A closure mechanism and seating controls in combination with use with a hyperbaric chamber are described. The closure mechanism in combination with a hyperbaric chamber includes a door opening, a chamber door with dimensions larger than the door opening, a ring of sealing material secured to either the outer surface of the door or the inner surface of the chamber, a means for positioning the door adjacent the door opening and a means for pressurizing the chamber to effect a seal. The closure mechanism also includes an upper rail and pivoting carriers that may slide along the rail and a lower track mounted adjacent the floor and door guides that may slide within the track. The carriers and door guides are mounted to the interior surface of the door. The door and chamber walls may be flat, or curved in one or more planes. A locking mechanism is provided that employs a sliding wedge-shaped member that engages a retaining bar to secure the door in a closed position and a stop for securing the door in an open position. The seating controls in combination with a hyperbaric chamber provide means to swivel a seat support bracket about a base secured to the chamber floor and means rotate a seat about the bracket so that a patient can be easily and comfortably positioned within the chamber. Means are provided to lock the seat in a variety of positions including inclining the seat back.
