Claims (6)

1. Schlauchpumpe mit einem Schlauch (10), zwei mit gegenseiti­ gem Abstand auf den Schlauch gesteuert einwirkenden Quetschventilen (V1, V2) und einem zwischen den Quetschven­ tilen angeordneten Pumpelement (12) zum Austreiben des in dem Schlauchabschnitt (10a) zwischen den Quetschventilen (V1, V2) befindlichen Flüssigkeitsvolumens, dadurch gekennzeichnet, dass im Bereich des Pumpelements (12) mindestens ein quer zur Bewegungsrichtung des Pumpelements (12) bewegbares Rückfor­ melement (17) zum Wiederherstellen des durch das Pumpele­ ment (12) deformierten Schlauchquerschnitts angeordnet ist.1. peristaltic pump with a hose ( 10 ), two pinch valves (V1, V2) acting with mutual distance on the hose and a pump element ( 12 ) arranged between the pinch valves for driving out the in the hose section ( 10 a) between the pinch valves (V1, V2) liquid volume, characterized in that in the area of the pump element ( 12 ) at least one transverse to the direction of movement of the pump element ( 12 ) movable forform element ( 17 ) is arranged to restore the tube cross-section deformed by the pump element ( 12 ). 2. Schlauchpumpe nach Anspruch 1, dadurch gekennzeichnet, dass das Rückformelement (17) im wesentlichen auf dieselbe Schlauchlänge einwirkt wie das Pumpelement (12).2. Hose pump according to claim 1, characterized in that the restoring element ( 17 ) acts essentially on the same hose length as the pump element ( 12 ). 3. Schlauchpumpe nach Anspruch 1 oder 2, dadurch gekennzeich­ net, dass die Breite des Pumpelements (12) nicht grösser ist als der Schlauchdurchmesser des unverformten Schlauches (10).3. Hose pump according to claim 1 or 2, characterized in that the width of the pump element ( 12 ) is not greater than the hose diameter of the undeformed hose ( 10 ). 4. Schlauchpumpe mit einem Schlauch (10), zwei mit gegenseiti­ gem Abstand auf den Schlauch gesteuert einwirkenden Quetschventilen (V1, V2) und einem zwischen den Quetschven­ tilen angeordneten Pumpelement (12) zum Austreiben des in dem Schlauchabschnitt (10a) zwischen den Quetschventilen (V1, V2) befindlichen Flüssigkeitsvolumens, dadurch gekennzeichnet, dass ein die Kraft des Pumpelements (12) messender Kraftsensor (13) am Pumpelement (12) oder am Gegenlager (11) vorgesehen ist.4. Peristaltic pump with a hose ( 10 ), two pinch valves (V1, V2) acting with mutual spacing on the hose and a pump element ( 12 ) arranged between the pinch valves for driving out the in the hose section ( 10 a) between the pinch valves (V1, V2) of the liquid volume, characterized in that a force sensor ( 13 ) measuring the force of the pump element ( 12 ) is provided on the pump element ( 12 ) or on the counter bearing ( 11 ). 5. Schlauchpumpe nach Anspruch 4, dadurch gekennzeichnet, dass ein den Hubweg des Pumpelements (12) messender Wegsensor vorgesehen ist und dass eine Veränderung des Kraftsignals anhand der Grösse oder Veränderung des Wegsignals bewertet wird.5. Peristaltic pump according to claim 4, characterized in that a displacement sensor measuring the stroke of the pump element ( 12 ) is provided and that a change in the force signal is assessed on the basis of the size or change in the displacement signal. 6. Schlauchpumpe nach einem der Ansprüche 1-5, dadurch gekenn­ zeichnet, dass der Antrieb des Rückformelements (17) einen Energiespeicher (19) enthält.6. Peristaltic pump according to one of claims 1-5, characterized in that the drive of the reforming element ( 17 ) contains an energy store ( 19 ).
