Abstract
A rigid hollow tubular adapter releasably attached at a longitudinal nozzle end to a flexible tube during equine nasogastric intubation comprising an annular sleeve having a stationary tubular member and a slidable tubular member. The slidable tubular member is delimited at its ends by the stationary tubular member and a detent member disposed between an equine reflux drainage hole and a longitudinal mouthpiece end. Operator's puffs of airflow through a mouthpiece urges the slidable member to slide toward the detent member closing the equine drainage hole to enable passage of medication into the equine stomach. Equine reflux urges the slidable tubular member to slide toward the stationary tubular member opening the reflux drainage hole to divert equine backflow downwardly through the equine backflow drainage hole preventing passage of equine reflux into the operator's mouth.
