Blister bandages hydrocolloid
Blister bandages hydrocolloid is an oval dressing that contains a gel-forming agent in an adhesive compound laminated on a flexible, water-resistant outer layer. Some formulations contain alginate to increase absorption capacity. Wafers are self-adhesive, can be provided with or without adhesive frames, and have various thicknesses and pre-cut shapes, can be used for body bones, elbows and heels and other body parts
A hydrocolloid bandage is a flexible bandage made of water-absorbing material attached to a plastic film. The bandage adheres to the open wound with the absorbent film facing down. Hydrocolloids were originally designed for ulcers, but they are becoming more and more popular in acne, especially in Asia.
The tough outer plastic film is usually polyurethane, which can hold everything in place and prevent the evaporation of water and dry the wound, so the wound heals faster and the new skin formed is soft rather than tight and stiff. It also protects the wound from rubbing and scratching.
Water-absorbing materials are usually made of carboxymethyl cellulose, gelatin and/or pectin, and they have many water-binding groups in their chemical structure. This sucks fluid out of the wound. When the liquid enters the bandage, it will change from transparent to white and swell, which means you will get very satisfactory white spots
Blister plaster on popped blister are closed, so they provide:
• Moist rehabilitation environment
• Autolysis debridement
Benefits of hydrocolloid dressings • Impermeability of bacteria and other contaminants
- Self-adhesive and mildew-proof (do not stick to the wound, only to the complete skin around the wound)
- Can be used for intravenous compression products
- Easy to apply
- Minimal disruption of healing
