The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 153: Breakthrough in the Medical Field

Xie Yajun quickly asked all the medical staff who came to observe to cheer up.

Those who were called to participate in this observation were all key doctors of the hospital.

Everyone also knew the importance of this on-site learning. One by one, everyone opened their eyes wide and pricked up their ears.

The patient lying on the examination bed was also very cooperative and tried his best to lie down properly so that he could be examined more carefully.

Wang Haoran placed the color ultrasound probe on the patient's kidney.

Immediately, the display showed the inside of the kidney.

"The urinary retention is very serious!"

Wang Haoran said something.

Xie Yijun nodded and said, "That's true."

"In this case, if surgery is not performed promptly, it will be very dangerous to the kidneys."

The monitor shows the situation inside the kidney very clearly.

Even the blood vessels are clearly visible.

Wang Haoran continued to move the probe in his hand.

Soon, I saw a urinary stone about three or four centimeters in size blocking the urinary tract, leaving only a tiny space for a little urine to be discharged.

No wonder the patient feels so much pain.

"See? That urinary stone is almost completely blocking the urinary tract." Wang Haoran said.

The doctors all nodded.

Xie Yijun asked: "Comrade Haoran, can this stone be measured?"

Wang Haoran smiled and said, "Of course it can be measured."

He operated it, and an accurate estimate of the stone size appeared on the display.

This stone was as big as 3.9 centimeters.

What’s more, it was a posterior urethral stone!

This will cause quite a bit of trouble to deal with.

Xie Yijun said: "For a stone this big, I'm afraid surgery is the only option."

Wang Haoran was a little surprised: "Our hospital doesn't have an extracorporeal ultrasonic lithotripsy machine?"

Xie Yijun smiled bitterly: "That thing is not made in China. If it is imported, it is a bit expensive."

"Anyway, our hospital doesn't have one. I heard that Union Hospital has imported lithotripters?"

The patient lying on the bed said at this time: "The lithotripter at Union Hospital has broken down and is still under repair. I came here from there."

"Also, Union Hospital doesn't have an ultrasound machine as good as yours."

Xie Yijun spread his hands and said helplessly: "I'm sorry, we don't have a lithotripsy here. If you choose to have surgery, we will do it for you."

The patient on the examination bed was about to cry: "It's such a minor illness, and we have to have a major operation?"

"Is there no other way?"

Xie Yijun said: "There is really no other way."

"If your stones are relatively small, we can use some diuretics. If you drink more water and exercise more, maybe the stones will be expelled."

"But now, the stones are too big to pass out."

Wang Haoran, who had been silent the whole time, said: "I have read about the introduction of ultrasonic lithotripsy abroad. In fact, the principle is quite simple."

"Thank you, Dean. Why don't you help the patient urinate and relieve the pain first?"

"How about I think about building an ultrasonic lithotripsy machine?"

Xie Yajun was immediately delighted.

Wang Haoran developed the color B-ultrasound machine in just half a month.

The ultrasonic lithotripsy is actually much simpler than color ultrasound.

This genius must be able to develop it more quickly, right?

"Okay, okay! Then we will give the patient palliative treatment first, and wait for you to build the ultrasonic lithotripsy." Xie Yajun said with a smile.

Wang Haoran returned to his own laboratory at Pangu Corporation.

He wrote a purchase order and asked someone to buy the raw materials.

The raw materials were purchased quickly.

Wang Haoran started to get busy in the laboratory.

The principle used by this ultrasonic lithotripter is that high-energy ultrasound produces changes in pressure and temperature inside the stone, causing the stone to break and shatter.

When ultrasound waves are focused on the stone, the pressure on the stone quickly exceeds its tolerance, causing it to rupture.

At the same time, the temperature inside the stone will rise rapidly, producing a thermal effect and further accelerating the stone crushing process.

The structure of the ultrasonic lithotripsy is quite simple.

