Introduction

Water colloid dressing is based on the wound wet healing theory based on the new dressing, by the water-soluble polymer particles (such as carboxymethyl fiber Pectin, etc.) and rubber sticky material mixed processing, with the outer substrate. Water-soluble polymer particles absorb the wound exudate after swelling into Hydrogel-like, can maintain a wet wound environment. Applicable to superficial wound, a small amount to the amount of exudate wound and for the skin area.

Water colloidal dressings are currently widely used for radiation sterilization.
