Abstract
A device for use in assessing a flow condition of a fluid, or a fluid in a flow path, is provided. The device comprises at least one electrochemical cell, comprising a working electrode and at least one other electrode, sufficient for communication with the fluid, or sufficient for communication with a flow path, such that when sufficient fluid is in the flow path, the cell is in communication with the fluid. The fluid comprises a component sufficient to affect a mass-transport limited electrochemical reaction at the working electrode. The device also comprises at least one microcontroller operably connected to the at least one electrochemical cell for providing a potential or a current to the working electrode and for assessing the electrochemical reaction. A method of assessing a flow condition of a fluid, or a fluid in a flow path, is also provided. The device and the method of the present invention may be used in connection with the delivery of a fluid-borne or fluidized drug or medicament to a subject.
