US 2012/0238997 A1 · SYSTEM AND METHOD FOR CONTROLLING ADMINISTRATION OF MEDICAL FLUID

Abstract

A system for controlling administration of medical fluid includes a fluid passageway to which is attached a first flow regulator, a second flow regulator, and a flow detector. The system also includes a controller for controlling the first and second flow regulators in response to a measurement taken by the flow detector of fluid movement in the fluid passageway. The first flow regulator, such as a pump, is configured to maintain fluid movement at flow values greater than an unrestricted flow value. The second flow regulator, such as a variable adjustable valve, is configured to maintain fluid movement at a flow value less than the unrestricted flow value. A method of controlling administration of medical fluid includes obtaining a target flow value, moving fluid through the disposable assembly, taking a measurement of fluid movement in the disposable assembly, and actuating a flow regulating apparatus.

Dependent claims

A fluid control system for controlling administration of fluid from a medicament container, the system comprising:

a fluid passageway comprising an inlet, an outlet, and an internal volume through which unrestricted movement of fluid corresponds to an unrestricted flow value;
a first flow regulator attached to the fluid passageway and configured to keep fluid movement in the fluid passageway at a flow value greater than the unrestricted flow value;
a second flow regulator attached to the fluid passageway and configured to keep the fluid movement in the fluid passageway at a flow value less than the unrestricted flow value;
a flow detector attached to the fluid passageway and configured take a measurement of the fluid movement in the fluid passageway;
and
a controller removably attached to the fluid passageway and coupled to the flow detector, the first flow regulator, and the second flow regulator, the controller configured to control the first and second flow regulators in response to the measurement by the flow detector.
