A valve apparatus especially well-suited for use in gaseous oxygen delivery systems. A valve apparatus is provided that substantially reduces the risk of fire in high-pressure oxygen systems. The apparatus is particularly well-suited for use as a plug valve on ordinary cylinder containers, but may be beneficially used in any pressurized gas system, particularly oxygen systems such as those encountered in many industrial facilities. The wetted portion of the valve is isolated from threaded portions to prevent particulate contamination of the gas stream. The valve seat is located to protect it from direct impact of high-velocity gas streams. The inventive valve, and its associated inventive check-filter and excess-flow prevention features, reduces the potential for hazardous combustion at valve points within oxygen delivery systems.

A pair of solenoid air/oxygen mixing systems used by an adaptive controller for delivering fractional inspired oxygen to a patient is described. The solenoid control system comprises either a bi-modal solenoid or a proportional solenoid air/oxygen mixing system to derive a fraction of inspired oxygen delivered to a patient. In the bi modal solenoid air/oxygen mixing system, a derived fraction of insipid oxygen is delivered to a patient. The bi-modal mixer uses a three-way valve solenoid. The solenoid has two input gas ports and one output gas port. Toggling between the two input port gases generates an output gas oxygen concentration. In contrast with the bi-modal solenoid, variation or proportionality between the two input port gases generates an output gas oxygen concentration. Both solenoid systems use a mini-computer and digital controller with software to control the fraction of inspired oxygen delivered to a patient. Finally, several therapeutic applications are described.
