Claims18
A method of providing wound filler at a wound site prior to application of negative pressure wound therapy, the method comprising:
- first, securing a drape over a wound cavity to form a seal;
- second and subsequently to forming the seal, injecting a liquid foam filler material through an aperture in the drape, the liquid foam filler material configured to expand outward as the liquid foam filler material cures into a solid and substantially fills an entire volume of the wound cavity, the liquid foam filler material applying an outward force a against the wound cavity and the drape and thereby directing the expanding foam filler through the aperture without causing the seal to lift away from the wound cavity;
- and
- third, removing excess foam filler material which flows out through the aperture.
