In the next two days, Qin Qiong's condition got better day by day.

Of course, he had just undergone surgery, and he needed to rest in the hospital bed for the next few days.

But before the operation, Qin Qiong was already in a state of coughing up blood and often in a coma, and in one day, he was awake for one or two hours.

And now, although Qin Qiong's body is weak, her spirit is extremely full all day.

And the miracle doctor Sun Simiao concluded after a follow-up examination of Qin Qiong's pulse that after ten days later, General Qin's body could slowly recover after the stitches were removed.

After half a year of recuperation, although I dare not say that I can return to the health status of a normal person, there is no problem in walking around daily to achieve self-care.

After learning the news, everyone in the Qin Mansion cried with joy, and Qin Huaiyu even knelt down to thank him.

Even Li Shimin called Li Su and asked about the blood transfusion and the fever.

Because Li Shimin realized a huge problem, if the problem of blood transfusion and fever reduction could really be solved, then in the future, on the battlefield, Datang could die thousands or even more soldiers.

Because of the casualties on the battlefield, unless it is a decisive battle between the two sides that bet on the fortunes of the country, the soldiers who really die on the battlefield only account for a very small number of casualties.

The vast majority of soldiers die from blood loss and wound inflammation after being wounded.

Once these two problems can be solved, the casualty rate of the Datang soldiers will be greatly reduced, and the combat effectiveness of the Datang army will be increased by at least three percent or more.

Therefore, Li Shimin attaches great importance to this issue.

However, Li Su really can't solve this problem at present.

Because blood transfusion requires blood bags, needles and other equipment, as well as antipyretics, Li Su purchased them directly from the mall.

But the price is terrifyingly expensive, if you want to use the method of buying from the mall to meet the needs of the entire Tang army, Li Su can't afford to buy so many utensils even if he falls asleep and loses his body.

And if you produce it yourself, the recipe alone is an astronomical amount of 10,000 losers.

Of course, in fact, this price is relatively speaking, and it is really not expensive.

Because this is definitely a huge profit, the benefits are amazing, if it can really be mass-produced, it is definitely a hundredfold and thousand-fold profit.

It's a pity that Li Su's current loser value is not enough at all.

Moreover, these utensils also have antipyretics, which may not only be produced if you have a formula, but also some advanced processes in them, which may not be possible at all in this era.

Therefore, Li Su could only answer euphemistically that this kind of thing is expensive to build, and there is no possibility of mass production at present.

Li Shimin looked extremely disappointed, but he was helpless.

……

After coming out of the palace and just returning to King Liang's Mansion, Xiao Liuzi came over to report that it was the divine doctor Sun Simiao, who had been waiting for him at home for a long time.

The divine doctor Sun Simiao actually came to visit this palace, and he actually waited for a long time?

Li Su was a little puzzled at first, but soon guessed why Sun Simiao came.

If nothing else, it must have been due to blood transfusions and fever, right?

However, I really can't get these instruments out of my hands now.

However, soon Li Su thought of a question, and his face couldn't help but show a thoughtful look.

After coming to the living room, they greeted each other and exchanged a few words, and as Li Su expected, Sun Simiao made his request to Li Su.

"Your Highness, can you ask Your Highness if you still have a fever problem with blood transfusion? If these two problems can be solved and put into use, it will be able to save thousands of people of the Tang Dynasty, and please ask Your Highness to fulfill it. ”

Li Su nodded and said: "Sun Shen Doctor Qi Huang Holy Hand, with the ambition of helping the world and saving people, His Royal Highness admires it." In fact, this blood transfusion method is still very easy to implement as long as the patient's blood type is figured out. ”

"There are about five blood types in the human body, and the most common blood types are named blood type A, blood type B, blood type A and B and blood type C. There is also a very rare blood type, which may only have a few in 10,000 people, which can be called yin blood. ”

"Normally, there is basically no problem with transfusions of the same type of blood. If the same type of blood cannot be found, then, in principle, blood type C can be transfused for all blood types. For blood type A and B, blood transfusions of all blood types can be accepted. ”

"Of course, it's best to focus on blood transfusions between the same blood type. In addition, even if it is the same blood type, a hemolysis test is required before blood transfusion. That is, before the blood transfusion, a few drops of the blood of the two people should be taken together to see if there is any clotting. If not, a blood transfusion can be performed. ”

Hearing Li Su's words, Sun Simiao's eyes couldn't help but light up, and he immediately took out a pen and paper and quickly recorded what Li Su said.

Whether there are any questions written down in the middle, I kept asking Li Su until there was no omission.

After it was completely recorded, Sun Simiao asked again: "Your Highness, how can you distinguish these four blood types?" ”

"The question ......"

How to distinguish the four blood types, in modern times, you can go to the hospital to buy anti-A serum and anti-B serum.

But as for how to make these two serums, Li Yu is not clear.

After all, he didn't study medicine, and he didn't have access to this kind of knowledge on a daily basis.

If someone else asked this question, Li Su would definitely avoid talking about it.

But the person who asked was Sun Simiao's words, in order to arouse Sun Simiao's enough attention, Li Su decided to answer this question.

It doesn't matter if you don't know the answer, he has the system.

Li Yu spent ten loser values to buy the method of making serum from the system, and after checking it, he couldn't help but curse the system in his heart, it's really black!

"If you want to distinguish these four blood types, you must first extract anti-A serum and anti-B serum. Anti-A serum should be extracted from blood type B. First, take some blood type B, then let it sit for about half an hour, and the blood will clot. The clear fluid above the blood is the anti-nail serum. ”

"And anti-B serum is also extracted in the same way. After the two types of serum have been extracted, the patient's blood type needs to be tested, and two drops of his blood can be taken and dripped into each of the two serums. ”

"If only antithyroid serum is coagulated, then his blood is blood type A. Only anti-B coagulation, blood type is blood type B. Both types of serum are coagulated, which is blood type C. If neither blood type is coagulated, it is blood type A and B. ”

When Li Su was explaining, Sun Simiao was recording quickly, and after the recording, his face couldn't help showing ecstasy. 、

This method of blood transfusion is tantamount to pushing open a door in front of Sun Simiao's eyes.

And as long as the method of blood transfusion can be applied to the treatment of diseases, countless people will be alive.
