    摘要: A method and device for renal replacement therapy is described that sterile-filters solution that can subsequently be used as a replacement fluid in the same unit. The devices and methods include a pump that can be reversed from its normal forward-pumping direction to sterilize a container of replacement fluid to produce sterile replacement fluid. The sterile replacement fluid is captured in a fluid bag. Upon sterilization of the contents of the container, the pump switches to run in its normal forward-pumping direction. The sterile replacement fluid produced by the previous process is now injected into a patient to perform renal replacement therapy. The waste produced during the renal replacement therapy can be trapped in the container that previously held the non-sterile solution. Systems for sterile filtration and subsequent renal replacement therapy that include pre-connected, sterilized, disposable kits for fluid management and batch collection of sterilized fluid are also described.

    摘要: A pressure measurement device usable for monitoring pressure of fluids such as blood, waste, and replacement fluid in a blood treatment system provides a reliable signal and other benefits by virtue of a number of features of the various embodiments disclosed. The pressure of fluid carried by a vessel or tube is measured by measuring a change in shape of the vessel or tube via a sensor element contacting it. Materials, shape, and mechanical support cooperatively ensure that the little inelastic strain occurs and pressure measurements are repeatable. The embodiments are compatible with the use of disposable vessels and tubes.

    摘要: Peritoneal dialysis is performed by circulating peritoneal dialysis solution through a peritoneal cavity by conveying peritoneal dialysis solution through an inlet branch into the peritoneal cavity and by withdrawing peritoneal dialysis solution through an outlet branch from the peritoneal cavity. Peritoneal dialysis solution in the outlet branch is conveyed along a first side of a porous membrane while conveying a regeneration solution containing at least one regenerating agent along a second side of the porous membrane. The membrane is configured to transport the regenerating agent into the peritoneal dialysis solution while transporting waste from the peritoneal dialysis solution into the regeneration solution, thereby creating a regenerated peritoneal dialysis solution. The regenerated peritoneal dialysis solution is circulated through the inlet branch into the peritoneal cavity.
