"If we simply create an artificial heart, it will be no different from those products on the market. This is not what we want.

What we want is a technical product that can truly replace the heart function and allow patients to return to normal life. Patients no longer have to worry about disease. They can not only enjoy a normal life, but also enjoy the excitement brought by exercise, and can even try some extreme sports that ordinary people cannot try. "

So with this idea, our intelligent bionic artificial heart technology research project team immediately started the research work in this area.

Before the relevant research is officially launched, in our opinion, this should be a project that is not that difficult. But when we got involved, we discovered that the technology in this project was far from simple as we thought.

First of all, we rejected the traditional artificial heart using pumping technology. In our opinion, this technology has great limitations, so we do not decide to adopt it.

Since we want a bionic heart, can we bionic an artificial heart with the same structure as a real human heart? This artificial heart, like the real heart, also relies on contraction to promote blood flow, so that the patient's heartbeat and pulse can be achieved.

Of course, the heartbeat and pulse are not enough, and you must be able to adjust accordingly according to the different status of the transplanter. For example, when the transplant recipient is walking normally, the smart bionic artificial heart contracts normally. When the transplant recipient starts running or doing distance exercises, the smart bionic artificial heart also needs to be based on the transplanter’s exercise intensity and the blood oxygen of each organ. The demand is adjusted to increase the frequency of contraction and increase the blood supply to support the corresponding high-intensity exercise of the patient.

At the same time, when the transplanter calms down, such as lying down and resting, the intelligent bionic artificial heart must be able to detect the corresponding state and make targeted adjustments. Such as adjusting the number and amplitude of contractions, thereby reducing blood flow, so as to ensure that the transplant recipient's major organs return to normal, and will not continue to congestion and hyperactivity.

It's not enough just to consider the function, we have to consider the material. Since it is necessary to simulate the real heartbeat and contraction in a bionic, there are strict requirements on the material.

First of all, all materials that make up this intelligent bionic artificial heart must have the characteristics of good corrosion resistance, fatigue resistance, and good biocompatibility. Because these requirements determine the operating time of this intelligent bionic artificial heart in the transplant patient, and it is directly related to the life of the transplant patient.

Therefore, we must extend the working time of the intelligent bionic artificial heart in the human body as much as possible, which has extremely strict and even demanding requirements for materials.

In addition, it must have strong biocompatibility. Simply put, these materials must be compatible with the human body, and there must be no rejection or allergic reactions. After all, these materials have to exist in the patient's body for a long time, so once these reactions occur, it will seriously affect the patient's health.

Generally speaking, the materials with these elements are all metals, such as titanium metal, which is the most commonly used metal among human medical devices and medical devices, because titanium metal has the above conditions.

But titanium also has its own limitations, not all parts are suitable for this metal. In particular, this intelligent bionic artificial heart must simulate the beating and contraction of the real heart, so the material must have a certain degree of humanity and softness. Only in this way can the contraction be carried out.

The metal obviously does not have the conditions in this regard, and the only thing that meets it is the polymer composite material. It is also a polymer conforming material that combines the above elements.

The next step is energy supply. The smart bionic artificial heart certainly cannot provide energy support for relying on the human body like a real heart, so it still needs its own energy. In this regard, batteries are generally used as energy sources to drive the entire equipment, but the battery has a limited lifespan. If it takes a long time, it may need to be replaced. In this way, the patient must be re-operated, which will cause a great burden on the patient. And pain.

So can you choose a new energy source or a new battery to ensure that the battery does not need to be replaced for a long time, or even for a lifetime.

Some people may have already thought about whether to use the nuclear batteries currently used by humans in the exploration of the universe. The nuclear batteries have long-term discharge characteristics, so that they can meet the energy needs of the artificial heart and do not need to be recharged for life.

This idea is good, but nuclear batteries are not as good as everyone thinks. It also has a series of problems, such as radiation problems. Nuclear batteries use radioisotopes, which are radioactive. If they are placed in the human body, whether they cause harm to humans, and whether there are some potential safety hazards, this is worth considering.

In addition, the heart is so big, and the space that can be given to the battery is very small. It is obviously not realistic to plug a nuclear battery into such a small space. Even if it is plugged, the continuous battery power produced by such a small volume is very limited, and I am afraid that it cannot support the operation of this intelligent bionic artificial heart.

Finally, the decay period of radioactive isotopes is actually not as long as everyone thinks. Generally speaking, it is about one to two to twenty to thirty years. If it is really used, it will be a big problem to replace and deal with it.

Therefore, we still focus on the field of ordinary batteries. As we all know, our Haoyu Technology has always been at the international leading level in the field of battery technology. So can we develop a battery that meets the above requirements as the energy source to drive this smart bionic artificial heart? This will also be one of the major problems that our team will overcome.

After the introduction, Wu Hao took a sigh of relief and gave the audience some time for reaction and digestion, and then he continued.

"After we listed these problems and the related technologies to overcome ~ www.readwn.com ~ the entire team, including some well-informed executives in the company, were also dumbfounded.

This series of technical problems brought by this seemingly simple intelligent bionic artificial heart is something we have never thought of before.

If you continue this project, then the difficulties faced and the investment required are absolutely unprecedented.

Continue or give up? "

Wu Hao looked at everyone and said with a smile: "We chose to continue. This is a very difficult decision. Because in the eyes of many people, our project will not have results.

But I firmly believe that we will be able to succeed. On the one hand, because I have enough confidence in our scientific researchers, on the other hand, we have firm goals, because we know that once this technology is successfully developed, it will not only bring huge economic benefits, but more importantly. Can save countless lives.

Formally because of this belief, it gave us the courage to persevere. "
