Regional police pressure monitoring a patient area for medical gas piping systems shall meet the following requirements: 1, should be set compressed medical gas operating pressure exceeds the rated pressure ± overpressure, undervoltage alarm and a vacuum system pressure is lower than 20% 37kPa when undervoltage alarm; 2, the region should set alarm medical oxygen gas pressure display industry, each operating room should be set up visual alarms; 3. Regional alarms should be set at the nurses' station or other medical personnel to monitor the area oxygen in pressure swing adsorption (PSA) technology, to extract oxygen from the air in new equipment, its use of physical adsorption and desorption of molecular sieve filling molecular sieve oxygen concentrator technology in the oxygen when pressurized air can be nitrogen adsorption, the remaining oxygen is not absorbed is collected oxygen machine maintenance and price, after purification was turned into high purity oxygen. Specific work process compressed air purification dryers after purification by switching valve into the absorption tower. In the adsorption tower is molecular sieve adsorption of nitrogen, oxygen adsorption at the top of the tower are accumulated into the oxygen tank after hospital oxygen machine, and then by odor, dust filter and sterile filter that is access to qualified medical oxygen. The main constituent parts are: air tank, air compressor, cold and dry, oxygen hosts, oxygen cans. Small oxygen oxygen machine _ _ Ericsson provided Hebei Medical Engineering Co., Ltd.
