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

Chapter 152 Developing Color Doppler Ultrasound for My Wife [Full Order]

After Wang Haoran sent Yuan Longfei away, he returned to the laboratory and finished the unfinished work.

He successfully made ten pregnancy test strips.

After finishing the work, it was already around 3 o'clock in the afternoon and Wang Haoran returned home excitedly.

At the moment, only Xiao Lijuan was at home, busy packing up the swaddling clothes, blanket, mattress, small clothes, etc. that Wang Xinghai used when he was just born.

Seeing Wang Haoran opening the door and coming in, Xiao Lijuan smiled and said, "Are you back?"

As she spoke, she came over to get cotton slippers for Wang Haoran.

Wang Haoran quickly stopped her and said, "Lijuan, don't take care of me like this anymore, and don't tire yourself out. In the next three months, you will be the key protected person in our family."

Xiao Lijuan used her hands to tidy up her hair and said, "I don't know if she is pregnant again."

"Haoran, please don't be so nervous, okay?"

Wang Haoran smiled and took out the pregnancy test paper he had just made from the green canvas bag he was carrying, and said, "Is it true that I am pregnant? Let's test it."

Xiao Lijuan looked at the long test paper in Wang Haoran's hand curiously: "What is this?"

Wang Haoran said: "A test strip specifically used to test whether there is pregnancy..."

Wang Haoran explained the principle to Xiao Lijuan.

Xiao Lijuan took it, looked at it and said, "This is hard to make, right?"

Wang Haoran said: "Yes, I was busy in the laboratory for several hours."

"Let's test it tomorrow morning and see what the situation is."

Xiao Lijuan asked: "Why do we have to wait until tomorrow morning?"

Wang Haoran said: "Because the progesterone content in urine is the highest in the morning, it is also the easiest to detect whether you are pregnant."

Xiao Lijuan bit her lip lightly and said, "Then I'll try it now, it should work, right?"

Wang Haoran counted on his fingers and said, "It should have been about 22 days since your last ovulation."

"I remember we calculated the date to have a child."

"So, if you are really pregnant, you should have been pregnant for at least 20 days now."

"So, you are now three weeks pregnant."

"Yeah! I think that even though it's still early pregnancy, it should be detectable."

"Then let's try it now."

Xiao Lijuan excitedly took the test paper and went to the toilet.

The test was conducted using an open cup made by Wang Haoran from a wine bottle.

Wang Haoran originally wanted to go over and take a look.

However, he was also worried that no one was taking care of his son who was sleeping in the bed in the bedroom.

So he just stood at the door watching the child.

After only six or seven minutes, Xiao Lijuan's voice came from the toilet: "Haoran, come quickly!"

Wang Haoran hurriedly strode over.

Xiao Lijuan held the test strip in her hand.

Two red bars appeared on it.

Of course, the one below is slightly shallower.

“It’s got it!”

"Very clear pregnancy positive."

Wang Haoran said with a little joy.

"Oh!" Xiao Lijuan pouted her lips, looking a little mixed with joy and sorrow.

Wang Haoran stretched out his hand and held her slender waist: "What's wrong?"

"You seem a little unhappy."

Xiao Lijuan sighed softly and said, "So, will I not be able to hold you in my arms to sleep for another three months?"

So this is what she was worried about.

Wang Haoran smiled and said, "Well, tell mom. From now on, I will accompany you at night."

"Don't worry, I can bear it."

Xiao Lijuan blushed and said, "Thank you for your hard work."

Wang Haoran hugged her and kissed her gently, then said with a smile: "It's not hard! For the sake of the next generation, what does it matter if we suffer a little bit."

The two were talking in the small bathroom, and their eyes were gradually getting hot and their hearts were beating fast. Suddenly, Wang Haoran heard a slight noise outside.

He quickly opened the door.

He saw his one-year-old son Wang Xinghai staring at him and Xiao Lijuan hugging each other with his big dark eyes wide open.

Wang Xinghai was obviously a little surprised.

Wang Haoran wondered if his son would cry in the next second.

