Description

Technical Field

[0002] Background Technology Due to the high altitude, people in high-altitude areas are prone to hypoxia, which can lead to altitude sickness. Oxygen inhalation and hyperbaric oxygen therapy are common ways to relieve and treat altitude sickness.

[0003] A hyperbaric oxygen chamber (HBOT) is a medical device that treats a variety of diseases by providing an ambient pressure higher than atmospheric pressure (typically 1.5 to 3 atmospheres) and pure or highly concentrated oxygen. Its principles are based on Boyle's law and Henry's law, and it works by increasing blood oxygen solubility, improving tissue hypoxia, inhibiting anaerobic bacterial growth, and promoting angiogenesis. It is widely used in clinical fields such as decompression sickness, carbon monoxide poisoning, wound repair, and radiation-induced tissue damage.

[0004] Traditional hyperbaric oxygen chambers typically rely on externally supplied oxygen cylinders for oxygen supply, which has the problems of short supply time and frequent replacement. In addition, they all depend on a stable and reliable power grid for energy security. Once the cleaning is interrupted due to insufficient power, they are prone to failure to operate normally.
