PCT No. PCT/AT94/00196 Sec. 371 Date May 31, 1996 Sec. 102(e) Date May 31, 1996 PCT Filed Dec. 14, 1994 PCT Pub. No. WO95/16395 PCT Pub. Date Jun. 22, 1995The invention describes a holding device (2) for a blood sample removal tubule (3) of a blood removal device (1) with a receiving vessel (11) for a front end of the blood sample removal tubule (3), closed by a closure device (39), with a needle holder (22). In the needle holder (22) a cannula (23) is mounted, directed towards the opened front side (12) of the receiving vesel (11), and projects in the direction thereof. A through-flow opening (53) is connected by means of a connecting canal (32), constructed between the needle bolder (22) and a front wall (17) of the receiving vessel (11), with a removal needle (5) of a needle arrangement (4), arranged eccentrically to a central longitudinal axis (13) of the receiving chamber (15). Between the connecting canal (32) and a receiving chamber (15) of the receiving vessel (11), an openable valve arrangement (52) is arranged as required. This valve arrangement (52) is formed fly a hose valve (36) or flap valve arranged between the cannula (23) and the receiving chamber (15) and/or the connecting canal (32). The cannula (23) is preferably arranged concentrically to the receiving vessel (11). A through-flow canal (31) opens between the cannula (23) and an outer wall of the receiving vessel (11) into the connecting canal (32).