Xiao Lijuan wanted to go out and pick up her son to comfort him, but at this moment, Wang Xinghai actually raised his two little hands to cover his eyes, and then giggled.

The child also said: "I can't see you."

"Go on, you guys."

"Giggle..."

The child said this and turned to walk towards the bedroom with a unsteady gait.

After taking two steps and nearly falling, he actually pushed himself up with his hands, stood up again, and ran towards the bedroom.

He is like a little duck, his steps are so cute and funny.

Wang Haoran was a little surprised.

This child is only one year and four months old! He seems to have a vague understanding of the things that happen between adults.

"Did you forget to drink Meng Po soup?"

Xiao Lijuan had already put the test paper in Wang Haoran's hand, and she chased out.

Soon, the sound of children's laughter could be heard from the bedroom.

Wang Haoran took a look at the two lines on the test paper and thought, why not go to the hospital tomorrow.

See if your test paper really works.

The next day, Wang Haoran took Xiao Lijuan to a nearby hospital.

When he went there, he specially brought with him the unused pregnancy test paper that he had developed himself.

Although it is the Spring Festival holiday, there are actually quite a few people in the hospital.

But there are only a few doctors on duty in the hospital.

Wang Haoran did not go to wait in line.

Because, I don’t know how long I have to wait.

Knowing that Wang Haoran was going to take his wife to check whether she was pregnant today, the relevant department arranged a female gynecologist who was supposed to be on vacation.

There are very few examination equipments in Longguo Hospital now.

To check whether you are pregnant, a blood test is the safest option.

Because I went through the green channel, the test results came out not long after.

The doctor who treated Xiao Lijuan was Wu Xiuzhen.

Dr. Wu is probably in his 40s.

Before the blood test results came out, she did some checks based on her experience, and then she said to Wang Haoran with great certainty: "Comrade Haoran, it has been confirmed that your wife is pregnant."

When the test results came out, she just took a look and said, "The test results also confirmed that I am indeed pregnant. It is estimated that I am about 3 weeks pregnant."

"Next, eat well, sleep well, exercise moderately, and don't overwork yourself, and you'll be fine."

"Also, it's best not to have sex, because it can easily cause miscarriage."

Wang Haoran hurriedly thanked him.

He took out the pregnancy test paper he developed and talked to Wu Xiuzhen about it.

Wu Xiuzhen looked at the test strip again and again with great interest and said, "If the test is really accurate, it can be promoted in China."

"Comrade Haoran, you should conduct a clinical test on this result to see how it works."

Wang Haoran smiled and said, "I have sorted out some research and development processes here. If the clinical test results are good, I can also design a production line specifically for this purpose."

"As long as it is beneficial to the people, we should do more!"

As Wang Haoran spoke, he handed Wu Xiuzhen dozens of sheets of paper containing the production process of pregnancy test strips that he had compiled that day.

These dozens of sheets of paper are quite comprehensive, and even have a schematic diagram of the entire production process. Important production equipment has process design drawings.

This hospital is a key municipal hospital. The medical systems should be connected now, right?
The main reason is that Wang Haoran doesn’t want to worry about this matter too much.

Wu Xiuzhen flipped through the things Wang Haoran handed her and she felt a little flustered.

Well, you're giving me all the production techniques and stuff?
"Oh, thank you Comrade Haoran. Let me call our dean and ask him to come over and talk to you."

Soon, the hospital's director Xie Yajun hurried over.

He looked at the information on making pregnancy test strips that Wang Haoran had sorted out and said happily, "Comrade Haoran! This is a good thing!"

"It will be convenient for people to test whether they are pregnant at home, so that the hospital can save manpower! Oh! The pressure on hospitals is really great now!"

Wang Haoran smiled and said, "I see your hospital basically doesn't have any important examination equipment."

This hospital is a combination of traditional Chinese and Western medicine, but it does not have many Western medicine examination equipment.

Xie Yijun said: "Don't mention it. The domestic production rate of Western medical examination equipment in our country is very low. If we import it from abroad, it will be too expensive."

"Ah! For example, the best way to check the fetus is actually B-ultrasound."

"But we don't even have a B-ultrasound machine. How can we have good eugenics?"

