春季是毒蛇、蝎子、蜈蚣等蛇虫十分活跃的季节，野外郊游一旦被蛇虫咬伤，应及时采取自救措施。首先，不要惊慌乱跑，剧烈活动会使血液循环加快，加速人体对毒素的吸收，加重中毒症状;随后要迅速用止血带或细绳在距伤口5~10厘米处捆扎，阻止毒素在体内扩散，再吸出毒液，用清水或茶水冲洗伤口，并迅速送到医院抢救。家里或是野外出游，常备一次性止血带还是很有必要的。
Spring is a very active season for vipers, scorpions, centipedes and other snakes and insects. In case of being bitten by snakes and insects in field outings, self rescue measures should be taken in time. First of all, don't panic and run around. Strenuous activities will speed up blood circulation, accelerate the absorption of toxins by human body, and aggravate the poisoning symptoms. Then, use tourniquet or string to tie the wound at a distance of 5-10 cm to prevent the spread of toxins in the body, suck out the venom, wash the wound with water or tea, and send it to the hospital for rescue. It is necessary to have a disposable tourniquet at home or in the wild.

In a word, in normal work and life, if there is bleeding from limb injury, we can judge and deal with it according to the specific situation. If the bleeding volume is not very large, we should first choose compression hemostasis, and tourniquet is only a standby treatment method; in case of more serious situation, we should also go to the hospital in time for professional treatment by medical staff to avoid greater injury caused by delayed illness
