Abstract
The invention is concerned with testing of inhalers used for medicament delivery. Such devices are often intended to be first shaken by a user to prepare them, and then fired by operation of some mechanical mechanism. In order to automate testing, the invention provides a shake device having a carriage 14 for receiving and releasably mounting one or more inhalers. The carriage is mounted upon a guideway for linear movement upon it. A linear motor 26 is operatively coupled to the carriage to reciprocally drive it to shake the mounted inhaler(s). A system embodying the invention may further comprise a fire device having a movable firing member 54, 56 for engaging with an inhaler mounted in the carriage and actuating its firing mechanism.
