Hyperbaric oxygen chambers are specialized medical devices used for hyperbaric oxygen therapy. Their principle is to place the patient in a sealed chamber and then increase the pressure inside the chamber so that the patient inhales a high concentration of pure oxygen. The hyperbaric oxygen chamber consists of the chamber body, oxygen supply and exhaust system, air supply and exhaust system, electrical system, air conditioning system, control system, and safety system. The main raw materials of the hyperbaric oxygen chamber include steel, electrical components, and instruments. Direct material costs account for approximately 64.91%, and raw material costs are the main component of the main business cost. Manufacturing expenses account for about 26.37%, and direct labor accounts for about 4.79%. As of 2022, the indications recommended by the Hyperbaric Medicine Society have increased to 76 types, with rapid demand growth in areas such as wound repair and neurological rehabilitation. By 2025, diabetes patients are projected to exceed 140 million, and patients with cardiovascular and cerebrovascular diseases will reach 320 million. As an adjunctive treatment method, hyperbaric oxygen therapy has gained significant clinical recognition, driving the number of treatments from 9.8 million in 2022 to 17.5 million in 2024, boosting the market size of the hyperbaric oxygen chamber industry in China, which is expected to reach approximately 884 million yuan in 2024. The fast pace and high stress of modern life have made sub-health a common phenomenon. Micro-hyperbaric oxygen chambers, by improving blood oxygen diffusion efficiency, relieve fatigue and improve metabolism, aligning with the health need of shifting from ‘passive treatment’ to ‘active prevention.’ Especially in the field of chronic diseases, the number of patients with relevant indications is expected to exceed 32 million per year by 2025, directly increasing the rigid demand for oxygen chambers in medical institutions and homes. In 2024, the output of the hyperbaric oxygen chamber industry in China is about 1,262 units, with a demand of approximately 1,229 units.
