ABSTRACT:
A lightweight, personal, portable dispenser of medically pure oxygen at appropriate temperature and delivery rate for direct inhalation is disclosed. The dispenser contains an oxygen producing generator to initiate the creation of oxygen instantaneously from a fuel-less self-contained chemical reaction of extended shelf-life inert compounds in a totally safe and reliable generator. The oxygen initially enters an expansion chamber. A cylindrical dispenser body houses the oxygen producing generator and forms an annular space between the cylindrical dispensing body and the oxygen producing generator. A bottom web attached to the periphery of the bottom of the cylindrical dispenser body allows air from outside of the dispenser to enter the annular space formed between the cylindrical dispensing body and the oxygen producing generator and flow out the top of the cylindrical dispenser body. The oxygen passes through a cooling coil and the air flowing through the annular space cools the cooling coil and any oxygen flowing through it. In one arrangement, the cooling coil is formed within the annular space between the cylindrical dispensing body and the oxygen producing generator and forms a cylindrical helix.
