The sight was blocked tightly all of a sudden, and Dong Muqing pursed the corners of his mouth.

I hesitated in my heart whether to give up the dignity of your son, and learned from that group of people to go over and watch...

"Ahem..."

Dong Shicheng is also extremely curious about the method of blood transfusion, if this method can really save people, then it must be promoted...

But before he could see Yun Niangzi's operation clearly, he was strictly blocked from view.

Still, ginger is old and spicy.

"Everybody's gathered around here... It's not good for the treatment of the patient..."

Dong Shicheng frowned, and his disapproving gaze slowly turned around the circle of onlookers.

As soon as the voice fell, Si Mo's cold voice followed.

"Except for the six people just now, everyone else left!"

He didn't like the way their gaze stayed on Yun Shu, so he couldn't help but want to kill.

Yun Shu can only be his!

In Wei County, Simo's words are the holy decree.

The officials present don't care if they belong to that camp, but on the surface, they must listen to Si Mo's words.

His eyes suddenly widened, and Dong Muqing straightened his back elegantly.

His grandfather is indeed his grandfather...

Yun Shu ignored the people who went out, turned his head and used scissors to cut the clothes on Dou Dian's shoulders.

"The arrow is still inside, how do you take it out?"

"This..."

The old doctor looked at it carefully for a long time, "The arrow is stuck in the bone, and if you want to take it out, you have to cut the flesh..."

"Then cut away!"

Yun Shu nodded, and directly stuffed a scalpel into the old doctor's hand.

"Here you go!"

"Oh..."

The old doctor took the scalpel in a daze, and gestured horizontally on Dou Dian's shoulder for a long time, but he didn't fall off the knife.

Yun Shu's gaze fell on the old doctor's hand, and he frowned, "What's the problem?" ”

"None..."

The old doctor smiled a little wryly, "I'll get used to it..."

This knife monster is pretty...

It turns out that scalpels don't just look good, they work better.

As soon as the knife went down, the old doctor's eyes lit up.

"Madame... This thing..."

Yun Shu didn't raise his head, staring at Dou Dian's wound with a solemn gaze, "I've sent you!" ”

"Huh? Good! ”

The old doctor was ecstatic, and his subordinates were a little more stable.

Within moments, he had taken out a blood-stained arrowhead.

"Stitch it up first!"

Yun Shu stopped the old doctor's hand that he wanted to bandage directly, and handed him a medical suture needle.

"What?"

The old doctor blinked vigorously, as if he didn't hear Yun Shu's words clearly.

Sewing what?

Meat is not clothing, can it be sewn?

"Use this needle to stitch up the wound! Sewing clothes, right? Just press that seam! ”

Yun Shu can only do simple first aid, and she naturally can't suture this kind of professional technique.

Looking at the old doctor's appearance, he won't either.

However, sewing a wound should be similar to sewing clothes, right?

"The wound is too big, and if it is simply bandaged, the wound will heal slowly, and the bleeding will not stop all at once..."

"But if we sew up the wound with thread, won't the wound not be easy to open?"

Yun Shu picked what he knew and briefly explained a few words to the old doctor.

"Let's try?"

"Try..."

The old doctor's face gradually became solemn, and what Madame said was very true!

It is true that such a large wound is extremely difficult to heal, and even if it is bandaged, the wound will collapse with a slight movement.

However, if it is sewn with a thread, it will not interfere with simple daily activities and will allow the wound to heal faster...

The old doctor took the needle and thread handed over by Yun Shu, followed the example of his wife mending clothes, and sewed a big ugly scar crookedly.

The corners of Yun Shu's mouth twitched slightly.

He might as well do it herself!

After bandaging the wound, Yun Shu took the blood of several more people, and gave it to Dou Dian.

Five bags of plasma went down, Dou Dian's face was visibly ruddy, Yun Shu measured it with a blood pressure monitor, and his blood pressure had stabilized.

"I think it's been saved..."

Yun Shu breathed a sigh of relief.

The old doctor hurried up and felt his pulse, "The pulse has recovered!" The man was really saved..."

"It's a god!"

"The method of blood transfusion is so magical..."

The grandfather and grandson of the Dong family glanced at each other, and once again their eyes fell on Yun Shu who was not far away.

Since Yun Niangzi is willing to say the method of blood transfusion in front of so many people, she must want to promote this method...

At a time when everyone is trying their best to hide their craft or technology, she actually wants to promote it!

This woman's open-mindedness is really comparable to that of a man...

"Madam, this method of blood transfusion..."

The old doctor's excited hands had nowhere to be placed, and he wiped his hands over and over again on the hem of his clothes.

I can't wait to learn this blood transfusion method all at once, and then use it on patients who need treatment...

"Doctor Liu, be safe!"

Yun Shu changed Dou Dian with an anti-inflammatory potion, and then stood up and looked at Dr. Liu.

"The method of blood transfusion is actually very simple, it is to use this infusion tube to transfuse blood for people who are ischemic."

"However, blood transfusion must be transfused with blood of the same blood type, otherwise blood transfusion will not save people, but harm people!"

"Blood types vary from person to person, and generally according to ABO classification, people's blood types are divided into four blood types: A, B, O, and AB."

"But there are also special blood types, such as RH typing, which divides blood types into RH positive and RH negative."

"Of course, most people have ABO blood types, and only a few people have very special RH types."

"So before the blood transfusion, the blood type must be determined, and blood transfusions between different blood types cannot be carried out..."

Yun Shu took out a blood group test paper from the medicine box, "This is the equipment for testing blood type..."

"This can only be used to detect ABO blood type, special blood types need other testing tools..."

Yun Shu simply popularized the use of blood group test paper to Dr. Liu.

"Once the blood type is determined, this infusion tube will also be used..."

"This kind of thing can't be mass-produced, so the method of blood transfusion still can't be popularized throughout the country..."

For this Yun Shu is also very helpless, it is simply impossible to produce this kind of infusion tube in ancient times.

Unless the system rewards her with a complete production line, she has to bring her own power plant!

The climbing of the technology tree has to come step by step, and countless basic technologies and basic materials have to be studied one by one.

Instead of thinking about making it yourself, you might as well buy it directly from the system mall!

Anyway, this thing is very cheap, and you can buy a lot of it for ten points...

Hearing that there were so many restrictions on blood transfusion, not only Dr. Liu, but also everyone present was a little disappointed.

"However, if it can't be used in other places, it doesn't mean that it can't be used in Wei County!"

Yun Shu smiled mischievously, "After I sort out the blood transfusion method and other first-aid methods, it will be promoted throughout the county, so Dr. Liu doesn't need to worry." ”

Wei Jun has her, and she can supply unlimited medical equipment such as blood group test paper and infusion tubes, but she can't do anything else!

"That's good!"

Dr. Liu's heart fluctuated and grunted like the wind.

He is a pure doctor, and all his life has been thinking about how to cure diseases and save people, so he is naturally particularly interested in ways that can save people.

"Ma'am, he's awake..."
