  • Low birth weight infant pacifier
    Patent number: 5275619
    Abstract: A pacifier for use with premature and other low birth weight infants, which is configured dependent upon the shape of a small infant's thumb and palatal cavity. The pacifier has a shield and a nipple. The nipple is longer and thinner than previously known pacifiers, and comprises a relatively soft, narrow shaft connecting a bulbous tip to the shield. The tip is configured to provide optimal palatal stimulation while the infant sucks on the pacifier, while the shield is shaped to simultaneously provide optimal perioral stimulation.
