Pulsating vacuum sterilizer is a commonly used sterilizer. The steps are as follows:
1. The pulsating vacuum sterilizer must be placed on a firm horizontal surface.
2. Add an appropriate amount of water to the outer pot, place the items to be sterilized in the inner pot, cover the lid and twist the screw symmetrically.
3. Heating causes steam to be generated in the pot. When the gauge pointer reaches 33.78 kPa, open the exhaust valve to discharge the cold air. At this time, the gauge pointer drops. When the pointer drops to zero, the exhaust valve is closed.
4. Continue to heat up, the steam in the pot increases, and the pointer of the pressure gauge rises again. When the pressure in the pot increases to the required pressure, the firepower is reduced. According to the characteristics of the sterilized items, the vapor pressure is maintained at the required pressure for a certain period of time. Then turn off or ignite the sterilizer, let it cool naturally, then slowly open the exhaust valve to remove the residual gas before opening the cover.
When using a pulsating vacuum sterilizer, pay attention to the following points:
1. The items to be sterilized should not be placed too tightly;
2. The cold air must be completely excluded, otherwise the temperature in the pot will not reach the specified temperature, which will affect the sterilization effect;
3. After sterilization, do not deflate and decompress, otherwise the liquid in the bottle will violently boil, flush out the stopper and overflow or even cause the container to burst. The lid must be opened after the pressure in the sterilizer has fallen to the same level as the atmospheric pressure;
4. When sterilizing liquid, the liquid should be filled in a heat-resistant glass bottle, no more than 3/4 volume, and the cotton yarn is used for the bottle mouth. Do not use perforated rubber or cork stoppers; after sterilization, do not release steam immediately, you must wait until the gauge pointer returns to zero before draining the residual gas.
5. Do not sterilize items of different types and different sterilization requirements, such as dressings and liquids, to avoid loss.
6. Now there is a high-pressure steam sterilizer that is automatically controlled by the microcomputer. After the air conditioner is placed, the instrument can automatically press the constant voltage. When the time is up, the power is automatically cut off and the whistle is uttered, which is convenient to use.
