Abstract:
1. A hyperbaric system, comprising: a chamber to receive oxygen at a predetermined high pressure, the chamber comprising a chamber body; a davit door assembly comprising a door, a davit arm, the davit arm rotatably attached to an inside wall of the chamber body, the door being capable of moving against a door frame so as to form a seal against the door when the chamber body is pressurized; a pair of thrust bearings, the thrust bearings being disposed inside the vertical portion of the davit arm, each thrust bearing comprising a top plate and a bottom plate, the top plate to move while the bottom plate is stationary, wherein the thrust bearings enable the davit arm to freely rotate along an arc, from a closed position against the door frame to a fully opened position against the wall of the chamber; and a pair of roller bearings, the roller bearings being disposed inside the vertical portion of the davit arm, each roller bearing being disposed upon a shaft such that, as the shaft rotates, balls inside each roller bearing turn against an outside surface of the roller bearings while an inside surface of each roller bearing remains stationary against the shaft, wherein the roller bearings enable the davit arm to rotate easily by keeping the main davit arm shaft from flexing or bending; and a control system, comprising: a floor assembly comprising a main floor, the main floor comprising a pie-shaped rigid plate coated with a static dissipative polyurethane material, a bottom flathead disposed upon a skirt of the chamber, the flathead having a drain hole disposed in its center and a sub-floor disposed beneath the main floor, the sub-floor being disposed at a slight slope, wherein waste automatically moves toward the drain during hyperbaric oxygen therapy treatment; and wherein the chamber body is pressurized to a set pressure sufficient for hyperbaric oxygen therapy treatment when the inlet supply line transmits oxygen into the chamber body.
