Venous cardiac assist device and interventional therapy equipment applying same

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a venous cardiac assist device and interventional therapy equipment applying the same. The venous cardiac assist device comprises a balloon catheter, a first balloon, a second balloon and a third balloon; when the device is used, the second balloon is controlled to be inflated to swell at the rightatrium; then the first balloon and the third balloon are controlled to be inflated to swell at the superior vena cava and the inferior vena cava respectively; afterwards, the second balloon is controlled to be deflated so as to form negative pressure in the right atrium; then the first balloon and the third balloon are controlled to be deflated. Accordingly, by means of the three balloons, and bycombining cooperation of the corresponding control timing sequence, the function of the right atrium can be effectively improved, the perfusing effect is improved, the microcirculation disturbance ishelped to be improved, the micro blood flow velocity is increased, the ischemia and hypoxia conditions are improved, microcirculation is well helped, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a venous heart assist device and interventional treatment equipment using the device. Background technique [0002] At present, intra-aortic balloon pump (IABP) is the earliest auxiliary circulation method based on the theory of oxygen supply and oxygen consumption. It was first used clinically in 1968. In the early stage, IABP was mainly used for circulatory support in patients with cardiac perioperative hemodynamic instability, cardiogenic shock or heart failure, and surgical incision of blood vessels was usually required to implant an intra-aortic balloon . The emergence of percutaneous puncture technology in the 1980s made IABP have the advantages of less trauma, less complications and easy operation. [0003] IABP is a device that uses the principle of "counterpulse" to run synchronously with the cardiac cycle of the heart, so as to increase the blood flow of the c...

Problems solved by technology

However, the above-mentioned balloon catheter device in the prior art often uses a balloon, and is only used in the perfusion field of coronary arteries

However, there are few applications for the coronary vein field, and the effect of the balloon catheter device in the prior art is not ideal when used.
