Two days ago, when Xiaobian went to climb the mountain, unfortunately, because of the shoe inconsistent, "Bubble" was grinded on his feet. After returning home, I also have a lot of curiosity when I feel uncomfortable -what exactly is this "blisters"? Why do humans grow "blisters"?

The "blisters" we generally say refers to the phenomenon of a small envelope accumulated in the surface of the skin. "Bubble" scientific name is blisters, which are divided into two types: blisters and viral blisters caused by the damage of the skin.

After growing blisters on the skin, we may feel that some blisters "do not feel", or they may feel pain or itching, and even more may cause fever. Today, let's take a look at what is going on with the "blisters" on our body.

What exactly is "blisters"?

Medically, "blisters" can be understood as a kind of skin damage symptoms. In fact, shepeshed from raised from the skin surface, that is, blisters growing on the normal skin. Bles are often accompanied by epidermal stripping, and the blisters induced by the virus are better on the skin wrinkles.

There are many incentives for blisters. Blinds caused by the skin are created, common incentives include abrasion, burns, sunburn and allergic reactions. The viral blisters, as the name suggests, are caused by the virus. For example, chickenpox virus can make people grow blisters on their skin.

How is "blisters" formed?

The mechanism of blisters is very complicated. Let's take burns blisters and friction blisters as examples ——

1. Scald Blossom: In the early stage of burns, the scald area and the surrounding capillaries were dilated and permeable. In layman's terms, the blood vessels became "filter". A large amount of ingredients in the blood flow through the "filter" and flow between the skin and flesh from the blood. These liquids flow under the skin and push the thin epidermis to form edema or exudate from the wound position. This is the burns.

2. Rubbing: When the skin is strongly friction, the thinner skin will break off, and the thicker skin will be pulled away from the flesh under the skin. The tissue of the subcutaneous tissue will flow out of the tissue liquid. If the skin falls off thinly, the tissue liquid will flow out; when the skin is thicker, the tissue liquid will fill the gap between the skin and the flesh and flesh to form blisters. This is frictional blisters.

What is the "water" in the blisters?

The liquid in the blisters is composed of tissue liquid and some components of the blood, and the ingredients are very complicated.

According to research by Liaoning University of Traditional Chinese Medicine and Nantong Medical College, the blisters contain a large amount of protein, such as fibrous binding protein, fibrinogen, semi-milk gelcin-10, touch protein, protease inhibitors, α2-HS glycoprotein, α2 -HS sugar protein, cluster protein, etc., some of which have positive significance for the healing of the wound.

For example, the original fiber protein has the function of promoting blood condensation, promoting wound repair, and anti-infection; semi-milk gelcin-10 has the function of regulating immunity and inflammatory reactions; tactile protein has the function of anti-infection and stable internal environment; cluster protein has regulation The function of cell growth and apoptosis.

What do you want to deal with blisters?

Finally talked about what we all care about -what do you do with blisters? I checked the information of the experts and made the following suggestions for everyone:

(1) For viral blisters and blisters caused by allergies: If it feels itching, it may be viral blisters or allergic reactions. At this time, try not to scratch, you should seek medical treatment as soon as possible. The doctor will prescribe the appropriate ointment to apply it.

(2) For other skin damage -type blisters: If non -allergic skin damage blisters are arising, you can consider handling it yourself. If the blisters do not hurt, try to keep the blisters complete, and the damaged skin on the blisters can provide the human body with a natural bacterial barrier and reduce the risk of infection. If the injury is serious, the hospital must be sent to the hospital immediately. The hospital will treat drugs such as antibiotics and tetanus. If the blister looks infected, he must also seek medical treatment. If you suffer from poor diabetes or poor blood circulation, contact your doctor before handling the blisters by yourself.

However, if the light blisters are lighter, if it is really difficult to bear pain, in order to relieve discomfort, you can choose to discharge the liquid in the blisters, but at the same time, the skin should be kept intact, otherwise the bacteria will invade quickly and infected infections, and infection will also cause infection. Essence So, how to discharge liquids?

Clean your hands and blisters with soap, warm water. Wipe the surface of the blister with iodine. Disintegrate sharp needles with alcohol. For a few points near the edge of the blisters, pierce the blisters with needles to discharge liquids, but leave the covered skin in situ. Apply ointment on the blisters and cover it with non -stick gauze. If a rash occurs, stop using the ointment. Check whether the blisters are infected every day. A few days later, all dead skin was cut off with scissors disinfected with alcohol. Apply ointment and use dressing. The introduction of the blisters is here, and I sincerely remind everyone and the editor ourselves -no matter how properly handling the blisters, it is also uncomfortable. It is better to stay away from hot things, exercise appropriate amounts, and wear appropriate shoes!
