Abstract

The pump has a pump body (1) and a receiving part (1a) for the hose (2) in a recess (3). A wheel (5) with rams (6) is based on a non-round rotor (8), which presses the rams against the hose and withdraws them from it in succession.

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 are e.g. used in dialysis for blood transport. Usual are roller pumps, in which a rotating roller carrier is provided, wherein the rollers gradually compress a piece of the tube over its length, thus conveying the liquid forward. By rolling the rollers on the hose creates friction (rolling resistance) and wear. The speed can therefore be relatively low.

Durch die deutsche Offenlegungsschrift DE 1911874 A1 ist eine Schlauchpumpe bekannt, bei der der Schlauch durch die eine Seite schwenkbarer, aufeinanderfolgend betätigter Druckfinger gegen eine Auflagefläche für den Schlauch gepresst wird. Hierzu ist ein rotierender Exzenter vorgesehen, der auf die andere Seite der Druckfinger einwirkt. Die Schlauchpumpe besteht aus vielen Einzelteilen, weist ein großes Volumen auf und ist störanfällig und teuer.By the German Offenlegungsschrift DE 1911874 A1 a peristaltic pump is known in which the hose is pressed by the side of a pivotable, successively operated pressure fingers against a support surface for the hose. For this purpose, a rotating eccentric is provided, which acts on the other side of the pressure fingers. The peristaltic pump consists of many parts, has a large volume and is prone to failure and expensive.

Dies gilt auch für die Schlauchpumpe gemäß der deutschen Offenlegungsschrift DE 2152352 A1 , bei der der Schlauch an einer zylindrischen Innenfläche anliegt und durch einen umlaufenden Exzenterkörper fortschreitend zusammengedrückt wird, wobei zwischen Schlauch und Exzenterkörper in einem Ring radial beweglich geführte Druckkörper angeordnet sind.This also applies to the peristaltic pump according to the German Offenlegungsschrift DE 2152352 A1 in which the tube rests against a cylindrical inner surface and is progressively compressed by a circumferential eccentric body, wherein between the hose and the eccentric body in a ring radially movably guided pressure body are arranged.

Aus FR 1 430 288 ist eine Schlauchpumpe mit einem Aufnahmeteil für einen flexiblen Schlauch in einer Aussparung und einem Ring mit mehreren radial verlaufenden Stempeln, die mit ihren äußeren Enden gegen den in der Aussparung liegenden Schlauch drückbar sind, bekannt. Ferner wirkt auf das innere Ende der Stempel ein motorisch angetriebener, unrunder Rotor derart, dass die Stempel bei der Rotation des Rotors fortschreitend gegen den Schlauch gedrückt und danach in entgegengesetzter Richtung zur Freigabe des Schlauchs nacheinander wieder zurückbewegt werden. Darüber hinaus sind die Stempel an ihren äußeren Enden von einem elastischen Band umschlungen, das die Stempel mit ihren inneren Enden gegen den Rotor drückt. Die Stempel sind in Bohrungen eines Ringes längsverschiebbar geführt. Die Schlauchpumpe ist aus relativ vielen Einzelteilen aufwendig aufgebaut.Out FR 1 430 288 is a hose pump with a receiving part for a flexible hose in a recess and a ring with a plurality of radially extending punches which are pressed with their outer ends against the tube lying in the recess known. Furthermore, acts on the inner end of the punch, a motor-driven, non-circular rotor such that the punch is pressed during the rotation of the rotor progressively against the hose and then moved back in the opposite direction to release the hose one after the other. In addition, the stamps are wrapped at their outer ends by an elastic band, which presses the punch with their inner ends against the rotor. The stamps are in holes a ring guided longitudinally displaceable. The peristaltic pump is made up of relatively many individual parts consuming.

Der Erfindung liegt die Aufgabe zugrunde, eine Schlauchpumpe aus wenigen Einzelteilen aufzubauen und den Rollwiderstand zu verhindern, so dass auch höhere Drehzahlen möglich sind und der Verschleiß des Schlauches gering ist.The invention has for its object to build a peristaltic pump of a few items and to prevent rolling resistance, so that higher speeds are possible and the wear of the hose is low.

Die Erfindung ist nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

The invention is explained below with reference to the drawing. Show it:
  • 1 is a view of a hose pump according to the invention with the lid open,
  • 2 is a section along the line II-II in Fig. 1,
  • 3 and 4 variants of the hose storage in the hose pump according to FIGS. 1 and 2,

  • Fig. 6 shows a variant of the inner part of the peristaltic pump. Figs. 1 and 2, wherein the sliding friction is avoided.

In den Fig. 1 und 2 ist mit 1 ein Pumpenkörper und mit 1a ein Aufnahmeteil, z. B. aus Kunststoff, für einen Schlauch 2 bezeichnet. Der Schlauch 2 besteht aus flexiblem Material und liegt in einer Aussparung 3 , die sich aus Pumpenkörper 1 und Aufnahmeteil 1a ergibt. Die Aussparung 3 ist durch einen Kunststoffdeckel 4, der in Fig. 1 weggelassen ist, verschlossen.In Figs. 1 and 2, 1 is a pump body and 1a a receiving part, for. B. plastic, designated for a hose 2. The hose 2 is made of flexible material and is located in a recess 3, which results from pump body 1 and receiving part 1a. The recess 3 is closed by a plastic cover 4, which is omitted in Fig. 1.

