NURSING OR MOUTH MOTION STIMULATING NURSING NIPPLE

摘要

The rigid front part (24) forms a vestibular screen which engages between the gum buds and the lips of an infant. Disc part (33) is integral with the sliding bar (28) and moves axially against the biaising force of the spring (31). The micro switch (26) closes upon that axial movement and starts the emission of a sound, taste, or smell signal. Displacement of the moving portion (33, 28) may be caused by an effort of the tongue exerted onto the rear surface of the disc (33) or by a traction exerted onto the front ring (35).
