The human body is an organic whole organ, not working alone, but coordinating with other organs and body tissues.
The problem of human body coordination is solved, and finally the function simulation of artificial organs is realized. This problem is closely related to the consumables of artificial organs.
To simulate the function of natural organs, it is better to simulate several natural organs, namely heart, kidney, liver and eyeball, only by relying on the current chemical industry.
Even these four relatively simple organs are barely simulated by a large number of enterprises, such as the United Academy of Sciences and the Academy of Engineering.
This reluctant simulation has led to the problem of consumables. Many artificial organs are difficult to meet the needs of the human body. Hormones, organic substances and compounds can be supplemented in vitro, which forms consumables.
For example, the hormones produced by the kidney include renin (raising blood pressure), prostaglandin (lowering blood pressure), erythropoietin, and 1-hydroxylase (regulating calcium and phosphorus metabolism). The renal gland secretes mineralocorticoids, glucocorticoids and a small amount of sex hormones.
These seven hormones can’t be synthesized by themselves, and they can only be supplemented in vitro.
Either the artificial kidney is equipped with hormone system; Or supplement it by taking medicine and injections.
Obviously, neither way is very good.
According to the ideal situation, artificial organs should have 100% function of natural organs instead of this semi-hanging level.
Therefore, micro-hormone synthesis technology has become the only way for artificial organs at present, and nanotechnology is very promising to promote the maturity of micro-hormone synthesis technology.
In Huang Xiuyuan’s future memory, mechanical artificial organs are also called nano-artificial organs because of a lot of nano-technology.
"I said an artificial organ idea" Huang Xiuyuan continued.
At present, in order to simulate natural organs, it is necessary to ensure that the artificial organ department can independently synthesize various compounds. At present, the most promising direction is to create various micro-chemical factories through nanotechnology artificial organs.
"…" Fang Tongfeng and others lost in thought.
At present, nano-robots can only synthesize simple components, and the most complex component is a compound with six original components, which must go through four processes.
In the case of simple and convenient field synthesis technology, the furnace weighs about 7 kilograms, and it is impossible to stuff it into human body with huge roots
There are two main reasons why Huang Xiuyuan is very dependent on the self-sustaining synthesis of artificial organs. On the one hand, it is to reduce the daily troubles of messengers, and on the other hand, it is to prevent accidents
For example, if an artificial organ messenger needs to change consumables regularly in a sudden natural disaster, the consequences may be directly life-threatening.
The messenger in the shipwreck was stranded on a desert island; The eruption of the super volcano has caused thousands of kilometers near the emissary to become a hiding place in a serious disaster area. The emissary may have various problems due to the supplement of artificial organ consumables.
These are all possible problems. In addition, human beings must consider the problem of self-sustaining in order to enter the star.
In Huang Xiuyuan’s vision, human beings have made great progress outside the human body, so we must reduce our dependence on the human body as much as possible.
Artificial organs that need to be replenished regularly will make immigrants have a weakness.
In case of a meteorite impact or a super-large natural disaster on the immigrant planet, these immigrants need to overcome some difficulties
Food is indispensable for human beings, but drugs are not necessarily too few.
In particular, many hormones and organic drugs will have gaps once they are not replenished for a short period of time.
Therefore, it is necessary for the human body to reduce its external dependence.
Extremely extreme ideas, if necessary, it’s best not to eat food directly, to replenish it, and then to rely on the micro-nano factory of human body to ensure life needs.
Chapter six hundred and sixty-two Rebirth
When Huang Xiuyuan and Lu Xuedong inspected the achievements of Lingnan Institute of Materials, Qilu Hospital in Shandong Province also did a relatively hidden clinical test.
Qilu hospital no.6 yard
This hospital area is the clinical testing center of Qilu Hospital, which has been greatly changed since Qilu Hospital was acquired by Shennong Group.
Not only the infrastructure has increased, but also a large number of advanced equipment is very superior to the welfare of workers.
At this time, 12 testers from Yunnan Province and Guangxi Province in the Surgery-Limb Clinical Building of the Sixth Hospital District were resting in the ward.
The ward is a double room.
Inside Room 36 is a middle-aged man in his thirties and a 17-year-old boy, both of whom have a characteristic that they are disabled.
The middle-aged man’s left forearm is missing about a quarter and there is a scar on his forehead. His name is Zhao Shipan, and he is a retired frontier defense engineer.
Due to historical reasons, there are many mines left in the border area near Annan. Zhao Shipan was injured by mines in a bomb disposal industry.
On the other hand, Du Teng, a teenager, is a local in the border area. Because of his youth and playfulness, he strayed into an untreated minefield and his leg was blown off by a mine.
Both of them volunteered to participate in the bionic limb project of Shennongtuan in order to return to normal life.
After a series of operations, at this time, both of them have undergone face examination, and at the same time, they have searched a large number of neuron movement signals
Searching for nerve signals in the process of movement is a process that must be experienced before bionic limbs are installed
Although the major races of human beings do not have reproductive segregation, individual differences are still
For example, muscle strength, muscle cell type, reflex arc sensitivity, five senses and so on are different for everyone.
The most obvious example is that the explosive force of silent sprint is obviously stronger than that of his two races; And the talent of silent swimming is superior.
These two situations are due to the differences in muscle cells and structures of ethnic groups.
There is no artificial bionic limb in the medical field today, but there is obviously still a way to go to replace the natural limb perfectly.