Wang Haoran's mind moved. The B-ultrasound machine is indeed a very important medical examination equipment that can detect many diseases.

Moreover, this inspection method does not cause any harm to the human body.

For my wife's safety, it seems that I have to find a way to develop a batch of medical devices.

For example, B-ultrasound machine, electrocardiogram, fetal heart rate monitor, hysteroscope, etc.

Another example is the development of electric cutting knives and cold cutting knives. The backwardness of medical equipment will become a big problem in the future.

Wang Haoran said to Xie Yijun: "President Xie, I will think of a way to develop a domestically produced B-ultrasound machine or something."

When Xie Yajun heard this, he was overjoyed.

Since Wang Haoran said he would help the hospital find a solution, he will definitely be able to find one.

Because Wang Haoran is a rare genius in Long Country who spans multiple scientific research fields.

Xie Yijun hurriedly thanked him: "Thank you, Comrade Haoran!"

"Then it's up to you!"

"Our medical field is in a very difficult situation right now!"

“Your strong support is so needed!”

So, while Wang Haoran accompanied Xiao Lijuan for a check-up, he added another task to himself.

Wang Haoran felt that his most urgent task was to develop the color ultrasound machine first.

If you want to do it, then do something more advanced and clear.

There is no point in developing a black and white B-ultrasound machine.

……

After confirming that Xiao Lijuan was pregnant, Wang Haoran naturally had to spend more time with his wife in the next few days and give her some emotional comfort.

In the blink of an eye, it is the fifth day of the New Year.

That morning, Wang Haoran naturally went to Pangu Computer Technology Company.

After the New Year, we have to hold a meeting immediately to motivate the employees.

Wang Haoran held a meeting for middle-level managers in the morning.

At the meeting, a goal was set: by mid-March this year, the company would start mass production! It would take one month to increase the output of microcomputers to 3 units per month! By the middle of this year, the monthly output of computers would reach 2 units.

The tasks naturally need to be broken down layer by layer.

Where there are tasks, there will be rewards and punishments.

The reward is really generous.

The punishment is also severe.

Wang Haoran announced at the meeting: The company's management system is a red line that no one can cross!

After the meeting, Wang Haoran just returned to the office and saw Guo Qing, the main person in charge of Pingu County, and the director of Pingu Machinery Factory waiting for him.

When Guo Qing saw Wang Haoran, he immediately smiled and greeted him: "Comrade Haoran, Happy New Year!"

"I originally thought that the fifth day of the New Year was a day off, and it just happened to be coming to an end, so I came to visit you. I didn't expect that when I arrived at your house, your wife told me that you had already started working."

"We have no choice but to come to visit you at work."

Guo Qing seemed a little frightened.

More than two years ago, Wang Haoran was just an educated youth under his jurisdiction.

More than two years later, Wang Haoran had become the head of Pangu, a large state-owned enterprise.

The level of Pangu Company is quite high, equivalent to that of a vice-minister.

Taller than Guo Qing.

Moreover, this young man also reported to the emperor...

Wang Haoran shook hands with Guo Qing and greeted him and his family.

The three of them sat down and reminisced about the past.

Reminiscing about the past is mainly to bring people closer together.

After talking for a while, the three of them became more and more enthusiastic.

Wang Haoran knew why Guo Qing and Yuan Longfei came.

He didn't beat around the bush and directly told Guo Qing and Yuan Longfei, "Comrade Guo Qing, have you confirmed it?"

“This first domestically produced refrigerator and freezer production line is a truly great project!”

"If you want to receive it, you have to hurry up and invest in construction."

Guo Qing immediately patted his chest and said, "Comrade Haoran, we have to decide on this project!"

"Thank you for thinking of us like this!"

Wang Haoran said: "Then I will give you the drawings. In addition, our scientific research team will give you some guidance and help when the production line is built and installed."

Guo Qing said gratefully: "This is equivalent to teaching the people of Pingu County how to get rich step by step!"

"Thank you so much."

Wang Haoran smiled and waved his hand: “You’re welcome!”

"It's all for the purpose of enabling our country to develop faster and better!"

