An interlock, latching and retaining mechanism for use in an infusion system, embodying a latch arm mounted to a rotatable shaft having a plurality of cams and gears attached thereto, a rectangular faceplate with a plurality of apertures formed therethrough, and a clamp. Rotating the latch arm functions to engage fluid monitoring, flow control and pumping structure of the infusion system with a pumping segment for control of fluid flow through the segment and also causes the clamp to hold the pumping segment in a required position. In another aspect, rotation of the latch arm additionally causes an air-in-line sensor to rotate into position on the pumping segment.

Interlock, latching, and retaining mechanism for an infusion pump

An engineered pumping segment for facilitating efficient and accurate peristaltic pumping of fluids, providing regulation of fluid flow and providing an effective interface for sensing fluid line pressure in a peristaltic pump system. The engineered pumping segment includes an elastomeric membrane sandwiched between a rigid base and a rigid cover and a slider adapted to slidably mount about the base and cover. The membrane and base define a channel for fluid flow and the membrane, base and cover cooperate to facilitate peristaltic pumping of fluids through the engineered pumping segment and to provide a pressure sensing interface, and in combination with the slider, cooperate to regulate fluid flow.

A trash collection and compacting apparatus primarily intended for use onboard an aircraft comprising a stationary compactor unit and interrelated movable trolley unit, the trolley unit having a plurality of separate trash collection chambers into which trash is deposited and compacted. The trolley unit includes wheels for moving the trolley through an aircraft for the collection of trash, and support rails for supporting the trolley unit on the compactor unit for the direct compaction of trash in the trolley. The compactor unit includes a compaction ram mounted on a carriage assembly for movement into discrete positions overlying each collection chamber of the trolley unit, and supports the trolley so that compaction forces are not transmitted to the aircraft. The trolley unit includes separable sides and dividing panels which facilitate the removal of compacted trash within the chambers, and has multiple fail safe locks and latches to ensure that the sides and panels are not inadvertently separated during trash collection and compaction. The trolley unit is also provided with fire doors to close the chambers, and removable trash bins are disposed in each trash chamber to facilitate handling of compacted trash, the bins having separable sides for emptying the compacted trash therefrom.
