The great development of sports in Taoqiu, as well as the development of Taoqiu's industry, have made the entire Taoqiu disability accidents continue to increase, and the construction of qualified hospitals has become the most serious problem in front of Dai Yan. Pen, fun, pavilion www. biquge。 info

The medical system in Dai Yan's hands has actually taken shape very early.

When Dai Yan was in Fengyi and defeated Yanglingjun, although he won neatly, he also caused a lot of casualties in Fengyi. At that time, Dai Yan handed over the wounded soldiers to the villages of Fengyi to help take care of them. After the end of the war, he also sent special personnel to provide medical care to them.

Later, when he led the army on an expedition to Vietnam, he found out how much a qualified medical system could help the army and even maintain the morale of the soldiers! On the battlefield, after the soldiers are injured, in fact, as long as they carry out simple first aid, the casualties of the soldiers can be greatly reduced! This is extremely important to maintain the high morale of the entire army!

Therefore, after Dai Yan returned, he set up a simple medical team in the army to be responsible for medical problems in the army.

Later, he even wanted to extend medical services to the whole of Fengyi, but the subsequent breach of contract by the state of Chu and the incident of the soldiers of the state of Qi coming to Taoqiu made Dai Yan have to run around, and the idea of establishing a medical service system came to an end.

And when he sealed Taoqiu, the scale of Taoqiu's city also expanded, and the health and medical problems of the whole Taoqiu were very prominent. Dai Yan knew very well that once a large-scale plague broke out in the city of Taoqiu, then there was no need for foreign enemies to invade, and the entire city would probably collapse immediately!

To this end, he established a health bureau dedicated to the maintenance of the city's appearance in Taoqiu. However, in Dai Yan's view, the most important task of the Health Bureau is not to treat patients, but to prevent diseases! After all, the prevention and treatment of diseases is to cure the root cause, and the treatment of the sick is only a symptom.

Therefore, when he rectified the order of the entire Taoqiu, he attached great importance to the hygiene of the entire city! He asked those guilty rangers to clean the streets and alleys of Taoqiu every day and keep the entire city clean and tidy, not only for the sake of improving the city's appearance, but also to prevent serious infectious diseases such as plague and cholera from ravaging Taoqiu!

And one of his proudest things about the prevention and control of infectious diseases is undoubtedly the creation of the entire Taoqiu tap water system! Through this system, the Taoqiu people can drink clean drinking water from the upper reaches of Jishui and discharge the sewage generated by the entire city downstream, which can ensure the basic safety of drinking water.

However, if we talk about the measures that play the greatest role in the prevention and treatment of infectious diseases, it is really not these measures of Dai Yan, but the tradition of the entire Chinese civilization!

The biggest difference between the Chinese civilization and other civilizations in the world is that the people of the Chinese civilization like to drink hot water, while the people of other civilizations either drink cold water or dairy products, which are different from China. Such a tradition has basically existed since the Xia Dynasty, and it is such a tradition that has made the Chinese immune to most infectious diseases!

In the history of Europe, it was normal for a plague to wipe out more than a third of a country's population in a short period of time! Later, when the Age of Discovery came to the Europeans, they took a fancy to the rich land of the American continent, and the Indians, the original owners of the American continent, became their footsteps. So they brought this "fine tradition" to the Americas, and the Indians were exterminated by more than 90%! In fact, most of these people were not killed with knives and guns, but with biological weapons such as infectious diseases!

In the history of China, except for the collapse of order at the end of the dynasty, or when we encountered smallpox, a disease transmitted by droplets, it was basically impossible to have a plague and suffer heavy casualties!

After all, most of the time, the disease enters from the mouth, and there are indeed more germs living in the water. However, whether it is bacteria, fungi, or viruses, these microorganisms cannot be stored in boiling water for a long time! Because the most important structure in the body of living organisms is protein, boiling water can destroy the structure of protein, and these microorganisms will naturally not be able to survive.

After Dai Yan discovered tea and popularized it, it was even more powerful for the prevention and treatment of infectious diseases. Not to mention that boiling water itself can sterilize, there are also many beneficial ingredients in tea. Among them, the tea polyphenols themselves have antibacterial ability, the β-carotene in tea pigments has the function of sterilization and antibacterial, theanine can delay aging, and tea polysaccharides can improve immunity. The great effect of tea has ensured the health and safety of Taoqiu people.

For specific diseases, Dai Yan has created specific institutions and used specific methods to prevent them.

In today's Warring States Period, the more serious infectious diseases in the whole world mainly include typhoid fever (intestinal typhoid), miasma (malaria), corpse transmission (tuberculosis), boils (leprosy), etc., and the disease of smallpox (smallpox) is not a disease native to China, but was transmitted to China after Zhang Qian of the Han Dynasty passed through the Western Regions.

For typhoid fever, Dai Yan basically prevents and treats it by boiling water and drinking tea. As for malaria, Dai Yan ordered the Health Bureau in Taoqiu to publicize the importance of mosquito control and mosquito prevention to the common people of Taoqiu and even Fengyi, and basically nip the disease in the bud.

