"I'll tell you a story." Zhou Congwen was in a very good mood today and talked more.

Complete the system tasks, the equipment brought by the boss of the World Surgery Competition is very handy, and no matter which one is, it can make people happy.

Yuan Qingyao held a pen in his hand and gently tapped the medical record book, looking at Zhou Congwen's eyes carefully.

What Zhou Congwen wants to talk about is clinical experience, and it is definitely clinical experience. Yuan Qingyao's ears almost stood up and turned into antennas like Shen Lang.

"Once... during my internship, I took the patient to do cardiac MRI."

Because Liu Xiaobie always asks the bottom line, Zhou Congwen was also a little cautious when talking about clinical cases.

If he was so cautious, Yuan Qingyao would have asked the truth, and Zhou Congwen would definitely break up with him.

"I am very familiar with the patient, and I am an old patient, so I followed him into the computer room and helped the patient onto the bed."

"At this time, I suddenly felt something was wrong." Zhou Congwen said very seriously, "A sense of crisis arose from the bottom of my heart. I immediately looked back and saw the family of the next patient pushing a flat cart in and preparing to line up."

"..." Yuan Qingyao was stunned.

The nuclear magnetic chamber, flat car, metal objects... these words exudes a sense of danger.

Yuan Qingyao knew very well that if the flat car entered the magnetic range, he would definitely run straight to Zhou Congwen like a car.

Although I don’t know the model of the nuclear magnetic machine, no one knows what will happen if the force of at least 500 kilograms hits the body.

To put it mildly, it is a contusion, but the more important thing is a fracture.

Yes, the fracture is only slightly heavier, and the more serious it is kidney contusion, so nephrectomy is necessary, and even paralysis is not unexpected.

No wonder Zhou Congwen just said that this was the most dangerous experience.

"Later, Brother Zhou!" Yuan Qingyao brought himself in. I guess he would be stunned if he was in the magnetic room and didn't know what to do.

"At that time, the flat car had entered the extremely dangerous area. If you push the flat car half a meter forward, you will fly over." Zhou Congwen said seriously, "I turned around and kicked all the patients on the flat car."

“…”

It is hard for Yuan Qingyao to imagine this violent scene.

Moreover, Zhou Congwen's kick was too strong. Although he was still a certain distance away from the host and the patient's family had just come in, Yuan Qingyao was still convinced by this reaction and strength.

"I was really angry at that time. After I went out, I had a big fight with the family members who sent the patient, and I was also complained. This was the only experience I had quarreled with the patient and the family members of the patient." Zhou Congwen said.

"What are they complaining about you?" Yuan Qingyao was surprised.

The right and wrong of the matter is obvious. Once the flat car is "sucked" by the nuclear magnetic host, Zhou Congwen will definitely be squeezed in it, and the patients will definitely not be able to get it.

It can be said that Zhou Congwen saved his and the patient's lives with one kick.

But all this is complained about?!

"Haha." Zhou Congwen smiled, not explaining why he was complained for something strange, but continued, "There are nuclear magnetic vehicles in the United States and Canada, Europe, you have seen them."

“See.”

"There is a case report about a nurse operating illegally and was sucked into a nuclear magnetic machine. Do you know what to do when encountering this situation?"

"Shut down." Valley

"No." Zhou Congwen smiled, "Do you think it's a power outage?"

Yuan Qingyao nodded.

"That's because you don't understand the principles of nuclear magnetic machines." Zhou Congwen said, "Have you taken medical instrument courses?"

Yuan Qingyao shook his head, he was full of curiosity.

"Emergency demagnetization has a great damage to the machine and it also releases a lot of liquid helium... Forget it, let's talk about it again."

"Medical superconducting magnetic resonance, magnetization is simply to slowly increase the current in the main magnet coil to increase the magnetic field generated by the magnet, and after reaching the rated field strength, the coil is closed and the power is turned off.

The main magnet coil forms a closed loop, and the current will not attenuate in the superconducting state, thereby obtaining a stable main magnetic field."

"The term for magnetization is called excitation. Excitation is a machine that provides stator power to the generator or synchronous motor stator and provides magnetic fields for generators. To be simple, it is called magnetic charging, but you have to know that it will prevent others from thinking that I don't know when they say it out later."

Yuan Qingyao smiled bitterly, and Zhou Congwen was simply obsessive-compulsive disorder.

Such small matters need to be explained in a special way.

"Under normal circumstances, a magnetic resonance imaging device will not demagnetize again after the installation and commissioning is completed, unless there is a major emergency, and the fault causes overdue or removal.

Magnetic resonance equipment has emergency demagnetization switches, which are used in emergency situations, such as when things are sucked in and cut into pieces and cannot be removed. Demagnetization will release liquid helium, and it will be refilled the next time it is charged."

"Do you know how much liquid helium costs? Tons of it."

"..." Yuan Qingyao shook his head.

"If it is a smaller thing, it can be removed directly or with the help of a non-magnetic tool; if it is a larger one, it may be possible for many people to remove it, such as a wheelchair or a flat car.

If you really can't take it down, you need to demagnetize and release liquid helium."

"The nuclear magnetic field of our Second Hospital is 1.0, and demagnetization requires at least 1,500 liters of liquid helium. If it is 1.5, at least 2,000 liters of liquid helium."

"According to the current market price, it should be around 30,000 US dollars. If you convert it into RMB, do you know how expensive it is."

"Uh..." Yuan Qingyao really didn't know what Zhou Congwen was thinking about, such as demagnetization and magnetization, he was very clear about everything.

Does this have anything to do with cardiothoracic surgery?

In fact, cardiothoracic surgery rarely deals with the magnetic chamber. There is only one cardiac magnetic chamber intersection, and there are not many patients undergoing such examinations, and it can even be said that there are fewer Tebi.

But Zhou Congwen knew it and knew all kinds of data well.

"I was scared to death at that time. I was not afraid of spending money. The impact of 500 kilograms... Although I was in good health, at least I was a fracture." Zhou Congwen said with lingering fear after talking to Yuan Qingyao for a little bit.

"Patient family..."

"I won't talk about this." Zhou Congwen was unwilling to mention the complaint about himself, so he smiled, "So I guess my obsessive-compulsive disorder has accumulated bit by bit. For example, if I take a patient for examination, I would instruct everyone in the corridor not to enter the computer room, for fear of accidents."

"Hahaha." Yuan Qingyao remembered that Zhou Congwen was extremely strict with the surgical patients before the operation, and seemed to have some unnecessary measures, and finally knew where obsessive-compulsive disorder came from.

"Is obsessive-compulsive disorder? Actually, it is not embarrassing to say it. Do you know what hospital is the most frequent hospital in the world with doctors' suicides?" Zhou Congwen asked.

"..." Yuan Qingyao shook his head in a daze.
