Claim:
1. A suction cup device for haemostatic control of bleeding in a tissue area during a haemorrhage or a bleeding episode, the suction cup device comprising: a hemispheric dome having an axis of rotation and an arcuate end and a peripheral edge at distal ends of the axis of the rotation such that the arcuate end and the peripheral edge are extremities of said dome along the axis of rotation, said dome comprising a bottom part at the arcuate end, an upper part at the peripheral edge, a height defined from the upper part to the bottom part along the axis of rotation, a diameter increasing from the bottom part to the upper part along the axis of rotation, an outer surface, and an inner surface, the inner surface at the peripheral edge configured to surround and be tightly applied onto said tissue area; a solid obturator integral with a center part of the bottom part of said dome and being shaped as a solid straight cylinder having as an axis the axis of rotation of said dome, a circumference, a solid end opposite the bottom part of the dome along the axis of said dome, and a height measured along the axis of said dome from the bottom part to the solid end of the cylinder, the obturator having a surface formed along the circumference and extending along the height of said obturator and the solid end, the height of said obturator being less than the height of said dome, the solid end being closer to the peripheral edge of the dome than the bottom part of the dome, the solid end being sufficiently close to the peripheral edge of said dome such that when the peripheral edge is positioned onto said tissue area having an open wound with lips forming edges of the wound and suction is applied to create a vacuum in the inner volume, the solid end exerts a compression force onto the lips so that the lips join together and maintain said tissue area in place at the upper part of said dome so as to allow haemostasis to be carried out on the tissue area; an inner volume delimited by the surface of the obturator and the inner surface of the dome from the obturator at the center part of the bottom part of the dome to the upper part at the peripheral edge, said inner volume being empty; a linking device positioned at the bottom part of said dome, said linking device configured to tightly link the inner volume of said dome to a catheter or a linking tube of an outer suction and vacuum creating device so that suction can be applied in the inner volume of said dome when the peripheral edge of the dome is positioned on said tissue area, to provide a depression in pressure in the inner volume surrounding the tissue area; and a through hole linking the inner volume of the dome between the inner surface and the solid obturator to said linking device, said through hole being located at (i) the bottom part of said dome proximate to the obturator and/or (ii) along the height of the cylinder of said solid obturator proximate to where the cylinder contacts the bottom part of said dome.
