The medical concubine never thinks of going out of the wall

Chapter 515 Normal Saline
There are a lot of skilled craftsmen in the palace, Tang Nineteen is not worried that they will not be able to make a needle, but worried that it will be too thick to be used, so Xu Jing is asked to go around, iron and copper are difficult to make for a while, and the craftsmanship is complicated , it doesn't matter, jade is good, no matter how bad it is, wood is also good, it has been sterilized at high temperature, and it can be used once.

On Tang Nineteen's side, there is also a lot of work to do.

Distilled water, she needs distilled water.

Without a distillation device, some local methods can only be used.

Someone took an iron pot, put an appropriate amount of water in the pot, put a steamer drawer on the pot, and asked her to cut off one of the two layers of steamer drawers, so that she had the depth she wanted.

In the middle of the steamer on the lower floor, she put a ceramic bowl and looked for it everywhere, but there was no suitable lid. She simply asked someone to smash the water tank, and smashed a large piece of smooth arc-shaped pottery. Face down, covered in the steamer.

Start a strong fire, heat it until the water is half boiled, pull out the firewood, and switch to a small fire.

From time to time, she looked in through the gap between the porcelain steel and the steamer.

Along the curved surface of the tile, there are drops of water, which is pure distilled water.

Several pots start working at the same time.

After the first distilled water came out, she put it into a pot and steamed the second distilled water.

Due to limited conditions, we can only try our best to be meticulous and sterile.

The second course of distilled water received two porcelain bowls.

She asked people to go to the Tai Hospital, and took the scorpion (deng 3 sounds), and she was familiar with the concentration of normal saline.

[-] percent sodium chloride solution.

Weigh the proportioned salt with a chopstick, transfer it into distilled water, stir well with clean boiled and sterilized chopsticks, and put it into a pottery pot that has been boiled at the same high temperature.

They also asked people to find a few pieces of clean sheepskin. After being sterilized under high temperature and water, they were piled up layer by layer, wrapped on the long pottery cup, tied several times with rope, tied tightly, turned upside down, and no water leaked.

This bottle of salt water is really time-consuming and laborious to make, but it is quite a sense of accomplishment.

It's just that Xu Jing went and went, but never returned.

Tang Nineteen went in to check on the situation of the Empress Dowager, but she hadn't woken up yet, and the porridge was hot, but she couldn't feed it.

The empress dowager who was sleeping had her brows tightly wrinkled, her expression was painful, her face was old, and it was really distressing to see.

After staying with the queen mother by the window for more than half an hour, Xu Jing finally came back, holding a box in her hand, inside the box were "needles" of several materials.

"Sixth Princess, let's see which one works."

Tang Nineteen walked to the bright place of the window and took a closer look. Sure enough, it was the imperial palace. Her request was so outrageous that even the iron ones were built for her in such a short period of time.

It's just too thick. After all, the craftsmanship is complicated. It's not bad to be able to make it like this in a while.

She didn't explain clearly about the iron ones and the wooden ones, and didn't remove the burrs for her. In the end, although the jade was a bit thicker, it was barely passable.

It's really extravagant. If she read correctly, she used high-quality white jade. Tang Nineteen has never used jade needles in his life, and was pushed by others.

However, jade is too brittle, and it will test her skill even more, so she doesn't like to use it.

With the needle, the rest will take some effort, but fortunately, she has a composition in mind.

After a lot of work, he used jade as a needle and thin bamboo as a catheter to sew a piece of sheepskin as the titration controller in the middle, and connected the catheter and needle with sheepskin, and used the pottery cup wrapped in sheepskin as a medicine bottle.

Everything looked a little funny and crude, and she was afraid that she might fail, so she experimented on the back of her hand first.
