摘要： A double diaphragm slurry pump (7080) comprises: a pump body (8200) defining a vertical longitudinal axis (LA) and first (8201) and second (8202) pumping chambers; an inlet flow manifold (8203) and an outlet flow manifold (8204) coupled to the pump body; a first pump head (8230a) coupled to the body adjacent the first pumping chamber, the first pump head comprising a longitudinal flow bore (8231) separate from the first pumping chamber and fluidly coupled to the inlet and outlet flow manifolds, an upper air vent bore (8232), and a lower slurry exchange bore (8233), the upper air vent bore and lower slurry exchange bore each fluidly coupling the longitudinal flow bore in turn to the first pumping chamber; and an operating shaft (8240) coupled to a resiliently deformable diaphragm (8241) disposed in the first pumping chamber; wherein the shaft is moveable in a pump stroke to pump a fluid through the longitudinal bore of the first pump head and the first pumping chamber from the inlet flow manifold to the outlet flow manifold; and wherein the upper air vent bore (8232) is smaller in diameter than the lower slurry exchange bore (8233) such that air is preferentially ejected from the first pumping chamber rather than slurry during the pump stroke.

摘要： Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

摘要： A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

摘要： Illustrative embodiments of positive displacement pumps utilizing pressure compensating calibration, as well as related systems and methods, are disclosed. In one illustrative embodiment, a method of operating a positive displacement pump includes sensing, with a pressure sensor disposed at a fluid outlet of the positive displacement pump, a back pressure at the fluid outlet, transmitting a pressure signal associated with the sensed back pressure from the pressure sensor to a controller of the positive displacement pump, and identifying, on the controller, a volume of fluid pumped by the positive displacement pump using the pressure signal.

摘要： A novel changeover mechanism for a compressed air driven double diaphragm pump comprises a shaft slidably mounted through aligned apertures in opposing surfaces of the twin diaphragm chambers. At the center of the shaft between the two diaphragm chambers is provided an annular notch in to which is located an arm extending from a U shaped frame. The U shaped frame is pivotally mounted atop a valve plate which includes multiple ports. Positioned against a surface of the valve plate is a valve closure component which is configured to slide across the surface selectively obstructing the multiple ports. The valve closure component is held in place by a metal peg hingedly mounted in slots provided in parallel extension of the U shaped frame. Linear tension springs connect the hinged wire pusher with U shaped frame adjacent the pivot point. The springs bias the position of the valve closure component against the valve plate in an off center position.
