Who can use the "artificial heart" listing independently developed by my country?Is this things reliable?

How far do you think "artificial heart" is from our lives?

Recently, the Drug Administration of our country has released a message, which has a "implantation left ventricular auxiliary system" approval to be available, and this kind of thing can be used.

But for ordinary people, from the name, it seems that I can't understand what this thing is used, as if it is related to the heart.

In fact, it is a very good left ventricular auxiliary system that can help the left ventricular work normally.

But what's the use of the left ventricle? Why do you need to work with help?

This question is very good to answer. The left ventricle is actually the most important place in the heart. You can pop the blood out of the heart and transport nutrients and nutrients to various organs and even cells in the body.

In other words, this auxiliary system helps to work, which will increase the ejection score.

To put it easier, this device with a very long name is actually a kind of:

"Artificial heart".

But who can this device use? Is there a manual heart in the future world?

First, the gospel of patients with heart failure.

How important is the heart, but you can imagine that some people have limited heart function due to various diseases, and the heart has no way to continue to supply blood for the body?

What should I do if this situation occurs?

In a person's life, the cells of our bodies are continuing to decline. This situation not only occurs in the heart, but also may occur in the brain and even the liver. Even the skin on the body surface is difficult to escape.

For most people, the decline of all the organs of this body can be referred to as two words:

senescence.

Who can escape aging?

The heart is like the heart, and the heart is beating every moment. If the heart stops working, the life of that person will last for a few minutes.

It is true that the heart will be aging. If the heart is really aging, its original ejection ability has gradually diminished, and it is not enough to supply blood to all cells of the whole body. What should I do?

This situation is not uncommon. In clinical practice, we call this situation as heart failure. If it is more comprehensive, his name is called:

Heart failure.

According to statistics from scholars, the number of patients who fail to fail globally has even reached 64 million, and the population of the world is gradually aging, and the number of patients with heart failure is rising.

If a person's heart really can't jump, what can we help him?

At the beginning, some people thought very simple and rude:

Change a heart.

We often see such a plot in science fiction works, but in fact, even in real life, it is not impossible to change a heart. We call this treatment for heart transplantation.

For a long time, for patients with heart failure in the end, heart transplantation is a very effective way. It sounds very simple and rude.

However, it is not so simple to change a heart. According to the current data, 91%of patients can live for a year after changing their hearts, but if they continue to live, the survival rate of patients is not so high.

Even if a full set of anti -rejection drugs are applied, 85%can live to three years, and only 75%of those who can live for another 5 years after surgery.

Of course, the survival rate is on the one hand, and on the other hand, the more severe problem is that we do not have so many hearts that can be used for transplantation. Not only in our country, even in the world, the lack of cardiac transplanted donor is obvious to all.

There are only less than 3%of patients with heart failure every year.

On the one hand, there are fewer donors, and on the other hand, the survival rate is not so high after transplantation.

What should I do?

Researchers will not stagnate, they will persevere in the way, and many people set their sights on another heart:

Mechanical heart.

Second, "mechanical heart".

Although we call it a mechanical heart, the relevant practitioners are not called that, but called him a more professional name:

Plant -type ventricular auxiliary device.

It is this artificial heart that can replace the left ventricle to help the heart ejaculate and restore the aging heart to recover vitality.

Moreover, this artificial heart is not a sudden imagination.

As early as the 1950s, many scholars have begun to explore this. Around 1970, many countries have already listed similar devices to help patients with heart failure in the final stage.

There are many types of artificial hearts, some of which help the left ventricular beating, and some help the right ventricle beating. Of course, there are rare devices that can help the two ventricles jump together at the same time.

In addition, according to the different blood flow pumps, the device is divided into many types, such as: fighting blood flow type, continuous blood flow, and even suspended type. This time, the artificial heart with independent intellectual property is listed on our country, which is a floating system.

As early as 1964, some scholars in the United States opened an artificial heart plan. In 1969, they used this device for the first time, but the technology at that time was not mature. This auxiliary system could not continue to work. A substitute. After 64 hours of life, the patient's life was replaced with the heart of the supply.

Until 1992, the dual -ventricular an auxiliary system developed by a US company was officially launched. After that, for many ventricular dysfunction and myocardial infarction patients, the temporary new -style auxiliary has officially appeared on the stage, and more and more patients benefited from this technology. However, in addition to the United States for so many years, there are also some Japanese EU countries participating, but there are not many new -style auxiliary devices in our country.

It was not until 2019 that Chongqing Yongrenxin Enterprise only produced a planting left ventricular auxiliary system. From then on, our country has officially possessed its own artificial heart.

The left ventricular auxiliary system that was listed this time was named "Rocket Heart". This device uses magnetic liquid suspension technology, which can play a role in the left ventricle. More importantly, my country has a complete autonomous intellectual property rights of this device.

Summarize.

Although it is just a small report, it is undeniable that the development of our country in science and technology can be described as changing with each other, and more and more independent intellectual property equipment is being developed.

The artificial heart released this time is very important for the end -stage treatment of patients with heart failure. These patients may not have to wait for the emergence of heart transplants.

It is believed that there are more and more similar research, and many artificial organs will gradually appear on the stage, and more and more health problems can be resolved.
