In the purification of laminar flow operating room, the requirement of indoor humidity is relatively high, but how to adjust the indoor humidity? What methods should be used to adjust the internal humidity and clean the equipment?
The cleanliness of the operating room is mainly distinguished by the amount of dust particles and biological particles in the air. Currently, NASA classification standards are commonly used. Purification technology through positive pressure purification air supply to control cleanliness, to achieve the purpose of sterility.
With the help of air purification system and sterile environment, the operating room can become a highly sterile environment for organ transplantation, heart, blood vessel, artificial joint replacement and other operations. The use of low toxic disinfectants and rational use are the effective measures to ensure the aseptic environment of the operating room, and the ventilation of the operating room purification project is very important.
The clean air is sent to the operating room for purification, and the positive pressure air is sent to the same air conditioning system to purify the air in the local environment, and then returns to the local environment to filter and circulate the shutter tube once. In the environment of too low humidity and too dry air, the floating dust on the surface of the object is easy to float in the air by walking or planking, and fall into the hands of the operator, causing the risk of wound infection.
