Abstract: The ARS is an adjustable therapeutic support platform for premature and fullterm infants for the positional treatment of gastroesophageal reflux. It is designed in two sizes for use in infant incubators and in hospital/home cribs. It is made of washable plastic and can be positioned at both a 30 and a 45 degree angle. The supportive saddle and quick-release VELCRO straps secure the infant to the board while allowing fast and convenient access to the infant by all caretakers. This arrangement permits unrestrained movement of the infant's arms and legs. Features of the design achieve the objectives of optimum positional treatment of GER, maximum safety and comfort for the infant, maximum and unimpeded convenient access to the infant by caretakers, and maximum convenience for storage.
