To achieve oxygen therapy effects that are convenient for health care (such as beauty, wellness, health care, etc.) without the need for heavy and complex hyperbaric oxygen equipment. According to the latest medical achievements, in Inhaling oxygen rich gas under slight pressure (such as 0.03MPA) can achieve good oxygen therapy effects. The basic principle is to utilize the human body to fully relax under appropriate pressure And enable oxygen to be fully absorbed, thereby significantly increasing the oxygen partial pressure (blood oxygen content) in the human body< br> After breathing in the micro pressure chamber for a certain period of time with oxygen enriched micro pressure, under appropriate concentration of oxygen stimulation, blood vessels dilate and oxygen diffuses in the body, creating high pressure The oxygen chamber has a considerable effect. Thus achieving the effects of health preservation, beauty, and wellness.
