Abstract: A rectal insertion device for relieving gas in a human or animal may include a body coupled to a shaft. A conduit may extend through the body and the shaft. A nose may be coupled to the shaft via one or more nose arms, and the nose may be opposingly positioned to the body. One or more shaft apertures may preferably be formed by portions of the nose arms and nose, and each shaft aperture may be in communication with the conduit. A stopper may be coupled to the shaft, and the stopper may surround a portion of the shaft. The shaft may include one or more grooves which may be depressed into the shaft, and the stopper may include one or more stopper apertures which may extend through the stopper. Preferably, each groove may be aligned with a stopper aperture.
