Tai Chi Palace.

Menxia Province.

In the morning, the rising sun of the Tang Dynasty was trying to climb up.

When the sound of reading in the Hongwen Pavilion sounded, the figure of His Royal Highness the Crown Prince also swept through the corridor and aisle of the Hongwen Pavilion.

At this time, someone deserted and quietly took a look, which was immediately caught by the bachelor who taught Jingyi, and pointed to the direction in which His Royal Highness the Crown Prince disappeared, and criticized them: "Look at it, even His Royal Highness the Crown Prince is more studious than you." ”

Alas, this group of royal relatives and heirs of the clan also thought it was really strange.

Is His Royal Highness the Crown Prince really so studious?

In recent days, it seems that the entire palace knows that His Royal Highness the Crown Prince is diligent and studious.

Wait until class is finally over.

They hurriedly asked Yao Silian, who was looking for books for the prince, what books His Royal Highness the crown prince was looking for.

Yao Silian also replied to them very generously, they are all books from ancient times that record the great achievements and good morals of the Three Emperors and Five Emperors.

His Royal Highness the Crown Prince wants to learn from the Three Emperors and the Five Emperors.

Many people were immediately ashamed.

In fact, even Yao Silian was a little surprised, because His Royal Highness the Crown Prince was only nine years old.

Who is this Li Chong, who is sacred, and he is the Three Emperors and Five Emperors.

Since he can teach His Royal Highness the Crown Prince, it means that the other party must be very familiar.

If you have the opportunity, you would like to see what the other person is capable of.

……

In the temple.

Yan Lide also asked His Royal Highness the Crown Prince why he was not here today?

Li Chong told him to go into the palace to find books.

"I thought of the check valve that you wanted?"

Yan Lide said, "No." ”

"Forehead ......"

"But I don't know, can I just tie it with a rope? If you want to deflate, loosen the rope. ”

The other party took out the airbag and showed it to him.

“……”

Li Zhong finished listening to Yan Lide's words. To be honest, I was really shocked by his words in an instant.

it!

it!

Can it still be like this!?

Really!

It's that he thinks it's complicated.

This is probably the so-called, knowledge blind spot.

Li Chong originally wanted to make a very convenient check valve for later generations.

Outcome......

What Yan Lide brought him was a primitive method that was just as troublesome.

"Then this blood pressure monitor is complete."

Li Chongdang even took out all the tools and used Yan Lide to do the experiment.

Don't say it's really good, but it may take at least two people to do it.

Fortunately.

There were guards outside, and Li Chong then went to call a guard in.

And then......

While cheering up, he watched the mercury soar, and after that, Li Zhong listened carefully to the sound coming from the stethoscope. Soon, with his clever brain, he seemed to have completely figured out how to operate.

When the air is inflated, you will suddenly not hear the sound of the pulse, and then, when the gas is almost released, you will hear the pulse again, and if you continue to deflate, you will suddenly find that the pulse is gone.

The first pulse heard is the systolic blood pressure, which is named systolic because it is the pressure generated by the human heart beating in the arteries when it contracts.

This pressure is naturally a large number.

In the same way, the other one is diastolic blood pressure.

Yan Lide waited quietly for Li Zhong to measure.

Li Chong tried a few more times.

Finally, I was sure that I should not be wrong in my test.

And......

He recalled the long-dusted physical examination list in his mind, as if the general slash was one hundred and twenty at the top and eighty or ninety at the bottom.

Of course, this self-made blood pressure monitor, the scale on it was reversed by him according to the density, volume, and mechanical formulas, and even the millimeters, which he drew by visual inspection, otherwise, did he have to use scientific means to determine how long a meter is before getting it? It's certainly not possible!

However, Li Zhong felt that as long as the error was within a certain range, this result was acceptable.

At one point, he even calculated what the range of this error was.

Now the measured results are exactly within the range of one hundred and twenty, and eighty or ninety, that is to say, Yan Lide's current physical condition should still be very good.

Next......

