Peristaltic Pump

Abstract

A peristaltic pump for conveying fluids includes a stator and a rotor supported therein. A flexible hose is integrated in the stator and the rotor includes radially arranged conveying elements which squeeze the hose over a section containing the fluid. The squeezed fluid section moves progressively in the hose under the effect of a motor connected to the rotor. The conveying elements are designed as rotatably mounted rollers that include at least two rolling bearings, of which the outer rings are connected via a common outer sleeve and of which the inner rings are connected to the rotor. Under the effect of the motor, the rotor moves in the stator and the outer rings of the conveying elements roll on the inner surface of the stator.

1 - 3 . (canceled) 
     
     
         4 . A peristaltic pump for conveying fluids, comprising:
 a stator with an integrated flexible hose;   a rotor supported in the stator, wherein the rotor comprises radially arranged conveying elements configured to squeeze the hose over a section containing the fluid, and wherein the squeezed fluid section moves progressively in the hose under the effect of a motor connected to the rotor,   wherein the conveying elements are rotatably mounted rollers comprising at least two rolling bearings, of which outer rings are connected via a common outer sleeve and inner rings are connected to the rotor, and   wherein, under the effect of the motor, the rotor moves in the stator and the outer rings of the conveying elements roll on the inner surface of the stator.   
     
     
         5 . The peristaltic pump as claimed in  claim 4 , wherein the hose extends within the stator over a substantially circular path. 
     
     
         6 . The peristaltic pump as claimed in  claim 4 , wherein the hose is arranged in a region of an inlet to and of an outlet from the peristaltic pump with a common hose clamp that is connected to the stator.