Wang Haoran made a phone call and called Guo Mingliang and several other key scientific research personnel to Pangu Company.

He asked Guo Mingliang and others to connect with Guo Qing and Yuan Longfei.

This matter was arranged.

……

Wang Haoran then began to use his spare time to develop a color B-ultrasound machine.

The design and manufacturing process drawings of the world's best color ultrasound machines are all in Wang Haoran's mind.

However, he certainly couldn't bring out the best all at once.

Wang Haoran set up a test workshop for himself in Pangu Company’s office building and made some experimental equipment by himself.

One of the most important parts of this color ultrasound machine is the color ultrasound probe.

It is a key component for inspection.

Its application principle is mainly to generate ultrasonic signals through piezoelectric effect, which plays the role of generating, collecting, receiving and transmitting ultrasonic signals.

The probe is generally composed of a lens, a matching layer, a crystal, a backing material, etc. to form a sound head, which is then packaged through a detection housing and a tail sleeve to form a detection unit.

In addition to the probe, there are also ultrasonic transmitting/receiving circuits as well as signal processing and image display light parts.

When studying color ultrasound, Wang Haoran did not ask for any other help.

Because he felt that making this device was a gift to his unborn child.

You must do it yourself to show your greatest sincerity.

Wang Haoran developed color ultrasound purely by making use of his spare time.

But even so, just half a month later, he built a color ultrasound machine by himself.

The display device used is a computer monitor.

The processor used is the ready-made Pangu 4.

The printing device used is Pangu laser printer.

In short, it is now quite easy to build this color ultrasound machine.

After the color ultrasound was developed, Wang Haoran originally wanted to try it on his wife first.

However, he thought again that there was no point in doing color ultrasound of the fetus before 3 months.

He called Xie Yajun, the director of the designated hospital where his wife had her pregnancy check-up.

When Xie Yajun heard that Wang Haoran had developed a color B-ultrasound machine.

He was very shocked, and then felt happy.

Xie Yajun immediately rushed to Pangu Company in person.

He saw the freshly assembled color ultrasound equipment in Wang Haoran's laboratory.

"Wow! This is too advanced, isn't it? Thank you, Comrade Haoran!" Xie Yajun said with a smile when he saw the device turned on and a color window appeared on the display.

Wang Haoran smiled and said, "Dean Xie, let's try it now to see if this device works well?"

Xie Yijun scratched his head and said, "How about moving to our hospital?"

"We have a lot of patients in our hospital. We can take photos of them and help the patients at the same time."

Wang Haoran nodded and said, "That's fine!"

"Let's test it in your hospital for a few days to see if there are any deficiencies!"

"If everything goes well, we will apply for a patent and plan to build a workshop for production."

A complete set of color ultrasound equipment was sent to Xie Yajun's hospital.

This equipment is placed on the laboratory floor.

There are quite a few empty rooms here. Due to the lack of medical equipment, the items that should be examined with instruments can only be diagnosed using the old method of observation, auscultation, questioning and palpation.

After the color ultrasound machine was arranged, Xie Yajun immediately asked someone to call a few patients over.

One of the male patients was suffering from severe back pain and could not stand up, with beads of sweat rolling down his forehead.

Wang Haoran knew at a glance that this person obviously had kidney problems.

I asked him when the pain started, and he said it was sudden and severe pain two days ago.

This is obviously caused by kidney stones.

The man was barely helped by his family to lie down on a bed for examination.

Because the color ultrasound machine was a new device and no doctor in the hospital knew how to use it, Wang Haoran had to do it himself this time.

Around him, there were a dozen medical staff who had come to watch.

Of course Wang Haoran must fulfill the purpose of teaching.

He began to introduce to the medical staff around him how to use the color ultrasound machine.

While introducing, he asked the man to lie on his left side.

Because this man had pain in his right waist.

This is very obvious, there is something wrong with the right kidney.

Wang Haoran waited for the man to lie down, and then he applied a layer of coupling agent on the man.

He turned to Xie Yijun and other medical staff at the hospital and said, "Now, I'm going to start the color Doppler ultrasound. You all watch."
