Abstract

L'invention concerne un appareil pour contrôler le liquide corporel sortant d'un cathéter en vue de capter et de mesurer le volume de liquide corporel en utilisant un récipient de mesure et de produire un signal électrique de mesure correspondant au volume de remplissage. Dans un cycle prédéterminé de mesures T, le signal de mesure peut être comparé en tant que valeur réelle à une valeur imposée qui est associée au volume de remplissage auquel on doit s'attendre pendant ledit cycle dans le cas d'un fonctionnement normal du corps; dans le cas d'une comparaison négative, un signal d'alarme est produit à l'aide d'un dispositif d'alarme 28 et le récipient de mesure 3 est vidé après chaque cycle de mesure. Elimination contrôlée d'urine du corps d'un patient.An apparatus for monitoring bodily fluid exiting a catheter for sensing and measuring the volume of bodily fluid using a measuring vessel and producing an electrical measurement signal corresponding to the filling volume. In a predetermined cycle of measurements T, the measurement signal can be compared as an actual value to a prescribed value which is associated with the filling volume which is to be expected during said cycle in the case of normal functioning of the body. ; in the case of a negative comparison, an alarm signal is produced using an alarm device 28 and the measuring vessel 3 is emptied after each measuring cycle. Controlled elimination of urine from a patient's body.
