Wilderness activities, full of excitement and challenges, but also unlimited possibilities . If you encounter a physical hazard, call 120 for help if the physical hazard affects subsequent limb movement. Do yourself as much as possible with self-help behaviors that are good and can be improved.
For example, if you are bitten by a snake outdoors, make sure to drain the blood from the wound in a timely manner. Because people who don't see snakes very often aren't able to tell say if there is a toxin or not; it's a very dangerous behavior.
Previously, someone was bitten by a snake, and then sent it to a friend; coincidentally, there was just one snake expert who knew about this highly venomous snake. Then he contacted the person who sent the circle of friends and gave timely guidance and rescue to the injured person, and eventually rescued the person from danger.
Outdoors, if you have a limb injury that causes you to have difficulty moving, you need to find the nearest place where you can avoid risk, avoid the wind and rain, and wait for the rescue to come to your aid. (For injuries: sprains, falls, etc., do not make large movements or massage yourself and wait for help.)
If it is a limb stabbing or cutting, use the warm water or saline you carry to rinse and wipe the wound, to avoid bacterial infection. For small wounds, simple treatment can be done with a band-aid or simple gauze first. Depending on the severity of the wound, you may choose to repair it yourself or seek medical attention. (Try to squeeze out as much blood as possible from small wounds to avoid contact with bacteria and dirt. Simply clean the wound and dress it with a clean cloth.)
It's basic common sense for people who spend a lot of time outdoors to carry simple medical supplies with them. People who do not have ambulance supplies must make timely preventive measures to prevent the possibility of deepening the condition.
