A device for controlling blood flow occurring in a haemorrhagic zone of a biological tissue, includes a flexible plate arranged to be placed opposite this zone, the flexible plate including: substantially leaktight peripheral supporting elements, for applying on the tissue so that the zone is surrounded； a back wall delimiting, with the supporting elements, opposite the zone, a hollow space； connecting elements connecting the hollow space, externally to the flexible plate, to an external aspiration source for creating a vacuum in the hollow space for aspirating and tightly applying the surface of the tissue against the peripheral supporting elements； and a hollow stud placed between the zone and the back wall and hollowed out in its center on the side of the zone along an axis substantially perpendicular to the back wall, and arranged to be in contact with the zone when the vacuum is created in the space.
