Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen chambers, in particular to a pressure abnormality alarm structure for a civilian hyperbaric oxygen chamber. Background Art

[0002] Hyperbaric oxygen chambers can pressurize oxygen so that patients can absorb more oxygen in the chamber, increase blood oxygen concentration, and improve tissue function. Civilian hyperbaric oxygen chambers need to be equipped with abnormal pressure alarm structures to avoid dangerous situations such as explosions caused by excessive internal pressure. There are various abnormal pressure alarm structures for civilian hyperbaric oxygen chambers on the market.

[0003] For example, the utility model with the authorization announcement number CN219480692U discloses a pressure abnormality alarm structure for a hyperbaric oxygen chamber, which relates to the technical field of hyperbaric oxygen chamber auxiliary equipment, including a hyperbaric oxygen chamber main body, a hyperbaric oxygen chamber base is provided on the lower side of the hyperbaric oxygen chamber main body, a fixed base is installed on the right end of the hyperbaric oxygen chamber base, a detection chamber is provided on the right side of the hyperbaric oxygen chamber main body, a fixed block is provided inside the detection chamber, a sealing plug is provided on the inner side of the through hole of the fixed block, a gas pressure rod is connected to the lower side of the sealing plug, an infrared emitter is provided on the side wall of the output end of the gas pressure rod, an infrared capture frame is installed on the upper end of the fixed base, and an alarm is installed on the front bottom end of the fixed base. The infrared emitter provided on the side wall of the gas pressure rod will move synchronously with the sealing plug, and the infrared capture frame will be used to capture the position of the infrared emitter.
