1. Strict purification
In the operation room wall four angle, cleaning unit, ceiling, corridor, fresh air machine, exhaust fan should be equipped with different levels of filters, and regular cleaning, maintenance and replacement of the indoor air, ensure strict aseptic operation room; in the design should be designed for all indoor wall arc structure, to avoid endless clearance dead; operation room purification should be using the appropriate air purification system, without the use of physical or chemical disinfection methods, can save resources into and can prevent the external pollution.
2. Positive pressure ventilation
The laminar flow operation room requires not only highly clean air, and can control the flow direction of the airflow, thereby forming a positive pressure in the indoor environment, so that the air flow from the high cleanliness operation area to the cleanliness of the area and take away and discharged dust particles in the airflow and bacteria. In addition, medical institutions can choose suitable purification engineering equipment according to their own actual needs.
3. Single channel flow
In the construction engineering design of purification for operation room, should design the transfer between doors and windows in the operation room and disinfection cabinet, and set up in and out of the single channel, need to be sterilized items through the "output" channel directly from the transfer to the operation room, disinfection cabinet, disinfection after the "input" channel is transferred to the operation room, so to avoid pollution two sterilization in the transfer process, so as to ensure that the environment of operation room always meet the work requirements.
