Device for detecting the operation of a dispenser and the dispenser
First Claim
1. Device for detecting the operation of a dispenser, particularly a dispenser for solid or liquid a medium container storing dischargeable medium, having a discharge means, whose operation leads to the discharge of medium and the discharge means being operated by a relative movement between an operating element and the medium container, wherein the operating element (14) contains a detecting device (20) for detecting operations which have taken place and which generates an electric counting signal for detecting operations which have taken place.

Abstract
The invention relates to a device for detecting the operation of a dispenser, particularly for solid or liquid media, preferably containing at least one pharmaceutical substance, as well as to a device for discharging such media.
The problem of the invention is to simplify the detection of operations and to necessitate a smaller number of precision components, whilst also ensuring that only complete operations of the operating element are detected. It is also necessary to ensure greater security against manipulations and permit a better representability of high numerical values.
According to the invention the operating element contains a detecting device, e.g. a sensor, for detecting operations of the operating element which have taken place. The detecting device generates a counting signal, which is used for detecting operations which have taken place.
