Bleeding Ugi

This study aims to evaluate the efficacy and safety of a novel blood sensing capsule (PillSense), to help emergency doctors better evaluate if patients have active upper digestive tract bleeding, to determine if they can be discharged safely. The PillSense System consists of the PillSense Capsule, a small single use capsule that is safe for human consumption and PillSense Receiver, an external real-time monitor for data display to detect the presence of bleeding in the upper digestive tract within 10 minutes.
