Abstract
An adaptor for a respiratory assistance system delivers aerosols to a patient. 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.
Claims24
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.
