【3.Artificial pancreas】
【pancreas produces insulin】
【If your pancreas doesn't do this, you'll need artificial injections of insulin】
【Therefore, a daily routine that diabetics must do is to check their blood sugar and inject insulin if necessary】
【But the artificial pancreas can automatically release insulin into your body】
【This device looks like a regular insulin pump】
【It can penetrate the skin and continuously release insulin into the body】
【And it constantly monitors the blood sugar level and adjusts the amount of insulin released according to the blood sugar level.】
【Therefore, even if the person wearing the device falls asleep, there is no danger of their blood sugar dropping to very low levels and causing them to faint.】
【The good news is that artificial pancreas is not in the early stages of research】
【This device does exist and has been approved for sale by the FDA】
【2.Artificial eyes】
【As has been pointed out before, it is more complicated to make the deaf hear the sound, but to make the blind see the picture.】
【When people lose vision, their retinas no longer send signals from photoreceptors to the brain】
【In order to create artificial eyes, we first need to understand how the retina obtains these signals, and this is the key that scientists have not yet solved.】
【Until recently, scientists had achieved this, at least in mice and monkeys】"313"
【This artificial retina has a chip that can convert images into electronic signals, and its micro-projector can convert electronic signals into projection light.】
【These artificial eyes have indeed restored the sight of blind mice】
【The monkey's retina works very similarly to that of humans, so subsequent experiments on monkeys gave hope for eventual success in humans.】
【1. Finger memory】
【When fen programmer Jerry Jalava got into a car accident in 2008, he faced a double tragedy】
【First, he lost his fingers, a big problem for someone who relies on typing to survive】
【Second, he had to deal with a medical team with an excess of humor.】
【After learning about his experience, a surgeon actually suggested that 1ava should go out and buy a"B-finger drive""】
【But Jalava did not reject the doctor's suggestion (due to the actual situation of the injury, it was difficult to refuse), but took this suggestion as his own expectation】
【He decided to give it a try and actually put two gigabytes of digital memory into his implanted finger】
【He can now simply peel off his fingernails to expose the USB plug and insert his fingers into the computer connection】
【He can also remove the entire finger at any time and lend it to a friend】
【What's next??】
【Jalava plans to upgrade with RFID tags on fingers and add wireless support】
【He wanted to expand capacity, but the method was naturally very nonsensical.】
【If he wants more space, he still has 9 fingers that can be cut off and replaced with removable storage.】
【......】
【Having said all this, do you think that any organ can be artificially made and replaced?】
【If you think so and indulge your body, you are totally wrong.】
【There is an organ that is extremely difficult to replace with artificial organs】
【That's the kidney, that's the kidney】
【Please watch a short video below to understand why kidneys cannot be replaced by artificial organs in a short time. 】
The text in the light curtain disappears.
It’s time again for the video-watching session that the ancients loved.
Opening lightning strike.
A skeletal human skeleton model appears directly on the screen.
The perspective focuses on the two kidneys inside the skeleton.
【Why can't humans create artificial kidneys?】
【Even a life-sustaining heart can be made, but why can’t a tiny kidney be made?】
【In fact, everyone knows】
【The essence of an artificial heart is like a water pump, it just transports blood throughout the body.】
【The work content is very simple】
【Keep things running normally and nothing will happen to people】
【However, the job of the kidneys is very complex】
【Humans have two fist-sized kidneys, which are like sewage treatment plants in the human body.】
【Its main function is to filter and purify various impurities and water produced by human body metabolism, while maintaining the body's electrolyte balance.】
【So how much work does the kidney do?】
【The kidneys can filter 1.2 liters of blood every minute and can purify 200 liters of blood 24 hours a day.】
【Equivalent to the capacity of 400 bottles of mineral water】
【In one day and night, the blood in the whole body can be filtered 40 to 50 times】
【And every moment, the kidneys are working under high load】
【Open all year round, it can be called a model worker for the human body】
【So the workload can be imagined】
【So is there an artificial kidney?】
【An extracorporeal hemodialysis machine that replaces the kidney, that is, a blood purifier, weighs about 200 kilograms, covers an area of one square meter, is about the same size as a refrigerator, and has a power of 1.5 kilowatts.】
【Therefore, it is very difficult to reduce such a big guy to the size of a kidney.】
【There is also the problem of power consumption. Only nuclear batteries can maintain the calculation.】
【The key nuclear battery cannot be manufactured now.】
【Therefore, artificial kidneys are still under research, and it may be possible in the future.】
【But all we can do now is to take care of our own waist】
【Once the waist is wasted, it is really useless】
【......】
The video inserted at the end can make the ancients confused.
