INJECTION MONITORING MODULE

Abstract

An injection monitoring module is adapted and configured to be removably mounted to an end of an injection pen having a body, a dose setting wheel connected thereto, and an injection activator. The dose setting wheel is rotatable about a central longitudinal axis of the pen injection system during dose setting and fixed against rotation during injection. The injection monitoring module comprises a hollow main body comprising a distal body portion, which extends around an outer surface of the injection pen body distally to the dose setting wheel, and the distal body portion comprises diameter altering means configured to dynamically alter an inner diameter of a central bore of the distal body portion from a first value to a second value different to the first value when mounting the injection monitoring module on the injection pen body.
