Title (EN) HAEMADYNAMOMETER
(FR) HEMODYNAMOMETRE
Abstract:
(EN) A haemadynamometer for automatic tonometry provided with a temporary sealing belt (1), an automatic pressure controller (2) to supply air under pressure in the belt, a circuit (22) to distinguish Korotkov"s sounds and a digital indicator (20) to display by digital signals the highest and the lowest blood pressure values. The automatic pressure controller (2) is so structured that the intermittent increase of the air supply is continued as long as Korotkov"s sounds are detected and that it is automatically switched to its exhaust phase when Korotkov"s sounds are no longer detected and during the exhaust process the highest and the lowest blood pressure values detected by means of the beginning and ending of Korotkov"s sounds are displayed by digital signals.
(FR) Un hemodynamometre pour mesure automatique de la tension arterielle comprend un bracelet pneumatique (1), un controleur automatique de pression (2) qui alimente le bracelet en air comprime, un circuit (22) de detection des sons de Korotkov et un indicateur numerique (20) permettant l"affichage des valeurs maximum et minimum de la pression sanguine. Le controleur automatique de pression (2) est concu de facon telle que l"alimentation en air se poursuit aussi longtemps que des sons de Korotkov sont detectes et que l"air comprime est relache lorsque cesse la detection des sons de Korotkov. Pendant l"echappement de l"air les valeurs de la pression maximum et de la pression minimum, dont la mesure correspond a l"apparition et la cessation des sons de Korotkov, sont affichees numeriquement.
