A wound covering typically made of cross-linked polymer gels in sheet form or an amorphous hydrating gel of various formulations intended to promote wound healing by maintaining a moist wound environment; it may also facilitate wound debridement and/or absorb exudates in wounds that are minimally to moderately exudative. It may combine hydrogel with supplemental dressing materials (e.g., alginate, film backing), require the use of a secondary dressing, and/or provide a barrier impermeable to liquids and gases; it does not include an antimicrobial agent(s). This is a single-use device.
