| 摘要 |
A device for use in assessing a flow condition of a fluid is provided. The device comprises at least one electrochemical cell (102), comprising a working electrode (104) and at least one other electrode (106), sufficient for communication with the fluid. The fluid comprises a component sufficient to affect a mass-transport limited electrochemical reaction at the working electrode (104). The device also comprises at least one microcontroller operably connected to the at least one electrochemical cell (102) for providing a potential or a current to the working electrode (104) 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.
