Into Unscientific

"Intravenous?"

Hearing the word that came out of Xu Yun's mouth, Old Su blinked blankly:

"Wang Lin, what is that?"

Xu Yun thought for a while and explained:

"Master, whether it is a human body or a livestock, there are blood pipelines in the body, you should be aware of this, right?"

Old Su didn't hesitate much this time, and nodded:

"Of course."

In ancient China or the concept of Chinese medicine, blood vessels and meridians should be regarded as a very easy to cause controversy.

There is a standard interpretation of the description of meridians in traditional Chinese medicine, which is "a few inches under the skin, which can ventilate qi and blood".

Therefore, some people think that meridians are the main blood vessels, and collaterals are capillaries.

Meridian Meridian.

In fact, it is the concept of blood vessels defined by modern medicine.

But some people are against it.

They believe that the meridian is the passage of Qi, which is invisible to the naked eye, but it happens that some positions coincide with the blood vessels.

As soon as the issue of meridians is extended, it is easy to be accompanied by further debates about the existence of acupuncture points.

Acupuncture points are the same as meridians, and there is currently no real hammer to discover its existence.

This is also a major reason why many people have a negative attitude towards Chinese medicine. How can you say that you have something that you can't find?

But on the other hand.

Some acupuncture points in life can indeed feel the effect in person.

Such as Zusanli, Fengchi, Shaoshang, Hegu, etc.

In many cases, if people feel uncomfortable, pressing these acupoints can give quick results.

In addition, in recent years, the research on meridians has more or less produced some results.

For example, at the end of October 2021, Harvard University published a successful case of electroacupuncture stimulating the Zusanli acupoint of animals in the treatment of sepsis in "Nature".

Paper code doi.org/10.1038/s41586-021-04001-4.

In 2019, Science Advances also published a research report on acupuncture points, DOI: 10.1126/sciadv.aax1342.

all in all.

At present, the meridians and acupoints in traditional Chinese medicine have not been determined. After more than ten years of related research, there is still no accurate statement on the specific location of the meridians.

This is a fact, there is no need and cannot deny it.

But again.

The real effect of some acupuncture points is also obvious, which cannot be ignored.

The current scientific theory is still in development, and there is still a long way to go.

To put it bluntly.

The current science can't even explain why the bicycle doesn't fall on both sides after riding it.

At the beginning, relevant papers were published in the main journal of "Science", and the influence of this paper lasted for nearly ten years, DOI: 10.1126/science.1201959. (It’s not me fooling you, it’s true, if you are interested, you can search it)

Certain technological developments and scientific explanations of certain phenomena are two different things and cannot be generalized.

The line of sight returns to reality.

Regardless of whether the meridian exists or not, in the "Huangdi Neijing", the ancient ancestors already had a certain understanding of anatomy. This is a well-documented record. After all, you can see blood vessels even if you kill a chicken.

Therefore, after Xu Yun mentioned the concept of blood vessels, Lao Su easily accepted this concept.

Then Xu Yun paused and continued:

"A vein is a thick, large-capacity blood vessel that collects return blood to the heart.

It is an important channel to complete the body circulation, which is the daily circulation of the human body.

Intravenous injection refers to the injection of diluted and prepared garlic juice into the human body through special utensils.

In this way, the medicine can directly reach the affected area, which is better than the effect of oral administration and external application. "

Old Su couldn't help lowering his head when he heard this, and touched the veins on his hands.

In modern medicine, injections mainly include subcutaneous injections, intravenous injections, and chicken and intramuscular injections.

Due to its chemical properties, allicin is not only ineffective when taken orally, subcutaneously, and intramuscularly, but also easily causes harm to the human body.

Therefore, in modern medicine, the main injection method of allicin is basically intravenous injection.

However, there are not many allicin injections on the market at present, there are only about three or five, and capsules are generally the main ones.

As an outstanding scientist in this era, Lao Su naturally has no shortage of creativity and receptivity.

After receiving Xu Yun's suggestion, some records quickly came to mind.

He pondered for a moment, then said:

"I remember that in the "Three Kingdoms" written by Chen Shou in the Western Jin Dynasty, there was a record that a doctor with no surname once scraped the bones of Guan Gong to cure poison.

In the Lingshu Chapter of the "Huangdi Neijing", there are also records of ancestors prescribing phalangeal dressings.

But the garlic juice is injected into the so-called veins, and reaches the affected area through the circulatory cycle. This old man has never heard of it.

Xu Yun, let me ask you this old man.

