Abstract

La présente invention concerne un sphygmomanomètre (1) qui comprend une unité de brassard (2) ayant une longueur de périphérie extérieure fixe et porté sur l'avant-bras T d'un sujet sur qui une mesure doit être réalisée, et une unité d'affichage (63) destinée à afficher la valeur de pression artérielle mesurée, le sphygmomanomètre (1) recevant des signaux de pression d'un capteur de pression et commandant un moyen de pressurisation et de dépressurisation avec un moyen de commande pour détecter les sons de Korotkoff pour mesurer la pression artérielle. L'unité de brassard (2) renferme une poche d'air bloquant la circulation sanguine (14) pour bloquer la circulation sanguine de l'avant-bras lorsqu'il est porté sur l'avant-bras ainsi que deux poches d'air pour détecter les sons de Korotkoff (50) disposées de manière à ce que les poches d'air se trouvent à des positions opposées l'une de l'autre lorsque l'unité de brassard est portée sur l'avant-bras T. Les moyens de pressurisation comprennent deux pompes (110) destinées à alimenter l'air dans les poches d'air bloquant la circulation sanguine (14) et les deux poches d'air destinées à détecter les sons de Korotkoff (50), et le tissu extérieur (16) constituant l'unité de brassard (2) est formé par un matériau non étirable dans les sens circonférentiel et longitudinal.
