Abstract
Description
Die Erfindung betrifft eine peristaltische Schlauchpumpe mit einer Welle, die mehrere Exzenterscheiben aufweist, von denen jede ein Lager trägt und damit einen Pumpenfinger quer zu einem Pumpenschlauch bewegt, und mit einer zwischen der Welle und dem Pumpenschlauch angeordneten Dichtmembran.The invention relates to a peristaltic peristaltic pump a shaft that has several eccentric discs, one of which each carries a bearing and thus a pump finger across one Pump hose moves, and with one between the shaft and the Pump hose arranged sealing membrane.
Peristaltische Schlauchpumpen werden häufig als Infusions- oder Transfusionspumpen zur Förderung flüssiger Substanzen im medizinischen Bereich eingesetzt. Bekannt sind lineare Schlauchpumpen, bei denen ein gerader Pumpenschlauch von zahlreichen Pumpenfingern fortlaufend und zyklisch gegen ein Widerlager gedrückt wird, so dass die Flüssigkeit in dem Pumpenschlauch in Förderrichtung bewegt wird. EP 0 214 443 A1 beschreibt eine peristaltische lineare Schlauchpumpe mit zahlreichen an einer Welle befestigten Exzenterscheiben. Jede Exzenterscheibe trägt ein Kugellager und wirkt auf einen linear bewegbaren Pumpenfinger. Sämtliche Pumpenfinger werden von einer Dichtmembran überspannt, die eine abdichtende Trennung zwischen dem Antriebsmechanismus und dem Pumpenschlauch bildet. Dadurch werden Beschädigungen und Verschmutzungen des Pumpenschlauchs vermieden. Andererseits wird das Innere der Pumpe gegen eindringende Flüssigkeit geschützt. Eine so angeordnete Dichtmembran beeinflusst die Fördergenauigkeit negativ. Sie bewirkt eine Kraftkopplung zwischen benachbarten Pumpenfingern, wodurch auch der elektrische Energieverbrauch erhöht wird. Ein Teil der Rückstellkräfte des Pumpenschlauches wird bei dieser Membrananordnung benötigt, um die Dichtmembran gegen die Pumpenfinger zu verformen. Das kann zum vorzeitigen Nachlassen der Rückstellkräfte führen. Infusionspumpen, wie beispielsweise peristaltische Schlauchpumpen, sollen möglichst klein und leichtgewichtig gebaut werden. Daher ist es wichtig, den Energiebedarf zu verringern, um Bauteile wie Akku, Netzteil und Antriebsmotor möglichst klein zu dimensionieren. Gleichzeitig ist die Forderung nach Einhaltung der angewählten Förderrate, auch während langer Infusionszeiten zu erfüllen.Peristaltic peristaltic pumps are often called infusion or Transfusion pumps for pumping liquid substances in medical Area used. Linear peristaltic pumps are known, where a straight pump hose from numerous pump fingers continuously and cyclically pressed against an abutment is so that the liquid in the pump hose in Direction of conveyance is moved. EP 0 214 443 A1 describes a peristaltic linear peristaltic pump with numerous at one Shaft-mounted eccentric discs. Every eccentric disc carries a ball bearing and acts on a linearly movable pump finger. All pump fingers are covered by a sealing membrane, which is a sealing separation between the drive mechanism and forms the pump hose. This will cause damage and contamination of the pump hose avoided. on the other hand is the inside of the pump against liquid ingress protected. A sealing membrane arranged in this way influences the funding accuracy is negative. It causes a coupling of forces between adjacent pump fingers, which also causes the electrical Energy consumption is increased. Part of the restoring forces the pump hose is required with this membrane arrangement, to deform the sealing membrane against the pump fingers. The can lead to premature release of the restoring forces. Infusion pumps, such as peristaltic peristaltic pumps, should be built as small and lightweight as possible. Therefore, it is important to reduce the energy requirement to components such as battery, power supply and drive motor as small as possible dimension. At the same time, the demand for compliance the selected delivery rate, even during long infusion times to fulfill.