If it is true that drugs can be injected into the human body to take effect, then under what guise can this be done? "

Xu Yun thought for a while, and drew a shape with his fingers:

"A long, thin, hard thing called a syringe."

Old Su was taken aback for a moment.

long?

thin?

Hard?

Do you really poke?

Could it be that I heard it wrong before, that process is actually called stem vein injection, and the perineum is used?

True stabbing, stem veins, combined with Xu Yun's background as an actor.

hiss!

Think here.

When Old Su looked at Xu Yun, something was wrong with his gaze:

That Fenglingyue Shadow Sect was from the Hehuan Sect, right?

At this time, Xu Yun didn't notice the abnormal expression of Lao Su, but picked up the pen and drew a simple picture on the paper:

"This object is divided into the main body and the front needle, the main body is about half an inch wide and half a chi long.

The front needle is only a few centimetres, hollow inside, and there is a pullable object on the main body.

When it is filled with liquid, just insert it into the vein and push it slowly to inject garlic juice into the human body. "

"The main body? The front needle?"

Hearing the picture drawn by Xu Yun, Old Su was taken aback for a second, before realizing that he seemed to be thinking wrong.

He coughed slightly in embarrassment, and looked at the picture drawn by Xu Yun.

After time travel, the halo endowed Xu Yun with the ability to understand ancient Chinese, but it did not allow him to touch writing and painting. Therefore, this schematic diagram drawn with a brush has the flavor of a soul painter.

But the rudimentary is the rudimentary, and some of the more critical details are barely described in place.

In fact, in ancient China, the ancestors did not try to make syringes.

But the appearance of the needle barrel at that time was very different from that of later generations:

The 'barrel' of the syringe is actually made from a sheep's bladder, and the pipe is made from animal intestines.

It's more like a squeezer for blood pressure than a syringe.

As for this ancient syringe, it is made of bird bones, and the inside is hollow, so it is quite convenient for infusion.

Although this thing is a little thinner than the ancient artificial needles, it still hurts very, very painful.

In native history, the truly modern concept of the syringe was not proposed until the 15th century by Catinel of Italy.

And it wasn't until 1853 that the Gaul Pravas invented the plunger hypodermic syringe, which was made of sterling silver.

Therefore, the syringe painted by Xu Yun can be said to be a new utensil, which is a bit ahead of the ancients.

For the vast majority of people, they may not even understand what this is.

But don't forget.

The principle of the syringe is actually very similar to the air pump, and Lao Su is a master at tinkering with the self-priming pump.

Therefore, within a few seconds before and after, he clapped his hands lightly and figured out the working principle:

"Wonderful, wonderful, the air is sucked in by pulling, and then it is shot into the body with the momentum of crossing the mountain.

Such an exquisite creation, even if Hua Tuo Bian Que is alive, I am afraid that he will be very happy, right? "

Students who have taken the history of physics in ancient China as a Ph.D. should know it.

Over the mountain.

This word is actually the prototype of the ancient understanding of air pressure.

However, at that time, human beings did not have a deep understanding of air pressure. The concept of crossing mountains refers to the valley wind.

Although in the strict sense of this thing, it is related to thermal circulation, not atmospheric pressure in a broad sense.

But considering the limitations of the background, it is actually quite remarkable to be able to realize this at the level of ancient scientific theories.

We must know that Europe at this point in time is still the Middle Ages, and the cognition of wind over there is still the touch brought by the soul of the dead.

Then Old Su thought about it, and said to Xu Yun:

"Wang Lin, the old man has a vague understanding of the principle of this thing, and the barrel is not difficult to make, but how should the needle be prepared?

According to what you said, the needle head is only a little thicker than a hair. If it is a solid needle, it is not difficult. The old man has this kind of silver needle in his hand.

But if the inside is hollow."

Looking at Lao Su who was curious about the baby, Xu Yun smiled slightly at him:

"Master, do you know the thorn pot?"

"A thorn pot?"

Old Su's expression was taken aback, and he blinked quickly:

"It's that kind of thorny sea thing? I've seen it a few times.

Wait, I see. Are you planning to use its thorns as needles? "

Xu Yun nodded heavily:

"That's right, that's it."

Thorn pot, also known as sea urchin in later generations.

Sea urchins can be said to be found all over the world's oceans, whether in Asia or Africa.

In recent years, sea urchins can be seen no matter in the cuisines of our country or other countries.

In the mouths of some gourmets, sea urchin is also regarded as the ultimate delicacy among seafood.

