The SIGMA 40-II Hyperbaric System provides hyperbaric oxygen therapy for two patients. The maximum operating pressure is 30 psig (3 ATA). The system is pressurized with breathing quality air. Patients are seated in comfortable, adjustable, fully padded treatment chairs.
Patients breathe pure oxygen through a built in breathing system (BIBS), using “Duke” style hoods.
The SIGMA 40-II pressure vessel is constructed of aluminum end heads and includes a quick opening door assembly. A seamless clear acrylic plastic cylinder is held in sealed position between the end heads by four steel tie-rods. Safety interlocks prevent the chamber from being pressurized until the door is properly secured, and also prevents the door from being opened while the vessel is pressurized.
Patient Comfort is of utmost priority in the design of the SIGMA 40-II. The world’s largest diameter acrylic greatly reduces containment anxiety while the reclining seats maximize comfort during treatment.
The pressure vessel is mounted on a wheeled support chassis, which also houses the main control components. These components are tray mounted to provide easy access for maintenance.
The SIGMA 40-II is equipped with an adjustable height patient seat transfer gurney. The transfer gurney and seats are custom-designed to mate with the chamber and lock into position. Once the gurney is locked, the patients may be easily rolled into and out of the chamber on the seats.
