2001年3月,在用化学指示卡监测下排气式压力蒸汽灭菌器灭菌效果时,有几包消毒包中心的化学指示卡未变为标准黑色。经检查,证明压力蒸汽灭菌器性能正常。随后结合用菌片检测,对指示卡未变标准黑色的原因进行了调查分析。调查发现,首先,指示卡未变标准黑色与其浸了水有关。因指示卡布放在易形成冷凝水的金属、玻璃等材料表面,蒸汽在物品表面形成的冷凝水浸湿指示卡,或由于包装时湿手浸湿指示卡,致使其变色不匀而不出现标准黑色。第二,指示卡布放部位的物品难以达到灭菌,指示卡未变标准黑色则是该
In March 2001, when using a chemical indicator to monitor the sterilizing effect of a vented autoclave, several packs of disinfection pack center chemical indicators did not become standard black. After examination, the pressure steam sterilizer proved normal. Then combined with the use of bacterial detection, the indicator has not changed the standard black color of the reasons for the investigation and analysis. The survey found that, first of all, the indicator card has not changed its standard black color and it is immersed in water. Due to the instruction card is placed on the surface of the metal, glass and other materials that can easily form condensed water, the condensate on the surface of the steam is soaked in the indicator card, or the wet hand is soaked in the package that the indicator card is not discolored Standard black. Second, it is difficult to sterilize the articles in the place where the indicator card is placed, and the indicator card has not changed the standard black,