However, in ancient China, sea urchins were only used as medicinal ingredients, not as common ingredients.

Only extremely poor fishermen eat sea urchins when they lack food.

Many people don't actually know.

Sea urchins existed on the earth long before the appearance of dinosaurs, and the history can be said to be quite long.

Of course.

There are still some differences compared with cockroaches.

Currently, there are five types of sea urchins:

Dung sea urchin, purple sea urchin, northern purple sea urchin, red sea urchin, long spiny sea urchin.

Among them, dung sea urchins and purple sea urchins are considered to be high-end goods, long-spined sea urchins grow the fastest, and red sea urchins are the least common in the market.

Another thing that many people don't know is that.

The spines of sea urchins are actually a kind of natural needles.

Or to be more precise.

It should be said that the spines of red sea urchins are a kind of natural needles.

The spines of sea urchins are columnar protrusions formed by calcification of connective tissue, which communicate with the poisonous glands in the body and can easily pierce human skin.

When the spines penetrate the skin and inject venom, it can cause dermatitis and other associated symptoms.

Almost every year, a large number of questions about "how to deal with being pricked by sea urchins" appear on the Internet, especially in some coastal cities.

Most of the medical needles in later generations are 5.5-7 gauge, with a diameter of 0.30mm-0.51mm.

The tip of the red sea urchin thorn is about 0.38mm-0.42mm, which belongs to the standard model for intravenous injection.

Therefore, in ancient times when there was no technology to make sharp hollow needles, sea urchin spines were undoubtedly the best choice.

Although red sea urchins are mainly distributed in neon, the maritime trade in the Song Dynasty was quite prosperous, and it even became one of the pillar industries in the Southern Song Dynasty.

These days, there are many sea caravans traveling between Goryeo and Tamna, and there are fewer fishing boats. However, some rare seafood will always be brought back to the Song Dynasty.

Bianjing, as the core city of the Song Dynasty, sucked blood and coughed, and its blood supply was even more powerful than that of Yanjing in Hebei in later generations.

Therefore, it is not difficult to find some red sea urchins as long as you put in some effort to find them.

Of course.

Although the spines of sea urchins are easy to break through the human skin, they are also extremely fragile, and may break into several sections with a little force.

So before the formal injection, there are two things that need to be dealt with:

Find red sea urchins, reinforce the 'needle' with aluminum plating, and prepare physiological saline.

That's right.

saline.

After all, unlike oral administration and external application, intravenous injection does not mean that as long as the liquid medicine is poured into the tube, it can be directly poked into the blood vessel.

Before intravenous injection, the medicinal solution must first be incorporated into the rehydration solution or liquid preparation before the next step of injection can be performed.

As for the principle, it is very simple, it is related to osmotic pressure:

Human blood has a certain osmotic pressure because it is not pure water and contains various substances.

If the osmotic pressure changes, the inside and outside of cells in the blood will become unbalanced, and cell rupture will occur.

The liquid osmotic pressure of 0.9% sodium chloride used for infusion is close to that of blood, and using this liquid for infusion will not cause great changes in blood osmotic pressure.

Similar to 5% glucose solution, the biology teacher should have talked about it countless times in class.

In some special cases, coconut water can also have this effect.

In addition, in the movie "who am i", the driver was bitten by a poisonous snake, and Uncle Long used coconut instead of glucose to infuse him.

However, when Xu Yun was writing a book in his previous life, he once asked a friend of the writer who had a pen name of Auntie Point Wet White Clothes Bachelor.

In reality, this person is also a physician who is about to become a director.

Excellent medical skills, extremely high hairline.

Therefore, in Xu Yun's writer group, everyone would go to him for consultation and get a free director account if they have anything to do.

At that time he told Xu Yun.

Although there are examples of coconut water injections, this practice is very risky, and readers are not advised to use it after time travel.

Therefore, after careful consideration, Xu Yun finally decided to make simple saline solution.

Although at the current level of technology, it is difficult to produce saline with an accuracy of 0.9%.

But in an emergency, normal saline is already the best solution.

Of course.

The salt needed for this part—or sodium chloride, Xu Yun planned to make it himself.

As for the method is not complicated, there are many kinds that Xu Yun can think of.

Like if you have hands.

Hand rub a disc generator.

Note:

Someone actually guessed the needle, the reader really is Crouching Tiger, Hidden Dragon. I underestimated you heroes.

But fortunately, I didn't add more rewards, I'm so witty, ah ha ha ha ha ha ha ha!
