Treatment: A, mild abrasion: If the wound is clean, it can heal itself by applying purple medicine. B, severe abrasions: First of all, stop bleeding, which can be stopped by cold compress, raising limbs, bandage pressure dressing, finger direct pressure and other methods.

2, nosebleeds (nose bleeding caused by external impact)

Treatment: The injured person should sit down, raise his head back, breathe through his mouth temporarily, plug his nostrils with gauze, and apply cold towels on his forehead and bridge of his nose to stop bleeding.

3, sprain (when the range of motion of the joint exceeds the normal limit, the ligament, tendon and muscle surface attached around the joint are torn)

Treatment of severe sprain: stop bleeding and relieve pain first. You can lift the injured limb, wash the injured part with cold water or apply a cold towel to make the blood vessels contract and reduce the degree of bleeding and pain. Don't rub around to prevent bleeding from increasing. Then apply cotton to the wound and bandage it under pressure. After 48 hours of injury, use hot compress to promote the absorption of congestion.

4. Contusion (subcutaneous tissue, muscles, ligaments or other tissues are injured under the direct action of blunt objects or external forces, and the skin of the injured part is often intact or only slightly damaged)

Treatment: it can be the same as the treatment of sprain.

5. Concussion (excessive vibration of brain nerve cells and fibers caused by external force impact on the head or collision with hard objects)

It is divided into mild, moderate and severe concussion.

Treatment: For patients with mild concussion, after a quiet bed rest for a day or two, they can participate in appropriate activities one week later. For moderate and severe concussion, keep the wounded absolutely quiet, lie flat, apply cold compress to the head, keep warm, and send them to the hospital for treatment in time.

6. Dislocation (the articular surface is out of normal position due to direct or indirect force)

Handling: the movement should be light, and stretching and twisting are not allowed. You can apply cold compress first, put a bandage on it, keep the joint fixed, and then ask the doctor to correct it.

7. rupture

Treatment: first of all, we should prevent shock, keep warm, stop bleeding and relieve pain, then bind up and fix it and send it to hospital for treatment. Kong Xiangting, No.16 Middle School, Zaozhuang City, Shandong Province (Source: China Sports News)
