A nosepiece for respiratory therapy with separate gas flows
A recently granted patent (Publication Number: US11724056B2) describes a nosepiece for respiratory therapy. The nosepiece consists of multiple lumens and a hollow bridge that connects them. The first lumen has an enlarged portion that can receive a third lumen, while the second lumen has an enlarged portion that can receive a fourth lumen. The bridge, which is entirely confined between the first and second lumens, forms a fluid conduit between them. It also has an opening along its base that allows for the attachment of a medical device, such as a nebulizer.
The nosepiece is designed to provide respiratory therapy by delivering breathing gas through the lumens. The internal diameters of the lumens can taper towards the outlet ends, and the inlet ends can have larger internal diameters than the outlet ends. The outer surfaces of the lumens are made from various materials, including polyvinyl chloride (PVC) plastic, silicone, and flexible plastic. The bridge itself is collapsible.
The patent also describes a system for respiratory therapy that includes the nosepiece, as well as a source of breathing gas connected to the inlet ends of the third and fourth lumens. The system allows for the humidification and heating of the breathing gas. The lumens and the nosepiece define constant diameter flow paths for the breathing gas, ensuring efficient delivery.
The method for manufacturing the nosepiece involves coating fixed mandrels with a material, curing the coating, trimming the coated mandrels to create openings, and removing the cured coating from the mandrels. The coated mandrels form the lumens and the bridge of the nosepiece.
Overall, this patent presents a novel nosepiece design for respiratory therapy that allows for the attachment of a medical device and efficient delivery of breathing gas. The system and manufacturing method described in the patent further enhance the functionality and production of the nosepiece.
