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.

Abstract: A device and method for displaying and metering a product to be administered from a reservoir by means of a dose metering device and a display unit, wherein a specific dose is set by moving the dose metering unit from an initial position in a metering direction across a dose metering distance. A reference point is defined by an initial position of the dose metering device in readiness for administering a first dose or a position assumed by the dose metering device after administering a dose. The dosage setting displayed by the display unit is a dosage value based on the distance travelled by the dose metering device from the reference point in the metering direction.
