APPARATUS FOR DETECTING ACTIVATION OF A DRUG DELIVERY DEVICE

Abstract:

An apparatus for detecting activation of a drug delivery device using a passive sensor. The passive sensor is configured to detect vibration of a drug delivery device caused by programming of a dose of medicament into the drug delivery device. The apparatus uses an output signal generated by the passive sensor in response to the vibration to provide a wake-up input signal to an electronic dose monitoring unit for monitoring the drug delivery device.
