Cleaning and sterilization of clean operating clean room modular

Although the clean operating room is well sealed and the decorative materials and medical equipment do not produce dust, for energy saving considerations, the purification and air conditioning system of many hospital operating rooms will also stop running when the operating room is out of use, which will cause the operating room to be out of use. Polluted by outdoor air, bacteria and dust particles in the outdoor air will also be brought into the operating room, so cleaning and sterilization work is very important; if there is a crew on duty, in a state of slightly positive pressure, such pollution can be avoided as much as possible; indoors should be carried out in real time For cleaning and disinfection, generally wipe the surface and ground of items with 0.5% chlorine-containing disinfectant every morning. The operating department must be cleaned and cleaned by wet method. The cleaning work must be carried out during the operation of the purification air-conditioning system; The operating bed, the wall surface of the closet and the floor should be wiped with water and disinfectant once a day before and after the operation, and thoroughly cleaned once a week. The glass cover on the shadowless lamp in the operating room should be wiped once a month. After the operation is completed, in the normal operation state of the purification air-conditioning unit, continue to exhaust air for about 15 minutes to exhaust the indoor dirty air, and then carry out cleaning and cleaning work.

Use special clean room cleaning materials and tools. Cleaning should be carried out from high-level areas to low-level areas in sequence. All external surfaces such as equipment, tools and equipment cabinets should be cleaned with a wet special cleaning cloth. Siding and door surfaces with glass, clean with liquid detergent, then wipe off the remaining water with a rag; cleaning tools should be made of fabric material that does not lose fibers, walls and ceilings are scrubbed with a neutral detergent solution, then rinsed, Use a sponge to absorb the remaining water; clean the sticky pads after each shift in the clean room, and replace the disposable sticky pads daily; in order to prevent cross-contamination, each clean room should use its special cleaning tools, and the cleaning tools should also be cleaned daily Disinfect and store it in a special room; each surgical dirt should be sorted and packaged on the spot immediately, all kinds of dirt must be put into a special waterproof and anti-piercing dirt bag, sealed and transported out through the special channel, and transported through the dirt corridor Go to the dirt room for special treatment. After the cleaning and sterilization work is completed, wait for all personnel to leave, and then turn off the circulating purification unit; first mop the ground with a mop soaked in detergent, then wipe it with a clean wet mop, and then use a sponge mop Or a vacuum cleaner that can absorb water to absorb the remaining water. In case of serious stains, it can be treated with a special cleaning agent; after cleaning, the purification air-conditioning system should continue to run until the specified cleanliness is reached before the next one. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean operating rooms and sterile rooms.

The supply air of the clean room enters the clean room modular after being filtered by the high-efficiency filter, which can be regarded as sterile air, but this process has no sterilization effect. The most effective way to sterilize the room is to use the purification air-conditioning system, but the purification air-conditioning system cannot provide the initial aseptic state of the clean room, and the sterilization method can make up for this defect; each clean room should have a perfect sterilization system, Organically combine purification air-conditioning technology and sterilization technology to ensure a clean and sterile indoor environment; the sterilization methods of hospital clean rooms mainly include ultraviolet irradiation, ozone and chemical disinfectant sterilization methods, and clean rooms should be based on the characteristics of use. To determine the sterilization method and cycle, some clean rooms need to be disinfected daily, while some clean rooms can be disinfected once a week. Ultraviolet radiation disinfection is widely used in many occasions that need to be disinfected in hospitals, such as indoor air, object surfaces, water and other liquids. The use time of the lamp is generally 1000h. The output intensity of the lamp should be tested regularly with an instrument. The ultraviolet radiation intensity of the new lamp should be greater than 90μw/cm2. When the ultraviolet radiation intensity of the lamp is lower than 70μw/cm2, it should be Replace; ambient temperature, the most suitable temperature is 20 ℃; ambient humidity, generally relative humidity is 40%-60%, ultraviolet sterilization effect is the best, and when relative humidity is 60%-70%, ultraviolet sterilization effect is reduced, humidity The environment higher than 80% has the greatest impact on the output of the ultraviolet lamp, and even has an activating effect on bacteria; when using the ultraviolet lamp to irradiate, the exposed objects to be disinfected should be irradiated for a long time, and the exposure should be irradiated as close as possible. damage, so it can only be used in an unmanned state.
