Now the medical and health conditions are getting better and better, and the laminar flow system in the operating room is becoming more and more perfect, which can largely avoid some unnecessary risks of surgery. The decoration of the laminar flow operating room below will summarize the components of the laminar flow system in the clean operating room.
1 Air purification
Air purification technology was used to reduce the microbial particles and the total amount of microorganisms in the air of the operating environment to the allowable level. In order to ensure the air cleanliness required by the operating environment, comprehensive measures are needed to achieve the goal. These measures include: (1) controlling pollution sources and reducing the amount of pollution; (2) effectively preventing outdoor air pollution from entering or spilling into the outdoor; and (3) quickly and effectively eliminating indoor air pollution. Pollution; (4) Flow rate control; (5) Air tightness of the system; (5) Control indoor temperature, humidity, wind speed, wind pressure and air volume, and appropriate cooling of instruments in the operating room, filtering floating particles in the air through initial, intermediate and efficient filters, so that fresh and clean air can be added to the operating room to avoid. Infection caused by pathogenic microorganisms brought in by various routes provides important environmental support for the success of surgery.
2 Composition of Clean System
The clean operating room is composed of air conditioning system and purification system. The air conditioning system mainly serves the purification system and provides heat or cold sources. The air conditioning unit and the air supply and return pipeline of the purification system constitute the air conditioning purification system. On the one hand, the purification system feeds clean air to dilute indoor polluted air, on the other hand, it expedites the discharge of indoor polluted air with high concentration. The technical means to realize the comprehensive measures include: filtration technology (three-stage filtration); air flow technology (supply air volume and flow pattern); pressure control technology (positive and negative pressure). The filtration technology ensures that the clean air is sent into the room, the air flow technology ensures that indoor pollution is diluted or discharged as soon as possible, and the pressure control technology controls the invasion of outdoor pollution. In case of sudden power outage, due to the temperature between clean operating rooms, the requirement of restoring power consumption is lower than that of medical instruments.
