Chen Qi wanted to laugh when he saw everyone's dejected look:

"Yes, it is hemodialysis, but hemodialysis is not enough artificial kidney technology, but also needs to add an artificial liver technology, the focus of treatment is not only to remove arsenic toxins from the patient's body and blood, but also to let the patient have liver cells to grow back until they can recover their function."

Artificial liver + artificial kidney?

To doctors in the eighties, this sounded like a fantasy.

Hemodialysis is understood as an artificial kidney, so what the hell is a worker's liver? How does it work? How to replace the law? Don't say you've seen it, you've never heard of it.

But it is a big problem for others, but it is a very simple matter for Chen Qi.

Because whether it is a continuous renal replacement therapy dialysis machine (CRRT) or an artificial liver support system (ALSS), both of these machines are available in his space hospital.

This kind of thing that looks like black technology in the 80s is a routine equipment in major hospitals in 2022, and the operation is also very simple and the degree of automation is very high.

But how to take out these machines and use them is a headache for Chen Qi.

After all, these machines are all cross-era, not to mention that there is no domestic, not even abroad, so a big machine can't hide it if you want to, how to explain that this thing appeared suddenly?

In case someone is poked out, it is another right and wrong, especially under the premise that some teams want to control everything, and any accidents are not allowed by them.

It wasn't until he got off work in the afternoon that Chen Qi thought of a way to get the best of both worlds.

"Who's on the shift tonight?"

Wu Guoliang, a small surgeon, and Yang Caisheng, a young doctor in internal medicine, raised their hands weakly: "Dean, we are on duty tonight." ”

Chen Qi smiled and shook his hand:

"Let's go, let's go, count your luck, you don't have to be on duty tonight, there are two people on the night shift with me and Dr. Lan, in addition, I will tell everyone that the night shift for the next week will be on me and Dr. Lan, and the nursing class, Chen Li and Yang Xiuxiu will work hard and accompany us on the night shift for a week."

Wu Guoliang and Yang Caisheng couldn't believe their ears, because only the little doctor was on duty for the leader on the night shift, but they had never heard of the dean and the head of the department on duty for the little doctor.

Is this the dean's temptation? You can't ignore lifting.

"Dean, we, we're on duty."

Chen Qi said sincerely: "It's okay, you usually work hard, this time let me and Dr. Lan go up for a week, and then you will go up." ”

The two little doctors wanted to say something, but they were suddenly gently pulled by the head nurse Liu, signaling them to listen to the dean.

As for Chen Li and Yang Xiuxiu, of course they have no opinion, the dean named them to work the night shift, which is not to punish them, but to represent the dean's trust in them.

Because often when the African team comes on the field, Dean Chen has some technology or equipment that he doesn't want others to know.

This kind of trust can only be enjoyed by the henchmen of the henchmen.

Lan Lijuan is such a smart woman, as soon as she heard her husband's arrangement, she knew that he would definitely make some trouble in the middle of the night, so she also nodded:

"Then I'll go back first and settle the two little ones before I come to work."

Chen Qi looked at his watch: "Don't worry, you can come over after 9 o'clock in the evening, I'll take it first." ”

The dean said that it was arranged, and the other doctors, whether they were curious or indifferent, all obediently left work, and the dean's secret was not something that outsiders could know casually.

When everyone left, they could still see Dean Chen thinking about several monitors.

At 8 o'clock in the evening, Lan Lijuan came over early with a few thermos buckets:

"Chen Qi, come, this is the pork rib soup that the eldest sister stewed for you, you eat something first, are we going to struggle all night tonight and don't have to sleep?"

As soon as Chen Qi picked up the spoon, he fell onto the table, his face full of horror:

"Wife, don't scare me, we're all three people, and I can't bear my old waist after one night."

"Phew, what are you thinking?" Lan Lijuan's face turned red.

Chen Qi smiled, picked up the spoon and continued to drink the soup, while Lan Lijuan read the day's illness record and examination report again.

waited until midnight, when the night shift and the night shift of the hospital were handed over, and the whole hospital was quiet, Chen Qi stood up at this time, and then sneaked out of the ward.

