The adaptor is lightweight with a small footprint to increase patient comfort. The adaptor has a nozzle and a sealing mechanism to maintain pressure therein regardless of whether the nozzle is inserted into the adaptor. The adaptor is configured to connect to medical tubing and a medicament delivery device. ## Claims ### Claim 1 An adaptor for medicament delivery comprising: a tubular body having a first end and a second end, wherein the tubular body comprises: an inlet tube having an inlet port at the first end and an outlet at the second end, wherein the inlet port is configured to be connected to an inspiratory conduit for receiving a flow of gases, an outlet tube adjacent to the inlet tube having an outlet port at the first end and an inlet at the second end, wherein the outlet port is configured to be connected to an expiratory conduit for dispensing the flow of gases, and a surfactant delivery tube adjacent to a portion of at least one of the inlet tube and the outlet tube, wherein the surfactant delivery tube comprises an inlet port at the first end and an outlet at a second end, wherein the inlet port is configured to connect to a source of medicament; a housing having a first end and a second end, wherein the first end of the housing is attached to the second end of the tubular body; and a patient interface configured to be connected to the second end of the housing, wherein the patient interface is in fluid communication with an airway of a patient. ### Claim 2 (depends on 1) The adaptor of claim 1, wherein the housing is permanently attached to the tubular body. ### Claim 3 (depends on 1) The adaptor of claim 1, wherein the tubular body and the housing comprise a rigid plastic. ### Claim 4 (depends on 1) The adaptor of claim 1, wherein the housing comprises a divider to separate the flow of gases from a flow of medicament. ### Claim 5 (depends on 4) The adaptor of claim 4, wherein at least a portion of the housing is configured to allow the flow of gases to mix with the flow of medicament. ### Claim 6 (depends on 1) The adaptor of claim 1, wherein the flow of medicament comprises an aerosolized surfactant. ### Claim 7 (depends on 4) The adaptor of claim 4, wherein the divider comprises angled sidewalls. ### Claim 8 (depends on 7) The adaptor of claim 7, wherein the divider further comprises a rounded portion connecting the angled sidewalls to improve fluid flow around corners. ### Claim 9 (depends on 4) The adaptor of claim 4, wherein the divider is configured to provide a plurality of fluid entryways into an interior of an undivided portion of the housing. ### Claim 10 (depends on 4) The adaptor of claim 4, wherein the divider comprises straight walls to form rectangular fluid entryways to the interior of the undivided portion of the housing. ### Claim 11 (depends on 1) The adaptor of claim 1, wherein a cross-section of a portion of the housing in fluid communication with the surfactant delivery tube is greater than a cross-section of a portion of the housing in fluid communication with the inlet tube and the outlet tube, and wherein the greater cross-section of the portion of the housing in fluid communication with the surfactant delivery tube is configured to reduce deposition of medicament within the surfactant delivery tube. ### Claim 12 (depends on 1) The adaptor of claim 1, wherein the patient interface comprises a pair of prongs. ### Claim 13 (depends on 12) The adaptor of claim 12, wherein the nasal prongs are sized to fit the nares of the patient. ### Claim 14 (depends on 12) The adaptor of claim 12, wherein the patient interface is configured to interchangeably attach to a plurality of different nasal prong sizes. ### Claim 15 (depends on 1) The adaptor of claim 1, wherein the patient interface is press-fit onto the second end of the housing. ### Claim 16 (depends on 1) The adaptor of claim 1, wherein the patient interface is removably connected to the second end of the housing. ### Claim 17 (depends on 1) The adaptor of claim 1, wherein the tubular body further comprises a pressure port connected to a pressure sensor, wherein the pressure sensor is configured to measure air pressure flowing through the pressure port. ### Claim 18 (depends on 17) The adaptor of claim 17, wherein the tubular body further comprises a pressure tube connected to the housing. ### Claim 19 (depends on 17) The adaptor of claim 17, wherein the pressure port and the inlet port of the surfactant delivery tube are on opposing sides of the adaptor. ### Claim 20 (depends on 1) The adaptor of claim 1 wherein the tubular body comprises an elongated oval cross-section. ### Claim at position 21 -55.
