  • Publication number: 20090173682
    Abstract: An extracorporeal blood processing system comprises a plastic molded compact manifold that supports a plurality of molded blood and dialysate fluidic pathways along with a plurality of relevant sensors, valves and pumps. A disposable dialyzer is connected to the molded manifold to complete the blood circuit of the system. The compact manifold is also disposable in one embodiment and can be detachably installed in the dialysis machine. Two-way valves in the manifold are used to direct the dialysate flow to the dialyzer in hemodialysis mode of operation and to bypass the dialyzer to direct the flow of infusion grade dialysate directly to the patient in hemofiltration mode of operation.

  • Patent number: 7387210
    Abstract: A combined filter cartridge and manifold for use in a water purification system or the like, to facilitate substantially drip-free filter cartridge removal and replacement. The filter cartridge includes water inlet and outlet ports for respective connection with inlet and outlet fittings on the manifold. A pivoting manifold cap normally overlies and retains the filter cartridge in connected relation with the manifold fittings and a water supply coupled to the manifold. Pivoting movement of the manifold cap toward an open position shuts off the water supply and then permits filter cartridge separation from the manifold, with check valves at the manifold inlet/outlet fittings and cartridge inlet/outlet ports preventing significant water leakage.
