Abstract

L'invention porte sur un dispositif hémostatique pouvant détecter la pression réelle appliquée sur un site où un saignement doit être arrêté, permettant ainsi d'empêcher des variations de la pression appliquée sur le site provoquées par différents opérateurs. Un dispositif hémostatique (1) comporte une bande (2) conçue pour être enroulée autour d'un membre (500) à un site (510) sur celui-ci où un saignement doit être arrêté, un élément de fixation de surface (3) (élément de fixation) fixant la bande dans un état enroulé au membre, un ballon (5) attaché à la bande et se gonflant lorsqu'un fluide est introduit dans celui-ci, et un capteur de pression (110) détectant la pression avec laquelle le ballon gonflé exerce une pression sur le site où le saignement doit être arrêté.
