About the working principle of pulsating vacuum pressure steam sterilizer
1. Meaning
Pulsating vacuum pressure steam sterilizer: through multiple alternations (three pulsating vacuums), the sterilization chamber is vacuumed and filled with steam (the sterilization chamber is filled with saturated steam after reaching a certain degree of vacuum), and finally the set pressure is reached and temperature, so as to realize the sterilization of high temperature and humidity resistant medical equipment.
2. Scope of use
Pulsating vacuum pressure steam sterilizer: used for moist heat sterilization of medical instruments and surgical instruments and drying after sterilization. According to the volume, it can be divided into large pulsating vacuum sterilizer and small pulsating vacuum sterilizer.
3. Sterilization principle
Thermal sterilization is the use of high temperature to coagulate or denature bacterial proteins, inactivate enzymes, and cause metabolic obstacles, resulting in bacterial death. Thermal sterilization methods include moist heat sterilization and dry heat sterilization. Thermal sterilization is convenient, effective and non-toxic, and is the main sterilization method used by hospital disinfection supply centers. The pressure steam sterilization method is the preferred sterilization method for moisture-resistant and heat-resistant medical devices.
