Abstract
Description
Schlauchpumpen werden z. B. in der Dialyse zum Bluttransport verwendet. Üblich sind Rollenpumpen, bei denen ein rotierender Rollenträger vorgesehen ist, wobei die Rollen ein Stück des Schlauches über seine Länge fortschreitend zusammendrücken und so die Flüssigkeit vorwärts befördern. Durch das Abrollen der Rollen auf dem Schlauch entsteht Reibung (Rollwiderstand) und Verschleiß. Die Drehzahl kann deswegen nur relativ niedrig sein.peristaltic pumps be z. B. used in dialysis for blood transport. Are common Roller pumps in which a rotating roller carrier is provided, wherein the Roll a piece the hose over his length squeezing progressively and so the liquid forward transport. By rolling the rollers on the hose creates friction (Rolling resistance) and wear. The speed can therefore be relatively low.

Die wesentlichen Vorteile der beschriebenen Schlauchpumpe sind:
- 1. Keine Rollreibung am Schlauch
2 ,2a (kein Darüberrollen über den Schlauch2 ,2a ). Hohe Drehzahlen sind möglich, daher ist kein vollständiges Zusammendrücken des Schlauches2 ,2a erforderlich; der Schlauchpressweg kann begrenzt werden. - 2. Schlauch
2 ,2a kann über seine Presslänge vorgespannt werden, daher sind geringe Schlauchpresswege erforderlich, d. h. es sind große Schlauchdurchmesser bei geringen Presswegen möglich. - 3. Die Stempel
6 sind durch die Stege7 miteinander zu einem Rad5 verbunden, daher müssen die Stempel6 nicht durch den Schlauch2 ,2a zurückgedrückt werden oder bei weichen Schläuchen durch Federn. Die Rückstellung der Stempel6 erfolgt durch die Form und Bewegung des Rotors8 .
- 1. No rolling friction on the hose
2 .2a (no rolling over the hose2 .2a ). High speeds are possible, so there is no complete compression of the hose2 .2a required; The hose pressing path can be limited. - 2nd hose
2 .2a can be biased by its press length, therefore, low Schlauchpresswege are required, ie it is possible large hose diameter at low pressure paths. - 3. The stamps
6 are through the bridges7 together to a wheel5 connected, therefore, must the stamp6 not through the hose2 .2a pushed back or soft tubes by springs. The provision of stamps6 is done by the shape and movement of the rotor8th ,