The ultrasonic transmitter is its most important component. Combined with a few other bits and pieces, an ultrasonic lithotripter is almost complete.

Because of the time pressure, Wang Haoran designed and developed a relatively simple ultrasonic lithotripter this time.

In just over a day, he made the ultrasonic lithotripter.

On the third day, Wang Haoran called Xie Yajun and told him that he had made a simple ultrasonic lithotripter.

Xie Yajun was very happy to hear this, and he immediately said that he would go over to watch.

Wang Haoran told Xie Yajun that the patient's condition was still quite critical and that lithotripsy was needed as soon as possible.

So, he just brought the crusher over himself.

Wang Haoran personally brought the ultrasonic lithotripter to the hospital.

After Xie Yijun saw Wang Haoran, he said to him: "Comrade Haoran, the patient is in great pain now. He is in unbearable pain every day."

Wang Haoran said: "Then hold on tight."

"Let's perform extracorporeal lithotripsy on the patient first."

“Hopefully it will work.”

"As long as we can break up that big stone, it will be easy to deal with."

Wang Haoran arranged the lithotripter in the color ultrasound room.

After more than a day, the first thing to do is to check the patient's color ultrasound results to see if the position of the stones has changed.

The patient was helped over.

Wang Haoran first performed another color ultrasound on the other party.

It was found that the large stone was stuck in the urethra and did not move at all.

It seems that the situation is even more serious now.

Wang Haoran immediately started extracorporeal lithotripsy.

He already knew where the stones were, so he could use ultrasound to impact them in a targeted manner.

This extracorporeal lithotripsy must be used with extreme caution and cannot be used casually.

Because the kidney is a very fragile organ. If the ultrasonic impact is too great, it will cause great harm to the kidney.

Wang Haoran adjusted the frequency and intensity of the ultrasound and began to perform extracorporeal lithotripsy.

This requires attacking the stones from different directions.

The extracorporeal lithotripsy took about several minutes.

After the procedure was completed, Wang Haoran immediately performed a color ultrasound examination.

As soon as he saw it, he started laughing.

Because that big stone has now been broken into six or seven pieces.

The size of each piece is much, much smaller.

The largest piece is only 7 mm left.

The gravel was carried out successfully.

The doctors watching nearby also saw this result.

Everyone was surprised.

Because this extracorporeal ultrasonic lithotripsy is so easy to use, right?

"Wow!"

There was a burst of warm applause in the room.

The stones in the patient's right kidney were broken into small pieces, creating gaps in the urethra, through which the accumulated fluid flowed.

He immediately felt relaxed all over.

"What's going on?" the patient asked.

Wang Haoran smiled and said, "Congratulations! The stone crushing went smoothly."

"The big stone has now turned into several small pieces."

"You should drink more water and stone-removing granules, and then exercise more. It is best to jump frequently to help the stones move downward."

The patient got off the examination bed and he hurried to the toilet.

In the toilet, he still felt it was very difficult to urinate.

It's like the faucet is blocked.

He squeezed out a little bit with force.

Suddenly, he felt as if something was squeezed out of his urethra.

"Ding!"

A small stone fell into the urinal.

He immediately found it much easier to urinate.

“Ding, ding, ding—”

In a very short period of time, several small stones fell into the urinal.

He felt the freedom and ease of urinating that he hadn't felt in a while.

It took me nearly a minute to pee.

Now, the elder brother feels no more pain or bloating, as if a huge stone has been removed from his body. He feels so light that he seems to be able to jump ten feet high with one leap.

When the eldest brother finished relieving himself, he squatted down to look at the urinal. There were six or seven small broken stones in it, which were almost orange-yellow in color.

He even wondered if he had urinated out a few grains of gold.

The eldest brother originally wanted to pick up all the small stones.

Later I felt it was dirty and ended up not picking it up.

He turned around and came out of the bathroom, and saw several doctors standing outside.

Xie Yijun stood at the front.

