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 includes 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 also includes an actuation unit for actuating the at least one delivery unit of the interface unit.
Claims57
A nasal delivery device for delivering substance to a nasal airway of a subject, comprising:
- a plurality of interface units attached to a support, each interface unit comprising (i) at least one nosepiece unit for fitting to a respective nostril of a subject and comprising a nozzle from which substance is in use delivered, and (ii) at least one delivery unit comprising a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit;
- and
- an actuation unit to which the interface units are successively attached for actuating the at least one delivery unit of each respective interface unit, the actuation unit comprising an advance mechanism configured to automatically or semi-automatically advance each interface unit in turn to a position with the actuation unit, whereby the at least one delivery unit is in a position to be actuated to deliver substance to the nozzle.
A nasal delivery device for delivering substance to a nasal airway of a subject, comprising:
- a plurality of interface units attached to a belt, each interface unit comprising (i) at least one nosepiece unit for fitting to a respective nostril of a subject and comprising a nozzle from which substance is in use delivered, and (ii) at least one delivery unit comprising a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit;
- and
- an actuation unit to which the interface units are successively positioned for actuating the at least one delivery unit of each respective interface unit, wherein the actuation unit is configured to provide the interface units successively thereto through use of the belt as a guide.
A nasal delivery device for delivering substance to a nasal airway of a subject, comprising:
- a plurality of interface units attached to a support, each interface unit comprising (i) at least one nosepiece unit for fitting to a respective nostril of a subject and comprising a nozzle from which substance is in use delivered, (ii) at least one delivery unit comprising a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit, and (iii) a mouthpiece into which the subject in use exhales;
- and
- an actuation unit to which the interface units are successively positioned for actuating the at least one delivery unit of each respective interface unit.
A nasal delivery device for delivering substance to a nasal airway of a subject, comprising:
- a plurality of interface units attached to a support, each interface unit comprising (i) at least one nosepiece unit for fitting to a respective nostril of a subject and comprising a nozzle from which substance is in use delivered, and (ii) at least one delivery unit comprising a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit;
- and
- an actuation unit to which the interface units are successively positioned for actuating the at least one delivery unit of each respective interface unit;
- wherein the at least one delivery unit is actuated in response to exhalation by the subject.
A nasal delivery device for delivering substance to a nasal airway of a subject, comprising:
- a plurality of interface units attached to a support, each interface unit comprising (i) first and second nosepiece units for fitting to respective nostrils of the subject, each nosepiece unit comprising a nozzle from which substance is in use delivered, and (ii) first and second delivery units, each comprising a substance supply unit for delivering substance through the respective nosepiece unit;
- and
- an actuation unit to which the interface units are successively attached for actuating the first and second delivery units in succession such that substance is first delivered into one nasal cavity and subsequently into the other nasal cavity.
