"Yes, you are all very ingenious and worthy of praise."

Ying Yu carefully checked the stethoscope in his hand and smiled slightly.

"Your Highness, now that the tool has been made, how can we distinguish the heartbeat sound?"

Yu Ji asked curiously.

During this period of time following Ying Yu, Yu Ji saw many novel things, which were much more interesting than the stagnant Yujia Village.

Of course, the most important thing is the human factor.

"This thing is actually very simple to use. I will show you how to use it. I believe you will learn it."

After finishing his words, Ying Yu looked at Xiao Mei and let himself use the first stethoscope in Da Qin to conduct a physical examination on Xiao Mei.

By the way, you can also listen to the heartbeat of your baby who is still pregnant.

"Husband, what are you going to do?"

Watching Ying Yu hang up the earplugs of the stethoscope and hold the round small box against her belly, a trace of doubt flashed across Xiao Mei's face.

"Didn't you say you wanted to listen to the little guy's heartbeat before? Now is the time to test the effect of this tool."

"If everything goes well, Xiao Mei, you will be able to hear the little one's fetal heartbeat soon."

Ying Yu smiled slightly.

"Really?"

A look of surprise flashed across Xiao Mei's face.

Ever since she was pregnant with the little guy, Xiao Mei has been looking forward to the birth of the little guy. She is worried when the little guy is noisy and worried when she is quiet. In her free time, she will whisper to the little guy and do what is said in the book.

of prenatal education.

Now being able to communicate with the little one, even just hearing the fetal heartbeat, is enough for her to look forward to.

Not only Xiao Mei, but also Wang Ying, De Ya, Lu Pheasant and others also gathered around curiously, wanting to witness the magic of this gadget.

However, Ying Yu remained unhurried and held the auscultation head in his hand, which immediately made Yu Ji feel uneasy.

"Your Highness, did we fail to do a good job and there is something wrong with the speaker?"

Yu Ji asked softly.

"It's okay. This stethoscope is very well made."

"The reason why we hold the stethoscope in our hands first is because the temperature of the stethoscope head is relatively low. We should first warm it in our hands until it is close to the body temperature, and then put it on it, so that the pregnant woman will not get cold, otherwise it may irritate the baby.

The sound you hear is not accurate."

Ying Yu explained with a smile: "You can record this. When medical staff use stethoscopes in the future, they must not ignore this."

In his previous life, Ying Yu had experienced the feeling of a cold stethoscope suddenly being pressed against him, and it was definitely stimulating enough.

This would be fine for normal people, but it may not be possible for pregnant women and infants who are already weak.

"Um!"

Yu Ji nodded quickly and carefully recorded Ying Yu's suggestions.

During this period of time, they all learned a lot from Ying Yu.

There is no small matter in medical care, and any negligence may lead to bad things happening.

Especially for pregnant women and infants, care must be taken with care.

At this time, Ying Yu finally started Da Qin's first auscultation test.

Although it was a bit crude, the effect was very good. Ying Yu quickly heard two different heartbeats, one big and one small, and he quickly distinguished them.

Xiao Mei and her little one were indeed in good health, which immediately made Ying Yu feel at ease and put a smile on his face.

"How is it, husband, did you hear the little one's voice?"

Xiao Mei said eagerly.

Although I was nervous and looking forward to it, I was afraid of surprising the little guy, so I didn't dare to speak too loudly.

"Don't worry, the little guy is very good. You can also listen to it and try it yourself."

Ying Yu smiled and took off the earplugs and gently hung them on Xiao Mei's ears.

"Hey, why are there two voices? Could they be twins?"

A look of surprise flashed across Xiao Mei's face.

"Silly girl, one of them is your own."

Ying Yu couldn't help but laugh.

No wonder there is a saying in later generations that one pregnancy makes one stupid for three years. Even someone as smart as Xiao Mei started to look a little stupid at this time.

In fact, caring can lead to chaos. As a mother, you must take good care of the baby you have worked so hard to give birth to for ten months, for fear of being a little neglectful.

"Well, I understand!"

"I heard it. This should be the little guy's fetal heartbeat. It's very lively. It's really good!"

Xiao Mei listened carefully to the little guy's heartbeat, her face full of surprise.

Nothing makes a mother happier than having her child healthy.

"Of course, with mother taking care of you like this, the little guy will definitely grow up strong."

"If mother is in a good mood, the little one can also feel it and become more lively and happy."

Ying Yu said with a smile.

"Husband, can you give me a try?"

A look of anticipation flashed across Deya's face.

Yu Ji and others also looked over, but they did not dare to speak.

After all, Xiao Mei is the crown prince's concubine, and she is pregnant with a prince or princess from the Qin Dynasty. Without Ying Yu's permission, they would not dare to act rashly.

"Yes, but be careful not to surprise Xiao Mei and the little guy."

Ying Yu smiled and said: "If you really want to try it, you can just listen to yourself later, or auscultate each other!"

"Um!"

Deya and others nodded repeatedly, lined up with great anticipation and began to listen.

"It's amazing. I can really hear two heartbeats, and it's so clear. It's incredible."

"Yes, the little guy's heart is beating very energetically, he must be very healthy!"

"With this artifact, we can also perform auscultation."

"I didn't expect that this little stethoscope could be of such great use. Your Highness the Prince's new invention is simply amazing."

"The doctors of Great Qin will be able to relax a lot in the future."

After Yu Ji and others tried the effect of the stethoscope, their faces were full of surprise.

Having studied medical skills with Ying Yu for a long time, they all now have a pretty good medical foundation and naturally understand what the stethoscope means to the doctors of Da Qin.

The traditional observation, hearing and asking can now be more detailed and precise.

And this means that the diagnosis accuracy of medical doctors will be higher and the efficiency will be improved.

In other words, more Daqin patients will benefit from this small stethoscope.

Yu Ji and others looked at Ying Yu with admiration in their eyes.

As expected of His Royal Highness, a random invention is a magical weapon that is beneficial to the country and the people.
