Everything about Dr. Tang: what is the real Chinese artificial heart like?

lately 《 Everything about Dr. Tang 》 It's on the air , Tang Jiayu, a female surgeon starring Qin LAN , Parachute Beijing Anhe Jisheng hospital to set up a heart center , I don't know Ouyang Zhenyu, the medical director , And ye Yi, an anesthesiologist starring Wei daxun

Ming gradually developed into a bosom friend . meanwhile , She led five members of the serious illness group : Qin Dazhong 、 Long Xiangdong 、 Zhou Da 、 Liao Xiaobo 、 Jiang Bailie treated them together 28 A rare heart case , And successfully developed domestic “ Artificial heart ”, Rewriting the history of China outside the heart , Finally realize self redemption , Harvest a happy life .

Artificial heart and heart transplantation are effective treatments for severe heart failure . data display 1, Our country has at least 1300 Ten thousand heart failure patients , It's one of the largest heart failure patient groups in the world . however , Fewer donors for heart transplantation , There are only 500 Multiple heart transplants . In the play , In order to keep patients from waiting for a heart transplant donor , Determined to develop artificial heart . in fact , In our country , At present, there are two artificial heart products on the market , They are yongrenxin EVAHEART And concentric CH-VAD. In addition, there is a space Taixin in research . These three products are the latest non-contact third-generation centrifugal pumps . But different technologies are used ,, Yongrenxin uses hydraulic suspension introduced from Japan （Hydrodynamic levitation）, Concentric adopts domestic self-developed magnetic suspension （Magnetic levitation）, Aerospace Taixin adopts the domestic self-developed magnetic fluid hybrid suspension （Magnetic levitation and hydrodynamic）.

  Different technology maturity and security are different , The indications obtained are also different . Yongrenxin is the only product with dual indications of long-term assistance and short-term assistance , Tongxin obtains short-term auxiliary indications . Rocket heart is still applying for approval .

EVAHEART ( Yongrenxin artificial heart ) It is currently the only artificial heart approved for long-term assistance in China . Yongrenxin artificial heart is made by yongrenxin medical and Japan HILEX The group jointly develops and produces , It has been approved in both China and Japan , At the same time, it also achieved the United States IDE Licensing and EU CE authentication . Yongrenxin adopts hydraulic suspension technology , At present abroad EVAHEART The longest assisted patient has used 11 year . The longest survival time of patients in China has reached 5 About years ago , Clinical trial patients after surgery 1 The annual survival rate is 100%. It is worth mentioning that , Yongrenxin artificial heart can produce up to 20-30mmHg Pulse pressure difference , The patient can produce a pulse , It has changed the dilemma of other artificial hearts without pulse .

  Tongxin is the second listed artificial heart in China , Adopt the magnetic levitation technology developed in Suzhou , stay 2021 year 11 On the listed , Suitable for short-term assistance ; Clinical trials 1 Annual survival rate 92%, The results of clinical trials show that ,CH-VAD In blood compatibility 、 Surgery is invasive 、 Anti infectivity 、 System reliability 、 Usability 、 Portability and so on VAD Performance indicators show advantages .

The artificial heart of aerospace Taixin has not been approved , But clinical trials have been completed . Aerospace Taixin adopts the magnetic fluid suspension technology developed by Tianjin Taixin , The volume is smaller than concentric , After a lot of animal experiments and tests , Currently, it is under application .

from 2019 The first yongrenxin third generation artificial heart was approved in , To 2022 Research and development of several artificial hearts in , For years , Domestic artificial heart gradually fills the gap in the field , For the majority of patients with heart failure to bring a new life . Those warm and touching medical plots , It is getting closer and closer to each of us . hope 《 Everything about Dr. Tang 》 After the broadcast , It can make more audiences pay attention to the prevention and treatment of cardiovascular diseases , From the precious and fragile heart , Realize the value of life .
