高压灭菌器内的温度,一般均有气压计来表示,例如压力15磅时,表示锅内温度已达摄氏121.5度。如压力表有损坏或压力表指示得不准确时,所指的压力与锅内的实际温度即不相符合,如实际温度低于压力表所指示的,即起不到应有的灭菌作用。为了补偿这一缺点,利用纯粹固体药物有一定熔点的原理,选择熔点与所需灭菌温度相同的药物作成指示管,放入高压灭菌器内,如药已熔,说明已达到所需的温度。但是药物熔溶后。当温度降低,还能恢复固体状态,为了能更明显地看出它是否已曾熔溶过,可根据药物熔成液态后
The temperature inside the autoclave is usually indicated by a barometer. For example, when the pressure is 15 pounds, the temperature in the pot reaches 121.5 degrees Celsius. If the pressure gauge is damaged or the gauge is inaccurately indicated, the indicated pressure does not correspond to the actual temperature in the pot. If the actual temperature is lower than the pressure gauge indicates, the sterilizing effect will not be achieved . In order to compensate for this shortcoming, the use of purely solid drugs have a certain melting point principle, select the melting point and the required sterilization temperature of the same drug made of indicator tube, into the autoclave, such as the drug has melted, indicating that the required temperature. However, after the drug dissolves. When the temperature decreases, but also restore the solid state, in order to be able to see more clearly whether it has been dissolved, according to the drug into the liquid state
