5. The device of claim 1 wherein the lower structural element is selected from the group consisting of an aqueous absorbent layer, a film, a pad, a pull-tape, and a string,
the lower structural element being adhered to at least the second end of the bottom layer with sufficient force that the structural element will not tear as the second end of the bottom layer is progressively separated from the surrounding edge structure.
6. The device of claim 2 wherein the lower structural element is selected from the group consisting of an aqueous absorbent layer, a film, a pad, a pull-tape, and a string,
the lower structural element being adhered to at least the second end of the bottom layer with sufficient force that the structural element will not tear as the second end of the bottom layer is progressively separated from the surrounding edge structure.
7. The device of claim 3 wherein the lower structural element is selected from the group consisting of an aqueous absorbent layer, a film, a pad, a pull-tape, and a string,
the lower structural element being adhered to at least the second end of the bottom layer with sufficient force that the structural element will not tear as the second end of the bottom layer is progressively separated from the surrounding edge structure.
8. The device of claim 4 wherein the lower structural element is selected from the group consisting of an aqueous absorbent layer, a film, a pad, a pull-tape, and a string,
the lower structural element being adhered to at least the second end of the bottom layer with sufficient force that the structural element will not tear as the second end of the bottom layer is progressively separated from the surrounding edge structure.
9. A device for carrying then delivering a sterile hemostasis material to a traumatic wound comprising:
a packet comprising a non-porous surface with an indented area therein and a surrounding edge structure defining a perimeter around the indented area;
within the indented area is a sterile hemostatic mass capable of clotting mammalian blood when the sterile hemostatic mass contacts mammalian blood;
a bottom layer of non-porous film attached by a tacky adhesive to the surrounding edge structure to secure the sterile hemostatic mass within the packet, said bottom layer having a first end and a second end; and
a lower structural element comprising an aqueous absorbent pad below the bottom layer and away from the sterile hemostatic mass, and
the lower structural element is adhered to at least the second end of the bottom layer such that when the aqueous absorbent pad is progressively manually pulled parallel to the surrounding edge structure, the second end of the bottom layer is progressively separated from the surrounding edge structure so that the sterile hemostatic mass is exposed, and
wherein the lower structural element further comprises an aqueous absorbent sheet to absorb blood from the traumatic wound before or during the pulling of the lower structural element.
10. The device of claim 9 wherein a top surface of the packet has a handle attached thereto.
11. A method of treating a traumatic wound from which blood of a mammal is being exposed on tissue, comprising:
providing a device for carrying then delivering a sterile hemostasis material to a traumatic wound, the device comprising:
a packet comprising a non-porous surface with a recessed area therein and a surrounding edge structure defining a perimeter around the recessed area, said packet having a leading edge and a rearward edge;
within the recessed area is a sterile hemostatic mass capable of clotting mammalian blood when the sterile hemostatic mass contacts mammalian blood;
a bottom layer of non-porous film is attached to the surrounding edge structure to secure the sterile hemostatic mass within the packet, said bottom layer having a first end and a second end corresponding respectively to the leading edge and the rearward edge of the packet; and
a lower structural element below the bottom layer, away from the sterile hemostatic mass, and adhered to at least the second end of the bottom layer such that when the lower structural element is progressively pulled parallel to the surrounding edge structure, the second end of the bottom layer is progressively separated from the surrounding edge structure, exposing the sterile hemostatic mass in proximity to the wound;
contacting the leading edge of the packet adjacent a side of the wound;
progressively pulling the lower structural element away from the leading edge of the packet to separate at least the second end of the bottom layer from the packet to expose sterile hemostatic mass to the traumatic wound, and further
wherein the lower structural element comprises an aqueous absorbent sheet which absorbs blood from the traumatic wound before or during the pulling of the lower structural element.
12. The method of claim 11 wherein the packet has a handle thereon, and the handle is used to position the device for contact with the wound and to apply pressure to the device as the lower structural element is pulled.
13. The method of claim 12 wherein the bottom layer retracts and folds over itself as the lower structural element is pulled.
14. The method of claim 11 wherein the lower structural element comprises an aqueous absorbent sheet which absorbs blood from the traumatic wound during the pulling of the lower structural element.