It is to find as many people as possible to test, and at the same time, to find some that can be seen at a glance that they must have high blood pressure.

For example......

Emperor Taishang, Li Yuan.

Li Yuanna must have high blood pressure!

It's hard to say, though.

What if he only had high blood pressure in his old age.

This day gave birth to a child, how many younger brothers and sisters did Li Er give birth to.

Therefore, Li Yuan is a middle comparison item for the time being.

If you want to find it, look for those that are already obvious.

For this, you can turn to Sun Simiao, after all, among Sun Simiao's patients, there should always be one or two.

Thinking about it, Li Chong couldn't wait to find Sun Simiao with a blood pressure monitor.

Fortunately, Sun Simiao didn't go out that day.

As soon as he heard that Li Chong had made it, and now he needed an experimental subject, he immediately introduced one to Li Chong.

Then the group drove there.

After arriving, I tested it, and sure enough, it was definitely high blood pressure.

That's up to one hundred and sixteen.

According to the patient's own account, he also felt a little dizzy in his head recently, and he was a little sluggish.

The point is that the other party also drank alcohol two days ago.

You see, this is the result of not listening to the doctor.

Because high blood pressure generally does not make people feel good, therefore, many patients feel that it does not matter, in fact, Chinese medicine should have a way to lower blood pressure, but even if it is lowered, it is useless, because the patient does not know how serious he is. Therefore, even if the blood pressure is lowered for a period of time, and then, because of reasons such as drinking, or not being in a good mood, the high blood pressure will recur again, and the doctor cannot follow it from time to time, and has been paying attention to the patient's condition, so it ......

Often, many people miss the best time for treatment. By the time it is discovered, it may have caused irreversible results. It's like this, I feel a little dizzy, so I think it's just a small problem, but what if I suddenly have a stroke?

At this point, it's too late to go to the doctor.

"Doctor Sun, what's the matter, my father's illness is very serious?"

Seeing Li Chong and Sun Simiao exchanging opinions with each other with serious faces, the patient's family couldn't help but get nervous.

After discussing with Li Chong, Sun Simiao replied: "The problem, it is indeed a bit serious, your father's illness is actually called high blood pressure, usually it doesn't seem to be a big problem, but if it really comes to the onset of the disease, it will be very troublesome, next, I will prescribe some medicine for your father, and then every day later, we will come to see again, besides, during this period, you can't let your father drink again." Meals should not be eaten too salty, especially some salted ones, which should never be eaten. In a month, we'll see the results. ”

After that, he went to write down the prescription for the other party.

Of course!

In fact, Sun Simiao is also a little curious, that is, why can't patients with high blood pressure eat things that are too salty? This made Sun Simiao very puzzled, and when he looked at Li Zheng's answer, Li Chong also pretended not to see it. In the end, I really had no choice but to say: "This is all a summary of experience." The amount of salt eaten is directly proportional to the probability of developing high blood pressure. ”

"What does this mean?"

"It's a mathematical term, simply put......"

Yan Lide didn't expect that Li Chong would know so much.

Li Chengqian returned to the temple and saw that his teacher was gone, so he immediately asked the guards, "Where is my teacher?" ”

The guard replied, "Master Li asked me to tell His Royal Highness the Crown Prince that he went to Doctor Sun. ”

Li Chengqian let out an 'oh'.

I just wanted to sit down and read a book, but I don't know why, I'm still a little worried, after all, what if the teacher gets lost.

Then, he also followed Sun Simiao's house.

Later, I heard Sun Simiao's disciple say that Li Chong went out with Sun Simiao, and he was in a hurry.

It's really not a second to see the teacher, and he's uncomfortable.

It wasn't until he saw Li Chong, Sun Simiao, and Yan Lide coming back together that he happily greeted him.

"Teacher, Doctor Sun."

Only forget about Yan Lide.

Of course, Yan Lide has not forgotten Li Chengqian.

"The minister has seen His Royal Highness the Prince."

"No courtesy."

"What did the teacher do today?"
