The main principles of operation room decontamination:
The concentration of suspended bacteria in the operating area can be controlled by air replacement in the operating room and controlling the direction of airflow, so as to achieve the effect of purification.
Operation room purification form:
Clean rooms can be divided into four categories according to their usage: industrial, biological, general biological and biological safety clean rooms. Operating room belongs to the general biological clean room. Its main function is to control the pollution of organic particles to the working object, and the internal pressure is generally positive. According to the air flow form, it can be divided into four kinds: one-way flow (laminar flow), non-one-way flow (turbulent flow), radial flow (oblique flow), mixed flow (local one-way flow) clean room.
Air purification is achieved by controlling the concentration of dust in the air. The purification efficiency of the purification system depends on the filtration efficiency of the filter. Current filters can be divided into initial efficiency, intermediate efficiency, high efficiency, sub-high efficiency, high efficiency and ultra-high efficiency according to different filtration requirements. Operation room purify is usually based on primary, middle and high efficiency filters. Inorganic and organic particulates can be filtered through filters to reduce the concentration of bacteria, which is the main reason why the purification system can reduce the concentration of bacteria in the operating room.
In actual use, due to the entry of personnel and equipment, the amount of dust (15.79 *106/min person) and bacteria (150-1000/min person) are the main sources of dust and bacteria in the operating room. The ratio of dust and bacteria is 500 1-1000 1.
The cleaning effect of operating room is to replace the concentration of dust and bacteria in polluted air with clean air under certain conditions for a certain period of time, so that it can reach the prescribed limit, so as to ensure the cleaning effect of operation. However, the purification system can not kill biological particles, but only reduces its quantity to a certain extent. Due to the material limitation of the filtration system, there may still be biological particles in the clean air, and the amount of bacteria in the room can not be replaced 100%, so the clean operating room should still adhere to routine disinfection, air purification as an auxiliary means of routine disinfection.
