Embodiment Construction

[0057] exist figure 1 In , an exemplary embodiment of an oxygen separator 10 for generating oxygen is schematically shown. The oxygen separator 10 may be used to generate oxygen for therapeutic applications, for example in the field of COPD treatment. The oxygen separator 10 may be designed as a fixed arrangement, eg for use in a hospital, or it may be a portable device, eg for use in home care applications. However, the oxygen separator 10 may also be used in any application where pure or substantially pure oxygen must be provided, such as in aircraft or for welding purposes. Such an oxygen concentrator or oxygen separator 10 may accordingly be an oxygen concentrator according to, for example, the type known as SimplyGo and commercially available from Philips Respironics.

[0058] according to figure 1 The oxygen separator 10 includes at least one oxygen separation device 12 capable of separating oxygen from an oxygen-containing gas. However, it is preferred that the oxyg...

Abstract

The invention relates to an oxygen separator (10), comprising at least one oxygen separation device (12, 14) comprising an oxygen separation sorbent (16, 18) for separating oxygen from an oxygen comprising gas, wherein the oxygen separation device (12, 14) comprises a gas inlet (24, 28) at a primary side being connected to an inlet conduct (20) for guiding a flow of oxygen comprising gas into the oxygen separation device (12, 14) and having a gas outlet (34, 36) at a secondary side being connected to an outlet conduct (30, 32) for guiding a flow of oxygen enriched gas out of the oxygen separation device (12, 14), wherein the secondary side of the oxygen separation device (12, 14) is further connected to a source of purging gas for guiding purging gas through the oxygen separation device (12, 14) and wherein the primary side of the oxygen separation device (12, 14) is connected to an exhaust conduct (70, 72) for guiding exhaust gas out of the oxygen separator (10), wherein the oxygen separator (10) further comprises a pressure adjusting device (40) for creating a pressure difference between the primary side and the secondary side of the oxygen separation device (12, 14), and wherein a gas sensor (82) is provided in the exhaust conduct (70, 72, 73) for determining the concentration of at least one component of the exhaust gas. Such an oxygen separator (10) provides an improved controlling behavior. The invention further relates to a method of generating oxygen from an oxygen comprising gas.

Description

technical field [0001] The present invention relates to the field of oxygen separation. More specifically, the present invention relates to oxygen separation using pressure swing adsorption for therapeutic applications, especially in the field of home care. Background technique [0002] Oxygen therapy is the administration of oxygen as a form of treatment. It is widely used for various purposes in chronic and acute patient care because oxygen is essential for cellular metabolism and in turn tissue oxygenation is essential for all physiological functions. Oxygen therapy should be used to benefit the patient by increasing the supply of oxygen to the lungs, thereby increasing the availability of oxygen to body tissues, especially when the patient is suffering from hypoxia and / or hypoxemia. Oxygen therapy can be used in both hospital and home care applications. A major home care application of oxygen therapy is for patients with severe chronic obstructive pulmonary disease (C...
