摘要：
A pen-type drug injection device comprises a body component (408) located concentrically within a sleeve (406), wherein both the body component and the sleeve comprise engaging thread features (432, 436) such that the body component is caused to rotate within the sleeve as the body component and the sleeve move axially with respect to one another by force of an engaging face of the sleeve thread features (436) against an engaging face of the body component thread features (432) 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 (300) is formed on the thread features of the first part and plural contacts (212) are formed on the second part such as to contact the conductive track pattern as the body component rotates within the sleeve to allow determination of the relative position of the sleeve and the body component - and thus the dose through detecting the conductive track pattern whilst providing relatively little additional resistance to axial movement.La présente invention concerne un dispositif dinjection de médicament de type stylo qui comprend un composant de corps (408) situé de façon concentrique dans un manchon (406), le composant de corps et le manchon comprenant des éléments de filetage dengagement (432, 436) de sorte que le composant de corps soit amené à tourner dans le manchon lorsque le composant de corps et le manchon se déplacent axialement lun par rapport à lautre par la force dune face dengagement des éléments de filetage de manchon (436) contre une face dengagement du composant déléments de filetage de corps (432) causant le coulissement de la face dengagement des éléments de filetage de manchon sur la face dengagement du composant des éléments de filetage de corps.
