Application of a temperature and pressure detector to the preventive maintenance of hospital autoclaves

Abstract

Pressure steam sterilization is the preferred sterilization method for damp-heat resistant medical devices. This study aims to reveal the risk of sterilization failure by using temperature and pressure detectors to detect changes in the performance of the sterilizer. Six autoclaves in a general hospital were selected as the research objects, and the key sterilization parameters such as sterilization temperature, sterilization time, sterilization pressure, and equilibration time were verified, and the performance of the sterilizer was evaluated. This paper provides a new way to monitor the sterilization process and to detect hidden dangers.
