Reborn in the 70s as a military doctor and meets a special soldier

But theoretically, her friend probably couldn't get the protective suit back.

She remembered that protective clothing only appeared in China more than ten years later.

The international environment is not good at this time, and of course, the main target is them.

The great powers are all deliberately squeezing them out and blockading them. It is not easy to get advanced things from developed countries for development.

Lin Xia must have suffered a lot, but that is all in the past!

Although Lin Xia didn't know the material of the protective clothing, Song Wei did!

In later generations, scientists will not even be needed to do this. Protective clothing, medical gloves, medical masks, etc. are all produced by mature medical device companies.

Song Wei has specialized knowledge in this area and has also visited these medical device factories.

Of course, Song Wei also knows how to be a good person. She did not give a direct answer, but spoke in a guided manner.

"Although I am not a scientific research expert, as a medical worker, I can still share some of my work status, and perhaps give Expert Lin some direction and thinking."

"Just call me Lin Xia. Just tell me, I'm welcome!"

Song Wei smiled and nodded: "Let me share with you our work flow first.

Our work area is divided into consultation and general ward area, surgical area, intensive care area and infectious disease area. Different areas accommodate patients with different levels. Generally speaking, the condition becomes more serious as time goes by, and the dressing requirements are also different. different. "

"Hmm, so actually the concept of medical protective clothing is still general. Different protection categories still have to be provided according to different areas, right?"

Song Wei nodded with a cowardly expression on her face.

In modern times, the medical protective clothing they commonly use is divided into four categories. The first type is daily work clothes, which are white coats. White coats are completely sufficient in general wards and consultation areas.

The second type is surgical protective clothing. As the name suggests, it is mainly worn during surgery.

The third type is isolation gown, which is generally used by medical staff and family members when patients are admitted to the critical area or sterile area.

The fourth type is protective clothing, which has the highest level of protection and is also the most difficult to wear. It is generally used in infectious disease areas.

However, according to the current level of technology, it is obviously not possible to produce particularly powerful protective clothing.

This involves its production materials. For example, protective clothing generally uses SMS composite nonwoven fabrics, flash evaporation nonwoven fabrics, etc. These processes are not yet available at this time.

The only thing that can do this is probably high-density fabrics.

"In fact, Expert Lin can refer to the manufacturing method of raincoats. After all, for us, protective clothing mainly has three barrier functions, one is liquid barrier, the other is microbial barrier, and the third is granular material barrier."

Originally, Lin Xia thought she was quite professional, but when she heard Song Wei's speech, she suddenly became confused.

What is all this and what? This world is indeed a place where there are people outside the world and there is a world outside the world, and academic masters are among the people!

Lin Xia smiled sheepishly: "Dr. Song, can you explain it in detail?"

Song Wei was not stingy and continued to speak.

"I personally think it is best for protective clothing to have a certain degree of waterproofing. After all, we will come into contact with the patient's blood, body fluids, other secretions, alcohol, drugs, etc. during surgery. Protective clothing can act as a liquid barrier. This allows doctors to avoid being infected by viruses carried by patient fluids during surgery.

As for microorganisms, they mainly refer to the bacteria and viruses you just mentioned, Expert Lin. After all, we will be in contact with the patient's wound during surgery. Protective clothing can largely avoid contact with the patient's wound during surgery and avoid cross-infection between doctors and patients.

Particulate matter is actually similar. It actually prevents airborne viruses from attaching to the skin in the form of aerosols and being absorbed by the body. "

"That's it!" Lin Xia quickly recorded the things Song Wei mentioned as if she had found a treasure.

At this time, her downed brain was also running wildly, thinking about what kind of material could block what Song Wei said.

She couldn't help but murmur to herself: "Currently, the majority of our weaving industry is traditional machine weaving, but these fabrics are what we wear every day. There is no problem in making white coats, but obviously not in making protective clothing.

I heard that there are some high-density fabrics in the Jiangnan area, but because of the high-density weaving, the output is very low, and the supply exceeds demand. I have ordered the goods for a long time, but I haven't gotten them yet. "

Song Wei's eyes lit up. One of the materials used to make protective clothing is high-density fabric!

Strictly speaking, there are two major categories of materials for protective clothing, one is woven and the other is non-woven.

Non-woven fabrics are the disposable protective clothing of later generations. As mentioned just now, the current industrial level of these processes cannot meet the production conditions, so we can only make a fuss about woven fabrics.

There are other methods in woven fabrics. Without going into details, high-density woven fabrics are indeed sufficient for surgical operations.

Of course, it doesn’t mean it can be used directly, it still needs to be further processed.

"Expert Lin, can I ask what chemicals are waterproof?"

"There are many, such as fluorocarbons, silicones, benzene compounds, etc., which all have waterproof properties."

Song Wei was ecstatic in her heart, but her face remained calm.

"I see. I have a bold idea. If I add these waterproof materials to the high-density fabric, will it be as waterproof as a raincoat?"

Lin Xia's eyes lit up when he heard this: "Your idea is very good! Yes, I can study the waterproofing agent first, and then try to use the waterproofing agent when the fabric comes back. Maybe I can really make an excellent piece of liquid-proof material. Where’s the fabric?”

Song Wei was ecstatic, she was indeed a smart girl! She has completely mastered the art of making protective clothing!

As long as Gaomi Zhibu comes back, this experiment will basically be successful!

To be honest, it was an unexpected surprise to get this result. Originally, she just wanted to get in touch first to see if she could make a model of protective gloves. She never thought that Comrade Lin Xia was so far-sighted that she was already secretly planning it. About medical protective clothing.

It's almost as if someone will hand you a pillow whenever you feel sleepy. This trip is really worth it.

Lin Xia also had the same idea as Song Wei. God knows that in the past few years since she returned to China, her work has been stagnant, and she herself is dying of anxiety.

She never expected to meet Zhao Wanfeng first. Because her husband is a military research expert, she gave herself some ideas for military protective vests, which was already very lucky for her.

Unexpectedly, I met Song Wei again today.

This Dr. Song is even more powerful. Not only does she know a lot about bullet-proof clothing, she even has a lot of research on medical protective clothing. Mom doesn’t know who she is.
