[0002] Micro-hyperbaric oxygen chamber is a new type of rehabilitation assistive device that has emerged in recent years. However, due to the low space utilization rate and excessive size of existing micro-hyperbaric oxygen chambers, micro-hyperbaric oxygen chambers cannot be generally used. The oxygen chamber creates an atmospheric environment of 0.3-0.8kg / cm2. When people are in it, due to the increase in pressure, a large amount of oxygen dissolves in the blood, the amount of oxygen dissolved in the human blood increases significantly, and the blood oxygen partial pressure and blood oxygen diffusion capacity are increased, so that the effective diffusion radius of oxygen is increased. People breathe oxygen in the chamber for health care, providing effective and sufficient oxygen to the hypoxic body, increasing the oxygen content and oxygen storage capacity in the tissues, thereby playing a health care and treatment effect.

[0003] Traditional micro-pressure oxygen chambers often increase ventilation volume to control the carbon dioxide concentration in the chamber, which inevitably requires increasing the flow of the booster and oxygen generator, resulting in excessive noise and energy loss; using a breathing mask also faces the problems of cross-infection and poor exhalation.
