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 A respiratory system component comprising: an inspiratory tube; an expiratory tube; a patient interface configured for delivery of respiratory gases and aerosolized substances to a patient; an adaptor joining the inspiratory tube, the expiratory tube, and the patient interface, the adaptor including a sealing portion and a coupling surface, wherein the sealing portion is positioned at a proximal end of the adaptor and the patient interface is positioned at a distal end of the adaptor, and wherein the inspiratory tube is positioned proximal to the expiratory tube; a removable nozzle configured to be removable when the respiratory system is in operation; a valve, included in the sealing portion; and wherein the removable nozzle is inserted into the adaptor through the valve, wherein an end of the removable nozzle is closer to the expiratory tube or the patient interface than the inspiratory tube, and wherein the valve is configured to seal the sealing portion when the removable nozzle is removed from the sealing portion. ### Claim 2 (depends on 1) The respiratory system of claim 1 wherein the removable nozzle is configured to be in fluid connection with a delivery device that provides an aerosolised substance. ### Claim 3 (depends on 2) The respiratory system of claim 2 wherein the delivery device is a nebuliser, a capillary aerosol generator, or a metered dose inhaler. ### Claim 4 (depends on 1) The respiratory system of claim 1 wherein the valve is self-sealing. ### Claim 5 (depends on 1) The respiratory system of claim 1 wherein the valve is a duckbill valve or a slit valve. ### Claim 6 (depends on 1) The respiratory system of claim 1 wherein the patient interface comprises nasal prongs that are removably attachable to the adaptor. ### Claim 7 (depends on 1) The respiratory system of claim 1 wherein the removable nozzle is fluidly connected with the patient interface such that deposition within the adaptor of an aerosolised substance delivered through the removable nozzle is reduced. ### Claim 8 (depends on 7) The respiratory system of claim 7 wherein a distance between the removable nozzle and the patient interface is less than about 10 mm. ### Claim 9 (depends on 7) The respiratory system of claim 7 wherein a distance between the removable nozzle and the patient interface is less than about 5 mm. ### Claim 10 (depends on 2) The respiratory system of claim 2 wherein the removable nozzle is configured to be connected to the delivery device through a tube. ### Claim 11 (depends on 10) The respiratory system of claim 10 wherein the tube is configured to allow the delivery device to be removable from the removable nozzle. ### Claim 12 (depends on 1) The respiratory system of claim 1 wherein the removable nozzle comprises a ledge, the removable nozzle being configured such that, when inserted into the adaptor, at least a portion of the ledge is in contact with a portion of the adaptor. ### Claim 13 (depends on 1) The respiratory system of claim 1 further comprising a pressure port. ### Claim 14 (depends on 1) The respiratory system of claim 1 wherein the patient interface comprises a mask or nasal prongs. ### Claim 15 A respiratory system component comprising: an inspiratory tube; an expiratory tube; a patient interface configured for delivery of respiratory gases and aerosolised substances to a patient; an adaptor joining the inspiratory tube, the expiratory tube, and the patient interface; a removable nozzle comprising a ledge, the removable nozzle comprising a first end and a second end, wherein the second end of the removable nozzle is closer to the expiratory tube than the inspiratory tube, and wherein the ledge is external to the adaptor and is configured to allow the first end of the removable nozzle to extend from the adaptor; and a valve. ### Claim 16 (depends on 15) The respiratory system of claim 15, wherein the ledge is configured to limit insertion of the removable nozzle. ### Claim 17 (depends on 15) The respiratory system of claim 15, wherein the ledge is configured to rest on the sealing portion. ### Claim 18 (depends on 15) The respiratory system of claim 15, wherein the removable nozzle is configured to couple with a tube. ### Claim 19 A respiratory system component comprising: an inspiratory tube; an expiratory tube; a patient interface configured for delivery of respiratory gases and aerosolised substances to a patient; an adaptor joining the inspiratory tube, the expiratory tube, and the patient interface, the adaptor including a sealing portion; a removable nozzle comprising a ledge, the removable nozzle comprising a first end and a second end, wherein the ledge is configured to rest on the sealing portion and limit insertion of the removable nozzle within the sealing portion; a valve, included in the sealing portion; and wherein the removable nozzle is removably insertable into the adaptor through the valve such that the second end of the removable nozzle is closer to the expiratory tube and the patient interface than the inspiratory tube. ### Claim 20 (depends on 15) The respiratory system of claim 15, wherein the removable nozzle is removably coupled to a medicament delivery device. ### Claim 21 (depends on 19) The respiratory system of claim 19, wherein the ledge is external to the adaptor. ### Claim 22 (depends on 19) The respiratory system of claim 19, wherein the ledge is configured to allow a top end of the removable nozzle to extend from the adaptor. ### Claim 23 (depends on 19) The respiratory system of claim 19, wherein the removable nozzle is configured to couple with a tube. ### Claim 24 (depends on 19) The respiratory system of claim 19, wherein the removable nozzle is removably coupled to a medicament delivery device.
