A pump-inflow-cannula, a pump-outflow-cannula and a blood managing system

摘要

The invention relates to a pump-inflow-cannula (1) providing a blood conduit from a heart (2) and / or from an associated vessel to an external blood handling system. Said pump-inflow-cannula comprises a body (3), encompassing an essentially axially extending inflow-lumen (4), having a distal-end (5) for an attachment of the inflow-lumen (4) to said blood handling system, and having a proximal-end (6) for an introduction of blood from the heart (2) and /or from the associated vessel into the inflow-lumen (4), wherein at least one projection (7) is provided at the proximal-end (6) to deflect a heart muscle from intruding into the inflow-lumen (4), wherein said body (3) of the pump-inflow-cannula comprises a reinforcement-means (8). The invention is also related to a pump-outflow-cannula (19) and to a blood managing system comprising a pump-inflow-cannula and a pump-outflow-cannula in accordance with the present invention.
