Display for an electrotransport delivery device
First Claim
1. A method of displaying how many events have occurred over a period of use of a patient-worn electrotransport delivery device by means of a delivery device display having on and off states, comprising:
- counting the number of events which occur over the period of use and storing the count; and
displaying the count by cycling the display between on and off states according to a predetermined regimen which correlates the number of on/off cycles to the count.

Abstract
An electrotransport delivery device (10) with a display (14) having only on and off states, and a method of operating the display (14), are provided. Preferably, the display 14 is a light (e.g., a light emitting diode) with lit and unlit states or an audible alarm (e.g., a beeper) with sounding and silent states. The device (10) counts and stores the number of events (e.g., patient initiated drug delivery or sensed patient condition) which occur over a predetermined period of time (e.g., the period of time over which the device is worn by the patient). The event count is displayed by cycling the display (14) between on and off states according to a predetermined regimen which correlates the number of on/off cycles to the number of events. The device and method permit the use of a simple and inexpensive means (e.g., an LED) to display (e.g., to a medical technician) the number of e.g., patient initiated doses delivered over a previous period of therapy.

17. A patient-worn electrotransport delivery device, comprising:
-
a counter for counting the number of events which have occurred over a period of use and storing the count; and a display having on and off states, the display being operative to cycle between on and off states according to a predetermined regimen which correlates the number of on/off cycles to the count. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
