  • Gas demand device, method of installation, gas delivery system, and method of use
    Patent number: 10744296
    Abstract: A gas demand device cycles through five successive operation phases: gas is prevented from flowing through the timing gas and demand gas flow paths; gas is allowed to flow through the timing gas flow path and gas is prevented from flowing through the demand gas flow path; gas is allowed to flow through the timing gas and demand gas flow paths; gas is prevented from flowing through the timing gas flow path and gas is allowed to flow through the demand gas flow path; and gas is prevented from flowing through the timing gas and demand gas flow paths.

  • Method and system for gas delivery including gas conserver
    Publication number: 20180228997
    Abstract: A pneumatic oxygen conserver delivering a constant minute flow volume rate to a nasal mask, face mask, or nasal cannula is rendered lightweight by using tubing connected between the conserver and an oxygen source as a reservoir of oxygen for delivery to the nasal mask, face mask, or nasal cannula.

  • GAS DEMAND DEVICE, METHOD OF INSTALLATION, GAS DELIVERY SYSTEM, AND METHOD OF USE
    Publication number: 20170065790
    Abstract: A gas demand device includes a primary chamber, a slave chamber, a secondary slave chamber, a timing gas flow path and a demand gas flow path all formed in a main body. The device cycles through five successive phases of operation in which: 1) a main diaphragm and a slave diaphragm are closed to disallow gas to flow through the timing gas and demand gas flow paths, 2) a main diaphragm is open while a slave diaphragm is closed to allow gas to flow through the timing gas flow path and disallow gas to flow through the demand gas flow path, 3) the main and slave diaphragms are open to allow gas to flow through the timing gas and demand gas flow paths, 4) the main diaphragm is closed while the slave diaphragm is open to disallow gas to flow through the timing gas flow path and allow gas to flow through the demand gas flow path, and 5) the main and slave diaphragms are closed to disallow gas to flow through the timing gas and demand gas flow paths.

  • DEMAND PNEUMATIC EMERGENCY OXYGEN SYSTEM
    Publication number: 20150040906
    Abstract: A valve, fitting with a conventional aircraft passenger emergency mask, for controlling gas flow to a passenger emergency mask, has a housing including a gas intake portion, an intermediate portion, and a gas outlet portion; a movable valve stem between the intake and intermediate portions; a spring biasing the stem towards the closed position; with the outlet portion having a planar exterior surface with a gas outlet opening located therein
