Method for performing renal replacement therapy including producing sterile replacement fluid in a renal replacement therapy unit

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.
