Sleepless Doctor

"Doctor Wu, your eyes are really bright." Cheng Yunhai's pain seemed to be a lot lighter. He held the bag and tried to squeeze a smile. "It is indeed an artificial heart."

"It's no wonder that the artificial heart technology is not mature now. It can only be said to be a way to barely maintain vital signs." Wu Mian smiled and said, "With your financial conditions, heart transplantation does not seem to be a problem. China can't wait for a suitable one. The donor can go to the U.S. or Brazil."

"Doctor Wu." Cheng Yunhai smiled bitterly, "Your curiosity is really strong, just like a scientist I know."

"This is to ask about the medical history. It involves your treatment after recovery. You must be cautious." Wu Mian ignored the faint sarcasm in Cheng Yunhai's words.

"I asked my attending doctor, a cardiologist at Cedarsene Medical Center."

"Who?"

"Doctor Damon Rich."

"Oh."

"You know?"

"Taught him to have a complicated congenital heart disease operation." Wu Mian smiled slightly, "You continue."

Guidance, Tao Ruo heard clearly this time.

If it is the first contact, Tao Ruo would think Wu Mian is bragging. But after contacting him for so long, he knew Wu Mian's ability, but he didn't expect that he would use the word guidance.

"..." Cheng Yunhai glanced at Wu Mian, the two of them collided, and then Cheng Yunhai said, "Dr. Damon Rich said that after changing the heart, some people's personalities will change. Regardless of whether it is in the medical field, There is still no detailed theoretical basis in the biology community."

"Damon is right." Wu Mian said, "but the symptoms are not necessarily, he is talking about extreme cases."

"I can't accept this kind of change." Cheng Yunhai said, "So I set aside and chose an artificial heart."

"Your company is doing similar research?" Wu Mian asked.

"Yes." Cheng Yunhai did not evade, and directly admitted.

"What was the previous diagnosis?"

"Dilated cardiomyopathy is in the stage of end-stage heart failure."

Wu Mian nodded.

"Artificial heart?" Tao Ruo smiled bitterly when the two of them were silent and there was a short gap, "Yunhai, are you still hiding this from me?"

"Old Tao, you didn't ask if it was." Cheng Yunhai smiled.

"It is recommended that after the operation is done here, the ischemic symptoms of the legs are relieved, and a heart transplant operation should be done."

"The research in the laboratory has made breakthrough progress." Cheng Yunhai said, "I should be the first experimental subject within 3-5 years."

"..." Wu Mian was a little helpless, how could Cheng Yunhai be so paranoid? What day is it today, I have encountered so many paranoid patients.

"In ancient Greek mythology, Tanatos, the **** of death, had an iron heart and a copper heart. Dr. Wu, don't you think it's cool to use an artificial heart?" Cheng Yunhai smiled.

"Tanatos... it's complicated to say. Iron Man also uses an artificial heart. Do you want to be such a person?" Wu Mian asked.

"Of course, if there is a chance, who doesn't want to. It's just that controllable nuclear fusion will always be 50 years away from success. It is estimated that it will be difficult to become Iron Man." Cheng Yunhai said.

Tao Ruo is very curious, but it is hard to see Cheng Yunhai's "heart".

Everything today seems to be in the world of science fiction, everything is so unreal.

"Can I take a look at your artificial heart?" Tao Ruo is hard to say, but Wu Mian has no taboos, he asked.

"No problem." Cheng Yunhai opened the special backpack, which contained a "heart" painted in red.

Obviously, this heart has undergone a special appearance treatment and looks exactly the same as the heart in people's impression, but it is static and does not "pump pound".

"Your thoughts are very delicate, very literary." Wu Mian smiled.

"At least it makes me look like a person... I'm not talking about this, but I look like myself."

"Permanent? How long after surgery?"

"Well, it's a permanent type. It's been 4 years since the operation."

"It's very rare, I can only say that you are lucky." Wu Mian smiled, "I have great hope for the success of the operation."

"The third-generation test product still did not solve the thrombosis problem, but it is already very good. The laboratory has four generations of products," Cheng Yunhai said.

"Ms. Wu, it has something to do with lower limb necrosis?!" Tao Ruo couldn't help asking.

"Yeah." Wu Mian nodded, "The heart is like a pump, which contracts and dilates day and night to provide power for blood circulation. The artificial heart is designed to build a heart-assisted flow channel to help realize blood circulation."

"The blood pump is connected to the patient’s own heart by two artificial blood vessels. Blood flows from the ventricle through the blood vessels and flows into the blood pump. The impeller in the blood pump rotates to generate centrifugal force to pump the blood out and flow into the ascending aorta through the outlet vessel, partially or completely replacing it. Heart function."

"The blood pump is connected to a controller outside the body through a pump cable, and patients need to carry the controller with them."

"The controller weighs about 3kg, and contains a battery pack to provide power and a speed control system. The first and second-generation artificial hearts are pulsatile pumps and axial flow pumps. The first-generation pulsatile artificial hearts are also called positive displacement pumps. It is large in size and not easy to implant."

"The second-generation artificial heart has become smaller, but the impeller speed is high, which may damage the red blood cells and blood coagulation system, and easily cause thrombosis."

"The third-generation artificial heart device is small in size, easy to implant, and produces almost no heat during operation. Due to the use of non-contact bearings, the core parts can rotate without any mechanical contact with surrounding components, reducing mechanical friction. The problem of wear and tear. Because the core parts are not in direct contact with the blood, the thrombosis problem has also been significantly improved."

"But looking at Mr. Cheng's situation, although it has improved, the blood clot problem is still a headache." Wu Mian said.

"Doctor Wu, you are right." Cheng Yunhai said, "However, there are already laboratory samples for the fourth generation of products. If the operation is successful here, I will do artificial heart replacement as soon as possible~www.wuxiaspot.com~Sigma Lab "Wu Mian asked.

"You know?" Cheng Yunhai was slightly surprised, how could this young man know everything.

"Visited." Wu Mian said, "This is not a military product. I can look at it from a distance and see some of the corresponding data. The fourth-generation product is good, but slightly more expensive."

Cheng Yunhai frowned, sweat already oozing out of his forehead.

"Do you usually take oral medications or intramuscular injections?"

"Oral, I never gave up in my heart." Cheng Yunhai said, "I still think about becoming a normal person one day, instead of relying on injections to maintain."

"Your choice is right." Wu Mian said, "but oral drugs can also be addictive."

"Well, so I control the dosage of the medicine." Cheng Yunhai said, closing his eyes, "But, I'm so tired."
