[0002] As a medical device that promotes human tissue repair by precisely regulating the oxygen concentration and pressure in the chamber, the micro hyperbaric oxygen chamber has been widely used in clinical treatment (such as carbon monoxide poisoning and wound healing), rehabilitation and health care, sports medicine and other fields.
[0003] Its core air conditioning system covers key links such as compressor air supply, filter impurity filtration, pipeline pressure control and sealing, and the performance degradation of any component may cause systemic risk.
