摘要:
Devices for providing respiratory therapy to a patient are disclosed. One device includes first and second elongated lumens and a nosepiece. The elongated lumens each have a constant internal diameter. The nosepiece portion has a third lumen and a fourth lumen. The third and fourth lumens have constant internal diameters equal to those of the first and second lumens. The third and fourth lumens have inlet ends adapted to be connected to the outlet ends of the first and second lumens without constricting the internal diameter of the first and second lumens. The third and fourth lumens are configured to receive first and second flows of breathing gas from the first and second lumens and deliver the flows of breathing gas to outlets end of the third and fourth lumens. The second flow of breathing gas is maintained separate from the first flow of breathing gas within the nosepiece portion.

摘要:
Systems and methods for respiratory therapy are disclosed. The system (100) may include a nebulizer (110), an adaptor (130), and a nasal cannula (150). The nebulizer is operable to generate an aerosolized medicament and pass it through a nebulizer outlet port (112). The adaptor has a nebulizer coupling port and an adaptor outlet port (136). The cannula is configured to provide a flow of breathing gas from a source to the patient. The cannula comprises a cannula body (156) having at least one nasal prong (160), an attachment device (162), and a supply tube (152,154) for enabling fluid communication between the cannula body and the source. The attachment device is configured to secure the adaptor outlet port adjacent an outlet of the nasal prong. The method includes securing a nasal cannula to the patient, attaching an adaptor to the cannula, generating aerosolized medicament, transferring the aerosolized medicament into the adaptor, and providing a flow of breathing gas to the patient.
摘要:
Provided herein are devices, systems, and methods for providing respiratory therapy to a patient using a nasal cannula comprising a cannula body, first and second inlet tubes, and a nasal prong for the delivery of a flow of breathing gas to the patient. Configured with the cannula is a nebulizer having an aerosol generator positioned to emit aerosolized medicament along a longitudinal axis of the nasal prong. A flow director is configured to direct the flow of breathing gas into the nasal prong such that the breathing gas flows along the longitudinal axis, such that the flow of aerosolized medicament is contained within the flow of breathing gas as it moves along the longitudinal axis of the nasal prong for delivery to the patient.
