在現場急救中主要使用橡皮止血帶和布性止血帶。 In the first aid, rubber tourniquet and cloth tourniquet are mainly used. 橡皮止血帶是一種特制特制的橡皮管，在現場可使用橡皮條、自行車內胎等替代。使用時要把止血帶放在肢體適當的部位，如上肢要放在上臂中上1/3處;下肢放在大腿的中下1/3處。先在上止血帶的部位墊一層軟布，如毛巾、口罩等以保護皮膚。救助者用左手拇指、食指和中指持止血帶的頭端，右手將橡皮管拉緊繞肢體一圈后壓住頭端，再繞肢體一圈后將右手持的尾端放人左手食指中指之間，由食指中指夾持尾端從兩圈止血帶下拉出一半，使之成為一個活結。如果需要松止血帶時，只要將尾端拉出即可。 The rubber tourniquet is a specially made rubber tube, which can be replaced by rubber strips and bicycle tubes at the scene. When using, should put the tourniquet in the appropriate part of the body, such as the upper arm should be placed on the upper arm 1/3, lower limbs placed in the lower middle of the thigh 1/3. First put a layer of soft cloth on the part of the tourniquet, such as towels, masks and so on, to protect the skin. Rescuers use the left thumb, forefinger and middle finger of the right hand to the head end of the tourniquet, the rubber tube tension around the limb ring pressed the head end, between a circle around the limb after the end of the right hand hold put left index finger, the index finger holding end from two produced a half circle tourniquet that makes it a slipknot. If you need a tourniquet, just pull out the tail. 布性止血帶是用繃帶或布條制成的止血帶?，F場急救時可用毛巾、衣物撕成布條代替繃帶。將布帶纏繞肢體一圈后打結，圈內插入一小木棍絞緊，邊絞邊看出血情況，動脈出血剛剛止住即為松緊適度。然后將小木棍用布條固定。 A cloth tourniquet is a tourniquet made of bandages or strips of cloth. When the first aid is available, towels and clothes can be torn into cloth instead of bandage. The winding limb ring knot, the circle into a small wooden side cutter able to bear, while watching the bleeding, bleeding artery is just stop moderate. Then fix the stick with cloth. 止血帶的使用方法比較簡單，但使用原則較復雜。只有準確地掌握這些原則使用得當，才能起到挽救生命和肢體的作用，否則將導致截肢致殘。 The use of tourniquet is simple, but the principle of use is complicated. Only by accurately mastering these principles and using them properly can they save lives and limb, or they will cause amputation and disability. 1.上止血帶前，應先將傷肢抬高，促使其中靜脈血液流回體內，從而減少血液丟失。 1. before the tourniquet, the injured limb should be elevated, prompting the venous blood to flow back into the body, thereby reducing blood loss. 2.上止血帶的位置應在有效止血的前提下，盡量靠近出血部位。但在上臂中段禁止使用止血帶，因為該處有橈神經從肱骨表面通過，止血帶的壓迫可造成橈神經損傷，進而使前臂以下的功能日后難以恢復。 2. the location of the tourniquet should be close to the bleeding site as much as possible under the condition of effective hemostasis. But in the mid upper arm to prohibit the use of a tourniquet, due to the radial nerve in the distal surface by tourniquet compression can cause injury of the radial nerve, and the forearm function below the day after it is difficult to restore. 3.止血帶不能直接綁在肢體上，準備上止血帶的部位應先墊一層敷料、毛巾等柔軟的布墊，用以保護皮膚。 3., the tourniquet can not be directly tied to the body, the preparation of the tourniquet should be padded with a layer of cloth, towels and other soft cloth pad, used to protect the skin. 4.用毛巾、大手帕等現場制作的布性止血帶時，應先將其疊成長條狀，寬約5厘米，以便受力均勻。嚴禁使用電線、鐵絲、細繩等過細而且無彈性物品充作止血帶，因為這些物品不僅止血效果不理想而且還損傷皮膚，為日后的治療和康復帶來麻煩。 4., with towels, large handkerchief and other on-site production of cloth tourniquet, it should be folded into strips, width of about 5 cm, so as to force evenly. Prohibited the use of wire, wire, etc. and non elastic articles or string as a tourniquet, because these items not only hemostatic effect is not ideal, but also damage the skin and cause trouble for treatment and rehabilitation after the day. 5.綁止血帶時其松緊度以剛壓住動脈出血為宜。上帶過緊易造成止血帶處的皮膚、神經、血管和肌肉的損傷，甚至引起肢體遠端的壞死，不利于今后傷肢的功能恢復;上帶過松只壓住靜脈未壓住動脈，血液只出不進，不僅達不到止血目的反而加重出血。上帶成功的標準是，遠端動脈性出血停止、動脈搏動消失、肢端變白。 5. when tying a tourniquet, the tightness of the tourniquet is just as pressing as the bleeding of the artery. With easy to cause the skin tight tourniquet, nerves, blood vessels and muscle damage, and even cause the distal limb necrosis, is not conducive to the future of the injured limb function recovery; on the belt is too loose on the vein is not only on the artery, blood not only, can not achieve the purpose of hemostasis aggravate bleeding. The criteria for success in the band were distal arterial bleeding, arterial pulsation, and acral white hair.
