PURPOSE:To separate a fixed quantity of blood plasma, by compressing a blood gathering bag by a certain width at the time of putting a blood gathering bag between a wall board and a pressing board of a blood plasma separator. CONSTITUTION:A blood gathering bag is hung on a hanger 6 and a pressing board 3 is sprung up by a spring by removing a lever 5 and then, said bag is put between the board 3 and a wall board 2. At this time, a micromotor 17 is driven because a connection element of the bag is connected with metallic plate electrically contacting terminals 10, 10. A rod 15 stuck to the board 3 is retreated and squeeze pressure for the bag is given by the force of a leaf spring attached to an axis of the board 3. When the rod 15 is brought into contact with a microswitch SW3 by retreating the rod 15 for a fixed width, a solenoid 16 is operated and a connecting tube is closed. |
