ABSTRACT:
A modular flow control system for a hyperbaric oxygen chamber which receives oxygen gas from a pressurized source and vents a mixture of oxygen and other gases from the chamber to atmosphere. The control system is comprised of a control panel which is mounted to the exterior of the hyperbaric chamber. The control panel consists of an oxygen inlet which is connected to a source of pressurized oxygen and provides access to a system supply line contained within the control panel. The system supply line contains a series of control and gauges which monitor and control the pressure of oxygen within the chamber and the flow rate of oxygen into the chamber. The system supply line terminates at an oxygen outlet which is connected directly to the hyperbaric chamber. Vent gas flows from the hyperbaric chamber back to the control panel through a vent gas inlet. The vent gas inlet is connected to a system vent line. The system vent line contains a series of valves and meters to control the flow of vent gas from the hyperbaric chamber. The system vent line terminates at a vent gas outlet contained in the control panel. A manually operable vent valve is contained in a bypass between the system supply line and the system vent line. The bypass allows the user to vent the supply of pressurized oxygen in a perceived emergency. Each of the connections to the control panel are made by a quick disconnect coupling which allows the control panel to be quickly and easily removed from the hyperbaric chamber.
