Clay-based Hemostatic Agents and Devices for the Delivery Thereof

device capable of providing a hemostatic effect on bleeding wounds, gauze bandages and hemostatic sponges. a hemostatic device for promoting blood clotting includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least some of the clay material comes into contact with the blood emanating from the wound to cause clotting. A gauze bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. a hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.
