Types of plaster
Also called a sticking plaster Is a small dressing used for injuries not
serious enough to require a full-size bandage.
Adhesive plasters
The adhesive bandage protects the cut from friction, bacteria, damage, or dirt.
Thus, the healing process of the body is less disturbed.
Sometimes they have antiseptic properties. An additional function is to hold the two cut
ends of the skin together to make the healing process faster.
Function
An adhesive bandage is usually covered by woven fabric, plastic, or latex rubber which has an adhesive.
Adhesive bandages usually have an absorbent pad, which is sometimes medicated with an antiseptic solution.
Material
Some bandages have a thin, porous-polymer coating over the pad to keep it from sticking to the wound.
The bandage is applied such that the pad covers the wound, and the fabric or plastic sticks to the surrounding skin to hold the dressing in place and prevent dirt from entering the wound.
