摘要:
The present invention relates to a wound healing PVA sponge dressing using negative capillary pressure of the dressing material together with auxiliary negative pressure for wound treatment. The PVA sponge dressing is pretreated with gram positive and gram negative biocidal dyes for insertion into or over a wound. A negative pressure pump is mounted to the PVA sponge dressing to produce additional capillary pressure for withdrawing fluid or water vapor from the sponge dressing and a cover is mounted over the sponge material and negative pressure pump forming a unitary sealed package for placement over a wound.
