Vibratory Nerve Exciter

Abstract

A laryngeal nerve exciting system includes a collar holding a bridge, or a neckband, pressing soft tissue nerve exciters against a patient's neck providing a source of vibrations to stimulate the laryngeal nerve through the larynx. At least one exciter, and preferably two exciters, provide vibrations at preferably 70 Hz to 110 Hz and sufficiently strong to penetrate to the laryngeal nerve. The exciters may be held by the collar circling the neck, or by the neck band partially circling the neck. The therapy system includes a Personal Digital Assistant (PDA) and software which wirelessly connects, monitors, and triggers the device. The system may be used to treat dysphagia, chronic cough, and spasmodic dysphonia.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the priority of U.S. Provisional Patent Application Ser. No. 62 / 836,195 filed Apr. 19, 2019 which application is incorporated in its entirety herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to human tissue stimulation and in particular to noninvasive vibration on the neck overlying the larynx to excite the laryngeal nerve to augment or reestablish swallowing control during rehabilitation of patients with dysphagia, and to treat voice disorders affecting the function of the laryngeal system, such as spasmodic dysphonia, and to treat chronic cough.[0003]Dysphagia is a major swallowing disorder that affects the central nervous system, and the peripheral nervous system, thereby weakening neuromuscular control and effectively reducing the ability to properly swallow. Dysphagia may occur at any time across the lifespan. This impairment has many potential causes, including but not...

AI Technical Summary

Benefits of technology

[0008]The present invention addresses the above and other needs by providing a vibrating laryngeal nerve exciting device which includes a collar holding a bridge, or a neckband, pressing soft tissue nerve exciters against a patient's neck providing a source of vibrations to stimulate the branches of the vagus nerve, such as the recurrent laryngeal, superior laryngeal, and pharyngeal branches. At least one exciter, and preferably two exciters, provide vibrations preferably adjustable between 30 Hz and 200 Hz and

Problems solved by technology

Dysphagia is a major swallowing disorder that affects the central nervous system, and the peripheral nervous system, thereby weakening neuromuscular control and effectively reducing the ability to properly swallow.

Dysphagia is characterized by difficulty swallowing, impaired ability to protect the airway during swallowing (penetration and aspiration), and impaired ability to transport a bolus of food or liquid from the mouth to the stomach.

These difficulties may contribute to a risk for respiratory complications (pneumonia), dehydration, malnutrition, and may restrict
