HeraDerm
Wound Dressing Hydrogel(Sterile)

HeraDerm wound dressing hydrogel is a ultra-absorbent, elastic, waterproof, gas-permeable and ultra-thin dressing. The dressing provides the wound in optimal moisture condition, speeds up the wound healing and prevents the scar formation.

⊕Soothe Wound Pain

Neuron cells generate more pain signals because of being dehydrated in a dry healing environment. The exposed peripheral neuron cells sustain in a moist healing environment generate less pain signals so that patients feel more comfortable during healing process.(Ref:Ostomy/Wound Management 2003:49(4A Suppl):2-15)

Hydro-Balance Technology

A+Gel can absorb excess exudates from wound bed rapidly and disperse the exudates within the hydrogel through Hydro-balance Technology.This technology can minimize maceration and pain during dressing change.

⊕SMART dressing-Hydro-balance

For macerating wound
Hydrogel absorbs excess exudate and distributes uniformly within the gel through T-shape dispersion and keeps exudate within the gel to minimize the risk of wound maceration.

For dried wound
Hydrogel maintains wound in moderate moist condition to improve granulation and epithelization.

For skin around wound
Hydrogel keeps the intact skin around wound away from maceration.

⊕Prevent bacteria invasion

Recommendation to frequency of dressing changes

1.Clean the skin around wound and keep the skin dry.

2.Remove the longer white release paper and apply the exposed side of the dressing to the wound. Ensure the wound is completely covered by the dressing. Remove the shorter white release paper.

3.Press film surrounding gently to fix the dressing.

4.Remove the transparent release film.
