Working Principle and Technical Parameters of Laminar Flow Ceiling in Clean Operating Room
Release time:2019-10-14 source:
Laminar air supply smallpox in operating room - Clean air supply smallpox is a clean operating room and a clean air supply terminal in laminar flow ward. It has the functions of filtration, equalization and air flow compensation. The rationality of laminar flow air supply ceiling structure directly affects the air supply effect and purification level of operating room.
Laminar air supply ceiling is the crystallization of the experience and practice of operating room air supply terminal in the past ten years. Its superior performance has been proved by nearly 1000 operating rooms. The unique double-layer DPP equalizing network can make the air flow uniformly to the working area. The central air flow compensation device can effectively eliminate the influence of updraft caused by the heating of personnel and equipment on laminar flow.
Operating room laminar air supply smallpox - clean air supply smallpox working principle: air supply smallpox is composed of air disinfection and filtration system, fan power system, noise reduction system, operation control system and so on. During operation, the fan inhales the ambient air, which is filtered into the clean sterile air through the air purification and disinfection system, and then the clean air is sent to the sickbed area in the hood in the way of laminar flow. At the same time, the positive pressure is kept in the hood to prevent the dust particles and microorganisms in the outer space from entering the hood.
Characteristics of laminar air supply ceiling: laminar air supply ceiling is the end of clean air supply in clean operating room and laminar ward. It has the functions of filtration, equalization and airflow compensation. The rationality of laminar ceiling structure directly affects the air supply effect and purification level of the operating room. After more than ten years of practical experience in hospital use, the structure is advanced and reasonable. It can be divided into I, II and III operating rooms. The cold plate of the box is sprayed with plastic, and the lower frame is stainless steel, beautiful and durable. Clean air supply ceiling device is based on Ling's first leak-proof layer technology at home and abroad. The use of this equipment can reasonably distribute the air in the clean room and effectively ensure the cleanliness of the room (air supply surface level 100).
