Operating room is the environment that needs to be cleaned up in hospital. Once patients are infected during operation, it will bring serious consequences. Eliminating bacteria in the air is the primary task of the operating room purification project, which is to reduce the probability of infection after surgery. Today, the small edition of the operation room decoration summarizes three principles used in the clean operation room purification project, hoping to be helpful to everyone!
I. Principles of Air Filtration
Before entering the clean operating room, the air must be filtered with initial, intermediate and high efficiency in order to control microorganisms and non-microbial particles in the air. Initial filtration of particles and foreign bodies above 10 microns, intermediate filtration of planktonic particles within 1-10 microns, high-efficiency filtration of sub-micron particles below 1 micron, this is the initial and medium-efficiency filtration of particles, which is also the key part of the air supply system. Efficient filtration can filter out particulates and bacteria. It can be regarded as sterile and also a method of removing plankton in the air.
2. Non-Unidirectional Flow Cleaning Rule
The principle of this purification is to send the filtered and sterilized clean air to the clean operating room, then diffuse in the room and mix with the indoor air. The same amount of air is discharged through the return air outlet. The exhausted air has diluted the polluted air in the room, and the seriously polluted air in the room will be diluted to a level. Heng state.
3. One-way Flow Clean Room Rule
During the process from the supply surface to the return surface, it will be filtered and sterilized, and the airflow will not change when it passes through the section. Under the balanced pressure and airflow of the supply static pressure box and the high-efficiency filter, the flow velocity on the section of the whole clean operating room is uniform, and there will be no eddy current. Clean air flow is full of the entire clean operating room, and the principle of one-way flow clean room is to push out the role of the indoor dirty air to the outdoor, and then the indoor air is purified.
