Topical vacuum-press surgical incisional dressings, surgical adjuncts, hybrids and composites

摘要

A negative pressure wound therapy (NPWT) dressing includes a wick configured for placement over an incision. A transfer assembly includes a compressible, porous core with a permeable cover placed over the core. The transfer assembly is positioned on the wick in fluidic contact and is covered by a dressing cover, which is configured for adhesive attachment to the patient around the incision. A drain slip including a proximal end configured for placement in the incision extends through the wick and the transfer assembly and is configured for connection to a negative pressure source. A NPWT method includes steps of draining a closed incision using negative pressure applied to a drain slip.

主权项

1. A negative pressure wound therapy (NPWT) dressing configured for application to a skin surface over an incision and configured for connection to a negative pressure source, which dressing comprises:
a fluid-permeable wick element configured for placement over the incision; a fluid transfer component configured for placement on the wick element and including an exterior surface; said transfer component configured for connection to the negative pressure source and for transferring fluid from the incision through the wick element and to the exterior surface; said transfer component configured for transmitting negative pressure from the negative pressure source to the incision; a drape placed over the transfer component and adapted for releasable connection to a skin surface around the incision; a slip drain comprising a fluid-impermeable material and having a proximal end adapted for placement in the incision and a distal end communicating with the negative pressure source; and gaps in said wick element and said transfer component configured for allowing said slip drain through to the surface.
