Abstract

A nasal delivery device and a method of delivering substance to a nasal airway of a subject can be used for mass treatment, especially mass vaccination. The delivery device can include an interface unit, as a replaceable unit, having at least one nosepiece unit for fitting to a respective nostril of a subject, a nozzle from which substance is in use delivered, and at least one delivery unit having a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit. The delivery device can also include an actuation unit for actuating the at least one delivery unit of the interface unit.

Claims

exact text as granted — not AI-modified
1 . (canceled) 
     
     
         2 . An interface unit comprising:
 a nosepiece for fitting to a first nostril of a subject, the nosepiece comprising a nozzle for delivery of a substance to the subject; and   a substance supply unit from which the substance is delivered to the nozzle;   wherein the interface unit is configured to be clipped to an actuation unit.   
     
     
         3 . The interface unit of  claim 2 , wherein the interface unit is replaceable. 
     
     
         4 . The interface unit of  claim 2 , wherein the substance is a powder. 
     
     
         5 . The interface unit of  claim 2 , wherein the substance is a liquid. 
     
     
         6 . The interface unit of  claim 2 , wherein the nosepiece comprises a cuff member for positioning the nosepiece within the first nostril of the subject. 
     
     
         7 . The interface unit of  claim 2 , wherein the nozzle is configured to generate an aerosol spray. 
     
     
         8 . An interface unit comprising:
 a nosepiece for fitting to a first nostril of a subject, the nosepiece comprising a nozzle for delivery of a substance to the subject; and   a substance supply unit from which the substance is delivered to the nozzle;   wherein the interface unit is configured to be slidingly attached to an actuation unit.   
     
     
         9 . The interface unit of  claim 8 , wherein the interface unit is replaceable. 
     
     
         10 . The interface unit of  claim 8 , wherein the substance is a powder. 
     
     
         11 . The interface unit of  claim 8 , wherein the substance is a liquid. 
     
     
         12 . The interface unit of  claim 8 , wherein the nosepiece comprises a cuff member for positioning the nosepiece within the first nostril of the subject. 
     
     
         13 . The interface unit of  claim 8 , wherein the nozzle is configured to generate an aerosol spray. 
     
     
         14 . An interface unit comprising:
 a nosepiece for fitting to a first nostril of a subject, the nosepiece comprising a nozzle for delivery of a substance to the subject; and   a substance supply unit from which the substance is delivered to the nozzle, the substance supply unit containing a metered dose of the substance.   
     
     
         15 . The interface unit of  claim 14 , wherein the interface unit is replaceable. 
     
     
         16 . The interface unit of  claim 14 , wherein the interface unit is configured to be slidingly attached to an actuation unit. 
     
     
         17 . The interface unit of  claim 14 , wherein the interface unit is configured to be clipped to an actuation unit. 
     
     
         18 . The interface unit of  claim 14 , wherein the substance is a powder. 
     
     
         19 . The interface unit of  claim 14 , wherein the substance is a liquid. 
     
     
         20 . The interface unit of  claim 14 , wherein the nosepiece comprises a cuff member for positioning the nosepiece within the first nostril of the subject. 
     
     
         21 . The interface unit of  claim 14 , wherein the nozzle is configured to generate an aerosol spray.