For the prevention and treatment of tuberculosis and leprosy, Dai Yan only learned a little from later generations that it can be prevented by vaccinating BCG. However, Dai Yan is not a professional doctor, and he does not know how to cultivate BCG, so he has no way to prevent and treat pulmonary cough and leprosy.

As for schistosomiasis, a disease that will be talked about in later generations, Dai Yan's move to seize gold and silver from the Japanese slave country can be said to have triggered a butterfly effect. Because there was no schistosomiasis in southern China in ancient times, this disease was only found in Japan! When the Japanese slave doctor Kong Tongjia brought back a small number of snails and gave them to Dai Yan as if showing off, Dai Yan immediately reprimanded him, burned all the snails with fire, and then sterilized them with tea seed cake and lime!

Since then, he has been guarding against the invasion of this disease! He issued the strictest order to prevent Japanese snails from entering the mainland through the ship, and if they were discovered, Tao Qiu would immediately revoke the ship's permission to go to sea and put the captain in prison!

Under such severe measures, the entire Taoqiu, as well as Fengyi and the East China Sea, could be regarded as not hearing the news of the large-scale schistosomiasis!

The Department of Health has been effective in the prevention and treatment of infectious diseases, and at least in the years since its establishment, there has never been a large-scale plague event in the whole of Taoqiu.

After fundamentally preventing and treating large-scale diseases and completing the control of the "original", Dai Yan needed to make some changes to the "standard".

In this era, doctors who treat diseases are actually no different from wizards. Especially in a superstitious country like the Song Kingdom, which worships witches and ghosts, it is extremely common to trust wizards and let wizards heal diseases. Although Dai Yan vigorously attacked the power of wizards when he was in Fengyi, he did not have a good way for wizards to occupy the profession of doctors.

After all, even in the era of scientific prosperity in later generations, the most technologically advanced hospitals cannot guarantee absolute safety for the diagnosis and treatment of patients. Dai Yan once heard doctors say in later generations: even the simplest appendicitis surgery can fail and lead to death! In today's Warring States era, those wizards first give you a sentence to treat the disease, just look at the will of heaven, saving a person is his merit, saving the dead is your life should be like this, for such a scoundrel, what can you do?

And before Dai Yan cultivates a truly powerful medical system, he can't really turn his face with these wizards! After all, although these wizards are scoundrels, they still have experience in healing!

Before establishing a strong medical system, we must first have abundant medicines, and in this regard, Dai Yan knows a lot!

When it comes to trauma, the most important thing is disinfection. And the best disinfection product, in addition to boiling water, is alcohol!

Winemaking, for Taoqiu, which now has a basic chemical system, is absolutely no problem! However, in general, whether it is from grain or other fruits, the wine produced is low-alcohol alcohol, and such wine cannot be used as sterilized medical alcohol. This necessitates increasing the concentration of alcohol.

The boiling point of alcohol is 78°C, which is much lower than the boiling point of water of 100°C. In this way, taking advantage of the difference in boiling point between these two substances, the alcohol can be separated by distillation!

The specific method is nothing more than putting the preliminarily fermented low-alcohol wine into the boiler for steaming, and controlling the temperature in the boiler so that it exceeds the boiling point of alcohol without reaching the boiling point of water. In this way, a large amount of alcohol will boil and evaporate, at which point it will be guided through a special catheter and the alcohol can be distilled.

Of course, the alcohol obtained by this crude distillation method is actually not particularly high. Because the alcohol obtained in this way, not to mention that there will be a large amount of water vapor overflowing, that is, the distilled alcohol, in fact, is not pure alcohol, but a constant boiling substance combined with water and alcohol. The alcohol content of distilled spirits obtained by crude distillation is actually only 40% to 50%.

Although 40 to 50 percent alcohol can also be used to prevent pressure sores and reduce fever and fever, it can also be drunk as a spirit. However, if you want to disinfect with alcohol, you must use alcohol with a concentration of 70 to 75 percent. In later generations, in order to obtain this solubility of alcohol, rectification was generally used.

However, distillation has much higher requirements for the strength and process of distillation equipment. The equipment used for rough distillation can be made of bamboo, and the boiler can even be replaced by wooden barrels. However, distillation requires the construction of a distillation tower, so that the alcohol can flow out of the top and bottom of the column through multiple partial liquefaction and vaporization in the equipment, and the temperature required for these two positions is extremely strict, far less than the requirements of crude distillation! And such sophisticated equipment, with the humble level of machinery industry in Taoqiu, is absolutely impossible to complete!

Therefore, Dai Yan chose another way to dehydrate, which is to use quicklime for dehydration! The main component of quicklime is calcium oxide, which can react with water to form non-volatile calcium hydroxide. In later generations, it was even possible to produce anhydrous alcohol with a purity of 99.5% by such a method!

In this way, Dai Yan can get all the alcohol of various concentrations.
