CA 2739404

A linear capacitance displacement transducer (1) comprising first (2) and second (3) fixed capacitor plate and a dielectric structure (5) moveable longitudinally within a space (4) between the first (2) and second (3) capacitor plates, the dielectric structure (5) being operatively coupled to a moveable element (8). The capacitor plates and the dielectric material may be cylindrical and disposed coaxially and concentrically. The transducer (1) enables a displacement sensor that is capable of monitoring liquid levels in a syringe type drug reservoir (101) with sufficient sensitivity as to allow detection of erroneous drug delivery. The sensor is inexpensive to manufacture and provides reliable performance through robust design.

L'invention concerne un transducteur (1) à déplacement linéaire de la capacitance comportant une première (2) et une deuxième (3) plaque de condensateur fixes et une structure diélectrique (5) mobile longitudinalement dans lespace (4) compris entre la première (2) et la deuxième (3) plaque, et fonctionnellement reliée à un élément mobile (8) , lesdites plaques et ledit matériau diélectrique pouvant être cylindriques et disposés coaxialement et concentriquement. Le transducteur (1) confère à un détecteur de déplacements capable de suivre le niveau du liquide dans un réservoir (101) de médicament de type seringue suffisamment de sensibilité pour détecter ladministration erronée dun médicament. Le détecteur est peu coûteux à fabriquer, fiable et robuste.
