VIBRATION SENSOR BASED DRUG DELIVERY MONITOR
First Claim
1. A monitoring system for a device to be monitored, comprising:
- a vibration sensor that generates an electronic signal, wherein the sensor is selected from the list which consists of;
an accelerometer;
a vibration velocity sensor; and
a relative motion sensor;
wherein the monitoring system further comprises an electronic storage device holding stored electronic information corresponding to an expected sensor signal associated with a desired operation of the device to be monitored; and
a software program which identifies an event based an analysis of the measured electronic signals from the vibration sensor by comparing the analysis results with the stored electronic information,a display which displays information related to the identified event,a wireless data transmitter,wherein the device to be monitored is a drug delivery device.

Abstract
A monitoring system comprising a monitor is disclosed that utilizes a vibration sensor to monitor the occurrence and properties of an event. The monitor does not require disassembly of the device to be monitored, or interfere with the operation of the device to be monitored, because the monitor is affixed to the exterior of a device to be monitored or a component thereof, or is integrated into the design of the device to be monitored. In a preferred embodiment, the device to be monitored is a drug delivery device, most preferably an inhaler or autoinjector. The monitoring system includes a display device such as a smartphone or tablet computer for analyzing data related to the device to be monitored usage and displaying information to a user, patient and/or caregiver before, during, and after a usage event. Preferred embodiment monitor the inhalation flow rate through an inhaler, and the dose delivered by an injector.
