Abstract: Attorney's Docket No. 7963 CAN           INVENTORS:  ARTHUR WINDISCH and HEINZ PFENNINGER            INVENTION:  METHOD AND APPARATUS FOR STORING AND MIXING BLOOD             SAMPLES     ABSTRACT OF THE DISCLOSURE           The apparatus for storing and mixing blood samples comprises a storage and mixing unit composed of a storage disc and a mixing disc for blood samples filled into test-tube like containers.  The coaxially arranged storage and mixing discs are driven independently of one another and are each provided with complementary grooves.  A loading device loads the containers housing the blood samples successively into the storage disc where they are transported to a transfer device.  The transfer device successively transfers the containers with the blood samples into an oppositely situated groove of the mixing disc.  This mixing disc rotates the containers with their blood samples during a predetermined mixing duration prior to transfer to a blood removal device.  This blood removal device rotates each container with its blood sample about the lengthwise axis thereof so that a bar code reading device can reliably read a bar code applied at the associated container for the blood sample independent of the container position.  Thereafter, the blood removal device withdraws blood from the blood sample of the related container and delivers such to a blood analyzer.  The mixing disc now rotates the container and its blood sample to an ejection position where this container and its blood sample are removed from the mixing disc and deposited into one of a number of receptacles provided for receiving the different types of blood samples.
