Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Figs 1-4, a kind of aid blood circulation device for heart failure includes the blood for extracting blood in heart
Liquid suction tube 100 extracts blood in heart for the counterpulsation sacculus mechanism 200 of aorta counterpulsation, for passing through blood suction tube 100
The blood drawing pump 400 of liquid, the control mechanism of control loop device work；The blood suction tube 100 connects with counterpulsation sacculus mechanism 200
It connects, blood efferent duct 300 is connected between counterpulsation sacculus mechanism 200 and blood drawing pump 400, it is defeated that blood drawing pump 400 is also associated with blood
Enter pipe 500.
As shown in Figure 1, 2, in the aid blood circulation device for heart failure, 100 main function of blood suction tube
It is inserted into heart left ventricle, the blood of left ventricle is pumped out, due to being put into left ventricle, then the preferably described blood suction
Pipe 100 is at least soft, situation that there are two types of this structures：A kind of is only soft, i.e., the described blood suction tube in front end
100 front ends are soft conductor housing, and the soft conductor housing is curly, and its side is provided with the tube chamber with blood suction tube 100
The suction hole 101 of unicom；Another kind is that entire blood suction tube 100 is soft, i.e., the described blood suction tube 100 is soft
Pipe, the soft tube are curly, and front end side is provided with the suction hole 101 with the tube chamber unicom of blood suction tube 100.
Using soft conductor housing or soft tube as blood suction tube 100, avoid the head end using hard material in blood
In suction, it is placed in improper or unexpected the problems such as causing aorta wall disease, the even stripping on cardiac endothelial surface, is also avoided
Cause the damage of aorta wall.And curly form also complies with left ventricle internal structure, due to cannot directly be placed in left ventricle
The blood suction tube 100 of long size, but in order to enough smooth suction bloods, then the blood that must place sufficient length is taken out
