Separator for extracting serum from blood sample in separation strip, comprising hinged upper and lower parts with projections for pressing serum from the strip on folding the parts together

摘要

A separator for extracting serum from a blood sample in a separation strip comprises a lower part (4) for receiving the strip, hinged (5) to an upper part (3). The upper part and/or the underside of the upper part has projection(s) (7a, 7b) for applying local pressure to the strip on folding the upper and lower parts together, so that serum exits from the back end of the strip on displacing the strip. An independent claim is included for separation strips for use in the separator, comprising a blood separation part; a holder for covering and fixing the separation part; a blood introduction section, formed in the section of the holder covering the front end of the separation part; and a blood extraction opening, formed in the section of the holder covering the back end of the separation part. At least one constriction is formed on the longitudinal side(s) of the strip and forms back and front buffers, so that the strip is movable over the distance defined by the buffers.
