Legionarius is a wearable system integrated into shirts and pants that stops the bleeding from gunshot, stab, and blast wounds, and provides remote triage capabilities. It detects impact to the body and sends out an encrypted distress signal to first responders, which includes the severity of the wound, vital signs, and the geolocation of the user. Within seconds, it applies pressure to the wound to stop bleeding. Autonomously and automatically.
