Patent ID: 7263995

Claim:
A hyperbaric oxygen therapy system comprising: a gas compressor for compressing gas, the gas compressor including an intake, an outtake and a first silencer connected to the intake; a pressure vessel containing the gas from the gas compressor, the vessel being capable of accommodating a patient, the pressure vessel having a second silencer coupled to the outtake of the gas compressor, the second silencer being positioned within the pressure vessel; an oxygen breathing line at least partially within the pressure vessel, the oxygen breathing line delivering a supply of substantially pure oxygen to the patient within the pressure vessel; an oxygen concentration measurement apparatus for monitoring a concentration of oxygen in the gas, the oxygen concentration measurement apparatus including an oxygen analyzer coupled to one of an electronic and an electro-chemical oxygen concentration sensing unit that provides an electrical output signal representative of the concentration of oxygen in the gas to the oxygen analyzer, the oxygen analyzer displaying an indication of oxygen concentration based on the electrical output signal, the oxygen analyzer including a user adjustable high alarm threshold and one of an audible and visual alarm, the respective one of the audible and visual alarm being activated when the concentration of oxygen in the gas is greater than or equal to the high alarm threshold; a sampling system coupling the oxygen analyzer to the pressure vessel configured to conduct the gas from an interior of the pressure vessel to the oxygen analyzer from a plurality of separate locations in the pressure vessel; an environmental control apparatus for controlling the temperature of the gas in the vessel; and a pressure/ventilation control apparatus for controlling the pressure of the gas in the vessel.
