BLOOD BAG VALVE BREAKER

摘要

The invention relates to a blood bag valve breaker, in which the output shaft of the electromotor (1) is coupled with the excenter (2) inside the housing (K). The connecting lever (3) of the excenter-lever mechanism is rotationally connected on one end to the excenter (2), and on the other end to the push rod (4). On the push rod (4) the fork (5) is attached, beneath which a fixed fork (6) is placed on the housing (K). Beneath the fork (6) the spikes (7) with the slipped openings (82) constructed on the reinforcement (81) of the bag (8) are placed. Between the forks (5, 6) the valve (83) of the bag (8) is placed, in such a manner that the rotation axis of the fork (5) is positioned, approximately in the axis of the fork (6), that is in the centre of the valve (83). On the outer sides of their arms the movable fork (5) and the fixed fork (6) have built-in screws (51, 61), respectively, which through springs (not shown in the drawings), press the balls (52, 62), respectively, in between of which the valve (83) is positioned.
