COLONOSCOPY PRESSURE RETENTION DEVICE

The pressure retention device includes a bottom flange configured to fit within a patient's intergluteal cleft in contact with an anal opening. A neck portion extending from the bottom flange has a co-axial channel therethrough to slidably receive an endoscope. An upper portion at an end of the neck portion has a pair of radially-extending resilient flaps that, when folded radially inward, form an insertion tip that relaxes to extend radially after insertion through the anal sphincter. An annular seal within the co-axial channel seals over the outer surface of the endoscope so that release of a pressurizing fluid through the anal sphincter is resisted. The components are molded as a single piece from a flexible silicone material.
