DISPLAY FOR ELECTROTRANSPORT DELIVERY DEVICE

PROBLEM TO BE SOLVED: To provide an electrotransport drug delivery device which provides storage and display of prior events which have occurred over the course of therapy. SOLUTION: An electrotransport delivery device (10) with a display (14) having on and off states, and a method of operating the display, are provided. Preferably, the display 14 is a light with lit and unlit states or an audible alarm, e.g., a beeper, with sounding and silent states. The device counts and stores the number of events, e.g., patient initiated drug delivery, which occurs over a predetermined period of time over which the device is worn by the patient. The event count is displayed by cycling the display (14) between on/off cycles according to the number of events. The device and method permit the use of a simple and inexpensive means (e.g., an LED) to display to a medical technician the number of e.g., patient initiated doses delivered over a previous period of therapy.
