Endoscopic bite block, oxygenating

Intended purpose

TwinGuard is a nasal oxygen cannula and bite block and is used during endoscopy procedures to administer continuous oxygen to the nose and mouth. After endoscopy the bite block is removed, leaving the cannula in place during recovery, to continue delivering oxygen to the nose and mouth. In addition, the TwinGuard contains an optional accessory which collects samples of the patient?s breathing at the nose and mouth to measure CO2 with a capnograph during endoscopy procedures.
