adhesive plaster的意思|示意

Adhesive plaster (also known as a band-aid or sticking plaster) is a patch made of cloth, plastic or metal that is coated with a sticky adhesive substance. It is used to cover and protect minor wounds, such as cuts, scrapes, and blisters, to help them heal.

Adhesive plaster is applied directly to the skin. First, the skin should be washed and dried, then the adhesive patch should be applied. It should be firmly pressed against the skin so that it sticks properly, and edges should be smoothed down to prevent it coming off.

Adhesive plaster should be changed regularly and at least daily, as the sticky surface gradually loses its effectiveness. Special waterproof varieties are available for use in showers and baths.

Adhesive plaster should not be used over deep or large wounds, or over skin that is infected, weeping or very large areas, as it could separate from the skin allowing bacteria to enter the wound. If this happens, the wound should be cleansed and further treatment may be necessary.

Adhesive plaster can also be used to hold dressings in place, or to protect and support limbs that are in a cast. It is also used in sports to protect the skin against friction and to prevent blisters.

Adhesive plaster is an easy to use, convenient and portable product, which has a range of uses where an infection-controlled, temporary covering is required. It is also a fairly inexpensive product, which can be found in most chemists, pharmacies and supermarkets.
