I did this human body freezing in the hope that technology could heal the destroyed heart in the future, and when Wen Niu had a genetic disease, she would be revived.

People have confidence in the future of science and technology, and the development of the post-technology era is absolutely unimaginable, just as we could not imagine the genetic engineering of airplanes and spaceships before.

The world is changing with each passing day.

Scientists can now theoretically preserve the function of the brain to the greatest extent after clinical death, and in the future, after the human body is rewarmed and resuscitated, the human body can be repaired through related DNA repair, stem cells and other technologies to achieve resurrection.

Wen's father and Wen's mother agree with their daughter's choice.

They also know this frozen man technique.

Just last month.

At 4:01 a.m. on May 8, in the comfortable medical ward of the East Campus of Qilu Hospital of Dongshan University, Zhan Wenlian stopped breathing. Ms. Zhan Wenlian, who was dying of lung cancer, became the first "patient" to be frozen in China and waiting to be revived, which is of breakthrough significance. Ms. Zhan Wenlian's freezing was jointly completed by Yinfeng Life Science Research Institute and Qilu Hospital of Dongshan University.

As early as 2015, one of the editors of the sci-fi "Three-Body Problem", Chongqing female writer Du Hong accepted the American cryonics technology, becoming the first person in China to accept the technology, but unlike Ms. Zhan, Du Hong's body was sent to the Alcor headquarters in Los Angeles (one of the world's largest frozen human research institutions) in a frozen state. The head of the body is to be separated and kept in a special container for a liquid nitrogen environment at -196C

In fact, in 1967, there was the world's first case of frozen people", James, a bedridden lung cancer elderly, believes in "The Prospect of Immortality Forever": death is a gradual process, and if the body is frozen fast enough, death can be reversed. As a result, James, who was approaching his deadline, decided to have the doctor freeze his body after his death.

Xi Ming began to study Wen Niu's freezing work.

Waiting for a breakthrough in heart technology, waiting for the day when incurable diseases can be treated, and then resurrect Wenniu.

Is cryonics simply a matter of cooling and preservation?

Of course not, the natural freezing method can refrigerate the body, but the freezing process can cause irreparable damage to the body. The human body contains a large amount of water both outside and inside the cell, and if it directly enters the liquid nitrogen environment, the water in the body will quickly form ice crystals, puncture the inner wall of the cell, and cause permanent damage to the whole body. However, the water in the cell expands after freezing, which poses a greater threat to the cell and the DNA material in the cell. In addition, icing can dehydrate cells, which will eventually lead to cell death.

Therefore, the core of freezing technology is to prevent the human body from being damaged, and the experimenter must first drain the blood and water in the body before freezing, and replace it with antifreeze that is not easy to freeze.

The doctor first gradually replaces the blood in the body with a diluted protective solution, and then uses an instrument to open the common artery and common vein in the neck of the deceased body, forming a fluid infusion circuit to inject the protective solution. When the concentration of the protective solution in the human body reaches the requirements of body preservation, continue to monitor the concentration of the protective solution in the intravenous output fluid, and when the concentration of the protective solution in the output liquid is consistent with the input concentration, it means that the human body water has been completely replaced.

Perfusion for more than 4 hours, the whole process needs to be done at freezing low temperatures close to 0 degrees Celsius. The medical team's experts will use dry ice to quickly cool the frozen person to -130C, and then put them head-down into a liquid nitrogen dewar at -196C to complete the freezing process.

The head-down is to ensure that the head can be protected in the first place in the event of an accident such as a liquid nitrogen leak.

Chinese human refrigeration company, Yinfeng researcher issued the human cryonics charging standard, liquid nitrogen tank 400,000, program cooling equipment 400,000, extracorporeal bypass machine 1 million, ventilator 780,000, laboratory construction 5 million, according to the experimenter, each freezing operation, only cryonics to 230,000, and every 10 days ~ 15 days to supplement liquid nitrogen, this cost is about 50,000 per year.

Therefore, cryonics technology is considered a risky project for the rich, and it cannot be supported without money, and what Ximing lacks most now is not money!

Xi Ming will not choose a Chinese cryonics company, it feels too risky, because the domestic case has only been completed.

June 18, 2017.

New York, USA.

Wen Qianjin stopped beating and breathing in her hospital bed, and doctors pronounced her clinically dead, but this time, it cannot be said that she was "gone forever." ”

Because a staff member immediately carried out an operation on Wen Hanxiang that grew up to hundreds of hours, and the human body was frozen.

Freezing first started with her heart and lungs, and they slowly lowered her body temperature to 3 degrees Celsius and then removed all the water from her body.

A tube is then inserted into the body to drain the blood, while a glycerin solvent is injected instead of the blood to prevent frostbite. The blood draw procedure involves making sure that the body is at a low enough temperature so that the blood circulation stops and does not harm the brain cells, and these wires behind the tubes are used for data collection and electronic testing.

Scientists go through a rigorous computer to examine all kinds of data from the frozen human body.

That's when the doctor inserts a tube into the patient's body to draw blood, and at the same time injects a glycerol solvent into the blood vessels instead of blood.

The body temperature was lowered to minus 196 degrees Celsius.

……

Many insects and lower creatures freeze in winter and come back to life in spring.

Wen's father and Wen's mother comfort each other that their daughter will wake up again one day.

The current daughter is only a short rest for a while, if there is an accident in the future, at least she is still there, and she can go over to see her daughter one day.

When Wen Qianjin froze, she looked very peaceful, as if she was usually asleep, and her beautiful face was eternal.
