DETECTION OF PRESENCE AND ALIGNMENT OF A THERAPEUTIC AGENT IN AN IONTOPHORETIC DRUG DELIVERY DEVICE

摘要

A system is provided for testing whether an iontophoretic drug delivery device is in an appropriate state for administering a therapeutic agent into an animal body. An electrical characteristic of at least one electrical path associated with an electrode test point is used to determine whether the iontophoretic device is in an appropriate state. The measured electrical characteristic indicates that the iontophoretic device is in an appropriate state for administering the therapeutic agent into the animal body when the therapeutic agent is properly disposed with respect to the electrodes of the iontophoretic device.
