Inventor unveils dual-material nasal cannula aimed at improving comfort

Danise L. of Rio Rancho, New Mexico, has developed the Comfort Cannula, a modified oxygen tube designed to reduce kinking, twisting and facial pressure during use. The invention is now seeking licensing partners as the inventor pursues a utility patent with the USPTO.

Why it matters: - The Comfort Cannula is designed to address a common tradeoff in oxygen therapy: tubing that is stiff enough to resist kinking can be uncomfortable, while softer tubing can twist or collapse. - The design aims to improve long-term wear for patients who rely on nasal cannulas for standard-flow or high-flow oxygen delivery. - The invention could be attractive to manufacturers and distributors looking for a cannula that balances airflow stability with wearer comfort.

What happened: - Danise L. of Rio Rancho, New Mexico, created the Comfort Cannula, a modified nasal cannula with dual-material tubing. - Danise filed a utility patent with the United States Patent and Trademark Office. - InventionHome is helping market the patent rights for sale or license to U.S.-based product manufacturers or distributors. - Companies interested in the Comfort Cannula can contact InventionHome at member@inventionhome.com. - Inventors seeking help with patenting, marketing or licensing can contact InventionHome at info@inventionhome.com or call 1-866-844-6512.

The details: - The Comfort Cannula uses a single non-kink tube that extends from the oxygen source, passes under the chin and then transitions into two softer tubes along the cheeks and around the ears. - Curved nasal prongs are positioned at the terminal ends to create a more comfortable interface at the nostrils while preserving an open path for oxygen delivery. - The facial portion may use extra-soft medical-grade PVC tubing from the prongs to a point below the ears and above the jawline. - Below the ears, the two tubes merge into one non-kink PVC tube that runs beneath the chin. - A sliding adjustment component lets the user or caregiver adjust fit and secure the tubing to the user's anatomy. - The tubing continues as a single line to the oxygen source and uses a standard flared connection or compatible connector. - The lower section is intended to resist twisting and compression in the area most likely to fold during movement. - The system may be used with standard-flow oxygen systems at about 2 to 6 liters per minute. - High-flow configurations may support about 15 liters per minute or higher. - Actual oxygen concentration and flow characteristics depend on the oxygen source, flow rate, cannula configuration and associated respiratory equipment. - The listed features include dual-material tubing construction, non-twistable lower tubing, curved nasal prongs, medical-grade materials and reduced dependence on external padding.

Between the lines: - The design tries to solve a practical usability problem rather than rethinking oxygen therapy itself. - The dual-material structure suggests the product is aimed at patients who need oxygen for extended periods and may experience skin irritation or discomfort from standard cannulas. - The licensing push indicates the invention is still in a commercialization phase, with the next step likely depending on a manufacturer willing to take the product to market.

What's next: - InventionHome is seeking potential licensing partners to further develop and distribute the Comfort Cannula. - If a manufacturer or distributor takes interest, the next phase would likely involve product refinement, testing and commercialization. - The inventor is also positioned to pursue broader support from InventionHome for patenting, marketing and licensing efforts.

The bottom line: - The Comfort Cannula is pitched as a small but practical redesign that could make oxygen delivery tubing less irritating without sacrificing airflow stability.
