摘要：
The present disclosure relates to a dose detection system for use with amedication delivery device in which a dose settingmember rotates relative to an actuator during dose delivery. The dosedetection system includes a module which is removably attachedto the medication delivery device. The module includes a rotation sensorattached to the actuator during dose delivery. A sensed elementis attached to the dose setting member and includes surface featuresdetectable by the rotation sensor. The rotation sensor comprisesa following member including a contact portion resting against and spring-biased in the direction of the surface features. The contactsurface is positioned to move over the surface features during rotation of thesensed element, and the rotation sensor is responsive tothe movement of the contact portion over the surface features to detect therotation of the dose setting member.
