Abstract
The present invention relates to a cartridge or a cartridge holder adapted to be used in connection with handheld medication delivery devices. In particular, the present invention relates to intermediately positioned cartridges or cartridge holders providing at least one electrical connection between electronics of a medication delivery device and an injection needle attached to the medication delivery device. The electrical connection(s) between the electronics and the injection needle may be of galvanic or capacitive nature, the latter being provided via medicament contained in the cartridge.
Claims13
A cartridge holder adapted to form a lower part of a handheld medication delivery device when attached thereto, the cartridge holder comprising
- a body extending from a rear end to a needle receiving portion of the cartridge holder, wherein the rear end of the cartridge holder comprises one or more electrical contacts arranged to provide electrical contact to corresponding electrical contacts arranged on an associated upper part of the medication delivery device to which the rear end of the cartridge holder is adapted to be attached, and wherein the needle receiving portion is adapted to establish a galvanic or capacitive connection to an electrically conductive exterior surface part of an injection needle attached to the cartridge holder, and
- an electrically conductive element providing at least one electrical connection between the one or more electrical contacts at the rear end and the needle receiving portion,
- wherein the body of the cartridge holder comprises, between the rear end and the needle receiving portion, an exterior surface portion being galvanically isolated from the electrically conductive element and so disposed that the electrically conductive element is inaccessible from the exterior when the associated upper part of the medication delivery device and the injection needle are attached to the cartridge holder.
A cartridge for a medication delivery device, the cartridge being adapted to contain medicament to be expelled from said medication delivery device, the cartridge comprising a body having attachment means arranged on a rear end thereof for coupling the cartridge to the medication delivery device, said body extending from said rear end to a cartridge neck adapted to hold a septum piercable by an injection needle, wherein the body of the cartridge comprises an integrated electrically conductive element providing at least one electrical connection between the rear end of the cartridge and the cartridge neck, and wherein the body of the cartridge comprises, between the rear end and cartridge neck, an exterior surface portion being galvanically isolated from the electrically conductive element and so disposed that the electrically conductive element becomes inaccessible from the exterior when the cartridge forms part of a medication delivery device and when an injection needle pierces the septum.
