Title: 

Tinnitus diagnosis and treatment device. 

Protection status: 

European Patent No. EP3498166 

Subject: 

Therapy in the form of a medical service using an innovative magnetic field inductor, which is part of a set for electrical and magnetic stimulation of the ear in tinnitus. The therapy consists in stimulation of the auditory pathway with alternating current or magnetic field with individually selected parameters from the range of frequencies audible to the human ear (i.e. 20Hz-20000Hz, alternating current in the range of 0-2mA, magnetic field 0-28mT). 

Benefits: 

The technology provides a technical effect in the form of increased concentration of the electric or magnetic stimulus in the area of the stimulated structures, i.e. the cochlea and the auditory nerve giving much better therapeutic results. 

There are no devices on the Polish or foreign market dedicated exclusively to tinnitus therapy, combining electrical and magnetic stimulation of the ear. 

Stage of work: 

The solution consists of the following components: a computer program, stimulator that generates electrical and magnetic stimulus, an innovative magnetic field micro-injector, earphone equipped with a system that keeps the electrode and coil in the ear, additional equipment for diagnostics (mapping tinnitus parameters). 

Tests performed include electrical safety testing at the OBAC Attestation and Certification Testing Center, electromagnetic compatibility testing, and preliminary clinical testing. 

Application: 

The device is designed to perform electro or magnetostimulation of the ear using a non-invasive method – inserting a coil or electrode into the ear canal. In this method, the stimulating electrode is placed in the external ear canal, filled with saline solution. The passive electrode is placed on the forehead in the midline of the body. Magnetic field stimulation is performed similarly – using a micro coil also placed in the ear canal. Thanks to such localization of the coil and active electrode, we bring the therapeutic stimulus as close as possible to the effector (which is the cochlea and auditory nerve) achieving optimal intensity in these regions.
