Embodiment 1
[0028] combine Figure 1 to Figure 3 As shown, the present embodiment provides a venous cardiac assist device, which includes: a balloon catheter 7, a first balloon 2, a second balloon 4 and a third balloon 6; the distal end of the balloon catheter 7 passes through the Sleeved on the first balloon 2, the second balloon 4 and the third balloon 6, it can be understood that the first balloon 2, the second balloon 4 and the third balloon 6 are sequentially arranged on the balloon Of course, the distance between the balloons at the distal end of the catheter 7 can be flexibly set according to actual needs. Similarly, the size of each balloon can also be specified according to different situations, which is no longer limited here. Wherein, preferably, the maximum expansion volumes of the first balloon 2 and the third balloon 6 are both smaller than the maximum expansion volume of the second balloon 4 . Moreover, the first balloon 2 , the second balloon 4 and the third balloon 6 are...
