Military Technology

Seeing everyone's puzzled expressions, Wu Hao introduced with a smile: "Actually, the artificial placenta can describe this active printing chamber very vividly, which is why it is named such a name.

Although the principles are basically similar, they are all spatial environments that nurture living tissues and organs, but they are also very different from each other.

These fluids that you see can be regarded as amniotic fluid in the placenta, which can maintain the activity of biological cells in the printed tissues and organs, and provide them with relevant nutrients, enabling them to survive longer in this simulated environment.

Of course, this is not enough. When printing some large tissues and organs, we have to print a biological circulation channel for it first, so as to connect the venous arterial vascular network of the eye organ, and connect ECMO (artificial lung) for blood circulation, Provide nutrients to the organs and tissues during the printing process to keep them alive at all times.

In addition, this technology can also be applied to a short-term preservation process after the organs are printed. Through this extracorporeal circulation technology, the printed organs and tissues can survive for a certain period of time.

Nonetheless, we recommend that these organs and tissues be transplanted as soon as possible once they are printed. The longer the delay in responsibility, the worse the biological activity of these organs and tissues, and the lower the success rate of transplantation, including the function of the organs and tissues after transplantation. "

What is this that is printing? Xu Shenghua asked Wu Hao.

Wu Hao looked at the technical expert who accompanied him, and the technical expert immediately introduced: "The actual human muscle tissue being printed in the printing chamber is mainly used to repair the human body caused by sports injuries or other accidental injuries. Muscles and tendons are damaged.”

Oh, after hearing the technical expert's introduction, everyone paid more attention and stared at the printing screen displayed on the big screen for a long time. Director Qi Feng pointed at Wu Hao and said with a smile: "Xiao Wu, it seems that you have been prepared for a long time. No wonder you came up with such a technical plan."

Wu Hao smiled and shook his head: "In fact, since the development stage of this biological 3D printer engineering machine, we have been conducting relevant functional tests on it. Today's printing project is just one of a series of tests. Of course. , After receiving the relevant task request, we immediately adjusted the direction of relevant experimental research, focusing on printing experiments on skin and muscle and nerve tissue."

Wu Hao is not lying, in fact they have been experimenting with printing muscle and tendon tissue and have made some progress. The reason for making breakthroughs in this field is that compared with other organs and tissues, muscle tissue and skin tissue are relatively simpler in structure, which is conducive to printing.

Of course, on the other hand, there is also a huge market in this area. Routine injuries aside, there is a huge patient population in this field. Let's just say that one of the top fields is the field of sports injury medicine, which is a very popular subject field.

You must know that we need to invest huge human, material and financial resources to train and train an excellent top athlete, and it may not be able to produce results. Often it is only a handful of top players in the entire huge team of athletes, maybe just a few people, or even one person.

They often have to go through more than ten years of day-to-day, uninterrupted training before they can achieve such little results and emerge in the international arena. But at the same time, injuries also plagued them.

This is the case with many top athletes. They had very good results and achieved very good results in international competitions, but because of injuries, they had to regret leaving the arena and choose to retire.

Many athletes were in good condition, and it was the time when they achieved results, but because of an accidental injury, they had to say goodbye to the arena. For example, the well-known basketball superstar Yao Ming, the 110-meter hurdles Liu Xiang, etc., all of them had to leave the game because of injuries, which brought wireless regrets.

In fact, medical experts are making concerted efforts in response to their conditions, and it can be said that there is a wave of the top people in the field of sports medicine in the world. But in the end, it was impossible to save their sports career and let these people leave with regret.

In fact, these are just some famous ones, and behind them there is a large group of obscure ordinary athletes who had to choose to retire because of injuries. Many good athlete seedlings may be an accident, so they have to say goodbye to their sports career. They have few outstanding achievements, and the most precious moments in their lives are in their favorite sports. Retirement with a whole body of injuries, many people may be helpless for the rest of their lives.

And if this technology is developed, it will save the careers of a large number of athletes, allowing them to say goodbye to their injuries and reappear on the field. In addition to athletes, there are also many patients from all walks of life, as well as many patients in society who have been injured by various accidents. This technology can also bring hope to them and allow them to return to normal people.

For Wu Hao and the others, while saving countless patients, they will also gain huge benefits. So many patients mean that this will be a huge market, representing unlimited money and power.

How about this technology now, has animal clinical trials been conducted? Zhang Qinghong asked Wu Hao.

Wu Hao nodded with a smile: "Of course, we have already carried out experiments on mice, rabbits, and pigs. From the current point of view, the experimental results are good. Next, we will test on macaques and orangutans.

After these test results come out and there are no problems~www.readwn.com~ we can apply for direct application to Zou Feifei. "

How long will this process take? Zou Feifei is still waiting on the hospital bed. Director Qi Feng asked Wu Hao a question, then sighed and said, "A lot of people have paid attention to this matter of Feifei Zou, and Feifei Zou is now updating the log on social accounts every day to record the treatment process, so It attracted a large number of netizens and media attention.

If the delay is too long, it is likely to cause doubts or even criticism from the public. "

Hearing Qi Feng's words, Xu Shenghua couldn't help but criticize with a dissatisfied expression: "Medical treatment and medical research are both prudent tasks and must be done with caution, there is no hurry.

No matter what kind of treatment method is needed, it will take time, and there is no rush, otherwise problems will occur. "

Wu Hao also smiled and nodded and said: "It will take at least two or three months. We have to give the experimental animals a recovery time and observe their recovery before we can know the experimental results. The muscle and nerve tissue transplanted into their bodies, including Is the skin tissue safe?"
