Abstract

Apparatus for inhibiting nasal secretions by selective neural stimulation applies an electrical signal to a selected neurally sensitive area of the oral cavity. A method for inhibiting nasal secretions includes the steps of applying an electrical signal to a neurally sensitive area in the oral cavity, such as on opposite sides of the frenulum and beneath the philtrum.

Claims

1. A method for inhibiting nasal secretions, comprising the steps of placing in the oral cavity of the user on opposite sides of the frenulum and beneath the philtrum a pair of electrodes, and generating and applying to said electrodes a stimulating signal, wherein, said step of generating a stimulating signal is performed by generating a series of positive pulses having pulse widths of about one second, and spacing said pulses by about one second.

2. A method in accordance with claim 1, wherein said step of forming said pulses is so performed that said pulses have amplitudes which increase stepwise to a maximum.

3. A method in accordance with claim 2, wherein said step of generating a stimulating signal includes the further step of generating negative pulses during the intervals between said positive pulses, so that the net D.C. output per cycle is zero.

4. Apparatus for inhibiting nasal secretions by selective neural stimulation, comprising:

a pair of means for placement beneath the upper lip of a user of the apparatus and adjacent to the philtrum;

hand-holdable mounting means coupled to said electrode means for supporting said electrode means and spacing said electrodes relative to each other, the spacing of said electrode means being such as to facilitate placement of said electrode means at respective opposite side of the frenulum, and an electrical signal generator electrically coupled to said electrode means, said electrode means and portions of said mounting means being selectively placeable in the oral cavity of a user so as to apply a signal generated by said signal generator to the region of the oral cavity beneath the upper lip of a user adjacent to the philtrum and on opposite sides of the frenulum.

5. Apparatus in accordance with claim 4, and a housing having said signal generator disposed therein, said electrode means and said mounting means being operatively coupled to said housing, said housing comprising handle means for positioning said electrodes.

6. Apparatus in accordance with claim 5, and a base member complemental with said housing whereby said apparatus may be supported by said base member, a power supply in said housing for driving said signal generator, and means in said base member for selectively charging said power supply when said housing is received in said base member.

7. Apparatus in accordance with claim 4, wherein said signal generator comprises means for providing a signal which comprises a series of positive pulses of about one second in duration each made up of individual pulses of about 0.5 msec. duration, said positive pulses being spaced from each other by about one second.

8. Apparatus in accordance with claim 7, wherein said signal generator includes means for providing negative pulses during those intervals in which said positive pulses are off, whereby the net D.C. output per cycle is zero.

9. Apparatus in accordance with claim 8, wherein said positive pulses are ascending stepped pulses.

10. Apparatus in accordance with claim 8, and switch means associated with said housing and said signal generator for activating said signal generator and timer means responsive to said switch means, said timer means enabling said signal generator to produce an output for a predetermined period and then turning said signal generator off.

11. Apparatus in accordance with claim 7, wherein said signal generator comprises means for producing a series of positive pulses of ascending stepped waveform up to a maximum of about six volts, with a pulse width of about one second and a frequency of about 30 Hz.

12. Apparatus in accordance with claim 11, wherein said signal generator comprises means for producing negative pulses during those intervals in which said positive pulses are off, whereby the net D.C. output per cycle is zero.

13. Apparatus in accordance with claim 12, wherein said signal generator comprises multivibrator means and power amplifier means.

14. For use in apparatus for inhibiting nasal secretions by selective neural stimulation comprising a signal generator and electrode means for applying to a user a signal generated by said signal generator, said electrode means comprising:

a spaced pair of electrodes shaped for placement beneath the upper lip of a user of the apparatus adjacent to the philtrum, mounting means coupled to said electrodes for supporting said electrodes and spacing said electrodes relative to each other, said mounting means comprising support members coupled to respective electrodes of said pair, means coupled to and interconnecting said support members to maintain said respective electrodes and said rod members in spaced relation with respect to each other, the spacing of said electrodes being such as to facilitate placement of said electrodes at respective opposite sides of the frenulum of a user, and electrical connector means operatively associated with said last-mentioned means for selectively electrically coupling said electrodes to a signal generator.
