Abstract: Disclosed herein is an identification system for an infusion set when the infusion set is installed in a pump. The identification system includes a pump, at least one sensor, a catheter, a tube and an alarm. The pump includes at least one sensor disposed thereon, which is in communication with the alarm. The catheter includes a distal end adapted for insertion into a body, and a proximal end opposite the distal end. The tube is operatively configured at a first end to removeably attach to the proximal end of the catheter, and the tube further includes a second end proximate to the sensor(s) on the pump. The sensor(s) are operatively configured to receive a signal generated at the first end or along a length of the tube, and to trigger the alarm upon receiving the signal so as to identify the corresponding pump.

Abstract: A housing assembly is provided, and includes a circuit board, a housing, and a clip. The circuit board has a main body and a ground plane. The main body defines an opening therethrough in the circuit board. The housing receives the circuit board. The clip for secures the circuit board to the housing. The clip includes a projecting tab and a flange. The projecting tab is received by the opening in the circuit board and the flange contacts the ground plane.

Abstract: A peristaltic pump assembly includes a pump body including a mounting pin coupled thereto. A removable cassette is slidably received on the mounting pin and is secured to the pump body via a retaining feature. The mounting pin is also configured to allow the removable cassette to rotate into and/or out of an installed position, or to position(s) therebetween.

Abstract: A peristaltic pump assembly includes a pump body and a cassette removably attached thereto, wherein the cassette includes a race configured to provide a compression surface for a tube supported by the cassette. A roller assembly is operatively connected to the pump body, wherein the roller assembly includes a plurality of rollers configured to apply a predetermined force to the tube, thereby compressing the tube against the race. The peristaltic pump assembly further includes a regulator disposed in the pump body and operatively connected to the cassette, where the regulator is configured to regulate the predetermined force applied to the tube.

Abstract: A radially compliant scroll compressor includes a fixed scroll, an orbiting scroll operatively connected to the fixed scroll, a synchronizer and at least one linkage member operatively connected to the orbiting scroll and the synchronizer. The at least one linkage member includes an orbiting crank handle operatively disposed on the linkage member, a crankpin operatively disposed through said synchronizer and extending into the crank handle and a damping member disposed on the crankpin between the synchronizer and the crank handle.

Abstract: A removable cassette for a peristaltic pump includes a cassette body and an occluder disposed at least partially in the cassette body and configured to be movable between an occluding position and a non-occluding position. The occluder includes an occluder body and an anti-ejection member integrally formed on the occluder body. The anti-ejection member is configured to substantially prevent the removal of the cassette from the peristaltic pump when the occluder is in the non-occluding position.

Abstract: A method of removing water from an inlet region of an oxygen generating system is disclosed herein. The method includes condensing, in an inlet region of the oxygen generating system, at least a portion of water vapor from a feed gas to water, and removing the water from the oxygen generating system prior to introducing the then-at least partially dehumidified feed gas to at least one sieve bed operatively disposed in the oxygen generating system.

Abstract: A peristaltic pump assembly includes a cassette configured to be operatively engaged with a pump housing. A roller assembly is operatively disposed within a cavity formed into the cassette. The roller assembly includes a plurality of rollers that may be arranged in a planetary configuration around a drive shaft. At least one guide element is disposed about the periphery of the roller assembly and in engagement with at least a portion of an outer surface of each of the plurality of rollers. The guide element is configured to guide the plurality of rollers when the plurality of rollers is rotating.

Abstract: A guide element for a peristaltic pump includes a base and a plurality of spindles established on a surface of the base.
