Abstract

CET APPAREIL COMPREND ESSENTIELLEMENT UN TUBE ELASTIQUE 2 REMPLI D'UN ALLIAGE ELECTRO-CONDUCTEUR DE GALLIUM-INDIUM NE CONTENANT PAS DE MERCURE ET QUI EST LIQUIDE A LA TEMPERATURE AMBIANTE. CE TUBE EST FIXE A UNE SANGLE 1 DEPOURVUE D'ELASTICITE EN DES POINTS ESPACES 5 ET 6. LORSQUE L'APPAREIL EST ENROULE AUTOUR D'UN MEMBRE ET FIXE AU MOYEN DE LA SANGLE 1, LES VARIATIONS DU VOLUME DU SANG CONTENU DANS CE MEMBRE PROVOQUENT DES ALLONGEMENTS ET DETENTES DU TUBE 2 AVEC VARIATION CONSECUTIVE DE SA RESISTANCE OHMIQUE, QUE L'ON MESURE A L'AIDE D'UN INSTRUMENT. LA LONGUEUR DE LA SANGLE ENTRE LES POINTS DE FIXATION 5 ET 6 DU TUBE 2 EST LIMITEE A ENVIRON 120 DE LA LONGUEUR DE CE TUBE AFIN D'EVITER LES ALLONGEMENTS EXCESSIFS DE CE DERNIER.
