Abstract: A peristaltic pump is disclosed. The peristaltic pump comprises a plunger configured to engage with a tube; a spring configured to bias the plunger against the tube; a position sensor operatively coupled to the plunger; an inlet valve configured to impede fluid flow through the tube positioned upstream of the plunger; an outlet valve configured to impede fluid flow through the tube positioned downstream of the plunger; and at least one processor in operative communication with the position sensor. The position sensor is configured to determine a position of the plunger. The at least one processor is configured to monitor the position of the plunger when the inlet and outlet valves are closed and the plunger is being biased by the spring, and determine at least one of an occlusion, an air bubble, and a leak exists in accordance with the monitored position of the plunger.

Abstract: A sensor apparatus and sensor apparatus system for use in conjunction with a cassette, including a disposable or replaceable cassette (3900). In some embodiments, the cassette (3900) includes a thermal well (5100) for permitting the sensing of various properties of a subject media. The thermal well (5100) includes a hollow housing of a thermally conductive material. In other embodiments, the cassette (3900) includes sensor leads (6016) for sensing of various properties of a subject media. The thermal well (5100) has an inner surface shaped so as to form a mating relationship with a sensing probe. The mating thermally couples the inner surface with a sensing probe. In some embodiments, the thermal well is located on a disposable portion and the sensing probe on a reusable portion.

Abstract: A cardiopulmonary bypass system utilizing membrane-based reciprocating positive displacement blood pumps (8300,8400) ('pod pumps'). In one aspect, the pod pumps are constructed to provide reduced shear forces on the blood being pumped. In another aspect blood flow through the pod pumps can be controlled by a controller using information from pressure sensors in the control chamber of the pod pumps. In another aspect, the pod pumps are included on a disposable unit that can be received and held by a receptacle means on a base unit, the base unit also providing pressurized control fluid to the pod pumps on the disposable unit through the receptacle means.

Abstract: A peristaltic pump (3001), and related system method are provided. The peristaltic pump includes a housing having a first slot, a door (3021) pivotally coupled to the housing and having a platen configured to receive a tube (3210), the door configured to have a closed position and an open position (shown), wherein the door includes a second slot. The pump further includes a carrier, for containing a slide clamp (3200), having a pivot defining first (3040) and second (3045) portions pivotally coupled together. The first portion is slidingly disposed within the first slot of the housing, and the second portion is slidingly disposed within the second slot of door. The pump further comprises a lever handle pivotally coupled to the door and operatively coupled to the carrier. When the door is closed the lever handle is pivoted to engage with the door and housing to hold the door and housing in engagement. The lever may also provide a force on the platen to raise the platen and compress the tube (3210) between a plunger (3091) of the pump and the platen. When the lever is used to hold the door closed it also engages with the carrier to move the slide clamp so that fluid may flow through the tube. When the lever is released it also moves the slide clamp such that it clamps shut the tube and prevents flow through the tube.

Abstract: A peristaltic pump (719), and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams (720, 726), first and second pinch-valve cam followers, a plunger cam (722), a plunger-cam follower, a tube receiver, and a spring-biased plunger (723, 724, 725). The first and second pinch-valve cams (720, 726) are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam (722) is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube (728). The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube (728). In other embodiments the plunger may be pivotally mounted to the pump housing.

Abstract: A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user. A dynamic support apparatus for supporting the prosthetic arm apparatus has a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic support apparatus has a control system that is operably connected to the dynamic interface and controls the dynamic interface to change its geometry.
