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.
Claims16
A portable oxygen concentrator, comprising:
- a separation cartridge selectively removable from a receptacle by movement relative to the receptacle in a first direction, the separation cartridge comprising an inlet oriented in a second direction opposite the first direction, an outlet oriented in the second direction, and a bed of adsorbent material configured to preferentially adsorb nitrogen;
- wherein a first line extending parallel to the first and second directions passes through the outlet,
- wherein a second line spaced-apart from the first line and extending parallel to the first line passes through the inlet, and
- wherein the separation cartridge is configured such that, when fluid flows through the separation cartridge, fluid flowing along the first line contacts the adsorbent material of the bed and fluid flowing along the second line does not contact the adsorbent material of the bed.

A separation cartridge for a portable oxygen concentrator, comprising:
- an inlet oriented in a direction;
- an outlet oriented in the direction;
- a bed of adsorbent material configured to preferentially adsorb nitrogen;
- and
- wherein a first line extending parallel to the direction passes through the outlet,
- wherein a second line spaced-apart from the first line and extending parallel to the first line passes through the inlet, and
- wherein the separation cartridge is configured such that, when fluid flows through the separation cartridge, fluid flowing along the first line contacts the adsorbent material of the bed and fluid flowing along the second line does not contact the adsorbent material of the bed.
4 more elements
A portable oxygen concentrator, comprising:
- a first bed of adsorbent material configured to preferentially adsorb nitrogen;
- a first inlet oriented in a direction, wherein the first inlet is configured to direct a flow of ambient air to the first bed;
- a first outlet oriented in the direction, wherein the first outlet is configured to expel product gas flowing downstream of the first bed;
- a second bed of adsorbent material configured to preferentially adsorb nitrogen;
- a second inlet oriented in the direction, wherein the second inlet is configured to direct a flow of ambient air to the second bed;
- a second outlet oriented in the direction, wherein the second outlet is configured to expel product gas flowing downstream of the second bed;
- a power pack removable from the portable oxygen concentrator;
- a pump electrically coupled to the power pack, the pump operable to cause a flow of fluid to move relative to the first and second beds of adsorbent material;
- a user interface configured to allow a patient to adjust and monitor operation of the portable oxygen concentrator;
- a carrying device for transporting the portable oxygen concentrator;
- wherein a first line extending parallel to the direction passes through the first outlet,
- wherein a second line spaced-apart from the first line and extending parallel to the first line passes through the first inlet,
- wherein the portable oxygen concentrator is configured such that, during use, fluid flowing along the first line contacts the adsorbent material of the first bed and fluid flowing along the second line does not contact the adsorbent material of the first bed,
- wherein a third line extending parallel to the direction passes through the second outlet,
- wherein a fourth line spaced-apart from the third line and extending parallel to the third line passes through the second inlet, and
- wherein the portable oxygen concentrator is configured such that, during use, fluid flowing along the third line contacts the adsorbent material of the second bed and fluid flowing along the fourth line does not contact the adsorbent material of the second bed.
