Laminar flow operating room air purification equipment air filter replacement daily management

The design of the laminar flow operating room requires a particularly high level of air cleanliness in the space. Generally, the cleanliness requirement is between one and one hundred. High cleanliness can effectively prevent complications caused by surgery and bacterial infection and health recovery of postoperative wounds. Therefore, the maintenance requirements for the purification equipment management and ventilation system in the laminar flow room are very strict. The following is a simple analysis of the daily management of purification equipment:

1. For the air outlets such as non-stop-proof orifice plates, grilles, wire mesh and central air-conditioning in the laminar clean area, it should be cleaned weekly. If there is pollution, it should be cleaned at any time;

2. Vertical grille should be used for the return air grille in the laminar clean area. Wipe clean once a day, thoroughly clean every week. If there is pollution, it should be cleaned at any time. The filter layer should be replaced in time according to the requirements;

3. After the end of each operation, the negative pressure operating room should be subjected to negative pressure for 15 minutes and then cleaned and wiped to achieve the self-cleaning requirement for the next operation. The exhaust filter for filtering the pathogenic aerosol should be replaced every six months;

4. The heat exchanger unit radiator should be sprayed with high-pressure tap water every week and kept clean and dry;

5. The internal humidifier of the air conditioner and the water tray and water tower under the refrigerator should be cleaned every week to remove dirt and keep it dry and clean;

6. The water retaining plate should be cleaned weekly and kept dry;

7. The drainage point for condensate should be inspected daily and cleaned weekly.

8. Daily standardization management and maintenance of laminar flow operating rooms for different functional purposes.
