(A chapter is all poisonous snake bite science.,Won't it be boring to connect with popular science?,Jump if you're bored.,But it's still recommended to take a look.,The skills of the tiger can't be used.,What if this can come in handy)

Lily said, "Then how to deal with being bitten by a snake?" ”

Fang Ye smiled and thought about what to say: "I don't know if you have heard a news story a few years ago, saying that it was a girl who was walking on the side of the road, and her mobile phone fell into the grass, and she was bitten by a snake when she lowered her head to pick it up." After being bitten by a snake, I grabbed it directly and took it to the hospital. ”

Daigo immediately became excited: "Oh, I've seen this news!" It's so domineering! ”

One tourist admired: "I've seen it too!" I remember that the girl was holding the snake with one hand and filling the case with the other, very calm! So I'm impressed. But later it turned out to be a non-venomous snake. ”

Some tourists asked curiously, "Is this method the correct operation?" After being bitten by a snake, catch it, otherwise it seems that there is no way to make serum, and the serum that each venomous snake needs is different. ”

Lin Hao frowned slightly, and muttered in his heart: "Is this the case, it always feels weird?" ”

Fang Ye said with a smile: "After being bitten by a snake, the method of emergency treatment is very important, and there are indeed many misunderstandings in this regard.

The girl in the news is very powerful, catching snakes with her bare hands, but this is a false demonstration, fortunately she encountered a non-poisonous snake, if it is a poisonous snake, it will be dangerous.

Catching snakes requires professional equipment and skills!

Don't learn from her to catch the snake with her bare hands, otherwise the poisonous snake may have been simply bitten as a warning, without releasing venom, nothing, a catch angered the poisonous snake, and was bitten again, this time the poison was injected, or a larger dose of poison was injected, how to say?

In the process of catching snakes and transporting them, secondary injuries may be caused.

Different kinds of poisonous snakes are bitten by different serums, but they are not made from snakes! It's all done early. ”

The flat-headed boy said: "I understand, if you don't catch the snake, you should take a picture as soon as possible, so that you can help the doctor tell what kind of poisonous snake it is, right?" ”

Fang Ye said: "Let's divide the situation. If you happen to use your phone or camera, you can take a picture with your hand, and forget it if you don't have it.

After the poisonous snake bites defensively, it will not stay still, but will leave quickly, and when you take out your mobile phone, call up the camera software, and adjust the shooting angle, the poisonous snake has already run away, and you can take a picture of it when you drill into the grass? Still chasing snakes and shooting?

Panic and exercise can increase blood flow, accelerate the spread of toxins, and delay first aid.

After being bitten, it is best to calm down and first determine whether it was bitten by a poisonous snake, and you can look at the tooth marks of the snake.

The tooth marks of non-venomous snakes are jagged, the tooth marks are small and shallow, and the venomous snake bites generally have 1-4 large and deep venomous tooth marks! The tooth marks are purplish-black, and the nearby skin is purple, swollen, or numb.

If it's a poisonous snake, take first aid measures, then try to minimize movement and wait for rescue!

You should have also learned about some first aid measures after a snake bite, right? ”

The big brother with the national character face said wittily: "Bite your finger and cut it off directly!" ”

"Haha." Fang Ye couldn't cry and laughed, "Big brother, you're a little ruthless, what about biting your hand?" ”

Guozi face thought for a while and said, "Then don't cut it, suck it out." I know this, I need my mouth to be free of bleeding. ”

Daigo said: "I remember seeing this kind of news!" Someone was bitten by a snake when he went up the mountain to chop wood, and he directly cut off his finger with a firewood knife. ”

A tourist next to him nodded in agreement: "Abandon the car and protect the handsome, as long as you can survive!" ”

Now everyone still thinks that "strong man breaks his wrist" is a normal emergency treatment method!

Fang Ye couldn't help but sigh, and felt more and more the importance of popularizing science about the knowledge of venomous snake bite treatment.

"It is absolutely wrong to cut this practice directly, in case it is a non-venomous snake, cutting off the limb may lead to severe hemorrhagic shock or even death, and it will be permanently disabled in the future, it is not a blood loss.

In 94, a child in a rural village in Zhejiang was bitten by a five-step snake when catching a frog, and the father quickly chopped off his son's arm with a firewood knife in order to save the child's life. The snake venom is gone, but a lively and cute child has lost his arm forever. ”

The tourists all showed shocked looks, and gasped one by one: "Hiss~"

"Wow, this kid is so miserable."

Fang Ye said: "The five-step snake just describes this snake as very poisonous, not that it really dies after taking five steps after biting!"

What is this equivalent to, bathing the baby in the basin and throwing the baby out with the dirty water when it is poured out.

If you are bitten by a poisonous snake, take off the jewelry on your hand as soon as possible, because after a poisonous snake bite, the bite site will soon swell, and the blood cannot be circulated if you can't take it off while wearing a ring and bracelet, and you may have to amputate it after a long time.

Then we use the belts, earphone cables, rubber bands, shoelaces and other things that we often carry with us to make a binding and ligation. The sooner the ligation is done, the better! It can stop the spread of snake venom in time.

It is located 5-10 cm proximal to the wound and bites on the finger and pierces the base of the finger. It is important to grasp the tightness of the ligation, not to tie it too hard, just like a blood draw, and to be able to put a finger into it.

Tie for 40 minutes for 1 hour, and loosen for 10 minutes, otherwise tying too tightly for too long may cause distal hypoxia necrosis.

Then rinse the wound repeatedly with water! Soapy water, salt water, or potassium permanganate solution is better.

Just now the eldest brother said that sucking with the mouth, the mouth sucking can play a certain role when it is just bitten, and it is useless to suck it again after it spreads, because snake venom is chemically combined, and it cannot be completely discharged by physical means.

And be careful not to have bleeding gums or anything, and every time you suck out and spit out the snake venom, you must rinse your mouth and clean your mouth, because the sublingual veins are rich in blood vessels and have strong absorption, otherwise you may be poisoned twice.

There is no need to worry about swallowing a small amount of snake venom into the stomach, because the snake venom will be broken down by stomach acid after entering the stomach, and poisoning will not occur. Except for those with gastric disorders.

Let's talk about expansion and fire detoxification!

Both methods are effective, but the average person should not use them, and only professionals are recommended to use them.

The principle of expansion and mouth suction and detoxification is the same, but how long and deep the expansion is cut, it is difficult for ordinary people to grasp, the shallow cut has no effect, and the deep cut is not conducive to recovery, and some snake venom is blood venom, there are anticoagulant substances in the venom, and the incision of the wound will make the blood continue to flow out and aggravate the injury.

The principle of fire detoxification, because the component of snake venom is protein, fire can denature and inactivate the protein.

Some snakes have long fangs and are so deeply poisoned that the fire can only burn to the surface, and cannot destroy the venom at all.

However, for some venomous snakes with shallow fangs and small amounts of venom, the method of burning has a miraculous effect, generally using a few match heads to ignite on the wound, and destroying the snake venom with the high temperature of instant burning.

However, if ordinary people use it, it is likely to be not well mastered, causing skin tissue burns and infection, and it will not destroy snake venom, so it is best to only use the previous methods!

Just like the blind man's roundhouse kick in League of Legends, the professional player uses it steadily and ruthlessly, and determines the battle situation with one kick, and the bronze blind man may touch his eyes and send it away.

After the emergency treatment, go to the hospital immediately! ”

After saying a long line, Fang Ye took a breath, and the tourists applauded in admiration: "I've learned, I've learned!" ”

"Thank you, Principal, for correcting a lot of misunderstandings I know!"
