Filed:

Jan 2, 1975

Appl. No.:

5/537894

Inventors:

Jack A. Vernon - Portland OR

Abstract:

Iontophoresis apparatus for applying local anesthetics to selected locations of animal bodies, particularly to the eardrum, comprises an electric circuit providing a source of direct current of constant and predetermined magnitude. Connected into the electric circuit are a first electrode adapted for placement in a quantity of ionized liquid anesthetic and a second electrode adapted for placement in contact with the body in a spaced location. A current adjustment circuit adjusts the current to selected values. Application of a constant current which may be progressively increased or diminished at the will of the operator provides effective iontophoretic action resulting in efficient anesthetization of the body area without adverse effects.

A61B 512
A61M 2100

US Classification:

128746

Abstract:

A tinnitus patient is subjected to external sounds of different pitch, one after another, to enable the patient to identify the particular external sound having the same pitch as the subjective tinnitus sound perceived by the patient. Then the patient is provided with a power operated sound generator producing a range of frequencies extending above and below said perceived pitch to mask the tinnitus sound. The sound generator may be worn in the same manner as a hearing aid and may be combined with a hearing aid if necessary.
