In real life, if the epidermis is only slightly scratched, or some small and shallow wounds, especially the cut wounds with neat and clean incision and little bleeding without suture, it can prevent infection by scrubbing and smearing the wounds with iodine or ethanol. But if you are not at ease, you can apply a thin layer of purple medicine to the wound.
But after two or three days, it will almost scab. If the skin wound is deeply injured and there is no condition to deal with it at that time, you can rinse the wound with clear water and then simply wrap it with a band-aid. However, it must be noted that the band-aid should not be used for too long. Try to change it every day, usually no more than two days.
Band-AIDS are not suitable for large and deep wounds with foreign bodies. After simple treatment at the scene, you should go to the hospital for regular disinfection immediately to avoid serious infection. If the wound has been contaminated or infected, or there are various skin diseases, it is not suitable to use a band-aid.

Misunderstanding of use and matters needing attention
1, band-aid is a panacea
Band-aid is not a panacea, and it is not suitable for all wounds. Generally speaking, Band-Aids are mainly used for some small and shallow wounds, especially those with neat and clean incisions and less bleeding, such as knife wounds, cuts and glass scratches.
The correct way: we must strictly control the indications. Band-AIDS should not be used for large and deep wounds with foreign bodies. In this case, you should go to the hospital in time. Used for contaminated or infected wounds, such as severe skin abrasions and burns. It is not appropriate to use a band-aid. For folliculitis, furuncle, suppurative infected wounds and various skin diseases, it is even more inappropriate to use band-AIDS.
For wounds caused by animals such as dog bites, cat scratches, snake bites, poisonous insect bites or bites, it is forbidden to use band-aid to avoid the accumulation or spread of poisons and germs in the wounds. In the first time, rinse the wound repeatedly with clean water, herbal tea, mineral water, physiological saline and 2% soapy water 15 minutes or more.
2. Band-AIDS can be pasted casually
When you use a band-aid, you always stick something casually for convenience, which is not correct.
The correct way: before using the band-aid, check the wound for dirt residue. If there are impurities, be sure to clean the wound with sterile saline before sticking the band-aid.
If the wound is pierced and deep by nails and other things, you should go to the hospital immediately and need to inject tetanus antitoxin. Secondly, after opening the band-aid, avoid polluting the medicine surface. When smearing, the medicine surface must be aimed at the wound, and the two sides of the wound should be slightly pressurized after smearing.
3. Band-AIDS can be stuck for a long time
Putting a band-aid on a wound doesn't mean that everything is fine, and it can't be left alone for a long time.
The correct way: First, pay attention to the changes in the wound. If the band-aid feels "pulsating pain" similar to pulse beating after 24 hours of use, or secretion overflows, it should be opened in time to observe whether there is redness, swelling and heat pain around the wound. If there is, it means that the wound has been infected and you should seek medical treatment immediately.
The second is to pay attention to protecting the wound. After the band-aid is used, don't always pinch the wound with your hands, and the local part of the wound should move as little as possible to prevent collision and crack. Third, the band-aid should not be used for too long, otherwise it will breed bacteria and should be replaced every day.
