Abstract
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.
Claims20
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 adapted for placement over the incision;
- a fluid transfer component placed on the wick element and including an exterior surface;
- said transfer component configured for connection to the negative pressure source and 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;
- and
- a drain slip 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.
A negative pressure wound therapy (NPWT) method, which comprises the steps of:
- placing a fluid-permeable wick over a wound;
- placing a transfer component over the wick;
- draping said transfer component with a membrane;
- attaching said membrane to a patient's skin surface around said transfer component;
- extending a slip drain proximal end into the wound;
- extending the slip drain through the wick and the transfer component;
- applying a negative pressure to said transfer component;
- and
- extracting fluid from said wound via said wick, transfer component and slip drain.
