Title (EN) LIVING BODY CONDITION MEASURING APPARATUS
(FR) APPAREIL POUR MESURER L'ETAT D'UN ORGANISME VIVANT
Abstract:
(EN) An apparatus for uninvasively evaluating hemodynamic parameters, particularly a sphygmographic analyzer for evaluating vessel compliance and flow resistance in the central and peripheral portions of the artery system separately. A microcomputer (4) detects the radial artery wavefrom of an object through a sphygmograph (1), and fetches a stroke output of the object from an output meter. Next, the value of each of the five elements that constitute an electric circuit simulating the artery system ranging from the central portion to the peripheral portion of the living body is adjusted on the basis of the stroke output so that when an electric signal corresponding to a pressure wave of the aortic origin of the object is applied to the electric circuit, its response waveform corresponds to the radial artery waveform, and the resulting value of each element is outputted as the hemodynamic parameter. Further, the pulse waveform, the maximum blood pressure value and the minimum blood pressure value at the aortic origin are calculated from the value of each element, and the calculation result is outputted to an output device (6).
(FR) Appareil permettant de mesurer de manière non invasive les paramètres hémodynamiques, notamment analyseur sphygmographique permettant de mesurer la compliance vasculaire et la résistance à l'écoulement dans la partie centrale et la partie périphérique du système artériel séparément. Un micro-ordinateur (4) détecte l'onde de pouls de l'artère radiale d'un sujet par l'intermédiaire d'un sphygmographe (1) et va chercher une onde de choc dans un dispositif de mesure des sortie. Puis on règle la valeur de chacun des cinq éléments qui constituent un circuit électrique simulant le système artériel, depuis la partie centrale jusqu'à la partie périphérique de l'organisme, sur la sortie de l'onde de choc, de façon que, lorsqu'on envoie dans le circuit électrique un signal électrique correspondant à une onde de pression de l'origine aortique, l'onde de réponse corresponde à l'onde de l'artère radiale, et que la résultante de chaque élément sorte en tant que paramètre hémodynamique. On calcule ensuite l'onde de pouls, la tension artérielle maximum et la tension artérielle minimum au niveau de l'origine aortique à partir de la valeur de chaque élément, et le dispositif de sortie (6) donne le résultat obtenu.
