说到医用止血带，顾名思义，这是一款专门用于止血的产品，一般来说，需要使用医用止血带的只有两个部位，一个是前臂（就是腋下），还有一个就是大腿的上部。
Speaking of medical tourniquet, as its name implies, it is a product specially used for hemostasis. Generally speaking, there are only two parts that need to use medical tourniquet, one is the forearm (that is, the armpit), and the other is the upper thigh.
在必须要使用到止血带，又没有专业的止血带时，要选择宽度至少为5厘米的布带，如果附近只有很窄的线或者是绳索，必须要垫上折叠多层的布料，避免伤处不适，从而损伤神经或者是肌肉。
When the tourniquet must be used and there is no professional tourniquet, you should choose a cloth belt with a width of at least 5 centimeters. If there is only a very narrow line or rope nearby, you must pad with folded multi-layer cloth to avoid discomfort of the wound, thereby damaging nerves or muscles.
止血时要先用止血带沿着肢体捆绕三圈，系成一个半结，然后在结上放一根轻便的短棍，再把它捆成双结，使用时要把止血带捆的足够紧，阻止血液供应，但是在这期间，必须要间歇性松开。
The tourniquet should be tied three times along the limbs to form a half knot, then put a light stick on the knot, and then tie it into a double knot. The tourniquet should be tightened enough to prevent blood supply, but during this period, it must be loosened intermittently.
