  • Apparatus for compressing and storing oxygen enriched gas
    Patent number: 7294170
    Abstract: An apparatus and process for supplying low pressure oxygen-enriched gas to a patient and at a moderate pressure to a radial compressor, whereupon it is compressed and fed to a high pressure storage tank. The oxygen-enriched gas is prioritized so that it is continuously supplied via a patient flow line to the patient.
    Type: Grant

    Date of Patent: November 13, 2007
    Assignee: Invacare Corporation
    Inventors: Joseph B. Richey, II, Gerald G. Goertzen
  • Oxygen conserving device utilizing a radial multi-stage compressor for high-pressure mobile storage
    Patent number: 7204249
    Abstract: An oxygen concentrator is utilized in combination with a compressor, preferably a radial compressor, to provide a highly enriched and compressed oxygen gas in a mobile container such as a gas cylinder. The combination and method of production provides for the facile preparation of an enriched source of oxygen for use by an ambulatory or wheelchair-confined patient. The oxygen concentrator utilizes two or more molecular sieves to provide a breathable gas of at least about 85% or 90% oxygen from atmospheric air. The oxygen-enriched gas can be stored in a buffer tank and prioritized so as to supply a patient with a proper amount and concentration of oxygen and secondarily to supply an amount of the enriched oxygen to a compressor. The radial compressor utilizes multiple stages to produce the highly compressed oxygen-enriched gas and has radially arranged pistons. The radial compressor is compact and lightweight.
