Abstract
A device detects the removal of drugs from a drug blister pack. The device contains a base for receiving the drug blister pack which has a base surface which is configured for contact with the electrically conducting, metal foil that closes the pockets. In the region of the pockets, the base has holes that are configured for the passage of the drugs present in the pocket. In the region of the holes one transmitting coil and at least two receiving coils are each arranged and extend around the respective hole. The receiving coils are associated with each other with respect to the transmitting coil and are arranged such that when the foil resting against the base in the region of the respective hole is undamaged the difference of the voltages induced in the receiving coils by an electric current in the transmitting coil lies below a predetermined threshold value.
