The HMS-1000 hyperbaric chamber series is a Class B, monoplace hyperbaric chamber designed to treat one (1) patient to a maximum operating pressure of three (3) Atmospheres Absolute (ATA) (~ 29.4 psi). The chamber uses 100% oxygen as both the pressurization and hyperbaric treatment gas. The overall external length of the horizontal cylinder configuration is 8.75 feet. Its internal diameter is 33.5 inches. It is constructed of acrylic, aluminum, and fine-grade steel. Single operator pressure control is achieved via a simple industrial Programmable Logic Device (PLD) controller. A low-voltage patient intercom provides communications between the patient in the chamber and the external chamber operators. HMS-1000 is designed, fabricated, and tested in compliance with the following FDA consensus standards: the American Society of Mechanical Engineers / Pressure Vessel for Human Occupancy (ASME/PVHO-1) and the National Fire Protection Agency (NFPA) 99, Health Care Facilities.
A mains electricity (AC-powered) hard-shelled vessel (e.g., metal, acrylic) in which a patient is placed to receive hyperbaric oxygen therapy (HBOT), the medical use of oxygen (O2) at a higher than atmospheric pressure. The device increases environmental O2 pressure above normal to promote movement of O2 into a patient's tissues. It typically includes an airlock(s) for patient/object entry, view ports, air valves, and a control panel. It is used to treat disorders that typically include decompression sickness, carbon monoxide poisoning, air/gas embolism, necrotizing tissue infections, and various injuries/wounds; it can also be used to study effects of pressure and decompression.
