Abstract
A removable gas separation cartridge includes a housing having an inlet port, an outlet port, and a bed of adsorbent material. The cartridge is removable from an oxygen concentrator which separates oxygen from ambient air by using an absorption process.
Claims17
A cartridge configured for use with an oxygen concentrator and configured to be removable from the oxygen concentrator by movement in a first direction, the cartridge comprising:
- a first bed of adsorbent material disposed along a first axis, wherein the first axis is substantially parallel to the first direction;
- a second bed of adsorbent material disposed along a second axis spaced-apart from the first axis, wherein the second axis is substantially parallel to the first direction;
- a first port disposed along the first axis, the first port configured to receive fluid flowing to the first bed or to expel fluid flowing away from the first bed;
- a second port spaced-apart from the first axis and configured to receive fluid flowing to the first bed or to expel fluid flowing away from the first bed;
- a third port disposed along the second axis and configured to receive fluid flowing to the second bed or to expel fluid flowing away from the second bed;
- and
- a fourth port spaced-apart from the second axis and configured to receive fluid flowing to the second bed or to expel fluid flowing away from the second bed;
- wherein the first, second, third, and fourth ports are oriented in a second direction opposite the first direction;
- wherein:
- a first plane extends through the first and third ports,
- the first plane is substantially perpendicular to the first and second axes,
- a second plane extends through the second and fourth ports,
- the second plane is substantially perpendicular to the first and second axes,
- the first and second planes are spaced-apart from one another.
