Title
(EN) DIVERSION OF EMBOLI DURING FLUID CIRCULATION
(FR) DERIVATIONS DES EMBOLES PENDANT LA CIRCULATION DU FLUIDE
Abstract
(EN)
Diversion of an embolus during fluid circulation in an extracorporeal circuit, comprising the steps of establishing a first circuit (100, 101a, 101b, 101c, 102, 103, 104, 106b, 106a, 107) between an outlet of a vascular system and an inlet of said vascular system; establishing a 5 second circuit (101b, 101c, 102, 103, 104, 106b, 108) configured to bypass said inlet and outlet; providing a fluid reservoir (102) a pumping means (103), and a bubble detector (105) in said circuits; detecting by means of said bubble detector (105) an embolus in said first circuit and sending a signal to an automatic embolus diversion supervisor (121) connected to said bubble detector (105); and controlling fluid flow direction means (110, 10 111) in dependence of the signal from said bubble detector (105); whereby said fluid flow direction means (110, 111) are controlled to redirect a detected embolus to said second circuit.
(FR)
La dérivation d'un embole pendant la circulation du fluide dans un circuit extracorporel comprend les étapes suivantes: la réalisation d'un premier circuit (100, 101a, 101b, 101c, 102, 103, 104, 106b, 106a, 107) entre une sortie d'un système vasculaire et une entrée dudit système vasculaire; l'établissement d'un circuit 5 secondes (101b, 101c, 102, 103, 104, 106b, 108) configuré pour dériver l'entrée et la sortie; la mise en place d'un réservoir de fluide (102), d'un moyen de pompage (103) et d'un détecteur de bulles (105) dans lesdits circuits; la détection, au moyen du détecteur de bulles (105) d'un embole dans le premier circuit et l'envoi d'un signal à un superviseur (121) de dérivation automatique d'embole connecté au détecteur de bulles (105); et la commande des moyens d'orientation du flux de fluide (110, 10 111) sur la base du signal provenant dudit détecteur de bulles (105), lesdits moyens d'orientation du flux de fluide (110, 111) étant commandés pour diriger un embole détecté, vers le deuxième circuit.
