Abstract
A system for respiratory therapy may include a nebulizer, an adaptor, and a nasal cannula. The nebulizer is operable to generate an aerosolized medicament and pass the aerosolized medicament through a nebulizer outlet port. The adaptor has a nebulizer coupling port configured to be coupled to the nebulizer outlet port. The nasal cannula is configured to provide a flow of breathing gas from a breathing gas source to the patient. The nasal cannula includes at least one nasal prong and an attachment device positioned adjacent the at least one nasal prong. The attachment device is configured to secure the adaptor outlet port adjacent an outlet of the nasal prong. A method includes securing a nasal cannula to the patient, attaching an adaptor to the nasal cannula, generating an aerosolized medicament, transferring the aerosolized medicament into the adaptor, and providing a flow of breathing gas to the patient.
Core Innovation
The invention is a system for providing respiratory therapy to a patient using a nebulizer, an adaptor, a syringe, and a nasal cannula. The nebulizer generates an aerosolized medicament and passes it through the adaptor toward an outlet positioned adjacent to a nasal prong, where the aerosolized medicament is delivered in the breathing-gas slipstream.
The adaptor includes a drainage port with an elbow-shaped lumen extending outwardly from the adaptor body, and a syringe coupled to the lumen withdraws liquid medicament from the adaptor body. The nasal cannula attachment device secures the adaptor outlet port adjacent to a nasal-prong outlet; the prong and adaptor outlet axes are parallel and laterally offset. The background section describing the problem being solved is not included in the provided content.
Claims Coverage
The provided claims identify one independent claim comprising three inventive features directed to a respiratory therapy system with a nebulizer, an adaptor, a syringe, and a nasal cannula.
Nebulizer and adaptor arrangement
A nebulizer generates an aerosolized medicament and passes it through a nebulizer outlet port coupled to the adaptor's nebulizer coupling port. The adaptor has an adaptor outlet port.
Syringe-coupled drainage port
The adaptor drainage port enables drainage of liquid medicament from the adaptor body and comprises an elbow-shaped lumen extending outwardly from the adaptor body. A syringe couples to the distal end of the lumen and withdraws the liquid medicament.
Nasal cannula and adaptor positioning
The nasal cannula provides a flow of breathing gas from a breathing gas source to the patient and has at least one nasal prong. An attachment device adjacent to the prong secures the adaptor outlet port adjacent to the prong outlet; the prong axis is parallel to and laterally offset from the adaptor outlet axis.
The independent claim covers the combined nebulizer, adaptor, syringe-connected drainage port, and nasal cannula arrangement, including the specified positioning of the adaptor outlet relative to a nasal prong.
Stated Advantages
Not explicitly described in patent.
Documented Applications
Providing respiratory therapy to a patient by delivering aerosolized medicament through an adaptor positioned adjacent to a nasal cannula prong.
