Abstract
Disclosed herein are systems, devices, and methods for nasal cannulas allowing simultaneous flow of humidified breathing gas and aerosolized medicament for use in respiratory therapy. Utilizing separate flow paths and separate cannula outlets for the heated and humidified breathing gas and for the aerosolized medicament, these systems, methods, and devices reduce condensation of the aerosolized medicament by delaying mixing of the flow of aerosolized medicament and the flow of heated and humidified breathing gas until the flows exit the cannula.
Claims42
A nasal cannula for delivering humidified breathing gas and nebulized medication, the nasal cannula comprising:
- a first prong having a first outlet, a longitudinal axis, and a length along the longitudinal axis;
- a second prong having a second outlet;
- a first medicament outlet disposed adjacent to the first prong and arranged to pass aerosolized medicament substantially parallel to the longitudinal axis;
- a first tube having a first inlet for receiving breathing gas, the first tube being in fluid communication with the first and second prongs;
- and
- a second tube having a second inlet for receiving aerosolized medicament, the second tube being in fluid communication with the first medicament outlet;
- wherein the first tube is not in fluid communication with the second tube along the length of the second tube.
A method for delivering humidified breathing gas and nebulized medication, the method comprising:
- passing heated and humidified breathing gas through a first conduit to a first outlet and a second outlet of a nasal cannula;
- and
- passing an aerosolized medicament through a second conduit to a third outlet, the second conduit having a length of about 10 cm or greater, wherein the third outlet is adjacent to the first outlet and aligned substantially parallel to the first outlet;
- wherein, the heated and humidified breathing gas mixes with the aerosolized medicament after exiting the nasal cannula.
A respiratory therapy system for delivering humidified breathing gas and nebulized medication, the system comprising:
- a nasal cannula including:
- a first prong having a first outlet and a longitudinal axis;
- a second prong having a second outlet;
- a first medicament outlet disposed adjacent to the first prong and arranged to pass aerosolized medicament substantially parallel to the longitudinal axis;
- a first tube in fluid communication with the first and second prongs;
- and a second tube having a second length, wherein the first tube is not in fluid communication with the second tube along the length of the first tube;
- and
- a nebulizer in fluid communication with the first medicament outlet through the second tube.
