Procédé et dispositif de nettoyage et remplissage en ligne d'un circuit extracorporel sanguin d'une machine

Process and device for on-line cleaning and filling of an extra corporeal blood circuit of a dialysis apparatus

Verfahren und Anordnung zum On-Line Spülen und Befüllen eines extrakorporalen Blutkreislaufes von Dialysemaschinen

Abstract

According to the on-line process of the invention, haemodialysis solution produced or processed by the dialysis apparatus (1) is removed at the blood side from the dialyser (8) and pumped through the blood tube lines (10, 11), either by means of the blood pump (14) belonging to the apparatus or by the pump included in the haemodialysis solution circulation, where appropriate using the machine-specific filling program. This dispenses with the need to clean and fill the extracorporeal blood circulation with a saline solution, which has hitherto incurred considerable costs. …<IMAGE>…
Nach dem erfindungsgemäßen On-Line Verfahren wird von der Dialysemaschine (1) erzeugte bzw. aufbereitete Dialysierflüssigkeit blutseitig dem Dialysator (8) abgenommen und entweder mittels der maschineneigenen Blutpumpe (14) oder der Pumpe des Dialysierflüssigkeitskreislaufs, gegebenenfalls unter Verwendung des maschinenspezifischen Füllprogramms, durch die Blutschlauchleitungen (10,11) gepumpt. Hierdurch entfällt das Erfordernis, den extrakorporalen Blutkreislauf mittels einer Kochsalzlösung zu spülen und zu befüllen, was bisher mit beträchtlichen Kosten verbunden war.
