Vol 2 Chapter 1576: Smart bionic artificial heart

Facing everyone's expectations, Wu Hao smiled slightly, and then preached.

According to the statistics of the World Health Organization, there are about 20 million people die from various heart diseases in the world every year, and more than 5 million people die from various heart diseases in our country every year.

It can be said that heart disease has become a major killer of the impression of human life and health, and compared with other diseases, heart disease is more dangerous. If you don't get medical treatment in time, you may lose your life.

For many severe heart diseases, in the end, there is basically no good way except for heart transplantation. Even after a heart transplant is completed, how long the patient can survive is actually very uncertain. Because allograft technology has a big drawback, that is, rejection reaction, which requires long-term drug maintenance. Therefore, this kind of allogeneic heart transplantation can only help patients to prolong their lives, and cannot be a real cure.

At present, the longest recorded survival period of allogeneic heart transplant patients can reach up to 30 years, which is a very remarkable number. But for many young people, especially adolescents with severe heart disease, thirty years is too short. And this is only the longest record. According to statistics, the average survival period of allograft heart transplantation is about twelve years. According to the individual differences of patients, this time is long and short.

For the patients and their families who have spent a huge price to complete the allogeneic heart transplantation, such a little time is obviously not enough.

Moreover, after many patients have completed allogeneic heart surgery, their personal quality of life is actually not very high, far below the level of normal people. They can only maintain a basic normal life, like some intense sports, even some stimulating activities and even stories will stay away from them.

For the vast majority of heart disease patients, most of them do not have the resources and conditions to perform heart transplants. The treatment cost of hundreds of thousands of millions is a very huge expense for every patient and family member, and not everyone can afford it. And the final result is uncertain, and I don't know how long such a large expenditure can be exchanged for.

It is possible that in the end, there will be two situations where no one has money.

For many patients with severe heart disease, in addition to conventional operations, there is also an artificial heart for them. The so-called artificial heart, in fact, cannot completely replace the heart, but can only replace part of the heart's functions and carry out blood circulation. Most of the artificial heart is actually a magnetic levitation axial flow pump, which uses the pumping principle to replace the heart for blood circulation.

Because of this, many heart disease patients lose their pulse after installing artificial hearts. The blood will flow smoothly in the blood vessels, so the pulse will not beat. There is no heartbeat in the stethoscope, even if it is an electrocardiogram, it is just a straight line without any data to show.

This artificial heart is indeed a great invention, and it has saved and continued the lives of many patients. But it is not without its shortcomings. First of all, its flow rate is stable, so the blood flow rate it delivers is the same no matter what.

This also means that patients undergoing artificial heart transplantation cannot exercise vigorously, have excessive emotional reactions, and even need to pay attention to their diet and so on. Once the exercise is intense, the emotional reaction is strong, or if you eat a little too much, other organs of the body need a lot of blood to work. The blood flow rate of the artificial heart is quantitative, so it may cause hypoxia damage to other organs. Moreover, a long-term fixed flow rate will also lead to a series of cardiovascular diseases, and may even cause serious thrombosis and other dangers.

Of course, scientists discovered the shortcomings in this area, and then developed the kind of artificial heart with a heartbeat pulse. The pulse flow of the college is simulated and realized through the different rotation speeds of the magnetic suspension, thereby generating the pulse. However, there is still no heartbeat, and the pulse generated is also a very regular ripple. Although some problems have been solved, most of them have not been improved.

Scientists then developed an intelligent artificial heart that can feel the intensity of the human body's exercise to match the different flow of blood. This technology is definitely a lot better than before, but there are still many problems, and there are also great limitations.

In fact, all artificial hearts cannot cure the patient, but can only extend the life of the patient. And limited by factors such as materials, the service life of most artificial hearts is only five years. It needs to be replaced after five years, but not all patients who use artificial hearts can be replaced with a new heart in time. Because of the long-term implantation of artificial hearts, many patients no longer have the conditions for secondary implantation.

So for these patients, they can only wait peacefully for the end of their lives. This is cruel, but I have to face it, and everyone is powerless to change it.

Wu Hao's remarks made the atmosphere at the scene a bit depressing. These are facts, but they are facts that no one wants to face.

A more frightening fact is that almost all of us will have this type of heart disease around us, and there will also be relatives who have died due to heart disease. So when everyone faces this kind of birth, old age, sickness and death, they are always so powerless.

So the more so, everyone is full of expectations for this intelligent bionic artificial heart that Wu Hao said~www.readwn.com~ I don't know if it can really solve this major disease that seriously endangers human life and health.

After a slight pause, he controlled the rhythm and gave everyone a reaction and expectation time. Wu Hao then proceeded to preach.

"Almost at the same time as our intelligent bionic electronic eye project, we launched the intelligent bionic development project for human organs, and the intelligent bionic artificial heart is the top priority of our entire project.

In our opinion, the human heart structure is the simplest in terms of structure and function compared to other organs, and theoretically the easiest to be bionic.

But so far, it seems that no artificial bionic heart has appeared in the world and can be successfully put into clinical treatment. Why, is it because there is no such technology in the world? "

Wu Hao shook his head and said, "Of course not. In fact, relying on our current level of technology, it is possible to create a sufficiently realistic artificial heart in bionics. However, this kind of heart may not be suitable for implantation in the human body. The main reason is still limited by the material. On the one hand, the corrosion resistance, stability, and reliability of these materials, on the other hand, is the service life."
