Abstract

A stimulator for inducing salivation by neural stimulation comprises a housing which may be received in the oral cavity of a user, the housing enclosing electronic signal generating means and electrodes for applying a signal to neurally sensitive areas of the oral cavity to induce salivation. In its method aspect, the invention involves stimulation of salivation by the application of an electrical signal to neurally sensitive areas.

Claims

1. A method for stimulating salivation, comprising the steps of locating and stimulating the nerves of the oral cavity of a user to identify areas which are sensitive to neural stimulation by electrical means, placing in the oral cavity of the user means for generating and applying a stimulating signal directly to said areas, and applying said signal directly to at least one of said areas.

2. A method in accordance with claim 1 wherein said steps of locating and stimulating are performed by applying to the areas an electrical signal of a kind similar to the signal produced by the means for generating and applying a stimulating signal.

3. A method in accordance with claim 2, wherein the stimulating signal consists of a series of pulses having an amplitude of about three to five volts, a pulse width of about 500 microseconds and a frequency of about 30 Hz.

4. A method in accordance with claim 3, wherein the stimulating signal is turned on and off at intervals of about one-half second.
