Abstract:
1. An overpressure protection system for use with a hyperbaric chamber, the system comprising: an oxygen supply; a secondary relief valve having an input and an output, wherein said input is in pressure communication with a hyperbaric chamber connected to an emergency vent valve, and wherein said secondary relief valve is configured to actuate upon occurrence of a predetermined pressure condition; a relay having an input in communication with said secondary relief valve output, a supply port in fluid communication with said oxygen supply, a normally-open output, and a normally-closed output in communication with said emergency vent valve; a valve actuator connected to said normally-open output and said normally-closed output; a shutoff valve interposed between said hyperbaric chamber and said oxygen supply, wherein said shutoff valve is actuatable with said valve actuator; and wherein said hyperbaric chamber has a chamber pressure, maximum chamber set point, and is connected to a chamber relief valve having a relief valve set point.
