Abstract

1511529 Fluid regulation UNION CHIMIQUE CONTINENTALE 8 Aug 1975 [8 Aug 1974] 33200/75 Heading G3H In apparatus for regulating the frequency of drops through a dropping chamber 5 of a clinical perfusion unit, a Piezo-electric ceramic element 1 applies pulses of ultrasonic vibrations to the liquid entering the chamber to retard the entry of drops thereinto. Means are provided for regulating the frequency and size of the pulses. The apparatus may be associated with an audible or visual alarm to indicate incorrect dropping frequency.
