摘要： The haemodialyser proposed includes a vessel (1) designed to hold the dialysis liquid, a dialysis unit (2) and a double-hose pump (3). The vessel (1) is divided into two chambers (15, 16) of variable volume by a flexible partition (13). The fresh dialysis liquid is sucked out of one chamber (15) of the vessel into the dialysis unit, and the used dialysis liquid is passed back into the other chamber (16). The used dialysis liquid and the fresh dialysis liquid do not mix in the vessel (1). The flexible partition is formed by a plastic bag (13), suspended in the vessel, which lies tightly against the wall of the vessel (1) when the vessel fills with dialysis liquid. The cross-sectional areas of the two hoses of the double-hose pump are such that the ratio of the amount of blood flowing through the dialysis unit to the amount of the dialysis liquid is about 2:3. This ensures optimum removal of dissolved substances by a limited amount of dialysis liquid. The haemodialysis equipment proposed represents a system which can be produced using simple techniques and ensures optimun utilization of the dialysis liquid.

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： Automated control mechanisms and methods for controlling fluid flow in a hemodialysis apparatus are described. The methods can involve a controller receiving information from a pressure sensor in a control chamber of a reciprocating diaphragm-based blood pump and causing the application of a time-varying pressure waveform on a diaphragm of the blood pump during a fill-stroke of the blood pump. The controller can be configured and programmed to monitor a pressure variation in the control chamber measured by the pressure sensor and to compare the measured pressure variation to a pre-determined value. Based on such comparison, the controller can initiate a procedure to pause or stop a dialysate pump of the hemodialysis apparatus if the magnitude of the measured pressure variation deviates from the pre-determined value.

摘要： An enclosure for containing a portable hemodialysis unit includes a housing suitable to support components for performing hemodialysis including a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer. The housing may have a front panel at which blood circuit connections and dialysate fluidic connections are located, e.g., blood line connections for patient blood access, connections for a reagent supply, dialyzer connections for both blood flow and dialysate, etc. The enclosure may also include a pair of vertical, side-by-side doors hingedly mounted to the housing. With the doors in the closed position, access to the patient access and dialysate fluidic connections may be blocked, and the doors may allow for the retention of heat in the housing suitable for disinfection during a disinfection cycle.

摘要： A pump cassette is disclosed. The pump cassette includes a housing having at least, one fluid inlet line and at least one fluid outlet line. The cassette also includes at least one reciprocating pressure displacement membrane pump within the housing. The pressure pump pumps a fluid from the fluid inlet line to the fluid outlet line. A hollow spike is also included on the housing as well as at least one metering pump The metering pump is fluidly connected to the hollow spike on the housing and to a metering pump fluid line. The metering pump fluid line is fluidly connected to the fluid outlet line.
