上海市卫生防疫站在实验室试制成一种用于监测高压蒸汽灭菌的生物与化学指示剂。该指示剂由热敏变色化学药物与嗜热脂肪杆菌芽胞悬液(含培养基)组成,合并封装于安瓿中,其液体红色透明。经实验室观察,保存一年,芽胞的抗力无变化。使用时,将安瓿放于灭菌物品的中央,或灭菌器柜室中温度不易达到的部位。当灭菌温度达到121℃,作用20分钟后,安瓿内
Shanghai Health and Epidemic Prevention Station in the laboratory trial made a biological and chemical indicators for monitoring high-pressure steam sterilization. The indicator consists of a thermochromic chemotherapeutic agent and a thermophilic Bacillus stearothermophilus suspension (containing culture medium), packaged in an ampoule, and the liquid is red and transparent. After laboratory observation, save one year, no change in spores resistance. When used, place the ampoule in the center of the sterilized item, or in a temperature-resistant area of the sterilizer compartment. When the sterilization temperature reaches 121 ℃, after 20 minutes, the ampoule inside
