Chapter 127 – The First Case Of Intravenous Injection In Ancient Times

Chapter 127 The first case of intravenous injection in ancient times

Although Xu Yun had controlled Wang Yue’s injury by means of external application not long ago, it was only a temporary measure.

Things to say.

This is only a highly effective but short-term effect achieved through the special effects of allicin and the close to zero drug resistance of Wang Yue, an ancient man. .

That is, as the saying goes, ‘hanging your life’.

Right now, the first batch of garlic juice prepared by Xu Yun has all run out, so intravenous injection has become a top priority.

However, considering that the red sea urchin used to make needles is not a common ingredient—or a common medicinal material in this era, you need to go to major pharmacies and the square market in Bianjing City to find it. It is estimated that it is difficult to find the real thing today.

Therefore, Xu Yun could only take out part of the allicin solution first, and continued to resuscitate Wang Yue through external application.

After doing these things, while there was still time, he fiddled with the plating solution for the needle.

That is.

silver.

Actually.

Xu Yun’s initial plan was to use aluminum as the needle plating solution.

However, according to the normal historical timeline, aluminum will not be officially produced until 1827. Before that, metal aluminum was quite rare.

It’s not that Xu Yun can’t continue rubbing his hands, but the process of preparing aluminum metal is very troublesome, and the complexity is even more difficult than that of microscopes and generators combined.

Wang Yue’s illness obviously cannot last that long, so Xu Yun finally decided to use silver to prepare the plating solution.

Anyway, the plating solution only needs to ensure that the upper part of the sea urchin spines will not be broken by the elasticity that penetrates the skin.

Even if some silver enters the human body through the breach, this dose will not pose any threat to the human body at all.

At most, some protein around the wound has deteriorated, causing the scab to appear darker.

The melting temperature of silver is 961 degrees, which belongs to the temperature range that can be easily reached in ancient times, and it is not difficult to prepare.

Therefore, Xu Yun didn’t show off his skills too much, but simply made a small stove similar to a coal kiln with clay, and increased the melting efficiency through pressurization to ensure that the silver nuggets can be melted into liquid as soon as possible.

As for the silver used in the plating solution.

Of course I got it from Lao Su.

After preparing these.

Xu Yun handed over the scene to a servant, and moved himself.

That’s right.

move place.

Mentioned earlier.

Currently, Xu Yun has entered the roster of diners, completely out of slavery, and has become a standard ‘guest’.

Therefore, his residence was naturally changed from the South Wing to the East Wing, which can be regarded as a promotion and salary increase in the ancient sense.

Compared to the humble south wing, the east wing is much better.

For example, the room Xu Yun was assigned to was about 20 meters away from the courtyard where Wang Yue was, and it was a small courtyard with a single family.

Not to mention anything else, the area of the courtyard alone is about 30 square meters.

A big willow tree was planted in the front of the courtyard, and it was extremely cool under the shade.

On the left side of the willow tree, there is a small pond with a square meter, in which several fish are swimming leisurely.

On the right side of the willow tree is a grape arbor, and under the arbor is a reclining chair—that is, the old-fashioned chair of later generations.

Wait until the sun goes down, call the servants to cut some pieces of fruit, and burn a pot of fragrant tea.

Leaning leisurely on the chair and watching the night scene, it feels very comfortable.

Other than that.

The decoration in this room is also much better than that in the south wing.

For example, there are desks, inkstones, and incense altars in the house, and there are various carved patterns beside the bed.

Throughout the day today.

Xu Yun not only rubbed the generator with his hands, but also tinkered with electrolysis, using the corrosiveness of hydrochloric acid to open the door to the microcosm for Lao Su.

Physical strength is okay, but the loss of energy is really not small.

In addition, after moving home, the time has come to Xu time, which is more than eight o’clock in later generations.

So after a simple dinner, Xu Yun lay on the bed and fell into a deep sleep.

Still nothing to say all night.

Perhaps it was because of a better bed, Xu Yun slept quite soundly this time, and woke up naturally the next day.

That’s right, no one woke him up today.

