Facing the expectations of everyone, Wu Hao smiled slightly and then preached.
According to statistics from the World Health Organization, about 20 million people die from various heart diseases every year in the world, 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 human life and health, and compared with other diseases, heart disease is more dangerous. If you do not receive timely treatment, you may lose your life.
For many severe heart diseases, in the end, there is basically no good solution except heart transplantation. Even if the heart transplantation is completed, it is actually very uncertain how long the patient can survive. Because of allogeneic transplantation technology
It has a big drawback, that is, rejection, which requires long-term medication. Therefore, this allogeneic heart transplant can only help patients prolong their lives, but it cannot truly cure it.
Currently, the longest recorded survival time of allogeneic heart transplant patients is thirty years, which is a remarkable number. But for many young, especially adolescent patients with severe heart disease, thirty years is really a long time.
Too short. And this is only the longest record. According to statistics, the average survival time of allogeneic heart transplantation is about twelve years. Depending on the individual differences of the patients, this time can be long or short.
For patients and their families who have spent a huge amount of money to complete the allogeneic heart transplant surgery, such a small amount of time is obviously not enough.
Moreover, after many patients complete allogeneic heart surgery and transplantation, their personal quality of life is actually not very high, far from the level of normal people. They can only maintain a basic normal life, such as some strenuous exercise, and even some stimulating activities.
The story will be far away from them.
For the vast majority of patients with heart disease, most of them do not have the resources or conditions to undergo a heart transplant. The cost of treatment can easily reach hundreds of thousands or millions. For each patient and family member,
For us, this is a very huge expenditure, not everyone can afford it. Moreover, the final result is uncertain, and we don’t know how long such a large expenditure will last.
It is possible that what will be exchanged in the end is a situation of no one with no money.
For many patients with severe heart disease, in addition to conventional surgeries, they are also equipped with artificial hearts. The so-called artificial heart cannot actually completely replace the heart. It can only replace part of the functions of the heart and perform blood circulation. Absolutely
Most artificial hearts are actually a magnetically suspended 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 being equipped with an artificial heart. The blood will flow smoothly in the blood vessels, so the pulse will not beat. The stethoscope has no heartbeat sound, and even if an electrocardiogram is performed, it will only be a straight line.
, no data is displayed.
This artificial heart is indeed a great invention. It has saved the lives of many patients. But it is not without its shortcomings. First, its flow rate is stable, so the blood flow rate it delivers is the same no matter what time it is.
.
This also means that patients who have been transplanted with artificial hearts cannot exercise strenuously or have excessive emotional reactions, and they even need to pay attention to their diet. Once they exercise intensely, have strong emotional reactions, or eat a little too much, other parts of the body will be affected.
Organs require a large amount of blood to work. The blood flow rate of the artificial heart is quantitative, so it may cause hypoxic damage to other organs. Moreover, long-term fixed flow rate will also lead to a series of cardiovascular diseases, and may even cause serious thrombosis.
Wait for the danger.
Of course, scientists discovered the shortcomings in this area, and then developed an artificial heart with a heartbeat and pulse. The different speeds of the magnetic levitation tension were used to simulate and realize the pulsating flow of the college, thereby generating a pulse. However, this kind of heart still does not exist.
The pulse generated by the heartbeat also has very regular ripples. Although some problems have been solved, most of them have not been improved.
Subsequently, scientists developed an intelligent artificial heart that can sense the intensity of the human body's exercise and match different blood flows. This technology has definitely improved a lot compared to before, but there are still many problems.
, and also has great limitations.
And all artificial hearts cannot actually cure the patient, they can only prolong the patient's life. And limited by factors such as materials, the service life of most artificial hearts is only five years. After five years, they need to be replaced, but this is not the case.
Not all patients who use artificial hearts can be replaced with new ones in time. Because of long-term implantation of artificial hearts, many patients no longer have the conditions for secondary implantation.
So for these patients, they can only wait quietly for the end of life. This is cruel, but it has to be faced, and no one can change it.
Wu Hao's words made the atmosphere at the scene a bit depressing. These are facts, but they are facts that no one is willing to face.
A more frightening fact is that almost all of us are surrounded by patients with this type of heart disease, and there are also relatives who have died due to heart disease. Therefore, everyone is always so powerless when facing this kind of illness and death.
So the more this happens, everyone is full of expectations for the smart bionic artificial heart mentioned by Wu Hao, and they don't know whether it can really solve this major disease that seriously threatens human life and health.
After a slight pause, controlling the rhythm and giving everyone at the scene time to react and anticipate, Wu Hao continued his sermon.
"Almost at the same time as our intelligent bionic electronic prosthetic eye project, we launched the intelligent bionic development project of 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 functionality compared to other organs, and it is also the easiest to be bionic in theory.
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 currently no such technology in the world?"
Wu Hao shook his head and said: "Of course not. In fact, relying on our current technological level, we can completely create a lifelike artificial heart. However, this kind of heart may not be suitable for implantation in the human body. The main reason is that it is limited by the material.
.On the one hand, the corrosion resistance, stability and reliability of these materials, and on the other hand, the service life.”
