The method of using quick release buckle tourniquet is relatively simple, but the principle of use is more complicated. Only by accurately mastering these principles and using them properly can they save lives and limbs, otherwise it will lead to amputation and disability. What is a quick release buckle tourniquet? How to use ick release buckle tourniquet?

This passage is going to talk about the following questions of quick release buckle tourniquet:

(1) What is quick release buckle tourniquet?

(2) How to use quick release buckle tourniquet?

(3) Attentions

(1) What is quick release buckle tourniquet?

Quick release buckle tourniquet. The characteristic of this tourniquet is a solid plastic buckle with a plastic buckle, which can be quickly released by touching it with a finger. This hemostatic buckle uses a fixed vein to control blood flow during blood collection or injury.

(2) How to use quick release buckle tourniquet?

The use of tourniquets is relatively simple, but the principles of use are more complicated. Only by accurately mastering these principles and using them properly can they save lives and limbs, otherwise it will lead to amputation and disability.

1. Before applying quick release buckle tourniquet, the injured limb should be raised to encourage blood from the veins to flow back into the body, thereby reducing blood loss.

2. The position of the upper tourniquet should be as close as possible to the bleeding site under the premise of effective hemostasis. However, it is prohibited to use a tourniquet in the middle of the upper arm because the radial nerve passes through the surface of the humerus. The compression of quick release buckle tourniquet can cause damage to the radial nerve and make it difficult to restore the function below the forearm.

3. Quick release buckle tourniquet cannot be tied directly to the limbs. The part where quick release buckle tourniquet is prepared should be covered with a soft cloth pad such as dressing and towel to protect the skin.

4. When using a cloth tourniquet made on-site with towels, bandannas, etc., it should be folded into a strip with a width of about 5 cm so that the force is even. It is strictly forbidden to use wires, iron wires, string and other thin and inelastic items as tourniquets, because these items not only have unsatisfactory hemostatic effects, but also damage the skin, which will cause trouble for future treatment and rehabilitation.

(3) Attentions

When tying quick release buckle tourniquet, its tightness is appropriate to just compress the arterial bleeding. Too tight the upper band can easily cause damage to the skin, nerves, blood vessels and muscles at quick release buckle tourniquet, and even cause necrosis of the distal limb, which is not conducive to the functional recovery of the injured limb in the future; too loose the upper band only compresses the veins but not the arteries. Blood can only go out and not in, which not only fails to achieve the purpose of hemostasis, but worsens the bleeding. The criterion for the success of the upper band is that the distal arterial bleeding stops, the arterial pulsation disappears, and the extremities turn white.

The wounded on quick release buckle tourniquet should be clearly marked, and the time of the tour should be clearly written near quick release buckle tourniquet or on the skin. In order to prevent ischemic necrosis of the injured limb, relax quick release buckle tourniquet for 1 to 2 minutes every 40 to 60 minutes, move slowly when loosening the band, and need to press the wound to reduce bleeding. If the general condition of the wounded is poor, the wound is large, and the amount of bleeding is heavy, the time interval for relaxing quick release buckle tourniquet can be appropriately extended. However, the total time of using quick release buckle tourniquet cannot exceed 3 hours, otherwise the distal limbs will not survive. If the wounded is still on the way to the hospital for more than 9 hours, quick release buckle tourniquet will not be loosened regularly thereafter, because the distal limbs are no longer likely to survive. Necrotic cells release toxic substances such as potassium ions, myoglobin, and peptides. If the limbs are loosened at this time, these toxic substances will flow into the body through the veins, causing poisoning, which can lead to cardiac arrest and sudden death. In the same way, in the earthquake-stricken area, if the injured limbs are buried for too long, tissue necrosis has occurred due to ischemia and hypoxia. To prevent toxins from returning to the whole body, the compressed limbs should be ligated quickly with a tourniquet. Then remove the crushed object, and then send it to the hospital for further treatment.
