Claims

[Scope of claim for utility model registration] An armpit-type simple control device used in conjunction with an electrocardiogram measuring device for intra-aortic balloon pumping IABP therapy to reduce the blood ejection burden for patients with heart disease, Two sets of roller pumps whose rotation can be stopped automatically are fitted with a balloon inserted into the patient's aorta that is freely inflated and inflated by liquid or gas, and an outlet and an inlet of a pressure chamber for liquid or gas as appropriate. one branched liquid or gas tube having a length of approximately 100 mm is connected to the outlet of the pressure chamber, and the other liquid or gas tube is connected to the inlet of the pressure chamber for communication;
The respective liquid or gas tubes are inserted between the curved surface of the respective roller pumps and the rollers in a state where they are difficult to move, and when one roller pump rotates and the other roller pump stops, the aorta is removed. Coronary blood volume can be increased by inflating the balloon inside, or conversely, by stopping one roller pump and rotating the other, the balloon can be deflated to facilitate ejection of the left ventricle. 1. A balloon drive device for intra-aortic balloon pumping therapy, characterized in that the expansion and contraction of the balloon can be freely controlled to reduce the burden on the heart.