After a while, the inexplicable Lan Lijuan, Yang Xiuxiu, and Chen Li saw Chen Qi pushing a machine over, and the machine was tightly wrapped in cloth.

"Don't just look at it, push this machine in, Chen Li, you go to the door and keep guard, and it is forbidden for idle people to enter and exit tonight."

Lan Lijuan and Yang Xiuxiu had just taken over the mysterious machine, and Chen Qi went back outside, and after a while, he pushed another machine tightly wrapped in cloth.

Waiting for the two machines to be pushed into Fu Zhenzhen's ward, Chen Qi also took a newspaper to keep the glass on the door tight.

Chen Li was guarding at the entrance of the inpatient department, and Yang Xiuxiu was guarding at the door of the ward, which was considered a double insurance, and there were only two people left in the ward, Chen Qi and Lan Lijuan, and Fu Zhenzhen who was in a coma.

Lan Lijuan was confused: "Chen Qi, what are these two machines?" ”

Chen Qi peeled off the two pieces of cloth in one fell swoop, revealing two machines that Lan Lijuan had never seen before, which looked very complex in structure.

"Lijuan, keep it secret, I smuggled these two machines from abroad, and they are still in the laboratory research and development stage, so they can't be seen by outsiders, and it will be a big trouble if they leak secrets."

Lan Lijuan nodded, Chen Qi has always been elusive, and she is not surprised that she can get any kind of machine and medicine.

"Look, this machine is artificial liver, the full name is artificial liver blood purification technology. The function, just listen to the name, is to temporarily replace the damaged liver to perform various functions. This includes removing jaundice and toxins from the liver and replenishing clotting factors and proteins that need to be synthesized by the liver itself. ”

Lan Lijuan's heartbeat was already beating excitedly at this time.

Because she feels that she has been exposed to the world's top medical equipment, a device that can replace the liver, it is extraordinary to think about it.

"Chen Qi, what is the principle of this machine's operation?"

"This thing is simple and simple, but difficult to say, let's describe it this way, artificial liver blood purification technology refers to plasma exchange and blood adsorption technology, which means that inflammatory substances or toxins dissolved in the blood are adsorbed to solid substances with rich surface area.

Inflammatory substances and toxins are then removed from the blood, so the artificial liver technology is specifically designed for blood detoxification. It uses exchange transfusion to remove toxins from the patient's plasma, and replaces the patient's plasma containing toxins with healthy plasma, replacing about 50% of the plasma in the body each time.

If you look at this complete set of equipment, it actually includes the principles of plasma exchange, hemodialysis, hemofiltration, blood plasma perfusion, molecular adsorption circulatory system, continuous blood purification treatment, etc., which is very, very complex. ”

In fact, Lan Lijuan can only understand half of it, and this Chen Qi also knows.

Chen Qi also removed a dialyzer, which was a long cylindrical type, and when it was opened, it was all white filaments, like the dust whisks used by Taoist priests.

"Wife, you see, this white fiber, in fact, is hollow, the principle of dialysis is in this, just like pickled eggs, you think, we put salt around the eggs, after a while the eggs will be salty, right?

This shows that the molecule of salt can cross the shell of the egg into the egg, and we should remove the toxins in the blood according to this principle, which is the principle of diffusion. When we draw the blood, it goes out of the hollow fibers.

Then the dialysate goes from the outside, and the wall of the hollow fiber is like an eggshell, with holes, and then the toxins in the blood enter the dialysate outside the hollow fibers through this hole, and finally the dialysate washes the toxins away. ”

Lan Lijuan still doesn't seem to understand, and the general principle is known, but how to do it, she knows that this is a very complex project.

Chen Qi introduced himself excitedly.

"Wife, you see, this is the blood pump, this is the APF continuous blood filter, this is the albumin pump, this is the bilirubin adsorber, this is the activated carbon, and here, this is the place where the dialysate is loaded, and this is the place where the wastewater is discharged.

Taken together, this series of devices is equivalent to a cycle, which can remove protein binding and water-soluble toxins from the blood, and so on.

It is equivalent to this machine is the liver, which removes a large number of toxic substances from the body of patients with liver failure, and can replace the detoxification and metabolism of the damaged liver.

At the same time, it can also allow her liver to rest, and then let the liver cells slowly repair themselves.

