Abstract

A system for respiratory therapy that includes 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 for respiratory therapy 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.

8. The system of claim 7, wherein the nebulizer coupling port is configured to be slidably received within the nebulizer outlet port.

9. The system of claim 1, wherein the at least one nasal prong comprises a pair of nasal prongs, and the attachment device is positioned directly adjacent a base of one of the pair of nasal prongs.

10. The system of claim 9, wherein the one of the pair of nasal prongs is shorter than another one of the pair of nasal prongs.

11. The system of claim 1, wherein the attachment device is configured to position the adaptor outlet port directly below a nare of the patient when the nasal cannula is secured to the patient.

12. The system of claim 1, wherein the attachment device comprises a loop configured to receive a portion of the adaptor therethrough.

13. The system of claim 1, wherein the nasal cannula further comprises a nasal cannula body and tubing connected to the nasal cannula body for supplying breathing gas to the nasal cannula body.

14. A method of providing respiratory therapy to a patient, the method comprising:

securing a nasal cannula to the patient;

attaching an adaptor to the nasal cannula using an attachment device such that an adaptor outlet port of the adaptor is positioned adjacent to an outlet of a nasal prong along the nasal cannula;

generating an aerosolized medicament with a nebulizer;

transferring the aerosolized medicament into the adaptor through a nebulizer coupling port of the adaptor; and

providing a flow of breathing gas to the patient through the nasal prong such that the aerosolized medicament is drawn outward from the adaptor through the adaptor outlet port for inhalation by the patient with the flow of breathing gas;

wherein the nasal prong has a first longitudinal axis and wherein the adaptor outlet port has a second longitudinal axis, wherein the first longitudinal axis is laterally offset from the second longitudinal axis.

15. The method of claim 14, wherein the providing step comprises drawing the aerosolized medicament outward from the adaptor through the adaptor outlet port having a cross-sectional area less than the nebulizer coupling port.

16. The method of claim 14, wherein the attachment device comprises a loop, and the step of attaching comprises:

positioning a protrusion of the adaptor within the loop.

17. The method of claim 14, further comprising the step of:

removably attaching the adaptor to the nebulizer.

18. The method of claim 17, further comprising the step of:

venting a portion of the aerosolized medicament from the adaptor using a vent hole provided in the adaptor.
