What are the components of laminar flow system in clean operating room? Ed's purification editor will give you the following answers from the following three aspects:
1 air purification
Air purification technology was used to reduce the total amount of microbe particles and microbe in the air of operation environment to the allowable level. In order to ensure the air cleanliness required by the operating environment, comprehensive measures are needed to achieve the objectives, which include: ① control the pollution source and reduce the amount of pollution; ② effectively prevent outdoor air pollution from entering the room or overflowing the indoor air; ③ quickly and effectively eliminate indoor pollution; ④ flow rate control; ⑤ air tightness of the system; ⑥ control the temperature, humidity, wind speed, wind pressure and air volume in the operating room, properly cool the heat generated by the instruments in the operating room, filter the floating particles in the air through the primary effect, medium effect and high-efficiency filter screen, so as to make fresh and clean air supplement into the operating room, avoid infection caused by pathogenic microorganisms brought in by various ways, and provide important environmental support for the success of the operation.
2. Composition of cleaning system
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 source. The air conditioning unit and the air supply and return pipes of the purification system constitute the air conditioning purification system. On the one hand, the purification system sends clean air to dilute the indoor polluted air, on the other hand, it accelerates the discharge of the indoor polluted air with high concentration. The technical means of comprehensive measures include: Filtration Technology (three-stage filtration); air flow technology (air supply 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 airflow technology ensures that the indoor pollution is diluted or discharged as soon as possible, and the pressure control technology controls the outdoor pollution invasion. In case of sudden power failure, due to a certain temperature in the clean operating room, the requirement of power recovery is lower than that of medical instruments.
3 instrument and equipment
(1) instruments and equipment. The equipment commonly used in clean operating room includes respiratory, anesthesia and emergency equipment, infusion pump, cardiopulmonary bypass machine, extracorporeal membrane oxygenation system, ECG monitoring, self recovery blood machine, invasive pressure monitoring and other vital signs monitoring and support equipment.
(2) power supply. The clean operating room shall be powered by independent two-way power supply. The emergency power supply must be set for the electrical equipment with life support, and the automatic power recovery time shall meet the following requirements: ① the electrical equipment with life support shall be able to realize online switching; ② the non treatment places and equipment shall be ≤ 15s, and the working time of emergency power supply shall be ≥ 30min.
Clean operating room purification project is a professional, comprehensive and difficult project with complex design and construction and high technical risk. Therefore, it puts forward high professional and technical requirements for purification engineering company, which requires purification engineering company to have high technical adaptability and flexibility. The purification engineering company needs an engineering team with rich experience in design, manufacturing, installation, comprehensive commissioning and after-sales maintenance to strictly guarantee the purification engineering quality of the clean operating room.
