Abstract: Reciprocating positive-displacement membrane 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 are disclosed. The speed of a pump stroke can be adjusted by altering a frequency of pressure pulses delivered to the pump membrane during a fill stroke or a delivery stroke of the pump. A pumping algorithm may divide a pump stroke into an initial pumping period and a end-of-stroke pumping period, with the pressure pulse duration being longer during the initial pumping period. This arrangement may allow for a minimum pump flow rate while also providing a pressure ripple that can be used to detect the end of a pump stroke.

Abstract: Certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) are 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., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

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.
