Blood clotting compositions and wound dressings

Abstract

In general, the basic material forming the wound dressing, covering, and/or application system of the present invention for use in blood coagulation comprises a combination of one or more components selected from the group consisting of clay materials, a molecular sieve material, principally zeolite, and inorganic oxide materials. Although the actual process which enables the wound dressing, covering, and/or application system of the present invention to effectively coagulate flowing blood is unknown, it is believed that the molecular sieve material selectively absorbs small molecules, such as water, from the blood. Due to the absorption of the water molecules, it is believed that the rate of blood clotting is increased.

1 . A method for promoting blood coagulation comprising: applying a wound dressing, covering, or application system to a bleeding area, wherein the wound dressing, covering, or application system comprises:
 a clay material; and   a gauze pad, a multiple layer cover, or a permeable bandage.   
   
   
       2 . The method of  claim 1 , wherein the clay material comprises kaolin or kaolinite. 
   
   
       3 . The method of  claim 1 , wherein the clay material consists essentially of kaolin or kaolinite. 
   
   
       4 . The method of  claim 1 , wherein the clay material comprises bentonite. 
   
   
       5 . The method of  claim 1 , wherein the clay material consists essentially of bentonite. 
   
   
       6 . The method of  claim 1 , wherein the clay material comprises montmorillonite. 
   
   
       7 . The method of  claim 1 , wherein the clay material consists essentially of montmorillonite. 
   
   
       8 . A method for promoting blood coagulation comprising:
 applying a clay material to a bleeding area; and   applying a gauze pad, a multiple layer cover, or a permeable bandage to a bleeding area.   
   
   
       9 . The method of  claim 8 , wherein the clay material comprises kaolin or kaolinite. 
   
   
       10 . The method of  claim 8 , wherein the clay material consists essentially of kaolin or kaolinite. 
   
   
       11 . The method of  claim 8 , wherein the clay material comprises bentonite. 
   
   
       12 . The method of  claim 8 , wherein the clay material consists essentially of bentonite. 
   
   
       13 . The method of  claim 8 , wherein the clay material comprises montmorillonite. 
   
   
       14 . The method of  claim 8 , wherein the clay material consists essentially of montmorillonite.
