摘要： A portable gas fractionalization apparatus that provides oxygen rich air to patients is provided. The apparatus is compact, lightweight, and low-noise. The components are assembled in a housing that is divided into two compartments. One compartment is maintained at a lower temperature than the other compartment. The lower temperature compartment is configured for mounting components that can be damaged by heat. The higher temperature compartment is configured for mounting heat generating components. An air stream is directed to flow from an ambient air inlet to an air outlet constantly so that there is always a fresh source of cooling air. The apparatus utilizes a PSA unit to produce an oxygen enriched product. The PSA unit incorporates a novel single ended column design in which all flow paths and valves can be co-located on a single integrated manifold. The apparatus also can be used in conjunction with a satellite conserver and a mobility cart.

摘要： The embodiments of the present tracheostomy valves include a flexible diaphragm abutting a rib shaped substantially as a flat plate. Opposite the rib, the diaphragm abuts a boss and forms an uninterrupted seal therewith. As the tracheostomized patient inhales, the diaphragm bends about the rib, interrupting the seal and allowing air to flow smoothly into the valve. The features of the various embodiments contribute to a positive seal at all times except during inhalation, and low resistance to airflow through the valve during inhalation.

摘要： An occlusion detection system detects an occlusion in a fluid path of an infusion pump. The infusion pump is for delivering fluid to a user. The infusion pump includes a housing, a motor, a reservoir, one or more drive train components, a sensor, and an electronics system. The motor is contained within the housing. The reservoir contains the fluid to be delivered. The one or more drive train components react to stimulus from the motor to force the fluid from the reservoir into the user. The sensor is positioned to measure a parameter associated with the motor or a drive train component, and the sensor produces three or more output levels across a range of measurements. The electronics system processes the senor output levels to declare when an occlusion exists.

摘要： Methods and apparatus for stacking predetermined sheets of various intermixed sizes in a stacking location by advancement of stacking devices into that location, selectively guide further sheets past the stacking location. That guiding of further sheets past the stacking location is mechanically slaved to the advancement of the stacking devices into the stacking location. Where the stacking devices are withdrawn from the stacking location preparatory to each stacking of a predetermined sheet, the guiding of that predetermined sheet into the stacking location is mechanically slaved to such withdrawal of the stacking devices. Where the sheets are stacked against a movable wall, an unobstructed space for receiving each sheet guided to the stacking location is permanently preserved between the movable wall and the withdrawn stacking devices.

摘要： An anatomical simulator useful in training proper tracheostomy and nasogastric tube placement and tracheostomy tube cuff inflation is disclosed. The simulator includes a simulated trachea and simulated esophagus separated by a simulated tracheoesophageal wall. The simulated wall is flexible, such that when a tracheostomy tube is positioned therein and a cuff thereon is overinflated, the wall extends outwardly in the direction of the simulated esophagus.

摘要： In a pump chassis (112), spring-loaded members (108a, 108b) engage a pumping cassette (114) to it in a predetermined position. The members each include pairs of latches (110a, 110b) that are each beveled to form a ramp so that the latches and associated members are forced outwardly to enable the pumping cassette to be seated within the pump chassis. The latches engage the pump cassette as it is seated, holding it securely. A release button (138) is attached to a spring-loaded shaft (144) that extends into the interior of the pump chassis. The shaft has a ramp formed on its inner end. When the user depresses the release button, the ramp rides under inwardly extending arms (162a, 162b) provided on the members, forcing the members and attached latches to move outwardly. As the members move outwardly, the pumping cassette is released and readily removed.

摘要： Sheet feeding systems provide a sheet receiving nip at a peripheral region of a rotary sheet transport and arrange sheets in a stack having a stack and formed by a bottom sheet and spaced from the nip by a distance shorter than the minimum length of any of the sheets. The stack is temporarily lifted from a stack rest, and the bottom sheet is removed therefrom. Sheet jams are prevented by advancing any bottom sheet to the rotary sheet transport in a plane intersecting that rotary sheet transport at a distance from the nip. Each bottom sheet is further advanced from that intersecting plane to the nip, and such advanced bottom sheet is engaged with the nip for transport away from the stack with the rotary sheet transport. The stack end is returned to the stack rest after said removal of a bottom sheet, and the temporary stack end lifting, sheet advancing, sheet engaging and stack end returning steps are repeated individually for further bottom sheets advanced from the stack end.

摘要： A drive connector for elastomerically coupling a drive shaft to a driven shaft. An elastomeric coupling includes openings on opposite ends that are generally “D”-shaped forming an interference fit with correspondingly shaped ends of the drive shaft and the driven shaft. A web extends transversely within the interior of the elastomeric coupling, limiting the distance that the drive shaft and driven shaft are inserted within the openings of the coupling. The coupling includes a rib that runs longitudinally along its outer length. A sleeve having a groove corresponding in size and shape to the rib is slipped over the coupling and is connected to the driven shaft. The sleeve includes a rigid interior element that is overmolded with an elastomeric material. A cam bearing is fitted over a cam surface on the sleeve and provides a force in one direction, urging a plunger to displace an elastomeric membrane in a pumping cassette, forcing medicinal fluid to flow through the pumping cassette. The elastomeric membrane provides the restoring force to the plunger, so that a loop formed on the upper portion of the plunger and disposed around the cam bearing does not receive any force from the cam bearing to move the plunger away from the pump cassette. The elastomeric coupling and sleeve form a relatively compact assembly for coupling the drive shaft to the driven shaft and accommodate minor misalignment between the center lines of the drive shaft and the driven shaft.
