脉动真空高压蒸汽灭菌全程报警装置的研制

Development of whole-course alarm unit for pulsating vacuum high-pressure steam sterilization

目的:针对脉动真空高压蒸汽灭菌过程中出现膜片、胶条密封不良,门、球阀关闭不严,蒸汽气压、水压不稳等情况易导致灭菌失败。特设计一种灭菌全程报警装置,对自来水源压力、抽真空能力、灭菌计时．灭菌压力、干燥计时进行实时监测,当任一程序出现异常时,报警装置将发出报警信号,提醒消毒人员及时排除故障,使灭菌效果进一步得到保障。

Some malfunctions can make pulsating vacuum high-pressure steam sterilization fail, including incompletely sealed diaphragm and strip, improperly closed gate and ball valves, unstable steam pressure and hydraulic pressure. This paper develops a whole-course alarm unit for vacuum high-pressure steam sterilization to monitor hydraulic pressure, vacuumizing ability, sterile time, sterile pressure and drying time. When any of above parameters is out of order, the unit alarms.
