Abstract

1437494 Peristaltic pumps RHONEPOULENCSA 11 Sept 1973 [12 Sept 1972] 4933/75 Divided out of 1437493 Heading F1F [Also in Division A5] A statorless blood-pump assembly comprises a motor 12 with first and second rotors driving respectively pump "bodies" 6 and 10, the useful internal volume and hence flow-rate of each body varying between minimum and maximum limits proportionally to its inlet blood pressure, the useful volume of body 6 reaching a maximum within the range of atmospheric pressure 0 to -20 mm of mercury and that of body 10 reaching a minimum within the range of atmospheric pressure 0 to +20 mm of mercury. Body 10, with an elliptical crosssection at rest, has a higher useful maximum flowrate and a lower useful minimum flow-rate than body 6, the latter body having a circular crosssection at rest of shorter internal perimeter than body 10.
