Abstract:
A left ventricle assist device, comprising: an outer tube (12) comprising a ventricle segment in the left ventricle and an artery segment in an aorta, first suction meshes (125) being provided on the ventricle segment, first discharge meshes (121) being provided on the artery segment, and the outer tube (12) communicating with an external drive device; a suction component at the ventricle side disposed within the ventricle segment; a discharge segment balloon tube (14) with two ends hermetically and fixedly sleeved on the outer wall of the artery segment, second discharge meshes (141) being provided on the discharge segment balloon tube (14), and the second discharge meshes (141) being offset from and not overlapping with the first discharge meshes (121). In the left ventricle assist device, by means of suction and pushing of the external drive device, the suction component at the ventricle side suctions blood from the left ventricle into the outer tube (12), and the discharge segment balloon tube (14) discharges the blood from the outer tube (12) into the aorta, completing a cycle and pumping blood from the left ventricle into the aorta. The left ventricle assist device has a simple structure and good reliability, reduces trauma to body tissues, and does not damage blood cells.
