The correct use of autoclave : High-pressure steam sterilization has the advantages of fast sterilization speed, reliable effect, high temperature and strong penetrating power. If used improperly, it may lead to failure of sterilization. Points to note when sterilizing: First, the initial treatment of disinfected items. Medical devices, sheets, and clothing that have been exposed to pathogenic microorganisms should be disinfected with a chemical disinfectant and then cleaned as usual. In particular, all kinds of articles after use in infectious wards should be strictly controlled, and then carefully disinfected, then cleaned and disinfected. For routine cleaning, first wash and scrub with detergent solution to remove oil, dirt and other dirt on the items, and then rinse with running water. Instruments and other items such as shaft joints, cogging and gaps should be opened or removed as much as possible for thorough washing. The washed items should be dried and packaged according to clinical needs to avoid re-contamination. Containers and delivery tools for removing pre- and post-contamination items should be strictly distinguished and clearly marked to prevent cross-contamination. Second, the packaging and container of disinfectant items should be suitable. The package is made of double-coated white cotton cloth, and the new cloth should be washed and then used before being used. The goods are packed with wire ropes, which should not be loosened and should not be too tight. When using the container, it can be used to block the invasion of external microorganisms and has good steam penetration. Such as a special syringe sterilization box, a storage tank for dressings, and the like. The civil aluminum box is difficult to enter due to steam, and the air inside the box is not easily discharged. The sterilization effect cannot be achieved by conventional sterilization. Test comparison shows that its pollution rate is much higher than that of medical aluminum boxes. Therefore, it is not possible to use a civilian aluminum boxed syringe or instrument for sterilization. Third, the disinfection of items should be reasonable. Too much sterilization or improper placement can affect the sterilization effect. The contents of the sterilizer should not be over-squeezed and should not exceed the amount of the pan. Try to sterilize similar items in one pot. If different types of items are put together, the temperature and time required for the sterilization of the items should be determined. When loading and unloading the items, the upper and lower sides should be crossed and staggered to leave a gap to make the steam easy to penetrate. The large disinfection bag should be placed on the upper layer. The small enamel box and the storage tank should be sterilized at the same time as the cloth and metal objects. The metal objects should be placed on the lower layer so that the two are basically the same. And condensed water generated in the sterilization of metal articles to wet the cloth. Fourth, exhaust the air. When using a high pressure steam sterilizer, the most important thing is to drain the air inside the pot. If there is air in the pot, the pressure indicated by the pneumatic needle is not the pressure generated by the saturated steam. At the same pressure, the temperature of the steam mixed with air is lower than the temperature generated by the saturated steam. 5. Reasonably calculate the sterilization time. The sterilization time includes: 1 penetration time, starting from the time when the sterilization temperature is reached in the pot, and the time when the most difficult part of the pot reaches the temperature; 2 maintenance time, the time required to kill the microorganism, generally The time required to kill the streptozoon spores is expressed; 3 safe time, the time required to ensure the exact assurance of sterilization. It is usually half of the hot death time, and its length depends on the disinfection item. Sterilization of easily conductive metal equipment does not require safe time. During the sterilization time, pay attention to the pressure gauge and adjust the intake air amount to maintain the pressure at the time until the sterilization time. During the sterilization process, if there is pressure and temperature drop, the temperature should be raised again and re-timed. 6. After sterilization. After the disinfection item is required to be dried, the indicator can be sterilized to meet the sterilization requirements. When taking sterile items, it should be strictly aseptic, cover the cover first, and close the vent hole in the storage tank. At the same time, it should be classified and placed in order. Exceeding the expiration date, the hot and humid season generally does not exceed seven days. Seven, to prevent super hot steam. Although the temperature of the superheated steam is high, like air, it cannot be condensed into water when it encounters a disinfectant, and it cannot release latent heat, so it is unfavorable for sterilization. The way to prevent superheat is to use the external steam extinguisher, do not make the temperature of the interlayer higher than the temperature of the disinfection chamber, the two should be similar. Do not let the steam with too high pressure enter the disinfection chamber; do not use high pressure steam during sterilization. Heat to the required temperature and then lower the pressure. Eight, pay attention to safety. Check that the sterilizer is in good working condition before each sterilization, especially if the safety valve is good. Decompression after disinfection should not be too fast and too fast. The pot door should be opened when the pressure gauge is returned to the “0†position. If the sterilizing pot is a bottled solution and suddenly opens the pan, the glass suddenly encounters cold air and is prone to burst. It must be noted that if the pan door is suddenly opened too much, the cold air enters in a large amount, and the steam around the bag is easily condensed into water. The blockage of the perforations of the cloth blocks the vapor discharge in the cloth and makes the articles moist. 9. Do not use an autoclave to disinfect any destructive materials or substances containing alkali metals. Disinfecting these items can cause explosions or corrosion of the liner and internal piping, as well as damage to the gasket.
