A member of the CPPCC National Committee, China Aerospace Science and technology group hospital days before former president Li Hong told reporters, the hospital developed the “artificial heart” has been carried out.A large number of animal experiments are being tested in Chinese food and Drug Inspection Institute and Shandong testing center, is expected to “13th Five-Year” during the stage of clinical test.
Heart failure is known as the “last battlefield of heart disease”, which has a 5 – year mortality rate of 50%. According to statistical data, the incidence of heart failure in China is about 1% of the total population and more than 10 million patients. For patients with end-stage heart failure, transplantation of artificial heart is the most effective treatment in the case of limited natural heart donor. In some developed countries, the treatment program has been included in medical insurance. The reporter learned that artificial assisted heart is very precise. It must be strong enough to send blood to the whole body. It is also very gentle, and can’t break blood, causing hemolysis or thrombosis. In addition, it has the characteristics of small size, light weight, small power consumption and permanent work. At present, there is no formal approval of sales products in our country.
The first 18 is the birthplace of China’s aerospace servo technology. The researchers found that the core of the rocket servo system – the precise motor and the pump – is very similar to the principle of the artificial auxiliary heart. They worked with Taida International Cardiovascular Disease Hospital in Tianjin to design and create a “Space Center”. The bold use of pumps and magnetic levitation technology integration solution, make the rotating parts pump can not contact the inner wall of the rotation, not only can the blood to minimize damage, but also let the blood pump long-term duty, the artificial heart technology in China directly into the international most advanced third generation, the most critical the hemolysis index of NIH is less than 0.006mg/dl, reached the international advanced level.
In 2013, researchers implanted space heart into a sheep, and it survived for 120 days, creating the longest survival record of domestic animal implanted products. In October 2017, researchers carried out batch animal experiments on many sheep. At present, 6 experimental sheep survived for more than 100 days, the longest being 139 days, indicating that the products were constantly ripe and perfect, and they already had batch production conditions.
