"Now I'm in good health, and I can also participate in some less strenuous sports." A year ago, Ms. Li from Dongxihu District, Wuhan City, Hubei Province, had a sudden outbreak of Myocarditis and heart failure. After implantation of domestic full magnetic suspension Artificial heart, Ms. Li can now live a normal life. Heart failure is the biggest challenge in the field of cardiovascular disease. Medical research shows that the 5-year mortality rate of heart failure is 50%; After entering the final stage, the one-year mortality rate reaches as high as 50%. Heart transplantation is the preferred treatment for end-stage heart failure, but heart donors are extremely scarce. To solve this problem, researchers put forward the concept of Artificial heart. Clinical experience shows that Artificial heart treatment has a significant effect, which can not only save lives, but also effectively improve the quality of life of patients. The blood pump is the core component of the Artificial heart. It draws blood from the heart, raises the pressure, and delivers it to the aorta, thus partially or completely replacing the blood supply function of the natural heart. After technological evolution, full magnetic suspension is considered to be the mainstream technology of international Artificial heart. According to Chen Chen, the founder and CEO of Tongxin Medical, compared with other technologies, the blood pump rotor of the full magnetic suspension Artificial heart can achieve zero mechanical friction when rotating only through the support of magnetic suspension technology, which can keep the blood flowing smoothly without destroying the blood, greatly reducing the probability of complications after Artificial heart implantation. However, the technology of full magnetic suspension Artificial heart has been monopolized by foreign companies for a long time. It has become Chen Chen's dream to develop a full magnetic suspension Artificial heart with independent intellectual property rights. According to reports, the size of the full magnetic suspension Artificial heart is equivalent to a table tennis ball. How to ensure the stable operation of the blood pump while reducing the volume of the blood pump is the main difficulty in developing the full magnetic suspension Artificial heart. At the same time, the production of Artificial heart involves hundreds of links, each of which must be completed with high quality. Chen Chen told reporters that to make a component called a "nose cone", it requires tens of thousands of precise polishing to ensure its surface is smooth and avoid dust adhesion. Through more than 10 years of technical breakthroughs, the team has overcome technical challenges that cover the entire product system. Full magnetic suspension Artificial heart involves cutting-edge technologies in many fields. To this end, Tongxin Medical has established a scientific research team with more than 200 members from different fields such as medicine, physics, machinery and electronics. Researchers have demonstrated their strengths and worked together to overcome various difficulties in the industrialization process. The breakthrough of Tongxin Medical cannot be achieved without the collaborative support of industry, academia, and research. Since 2009, Tongxin Medical has led cooperation with universities and research institutes such as Tsinghua University and Zhejiang University, receiving support from national key research and development plans and international cooperation projects of the Ministry of Science and Technology. In 2013, Tongxin Medical and Fuwai Hospital of the Chinese Academy of Medical Sciences carried out Animal testing. In June 2017, Fuwai Hospital successfully implanted the domestic magnetic suspension Artificial heart into three critically ill patients, creating a history of clinical application of this product. It is reported that nearly 40 hospitals nationwide have used domestic magnetic suspension Artificial heart. We are promoting the application of remote information management and artificial intelligence technology, improving the portability of external components, and striving to achieve implantable batteries. At the same time, we are integrating the supply chain, improving process levels, reducing costs, and making our products more beneficial
