This night, it is unknown whether Xin Ziqi slept well, but Ji was busy until late to sleep.

The Xinzi period didn't really come later in the season, and it arrived early before the time came.

Ji saw that his face was not tired at all, and he didn't know if he had really rested or couldn't wait to try the medicine.

After all, getting excited when encountering incurable diseases or new drugs is also a common occupational problem for most doctors.

However, since he was online, there was no need to say anything, and the two went to the earthen house together.

Due to the long operation time, Ji couldn't be distracted and ran home again, so let Hu Dacheng accompany Dabao, the two of them didn't have to eat lunch, and she didn't want to bring Dabao here...... I still sent it to the Hu family and asked the widow to help take care of it.

Hu Liang was uncomfortable at home, and when he heard that he was going to treat the homeless man's injuries today, he also ran to join in the fun.

However, Ji didn't let him in this time, to be precise, unrelated people were blocked out of the door, including Hu Dacheng, who followed later.

After sending off Xinzi yesterday, I came to the earth house in the evening to deliver food to the homeless, and Ji sprinkled homemade disinfectant inside and out, and came over in the morning to sprinkle it again.

Even if the room cannot be completely purified, the total amount of microbial particles and particles in the air cannot be reduced to the permissible level, but it is always necessary to ensure that the operating environment is as clean and dust-free as possible, and at the same time ensure that it is ventilated.

Before entering, Ji Rang Xin Ziqi changed into a quirky smock that was below the knee and laced at the back, as well as a hat and mask of the same color.

But it doesn't matter, the point is, they're all white.

Ping An felt unlucky, but Xin Ziqi did not have any objections, and let the season be arranged.

Ji took the time to explain: "Doctors need a clean and safe environment, including themselves, which is good for you and patients......

She didn't plan to make it white, because in the eyes of the ancients, it was almost the same as wearing linen and wearing filial piety.

Not to mention whether the doctor himself will feel unlucky, the patient is just afraid that he will pout and curse on the spot, isn't it?

Moreover, when the operation is done, it will be more or less stained with blood, and the white surgical gown is too pigmented, and it is scary to say that it is not easy to clean after being stained with blood.

Another factor is that if the surgeon is faced with bright red blood for a long time, if he looks away during the process, he will often have an illusion due to the afterimage of the complementary color, which will lead to inability to concentrate and even affect the effect of the operation.

Green and blue are just the ones that avoid the interference of complementary afterimages, while also relieving the patient's stress and giving them a more comfortable feeling. And even if it is stained with blood, it will appear dark and not too obvious.

"I wanted to make it blue or green, but I couldn't find either of these fabrics at home...... You wash your hands with this. ”

Next to the wash basin is a clay pot containing a brown, viscous liquid that smells of medicinal herbs.

"The disinfectant I boiled. Don't think that you can clean your hands just by washing them with water, there are many bacteria on the human body that cannot be seen by the naked eye, and it is good to contact under normal circumstances, so you should pay special attention to the operation on the patient, otherwise no matter how good your operation is, it is likely to fall short because of a small bacterial infection......"

Xin Ziqi dug a little and put it in the palm of his hand, smelled the smell, and began to ponder again, but fortunately, he hadn't forgotten the business.

Ji saw that he was almost ready, so he planned to wait outside.

Although it is not very reassuring, but in ancient times, it is not as good as in modern times, and medical skills are mostly inherited by the relationship between master and apprentice father and son, and outsiders are not allowed to peek into their ways.

Especially the ancestral medical skills like the Xin family are not allowed to be passed on.

She was just about to turn around, but was stopped by Xin Ziqi reaching out.

"I'll be treated together."

Ji looked at him in surprise.

Xin Ziqi still has that bleak look.

"You are willing to tell me such a miraculous anesthetic prescription, what do I need to hide from you. And I don't think you'll be interested in this little bit of skill from the Xin family. ”

Ji smiled: "I agree with your words, except for the last sentence." Please, Dr. Xin. ”

Xin Ziqi finally showed a faint smile on his face.

Ji changed into the coat, hat and mask that he had prepared for his assistant Ping'an, washed his hands and disinfected his hands, and entered the hall with Xin Ziqi, and the door of the hall was closed.

Although the kang was facing the window, as soon as the door was closed, the light was still a little dim, but fortunately, Ji had already prepared and asked Hu Liang to send a wooden bed over to serve as a temporary operating table.

The plank bed was pressed against the wall by the window, on which the homeless man was lying at the moment, his eyes fixed on the beams, and he blinked for a long time, wondering if he was nervous.

Ji Gu couldn't ponder his thoughts, she was studying the rudimentary version of the operating box in the Xin Zi period.

In her life, the unearthed cultural relics of the Tang Dynasty already had common surgical instruments such as tweezers and scissors.

During the Song Dynasty, a complete set of commonly used surgical instruments, such as needles, scissors, knives, forceps, chisels, etc., appeared, which were recorded in books such as "The World Medical Prescription" and "Yongzhi Xuanfang".

Among the medical devices unearthed in the Ming Dynasty, in addition to iron and copper scissors and tweezers, there is also a willow leaf knife with a sharp edge at one end, which is very similar to modern scalpels.

The scalpel commonly used in the Xinzi period is this willow leaf type.

Others, such as scissors, tweezers, hooks, triangular needles, flat-edged knives, and moon-bladed knives, are also quite a lot.

Although the style looks a little rustic, it is much better than expected.

Ji Da breathed a sigh of relief.

Unexpectedly, there are bigger surprises waiting for her later.

Xin Ziqi took out a boxwood box from the bottom of the operating box, as if he was holding some rare treasure. Inside, it's a pale blue, translucent line.

"This is ......" Ji had actually guessed it, she just couldn't believe it.

Xin Ziqi thought she didn't know her, and explained: "There are several cities in the south near the sea, and there are often countries to buy and sell. It is said that if you use this thread to close the wound, you don't have to remove it after healing, and it will melt with the flesh and skin over time. I spent a lot of money, but I just bought so much. ”

Ji picked up a piece and put it in the palm of his hand, looked at it, sniffed it again, and basically could already be determined.

Although I don't know how it was made at the level of craftsmanship of this era, there is no doubt that this is absorbable suture, and the raw material should be something like sheep intestines.

It was not easy to come by, carefully treasured, and I have been reluctant to use it, but now I took it out to treat a homeless man.

Xin Ziqi's thoughts, Ji can probably guess some.

The shock caused by the anesthetic was too great, and he wanted everything to be used for the best, it didn't matter who the patient was, he just wanted to do the miracle better.

It's a pity......

"It's a rare suture material, but it's not suitable for the situation, at least, not on homeless people."
