<p>An iontophoretic drug delivery device (2) including an improved controller (14) is disclosed. More specifically, the controller (14) includes a number of features including recording the number of uses and, after a predetermined number of uses, the controller (14) will no longer operate. Similarly, the controller (14) may include a microprocessor (54) which times a useful life of the controller. Once the timer measures an elapsed period of time, the controller will indicate that it is no longer useable and should be discarded. The microprocessor (54) of the controller (14) may also be used for storage of a unique serial number embedded in the read only memory (45) of the microprocessor (54) for traceability purposes. Additionally, the unique serial number may be used as a security measure to ensure that the correct controller (14) is used with the proper patch (12). The microprocessor of the controller may also be used to record a date, time and/or duration of usage and playback the recorded information to a health-care professional. In addition, the controller (14) and patch (12) include electronics which ensure compatibility of the reusable iontophoretic controller with the specific patch to which it is connected. If the controller (14) determines that the patch (12) is incompatible with the controller, the controller does not apply current to the patch.</p> |
