US 7,029,456 B2 · Medical fluid therapy flow balancing and synchronization system

Abstract

Systems, apparatus and methods that allow external infusion, IV or administration pumps to be synchronized with the internal pumps for a medical fluid therapy machine are provided. The system reduces the time and effort needed to calculate, set-up, enter and maintain flowrates of various fluids, maintained internally or externally with respect to the medical fluid therapy machine. The system also automatically follows therapy requirements, for example, a requirement that one pump/fluid be running/flowing for another pump/fluid to be enabled to run/flow. The system further automatically adjusts for variations in flowrate of one fluid with respect to another. In short, the system provides a more “hands-off”, safe and effective method and apparatus for medical fluid therapy fluid delivery.

Dependent claims

A medical fluid flow system comprising:

a blood treatment machine, the machine including a blood cleaning device and an on-board pump connectable fluidly to a patient;
a controller that controls the flow of a first fluid to and from the on-board pump and the patient;
a second pump residing externally from the machine, the second pump configured and arranged to pump a second fluid in response to a signal sent by the controller;
and
an operator interface in communication with the controller, the interface operable to receive information inputted from an operator and communicate that information to the controller, wherein the controller controls the on-board and second pumps to pump the first and second fluids using the information.
