Patent ID: 8348904

Claim:
A medical delivery system comprising: a container adapted to contain a medicament in a reservoir and to contain a slideably arranged piston which is moveable along a first axis in a distal direction towards an outlet of the reservoir so as to reduce the volume of the reservoir and expel the medicament through the outlet, the container further comprising a first protrusion, the location of the first protrusion representing at least one parameter associated with the container, a dosing assembly adapted to be secured to the container so as to allow driving means of the dosing assembly to move the piston of the container in the distal direction, the dosing assembly further having electric circuitry configured for identifying the location of the first protrusion on the container, wherein the medical delivery system comprises a first electric resistive track disposed in the dosing assembly, and, in use, a first wiper slideably engaging said first electric resistive track, the first wiper being associated with said first protrusion when the container is secured to the dosing assembly, the first electric resistive track and the first wiper being coupled to the electric circuitry so as to detect the relative position of the first wiper with respect to the first electric resistive track to thereby identify said container.
