Embodiment Construction

[0050] Figure 1A -3 shows a portable oxygen concentrator device 10 according to the principles of the present invention. Generally, the device 10 includes a plurality of sieve beds or tanks 12A, 12B, a compressor 14, a lower portion or an air header 16 defining a plurality of channels 62-68 therein, a storage tank or container 18, and a set of pipes for penetrating the air 16 inner passages 62-68 of one or more flow paths of the air regulating valve 20 and the upper part or the oxygen delivery header 102. The controller 22 is connected to the air regulating valve 20 and selectively opens and closes the air regulating valve to control the air flow through the air header 16 and thus through the sieve bed 12. The controller 22 is also connected to an input / output device 23, for example, the device is used to set working parameters, such as the oxygen flow rate of the equipment.

[0051] It should be noted that the air regulating valve is collectively represented by the reference nu...

Abstract

A compressor (14) suitable for use in a portable oxygen concentrator (10). In one exemplary embodiment, the compressor includes a crankshaft (49) rotatable about a central axis and a plurality of diaphragm assemblies (46) spaced apart around the central axis generally within a plane. The diaphragm assemblies include diaphragms (50) movably mounted to respective housings to at least partially define chambers. A plurality of rods (44) extend between respective diaphragms and the crankshaft. The rods are coupled to the crankshaft such that the rods are offset axially from one another along the central axis and are coupled to the diaphragms for cyclically increasing and decreasing pressure within the chambers as the crankshaft rotates about the central axis.

Description

[0001] Priority statement [0002] In accordance with the provisions of Section 119(e) of the United States Code, this application requires No. 60 / 788,916 filed on April 3, 2006, No. 60 / 744,164 filed on April 3, 2006, and No. 60 / 744,164 filed on April 3, 2006. Priority of the U.S. provisional application No. 60 / 744,197, No. 60 / 744,271 filed on April 4, 2006, and No. 60 / 744,272 filed on April 4, 2006. Technical field [0003] The present invention generally relates to a compressor, a portable oxygen concentrator including a compressor, and a method for making the compressor and using the compressor, for example, to compress the air drawn into the oxygen concentrator. At the same time, the present invention also relates to the manufacturing and use of the oxygen concentrator. method. Background technique [0004] Patients suffering from lung diseases often need to breathe oxygen to improve their comfort and / or quality of life. Fixed oxygen sources that can provide oxygen to patients...
