ARRANGEMENT FOR EXTRACORPOREAL CIRCULATION OF BLOOD

摘要

Arrangement for extracorporeal circulation of blood having a genereally uniform flow diameter where the risk for stagnation of blood is avoided or reduced. The arrangement comprises a generally circular cylindrical means for temporary expanding the flow diameter, a means for flow expansion (9). The means for flow expansion (9) is arranged connecting the bloodline (5) and a component (6, 8) for circulation of the blood. The means for flow expansion (9) comprises a first part with a first flow diameter, dl and a second part downstream the first part with a second flow diameter d2 where d2/dl=l, 5. The first part has a length extension Ll and the second part has a length extension L2 where L2/Ll=0,5.
