Abstract
The blood taking device consists of a cylindrical tube with a rounded closed end. A sliding piston is positioned on a rod which has four lengthwise guide pins. The rod has a round hollow grip piece in which locates a connecting piece. The connecting piece has a bore leading to a channel in the piston. The piston has a disc at right angles to the piston. A collar ring has a permeable front piece. The ring part of the collar has a circumferential slot into which the front edge of the disc snaps. The outer edge of the ring part lies sealed, elastically pressed against the tube inner wall. The front part of the ring has a cross-slit with equally sized slits.
