Abstract

L'invention concerne un brassard destiné à un dispositif de mesure de données de pression artérielle, dans lequel le coefficient de frottement entre un second tissu extérieur (166b) et un second tissu intérieur (166e), dans une région d'enroulement (R2) d'une enveloppe (166) du type poche, est réduit par l'interposition d'une feuille réduisant le frottement (171). Par conséquent, le brassard de l'invention destiné à un dispositif de mesure de données de pression artérielle et le dispositif de mesure de données de pression artérielle pourvu de ce brassard permettent de mesurer des changements de la pression artérielle avec un bon degré de précision, même si on utilise un grand brassard avec le dispositif de mesure de données de pression artérielle.
