Scalp is the part of human body with richer blood supply, once trauma occurs, the bleeding is usually more, which cannot be compared with the torso and limbs, so it is recommended to bandage and stop bleeding in time. Because the head is a sphere, and limb bandaging, pressure is different, head trauma bandaging methods are specifically as follows: 1, return bandage: after covering the wound with a dressing, wrapped back with a bandage; 2, mesh sleeve: currently usually use the mesh sleeve, propped open, directly on the head, to achieve the purpose of stopping bleeding; 3, triangular towel bandage: its shape is similar to the red scarf, available triangular towel will be wrapped around the head, and then fixed.
