Liu Min finally decided to put the operating room in the prison officer's court.

As the name suggests, the prison officer's court is a place where prisoners are interrogated, but the space has four or five rooms, and the house is 1,200 square meters larger; It is ideal for use as a temporary operating room.

Liu Min, together with Hongyun, Green Apricot, Lanmei, and Bai Xue, thoroughly sterilized and disinfected the space of 1,200 meters.

All four windows on the two walls were hung with curtains, and a pair of shadowless lamps hung from the top of the wooden bed, which served as an operating table.

In the second year of Qianheng of Taizong of the Northern Song Dynasty (980 AD), Liu Min used a shadowless lamp in the temporary operating room of the Qingshichuan Horse Farm; No matter from that point of view, there is no one before or since.

What is even more surprising is that it is a generator that supplies power to the shadowless lamp.

Do you believe such a thing? I don't believe it's your business, but Liu Min, a medical doctor in the 21st century, saved 6 injured people who were on the verge of dying because of fighting in such an environment.

There is no doubt that the shadowless lamp and generator were transmitted to Liu Min by Zhao Guanghui through the Mozi satellite and quantum technology; If you doubt it, then you should study quantum entanglement.

When Liu Min used shadowless lamps, generators, miscellaneous disinfectants, narcotic drugs, medical equipment, surgical knives, pliers, scissors, hooks...... One by one, after being supported, Liang Ding, Hongyun, Green Apricot, Blue Plum, and Bai Xue were stunned.

Chen Yiyun, Tu Youmei, and Lai Zhenyue, who had buried the three dead soldiers and returned, also looked sullen after seeing these things.

Chen Yiyun couldn't hold back and shouted: "General's sister - Liu Min has always been wearing general's clothes, Chen Yiyun calls her general's sister - what are you getting here!" The villain has never seen ......"

Chen Yiyun has never seen it, and it is naturally impossible for people living in the Song Dynasty to see it.

The "dong dong" vibrating generator can send out electricity, which is as strange as Chen Yiyu, who lived in the Song Dynasty, like Grandma Liu entering the Grand View Garden.

What's even more strange is that as soon as the generator goes off, the milky white guy hanging on the roof lights up; It's like a moon on the fifteenth night.

The milky white moon was said by Liu Min to be a shadowless lamp, why did he hang a shadowless lamp on the top? The reason seems simple, for the success and precision of the operation.

Later generations have long known that shadows are formed by light shining on objects, and shadows are different everywhere on the earth; The Arctic Circle is the "kingdom of adults" of shadows, because the sun there shines obliquely, and the shadows stretch far across the vast snowfields; The equatorial zone is the "Lilliputian country" of shadows, where the sun hangs high in the sky and the shadows become smaller.

If you look closely at the shadows under the electric light, you will also notice that the shadows are particularly dark in the middle and slightly lighter around them. The particularly dark part of the middle of the shadow is called the umbra, and it is slightly lighter on all sides. The particularly dark part of the shadow in the middle is called the umbra, and the gray part around it is called the penumbra. The occurrence of these phenomena is closely related to the linear propagation of light.

If you place a cylindrical tea tube on the table and light a candle next to it, the tea tube will cast a clear shadow. If two candles are lit next to the tea tube, two shadows will be formed that overlap but do not coincide. The part where the two shadows overlap is completely black, and this is the umbra; The place where there is only one candle next to the umbra is the half-light and half-dark penumbra.

If you light three or even four candles, the umbra will gradually shrink and the penumbra will appear in many layers. The same is true for objects that can produce shadows composed of umbra and penumbra under electric light.

The lamp is made up of a curved filament that emits light, not just one point. Light from one point obscures the object, and light from other points is not necessarily blocked. Obviously, the larger the area of the luminous object, the smaller the umbra. If we light a circle of candles around the above-mentioned tea tube, the umbra disappears completely, and the penumbra is too faint to be seen. According to the above principle, scientists have made a shadowless lamp for surgery. It arranges the lamps with great luminous intensity into a circle on the lamp panel to form a large area of light source. In this way, the light can be irradiated to the operating table from different angles, which not only ensures that the surgical field of vision has sufficient brightness, but also does not produce obvious umbra, so it is named shadowless lamp.

The principle of the shadowless lamp Liu Min would not understand even if Liu Min told Hongyun and Chen Yiyu to them; Because they had not been exposed to electricity, Liu Min only said that the shadowless lamp was borrowed from the witch god.

As for who the witch god is, where do they dare to ask, Liu Min is what he says.

Liu Min said that the instruments and medicines transmitted from the later generations with Mozi satellites and quantum technology were given by the witch gods, but the four girls who were about to be his assistants, Hongyun, Luxing, Lanmei, and Bai Xue, did simple training in surgical knowledge.

When Liu Min performed craniotomy and jaw bone surgery on Grandpa Fire and Fire Buffalo in the oak forest, he could only fight alone due to environmental restrictions; After two surgeries, she was so tired that she could barely get up from her stomach.

But at that time, his soul was attached to the village girl Liu Min, who was only seven years old and energetic; Take a short break and recover.

Now it is in the Qingshichuan Horse Farm, there are ready-made manpower - Hongyun, Green Apricot, Blue Plum, and Baixue Four Fangji, Liu Min made a simple division of labor for the four girls.

Hongyun is a roving nurse, Lu Xing is an instrument nurse, Lanmei is a dressing nurse, and Bai Xue is a handwashing nurse.

After the division of labor, Liu Min asked the four girls to prepare all supplies before the operation, disinfect the surgical instruments with soaking solution, wear isolation gowns and shoe covers during the operation, and not leave the operating room without special emergencies.

During the operation, it is necessary to strengthen the awareness of self-prevention, such as gloves should be replaced immediately if they are damaged; Needles, knives, and other sharp instruments should be placed properly to avoid injury.

When leaving the operating room, wash your hands with 0.2% peracetic acid for 1~2 minutes - these drugs used for disinfection are transmitted by Zhao Guanghui using quantum technology.

Liu Min also asked Hongyun and the four to rewrap the uncontaminated dressings and instruments in the operating room, and autoclave them for later use.

After the operation, all contaminated items should be disposed of separately and should not be taken out of the operating room without treatment; For the instruments, suction tubes, syringes, and cloths that have been stained with blood after surgery, soak them in 0.5% peracetic acid for half an hour and then take them out.

The instruments are cleaned and dried before autoclaving; The cloth is squeezed dry and packed and sent out; The syringe is cleaned and discharged; After the suction tube is cleaned, boil for another 15 minutes, wipe it dry and set aside.

The dirt bucket and suction bottle should be soaked in a solution of 0.5% concentration of 20% peracetic acid for half an hour, and then the sewage should be poured into the sewage pool, and the suction bottle should be soaked in 0.5% peracetic acid solution for half an hour after scrubbing.

The floor of the operating room, the operating table, the infusion stand, etc. are mopped with 0.5% peracetic acid, and the operating room is fumigated with peracetic acid or formalin; Ventilation after 6~8 hours of sealing.

Liu Min completely conducted simple training for the four Hongyun people in accordance with the requirements of the regular operating room in later generations.

Hongyun, Green Apricot, Blue Plum, and Bai Xue were a little interested at first, but then they felt that Liu Min was too verbose, and they laughed absentmindedly......
