主权项

1. A blood cassette comprising:
a clot trap including a screen surface for collecting clots in a blood flowing through the screen surface, the screen surface configured in the shape of a disc; and a cover means; wherein the screen surface is arranged such that an inflow of the blood is directed in a tangential direction substantially parallel to a main plane of extension of the screen surface; wherein the screen surface is substantially parallel to the cover means, wherein the blood enters into the clot trap through an inflow region and exits from the clot trap at an outflow region, the inflow region and the outflow region disposed on opposite sides of the clot trap, wherein the screen surface comprises at least one first portion having a plurality of segments of passage openings and at least one second portion without passage openings, wherein the at least one first portion at least one of faces or is adjacent to the inflow region, and the at least one second portion at least one of faces or is adjacent to the outflow region, wherein a distance between adjacent segments of the plurality of segments is smaller than a distance defining the at least one second portion.
