Laminar flow air supply method of different-temperature different-speed wide-opening low-speed air curtain suitable for operating room

Abstract

A different-temperature different-speed wide-opening low-speed air curtain laminar flow air supply method suitable for an operating room is characterized in that three independent air supply devices are arranged in the operating room and over an operating table and comprise a main laminar flow air supply device located in the center and wide-opening low-speed air curtain air supply devices on thetwo sides of the main laminar flow air supply device, and a plurality of air return openings are formed in the lower portions of the two sides of the long side of the operating table; air filters arearranged at the tail ends of the three air supply devices and the air return ports; the laminar flow air supply device in the middle feeds indoor circulating air with higher temperature and lower speedthrough the circulating unit (2), and air supply devices on the two sides feed air with lower temperature and lower humidity treated by the air conditioning unit (7); the whole air supply device of the system is in a different-temperature and different-speed air supply state of an air curtain and laminar flow.

Description

technical field [0001] This application belongs to the field of air conditioning. Background technique [0002] The local laminar flow air supply in the operating room is widely used in modern operating rooms. Laminar flow is just a common name, which is commonly used in the medical field. The different standards are referred to as unidirectional flow, low-turbulence displacement flow, or non-induced airflow. [0003] Regardless of the hospital construction standards of my country or other developed countries, high-level operating rooms often require local laminar air supply devices to be installed directly above the operating table. According to my country's GB50333-2013 "Building Technical Specifications for Clean Operation Departments of Hospitals", the air supply area of ​​the air supply device for Class I clean operating rooms is 2.4m×2.6m, and the air supply speed on the working surface is 0.2~0.25m / s , The air supply area of ​​the air supply device in the Class II cl...

Problems solved by technology

Difficulty reaching the work surface at times

Unable to guarantee a high degree of sterility and dust-free operation area

[0007]2. The temperature and humidity of the air supply cannot meet the needs of doctors and patients at the same time

The anesthesiologist who is on the patient's head will also feel cold, have a feeling of blowing, and feel uncomfortable
