[0002] The micro-hyperbaric oxygen chamber is a sealed chamber that provides high-concentration pure oxygen for users to breathe. The treatment effect is achieved by controlling the air pressure in the chamber. Normally, the air pressure in the chamber is adjusted to a micro-high pressure state, generally around 1.3 atmospheres. This micro-high pressure helps reduce bubble formation in tissues and promotes blood circulation. When undergoing treatment in a micro-hyperbaric oxygen chamber, the user needs to enter the chamber and stay there for a period of time. During the treatment, the user breathes high-concentration pure oxygen in a micro-high pressure environment, which can help improve blood circulation, reduce inflammatory responses, and promote wound healing. Micro-hyperbaric oxygen chambers have been widely used in the medical field, especially in oxygen therapy.

[0003] The micro-hyperbaric oxygen chamber is small in size, and the appropriate size of the chamber can be selected according to the number of users. Users can enter the oxygen chamber for health care treatment. With the development of technology, the micro-hyperbaric oxygen chamber is gradually being used as a health care device in the home.

[0004] In order to meet the needs of different families, oxygen chambers are constantly improving.
