Abstract: The volume of fluid removed from a patient during ultrafiltration is controlled automatically on the basis of central venous pressure (CVP) measurements. In one embodiment, a central venous catheter (CVC) is used for accessing blood during dialysis. A sensor located at the tip of the catheter or inside the dialysis machine is used to periodically measure CVP. CVP feedback data helps prevent the excessive removal of fluids from the patient.

Abstract: Volumetric accuracy in hemodialysis systems is provided by swapping pumps between the replacement fluid side and the output side for a hemofiltration system and between the return fluid side and the sorbent side for a closed-loop, sorbent-based system, such that same quantity of fluid is pumped at each point after the end of an even number of pump swaps. A method for calculating the time interval between swaps is provided based on an allowable difference in amount pumped in the two functions at any given time. A mechanism is provided for compensating for the differences in head pressure presented to the pumps for fluid coming from the replacement-fluid containers or the reservoir and that coming back from the patient through the dialyzer. The pump-swapping system provides an accurate means that can be inexpensively implemented, including using a disposable device.

Abstract: A flow management system for extracorporeal blood treatment application helps to ensure proper balance of incoming and outgoing fluids by precise balancing of relatively small balance chambers. The invention employs combinations of features that help to ensure accuracy including underfilling of the waste flow side of a fixed volume chamber and mechanical connections to synchronize valves and pumps.

Abstract: A hemofiltration machine at a local treatment site is linked to a remote main data base server by a local transmitting/receiving device. The machine acts as a satellite of the main data base server. The machine performs specified therapy tasks while monitoring basic safety functions and providing the person at the treatment location notice of safety alarm conditions for resolution. Otherwise, the machine transmits procedure data to the main data base server. The main data base server relieves the machine from major data processing tasks and related complexity. The main data base server, remote from the machine, controls the processing and distribution of the data, including the flow of information and data to the person undergoing therapy.

Abstract: A flow management system comprising a first panel having a fluid pathway and a second panel having a fluid pathway for passing a second fluid. The fluid pathway of the first panel passes a first fluid. The first panel includes a first compartment to receive a volume of the first fluid. The second panel includes a second compartment to receive a volume of the second fluid. The first and second panels are aligned so that the first compartment overlays the second compartment. The flow management system may be placed within a gap defined by a first surface and a second surface. The first and second compartments are disposed within the gap so that the second compartment bears against the second surface as the second fluid fills the second compartment and forces the first fluid out from the first compartment as the first compartment bears against the first surface.
