Cylinder Filling Oxygen Concentrator
View pageUS Patent:
7550031, Jun 23, 2009
Filed:
Oct 18, 2006
Appl. No.:
11/550442
Inventors:
Donald W. Hunter - Somerset PA, US

US Classification:
95130, 95121, 96127, 96128, 96130, 12820418, 417 62, 4171991
Abstract:
An energy efficient oxygen concentrator for filling high pressure portable cylinders with medical oxygen for use by ambulatory patients. Two compressors provide two pressurized air sources, one for operating an oxygen concentrator to provide a stream of oxygen enriched gas, and the other for driving a pressure intensifier for filling portable oxygen cylinders. Pressurized exhaust from the pressure intensifier is returned to the inlet side of at least one of the compressors for reducing the energy required to drive the compressor. Preferably, each compressor has a single reciprocating piston, a single motor drives both pistons and the pressurized exhaust from pressure intensifier is provided to the inlets for both compressors.

Appl. No.:
11/525443
Inventors:
Karl S. Bowser - Friedens PA, US
Frank Frola - Somerset PA, US
Frank Frola - Somerset PA, US
Assignee:
Sunrise Medical HHG Inc. - Longmont CO
International Classification:
F16K 51/00
US Classification:
251117, 2511491, 13760118
Abstract:
A coupling having, among other things, a body including a valve movable from a first position to a second position. The valve has an oxygen passageway in communication with a first inlet for a flow of oxygen to the oxygen passageway when the valve is in the first position. The valve has a second inlet for a flow of oxygen to the oxygen passageway when the valve is in the second position.
Cylinder Filler For Use With An Oxygen Concentrator

Filed:
Dec 22, 1999
Appl. No.:

Assignee:

International Classification:
B65B 3100
US Classification:
53403
Abstract:
An oxygen concentrator for supplying supplemental oxygen to a patient. The oxygen concentrator is adapted to supply supplemental oxygen directly to the patient and/or to a cylinder filler which is controlled to automatically fill a portable oxygen cylinder for use by an ambulatory patient. The cylinder filler is controlled to check the initial gas pressure in the cylinder prior to filling. If the initial cylinder pressure is below a preset minimum pressure, the cylinder filler will not fill the cylinder so that an empty cylinder which may be contaminated cannot be filled.
