What should I do if my fingers hurt and bleed?

Fingers bleed first, hold it down to stop the blood from flowing, and then disinfect it with iodophor disinfectant. If it still bleeds, press it with disinfectant until the bleeding finger stops bleeding for a minute or two, sprinkle with hemostatic powder and wrap it with a band-aid. As long as it touches water, it must be disinfected to prevent wound infection. The main wound should be ventilated and healed quickly. If the wound can't stop bleeding, you should go to the hospital immediately!
