Chapter 473 Endoskeleton

Take 5 anthropomorphic bodies from the anthropomorphic body storage room.

Li Qingye came to an exclusive experimental area that had already been prepared, and more than a dozen scientific research assistants were ready.

"let's start!"

Following his order, the research assistants began to get busy.

They lifted an anthropomorphic body out of the life support cabin, inserted various life support equipment, and then inserted a special syringe needle into the anthropomorphic body's vein.

Immediately afterwards, a cylindrical container was taken out from a biological safe, which was about the size of a large thermos.

Connect the container to the syringe.

Press the start switch, and the special liquid in the container is injected into the anthropomorphic body little by little.

Another research assistant is checking the feedback data of the artificial brain.

A large number of free cells in the special solution entered the whole body of the pseudo-human along with the veins.

About an hour passed.

"Chairman, cartilage tissue has begun to form."

Li Qingye turned the chair, looked at the holographic body structure model formed by the scanning equipment, and a layer of cartilage began to form under the dermal tissue that simulated the surface of the human body.

These cartilage tissues are distributed in a fibrous structure, starting from the surface of the dermis, and then spreading to the muscles and internal organs.

"Report, the weight of the test subject is increasing..."

"Report, the height of the test subject..."

As the chondrocytes continued to build cartilage tissue in the experimental body, the body weight of the experimental body increased a little bit, and the height and body shape also swelled a little bit.

until 36 hours later.

The chondrocytes completed the construction of the endoskeleton. At this time, the body weight of the experimental body increased by 18.3%, the height increased by 3.2 cm, and the body contour became much thicker.

In short, get stronger.

At this time, in the scanned holographic body model in front of Li Qingye's eyes, the white lines represent cartilage tissue, and these cartilage tissues have densely covered the entire body of the experimental subject.

"Injecting neural network building cells."

"Yes."

These cartilage tissues are integrated with muscles, blood vessels, bones, and internal organs to form an artificial skeleton fitted into a human body.

And this artificial skeletal system is called "endoskeleton".

Endoskeleton, as the name suggests, is the bones in the body, which is used to distinguish exoskeleton and autologous bones.

The reason why Li Qingye developed the endoskeleton is to strengthen the human body, which is actually one of the components of bio-based armor.

The old version of bio-based armor is mainly through the biological exoskeleton covering the body surface, plus various functional symbiotic insects, symbiotic bacteria and biochips in the body.

In practice, although the old version of bio-based armor has excellent functions in all aspects, there are still some shortcomings.

For example, if the body is violently hit, it will also cause coma, internal organ damage, bone fracture, blood vessel rupture, and even death.

Although Homo sapiens' security forces rarely come into close contact with the enemy, it doesn't mean that this problem can be ignored.

Because there is another big application field of bio-based armor-space suits.

Especially in the ascent phase of the launch vehicle, or the orbital airborne phase, overloading is basically a common occurrence.

At present, the Medan Aerospace Group, a subsidiary of Homo sapiens, produces ape-eating eagle launch vehicles with a maximum overload of 4.8G in the atmospheric stage. For astronauts equipped with bio-based armor, this overload is nothing.

But another subsidiary, the Dandelion Aerospace Group's aerospace airship and aerospace transport aircraft, has a maximum overload of 6.7G during the atmospheric ascent phase, and if an emergency suborbital airborne, the maximum overload can even reach 12.5G.

If the overload exceeds 8G, the protective effect of bio-based armor will decrease. If the overload exceeds 12G, even with bio-based armor, astronauts may still fall into coma, black vision, red vision, and induce cardiovascular disease.

Through a series of feedback data from practical applications, various aerospace subsidiaries have discovered that the current bio-based armor has certain limitations.

Its limitation is that when the overload exceeds the threshold, various organs of the human body will be compressed, which will lead to dyspnea and abnormal blood circulation.

In order to solve this problem, the endoskeleton system came into being.

The endoskeleton system, which is composed of special cartilage tissue groups, is similar to a sponge in its nanostructure, and will store a certain amount of physiological saline after it is formed in the body.

Once encountering a sudden external force, the soft inner skeleton will instantly harden and tense the body.

The stronger the external force, the harder the endoskeleton system will become, which is similar to the force mode of non-Newtonian fluid.

However, there is a limit to the pressure of the endoskeleton. If the instantaneous overload exceeds 30G, even if there is an endoskeleton system, the body will be overloaded and crushed.

For this point, when Li Qingye and a group of researchers designed the endoskeleton system, they did not expect too much. It can achieve a safe overload below 25G, which is the greatest value of this system.

Of course, the endoskeleton system can be used for more than just anti-stress.

In fact, the endoskeleton system has many functions, including load resistance, bulletproof, impact resistance, heavy pressure resistance, and improvement of athletic ability.

With the cooperation of biochips, it is possible to lift a weight of 500 kilograms without an exoskeleton, and jump from a height of 10 meters without any damage to the body.

At the same time, with the endoskeleton system, after the exoskeleton is equipped with bio-based armor, the cooperation between the body and the exoskeleton will be more perfect.

But all of this is the case of supercomputer simulation.

In reality, experiments are underway now.

Injecting neural network construction cells into cartilage tissue is another key point of the endoskeleton system, which is to allow cartilage tissue to be completely integrated with biochips.

Only when the neural network connection is completed can fine control of cartilage tissue be achieved.

Li Qingye and his scientific research assistants looked at the feedback data of the artificial brain, which simulated the cartilage tissue inside the human body and connected the cells with the biochip bit by bit through the neural network.

This process took 8 hours.

When the last part of the cartilage tissue is connected to the neural network construction cells, the implantation of the endoskeleton system inside the human body is officially completed.

"Test blood regulation."

"OK."

The part of the cartilage tissue that wraps the blood vessels, through contraction and extrusion, successfully reduced the blood supply to some parts, or even directly blocked the flow.

Then artificial cardiopulmonary resuscitation is performed directly in the body. The endoskeleton system can directly squeeze the heart, and there is no need for external compression.

The next step is to test artificially assisted intestinal peristalsis, varicose vein repair, respiratory foreign body discharge, and assisted breathing.

Among them, the endoskeleton system implanted in the alveoli is the most special part, because this part of the endoskeleton can also have another effect, which is to block the direct contact of the external fluid with the alveoli.

At the same time, the upper respiratory tract has been implanted with a special symbiotic fungus, which can penetrate the mycelia into the alveoli, absorb oxygen from the liquid, transport the oxygen to the alveoli, and expel the carbon dioxide released by the alveoli.

In other words, humans at this time can breathe directly underwater.

In order to solve the problem of liquid exchange caused by underwater breathing, the endoskeleton system can temporarily open the upper respiratory tract and esophagus, and at the same time temporarily close the connection between the esophagus and the stomach, allowing oxygen-containing liquid to enter from the respiratory tract, and carbon dioxide-containing liquid to be spit out from the esophagus.

Of course, if this special underwater breathing mode is in a natural water body, the human body's activity function will be greatly reduced, because the oxygen content in the natural water body is too low, and there will be insufficient oxygen supply.

Without the assistance of the endoskeleton system, underwater breathing or even swimming is impossible, only floating on the bottom of the water.
