Description
Ein Teil umfaßt einen extrakorporalen Blutkreislauf und der andere einen Kreislauf oder einen Strömungsweg für das Dialysat. Typischerweise stellt der gesamte Kreislauf für das Blut einen Wegwerfartikel dar und umfaßt: 1) eine arterielle und venöse Fistelnadel, 2) ein arterielles (Einström-) und venöses (Ausström-)Schlauchset, 3) ein Dialysegerät, 4) eine physiologische Vorbefüllungslösung (Salzlösung) mit Infusionsbesteck und 5) einen Gerinnungshemmer wie z. B. Heparin oder Natriumzitrat mit Infusionsbesteck. Über die arterielle Nadel wird dem Patienten über einen geeigneten Zugang Blut entnommen, das dann über die arteriellen Blutschläuche zum Dialysegerät geführt wird.
P = Lichtintensität der LED 530
KC = Lichtabschwächung der Küvette 536 und des Dialysats
KS = Abschwächungskoeffizient aufgrund von Blut im Dialysat
PEXT1, PEXT2 = externe, überlagernde Lichtquellen
KPD1, KPD2 = Empfindlichkeitskoeffizienten der Photodioden 538 bzw. 534
VOFF1, VOFF2 = elektronische Offsetkoeffizienten der Verstärker 546 bzw. 540
VPD1 = (P·KC·KS + PEXT1)KKD1 + VOFF1.
- - Angestrebtes KT/V pro Behandlung, mit K als Harnstoffclearance des Katalysators in ml pro Minute vollständig gereinigten Blutes, T als Behandlungszeit und V als Verteilungsvolumen (Harnstoff im Patienten), welches etwa 58% des Körpergewichts des Patienten in Kilogramm entspricht. Details der Korrelationsberechnungen zwischen Natrium und Harnstoff sind im US-Patent 5,110,477 von Howard et al. beschrieben, auf welches hiermit Bezug genommen wird;
- - minimale Behandlungszeit, unabhängig davon, ob die KT/V- Vorgabe in einer kürzeren Zeit erreicht wurde;
- - vorgegebene Blutflußrate, welche die maximalen arteriellen und venösen Drücke limitiert;
- - Vorgaben hinsichtlich Trockengewicht oder Wasserentnahme mit vorprogrammierten Grenzen in Bezug auf die maximale Rate, mit der Fluid entfernt werden kann (der Gewichtsverlust) wird dann dadurch berechnet, daß man das Trockengewicht von dem vorher gemessenen Gewicht abzieht und das zusätzlich infundierte Fluid beim Vorfüllen, Zurückspülen und anderen Gelegenheiten berücksichtigt; oder
- - zu entfernendes Fluid, wobei beispielsweise unter akuten Bedingungen die zu entfernende Menge benötigt werden kann, die anstelle des Patientengewichts auf den Infusionsvolumina basiert und, weil das System dann nicht in der Lage ist, die Menge des zu entnehmenden Fluids aus der Relation Gewicht minus Trockengewicht automatisch zu berechnen, der Operator die zu entnehmende Fluidmenge direkt angeben muß.
