There are many types of band-aids on the market. The original intention of band-aids is to suppress bleeding and only apply to small wounds. With the development and innovation of technology, there have been cartoon type band-aids, transparent waterproof band-aids, and large band-aids (for larger wounds).
Band-aids are not suitable for all wounds. Generally, bandages are mainly used for small and shallow wounds, especially for cuts that have neat, clean incisions, few bleeding, and do not require suturing, such as knife cuts, cuts, and glass scratches. For large, deep, and foreign body wounds, it is not advisable to use a bandage. In this case, it is necessary to seek medical attention in a timely manner. For contaminated or infected wounds, such as severe skin abrasions, it is not appropriate to use a bandage. Wounds with boils, suppurative infections, and various skin diseases should not be treated with bandages.
