For convenient insertion of a vacuum tube into the holder, the base of the cone is provided with an outer ring (finger stops), the plane of which is perpendicular to the holder axis. The holder with a cap is intended for use together with a tube for vacuum blood sampling and a double-sided needle for vacuum blood sampling of the patient.
