Rubber tourniquets and cloth tourniquets are mainly used in on-site first aid.
The rubber tourniquet is a special rubber tube that can be replaced with a rubber strip or a bicycle inner tube at the site. When using, place the tourniquet in the appropriate part of the limb. The upper limb should be placed in the upper third of the upper arm; the lower limb should be placed in the lower third of the thigh. First place a soft cloth, such as a towel or a mask, on the upper tourniquet to protect the skin. The rescuer holds the head end of the tourniquet with the left thumb, forefinger and middle finger. The right hand pulls the rubber tube around the limb and presses the head end. After the circle around the limb, the right end of the hand is placed on the middle finger of the index finger. During the interval, the middle finger of the index finger clamps the tail end and pulls out half of the two tourniquets to make it a slip knot. If you need to loosen the blood strip, just pull the end out.
A cloth tourniquet is a tourniquet made of bandages or cloth strips. Towels and clothing can be torn into strips instead of bandages during first aid. After the cloth is wrapped around the limb, the knot is knotted, and a small wooden stick is inserted into the loop to tighten the wound. The bleeding is observed while the arterial bleeding just stops. Then fix the small wooden stick with a cloth strip.
The use of tourniquets is relatively simple, but the principles of use are more complicated. Only by accurately mastering these principles can they save lives and limbs, or they will lead to amputation and disability.
