Abstract
An infant waterbed for use in an incubator is disclosed that comprises a tray, a flexible mattress that sits in the tray and holds a fluid, such as water, that is capable of supporting an infant, a cover that fits over the top of the tray to separate the infant from the mattress, a frame that surrounds the cover and fits over the edge of the tray to hold the cover in place, and an oscillator that includes a bladder that sits under the mattress and means for inflating and deflating the bladder randomly at a predetermined frequency. Compensatory vestibular-proprioceptive stimulation is imparted to premature infants by placing them on the above described oscillating waterbed.
