    摘要: A drug delivery device comprises a body component located concentrically within a sleeve, wherein the body component comprises body component thread features and the sleeve comprises sleeve thread features that engage with the body component thread features such that the body component is caused to rotate within the sleeve as the body component and the sleeve component move axially with respect to one another by force of an engaging face of the sleeve thread features against an engaging face of the body component thread features causing sliding of the engaging face of the sleeve thread features over the engaging face of the body component thread features. One of the body component and the sleeve constitutes a first part and the other of the body component and the sleeve constitutes a second part. A conductive track pattern is formed on the thread features of the first part and plural contacts are formed on the second part such as to contact the conductive track pattern as the body component rotates within the sleeve.

    摘要: A supplemental device for attachment to an injection device, the supplemental device having a housing containing at least two electromechanical switches each having an open state and a closed state and a protrusion associated with each switch configured to protrude from the housing so as to contact a rotatable surface of the injection device while the supplemental device is attached to the injection device; and a processor arrangement configured to detect a change in the state of each of the switches; and to determine a direction of rotation of the rotatable surface of the injection device from the detected state changes.
