Abstract

Embodiments of oxygen concentrators having a sieve bed that includes a vessel filled with a separation medium are disclosed. The sieve bed vessel at least partially supports one chassis component of the oxygen concentrator with respect to another chassis component. of the oxygen concentrator.

Claims (11)

1. A method of assembling a concentrator for providing a breathing gas comprising:

positioning a first portion of a sieve bed vessel in a pocket of a first chassis component to couple the sieve bed vessel to the first chassis component;

assembling a rim of the sieve bed vessel in a recess defined by the second chassis component to couple the sieve bed vessel to the second chassis component, wherein the sieve bed vessel supports the second chassis component relative to the first chassis component.

2. The method of claim 1 further comprising assembling said rim of the sieve bed vessel in a recess of a third chassis component to couple the sieve bed to the third chassis component.

3. The method of claim 1 further comprising securing the first chassis component to the second chassis component such that the sieve bed vessel is captured between the first chassis component and the second chassis component and supports the first chassis component with respect to the second chassis component.

4. The method of claim 2 wherein the first chassis component, the second chassis component, and the third chassis component are secured together, such that the sieve bed vessel is captured between the first chassis component and the second chassis component and supports the second and third chassis components with respect to the first chassis component.

5. A method of assembling a concentrator for providing a breathing gas comprising:

positioning a first portion of a sieve bed vessel in a pocket of a chassis base to couple the sieve bed vessel to the chassis base;

assembling a rim of the sieve bed vessel in a recess of a chassis cover to couple the sieve bed vessel to the chassis cover, wherein the sieve bed vessel supports the chassis cover relative to the chassis base component.

6. The method of claim 5 further comprising said rim of the sieve bed in a recess of a control panel to couple the control panel to the cylindrical vessel.

7. The method of claim 5 further comprising securing the chassis base and a chassis cover component together, such that the vessel is captured between the chassis base component and the chassis cover and the vessel supports the chassis cover with respect to the chassis base.
