Thin Type Hydrocolloid Wound Dressing

What is a Hydrocolloid dressing?

Hydrocolloid dressing is an innovative medical dressing designed based on the principle of moist healing. It is widely used in the care of chronic wounds, burns, postoperative wounds and other scenarios. Its core features and composition as follows:
1. Materials and structure
Composite material: It is made of elastic polymer hydrogel (such as sodium carboxymethyl cellulose) mixed with synthetic rubber, medical adhesives, etc. to form a viscose sheet structure.
Layered design: It usually includes a semipermeable membrane surface layer (allowing oxygen and water vapor exchange and blocking foreign matter from the outside) and a gel core layer (forming a hydrophilic gel after contact with exudate).
2. Mechanism of action
Exudate management
After absorbing exudate, it expands to form a gel (can expand up to 12 times), dynamically adjusts the absorption capacity, and avoids wound immersion.
The semipermeable membrane surface promotes water evaporation and prevents exudate accumulation.
Promote healing
Maintain a moist and closed environment, stimulate microangiogenesis and epithelial cell migration, and accelerate the healing rate.
By activating macrophages and endogenous enzymes to dissolve necrotic tissue, painless autolytic debridement is achieved.
‌Protection function‌
The adhesive material adheres closely to the skin, forming a physical barrier and reducing the risk of bacterial infection.
The smooth outer surface reduces friction and prevents pressure sores and secondary injuries.
