SYSTEM AND METHOD FOR CONTROLLING ADMINISTRATION OF MEDICAL FLUID
First Claim
1. A fluid assembly comprising:
- a fluid passageway comprising a primary inlet, a secondary inlet, and an outlet, wherein unrestricted movement of fluid through the fluid passageway corresponds to an unrestricted flow value;
a pump, connected between the primary inlet and the outlet, configured to permit a fluid movement through the fluid passageway and to operate when connected to a power source;
a valve connected between the pump and the outlet and configured to restrict the fluid movement through the fluid passageway; and
a flow detector connected between the pump and the valve and configured to measure the fluid movement.

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.
