Abstract
Abstract There is disclosed an improved temperature responsive pacifier assembly having a liquid medium disposed in an interior chamber, and a temperature-responsive element comprised of a spacer strip or element having one or more temperature display dots mounted thereon and formed of a liquid crystal material coated on a colored substrate. The liquid crystal material is responsive to a temperature above about 98.6° F. whereby the liquid crystal material clears to expose the colored substrate thereby visually indicating an abnormal temperature condition of a mammal, and in particular, a homo sapien, orally utilizing such improved pacifier assembly.
