Problems solved by technology

[0006] However, the existing disclosed technology still has the following three deficiencies: (1) The diameter of the balloon is usually 90%-95% of the diameter of the aorta, which cannot completely fix the IABP balloon catheter and achieve the function of completely blocking blood flow; (2) ) Increase the diastolic pressure and coronary blood flow of the left ventricle by expanding the balloon and changing the lumen area of ​​the systemic artery (partially blocking the blood flow), but it is impossible to further improve the coronary blood flow by providing external power; (3 ) Lack of real-time pressure sensing capability in the left ventricle or coronary artery, unable to adjust counterpulsation speed, counterpulsation pressure and perfusion flow in real time according to changes in treatment effects and body functions

Abstract

The invention provides an implantable intra-aortic pumping device with pressure sensing and automatic regulating functions. The implantable intra-aortic pumping device is composed of an active pressure regulating type pumping balloon with an optical fiber pressure sensor, and a pump. The active pressure regulating pumping balloon comprises an outer-layer fixed balloon, a power cavity, a blood cavity, an ascending catheter with an optical fiber pressure sensor, a double-cavity tube and the like. The power cavity is connected with the pump and is separated from the blood cavity by an elastic membrane, and the deformation state of the elastic membrane is influenced by the change of the pumping -out pressure of the pump so as to realize the adjustment of the pumping blood flow pressure. The blood cavity is connected with an ascending catheter, the optical fiber pressure sensor is arranged in the wall of the ascending catheter, and the functions of descending blood flow release, pressure sensing and signal transmission can be achieved. When the device works, the optical fiber pressure sensor collects coronary artery and / or left ventricle blood pressure data in real time and transmits the data to the pump. The pump dynamically adjusts the pumping-out pressure according to the obtained coronary artery / left ventricle data and transmits the pressure to the blood cavity through the power cavity, and automatic regulation and control of the pumping pressure are achieved. The implantable intra-aortic pumping device is an important improvement of a traditional intra-aortic pumping device, namely dynamic regulation and control of pumping pressure within a certain range are realized, and a larger operation space is provided for clinic; and coronary artery / ventricular blood pressure data are monitored in real time, a basis can be provided for clinical diagnosis and treatment, and the safety and effectiveness of intra-aortic pumping treatment are improved.

Description

technical field [0001] The invention relates to an implantable aortic anti-pulse device with the function of pressure sensing and automatic regulation, and relates to the technical field of interventional therapy. Background technique [0002] Aortic balloon pump (Intra-Aortic Balloon Pump, IABP) is an interventional treatment method for cardiovascular diseases. The process is to enter a guide wire through the femoral artery, treat the descending aorta and abdominal aorta, and implant A balloon that can be inflated and deflated is inserted, and the distal end of the guide wire is connected to a counterpulsation machine for regulation, detection, and driving of the balloon. The mechanism is that the air bag is inflated during diastole and deflated during systole, which can reduce the burden of systole, increase cardiac ejection, and increase coronary or aortic blood flow during diastole, thereby improving the blood supply of coronary artery or aorta. IABP can increase corona...
