摘要：
The present invention relates to an intra-aortic dual balloon pump catheter device. The intra-aortic dual balloon pump comprises: a catheter (2)； a first balloon (4) and a second balloon (6) arranged to successively surrounding the catheter along the longitudinal direction of the catheter (2), wherein the position of the first balloon (4) is closer to a catheter end (5) of the catheter (2) than the position of the second balloon (6)； the first balloon (4) and the second balloon (6) are periodically expanded to a dimension that blocks the aortic blood flow and contracted to a dimension that does not prevent the blood flow from passing through； wherein the first balloon (4) begins and finishes the inflation earlier than the second balloon (6) in each period of expansion and contraction.
