RevMedx’s sponge-filled syringe, the XSTAT 30, was approved for military use in treating gunshot wounds last year. Now, the FDA says paramedics and other first repsonders can use the device to treat civilian injuries as well. The syringe is filled with tiny sponges that are designed to control severe bleeding from wounds in places a tourniquet can’t be used. Each syringe contains 92 compressed sponges that expand to fill the wound to block blood flow for up to four hours.
