Abstract:
Porous devices are provided that include a particle-containing fibrous porous matrix and a fluid absorbed in the particle-containing porous fibrous nonwoven matrix. The particle-containing fibrous porous matrix includes a porous fibrous nonwoven matrix containing first polyolefin fibers, second polyolefin fibers including poly(ethylene), and fiberglass fibers; and microorganism-binding particles. The microorganism-binding particles are enmeshed in said porous fibrous nonwoven matrix. Methods of debridement are provided including providing a porous device including a particle-containing fibrous porous matrix and wiping a wound or an area of skin with the device; and providing a porous device including a porous fibrous nonwoven matrix and wiping a wound with the device. Further, kits are provided including a sterile package containing at least one porous device, and typically also instructions for debridement.
