Oxygen concentrator having structural sieve beds
View Patent ↗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.
1. A concentrator for providing a breathing gas comprising:
a base component that includes a sieve bed pocket;
a sieve bed comprising a cylindrical vessel filled with an oxygen separation medium, wherein a first end of the cylindrical vessel is disposed in said sieve bed pocket to couple the cylindrical vessel to the base component;
a cover component that includes at least one support flange that defines a recess, wherein a rim of said cylindrical vessel is disposed in the recess of the support flange to couple the cover to the cylindrical vessel.
2. The concentrator of claim 1 further comprising a control panel that includes a support flange that defines a recess, wherein said rim of the cylindrical vessel is disposed in the recess of control panel support flange to couple the control panel to the cylindrical vessel.
3. The concentrator of claim 1 wherein the rim comprises a radially extending projection.
4. The concentrator of claim 3 wherein the radially extending projection is disposed in said recess.
5. The concentrator of claim 4 wherein the recess is defined as a space between a pair of substantially horizontally extending walls.
6. The concentrator of claim 4 wherein the recess is defined as a space between a pair of walls that extend substantially parallel to a top plate of the cylindrical vessel.
7. The concentrator of claim 1 further comprising a second sieve bed coupled to the base component and the cover component.
8. The concentrator of claim 1 wherein the sieve bed pocket comprises bosses and walls that provide support for the first end of the sieve bed cylinder and limit lateral movement of said sieve bed cylinder with respect to the base component.
9. The concentrator of claim 1 wherein the base component and the cover component are secured together, such that the cylindrical vessel is captured between the base component and the cover component and the cylindrical vessel supports the cover component with respect to the base component.
10. The concentrator of claim 1 wherein the cylindrical vessel comprises a metal vessel.
11. The concentrator of claim 1 wherein the cylindrical vessel comprises an aluminum vessel.
