Data: 2022-05-05
Disposable tourniquetMainly used for first aid,Hemostasis for single useThe use of the belt is very simple, but the principle of use is very complicated. Only by accurately grasping these principles and applying them correctly can lives and limbs be saved, otherwise it will lead to amputation and disability. Below. let's say, the use of disposable tourniquet method.
1. onDisposable tourniquetBefore, the injured limb should be raised first to encourage them to flow back into the body, including venous blood, so as to reduce the blood loss of the patient.The tourniquet should be placed in the appropriate part of the limb, such as the 1/3 of the upper arm, the 1/3 of the lower leg. Put a soft cloth, such as a towel or mask, on the tourniquet to protect the skin.
2.Under the premise of effective hemostasis, the position of the upper tourniquet should be as close as possible to the bleeding site. However, the use of a tourniquet is prohibited in the middle part of the upper arm because the radial nerve passes through the surface of the humerus,And the compression of the tourniquet can cause radial nerve damage, which makes it difficult to restore function below the forearm in the future.
3. Disposable tourniquetIt must not be attached directly to the limb, and the part to be attached to the tourniquet should be covered with a soft cloth, such as a dressing or towel, to protect the skin.
4.When making cloth tourniquets on site, such as towels and bandages, the tourniquets should be folded into long strips with a width of about5Centimeters, in order to evenly force.It is strictly forbidden to use thin and inelastic items such as steel wire, steel wire, and steel wire rope as tourniquets, because these items not only have a poor hemostatic effect, but also damage the skin and cause trouble for future treatment and rehabilitation.
5.When the disposable tourniquet is tied, it should be tight just enough to press against the arterial bleeding.Tight tourniquet easily damage the skin, nerves, blood vessels and muscles, and even cause distal limb necrosis, is not conducive to future recovery of limb function;The upper bandage only presses the vein without pressing the artery, and the blood can only enter and exit, which not only cannot stop bleeding, but also aggravates bleeding.The criteria for successful bandaging were cessation of distal arterial bleeding, disappearance of arterial pulsations, and whitening of the limbs.
6The wounded who use the tourniquet once should have a clear and important sign, and write the time on the tourniquet near or on the skin.To prevent ischemic necrosis of the injured limb, every40～60Minute relaxation tourniquet 1～2Minutes, move slowly when loosening the band..At the same time we need to use finger pressure wounds to reduce bleeding in patients.However, the total time management for the use of disposable tourniquets cannot exceed3hours, otherwise distal limb activity is difficult to improve survival.
