Abstract

1495797 Peristaltic pumps VIAL SARL 13 Aug 1975 [24 Sept 1974] 33801/75 Addition to 1445472 Heading F1F The main invention is improved or modified in that a platen 8 against which the perfusion tube 4 is compressed by the rollers 3 has "ramps" CA, BD next the ends of a compression area AB so as to obtain a more uniform flow-rate. The profiles of the said area and ramps may be arcs of circles centred at 0, 0', 0". Grooves or slots 9 may be formed in the platen to render it resilient to minimize crushing of the constituents of the working fluid, which may be blood.