“what”

Seven or eight o’clock in the morning.

Xu Yun stretched his waist and woke up leisurely.

Then he got up and put on his new clothes—these were the commoner clothes that the old Su sent people cut for him yesterday, or the low-key and common gray style.

But the fabric is infinitely better than the original Tsing Yi.

After wearing.

Xu Yun walked to the sink by the door, and turned a switch similar to a faucet.

Less than a moment.

Clatter—

A gust of cool well water gushed out from it, gradually filling the washbasin.

Xu Yun washed his face with these waters, opened the door, and planned to look for Lao Su.

As a result, I just walked a few steps.

A timidly familiar voice came from my ear:

“Brother Wang Wang.”

Xu Yun followed the trend and found another acquaintance standing outside his door:

“Huh, third brother?”

That’s right.

It was Zhang San who came.

From the address in the little boy’s mouth, it is not difficult to see that Yong Zhu probably explained something to him.

Then Xu Yun walked quickly to Zhang San’s side, and patted his gray-stained shoulder without any scruples:

“Third brother, where have you been these days? I haven’t seen you yet.”

Seeing that Xu Yun’s attitude towards him was the same as before, Zhang San’s expression gradually relaxed a bit.

Of course.

There is still some restraint, but it is not as outrageous as a pathetic thick barrier:

“My sister’s child was full moon yesterday, I went to help my brother-in-law’s house to arrange some things, so I asked for a few days off

Wang. Brother Wang, I heard that you made meritorious deeds in front of the master, and you moved to Dongyuan all at once? “

Xu Yun nodded to him and hummed.

Zhang Sanben is a child at heart, and he has never seen what he did in the past two days.

So it’s no surprise.

Most of the “comfortable and meritorious service” in his words are what he heard from other servants.

After all, I was a thief who was just fished out of the water a few days ago, and became the lowest servant the next day, just an ordinary unlucky guy.

The result is less than a week away.

I turned into Lao Su’s guest, and those servants should even call themselves “Prince Prince” according to the normal address.

Except for a young man like Zhang San, most of the servants will inevitably order lemons in their hearts and say something strange.

Then Xu Yun smiled and said to Zhang San:

“It’s just good luck, anyway, whether it’s a doorman or a servant, don’t they all work for the master?”

“No no no, that’s not the same.”

Hearing Xu Yun’s words, Zhang San shook his head seriously, clasped his fingers and said:

“Don’t tell me, Old Duguan and Sister Yuelian, the monthly salary of an ordinary servant is only four to six guan, which is almost at the top.

Kemenke’s offerings are different.

I heard that diners start with at least ten guan, and some even have 20 or 30 guan.

It’s also a one-month job, and the door-keepers can’t beat us for five months! “

Looking at this little boy who had been thinking about monthly money since the first time we met, Xu Yun smiled and rubbed his head, jokingly said:

“Since this is the case, how about if I have the opportunity to teach you a few tricks so that you can also become a disciple?”

According to Xu Yun’s thinking, he and Zhang San are quite destined, and they get along quite well in temperament.

If there is a chance, it is okay to teach him some methods that can “change his life”.

Unexpectedly, Zhang San quietly glanced at Xu Yun’s lower body, and quickly shook his head:

“No, no, it’s fine for me to be a servant. By the way, go and have breakfast, the master seems to have something to do with you.”

As he spoke, Zhang San’s expression became more and more strange:

“It seems that you bought something you wanted, you can poke and cum”

Xu Yun didn’t notice Zhang San’s face at this time, and focused all his attention on his words:

“Good guy, found the red sea urchin in one night? Isn’t this too fast?”

Originally, according to Xu Yun’s idea, red sea urchins are rare in the inland, and most of them can only be found in Dengzhou.

Together with the time-consuming on the road, it will take about three days to guarantee the bottom line.

how to say

Old Su is indeed a person who once became a prime minister.

Even though he has been retired for three years now, some methods are still quite sharp.

He probably used some extraordinary connections to find the red sea urchin that Xu Yun needed in a short time.

In the morning of the East Wing, someone will go to the street to buy it in advance, and there is no need to share it with the servants.

