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.

The HMS-2000 is a Class A, single compartment pressure vessel for human occupancy (PVHO) that is oriented in a vertical cylindrical geometry. The HMS-2000 hyperbaric chamber family of products is designed with non-dedicated seating, providing flexibility in managing seating arrangements. The diameter of the HMS-2000 varies in size; thereby enabling the ability to increase the patient capacity from three (3) to four (4) seated patients. An extension nozzle is attached to the chamber hull which provides the unique capability to treat one (1) patient in the supine versus seated position. The maximum allowable working pressure is three (3) Atmospheres Absolute (ATA) (~29.4psi). The control and operation of the HMS-2000 is performed from a hull mounted control console. The HMS-2000 multiplace hyperbaric chamber 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.

The HMS-4000 is a Class A, pressure vessel for human occupancy (PVHO) that is designed in a horizontal cylindrical geometry. Configurations vary from one (1) to three (3) compartments. These chambers are capable of administering hyperbaric oxygen therapy treatments to four (4) up to twenty-four (24) patients simultaneously. These chamber models comprise the HMS 4000 Horizontal Cylindrical Multiplace Hyperbaric Chamber System Product Family. Each system consists of a multiplace hyperbaric chamber with several major subsystems that are interconnected to form a complete system, which includes an operation control system that uses computer control technology. Design pressures range from 3ATA (~29.4psi) up to 6ATA (~73.5psi). The HMS-4000 multiplace hyperbaric chamber is designed, fabricated, and tested in compliance with the following FDA consensus standards: American Society of Mechanical Engineers / Pressure Vessel for Human Occupancy (ASME/PVHO-1) and the National Fire Protection Agency (NFPA) 99, Health Care Facilities.

The HMS-5000-12 is a Class A, pressure vessel for human occupancy (PVHO) that is designed in a rectangular geometry. It has two (2) compartments and is capable of administering hyperbaric oxygen therapy treatments up to twelve (12) patients simultaneously. It is one of the models contained within the HMS 5000 Rectangular Multiplace Hyperbaric Chamber System Product Family. It is comprised of a multiplace hyperbaric chamber with a number of major subsystems that are interconnected to form a complete system, which includes an operation control system that uses computer control technology. Pressures up to 6ATA (~73.5psi). The HMS-5000 multiplace hyperbaric chamber is designed, fabricated, and tested in compliance with the following FDA consensus standards: American Society of Mechanical Engineers / Pressure Vessel for Human Occupancy (ASME/PVHO-1) and the National Fire Protection Agency (NFPA) 99, Health Care Facilities.