Der Erfindung liegt die Aufgabe zugrunde, eine peristaltische Schlauchpumpe zu schaffen, die kleinformatig hergestellt werden kann, einen geringen Energiebedarf hat und eine gute Fördergenauigkeit bei langen Infusionszeiten hat.The invention has for its object a peristaltic To create peristaltic pumps that are manufactured in small format can, has a low energy requirement and good conveying accuracy with long infusion times.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Anspruch 1 angegebenen Merkmalen. Hiernach sind die Lager auf den Exzenterscheiben der Welle jeweils mit einer Pleuelstange verbunden, welche an einem linear geführten Pumpenfinger angreift. Die Pumpenfinger sind auf der dem Pumpenschlauch zugewandten Seite (Außenseite) der Dichtmembran angeordnet und die Pleuelstangen gehen durch die Dichtmembran hindurch.This object is achieved with the im Claim 1 specified features. After that, the camps are open the eccentric discs of the shaft with a connecting rod connected, which acts on a linearly guided pump finger. The pump fingers are on the side facing the pump hose Side (outside) of the sealing membrane arranged and the Connecting rods go through the sealing membrane.
Dadurch dass die Dichtmembran nicht die Pumpenfinger überspannt, erfolgt keine ständige periodische Dehnung der Dichtmembran zwischen benachbarten Pumpenfingern. Dadurch wird weniger Antriebsenergie benötigt. Die noch benötigten Kräfte, die Membran zu verformen, müssen nicht durch die Rückstellkräfte des Pumpenschlauches aufgebracht werden, sondern werden durch den Pumpenantrieb bereitgestellt. Hierdurch wird die Förderratengenauigkeit über längere Infusionszeiten verbessert. Außerdem wird der Verschleiß der Dichtmembran verringert. Die Verwendung von Pleuelstangen ermöglicht einen einfachen und kleinen Durchgang durch die Dichtmembran. Die Dichtmembran sollte keine gespannte Fläche bilden, sondern eine lose Faltenmembran sein, die sich den Bewegungen der Pleuelstangen anpasst, ohne dass wesentliche Materialspannungen auftreten.Because the sealing membrane does not span the pump fingers, there is no constant periodic expansion of the sealing membrane between adjacent pump fingers. This will make less Drive energy needed. The forces still needed, the The restoring forces do not have to deform the membrane of the pump hose are applied, but are by provided the pump drive. This makes the delivery rate accuracy improved over longer infusion times. Moreover the wear of the sealing membrane is reduced. The usage of connecting rods enables simple and small Passage through the sealing membrane. The sealing membrane should do not form a stretched surface, but a loose fold membrane that adapts to the movements of the connecting rods without that significant material stresses occur.
Durch die Erfindung werden störende Einflüsse der Dichtmembran auf die Fördergenauigkeit verhindert. Die Dichtmembran wird nicht gewalkt und nicht zwischen Pumpenfinger und Pumpenschlauch gequetscht.The invention eliminates interfering influences of the sealing membrane on the conveying accuracy prevented. The sealing membrane is not tumbled and not between pump finger and pump hose crushed.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die Dichtmembran zu beiden Seiten des Pumpenschlauchs Falten aufweist, die eine Anpassung an die Querbewegungen der Pleuelstange ermöglichen.According to a preferred development of the invention, that the sealing membrane on both sides of the pump hose Has folds that adapt to the transverse movements enable the connecting rod.
Auf der Seite des Pumpenschlauchs ist vorzugsweise eine Führungsplatte mit einem längslaufenden Aufnahmekanal für den Pumpenschlauch und mit Führungskanälen für die Pumpenfinger vorgesehen. Diese Führungsplatte ist zweckmäßigerweise für Reinigungszwecke herausnehmbar.A guide plate is preferably on the side of the pump hose with a longitudinal intake channel for the pump hose and provided with guide channels for the pump fingers. This guide plate is expedient for cleaning purposes removable.
Eine besondere Ausführungsform ist so aufgebaut, dass die Exzenterscheiben der Welle einstückig angeformt sind. Die Welle bildet somit gewissermaßen eine Kurbelwelle. Der äußere Mantel der Exzenterscheiben kann so geformt sein, dass er gleichzeitig die innere Laufbahn eines Kugellagers bildet. An die Kugellageraußenringe, welche ebenfalls in Spritzgusstechnik herstellbar sind, können die Pleuelstangen direkt angeformt werden. Durch diese Gestaltung wird die Anzahl der benötigten Bauteile verringert und die Reibung wird herabgesetzt. Damit ist wiederum ein geringerer Energieverbrauch verbunden.A special embodiment is constructed so that the eccentric discs the shaft are integrally formed. The wave thus forms a crankshaft, so to speak. The outer coat the eccentric disc can be shaped so that it is simultaneously forms the inner raceway of a ball bearing. To the ball bearing outer rings, which can also be manufactured using injection molding technology the connecting rods can be molded directly. With this design, the number of components required is reduced and the friction is reduced. That is again associated with lower energy consumption.