So after filling his stomach, Xu Yun came to the yard where the generator was rubbed yesterday.

I saw this moment.

The generator and electrolytic cell he made yesterday are being placed in a corner, and the simple high-temperature furnace built by hand is smelting silver water—the melting point of iron is 1536 degrees, which is nearly six hundred degrees higher than silver, so don’t worry about the iron pot Melting accidents happen.

Old Su stood beside the generator, seemingly studying something.

Perhaps because he was too involved, he didn’t even notice that Xu Yun had entered the hospital.

Seeing this, Xu Yun made a silent gesture to Zhang San, walked to Lao Su’s side alone, and said:

“Master, I kept you waiting, what are you doing?”

Old Su raised his head upon hearing this, and nodded slightly after seeing Xu Yun:

“Oh, Xiao Wang is here, I’m working on the generator you made.”

Seeing that Lao Su’s expression was a little leisurely, Xu Yun knew that Wang Yue’s condition was probably relatively stable, so he took the initiative to follow along:

“Master, I wonder what you have discovered?”

“It’s not a discovery, it’s just a little income.”

Old Su Chao waved his hand, pushed the generator with his chin, and said:

“The old man has been observing this thing for a long time and found a few details. Come and see if it is correct.”

Xu Yun hurriedly made a listening gesture.

Old Su pointed to the stator part of the generator and said:

“First of all, this loop is connected end to end, forming a loop.

The old man once tried to remove the charcoal, but found that the generator would not work.

So the old man judged.

If you want this thing to work, it must first be a connected and closed inner loop. “

After he finished speaking, he paused, ignored Xu Yun’s expression, but continued:

“Secondly, there is the issue of direction.

Look here, two poles are opposite each other.

If it is according to what you said, everything in the world can be divided into particles.

Then the particles between the magnetic poles must move laterally according to the force of attraction.

But the direction of the turning object inside is very weird:

When it rotates, different positions are in contact with the ‘particles’ of the magnetic poles every moment, as if they are doing friction

Combined with your previous action of letting the donkey pull and suck, the old man made a second judgment that I don’t know whether it is right or wrong.

That’s what you call ‘electric energy’, which is actually the power generated by the donkey pulling the mill, which is produced through the ‘friction’ of the internal transfer object.”

The yard.

Looking at the old Su who was talking eloquently in front of him.

Xu Yun looked calm on the surface, but his heart was involuntarily turned upside down.

Although Lao Su’s statement has many deficiencies, it is estimated that he will be punished to stand in the back row in the physics class of later generations.

But don’t forget.

This is 1100 AD.

A feudal era without even the knowledge of electric energy standards.

Old Su can make this kind of judgment by observing the generator, it’s amazing!

Although Lao Su still has a long, long cognition gap from the real principle of magnetism and electricity.

But his remarks basically outline two key elements of magnetoelectricity:

Closed circuit, the angle between the direction of conductor movement and the direction of magnetic field lines is not 0.

Outside here.

Lao Su’s last sentence even named the essence of magnetism and electricity:

Magnetoelectricity is electric transfer, kinetic energy is converted into electrical energy, making it far away from or close to the charge.

Coulomb force does work and induces current in the conductor.

Let Xu Yunlai flatly comment, Lao Su is simply a .

monster!

That’s right, monster!

Then he took a deep breath and said to Old Su:

“Master, your analysis is very close to the truth of the generator, but the specific concept involves something called electric current. Zhonghou is still sick in bed. Shall we start now?”

Old Su raised his eyelids to look at him, pondered for a while, and asked:

“Xiao Wang, do you know much about electric current?”

“Slightly understand, slightly understand.”

Old Su nodded slightly, keeping this matter in mind, and then said:

“In this case, let’s go and get an intravenous injection for Zhengru first. Look in that box, is it the thorn pot you want?”

Xu Yun followed the trend and looked.

It was discovered that what Old Su was referring to was a wooden water tank about 30 centimeters high.

Then he walked to the water tank and found several red sea urchins were sinking at the bottom of the water tank.

