Abstract
The present invention provides a medical dressing article and a method of manufacturing the same, which comprises: (a) a first layer comprised of polycaprocaptone fibers having a PCL fiber diameter of 0.5 μm and 2.9 μm; (b) a second layer, deposited directly on the first layer, including a mixture of polycaprolactone and poloxamer fibers (PCL and POX fibers) wherein a PCL and POX fiber diameter is between 0.1 μm and 4 μm; and (c) a third layer, deposited directly on the second layer, further comprising a mixture of gelatin and silver nitrate (AgNO3).
Claims20
A medical dressing article, comprising:
- a first layer comprised of polycaprocaptone fibers having a PCL fiber diameter between 0.5 μm to 2.9 μm;
- a second layer including a mixture of polycaprolactone and poloxamer fibers (PCL and POX fibers) wherein PCL and POX fiber diameters are between 0.1 μm to 4 μm;
- and
- a third layer further comprising a mixture of gelatin and silver nitrate (AgNO3), wherein said third layer is configured to make direct contact with a wound, said second layer is directly deposited directly on said third layer, and said first layer is directly deposited on said second layer.
A method of fabricating a medical dressing article, comprising:
- (i) forming a first layer of polycaprocaptone fibers having PCL fiber diameters are between 0.5 μm to 2.9 μm;
- (j) forming a second layer directly on said first layer, said second layer including a mixture of polycaprolactone and poloxamer fibers (PCL and POX fibers) wherein PCL and POX fiber diameters are between 0.1 μm to 4 μm;
- and
- (k) forming a third layer directly on said second layer, said third layer further comprising a mixture of gelatin and silver nitrate (AgNO3).
