Device for haemostatic control of a blood flow, comprising a suction cup which provides leaktight coverage and is able to surround and be applied tightly to a tissue area (2) that is to be treated, said tissue area (2) being the site of a haemorrhage or of a blood flow that is to be controlled, this suction cup (3) coming into contact with the periphery of the tissue area and delimiting an internal volume (8) which is connected in a leaktight manner, by a catheter or a similar connecting tube (7), to an external aspiration element that establishes a vacuum, so as to create an underpressure of defined value within this volume between the suction cup and the tissue area, the suction cup (3) having the general shape of a dome (4), of which the base (5) supports an inner bearing element (11) that can be arranged opposite the tissue area (2) under the suction cup (3). The invention lies in the inner bearing element being formed by a solid obturator (11) or an open grill (13).
Dispositif de contrôle hémostatique d'un écoulement sanguin, comportant une ventouse de recouvrement étanche, apte à entourer et à s'appliquer étroitement contre une zone de tissu (2) à traiter, siège d'une hémorragie ou d'un écoulement sanguin à contrôler, cette ventouse (3) venant en contact avec la périphérie de la zone de tissu et délimitant un volume interne (8) relié de façon étanche par un cathéter ou un tube de liaison similaire (7) à un organe extérieur d'aspiration et de mise sous vide, créant dans ce volume, entre la ventouse et la zone de tissu, une dépression de valeur déterminée, la ventouse (3) présentant une forme générale de coupelle (4), dont le fond (5) supporte un organe d'appui interne (11) apte à venir se disposer en regard de la zone de tissu (2) sous la ventouse (3). L'invention consiste à former l'organe d'appui interne par un obturateur plein (11) ou une grille perforée (13).