As a doctor of biology and a Japanese food lover, Xu Yun identified the species of these sea urchins the moment he saw them:

no doubt.

It is the red sea urchin!

Once the species is correct, the rest is simple:

I saw that he first removed the spines of one of the red sea urchins, cleaned and disinfected it with alcohol, and then smeared molten silver water on the body surface.

Then take advantage of the time when the silver water condenses, take out 120 mg of the allicin alcohol solution in advance, mix it with 1000 ml of normal saline, and stir well.

that’s it.

A bottle of simple allicin injection is prepared.

Another quarter of an hour passed.

The silver water bath has condensed.

Xu Yun took a silver syringe from Lao Su—this thing is a syringe body made by Lao Su according to the diagram he gave, and there is a buckle-type small switch at the interface.

Xu Yun turned on the switch and put the needle tip in from above the tube.

The needle tip is made into an inverted cone with a thick top and a thin bottom under the infiltration of the plating solution.

Therefore, when the needle tip protrudes from the lower end to about 90%, the remaining thick and impassable part is left in the tube body.

Xu Yun closed the buckle again to fix the needle tip completely.

So far.

An ancient silver syringe is finished.

After finishing these, Xu Yun followed Lao Su into the house.

Wang Yue is still sleeping at this time, but it can be seen from his face and breathing frequency that this Lord Zhonghou is out of danger.

You can even hear a little snoring, obviously dreaming a sweet dream.

Seeing Xu Yun and Lao Su enter the room, Wang Ting, who was accompanying the bedside, quickly got up and bowed to the two:

“Uncle, Xiao Wang, you are here.”

Xu Yun saluted him back, then shook the needle in his hand, and said:

“Master Captain, the injection has been prepared, can we start the injection now?”

Wang Ting quickly gave up his position, his trust in Xu Yun has reached a very high level:

“Please go ahead.”

Xu Yun stepped forward and gave Wang Yue a simple skin test.

Twenty minutes later.

Wang Yue did not show any abnormality in the skin test site.

That is, the skin test is negative, and there is no allergy.

Seeing this, Xu Yun glanced at Lao Su and Wang Bao:

“Master, captain, Zhonghou’s body can receive intravenous injection, so the villain’s side has started?”

Old Su nodded:

“let’s start.”

Xu Yun heard the words and took a deep breath, sucked up the liquid medicine with a syringe, and exhausted the air.

At the same time, tie a simple tourniquet on Wang Yue, and take Wang Yue’s left hand.

Find the vein and apply a bolus.

The spines of the red sea urchin easily pierced Wang Yue’s skin and inserted into the blood vessel.

Xu Yun’s injection speed was very slow, and he was extremely careful throughout the process.

After a few minutes.

After finishing a injection of allicin injection, Xu Yun’s expression did not relax at all.

He knew that now was the most dangerous moment.

Although intravenous injection is a way for antibiotics to take effect quickly, it also comes with high risks.

For example, there may be infusion reactions, and for example, too many drug particles may cause local blockage and insufficient blood supply.

And further lead to tissue hypoxia, edema and phlebitis, etc.

Wang Yue’s only advantage is that he is an ancient soldier.

Physical fitness is much higher than ordinary people, and there is no drug resistance in future generations.

A quarter of an hour passed.

Wang Yue is normal.

Two quarters of an hour.

half an hour

One hour.

Two hours later.

Wang Yue still didn’t show any abnormalities, and Lao Su personally took his pulse, and found that the pulse was stabilizing.

It is clear.

Intravenous injection

succeeded.

Last night, my grandma vomited and had diarrhea, which made the whole family panic to death. I couldn’t sleep all night. Today, my uncle caught a cold.

My grandparents have two sons and a daughter, but my uncle cut off relations with my grandfather because of some things. This time, I can only rely on me, my uncle and my mother as escorts. I don’t know whether to have surgery or not. In this way, living in a homestay in a different place takes turns to accompany me every day. My mother is 60 and my uncle is 57. I can’t bear it, let alone them.

I have to accompany you tonight, so what I said may have broken my promise, sorry everyone
