Description

A MECHANICAL POSITIVE PRESSURE AIRWAY SECRETION-CLEARING

DEVICE

Field of Invention

The present disclosure relates to a mechanical positive pressure airway secretion-clearing device. While an application of the present disclosure is in the clearing of airway secretions by a person in need of such clearing, the disclosed device could find application in the improvement of breathing efficiency and the reduction of fatigue of respiratory muscles experienced by sportsmen and sportswomen. Additional application of the disclosed device could be found in training mountain climbers to manage the fatigue of respiratory muscles challenges associated with breathing at high altitude.

Background of the Invention

Build-up of airway secretions are observed in patients having acute infections including bacterial, fungal, and viral infections, asthma, chronic diseases including primary ciliary dyskinesia, non-cystic fibrosis bronchiectasis, panbronchiolitis, chronic obstructive pulmonary disease (COPD), cystic fibrosis, hematologic malignant conditions, inflammatory airway diseases, malignant lung conditions, and patients with compromised immunity as observed in human immunodeficiency virus infection, hypogammaglobulinemia, and organ transplantation. As will be appreciated, a person experiencing a build-up of such airway secretions is faced with both mental and physiological distress. Accordingly, there is a need for a device that promotes clearance of airway secretions, in particular a device that is readily available for use, is easy to keep clean, and readily sealable to prevent ingress of particulate matter and pathogenic materials.

Summary

For present purposes, airway secretions should be understood to include the secretions of submucosal glands, i.e., mucins and liquids, secretions associated with a pathologic state, secretions associated with the clearing of particulate matter, secretions having viscosity that exceeds that of a healthy physiologic state, and the like. The present disclosure in one aspect sets out a mechanical positive pressure airway secretion-clearing device. The device including a body. The body including a base, a stem, a mouth aperture at the base, and an aperture at one end of the stem opposite the base. The mouth aperture being configured for insertion into at least a portion of a mouth of a human, the body including a channel extending from the mouth aperture to the aperture at the end of the stem. The device also including a mouthpiece cap configured to lockably engage the base.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
