Abstract: The disclosure describes, in various example embodiments, a small arms or firearm projectile including a shell and a hemostatic material retained within the shell. The hemostatic material has a mechanical modulus above 25,000 Pa. In some embodiments, the shell includes a plurality of perforations. In some embodiments, the plurality of perforations are configured to provide, upon an impact of the projectile, fluid communication between the hemostatic material and the exterior of the shell via the plurality of perforations. In some embodiments, the hemostatic material includes a polymer core configured to provide a scaffold for inducing hemostasis in a local wound volume. In some embodiments, the projectile includes a contrasting agent. In some embodiments, the projectile includes a lubricating agent retained in the interior of the shell. In some embodiments, the projectile further includes 0.5 to 3 grains of Kaolin retained in the interior of the shell.

Abstract: In one embodiment, a small arms projectile is described, including a shell and a hemostatic material retained within the shell, wherein the projectile is configured such that the hemostatic material is released upon an impact of the projectile. In some embodiments, the hemostatic material includes one or more of a factor concentrator, a mucoadhesive agent, and a procoagulant supplementor. In some embodiments, the hemostatic material may be configured as an expandable foam, a sponge, a hydrogel, a powder, a compound, a mixture, a suspension, or any combination thereof. In some embodiments, the hemostatic agent is further treated with one or more cauterizing agents, paralytic agents, anesthetic agents, and sedative agents.
