Clay-based hemostatic agents and devices for the delivery thereof

A bandage applicable to a bleeding wound, said bandage comprising:

• a flexible substrate;
• a gauze substrate mounted on said flexible substrate;
• a clay material disposed on said gauze substrate;
• and
• a water-soluble polyol binder disposed on said gauze substrate to bind said clay material to said gauze substrate;
• wherein the gauze substrate initially exists separately from the clay;
• wherein the polyol binder has an effect of substantially suppressing clay dust;
• and
• wherein said device is dry in that it is not saturated with a liquid and the device is configured such that when treating bleeding, application of said bandage is capable of causing at least a portion of said clay material to come into contact with blood to assist in accelerating cloning.

A hemostatic sponge, comprising:

• a gauze substrate having a first surface;
• and
• a dispersion of a hemostatic clay material and a water-soluble polyol binder disposed on said first surface of said gauze substrate;
• wherein the gauze substrate is provided separately from the clay when the sponge is made;
• wherein the polyol binder has an effect of substantially suppressing clay dust;
• and
• wherein said device is dry in that it is not saturated with a liquid and the device is configured such that when treating bleeding, application of said hemostatic sponge is capable of causing at least a portion of said hemostatic material to come into contact with blood to assist in accelerating clotting.

A hemostatic sponge, comprising:

• a first substrate;
• a hemostatic material dispersed in a water soluble polyol binder and applied to said first substrate;
• and
• a second substrate disposed on said hemostatic material dispersed in said polyol;
• wherein said device is dry in that it is not saturated with a liquid and the device is configured such that when treating a bleeding wound, application of said hemostatic sponge is capable of causing at least a portion of said hemostatic material to come into contact with blood through at least one of said first substrate and said second substrate.
