Description

Technical Field

[0002] Band-Aid is the most commonly used surgical medicine in people's lives. It is usually a long adhesive tape with gauze soaked in medicine in the middle. It is used to stick on the wound to protect the wound, temporarily stop bleeding, resist bacterial regeneration, and prevent the wound from being damaged again. It is the most commonly used first aid essential medical supply in hospitals, clinics, and homes; however, the length of ordinary band-aids on the market is fixed and cannot be adjusted according to the location of the wound. When using a band-aid, a shorter band-aid is required on smaller joints such as fingers. The long length of the band-aid will make it inconvenient to stick it; a longer band-aid is required on larger joints such as the knee. The short length of the band-aid will cause the band-aid to fall off easily when the knee is bent due to the greater force.
