Urgent! How long do the poisonous properties of sea stingers last

My son (also 10 years old) traveled to Qingdao on the 8th of this month, and after playing at the beach, he had a lot of hard bumps on his body (especially on his legs), which was determined to be "papular urticaria", and he has been seen 3 times so far.

Doctors think that jellyfish bites (not as big as you say) are likely to cause allergies, and they will recur over a period of time, itching, redness, and swelling. But after all, it's "allergies", so there's no need to worry.

Some last for about a week, depending on the individual's physical condition.

There are those selling this medicine by the sea! My mom was stung to buy medicine.

May you be the soon**!

It depends on what kind of jellyfish it is, dizziness, and the doctor will not know.

About an hour If it's a jellyfish, it's hard to say

Jellyfish is a kind of jellyfish, its body is soft and weak, but the magic is that jellyfish can still sting people, so let's tell you why.

The tentacles of the jellyfish are its **. Jellyfish have many stinging cells on their tentacles, and in addition to the cytoplasm and nucleus, there is also a glyptocyst. Inside the filament sac is a disc of small, slender and silky tubes called barbed wire.

There is a stinging needle on the outside of the stinging cell, and when the stinging wire is emitted from the stinger sac, it simultaneously releases a corrosive venom, like an anesthetic needle.

Jellyfish [zhé], like white parachutes, swim around the sea. There are jellyfish distribution in China from Liaoning to Fujian and Guangdong coasts. "April 8, a feed of rain, a Portuguese snake [zhà]".

This is an ancient proverb of Fujian coastal fishermen, which means that after a few showers of heavy rain on the sea in early summer, a large number of jellyfish (snakes) will coalesce and float.

Jellyfish, in terms of animal classification, belong to the coelenterate, with 95% water in the body, and are the animals with the most water. Fishermen along the coast of Fujian and Guangdong in China go out to sea to catch jellyfish every summer, and use bamboo knives to separate the umbrella body and mouth and wrist, and use alum and salt to pickle. The umbrella part is the "jellyfish skin" we eat, and the mouth and wrist part is the "jellyfish head".

The jellyfish's body is soft and weak, but strangely enough, when it comes into contact with its body, it will also sting. It turns out that the tentacles of the jellyfish are its **. Jellyfish have many stinging cells on their tentacles, and in addition to the cytoplasm and nucleus, there is also a glyptocyst.

Inside the filament sac is a disc of small, slender and silky tubes called barbed wire. There is a stinging needle on the outside of the stinging cell, and a group of small fish swims stupidly, and when they accidentally touch the stinging needle, the spiny wire in the spiny sac is launched and stung into the body of the small fish. When the spike is emitted from the gillie sac, it also releases a corrosive venom, just like an anesthetic needle, and the little fish is paralyzed by the stinger and loses consciousness.

Because of the large number of cells on the tentacles, jellyfish can sometimes sting larger fish.

When a person touches its tentacles, it can be stung in a large area due to the secretion of venom, and it will also feel very numb. Some jellyfish (such as the monk's hat jellyfish) can also be life-threatening if they are stung by it. Jellyfish don't have eyes, but they seem to have eyes

When the fishing boat sails by, the jellyfish quickly sinks from the surface of the sea. It turns out that there is a small shrimp on the jellyfish, which has eyes; As soon as there is any movement, the shrimp will see it first. As soon as the shrimp was excited, the jellyfish received this "report" and sank into the sea.

Jellyfish is a large, edible jellyfish, and the head of the jellyfish refers to the tentacle part of the jellyfish. It is the essence of jellyfish, which has a higher nutritional value, and the meat is thicker and tastes better.

The jellyfish head refers to the tentacle part of the jellyfish, and its flesh is relatively thick. Jellyfish head is the essence of jellyfish, taste and nutritional value is better, the general way to eat jellyfish head is to make it into cold salad, cold jellyfish head not only tastes very delicious, but also can strengthen the stomach and eliminate food, many people have a soft spot for it.

How to dispose of jellyfish heads.

Soak for about 10 hours, take the sting head in your hand and use it with your hands, remove the whiskers and white dirt and mucus on the sting head, rinse the sting head, use alum powder, appropriate amount of salt water, spread the sting head, about 10 hours later, take out and drain the alum water, and then according to the weight of the existing stinging head, then put the sting head into the tank, put a layer of salt on the sting head, and sprinkle the top layer with salt to cap, 5 7 days. Take out the biturate, rinse the sting head with clean alum brine, put the sting head into the tank, evenly sprinkle the salt alum mixture, the top layer is capped with salt, after marinating for 7-8 days, wash the sting head with brine, drain the brine for 7 days, turn it up and down, and when you hold it vigorously by hand, the brine is dripping.

The finished product is white, yellow-brown, light brown, no sediment, no sting, no impurities, no peculiar smell.

Jellyfish venom can cause different degrees of damage after stinging the human body, such as sea wasp jellyfish, spiny silk can secrete cobra-like venom, which is the most harmful to humans, and can cause death 5 minutes after stinging. After the monk's hat jellyfish stings the human body, it takes many days for the patient to get rid of the pain. Sand jellyfish floating in the Yellow Sea with the cold current are common along the coast of China, which can secrete peptide poison.

The yellow-spotted jellyfish is mainly distributed in the coastal areas of Guangdong and Guangxi, and has a certain toxicity.

China's sea area is vast, and there are a considerable number of jellyfish sting cases from July to September every year, mainly fishermen who caught jellyfish in the past, and recently there are also stinging patients who swim and play in the water on the beach. For example, on the coast of Qinhuangdao, more than 3,400 patients have been stinged in recent years. According to the statistics of Beidaihe Seaside Hospital, a tourist resort, in the past five years since 1989, a total of 3,030 patients who have been stung have been treated, of which 0 3% have caused fulminant allergic pulmonary edema, and 4 have died (all with severe shock).

Jellyfish are a venomous animal, some can cause us to disappoint and within 5 minutes, some can be injured.

In the deep sea, we will see a blue, translucent object on the surface of the sea, like a large basin of water, it is semicircular, like a parachute, and the body is full of water, that is, jellyfish. Jellyfish sting, and the secret is in its umbrella. There are stinging needles in the umbrella of the sea stinger The stinging is the self-defense of the sea stinger** Once anyone touches the sea stinger, the sea stinger will release a stinging needle to sting the other party

You should know why sea stingers sting, right? This is what I know from books, how about it, are there many benefits of reading books?

Because the tentacles of the sea stinger are its defense**.
