摘要：
The invention relates to a radial blood pump (1) for supporting a blood flow (106) in a human or animal heart (205) comprising a first and a second inlet channel (41, 42), a first outlet channel (51, 52), a first electric motor (71) comprising a first stator (77) and a first internal rotor (75), wherein the first electric motor (71) is configured to drive an impeller (2, 2a, 2b) arranged at an intersection of the first with the second inlet channel (41, 42), wherein the impeller (2, 2a, 2b) is connected to the first internal rotor (75) and wherein the impeller (2, 2a, 2b) comprises a merging portion (22) arranged at the intersection, where a merging of a first blood flow (106) coming from the first inlet channel (41) and a second blood flow (107) coming from the second inlet channel (42) takes place, wherein the impeller (2, 2a, 2b) is configured to pump the first and second blood flow (106, 107) from the first and second inlet channel (41, 42) via the merging portion (22) to the first outlet channel (51), a plurality of blades (20) comprised by the impeller (2, 2a, 2b), wherein the blades (20) form blade channels (21) comprised by the merging portion (22), wherein each blade (20) is arranged and configured to pump the first and second blood (106, 107) flow entering through the first and the second inlet channel (41, 42) towards the outlet channel (51), wherein the blood pump (1) is arranged and configured such that the first blood flow (106) and the second blood flow (107) meet at the merging portion (22), such that a pressure difference between the first and second blood flow (106, 107) is reduced before blood from first and second blood flow (106, 107) is pumped to the first outlet channel (51).L'invention concerne une pompe à sang radiale (1) pour supporter un flux sanguin (106) dans un cœur humain ou animal (205) comprenant un premier et un deuxième canal d'entrée (41, 42), un premier canal de sortie (51, 52), un premier moteur électrique (71) comprenant un pre