After Lan Lijuan was excited, she also heard another question:

"Chen Qi, according to what you said, the artificial liver can completely replace the artificial kidney, because the whole set of equipment for the artificial liver includes hemodialysis."

Chen Qi thought for a moment and said:

"The basic principle is similar, but you think, the main function of the liver is detoxification, and the main function of the kidney is detoxification, there is still a difference, and the artificial lung cannot be used for a long time, there are still certain side effects."

Lan Lijuan is an internist, and her mind is a little more delicate, so she asked:

"Now there are artificial livers and kidneys, so are there artificial lungs and artificial hearts?"

"Yes," Chen Qi replied without hesitation.

"Artificial lungs can also be called Extracorporeal Membrane Oxygenation, referred to as ECMO, this thing is amazing, it can completely replace the heart and lungs, theoretically as long as you have money, keep using Extracorporeal Membrane Oxygenation, you will never die."

But expensive is really expensive, as soon as the Ye Ke film is opened, the start-up fee of this machine alone is 50,000.

Subsequently, the minimum consumption per day is 20,000, the median is generally about 60,000, and the most expensive 100,000 a day is also a small meaning.

Marking the key points, to be examined, this is the cost of one day.

If your grandfather hadn't climbed a snowy mountain, or your father didn't have a coal mine, ordinary people wouldn't have been able to afford it.

There used to be a mayor in Wanwan Province, who was an intensive care medicine doctor by profession, and he was a well-known "Yek membrane expert".

Later, major hospitals in China also introduced a large number of Ye Ke membranes, but there are too few doctors who can use them, and they are considered the top high-end equipment in medical devices.

After listening to Chen Qi's words, Lan Lijuan didn't speak for a long time, just looked at the two machines in front of her like a distracted look.

Chen Qi has a rough line and has been fiddling with these two machines, and some dialysate and heparin need to be installed manually, so he didn't notice his wife's abnormality.

It was only after a long time that Lan Lijuan came to a leisurely sentence:

"Chen Qi, do you say that the gap between medical care and technology between China and foreign countries is really so big?"

Chen Qi held the injection in his hand, and he didn't know how to answer for a while, and he finally found out that his wife was in a lost mood at this time, as well as the self-doubt in his heart.

"This, how to say this, if only from the point of view of medical equipment, our country is actually a lot behind, this backwardness is all-round, and not only backward now, in the foreseeable next 40 years, will continue to lag behind.

However, in terms of medical technology, our country is not comprehensively backward, for example, Professor Wu Mengchao's hepatobiliary surgery is absolutely world-class. Another example is the Helicobacter pylori project that you are engaged in, which is also world-class.

In addition, if you look at my endoscopic level, is it also world-class? Those foreigners have to go to Viethorn to see a doctor, so we Chinese people are not stupid. On the contrary, the Chinese are too smart, too smart.

For example, the research and development of this dialysis machine may require an investment of hundreds of millions, or even billions or tens of billions, and some people will think that since I can buy it for hundreds of thousands or millions, why invest hundreds of millions of dollars in research and development? This money is good for eating and drinking, and it can also be put into personal pockets.

For another example, later we were able to build a domestic hemodialysis instrument, what localization rate of 80% desperately bragged, but in addition to the outer shell is made by ourselves, all the core equipment inside is imported. ”

(As of 2022, hemodialysis equipment and consumables mainly include dialysis machines, dialyzers, flow irrigation devices, hemodialysis pipelines, hemodialysis powder, etc., 90% of which are imported.) ）

Chen Qi is a reborn person, and his memories of being more than 30 years ahead of this era naturally can be seen more thoroughly and clearly.

The two husbands and wives sat on chairs together, worrying together, and Chen Qi once again raised his middle finger to those "foreign compradors" who advocated trade, industry and technology.

These traitors, who lurked in the country and had a certain right to speak, finally made our country be choked by foreign countries at a critical moment and became quite passive.

At this time, the monitor suddenly sounded "doodoo", which woke the couple from deep thought.

Chen Qi slapped his head: "Damn, I almost forgot my business when I was worried about the country and the people, come to my wife, today I will teach you how to operate artificial liver and artificial kidney for my husband, let's fight for one night!" ”
