Into Unscientific Chapter 122

  Chapter 122 Intravenous injection can also be done in ancient times (still a joint chapter)

   "Intravenous?"

  Hearing the word that came out of Xu Yun's mouth, Lao 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 traditional 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.

   Meridians Meridians.

   is actually the concept of blood vessels defined by modern medicine.

   But some people are against it.

  They think that the meridian is the passage of Qi, which is invisible to the naked eye, but it just 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.

  Acupoints 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 you have something 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.

  Many times, if a person is uncomfortable, pressing these acupoints can give quick results.

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

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

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

  In 2019, ScienceAdvances 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 conclusive. 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, and it is unnecessary and impossible to 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.

  Current science can't even explain why a bicycle doesn't fall on both sides after riding it.

  Related papers were published in the main journal of "Science" at the beginning, 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)

  Some 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 meridians exist or not, in the "Huangdi Neijing", the ancient ancestors already had a certain understanding of anatomy.

  So 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.

  The drug can reach the affected area directly, which is better than oral and external application. "

  Old Su couldn't help lowering his head when he heard the words, 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, oral administration, subcutaneous injection, and intramuscular injection are not only ineffective, but also easily cause 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, 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.

  I saw him pondering 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.

  However, inject garlic juice into the so-called vein, and reach the affected area through the cycle of the sky. This old man has never heard of it.

  Xu Yun, let me ask you a question.

  If drugs can really be injected into the human body to take effect, then what should be used to accomplish this? "

  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?

   Still doing real poking?

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

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

   Hiss!

  Think here.

  Old Su looked at Xu Yun with something wrong:

  That Wind Spirit Moon Shadow Sect, could it be that he was from the Hehuan Sect?

  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 foot long.

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

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

   "Main body? Front needle?"

  Listening to 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.

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

   But it's rudimentary and rudimentary, and some key details are barely described.

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

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

  The 'tube body' of the syringe is actually made of sheep bladder, and then the pipe is made of 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 the local history, the real 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 artifact, 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 who can tinker with the self-priming pump.

  So 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 shot into the human body with the momentum of crossing the mountain.

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

  Students who have taken the history of physics in ancient China during their doctoral period should know it.

   Over the mountain.

   This word is actually the embryonic form 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 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 theory.

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

  After thinking about it, Old Su 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 to prepare this needle?

  According to what you said, the needle 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 prickly pot?"

   "Prick the pot?"

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

   "It's that kind of sea creature covered in thorns? I've seen it a few times

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

  Xu Yun nodded heavily:

   "Yeah, that's it."

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

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

  In recent years, sea urchins can be seen in both Chinese cuisine and other countries' cuisine.

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

  However, in ancient China, sea urchins were only used as medicinal ingredients, and did not appear 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 dinosaurs appeared, 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 the most popular products, long-spined sea urchins grow the fastest, and red sea urchins are the least common in the market.

  Another point 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.

  Spines of sea urchins are columnar protrusions formed by calcification of connective tissue, which communicate with the poison 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 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 produce 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.

  There are quite a few sea caravans traveling between Goryeo and Tamna these days, and there are fewer fishing boats. However, some rare sea goods will always be brought back to 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.

  So as long as you spend some time looking for it, it is not difficult to find some red sea urchins.

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.

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

  Find the red sea urchin, reinforce the 'needle' with aluminum, and prepare saline.

   Exactly.

  Normal 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 be incorporated into the rehydration solution or liquid preparation before the next 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 internal and external imbalance of cells in the blood will be caused, and cell rupture will occur.

  The osmotic pressure of the 0.9% sodium chloride used for infusion is similar to that of blood, and the infusion of this liquid will not cause a large change 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 "whoami", 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 writer friend whose pen name was the Bachelor of Wet White Clothes at Auntie Point.

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

  Exquisite medical skills, extremely high hairline.

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

   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.

  So after careful consideration, Xu Yun finally planned to make simple saline solution.

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

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

Of course.

   Xu Yun plans to make the salt needed for this part—or sodium chloride.

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

   For example, 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, ahahahahahaha!

   Grandma is in a bad situation. Hey.
