Problems solved by technology
At present, the infectious disease treatment area for the new type of coronavirus pneumonia mainly adopts negative pressure in the ward and medical staff wearing disposable protective equipment to protect against the virus. This method cannot completely isolate the possibility of the virus entering the protective clothing. In the case of rescue work, the mobility and comfort of the medical staff cannot be taken into account

Abstract
The invention provides a compressed air and oxygen supply dual-cooling protection system, which belongs to the technical field of cooling systems. The system comprises an air inlet main pipeline, an air exhaust main pipeline, an air inlet branch pipeline, an air exhaust branch pipeline, a compressed air oxygen supply station, a noise elimination and reduction device, an air purification device, a tail gas emission sterilization and purification device, a compressed air pipe conversion pressure reduction device, a suspension hose flexible moving device, a guide rail, a protective clothing air inlet / outlet hose and a double-cooling totally-closed protective clothing. After being pressurized, the air is conveyed to the air purification device to remove toxic and harmful particles in the air, flows to the internal main pipeline through the external pipeline, and then is connected to the branch pipelines of all the wards, so that the air is conveyed into all the wards. The air in the protective clothing air inlet hose is conveyed into the protective clothing, on one hand, the effect of supplying oxygen to people in the protective clothing is achieved, on the other hand, redundant heat and moisture in the protective clothing are taken away through flowing air, and the air flowing out of the protective clothing air outlet hose is conveyed to the external tail gas emission sterilization and purification device through the air outlet pipeline.
Description
technical field [0001] The invention relates to the technical field of cooling systems, in particular to a double cooling protection system for pressurized air and oxygen supply. Background technique [0002] Novel coronavirus pneumonia (COVID-19) is mainly transmitted through respiratory droplets and close contact. There is a possibility of aerosol transmission when exposed to high concentrations of aerosols for a long time in a relatively closed environment. During the treatment of patients, avoiding cross-infection between doctors and patients is a part that cannot be ignored. At present, the infectious disease treatment area for the new type of coronavirus pneumonia mainly adopts negative pressure in the ward and medical staff wearing disposable protective equipment to protect against the virus. This method cannot completely isolate the possibility of the virus entering the protective clothing. In the case of rescue work, it is impossible to take into account the flexib...
