A device for taking blood samples comprising a holder (1) for a blood sample tube (2), the holder (1) carrying a needle (3) and being mounted in a safety shield (4) in a way enabling its axial displacement relative to the shield (4) between a blood sample taking position, the point of the needle (3) projecting from the shield (4), and a protective position, the needle (3) being completely confined in the safety shield (4). The axial displacement of the holder (1) is obtained by means of a finger grip element (10) at the holder (1), this grip (10) being movable in a slot (11) in the shield (4). Fixing of the holder (1) in the end positions is obtained by using the same grip (10). The blood sample device may be provided with slot-formed openings in the shield, enabling the holding with the hand of the tube (2) during the blood sample taking, with a further holder for tubes (2) with smaller diameter, with an internal threaded bottom of the holder (1), enabling use of a separate needle and/or with a holder (1), which is activated by a spring. |
