Whether from a long-term perspective or the current analysis, Operating Room purification is an important hospital equipment, operating room purification is everywhere in the hospital, each hospital is indispensable operating room purification.
Most of the viruses and bacteria in the air filtered out by the purification Air-conditioning System are adsorbed on the suspended particles, therefore, as long as the number of suspended particles is controlled, effective control of air purification can be achieved. Purification of Air Conditioning Filtration will mainly filter out suspended particles in the air, which in turn will be able to adsorbed on it bacteria, viruses, especially laminar flow operating room purification of such high cleanliness requirements.
Filtering out microbial contamination and bacteria in the air can play a role in reducing postoperative infections. The main methods are:
Control the amount of floating particles occurring，rapidly and effectively removing the floating particles that have occurred indoors and effectively prevent outdoor particles from entering the room.
Electrostatic adsorption is a purification method used in many places nowadays. The use of dust to the electrical nature, the use of electrostatic adsorption principle, to reduce the amount of dust in the operating room space, but this way is more limited, mainly because of the static electricity may bring trouble to the surgery, affecting the operation of the operating room purification equipment. Electrostatic adsorption dust removal: pre-filtration - high-efficiency filtration - activated carbon adsorption, combined positive ion electrostatic adsorption sterilization, and the use of large air volume air purification, in order to ensure that the number of times the indoor air purification.
According to research shows that after thirty minutes of boot, the natural bacteria in the air among the air will be reduced, it will be able to make the air microorganisms in the operation to maintain at a low level, and in the conditions of someone's activities, the air bacterial content with the prolongation of the disinfection time and reduce.
Ultraviolet disinfection and sterilisation is a commonly used method of spectral disinfection in hospital operating rooms, and is also suitable for laminar flow operating room purification project. The ultraviolet germicidal lamp will be hung on the ceiling of the room, and irradiate and disinfect in a vertical downward irradiation or reverse irradiation way. Radiation intensity should be higher than 70μW/㎝², to ensure 1.5W/m³, uniform distribution, hanging height 1.8 ~ 2.2m, continuous irradiation of not less than 30min, can make the static air to meet the disinfection requirements. Mobile irradiation method, ultraviolet disinfection vehicle can be a region of the indoor air for centralised irradiation, with its mobility, not subject to fixed location restrictions. Indirect irradiation method using closed ultraviolet steriliser, such as air cylinder steriliser, wall-mounted electronic (ultraviolet) steriliser, indoor air disinfection in the presence of people, the use of air constantly through the steriliser cycle, repeated filtration and ultraviolet irradiation, to achieve the purpose of purifying the air.
To sum up, the operating room purification in the disinfection management is very need to do a good job, only so that the operating room purification project, in order to get a better use. And pay attention to the selection of protective agent varieties, the operating room purification of protective construction should pay attention to be able to maintain the operating room purification of breathable and waterproof.
