摘要:
Das textile Flächengebilde (10) dient zur Wundversorgung ähnlich dem Verbandmull mit gegenüber diesem verbesserten Eigenschaften und besteht aus einem mittleren Bahnabschnitt (120) aus Chemiefasergarnen (121,122) mit einer hohen Oberflächenspannung und zu beiden Seiten des Bahnabschnittes (120) ausgebildeten Bahnabschnitten (110) aus saugfähigen, cellulosischen Garnen (111,112), wobei der Bahnabschnitt (120) durch Vermaschung mit den Bahnabschnitten (110) verbunden ist, so daß nach einem Faltungsvorgang eine nicht mit der Wunde verklebende Kompresse erhalten wird, bei der der hydrophobe Chemiefaserteil als Wundabdeckung auf der Wunde zu liegen kommt, während die dahinterliegenden Faltlagen aus den cellulosischen Fasern als Saugschicht wirken.

摘要:
The present invention relates to an adhesive interface bandage intended for direct application to a wound. This adhesive interface bandage comprises a cohesive non-adherent gel formed of a hydrophobic elastomeric matrix composed of a triblock elastomer such as styrene - (ethylene - butylene) - styrene or styrene (ethylene - propylene) - styrene, optionally combined with a diblock copolymer such as styrene - (ethylene - butylene) or styrene (ethylene - propylene). Said elastomer is highly plasticised using a mineral oil, and contains a low amount of hydrophilic particles of a hydrocolloid dispersed therein. The adhesive interface bandage additionally comprises a flexible, open-mesh fabric that contains threads coated in the cohesive non-adherent gel such that the mesh is substantially unblocked, characterised in that the fabric is a heat-set knit with weft threads, said threads being continuous threads with non-elastic filaments. In the transverse direction, said fabric has an extensibility measured according to standard EN 13726-4 in the range of 0.01 and 0.5 N/cm.
摘要:
The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from a biocompatible polymer suitable for use in the body and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix distributed on the first and second surfaces and through the fabric substrate, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable proteinaceous polymer.
摘要:
A composite fabric comprising a combination of a gel-forming yarn and a reinforcing yarn. A method of making a reinforced absorptive fabric comprising the steps of weaving, knitting or braiding together gel-forming yarn with reinforcing yarn, such that the network of reinforcing yarn provides structural integrity to the fabric independent of the gel-forming yarn. A composite fabric or structure may also comprise a composite yarn in which is incorporated both gel-forming fibre and reinforcing fibre. Gel-forming fabrics or structure may be made by first forming fabrics or structures of gel-forming fibre precursor and then converting the precursor to its gel-forming state.