Seeing the patient coming out, Xie Yijun smiled and said, "I just heard you shouting in there."

"Is the stone coming out?" The patient nodded quickly, his face smiling like an old chrysanthemum.

"Yes, yes! The stones are out, all of them. Now I can pee smoothly. Haha!"

"Now I feel so relaxed! This feeling is so good."

Xie Yijun was in a better mood. He pulled the patient's arm and said, "Hurry up and do another color Doppler ultrasound to see if it has really been completely excreted from the body."

Wang Haoran also came over at this time.

As soon as he saw the relaxed look on the patient's face, he knew that the stones should have been completely expelled.

He smiled and said, "Yes, come over and take another B-ultrasound. It should have been completely expelled."

The patient lies back on the examination table.

This time it was not Wang Haoran who performed the B-ultrasound on him.

Instead, a young doctor took over.

The young doctor followed the steps taught by Wang Haoran.

After a while, the results came out: the stone in the patient's right kidney where it was originally blocked had completely disappeared!

The original large amount of fluid accumulation has also disappeared.

In fact, the large amount of accumulated fluid is urine.

Xie Yijun was very excited and moved. He held Wang Haoran's hand tightly and said, "Comrade Haoran! Thank you! The two medical devices you developed are what we need most!"

"You have filled a gap in the country! Haha!"

Wang Haoran smiled and said, "Now, what I have to do is to mass-produce these two medical devices so that hospitals across the country can use them!"

The patient hasn't left yet.

He said to Wang Haoran gratefully: "Comrade, you saved my life this time!"

"If the stone can't be removed, I think I will die on it."

"I want to give you a banner!"

"Excuse me, what is your name?"

Wang Haoran is now wearing a white coat and a mask.

So, the patient didn't recognize him at all.

Wang Haoran smiled and said, "I'm not a doctor. If you want to give a banner, just give it to your attending physician!"

The patient shook his head: "No, that won't work. You saved me! How can I give this banner to someone else?"

"You are not a doctor, so how can you treat me in the hospital?"

Wang Haoran had no choice but to take off his mask and said, "I developed these two medical devices. I came here just to test them and see if they are useful."

When the patient saw Wang Haoran's face, his eyes widened instantly.

Then, he shouted in surprise: "Ah?!"

"You are Comrade Wang Haoran!"

Wang Haoran nodded with a smile and said, "It's me."

The patient said, "Then I know where to send the banner. I will go to Beijing Institute of Technology to deliver it to you."

Wang Haoran was a little helpless. He said, "Why bother? Haha!"

"Wouldn't it be nice to save some money?"

The patient's elder brother said: "I have to thank you for saving my life anyway."

Wang Haoran had no choice but to let the other party go.

Next, Wang Haoran began to train the doctors in the hospital on how to operate the ultrasonic lithotripsy and color ultrasound machines.

During the training process, it is natural to also experiment on patients.

That day, the third person who came in for color ultrasound was a young woman with a big pregnant belly.

The pregnant woman was accompanied by a middle-aged woman.

After coming in, the pregnant woman said to Wang Haoran before she even lay down on the examination bed: "Comrade, can your machine tell whether it's a boy or a girl?"

Wang Haoran immediately became a little alert.

Because now family planning has become obviously much stricter.

What does it mean when this woman asks to know the gender?
Could it be that she only gave birth to girls before, so she is desperately wanting a boy now?

However, I am already so advanced in my pregnancy. If I don’t want to have the baby, wouldn’t it be very dangerous?
"Comrade, I'm afraid I can't tell you the baby's gender." Wang Haoran said, "Because the national regulations prohibit the disclosure of the baby's gender."

In fact, there is no B-ultrasound yet, so there is no regulation prohibiting the disclosure of the baby's gender.

The young pregnant woman was very disappointed when she heard this.

"Oh, okay."

She got on the examination bed.

A female doctor was assigned to examine the pregnant woman.

Wang Haoran was giving instructions on the side.

