Daqin: Signing in at the beginning is ten times the combat power of Lu Bu

Chapter 389 The Invention of the Stethoscope

"The wave behind the river pushes the wave ahead, and the new generation is better than the old."

"Yes, the new editor-in-chief of Daqin Daily seems to have sharper words!"

Ying Yu looked at the headline on the front page of the latest issue of "Daqin Daily", and couldn't help showing a smile on his face.

Today's Daqin needs most is this kind of spirit of loyal performance, determination to forge ahead, and daring to do something.

Only in this way can Daqin truly achieve long-term and stable development and stand proudly on top of the world!

"This is all taught by you, husband."

Xiao Mei who was on the side smiled and said: "Now these graduates who claim to be the disciples of their husbands have become the new force of Daqin, and they have performed very well."

"Actually, I just gave them a few lessons. What really got them involved was the call and prospect of the great era."

"Young people are indeed very aggressive, but to keep this momentum going, there must be a correct guidance and a stage for them to play."

"And now the era of great development in Daqin is the best stage for young people to show their vitality, prove themselves, and achieve sublimation."

Ying Yu supported Xiao Mei to sit down beside her and said:

"Be careful, you are the key protection target now, if you accidentally hit it, I will feel so sorry for my husband."

"Husband, don't worry, she's not that delicate!"

Xiao Mei smiled sweetly and said: "This child is very well-behaved, so well-behaved that I often worry about it."

"Be well-behaved. If you really make a fuss, you, a mother, will suffer."

Ying Yu couldn't help laughing, put his ear next to Xiao Mei's pregnant belly and listened for a while:

"Don't worry, our little guy is very healthy."

"Really, I have been worried that the little guy will feel uncomfortable if he is too quiet."

Xiao Mei asked curiously: "Husband, can you teach me how to judge the development of a baby by listening?"

Yu Ji, Meng Ruyi and others nearby also focused their eyes.

Recently, they are helping Ying Yu sort out the materials on fetal health care for pregnant women. Among them, how to judge the development and growth of the fetus is a big problem.

"The fetus already has fetal heart sounds. By listening to the fetal heart sounds, the current development and health status of the fetus can be roughly judged."

Ying Yu explained with a smile.

"Is it what my husband said in the medical book?"

"Husband, can you tell me in detail, I also want to hear what the baby's fetal heart sounds look like."

Di Ya leaned over with a curious face, and put it on Xiao Mei's pregnant belly, listened carefully, and soon heard a vague voice.

However, although Di Ya was smart, she had no medical foundation, so it was difficult to distinguish the difference between the heartbeat sounds. Soon she pouted her mouth depressedly, which made Ying Yu laugh uncontrollably.

"This is actually very easy to distinguish, but it is indeed a bit difficult for ordinary people to do it, and it needs the assistance of a tool."

Ying Yu said with a smile.

"What tools do you need?"

Dea asked expectantly.

Following Ying Yu, there are always new gains, which is really interesting.

"Lu Zhi, go and get some materials according to the list above, and after finishing, you can hear the heartbeat clearly."

Ying Yu quickly took a pen and wrote down the required materials, and handed the list to Lu Zhi.

If you want to accurately listen to and distinguish the heartbeat, later generations will have a simple and practical artifact, which can be made in Daqin.

It just so happens that I have time now, so I will teach these girls a medical course.

As for why Lu Zhi was asked to come, it was because Lu Zhi had studied with Gong Shujie for a period of time and had the strongest hands-on ability.

Ying Yu is going to let Lu Zhi, Yu Ji and others make it by themselves, so the impression will be even deeper.

"His Royal Highness, what kind of drawings are you drawing!"

"It looks like two long pipes, hanging a small round box?"

"With just such a thing, can you distinguish different heartbeats?"

Yu Ji and the others couldn't help asking curiously.

Even Xiao Mei's eyes were attracted.

Being able to hear the baby's heartbeat at all times is definitely one of the most anticipated things for expectant mothers.

"Many things in this world, in fact, as long as you are willing to use your brain, there are simple solutions."

"Just like the purification of coarse salt that you saw last time, just simple cooking and filtering can turn the cheap coarse salt with many impurities into refined salt. The art of listening to the sound is actually the same."

Ying Yu explained with a smile.

Yu Ji and the others nodded their heads one after another, and the admiration on their faces grew stronger.

Although the principles of the inventions mentioned by Ying Yu are very simple, no one except Ying Yu can think of them.

The first to come up with a simple solution is a real genius.

"Husband, what invention are you going to toss about?"

At this moment, Wang Ying hugged Xiao Xin'er and walked over curiously.

Although Wang Ying was born in a military family, she also has some understanding of the craftsman's way.

"You will know when you make it."

Ying Yu took Xiao Xin'er from Wang Ying's arms with a smile, and kissed the little daughter's face lovingly.

Although the little guy can't speak yet, every time he sees his father, there will be a sweet smile on his little face, which makes Ying Yu dote very much.

It is indeed the most intimate little padded jacket.

On the other side, Yu Ji, Lu Zhi and the others had already fetched the materials, and started to make according to Ying Yu's drawings.

What they want to make is the Daqin version of the stethoscope.

Although the stethoscope has a wide range of uses, its structure is quite simple. It is essentially a sound amplifier. Through the accurately fitted auscultation head, the required sound is collected and amplified again, and it is conveyed to the ear through the airtight sound guide hall to complete the auscultation. Effect.

Among them, the earplugs and the sound guide tube only need to be bonded with rubber, and they were quickly made by Lu Zhi, Yu Ji and others.

In order to fit the ears better, Lu Zhi also added a layer of leather to the earplugs to cover the entire ears and make them more comfortable to wear.

The auscultation head uses a small and exquisite wooden box, the size of which is only one inch square. In order to increase the auscultation effect, a layer of skin membrane imitating the eardrum is added in the middle of the wooden box.

All sutured joints are tightly sealed with fish glue to ensure no sound or air leakage.

Soon, Daqin's first stethoscope was completed under the skillful hands of Lu Zhi, Yu Ji and others.

Looking at this simple little object in front of them, Yu Ji and the others couldn't help but feel a little bit more doubtful in anticipation.

As simple as two tubes and one box, can it really distinguish the heartbeat of pregnant women and fetuses, and judge their health?

It's too amazing, right?