Can anything be said to be artificial?
Why can’t the most important kidney be made!
"I'm done! Everything can be made, but the most important thing, the waist, cannot be made! I hate it"
"Alas, I share the same sorrow. I will recite it every day from now on and take care of my kidneys."
"I’m so angry. From today on, I’m going to quit sex! Take good care of your waist starting now!"
"You guys just stand still and keep chatting while I go buy some wolfberries."
"Dog thief! You didn't even take me with you!"
"together together"
"......"
Men in ancient times have never felt that their waist was so important.
In ancient times, entertainment activities were scarce, and the biggest entertainment activity for ordinary people was to make little people at night.
As for that activity, everything is good, but it hurts the waist.
But now, the light curtain tells them that most of the human organs can be replaced with artificial ones, except for the kidneys.
Problems that cannot be solved even by the medicine of later generations were even more impossible in ancient times.
Ordinary people who don't have money can only try their best to quit sex and take care of their kidneys.
And the dignitaries are crazy about buying tonics.
Especially the tonics for the kidneys, the prices skyrocket!
Qin Dynasty.
Ying Zheng coughed twice in embarrassment. (To read Baoshuang novels, go to Feilu Novel Network!)
He hesitated for a moment and conveyed his will in a low voice.
"Today evening, we rested in the study and told our concubines not to wait any longer."
After giving the instructions, Ying Zheng felt relieved.
For the first time, he realized that having a group of wives and concubines might not be a good thing.....
For example, it is easy to overwhelm a person's waist, leading to a short life.
Fortunately, he has many heirs and will not need to work so hard in the future.
You can also ask the imperial doctor to prescribe some medicine to take care of your body.
Han Dynasty.
Liu Bang's expression froze.
If the waist is useless, it is really useless.
These words calmed him down!
At his current age, he is indeed not as powerful as he was when he was young.
See the words on the light screen again.
Liu Bang fell into deep worry[]
It's over, I want to protect my waist, I can't let it go to waste.
Liu Bang began to plan a health regimen in his mind.
First of all, we must control ourselves and then take medicine...
Three Kingdoms period.
Cao Cao raised his forehead, what is this?
Disturb his pleasure!
Rebooting is impossible, so we can only think of ways to supplement.
Cao Cao was surprised and happy when he thought of this.
Fortunately, Hua Tuo was not killed.
He waved his hand quickly:"Quick, hurry up, chase Hua Tuo, and ask him to prescribe the medicine for Gu before leaving."
All the civil servants and generals around him were dumbfounded. prime minister...
Can you give us the prescription by then?
Tang Dynasty.
Wu Zetian looked indifferent.
Fortunately, she is a woman and doesn't have to worry too much about this problem.
Then play music and then dance!
You can't enjoy the country you finally grabbed.
Ming Dynasty.
Empress Ma whispered and laughed:"Chongba, I asked you to marry so many wives and concubines, so be careful about your waist.""
"Girl, there are so many people, what do you say?"Zhu Yuan 4.4 looked a little confused.
He only had 22 wives and concubines.
Is that many?
Besides, he was strong, so he needed to worry??
Another period.
After Zhu Houzhao read it, he didn't care at all.
He even looked at the eunuchs around him. He shouted:"The Leopard Room will arrange a few more maids tomorrow. I want to visit them.""
The eunuchs all looked at each other in disbelief.
"Your Majesty, you have forgotten that Guangmu said that you still insisted on being lucky and wishful after getting sick. Only then, only then..."
The eunuchs were all stunned.
They rarely see unrepentant people, but they happen to have them right in front of them.
"So scared! I no longer play the role of a fisherman, I will never touch the water again, let alone get cold."Zhu Houzhao was full of pride.
When he learned that he had fallen into the water and contracted an illness because of playing the role of a fisherman, he made up his mind not to go to rivers, lakes or seasides for the rest of his life.
Anyway, the light curtain admitted that he was the most playful emperor.
As the saying goes. A dead pig is not afraid of being scalded by boiling water.
Zhu Houzhao said,"It doesn't matter, just play!"
