Apparatus for blood plasma separation
Abstract
Abstract An apparatus for centrifugally separating blood plasma from red blood cells, said apparatus being adapted for use with a blood bag set composed of a pair of mother bags and a daughter bag communicating therewith, said apparatus comprising a blood bag receiving box of generally inverted V-shape cross section having a pair of bottom plates hinged for upward movements, rotary drum, flywheel of larger inertia than that of the drum and a mechanism operable, after completion of blood plasma separation within said mother bags and after switching off of the power source of the apparatus, to upwardly urge the bottom plates of the blood bag box against the cover thereof by virtue of the difference in inertial rotation between the drum and the flywheel to thereby automatically squeeze the separated fluid of blood plasma out of the mother bags into the daughter bag.
