Siheyuan: Rebirth in a prosperous era, great doctors are sincere

The oxygenator, blood pump, microembolizer filter, heat exchange equipment, pipes and cannulas, and vital sign monitoring devices together constitute an artificial heart-lung machine.

A blood pump (artificial heart) is used to replace the heart. It has the function of pumping blood and drives the oxygenated blood in the oxygenator to be returned to the arteries in the body to participate in circulation.

An oxygenator (artificial lung) is used to replace the function of the lungs, inhaling oxygenated venous blood and expelling carbon dioxide.

Li Pingan explained these components to Manager Liu in detail, especially the oxygenator, which has the most stringent requirements. Blood oxygenation and carbon dioxide discharge must meet certain requirements. It has good temperature control effect and small precharge. It has little blood damage, small transmembrane pressure difference, easy operation and easy exhaust.

"Although I can't convince the Sixth Hospital or other hospitals to give you the artificial heart-lung machine aided by the Soviet Union for your research, I know that Union Hospital now has two sets of such equipment!" Li Pingan reminded: "People may use the new equipment aided by the Soviet Union. I won’t give it to you, but you may not be able to take away what the Americans left behind. In fact, if you start from the simple to the difficult, study the American artificial heart-lung machine and then send technicians to the capital to take a closer look at it. The equipment aided by the state is much simpler. You can imitate and improve it, or you can find experts from the Soviet Union to help you solve technical problems and manufacture it."

Relations between the two countries are now good.

The most important thing is that the Soviet Union has not yet realized the huge role of the artificial heart-lung machine. It would be easier to ask them for technology at this time.

current.

Heart-lung machines have few uses.

Take China as an example.

Even if general anesthesia is used during the operation, pure intravenous anesthesia is used.

General anesthesia includes intravenous general anesthesia and intubation general anesthesia. Among them, intravenous anesthesia may not lead to death without an artificial heart-lung machine.

If intubated for general anesthesia, the patient will lose consciousness and be unable to breathe on his own. An artificial heart-lung machine must be used for mechanical ventilation and assisted breathing, otherwise the patient will die due to suffocation.

General anesthesia is the abbreviation of general anesthesia. Whether it is a simple intravenous general anesthesia or a general anesthesia that requires the use of muscle relaxants, in the future, artificial heart-lung machines will be needed for mechanical ventilation and assisted breathing.

However, with simple intravenous general anesthesia, the patient can breathe on his own while being anesthetized.

Therefore, in this case, even if the patient does not go to the artificial heart-lung machine, he will generally not die.

If it is necessary to use muscle relaxants and perform general anesthesia through intubation, in this case the patient's internal breathing will be suppressed and he will be unable to breathe on his own.

Therefore, if the patient does not use the extracorporeal circulation equipment under this general anesthesia, he will suffocate because he cannot breathe on his own, and will naturally face serious consequences of death.

In fact, no matter which general anesthesia method is used in the future, medical staff will use artificial heart-lung machines to achieve mechanical ventilation or assisted breathing. This not only prevents and treats respiratory failure, but also It can effectively reduce the occurrence of some complications.

However, when there was no artificial heart-lung machine in China, even some surgeries that required large thoracotomy could only be performed using intravenous anesthesia, and operations on some organs could be performed in a short period of time.

and so.

Heart surgeries are rare. Even in the Soviet Union, some very difficult heart surgeries cannot be performed. Last year, the artificial heart-lung machine was developed and improved, making it possible to complete many difficult surgeries.

Li Pingan spoke eloquently and elaborated on his views.

Manager Liu said: "We should be able to get the old artificial heart-lung machine from Union Hospital. As for inviting experts in medical equipment from the Soviet Union to come to Shanghai for guidance, it will be more troublesome. Let's give it a try. Maybe they will be happy. Are you here, or can we create an artificial heart-lung machine without the need for experts from the Soviet Union?"

The Modu Medical Equipment Factory is state-owned, so it is easy for them to ask for equipment that has been eliminated from Xiehe Hospital.

Li Ping'an had already said a lot, and his frankness satisfied both Manager Liu and Director Wang. They heard what they wanted to know.

It was a very enjoyable meal.

Manager Liu is very proud to say that their factory is the best medical device manufacturer in China. If the Sixth Hospital needs any equipment or equipment, you can contact him. He will definitely provide the Sixth Hospital with the best equipment and the price will be better. Discounted.

Manager Liu also left his contact information with Li Ping'an and said he hoped to be in touch frequently in the future.

Front-line doctors like Li Ping'an who have been working in the operating room for a long time can give them a lot of inspiration and allow them to produce more useful equipment and equipment.

After dinner, Manager Liu and Director Wang left, and Li Ping'an also returned to the Sixth Hospital.

Ran Qian also specifically asked about the purpose of the two people's visit. Li Ping'an explained the situation. Ran Qian said: "If the experts from the Su State can help them, a domestic artificial heart-lung machine will appear soon. If the Su State doesn't want to To share this technology with them, Modu Medical Equipment Factory will probably have to study it for a year or two!"

"I really hope that this equipment can be domestically produced as soon as possible!" Zeng Jia said: "In that case, I may be able to bring back the technology of using this equipment when I return to the northwest!"

The general manager of Wuzhou Pharmacy left the capital for Shanghai after the pharmacy reopened as a public-private partnership. He and Li Pingan were never able to meet.

but.

Even if they met, it would be of no use. Li Ping'an couldn't go out of his way to develop new drugs for Wuzhou Pharmacy. If they wanted to expand their business scope, they could only apply to superiors such as the local health bureau and commerce bureau.

Boss Zhang of Yizhao Store actually had a chat with Li Ping'an.

After he met Song Cheng, Jin Gui and others, these people all said a lot of good things about Li Pingan. Even Li Cheng also praised Li Pingan's medical skills.

Boss Zhang's father passed away and his mother was old and not in good health. Minor illnesses and disasters often occurred, so he was very happy to make friends with doctors.

He has friendships with some doctors from Union Medical College Hospital, Tong Ren Tang, and Beijing Medical University Hospital.

I heard that Li Ping'an was unique in surgical skills and drug research and development, so I specially found time for Li Chengzuo to accompany him to a relatively high-standard hotel near the Sixth Hospital and invited Li Ping'an.

Li Ping'an knew that Boss Zhang just wanted to get to know him, and he was very happy after he had no special requirements at the moment. He felt relaxed while eating.

The deaf old lady ate some raw red dates sent by Mrs. Xu and drank some cold water. She fell ill again and had diarrhea for several days. Yi Zhonghai asked Yi Zhonghai to get some medicine from the infirmary of the steel rolling mill. Get better.

It was time to stock up on cabbage again, and Qin Huairu's uncle began to buy large quantities of cabbage from the countryside and transport it to the city market for sale.

Now Qin Fen recognizes his identity as a vegetable seller more and more, and even doesn't hide it at all when he goes to the city to buy vegetables.

After the wheat is planted, there is basically no work in the countryside. Even if you stay at home, you can't earn any work points. Qin Fen and his wife often go to the city to transport vegetables together.

The price of cabbage is very different between the countryside and the city. Qin Fen and his wife can make a lot of money!

Now the only private land left by the Qin family in the countryside belongs to Qin Huairu's second brother Qin Huaihe, and it is still cultivated by Qin Fen and his family.
