Medical work in the most commonly used and most effective sterilization method is high-pressure steam sterilization method.
1, high-pressure steam sterilization is a sterilization method that can kill all microorganisms, including germ cells, is the best sterilization effect.
2, suitable for general culture medium, saline, surgical instruments, glass containers and syringes, dressings and other items of sterilization.
3, the method is to put the items to be sterilized in the autoclave, heating the steam does not overflow, the temperature inside the autoclave rises with the increase in steam pressure. Under 103.4kPa (1.05kg/cm2) steam pressure, the temperature reaches 121.3℃.
4, there are two major types of pressure steam sterilizers and pre-vacuum pressure steam sterilizers in the lower row. The lower row of pressure steam sterilizer and include portable and horizontal two kinds.
5, under the exhaust pressure steam sterilizer, the lower part of the vent, the use of hot and cold air specific gravity difference, with the help of steam pressure on the upper part of the container to force the cold air from the bottom of the vent.
Common sterilization methods in the medical industry:
1, radiation sterilization.
Radiation sterilization method refers to the sterilization of items placed in a suitable radiation source radiation gamma rays or suitable electron gas pedal electron beams occurring in the ionizing radiation to achieve the killing of microorganisms. Medical devices, containers, production aids, raw materials and finished products that are not damaged by radiation can be sterilized by this method.
2, dry heat sterilization method.
Dry heat sterilization method refers to the items placed in the dry heat sterilization cabinet, tunnel sterilizer and other equipment, the use of dry heat air to kill microorganisms or eliminate pyrogenic substances. Applicable to high temperature but not suitable for sterilization of items sterilized by moist heat sterilization method, such as glassware, metal containers, fiber products, solid test drugs, liquid paraffin, etc. can be sterilized using this method.
