Description
the technical field is as follows:
the utility model relates to a heart assisted cycle field specifically relates to a pulsation formula pipe device of supplementary left ventricle function.
Background art:
Heart failure is a disease seriously threatening human life, about 1/5 heart disease patients can finally develop into heart failure every year all over the world, the heart failure incidence rate in China reaches 0.9 percent and the death rate in 5 years exceeds 60 percent at present. When the traditional medical treatment has certain limitations and can not achieve satisfactory curative effect, and the heart transplantation is difficult due to donor deficiency, postoperative rejection and the like, researchers propose a method for helping the heart to recover by using a mechanical device and develop a ventricular assist device. Since the clinical application in the 60's last century, through years of research and clinical application, the application of ventricular assist devices has expanded from resuscitation after cardiovascular surgery, transition or replacement of heart transplantation, to restoration of myocardial function and even permanent treatment of heart failure. The ventricular assist device can be used as a bridge for transition before heart transplantation and also used as a flat boat leading to myocardial recovery to improve the life quality of heart failure patients and be used for treating the heart failure patients.
the ventricular assist device is the most effective treatment method for various end-stage heart failure recognized all over the world. The development of the first generation pneumatic blood pump and the second generation axial flow blood pump in the 60 th generation of the world to the third generation suspension blood pump of today goes through the difficult research course of several scientists. The study on the ventricular assist device is carried out in the beginning of the last 80 th century in China, although the study is made by several generations of people, the study has a larger gap compared with the study made by foreign countries, and no commercialized domestic heart assist device is provided for clinical application so far. Although commercial ventricular assist devices exist abroad, the price of one device is as high as 50-100 ten thousand yuan RMB, but the price of one device is high. Therefore, it is urgent to develop a new home-made ventricular assist device with excellent performance and low cost. The first implantable ventricular assist device and the third ventricular assist device in China are successfully developed by the cooperation of Chinese engineering teams and medical teams, the longest survival record of the domestic implanted third ventricular assist device is created by animal experiments, and the development of the third ventricular assist device in China makes a major breakthrough.
however, the domestic third generation ventricular assist device is implantable and non-pulsatile, which not only needs to be implanted by a surgical operation to cause a large wound, but also does not accord with the physiological characteristics of pulsatile self of a human body. The device is implanted in a minimally invasive mode, the pulsating characteristic of the heart is continuously kept, and the direction of blood flow emitted into the aorta is consistent with the direction of blood flow emitted by the heart, so that the ventricular assist efficiency of the device is further improved.
