ABSTRACT:
A hand-held depilating device capable of masking the pain of plucking the hairs through psychological effect. The depilating device comprises housing adapted to be grasped by the hand of the user and a plucking head mounted on top of the housing for plucking the hairs from the skin. Stimulator is mounted on top of the housing adjacent to the plucking head for providing mechanical stimuli to the skin while the plucking head operates to pluck the hairs. The stimulator comprises a vibrator which provides vibrations to the skin as the mechanical stimuli which act on sense receptors other than nociceptors that respond to pain, thereby masking the pain caused by plucking the hairs or received at the nociceptors. That is, the mechanical stimuli caused by the vibrations can activate Meissner's corpuscle or Pacinian corpuscle to make indistinct to the pain as demonstrated by a gate-control theory in psychology. Thus, the mechanical stimuli applied separately from the plucking operation can excite the tactile or pressure sense receptors so as to activate the gate control path at posterior horn of the spinal cord immediately before or simultaneously with the plucking the hair, thereby blurring the pain being transmitted through the nerve. Alternately, roller with stimulus projections may be utilized to apply the mechanical stimuli for alleviation of the pain.
