The correct way to apply a Band-Aid

The correct way to apply a Band-Aid is to disinfect it first and then apply it to the wound.

A Band-Aid is a long piece of adhesive tape with medicated gauze in the middle. It can be applied to the wound to protect the wound and temporarily stop bleeding. It can also resist bacterial regeneration and prevent the wound from being damaged again. Before using a Band-Aid, you need to disinfect the wound with iodine or alcohol, which can effectively avoid symptoms of bacterial infection. After disinfection, tear off the Band-Aid and stick it to the wound. When using Band-Aids, you should observe whether the local skin shows any allergic symptoms. If allergic symptoms occur, such as itching or redness, you should not use Band-Aids, otherwise it will affect normal wound healing.

Band-Aids should not be used for too long. Usually they need to be changed every 8 to 12 hours. If they are used for too long, it will affect the normal healing of the wound. After using the Band-Aid for a period of time, if the wound still shows symptoms of exudation or bleeding, it means that the wound is relatively large and you need to go to the hospital for clearance as soon as possible. If necessary, sutures are needed to promote wound healing. Keep the wound clean during the recovery process.
