ABSTRACT:
A system for compactly safely storing and delivering oxygen has a plurality of elements interconnected by fluid lines and includes a liquid oxygen tank, a filler valve and a vent valve. The new system also includes a differential pressure gauge located between and in communication with the fill valve and the vent valve to permit monitoring the pressure differential in the system so that selective adjustments can be made in a timely and controlled manner to maintain the pressure within the system during filling at an optimum level. The system also has at least one pressure relief valve, a heat exchanger, a fluid pressure regulator, an oxygen flow control outlet and a phase selector valve, to thereby permit automatic selection as a function of pressure of whether oxygen supplied from the tank to the heat exchanger will be supplied as either a liquid or a gas. The system elements are all sized and arranged in relation to one another so as to provide a light-weight, compact system for safely storing and delivering oxygen which is suitable for use by a home-bound patient as well as in a movable vehicle, and otherwise where safety, weight and size are of concern.
