1. Stacking: wrap the drugs to be sterilized, and then put them on the sieve plate in the sterilization barrel in turn, leaving a proper gap between bags, so as to facilitate the overflow of cold air and the penetration of steam in the sterilization barrel and improve the sterilization effect.
2. Adding water: Add 4 liters of clean water into the sterilizer body, and the water will gradually evaporate during the sterilization process, and the water level will decrease accordingly. Therefore, before each sterilization, water should be added to the sterilizer to avoid dehydration, dry burning and damage to electric heating tube in electric heating tube.
3. Sealing: put the sterilization barrel into the sterilizer, insert the hose on the cover into the semicircular groove on the inner wall of the sterilization barrel, and close the cover. Align the bolt groove on the cover with the bolt groove on the main body, and then insert the butterfly nuts in opposite directions into the grooves in turn and tighten them evenly, so that the cover and the main body are tightly closed.
4, heating; Insert the power plug of the sterilizer into the 10A/220V external power socket. Turn the power switch to the "ON" position, the power indicator light will light up, and the electric heating tube will start heating. Then turn the wrench of the air release valve to the "air release valve" position, and turn the wrench of the air release valve to the "off" position when more urgent steam is ejected. At this time, the pointer of the pressure gauge rotates slowly clockwise, indicating that the pressure in the sterilizer is gradually rising and the temperature is also rising.
5. Sterilization: When the pressure in the sterilizer reaches the required range, users can start to calculate the sterilization time by themselves. According to different articles and packages, refer to Table 1 In the process of sterilization, users can properly adjust the heat source by turning on or off the power switch on the sterilizer, or connect the voltage regulating transformer to properly reduce the voltage, so as to keep the pressure in the sterilizer stable. However, the pressure to keep the internal pressure of the sterilizer constant cannot be lower than the value selected by the user. If the user does not adopt the above method to control the heat source, the safety valve will intermittently release overpressure steam during sterilization, and the set pressure inside the sterilizer is 0. 165MPa.
6. Drying: For articles that need to be dried quickly after sterilization, such as medical instruments, dressings, utensils, etc., the steam in the sterilizer can be quickly exhausted through the vent valve at the end of sterilization, and the lid of the sterilizer can be opened after waiting for 1~2 minutes. After opening the lid, continue heating for 10~ 15 minutes to evaporate the residual water vapor on the articles. Then turn the power switch to the "off" position to stop heating.
7. After the sterilized articles such as cooling medium and other liquids are sterilized, do not exhaust the steam in the sterilizer quickly through the exhaust valve, so as to avoid dangerous accidents such as overflow or bottle rupture caused by violent boiling of the liquid. Therefore, after this kind of sterilized articles are sterilized, turn the power switch to the "off" position, stop heating and wait for it to cool until the pressure gauge pointer returns to the "0" scale, wait for a few minutes, and then turn the bleeder wrench to the "bleeding" position. Then you can open the lid.
8, should often use the bottom thermometer, sterilization indicator or bacterial culture method to check the temperature and time required for sterilization, in order to obtain reliable sterilization effect.
