Ampoule recognition
First Claim
1. An ampoule for an injection or infusion apparatus, said ampoule comprising:
- a threaded surface parallel to a central longitudinal axis extending between a dispensing end and a distal end of said ampoule, said threaded surface providing a predetermined orientation of said ampoule when said threaded surface is engaged with an administering device, said distal end comprising a surface perpendicular to the axis;
at least four available predetermined recognition element positions positioned along a radius extending radially on the perpendicular surface about the longitudinal axis;
at least two recognition elements each positioned in one of the at least four predetermined recognition element positions;
wherein each of the predetermined recognition element positions is positioned asymetrically along the radius such that the circumferential distance between any two positions is different than the circumferential distance between any other two positions,wherein the number of available predetermined recognition element positions is greater than the number of recognition elements, andwherein the recognition elements are positioned in the predetermined element recognition positions such that detection of the positions of the recognition elements enables recognition of the ampoule.

Abstract
An ampoule for use with an administering device such as an injection or infusion apparatus, at least two recognition elements associated with the ampoule, each of which at least two recognition elements can be arranged in one of at least two predetermined positions relative to the ampoule, wherein the at least two predetermined positions are asymmetrically located relative to the ampoule, and an administering device such as an injection or infusion apparatus which can be coupled to the ampoule. In one embodiment, the administering device has at least two associated sensors at predetermined positions in order to recognize the arrangement of the at least two recognition elements associated with an ampoule and, in another embodiment, the administering device has at least one sensor which can be moved relative to an ampoule.
