You should pay attention to the following points when dealing with self-rescue: ?

1. First, stop the bleeding quickly. Use your healthy hand to pinch both sides of the base of the injured finger. After a few minutes, the injured finger will automatically heal. Stop the bleeding. ?

2. To clean the wound, rinse it with cold boiled water or directly under tap water. For wounds with sludge and dirt, use cotton or sponge dipped in soapy liquid to wash away the dirt. ?

3. For small and shallow wounds, you can apply some red liquid or put a "band-aid" on the wound. If the wound still oozes blood, apply Yunnan Baiyao, cuttlefish bone powder, etc. externally, and then wrap it with clean gauze or handkerchief. If the above conditions are not available, you can peel off the bark of the tree strips around you and wrap the wound with bark, which can stop bleeding and prevent infection. ?

4. Try to keep the wound clean and dry within 1 week after the injury. To prevent infection, wash your hands after doing work or housework, and apply iodine to the wound to disinfect it.
