Abstract: The present invention relates to hemostatic fabric materials, and to the methods for making and using such materials. In particular, the present invention relates to hemostatic fabric materials made from chemically treated plant materials that are soluble on wound surfaces.

Abstract: A preformed seam, crease, or fold in the bottom portion of a surgical, procedural, or personal protection mask forms a chin pocket in the bottom of the mask to receive the user's chin therein. This pocket has been found to provide a better mask fit to reduce the air leakage around the mask not only around the user's chin, but around the entire face. The mask may also have a unique construction of the filter material which includes a filter layer and a moisture resistant layer. The mask also may include a soft comfortable layer for placement against the face of a user. The filter layer can provide an activated charcoal filter and/or a particulate filter which allows gas to pass therethrough but resists passage of bacteria, viruses, and particulate materials.
