Description
Technical Field
[0001] The utility model belongs to the technical field of oxygen chambers, and in particular relates to a flange profile assembled type oxygen chamber. Background Art
[0002] Traditional oxygen chambers, namely low-pressure oxygen chambers, are widely used in the medical and beauty fields because of their ability to provide high-concentration oxygen. However, with the development of science and technology and people's increasing demand for health, low-pressure oxygen chambers have gradually exposed their limitations. In a low-pressure environment, the oxygen supply speed is slow and cannot quickly penetrate into the body's cells, limiting the effect of oxygen therapy. Hyperbaric oxygen chambers, with their characteristic of providing high-concentration oxygen under high-pressure conditions, are considered a powerful weapon for eliminating aging cells in the body. In a high-pressure environment, oxygen can quickly penetrate into cells, restart the body's vitality, and help eliminate the body's decayed cells. Therefore, hyperbaric oxygen chambers are known as "time beads" and have broad application prospects.
[0003] Most of the oxygen chambers currently available on the market are medical hyperbaric oxygen chambers and civilian micro-pressure oxygen chambers, both of which have their own advantages and disadvantages. Medical hyperbaric oxygen chambers have a higher pressure value and are suitable for the treatment of critically ill patients and clinical diseases, which ordinary people will feel uncomfortable with. They are usually large chambers that can accommodate more than 6 people at the same time and occupy a large area. They also require appointments and queues, which is very troublesome and not very comfortable. Medical hyperbaric oxygen chambers are professional medical equipment with high operating difficulty. They can only be operated by certified medical staff at the operating table and inspected by certified maintenance personnel, and can only be purchased and used by medical institutions. However, the pressure of civilian micro-pressure oxygen chambers is relatively small, and ordinary people feel the most comfortable, safest, and most effective when using them; but they have no obvious effect on the treatment of critically ill patients.
[0004] In the prior art, a civilian hyperbaric oxygen chamber is designed by combining the advantages of medical hyperbaric oxygen chamber and civilian micro-pressure oxygen chamber; however, the civilian hyperbaric oxygen chamber in the prior art has the following problems: the oxygen chamber has weak pressure bearing capacity and poor rigidity, resulting in large deformation of the oxygen chamber after pressurization. The deformation visible to the naked eye will cause discomfort or even fear to the user; because the oxygen chamber belongs to a closed environment, it is easy to cause claustrophobia to the user. Therefore, in view of the above problems, it is urgent to develop a flange profile assembled oxygen chamber with strong pressure bearing capacity, good rigidity and suitable for civilian use.

It is suitable for single, double, and multiple people, and can accommodate more users at one time.
