<p>PCT No. PCT/SE89/00162 Sec. 371 Date Sep. 21, 1990 Sec. 102(e) Date Sep. 21, 1990 PCT Filed Mar. 29, 1989 PCT Pub. No. WO89/09042 PCT Pub. Date Oct. 5, 1989.A device for signalling the ingestion of medicaments in tablet form packed in blister packs in which the various tablet compartments on one side are delimited by a metal foil sheet which is common to the pack as a whole. A sheet (12) of insulating material has provided therein holes (20) which are so arranged as to correspond to the positions of the tablets in the pack. Electrodes (10, 11) having an electrically conductive surface are disposed circumferentially around each hole on one side of the sheet. A first number (10) of these electrodes is mutually connected to a first signal conductor, and a second number of these electrodes is mutually connected to a second signal conductor. The foil (2) is arranged such that when a tablet is removed through a hole in the blister pack located in the device, an electric contact is made between an electrode of the first number of electrodes (10) and an electrode of the second number of electrodes (11) and therewith an electric connection is established between the first and the second signal conductors. The first conductors from all of the first number of electrodes (10) are mutually connected to a common first signal conductor (100), and the second signal conductors (110, 111, 112) are each connected to a respective input of a sensing circuit (FIG. 6).</p> |
