The present invention extends to a wound treatment system and a method of using the wound treatment system to treat a flesh wound such as from a gunshot, knife, or shrapnel. The wound treatment system comprises an applicator that contains absorbent material, and a plunger. The applicator is configured to be inserted into a flesh wound to inject the absorbent material directly at the source of bleeding. In this manner, the absorbent material is less likely to become contaminated and can apply direct internal pressure to the source of bleeding to mitigate the risk of serious injury or death from blood loss.
