  • Pneumatic manifold for a dialysis system
    Patent number: 11278654
    Abstract: The invention relates to a pneumatic manifold for controlling a fluid level in an arterial and/or venous drip chamber of a dialysis system. The pneumatic manifold includes pneumatic valves fluidly connected to conduits and one or more pumps. Selectively activating the pneumatic valves can result in pressure changes for raising or lowering a fluid level in the arterial and/or venous drip chambers.
    Type: Grant
    Filed: October 2, 2018
    Date of Patent: March 22, 2022
    Assignee: Medtronic, Inc.
    Inventors: Paul R. Chapman, Jr., William Hajko, Carl Wilbert Gomes, II
  • Sorbent manifold for a dialysis system
    Patent number: 11033667
    Abstract: The present invention relates to a sorbent manifold and related systems and methods having a plurality of passageways fluidly connectable to one or more valves and one or more sensors and components for use in a sorbent dialysis system. The sorbent manifold can control the one or more valves to direct fluid to either pass through a sorbent cartridge or bypass the sorbent cartridge based on measurements obtained from sensors.

  • DIALYSIS SYSTEM OF INTEGRATED MANIFOLDS
    Publication number: 20190151527
    Abstract: The invention relates to a system of integrated manifolds for use in dialysis. The system of integrated manifolds can include two or more manifolds connected by fluid lines, the manifolds forming at least a portion of a dialysate flow path. In certain embodiments, valves, sensors, and/or pumps can be included. A controller can control the valves and pumps to pump fluid through the manifolds in a specified flow path.
