Abstract:
1. An apparatus adapted to be applied to a human body to prevent hemorrhage from a skin-penetrating wound comprising: a substantially rigid or semi-rigid structure further comprising a top plate, a bottom plate, and a connector region, wherein the substantially rigid or semi-rigid structure forms a U, C, or open rectangular shape that is open on at least three sides; a wound compression pillow, affixed to an inside aspect of the bottom plate that can be expanded into the wound to provide compression and tamponade of the wound; a liquid impermeable membrane affixed between the wound compression pillow and the inside aspect of the bottom plate; at least one raised dam, affixed to the liquid impermeable membrane, wherein the dam completely surrounds the wound compression pillow and projects away from the liquid impermeable membrane such that the dam forms an edge seal to prevent the escape of blood from the wound; a mechanism to expand the wound compression pillow; a padded region affixed to an inside aspect of the top plate, wherein the padded region is configured to remain stable against the body and provide for force distribution to maximize comfort, and a mechanism to expand the padded region to adjust the tightness with which the apparatus holds the wound compression pillow in the wound, wherein the pressure distribution of the wound compression pillow can be adjusted to exceed systemic arterial pressure and thus provide for hemostasis of the wound.
