1. Pre-vacuum pressure steam sterilizer: sterilization is realized by high-temperature and high-pressure steam.
2. Pulsating vacuum pressure steam sterilizer: a medical instrument that sterilizes high-temperature and moisture-proof articles by alternately vacuumizing and filling steam into the sterilization chamber for many times (filling saturated steam into the sterilization chamber after reaching a certain degree of vacuum), and finally reaching the set pressure and temperature.
Second, the use is different.
1. Pre-vacuum pressure steam sterilizer: the whole process of the equipment is automatically controlled, designed and manufactured in strict accordance with GMP standards, with advanced functions such as vacuum drying after high temperature and rapid sterilization at high temperature.
2. 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 pulse vacuum sterilizer and small pulse vacuum sterilizer.
Extended data:
Working principle of sterilizer:
1, thermal sterilization method is to use high temperature to coagulate or denature the protein of bacteria, so that the enzyme loses activity, metabolism is blocked, and bacteria die. Thermal sterilization includes moist heat sterilization and dry heat sterilization.
Thermal sterilization is convenient, effective and non-toxic, and it is the main sterilization method used in hospital disinfection supply center. Pressure steam sterilization is the preferred sterilization method for moisture-proof and heat-resistant medical devices.
2. Low temperature sterilization is a method of killing pathogenic microorganisms with chemical sterilization agents. When chemical agents are sterilized, the required temperature is low, which is usually called low temperature sterilization or chemical sterilization.
Chemical disinfectants used in low-temperature sterilization can kill all microorganisms and reach the sterilization guarantee level. This kind of chemicals with sterilization function include formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid and so on. Chemical sterilization is used to sterilize instruments that cannot tolerate high temperature and damp heat.
