Abstract

1445472 Peristaltic pumps VIAL SARL 22 Nov 1973 [22 Nov 1972] 54347/73 Heading F1F [Also in Division A5] In a peristaltic pumping device for apparatus comprising a drip set, rollers 13 compress a generally straight portion 22 of the infusion tube and may be mounted on a wheel 12 driven by an electric motor 32, which is controlled by a unit 32 in accordance with signals from a timer 23 and a photo-electric cell (30), Fig. 4 (not shown), at a drip-chamber (9) so as to effect dripping at the desired rate. A spring-loaded platen 18 is supported by a pivoted "gate" 16 to facilitate insertion and removal of the tube.
