Traditional cuffs for measuring blood pressure use an air chamber enclosed in a non-stretchable fabric to occlude an artery in a limb when supplied with pressurised air. A stethoscope used on the limb is used to monitor blood flow. Application of the cuff is inconvenient and correct placement of the stethoscope chestpiece requieres skill. According to the invention blood pressure measurement is facilitated by having the air chamber enclosed in a pre-formed shell like structure being flexible around the limb and stiff along the limb and by using a linear array of microphones to detect the blood flow noises, the best signal from one of the microphones being automatically selected. Furthermore, the invention provides a facility for correcting the reading in dependence of the amount of wrap of the limb.

Les brassards traditionnels servant à mesurer la pression artérielle comprennent une chambre à air entourée d'un toile non extensible qui sert à bloquer l'artère d'un membre lorsqu'elle est alimentée en air pressurisé. Un stéthoscope mis en place sur le membre sert à surveiller le flux sanguin. L'application du brassard n'est pas pratique et le positionnement de la plaque thoracique du stéthoscope requière des compétences. Selon l'invention, la mesure de la pression artérielle est facilitée par la présence d'une chambre à air entourée d'une structure de type coque préformée qui est flexible sur la circonférence du membre et rigide dans le sens de la longueur du membre, et par l'utilisation d'un réseau linéaire de microphones qui servent à détecter les bruits de circulation sanguine, le meilleur signal issu de l'un des microphones étant automatiquement sélectionné. De plus, l'invention donne une possibilité de corriger la lecture en fonction de l'ampleur de l'enveloppement du membre.
