Abstract
An apparatus for promoting the clotting of blood comprises a receptacle, at least a portion of which is defined by a mesh having openings therein, and particles of clay retained in the receptacle. In similar apparatuses, bioactive glass or chitosan is retained in the receptacle. An apparatus also comprises a receptacle defined by a mesh having openings therein, and first and second blood clotting materials enclosed in the mesh. In a method of dressing a bleeding wound, a first blood clotting material in particle form is provided and retained in a mesh structure, and a second blood clotting material is provided and incorporated into a material of the mesh structure. The mesh structure is placed on a bleeding wound such that the second blood clotting material contacts wounded tissue of the bleeding wound.
