Oxygen delivery system
DCFirst Claim
1. A portable gas delivery system comprising:
- a regulator having an accumulator chamber therein and a mixing chamber, the accumulator chamber configured to receive a gas, the mixing chamber in gaseous communication with the accumulator chamber and configured to form a gaseous mixture with the gas from the accumulator chamber by mixing in an ambient air;
means for discretely filling the accumulator chamber with the gas; and
an outlet in communication with the mixing chamber, configured to deliver the gaseous mixture from the mixing chamber.

Abstract
A portable gas delivery system is provided to provide oxygen or other gaseous mixture for use in emergencies, athletic events, and similar activities. The portable gas delivery system includes a regulator with an accumulator chamber disposed within the regulator and adjacent a mixing chamber. The accumulator chamber receives oxygen or other gas from a replaceable gas source such as a cylinder. The mixing chamber mixes ambient air and gas from the cylinder to form a gaseous mixture which is inhaled by a user. Each use of the portable gas delivery system may be in metered burst of predetermined duration and/or frequency or may be substantially continuous as provided for in the accompanying method.

36. A method of discretely filling an oxygen delivery system with measured quantities of oxygen, the method comprising the steps of:
-
a) providing the oxygen delivery system with a regulator having an accumulator chamber therein and a breathing outlet component disposed adjacent the accumulator chamber, the accumulator chamber configured to receive oxygen from a cartridge via a valve assembly attached to the regulator, the cartridge removably attachable to the regulator, the breathing outlet component configured to form a gaseous mixture with the oxygen from the accumulator chamber and an ambient air from external the oxygen delivery system, the breathing outlet component having an outlet therein to deliver the gaseous mixture externally; b) activating a valve assembly actuator disposed on the oxygen delivery system to controllably fill the accumulator chamber with oxygen, the valve assembly actuator operably connected to the valve assembly and configured to controllably bias the valve assembly to an open position to open an aperture in the accumulator chamber to permit oxygen from the cartridge to enter the accumulator chamber; and c) inhaling the oxygen from the accumulator chamber, the step of inhaling simultaneously drawing the ambient air into the breathing outlet component and forming the gaseous mixture. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
