Title (EN) CONTACT FREE ABSOLUTE POSITION DETERMINATION OF A MOVING ELEMENT IN A MEDICATION DELIVERY DEVICE
(FR) DÉTERMINATION DE POSITION ABSOLUE SANS CONTACT D'UN ÉLÉMENT MOBILE DANS UN DISPOSITIF D'APPORT DE MÉDICAMENT
Abstract:
(EN) The present invention relates to a medication delivery device for expelling set doses of medicament, the medication delivery device comprising a position determining assembly for detecting absolute positions of a rotatably mounted member arranged within the device, the position determining assembly comprising a plurality of transmitter electrodes arranged on a first exterior surface part of the rotatably mounted member, a plurality of receiver electrodes arranged on a second exterior surface part of the rotatably mounted member. A number of transmitter electrodes form pairs of interconnected electrodes with a number of receiver electrodes. A reading assembly fixedly arranged relative to for example the housing of the medication delivery device is also provided. The reading assembly comprises a plurality of transmitters arranged to electrically couple to one or more receiver electrodes, the reading assembly further comprising a plurality of receivers arranged to electrically couple to one or more transmitter electrodes.
(FR) La présente invention concerne un dispositif d'apport de médicament destiné à expulser des doses fixées de médicament, ce dispositif d'apport de médicament comprenant un ensemble de détermination de position permettant de détecter des positions absolues d'un élément monté rotatif agencé à l'intérieur du dispositif. L'ensemble de détermination de position comprend une pluralité d'électrodes d'émetteur agencées sur une première partie de surface extérieure de l'élément monté rotatif, une pluralité d'électrodes de récepteur agencées sur une seconde partie de surface extérieure de l'élément monté rotatif. Un certain nombre d'électrodes d'émetteur forment des paires d'électrodes interconnectées avec un certain nombre d'électrodes de récepteur. Un ensemble de lecture agencé de manière fixe par rapport au boîtier du dispositif d'apport de médicament par exemple est également prévu. Cet ensemble de lecture comprend une pluralité d'émetteurs agencés de façon à se connecter électriquement avec une ou plusieurs électrodes, cet ensemble de lecture comprenant aussi une pluralité de récepteurs agencés de façon à se connecter électriquement avec une ou plusieurs électrodes d'émetteur.
