The Introduction Of Band Aid Leave a comment

Adhesive bandages protect wounds and scars from friction, bacteria, damage and dirt. Therefore, the body’s healing process is less subject to interference. Some dressings have anti-corrosion properties. Another function is to hold the two cut ends of the skin together to make the healing process faster.

Adhesive bandages are small sheets of flexible material that are viscous on one side and have a small, non-tacky absorbent pad on the viscous side. Place the pad on the wound to smooth the overlapping edges of the viscous material so they stick to the surrounding skin. The adhesive bandage is typically packaged in a sealed sterile bag with the backing covering the adhesive side; the backing is removed when the bandage is applied. They come in a variety of sizes and shapes.

Hydrogel dressing. Fully transparent adhesive bandage with clear hydrogel pad and viscous waterproof plastic film (removable backing in blue and white).
Backings and bags are usually made of coated paper, but can also be made of plastic.

The adhesive sheet is usually a fabric, a plastic (PVC, polyethylene or polyurethane) or a latex strip. It may or may not be waterproof; if it is airtight, the strap is a closed dressing. The binder is typically an acrylate, including methacrylate and epoxy diacrylate (also known as vinyl).

The absorbent pad is typically made of cotton and sometimes has a thin porous polymer coating on the pad to prevent it from sticking to the wound. The pad can also be dosed with an antibacterial solution. In some bandages, the pad is made of a water-absorbent hydrogel. This is especially common in dressings for blisters because the gel acts as a buffer. [requires medical reference]

Many people are allergic to these materials, especially latex and some adhesives.

The wound is closed and the butterfly is closed.
Food preparation workers use special bandages. These are waterproof and have strong adhesives, so they are less likely to fall off and are usually blue so they are more clearly visible in the food. Some include metal strips that can be detected by machines used in food manufacturing to ensure that the food is free of foreign matter.

A transdermal patch is an adhesive bandage that has the function of dispensing a drug through the skin rather than protecting the wound.

Butterfly closures, also known as butterfly seams, are usually thin adhesive strips that can be used to close small wounds. They pass through the laceration in a way that pulls the skin on either side of the wound together. They are not true sutures, but can often be used in addition to or in place of real sutures for small wounds. Butterfly stitching can be advantageous because they do not require a medical professional to place or remove and are therefore common items in a first aid kit.
