Leeches, commonly known as leeches, belong to the class of annelids leeches. There are 400-500 species in the world, about 100 in China, and 89 species have been found. Most leeches live in fresh water, a few in seawater or salt water, and some are terrestrial and amphibious. Among them are species that feed on blood or body fluids, and carnivorous species that prey on small animals. The largest stalk is about a foot long, and it is a cow leech, which lives in lakes and ponds in the middle and lower reaches of the Yangtze River. The smallest bdelloid rotifer, only the size of sesame, is parasitic on an amphibian called Bufo Cat's Eye in Gongshan, Yunnan. The crab frog leech is an endemic species in China, living in streams in mountainous areas of Zhejiang and Fujian. A Yangtze River gill leech is parasitic on the neck and limbs of turtles in the Yangtze River valley. When the turtle is not in the water for a long time, the gill leech will shrink into a black mass like death, and when the turtle returns to the water, it will resume its normal activities. People's common leeches in rice fields are called Japanese medical leeches, which feed on the blood of people, livestock and frogs. There are some grasshoppers living in the forests of Hainan Island and Taiwan Province Province. They often lurk in the grass and bushes.

In addition to Japanese medical leeches sucking the blood of people and livestock, leeches also infringe on human beings. When people and animals suck raw water, a kind of hirudo living in Yunnan-Guizhou mountains and rivers quickly enters the nasal cavity or oral cavity and adheres to the respiratory wall, sometimes entering the female's body. 1980 In February, scientists in China caught three fish in the Antarctic, and there were leeches on them.

People's understanding of leeches is deepening. As early as the second century BC, it was recorded in Erya that leeches have blood coagulation. Compendium of Materia Medica, written by Li Shizhen in Ming Dynasty, described the efficacy of leeches in detail, and listed many remedies to treat women's moon closure, hemorrhage and postpartum blood halo. According to the modern Pharmacopoeia, leech has the functions of dredging channels and collaterals, resolving food stagnation and removing blood stasis, detumescence and detoxification, and preventing miscarriage. Some people try to treat corneal macula and senile cataract with leeches. In recent years, leeches have been used in microsurgery and plastic surgery. According to the sensitivity of leeches to the changes of chemical and physical factors in water, leeches are used to study water pollution, evaluate water quality and forecast weather. After 1960s, some physiologists found that leeches are excellent materials for studying physiology.

PS: I don't like blood sucking because people eat it-you can't make it eat grass.

What if I am fed by leeches?

1) Never pull the leech, because the more you pull the leech, the tighter it sucks, so that once the leech is pulled, its sucker will stay in the wound, which is easy to cause infection and ulceration.

2) You can pat the leech gently on the upper part of the leech bite or gently pile the soil around the leech adsorption place by hand to make the leech loosen the sucker and fall off. You can also use cool oil, smoke water (that is, water soaked in cigarettes), salt (salt is extremely important in outdoor activities, so it is best to take a small bag everywhere), strong vinegar, alcohol (or white wine), Chili powder, lime and so on. So that it can loosen the sucker and fall off by itself.

3) When bitten, calmly take out the salt you carry with you and sprinkle it on the leech. After a while, you will find that it begins to creep slowly. You can gently move it and add a foot if you want revenge.

4) With fire, leeches will fall, but this method should be especially careful, otherwise leeches will burn themselves before they fall.

5) After the leech falls, if the wound bleeds (basically), press the wound with clean fingers or gauze, and stop the bleeding after 1-2 minutes, and then apply purple liquid (also known as gentian water) or iodine (this is also a treasure in outdoor products, which is very powerful, hehe, I will introduce it in detail later) on the bleeding point, or bandage the affected area with gauze. If you bleed again, sprinkle some Yunnan Baiyao or hemostatic powder on the wound.

6) After leech falls, if there is no bleeding in the wound, you can squeeze out the dirty blood from the wound (MM can ask GG for help if you can't), rinse it with baking soda water or clean water, and then apply iodine or alcohol and mercuric chloride for disinfection.

7) If leeches enter the nasal cavity (you won the first prize), you can use honey to make them fall off. If you don't drop it, you can take a basin of water. The injured hold their breath, invade their nostrils into the water, and constantly stir the water in the basin, so that leeches can be lured out. (No one has tried)

8) If leeches are immersed in * * *, * *, urethra and other places (GG's younger brother has rich blood vessels, leeches often patronize, so it's best not to ask MM for help, which will easily lead to misunderstanding, and his face will be very hot), carefully check the attached parts of leeches, and then drop vinegar, honey and anesthetic (. After the worm retracts, take it out with tweezers.

In short, don't be too afraid to meet leeches, just use the right method. Again, don't bark at the sight of leeches, but play with your fingers or pull them with your hands, which is very bad. Because the leech is only bounced off or torn off its body, and its head remains in the skin, which is easy to cause infection.
