Description
Technical Field
[0001] The utility model relates to the technical field of teaching tools, in particular to an air-conditioning system for positive and negative pressure switching and purification of an operating room. Background Art
[0002] The operating room is an important place for surgical operations in the hospital. The air cleanliness of the operating room is directly related to the success rate of the operation and the patient's postoperative recovery. Therefore, the operating room needs to maintain a highly clean environment to control and reduce the risk of infection during the operation. With the development of medical technology, the requirements for the air quality of the operating room are getting higher and higher.
[0003] Existing operating room air purification systems usually use air filtration and circulation to remove pollutants such as bacteria, viruses and particles in the air through sterilizers. Air sterilizers are a type of equipment that uses advanced technology to quickly kill all pathogenic microorganisms in the air, including bacteria, vegetative bodies, spore-forming fungi, etc.
[0004] However, in the process of treating the bacteria molecules in the air, the air flow speed is faster due to the negative pressure of the air, which leads to incomplete sterilization of the sterilization tank and affects the overall sterilization effect. Therefore, we propose a positive and negative pressure switching purification operating room air conditioning system to solve the above technical problems. Utility Model Content

The sliding connection groove 1 and the sliding connection groove 2 are symmetrically arranged, and the two are slidingly connected to the filter box.
[0012] As a preferred solution, a loading hole is provided on the filter box, and the loading hole is plugged into the filter cartridge.
[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:
[0014] This device is used to realize the flow of air in the operating room through the main body of the air-conditioning unit, and is used to sterilize the air inside the operating room through the air sterilization box fixedly installed on the main body of the air-conditioning unit. The multiple air inlet pipes fixedly installed on the air sterilization box are used to exhaust the air that has been preliminarily purified inside the air sterilization box. At the same time, the air preliminarily purified by the air sterilization box is further purified through the filter box fixedly installed on the air inlet pipe, so that the air purification is more thorough.
