Why do I pick up my bag after a headbang? Why is it easy to pick up the bag when the head is hit?

Many children have encountered this phenomenon. accidentally hit his head on the hard gate, and although it didn't break, he immediately got up a big bag. This is because there is not much muscle and fat in the head, and when a hard object touches the soft tissue under the skin, it is injured, and the blood plasma oozes out and collects between the scalp and the skull, forming a lump.

The capillaries under the scalp have been injured and ruptured, and blood is oozing from the injured area. Since there is very little muscle and fat under the scalp, the blood oozing from the blood vessels cannot be diffused, and it accumulates between the scalp and bones in the injured area, so a large lump bulges. It is easy to get up after a head bump because there is very little muscle and fat on the head, and when the head hits a hard object, the subcutaneous tissue is damaged.

Blood, especially plasma, oozes out and collects between the scalp and the skull, forming a lump. But in some soft parts of people's thighs, abdomen, etc.

Muscles have a lot of fat, and oozing blood and plasma can diffuse under the skin, so only bruising patches can form, not cuffs. This is because there are many small blood vessels underneath, and when a person is collided, although the capillaries are not broken, the capillaries are ruptured, and the blood slowly flows out of the damaged capillaries and gathers underneath. It looks like it's green and purple.

But it doesn't matter, after a few days, the blood will be slowly absorbed, and the blue and purple on the ** will disappear.

The inflammatory reaction will occur in the area of the bruise, that is, congestion and edema, and the subcutaneous tissue of the head is relatively dense, and when the congestion and edema are severe, it will appear harder. After being hit, after the small blood vessel wall under ** ruptures, ** swells up, and after a few days the blood is absorbed, the blood lump slowly disappears, and ** is not swollen.

Because although there is no bleeding at the hit site, the cells have been injured, and the injured cells will produce some fluid, which will spread for a while, and will gather between ** and the skull to form a large bag.

Many children accidentally hit their heads when they were playing, and they would soon be discovered by their parents, because the place where they were hit quickly swollen with a big bag, and this big bag came from **?

It turned out that although there was no bleeding at the hit site, the cells had been injured, and the injured cells would produce some fluid, which would have nowhere to spread for a while, and would have gathered between ** and the skull.

So, why don't other parts of the body generally appear in large bags?

This is because the subcutaneous fat of the head is usually relatively thin and does not have enough fat layer, and relatively speaking, the subcutaneous fat in other parts of the body is thicker, and there is muscle tissue as a buffer, even if these places are bumped and produce bruising, they can also flow to **, fat, muscle, at most bruises, but generally do not produce a large bag, and for the scalp, the lower layer is the skull, once the bruising occurs, it can only bulge outward, so it is easy to see a big bag.

Usually, the head is knocked out of a big bag does not need **, basically after a period of time will gradually disappear, but do not use your hands to rub, do not immediately warm compress, otherwise this hematoma will become more and more serious, for smaller hematomas, in the first two days after the injury, wrap ice cubes with a towel or use ice packs for local cold compresses to help stop bleeding; On the 3rd day, a warm compress is applied to promote the absorption of the hematoma, which can be completely absorbed within 1 to 2 weeks.

<>1. This is because there is less fat in the head, and there are capillaries under the skin. When subjected to an external impact, the capillaries rupture. And because there is no fat, it overflows under the skin, and a large bag appears at the loss of the beam.

2. At this time, you must not knead it, and do not use hot water to compress it. Zhengqin's method is to use cold water to cool the compress. After 24 hours, use hot water again.

This facilitates the recovery of capillaries. It is the principle of thermal expansion and cold contraction. It will be gone in a few days.

Let's start by explaining the ingredients of this pack.

Infants and young children are mostly passively impacted, such as the forehead touching the adult's teeth and the head of the sedan chair when playing; I fell out of bed while I was sleeping, and I touched it; The adults didn't hold it well, bumped into or fell somewhere. Generally, in the case of light, apply some cooking oil, pediatric pp cream, and scattered stasis cream after two days.

If the mass is a little large, it can be used immediately with a cold compress to stop the bleeding, and it must not be rubbed to aggravate the rupture of the capillaries. After a cold compress for a while, the lump no longer becomes larger, and then apply the ointment for children to disperse stasis, and then apply a hot compress to disperse stasis after a day.

If the mass is also accompanied by bleeding problems, then you have to find a doctor to deal with it, and you should not bandage it at will to cause trauma ** dyeing and inflammation.

If the back of the head hits the ground and a big bag is raised, you have to observe that it is subcutaneous bruising? Soft tissue injuries? Under normal circumstances, the child will cry fiercely and has no abnormal reaction, so it can be treated according to the method of cold compress first, then apply medicine, and then hot compress.

If the child's behavior is abnormal, such as convulsions, vomiting, lethargy and other symptoms, he must be sent to the hospital immediately for emergency treatment to rule out brain ** and intracranial problems! Try to soothe your child and avoid agitation.

The adult's head hit the big bag, and the external force must have been very strong. If there is no rupture, the lump is not very large, you can use ice cubes to gently press the cold compress, and the pain and swelling will be reduced after ten minutes. In the later stage, you can apply some safflower oil or loose stasis ointment, take three seven tablets orally, and then apply a hot compress to disperse stasis after ten hours, or you can use a hot compress with boiled eggs.

If the mass is very congested, you have to go to the hospital to draw out the blood and do the corresponding ** treatment; If you have dizziness, vomiting, lethargy, or convulsions, you should go to the hospital immediately to check for brain damage and other problems caused by the impact.

Some people often hit their heads with sails, and after the impact, they also deal with it themselves or endure the pain. These people think that their heads are all bones that can't be broken. However, the brain in the skull is a soft tissue, and the cranial nerve is very fragile.

The head hit a big bag, and the bag disappeared soon after, but the vision gradually blurred, and often accompanied by tinnitus, and it was found that the intracranial congestion compressed the optic nerve and auditory nerve.

This is because after the violent impact, the subcutaneous tissue has been severely impacted, and the cells are damaged, and after the cells are damaged, a series of fluids will be produced, which cannot be penetrated from the ** and have nowhere to spread, and will inevitably gather at the bottom of the ** to form a large bag.

Because after slamming the head, the interstitial fluid inside will be squeezed, and if the interstitial fluid increases, the cells will become larger, and there will be a large bag.

This is because the blood circulation is poor after hitting the head. Then it will pile up and it will form a big bag.
