Chapter 276 If foreign countries can do it, why can't we?

The problem of money is not the most fatal.

The key lies in equipment and technology.

The preparation technology alone includes biological coating, electrospinning, tissue engineering, etc.

And moving artificial blood vessels from theory to reality involves more than a dozen processes.

From inoculating seed cells in the material scaffold, to constructing morphology and function, and finally implanting and decellularization, precision equipment and instruments are required, and there are technical barriers that are difficult to break through.

Including the test after successful preparation, artificial blood vessel pressurized burst strength tester, special tensile testing machine, etc. are also needed.

These equipment are also monopolized. What Daxia can get are basically products eliminated abroad and more than ten years ago.

Just like decades ago, today's Daxia scientists, doctors and scholars are also struggling under many blockades.

However, even the equipment from more than ten years ago is priceless. At present, only a few places such as Fuwai, Nankai Institute and Hubei Vascular Center are equipped.

Xu Qiu has completed the initial theoretical research.

It only needs to verify the feasibility of the blood vessel preparation plan recorded on the three manuscripts to make that epoch-making film.

Now that everything is ready, he can't just give up.

"Keep your money, I have a way."

Xu Qiu repeated.

After the others left, he made a phone call.

Yang Chenxi's voice soon came from the other side, "Comrade Xu, what do you want to talk to me about?"

In the background noise, there are many precision instruments beeping.

Xu Qiu said: "Professor Yang, do you have time to come to Linhai?"

"I may not be able to spare the time in recent years. Our team is now working on 6.5mm artificial blood vessels, which are estimated to be clinically applied within two years."

Xu Qiu nodded.

Sure enough, he is busy with this matter...

The team that has gone the furthest in the field of artificial blood vessels in China is actually Yang Chenxi's team.

His science and technology park has a scale of nearly 100 million yuan, and the industrial zone produces a considerable number of artificial blood vessels every year.

The core patent belongs to the orthopedic country Maikewei, and the materials have been localized "substitutes", which can be regarded as pseudo-domestic products.

Imported artificial blood vessels are about 40,000, while pseudo-domestic products only cost 10,000 yuan.

But the bad thing is that 17.3% of them need to pay patent fees.

That is to say, even if McCoy, who holds the patent, does nothing, he can still take nearly 20% of the profit from each artificial blood vessel!

This is why it is said that Daxia does not have real domestic artificial blood vessels.

Yang Chenxi's team is now trying to launch a 6.5mm artificial blood vessel that is less dependent on imports and more domestically produced. If it succeeds, the technology can be used in other calibers...

Then, Daxia will have the opportunity to completely turn medium and large artificial blood vessels above 8mm into truly domestically produced ones!

The significance is quite profound!

This is why, as soon as Yang Chenxi finished the famous knife competition, he immediately rushed back to Fuwai and plunged into the laboratory.

"Professor Yang, I remember you said that the 6.5mm artificial blood vessel has completed animal experiments. Now we just need to improve some details before we can try to enter the clinic, right?" Xu Qiu asked.

Yang Chenxi smiled proudly: "Yes, how about it, do you want to get a gold plate? If you want to do blood vessels, you can't avoid Fuwai, and you can't avoid me!"

Xu Qiu nodded: "That's right."

You can't avoid Fuwai and the various instruments and equipment you brought.

This changed the meaning of Yang Chenxi's words, and he was delighted: "You admit it too? Then come quickly, stay in my laboratory for a few years, make 6.5mm artificial blood vessels, and then completely eliminate the import of large and medium-sized blood vessels. We can be regarded as the founders of domestic artificial blood vessels!"

Xu Qiu said in a flat tone: "The domestic founder... is very attractive."

Yang Chenxi smiled and said: "Of course, whether it is our artificial blood vessels in Fuwai or other so-called domestic products, the core patents are actually in the hands of foreign companies such as McCoy and Terumo. For every one we produce, we have to pay a large amount of patent fees, usage fees, etc.

Get rid of imports, that is the real domestic!

My team has completed 90% of it, and we are waiting for you to join us and make the final move!"

Xu Qiu continued: "The final move is the domestic founder, but if you come to me and make the final move, you will be the founder of small-caliber blood vessels that break the 6mm restricted area for mankind."

Yang Chenxi, who had originally planned a lot of benefits and wanted to trick Xu Qiu to Fuwai, was stunned.

"Forbidden... restricted area? The originator?"

Yang Chenxi swallowed his saliva, thinking of Xu Qiu's proposal, and immediately laughed: "6mm is a bit too far, and McCoy and others have not found the direction.

Many foreign literatures speculate that 6mm artificial blood vessels have higher requirements for preparation technology and material properties, which may be impossible to achieve with contemporary technology."

Xu Qiu asked back: "If they can't do it, can't we?"

"This..."

"We are worse than them?"

"I don't mean that..."

Yang Chenxi's voice became much smaller, and he was also angry in his heart.

Why can't they do it?

Xu Qiu listened to the increasingly suppressed breathing on the phone, realized that the time had come, and said the last sentence: "Making 6.5mm blood vessels will always follow the foreign countries.

But coming to Linhai, making new small-caliber blood vessels with me can completely break the monopoly and start the reverse restriction of small blood vessels around the world!"

Yang Chenxi's emotions have been fully mobilized. Hearing this plain but meaningful sentence, he felt a surge of blood in his chest, "Yes, following behind will only make them eat shit!"

Xu Qiu: ...

"That's probably what I mean..."

After hanging up the phone, Xu Qiu struck while the iron was hot and took a photo of part of three manuscripts and sent it to Yang Chenxi.

This is his trump card.

It is also the key to his ability to break through the 6mm restricted area.

After sending the photos, Xu Qiu put down his phone and returned to the emergency department to prepare for outpatient visits.

No matter how big the market is, no matter how exaggerated the honor and reputation are, they are just external things.

Xu Qiu always has only one label: doctor.

No matter where he goes in the future, the first place is the patients with desperate eyes and vitality extinguished by illness.

...

When he went to the outpatient clinic again, the No. 7 clinic of the emergency department was directly exploded!

As a last resort, the security department coordinated a small team to come here to maintain discipline.

Other doctors were also called to Xu Qiu's place to help.

Four tables were set up in the No. 7 clinic, and the poor doctors He Hai, Zhou Hua and others helped to see patients.

There was no way...

They were in their own clinic, and there were no patients at all.

Coming here, even if they just sat next to Xu Qiu, in the eyes of the patients, their professional level suddenly increased a lot.

More useful than baldness!

There was also a psychopath who rushed into the clinic and took a breath, and then muttered:

"It's worthy of being Dr. Xu. The air here seems to have come out of a hydrogen generator. I feel like my cancer is almost cured."

He Hai:...

At first I just wanted to leave him an appendix, but now the appendix he cut off looks more like a doctor than me. How come!
