Abstract

This invention relates to a compliance monitor for monitoring patient usage of a medicament delivery device, where the medicament delivery device includes a store of medicament and an actuator. The compliance monitor includes a housing adapted to enclose the medicament delivery device, and a dose counter, associated with the housing, for recording the delivery of a dose of medicament to the patient from the medicament delivery device. The arrangement and construction is such that the housing is loosely coupled to the medicament delivery device, whereby the housing is able to move relative to the medicament delivery device during the delivery of the dose of medicament, and it is this movement which actuates the dose counter, either directly or indirectly, in order to record the delivery of the dose of medicament.
