Yesterday, I accidentally hurt my hand when I used the silk wiper. My mother quickly brought me a medicine box to sterilize and put a band-aid, but when my mother saw that the blue one was useless, she changed it. At that time, I was curious. I looked at it. One was a band-aid and the other was a band-aid, and the color was different. Today I looked it up online. Oh! It turns out that their functions are different. Let me tell you about their differences!

Band-aid is used to stick on the wound, which can resist bacterial regeneration and prevent the secondary injury of the wound. Band-aid is breathable. Its purpose is to protect the wound from infection caused by foreign bodies, stolen goods and bacteria in a short time. It is not an "ointment" for healing wounds, and it does not play a decisive role in wound healing (except Yunnan Baiyao Band-aid). It cannot always play a role in preventing infection in a long time.

band-aid? It's something for simple treatment after minor trauma. Band-aid is one of the most commonly used surgical drugs in people's lives. Band-aid, also known as "hemostatic plaster", has the functions of stopping bleeding and protecting creation. It is composed of a long adhesive tape with a small piece of gauze soaked in medicine in the middle. Due to the limitation of its structure, the band-aid can only be used for emergency treatment of small wounds, so as to temporarily stop bleeding and protect the wound surface. However, it should be noted that it should not be used for too long. If you use it for too long, the adhesive tape on the outer layer of the band-aid is airtight. It will make the skin around the wound white and soft, leading to secondary infection of bacteria. This will make the wound worse. But please note that once it is soaked, it must be replaced, otherwise bacteria will easily enter the wound and make it worse.

The most obvious difference between them is that the band-aid is breathable, but the band-aid is airtight. Do you understand?
