High-pressure steam sterilization requires that the weight of the dressing package does not exceed 5 kg.
High-pressure steam sterilization is to place the items to be sterilized in a closed pressure sterilization pot, and by heating, the water in the compartment of the sterilization pot is boiled to generate steam.
Wait until the water vapor rapidly drives away the cold air in the pot from the exhaust valve, then close the exhaust valve and continue heating. At this time, because the steam cannot overflow, the pressure in the sterilizer is increased. pressure, thereby increasing the boiling point and obtaining temperatures above 100°. Causes bacterial protein to coagulate and denature to achieve the purpose of sterilization.
Sterilization methods include high-pressure steam sterilization, dry heat sterilization, ultraviolet sterilization, chemical disinfection, ionizing radiation, etc. In the fields of medical care, pharmaceuticals, food processing, water treatment, etc., sterilization is a very important procedure, and it is necessary to select appropriate sterilization methods and equipment according to different situations.
Precautions for using high-pressure steam sterilizers:
(1) The water in the pot must be distilled or purified water.
(2) The items to be sterilized should not be placed too tightly.
(3) The lid nuts must be tightened symmetrically.
(4) The cold air must be fully eliminated, otherwise the temperature in the pot will not reach the specified temperature, which will affect the sterilization effect.
(5) After sterilization is completed, do not deflate or reduce pressure, otherwise the liquid in the bottle will boil violently, flush out the cork and overflow or even cause the container to burst. The lid cannot be opened until the pressure inside the sterilizer drops to equal to the atmospheric pressure.
