Title
(EN) NOVEL EXTRACORPOREAL HEMODIALYSIS CIRCUIT
(FR) NOUVEAU CIRCUIT EXTRA-CORPOREL D’HEMODIALYSE
Abstract
(EN) The invention concerns the design of a novel arteriovenous extracorporeal circuit used in hemodialysis in patients suffering from renal failure; said novel circuit enables novel functions to be performed by the physician which have beneficial effects on the quality of hemodialysis and on the patient's safety. Among these novel manipulations, the following can be mentioned: extraction of blood clots formed in the circuit; high-flow rate rinsing of the circuit and of the dialyser. The invention concerns this novel circuit and its components (a novel arterial bubble trap, a novel venous bubble trap, a recycling line, a blood clot sensor) and to protect all the types of their constituent assemblies as well as the various models of the novel extracorporeal hemodialysis circuit.
(FR) L'invention consiste à la conception d'un nouveau circuit extracorporel artério­veineux utilisé en hémodialyse chez les insuffisants rénaux ; ce nouveau circuit permet au médecin d'effectuer des nouvelles fonctions qui ont des répercussions favorables sur la qualité d'hémodialyse et sur la sécurité du malade. parmi ces nouvelles manipulations nous citons particulièrement - L'extraction des caillots sanguins formés dans le circuit. - Le rinçage à haut débit du circuit et du dialyseur. L'objet de la protection consiste à protéger ce nouveau circuit et ses composants (un nouveau piège à bulle artériel, un nouveau piège à bulle veineux, une ligne de recirculation, un capteur des caillots) et de protéger toute les variétés de leurs assemblages constituants ainsi les différents modèles du nouveau circuit extracorporel d'hémodialyse.
