Title (EN) TUBULAR PRESSURE TRANSDUCER
(FR) TRANSDUCTEUR DE PRESSION TUBULAIRE
Abstract:
(EN) In a blood pressure monitoring system, a transducer (12) which is a conductive rubber tube (16) having conductive terminals (19) at each end. In alternative embodiments, a nonconductive tube has a semiconductive stripe (31) or band or an ion-implanted stripe (41) or band (42) forming the pressure-responsive element.
(FR) Transducteur (12), utilisé dans un système de contrôle de pression sanguine, se présentant sous la forme d'un tube en caoutchouc conducteur (16) doté de bornes conductrices (19) à chaque extrémité. Dans d'autres modes de réalisation, un tube non conducteur comporte une bande semi-conductrice (31) ou une bande à implantation ionique (41), ou bien une bande (42) formant l'élément sensible à la pression.
