Embodiment Construction

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] Example: such as figure 1 , 2 , 3, and 4, the aortic counterpulsation balloon catheter capable of step-by-step slow-release control in this embodiment includes a special-shaped balloon 1, a double-layer sheath tube 2 and a Y-shaped joint 3, and the above-mentioned special-shaped balloon 1 is in the form of a long strip shape, which includes a multi-segment filled spherical balloon 11 distributed successively along its length direction. It is connected with the above-mentioned Y-shaped joint 3 and communicated with one of the interfaces of the above-mentioned Y-shaped joint 3. One end of the inner tube 22 of the above-mentioned double-layer sheath tube 2 passes through the above-mentioned outer tube 21 and th...

Abstract

The invention relates to an aortic counterpulsation balloon catheter capable of stepwise slow-release control. The aortic counterpulsation balloon catheter comprises a special-shaped balloon, a double-layer sheath and a Y-shaped joint. The special-shaped balloon is in the shape of a long strip and includes a plurality of sections of balloon bodies distributed in the length direction of the special-shaped balloon in sequence continuously and in a ball shape after inflation. One end of an outer tube of the double-layer sheath is connected to and communicates with the proximal end of the special-shaped balloon, the other end of the outer tube of the double-layer sheath is connected with the Y-shaped joint and communicates with one of connecting openings of the Y-shaped joint, one end of an inner tube of the double-layer sheath penetrates through the outer tube and the inside of the special-shaped balloon in turn and penetrates out through the distal end of the special-shaped balloon, anda flexible injection soft tip is arranged at the end of the inner tube, and the other end of the inner tube communicates with another connecting opening through the inside of the Y-shaped joint. The aortic counterpulsation balloon catheter has the advantages that when the balloon catheter is inflated and deflated, an interaction force can be generated through the non-synchronized phase differencebetween the distal and proximal ends of the inflation-deflation, the acting force can be used to provide greater kinetic energy, so that the energy load required by myocardial contraction is greatly reduced, and the auxiliary treatment effect is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an aortic counterpulsation balloon catheter capable of step-by-step slow-release control. Background technique [0002] Intra-aortic balloon pump (IABP: Intra-Aortic Balloon Pump) is a common method of mechanical circulation assistance. A catheter with a balloon is implanted through the arterial system to the distal end of the opening of the left subclavian artery and the opening of the renal artery. In the upper descending aorta, the balloon is inflated during diastole to increase coronary perfusion; before systole, the balloon is deflated to reduce cardiac afterload and achieve the effect of cardiac assistance. [0003] Inflation Timing: Begin inflation slightly before diastole. The goal of inflation: to generate high arterial diastolic pressure, thereby increasing the perfusion of coronary arteries; the timing of deflation: during the isovolumic systole, the deflation...
