The system (1) has a closure element (2) formed from a material with elastic properties. A pressure body (3) is formed at an opened vessel in a patient to apply pressure increased in relation to wide areas of the vessel to an injection location in the vessel. The pressure body is placed to apply the pressure reduced to the injection location on an aspiration location at a skin. The pressure body is placed to apply the reduced pressure to a region for pulse measurement at the vessel. The pressure body reproduces an anatomical form of a finger replica for manual closing of the vessel.
