A large hyperbaric chamber, also known as a multiplace hyperbaric oxygen chamber, is a medical device that can accommodate more than two people simultaneously. It delivers hyperbaric oxygen therapy in a sealed environment under pressure higher than normal atmospheric pressure.
Core Definition & Classification
Full name: Large Hyperbaric Chamber / Multiplace Hyperbaric Oxygen Chamber
Working principle: The chamber is pressurized (commonly 2.0–6.0 ATA). Patients breathe pure oxygen via masks or hoods to elevate blood oxygen partial pressure, facilitating tissue repair and physical function recovery.
Main types:
Hard-shell Chamber: Made of steel or carbon fiber. Standard equipment for hospitals, holding 2 to 40 persons with a working pressure up to 6.0 ATA.
Soft-shell Chamber: Inflatable and portable, designed for household and wellness use. Suitable for 6–8 persons with a pressure range of 1.3–1.5 ATA.
Key Features (vs Single-person Chamber)
Large capacity: Accommodates 2–40 patients for simultaneous therapy, ideal for hospitals, rehabilitation centers and high-end wellness institutions.
High safety: The interior is filled with ambient air instead of pure oxygen, greatly reducing fire hazards. Medical staff can enter the chamber for real-time monitoring and emergency treatment.
Wide compatibility: Wheelchairs and stretchers are accessible; compatible with ventilators, ECG monitors and other life-support devices for critical and special patients.
Comfortable experience: Spacious interior relieves claustrophobia. Equipped with seats, sofas and entertainment systems for improved comfort.
Main Application Scenarios
Clinical Treatment: Carbon monoxide poisoning, traumatic brain injury, stroke, sudden sensorineural hearing loss, diabetic foot, refractory wounds, etc.
Rehabilitation Medicine: Sports injury recovery, post-operation rehabilitation, neurological rehabilitation, chronic fatigue syndrome.
Wellness & Healthcare: Anti-aging, sleep improvement, stress relief and immunity enhancement (for high-end clubs and hotels).
Special Fields: High-altitude hypoxia treatment, diving decompression sickness, aerospace medical research.
Reference Technical Parameters
Working pressure: 1.3–6.0 ATA (2.0–3.0 ATA for standard medical use)
Chamber material: Carbon steel / stainless steel / carbon fiber (70% lighter, suitable for high-floor installation)
Dimension: Customized size, length 2–10 m, width 1.5–4 m, height 2–3 m
Control system: Dual automatic PLC and manual control; real-time monitoring of pressure, oxygen concentration, temperature and humidity
Market & Industry Trends
China has built Asia-Pacific's largest hyperbaric chamber group at Beijing Chaoyang Hospital, as well as the world's largest 40-person carbon fiber hyperbaric chamber in Suzhou.Industry development trends include lightweight carbon fiber design, intelligent AI monitoring, civil soft-shell chamber popularization, and integrated multi-function design combining oxygen therapy, red light therapy and Bluetooth audio.
