Abstract

A flow rate meter comprises a disposable fluid transport portion and a reusable interface connector removably attached to the transport portion. The transport portion includes a flow conduit having an input and an output, while the interface connector provides feedback to a desired location. First and second portions of control circuitry are, respectively, associated with the transport portion and the interface connector. The first circuitry portion includes a plurality of electrodes and derives flow rate. The device measures a range of flow rates and is adapted, for example, for use in micro-fluidic systems including fluids administration to a patient'"'"'s body.

Claims

1. A flow rate meter, comprising:

a. a disposable fluid transport device portion, including;

i. a flow conduit having an inlet and an outlet, said flow conduit defining a flow channel; and

ii. at least a first portion of a control circuitry which is operative to derive the flow rate, wherein said first portion includes a plurality of electrodes adapted to directly contact fluid when present within said conduit; and

b. a reusable interface connector removably attachable to said disposable fluid transport device portion, said reusable interface connector including;

i. a second portion of said control circuitry

ii. a communications interface for establishing feedback communication to a desired location.
