Problems solved by technology

But the disadvantage of this design is that the device structure is too complicated
The switch between the positive pressure control motor and the negative pressure control motor is difficult to accurately control, and the gas circuit detection method is complicated, the structure is unstable, and the structure cannot be simple and the control is efficient.

Abstract

The invention belongs to the technical field of internal counterpulsation equipment, in particular to a structured gas circuit system suitable for an intra-aortic balloon counterpulsation pump, including an inner balloon, a helium cylinder, and an inflation and deflation unit; The air unit includes a bellows, a drive motor and a bellows. The drive motor is arranged outside the bellows, and its output shaft passes through the box plate of the bellows and extends into the accommodating space of the bellows, and at the end of the output shaft There is a threaded rod, one end of the bellows is against the first box plate of the bellows, and a bearing is fixed at the other end, the bearing is sleeved on the screw rod, and when the driving motor drives the screw rod to rotate, the bearing Drive the end of the bellows to move to compress the gas inside or generate negative pressure; in the specific use process of the present invention, first fill the inner balloon with a certain pressure of gas, and then drive the bellows through the drive motor Apply and release pressure to the air circuit structure, so as to achieve the therapeutic effect of counterpulsation.

Description

technical field [0001] The invention belongs to the technical field of internal counterpulsation equipment, in particular to a structured gas circuit system suitable for an intra-aortic balloon counterpulsation pump. Background technique [0002] The intra-aortic balloon counterpulsation pump is to place a special balloon catheter in the artery, controlled by the electronic and air source system, so that the balloon is inflated during the diastolic period and deflated during the systolic period, so that the diastolic pressure in the aorta increases , systolic blood pressure decreased, so as to achieve the purpose of increasing coronary blood supply and reducing cardiac afterload. [0003] In order to provide the required gas pressure for the balloon, for example, a dual-motor motor design provided in the prior art adopts the method of positive and negative pressure gas-driven control structure, that is, a certain positive pressure is formed in the cylinder through the rotati...
