DEVICE FOR MEASURING THE OBSERVANCE OF MONITORING A MEDICAMENT IN BLISTERS

摘要

The monitoring device (1) comprises a platelet (2) with an electronic circuit (3) for detecting and recording an extraction movement of pills (4) belonging to a blister (5), and a unit (6) for fixing the blister to the platelet. The platelet is formed of a support comprising a conductor a circuit for forming interrupters that are opened when the pills are manually extracted by the user. The conductor comprises a printed yarn of a metal conductor, where the yarn comprises conductive portions along a conductive path. The monitoring device (1) comprises a platelet (2) with an electronic circuit (3) for detecting and recording an extraction movement of pills (4) belonging to a blister (5), and a unit (6) for fixing the blister to the platelet. The platelet is formed of a support comprising a conductor a circuit for forming interrupters that are opened when the pills are manually extracted by the user. The conductor comprises a printed yarn of a metal conductor, where the yarn comprises conductive portions along a conductive path. The conductive path is each time arranged for providing a high resistance along the parallel portion. The support is formed of a thin, flexible and foldable transparent plastic sheet. Frangible portions are regularly provided on sides to correspond to a pill. Four breakage points of the conductive portions are provided with the corresponding pill at the edge of frangible portion such that the frangible portion, the platelet and the point of breakage of the conductive portion are simultaneously broken when the pill is extracted. The electronic circuit comprises total impedance measuring unit of the conductive part for providing the extraction movement of the pill. The conductive portion forms a U shaped spring with a puller on an edge of the frangible portion. The breakage points are situated at a distance (1-3 mm) of the frangible portion outside the support, and are formed by two inlets at a level of the U shaped bar and other two at a level of top of the U branches. Openings are formed in U shaped branches having a diameter of 0.5-2 mm. Each frangible portion comprises a precut pellet defined by two banana-shaped symmetrical portions on ending located a distance from the periphery. The ends of symmetrical portions are prolonged by the drilling of several small tangential holes forming a pyramid or arc, whose apex is formed by a hole located between the two arms of the U. An intermediate layer comprising an adhesive insulating film is interposed between the crackable blister and the platelet around the peripheral edge of the frangible portion. The support includes a central recesses arranged in a diamond shape in center of each of four points for frangible portions to access these corners. The conductive portions are straight, and are formed by adhesion of two detachable legs connected between the yarn junctions via a central portion. The junction is broken by perforations connected to the platelet. A unit is arranged for periodically and/or constantly maintaining the impedance with a unit for comparison of first average voltage on 5-10 measurements.
