Title (EN) BLOOD PUMP
(FR) POMPE SANGUINE
Abstract:
(EN) A blood pump (1) comprises a pump section (2) and a flow cannula (3). A proximal end portion (14) of the flow cannula (3) is connected to the pump section (2) such that blood can enter the blood flow inlet (11), and a distal end portion (13) of the flow cannula (3) includes at least one blood flow-through opening (16) for blood to enter the flow cannula (3). The distal end portion (13) comprises an enlarged diameter portion (15), with at least a major portion of the blood flow-through opening (16) being disposed in the enlarged diameter portion (15). The blood pump (1) further comprises a sleeve (4) overlapping the enlarged diameter portion (15). The sleeve (4) has a structure that prevents its distal end (42) from bending radially inwards into the blood flow- through openings (16).
(FR) La présente invention concerne une pompe sanguine (1) comportant une partie pompe (2) et une canule d'écoulement (3). Une partie d'extrémité proximale (14) de la canule d'écoulement (3) est raccordée à la partie pompe (2) de sorte que le sang puisse entrer dans l'entrée de flux sanguin (11), et une partie d'extrémité distale (13) de la canule d'écoulement (3) comprend au moins une ouverture d'écoulement sanguin (16) pour que le sang entre dans la canule d'écoulement (3). La partie d'extrémité distale (13) comprend une partie de diamètre élargi (15), avec au moins une grande partie de l'ouverture d'écoulement sanguin (16) disposée dans la partie de diamètre élargi (15). La pompe sanguine (1) comprend en outre un manchon (4) recouvrant la partie de diamètre élargi (15). Le manchon (4) présente une structure qui empêche son extrémité distale (42) de se plier radialement vers l'intérieur dans l'ouverture d'écoulement sanguin (16).
