Abstract

A peristaltic pump comprises at least two elastically compressible hose conduits (6), each having an inlet end and an outlet end and mutually identical cross section, a support means for each hose conduit (6), said support means having a curved surface (4) which is similar for all the hose conduits and which is engaged by the associated hose conduit (6) with at least a portion of the length thereof and at least two synchronously driven rotor units (1), one for each hose conduit (6), which are provided with the same number, at least two, of symmetrically arranged and mutually at the same distance from the rotor axis (2) operating pressure means (3) for local compression of the hose conduit (6) corresponding to each rotor unit (1), against the curved surface (4) of the associated support means. The number of pressure means (3) on each rotor unit (1) and the extention of said curved surface (4) on the support means of each hose conduit (6), seen in the longitudinal direction thereof, are mutually so adapted that continously one of the pressure means (3) on each rotor unit (1) compresses the corresponding hose conduit (6) for preventing fluid flow through the hose conduit in a direction opposite to the direction of rotation of the rotor unit. In order to provide a peristaltic pump permitting a non-pulsatile flow, at least the outlet ends of the hose conduits (6) forming part of the pump are joined into a common outlet (7) in a manner known per se, and the synchronously driven rotor units (1) are angularly displaced relative to each other such that their pressure means (3) operate with phase displacement on each hose conduit (6), whereby the flow pulsations generated in each hose conduit will at least to a substantial extent neutralize each other at the common outlet (7) of the hose conduits (6).
