A Prospective Pilot Study to Evaluate the Diagnostic Performance of a Wireless Sensor Capsule in Detection of UGIB

HemoPill® acute capsule (Ovesco Endoscopy, Tuebingen, Germany) is a swallowable, wireless, sensor capsule designed for in vivo detection of liquid blood or hematin. The capsule has integrated optical microsensor for blood detection, by transmitting red and violet light via LEDs. It allows the detection of blood by photometric measuring method, in small volumes or in unprepared digestive tract. The dimensions of the capsules are 7.0mm x 26.3mm. The maximal examination time is 9 hours. The HemoPill® receiver is a portable receiver for displaying and storing measured values from the HemoPill® acute capsule. It allows a real-time, wireless, telemetric data transmission. Once activated, the HemoPill® acute capsule can be swallowed by patients with real-time measurement of HemoPill® Indicator (HI). An HI value in the red range suggests a positive finding - liquid blood or hematin has been detected.
