Claims14
A flexible hemostatic pad comprising:
- a substrate comprising a flexible velvet-like fabric, wherein the flexible velvet-like fabric comprises fibers extending vertically from the substrate;
- and
- a hemostatic powder comprising an insoluble cation exchange material, wherein the hemostatic powder has been compressed into the velvet-like fabric to achieve a hemostatic powder depth of from 0.7 mm to no more than 2 mm, wherein the compressed hemostatic powder and the fibers are locked together, wherein the flexible hemostatic pad comprises a layer of compressed hemostatic powder disposed above the fibers, and wherein the compressed hemostatic pad into which the hemostatic powder has been compressed remains flexible and will not break when bent.
A flexible hemostatic pad comprising a velvet-like substrate comprising a flexible velvet-like fabric comprising fibers extending vertically from the substrate, and a hemostatic powder comprising an insoluble cation exchange material made by compressing the hemostatic powder into the velvet-like substrate with a compression force of between 7,244 psi and 10,000 psi such that the hemostatic powder has a depth of no more than 2 mm, wherein the compressed hemostatic powder and the fibers are locked together, wherein the flexible hemostatic pad comprises a layer of compressed hemostatic powder disposed above the fibers, and wherein the compressed hemostatic pad into which the hemostatic powder has been compressed remains flexible and will not break when bent.