In der Aussparung 3 ist ein Rad 5 mit mehreren etwa radial liegenden Stempeln 6 angeordnet, welche durch federnde Stege 7 miteinander verbunden sind. Die Stempel 6 werden mit ihren äußeren Enden durch einen unrunden, z. B. elliptischen Rotor 8 fortschreitend gegen den Schlauch 2 gedrückt und liegen mit ihren inneren Enden am Rotor 8 an. Bei der Rotation des Rotors 8, z. B. in Richtung des Pfeils 9, wird der Schlauch 2 durch die Stempel 6 peristaltisch fortschreitend zusammengedrückt und die Stempel 6 werden danach zur Freigabe des Schlauches 2 nacheinander wieder zurückbewegt. Dadurch wird Flüssigkeit vom Eingang 10 zum Ausgang 11 befördert. Ein Elektromotor 12 treibt den Rotor 8 an.In the recess 3, a wheel 5 is arranged with a plurality of approximately radially located punches 6, which are interconnected by resilient webs 7. The stamp 6 are with their outer ends by a non-circular, z. B. elliptical rotor 8 progressively pressed against the tube 2 and lie with their inner ends on the rotor 8 at. During the rotation of the rotor 8, z. B. in the direction of arrow 9, the tube 2 is compressed by the plunger 6 progressively peristaltic and the punch 6 are then moved back to release the tube 2 in succession. This will be liquid from the entrance 10 to the exit 11. An electric motor 12 drives the rotor 8.

In der Fig. 3 ist eine Variante im Bereich III der Fig. 2 gezeigt. Dabei ist auf dem den Stempeln 6 gegenüber liegenden Schlauchbett 13 der Aussparung 3 ein nachgiebiges Material 14 aufgebracht, das ein zu starkes Quetschen des Schlauches 2 verhindert. Alternativ können auch die Stempel 6 in ihrer Längsrichtung federnd ausgebildet sein.FIG. 3 shows a variant in region III of FIG. 2. In this case, a yielding material 14 is applied to the punches 6 opposite the tube bed 13 of the recess 3, which prevents excessive squeezing of the tube 2. Alternatively, the punch 6 may be formed resiliently in its longitudinal direction.

Zwischen diesem Material 14 und dem Schlauch 2 liegt gem. Fig. 4 ein U-förmiges Aufnahmeteil 15, in dem der Schlauch 2 zwischen den als Anschläge 16 dienenden Seiten liegt, das auf dem elastischen Material 14 aufliegt und in Richtung zum Schlauchbett 13 der Aussparung 3 bewegbar ist. Dadurch wird der Pressweg des Schlauches 2 begrenzt. Letzterer wird nicht vollständig zusammengepresst und damit z. B. die Hämolyse-Rate von Blutpumpen gesenkt.Between this material 14 and the hose 2 is gem. Fig. 4 is a U-shaped receiving part 15 in which the tube 2 is located between serving as stops 16 sides, which rests on the elastic material 14 and is movable in the direction of the tube bed 13 of the recess 3. As a result, the pressing path of the hose 2 is limited. The latter is not completely compressed and thus z. B. lowered the hemolysis rate of blood pumps.

Die Fig. 5 zeigt, dass der Schlauch 2 zwischen dem Rad 5 (Stempel 6) und dem Schlauchbett 13 vorgespannt werden kann, so dass die Walkarbeit verringert ist. In der Aussparung 3 ist ein weiterer, nicht vorgespannter Schlauch 2a angeordnet. Die Schlauchpumpe kann also gleichzeitig mit mehreren Schläuchen arbeiten.Fig. 5 shows that the hose 2 between the wheel 5 (punch 6) and the hose bed 13 can be biased so that the flexing is reduced. In the recess 3, a further, unbiased hose 2a is arranged. The hose pump can therefore work simultaneously with several hoses.

Bei der Variante gemäß Fig. 6 liegt an den inneren Enden der Stempel 6 ein flexibler Ring 17 an und zwischen diesem Ring 17 und dem Rotor 8 befinden sich Wälzkörper 18, die durch einen flexiblen Käfig 19 geführt werden. Gleitende Reibung zwischen den Stempeln 6 und dem Rotor 8 ist dadurch verhindert.In the variant of FIG. 6 is located at the inner ends of the punch 6, a flexible ring 17 and between this ring 17 and the rotor 8 are rolling elements 18, which are guided by a flexible cage 19. Sliding friction between the punches 6 and the rotor 8 is thereby prevented.

Die wesentlichen Vorteile der beschriebenen Schlauchpumpe sind:

  1. 1. Keine Rollreibung am Schlauch 2, 2a (kein Darüberrollen über den Schlauch 2, 2a). Hohe Drehzahlen sind möglich, daher ist kein vollständiges Zusammendrücken des Schlauches 2, 2a erforderlich; der Schlauchpressweg kann begrenzt werden.
  2. 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. 3. Die Stempel 6 sind durch die Stege 7 miteinander zu einem Rad 5 verbunden, daher müssen die Stempel 6 nicht durch den Schlauch 2, 2a zurückgedrückt werden oder bei weichen Schläuchen durch Federn. Die Rückstellung der Stempel 6 erfolgt durch die Form und Bewegung des Rotors 8.
The main advantages of the hose pump described are:
  1. 1. No rolling friction on the hose 2, 2a (no rolling over the hose 2, 2a). High speeds are possible, so no complete compression of the tube 2, 2a is required; The hose pressing path can be limited.
  2. 2. Hose 2, 2a can be biased over its press length, therefore, low Schlauchpresswege are required, ie, it is possible large hose diameter at low Presswegen.
  3. 3. The punches 6 are connected by the webs 7 to each other to a wheel 5, therefore, the punch 6 must not be pushed back through the tube 2, 2 a or soft tubes by springs. The provision of the punch 6 is effected by the shape and movement of the rotor eighth
