Abstract: A multi-bar warp knit fabric structure includes a body yarn and a multi-wrapped hybrid yarn. The hybrid yarn incorporates a specialty core unit, an inside textile cover, and an outside textile cover. The inside textile cover is a static-dissipative yarn helically wrapped around the core unit, and the outside textile cover is a surface-conductive yarn helically wrapped around the inside textile cover and the core unit. The hybrid yarn is integrally knit with the body yarn in a repeating stitch pattern alternately zigzaging lengthwise up selected wales of the fabric structure and floating across the fabric structure in a widthwise course direction. The hybrid yarn cooperates with like knitted multi-wrapped hybrid yarns to form a continuous conductive matrix of static dissipative boxes in the fabric structure.

Abstract: The present invention relates to a surgical drain fabric and surgical drain device and surgical sponge for providing a channel of exit or discharge from a wound or wound cavity and, more specifically, a woven surgical drain fabric, woven surgical drains, and woven surgical sponges having finished longitudinal edges useful for drawing wound drainage out of a patient's body. Preferably, the surgical drain fabric, surgical drains, and surgical sponges are woven with conductive yarns and nonconductive yarns so as to provide enhanced drainage characteristics. The fabric, drains, and sponges prepared in accordance with the invention minimize the danger of sluffing and linting and other disadvantages associated with previous surgical drain and sponge materials. A non-stick coating is applied to the external surface of the drain to reduce tissue adhesion to the drain.

Abstract: The present invention relates to a surgical drain fabric and surgical drain device for providing a channel of exit or discharge from a wound or wound cavity and, more specifically, a fabric in the form of a tape having finished longitudinal edges useful for drawing wound drainage out of a patient's body. Preferably, the fabric is knitted in the form of a tape comprised of conductive yarns and nonconductive yarns stitched in a single warp and single weft pattern so as to provide enhanced drainage characteristics. The yarns and knit stitch are chosen to minimize the danger of sluffing and linting and other disadvantages associated with previous surgical drain materials.
