Abstract

A hyperbaric oxygen therapy system includes a pressure vessel containing a gas, an oxygen concentration measurement apparatus for monitoring the concentration of oxygen in the gas, 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. The pressure vessel is capable of accommodating a patient. The oxygen concentration measurement apparatus includes an oxygen concentration analyzer and a plurality of gas lines connecting the oxygen analyzer to the pressure vessel. The pressure/ventilation control apparatus includes a pressure controlling valve, a pressure sensor, a ventilation valve, and a controller having a programmable pressure profile. The environmental control apparatus includes a scrubber, a heat exchanger and a blower located within the pressure vessel. A compressor for the system includes a compressor silencer. An airlock providing access to the pressure vessel includes a safety mechanism.

Claims5

Dependent claims

A compressor including an intake, an outtake and at least one compressor silencer connected to at least one of the intake and the outtake, the at least one compressor silencer comprising:

a silencer housing including an elongate body having an inlet end, an outlet end, an outer surface and an opposing inner surface, the inner surface defining an interior lumen through which gas flows from the inlet end to the outlet end;
an inlet cap secured to the inlet end of the body;
an outlet cap secured to the outlet end of the body;
and
a porous packing material that reduces noise created by the compressor, the packing material located within the interior lumen of the elongate body and filling at least part of the volume of the interior lumen between the inlet end and the outlet end of the body, the packing material extending radially outwardly from a point along a central longitudinal axis of the interior lumen to the inner surface of the elongate body, the packing material being supported by the inlet cap and the outlet cap;
and at least two elongate support rods mounted within the elongate body and extending between the inlet end and the outlet end of the body, an entirety of each elongate support rod being located radially outside of the interior lumen of the elongate body.