This pregnant woman has been pregnant for at least 7 months.

The fetus is already quite large and very active.

The fetus' development is normal.

It was obvious at first glance that the fetus was a boy.

After the examination, photos of the fetal examination were printed out.

The young pregnant woman was also helped down from the examination bed.
She glanced at Wang Haoran, seeming to want to say something but stopping herself.

At this time, Wang Haoran saw that a one-inch photo fell out of the pregnant woman's pocket when she got out of bed.

It was a photo of a young soldier.

The photo is in black and white.

Wang Haoran bent down and picked up the photo.

"This is the photo you dropped just now." Wang Haoran took a look at the person in the photo and confirmed that it was a soldier. He said to the pregnant woman.

When the young pregnant woman took the photo, her eyes suddenly turned red.

"Thank you!" she said.

Wang Haoran's heart skipped a beat and he had an ominous feeling.

"You're welcome. That's your husband in the photo, right?"

The young pregnant woman nodded and said, "Yes, he is my man."

"However, he has died on the battlefield in the south."

"Woo-"

"The baby in my belly is his only offspring."

"So, I just want to know if I'm pregnant with a boy."

The young pregnant woman started crying.

Wang Haoran was a little flustered.

"Sister, I'm telling you, you're pregnant with a boy."

"The fetus is very healthy and there is no problem at all."

"Also, my elder brother sacrificed his life for the country. He is a good man of our Chinese nation!"

"I salute you."

The young pregnant woman wiped her tears, smiled and said, "Thank you, comrade!"

"My man is pregnant!"

"This is such a great thing!"

Wang Haoran sighed inwardly and said, "Sister, give birth to the child and raise him well. The motherland and the people will thank you for your efforts!"

……

Wang Haoran reported the results of the color ultrasound machine and the extracorporeal ultrasonic lithotripsy to the Ministry of Health of Longguo.

At the same time, he also asked people to apply for various patents for these two achievements.

The person in charge of Longguo’s Ministry of Health is Tang Weidong.

Tang Weidong was overjoyed when he saw these two achievements.

Because these two achievements are indeed blank in China.

In domestic hospitals, many medical devices currently need to be imported from abroad.

The import price is too expensive.

Therefore, nowadays, except for the top pediatric hospitals in the country, there are almost no decent examinations.

Color Doppler ultrasound examination is a widely used medical device that can detect many diseases.

This thing is very important to the hospital.

Tang Weidong immediately reported the matter to the higher-ups.

When the leader saw that Wang Haoran had made a big name for himself in the medical field, he was surprised.

The designer was very happy, so he called Wang Haoran personally.

He said, "Comrade Haoran! I haven't seen you for a few days, and you've come up with another great achievement!"

"The color Doppler ultrasound machine you developed is extremely important! It can greatly improve our medical examination capabilities!"

"Come here, let's talk some more."

Wang Haoran went to see the leader.

When the leader saw Wang Haoran, he shook hands with him warmly and said, "Haoran! I still have to thank you! Someone has brought the color ultrasound machine you developed to me for inspection."

"I even got checked out by it myself."

"I heard from Tang Weidong that even Yosa doesn't have this kind of high-definition color B-ultrasound machine!"

"It's very advanced! It's the most advanced ultrasound machine in the world!"

"Yeah! That stone crusher is pretty good too!"

"For patients with stones, it is really a blessing!"

"I have been thinking about whether we should set up a large state-owned enterprise specializing in medical equipment to conduct research and production in this area."

Wang Haoran smiled and said, "Leader, I think we need to set up a national medical device company! We need to do a good job in this area!"

"If it is done well, it can not only meet domestic medical needs, but also earn foreign exchange through exports. It is a win-win situation!"

"Well! I suggest that this company be directly managed by the Ministry of Health! I believe that we can make up for our shortcomings in medical devices in five years at most."

The leader nodded with a smile and said, "I feel a little regretful now!"

“This regret is——”
