The present invention relates to a device for controlling a blood flow produced in a hemorrhagic area (4) of biological tissue (8), including a flexible plate (2) that is arranged so as to be placed opposite said area (4) and includes: a substantially sealed peripheral bearing means (3) capable of being applied onto the biological tissue (8) while surrounding the hemorrhagic area a bottom wall (5) that defines, together with the bearing means (3), a hollow space (6) opposite the area (4) a connection means (14, 15) arranged so as to connect the hollow space (6), outside the flexible plate (2), to an outer suction source so as to create, within the hollow space (6), a vacuum for suctioning and tightly applying the surface (7) of the tissue (8) against the peripheral bearing means (3) and a hollow contact pad (11) which is placed between the area (4) and the bottom wall (5), which has a recess in the center thereof on the area (4) side and along an axis (10) substantially perpendicular to the bottom wall, and which is arranged so as to be in contact with the area (4) when the vacuum is created in the space (6).
