how long the gas smoked disinfection, there is no conclusion. To this end, we used 36 ~ 38% formaldehyde solution for aerosol equipment disinfection effect observation. The report is as follows.
