Estimating the term…
A device for applying a powdered or particulate substance to a mucous membrane in a nostril comprises a tubular body (10) similar to a drinking straw. The tubular body has opposite end parts forming a mouthpiece (11) and a nasal piece (12) to be inserted between the lips and into the nostril, respectively, of a user. The mouthpiece (11) and the nasal piece (12) are interconnected by a bent or a bendable, preferably corrugated part (13). A dose of a powdered or particulate substance arranged within the tubular body (10) is transferred to the nostril when the user blows into the mouthpiece (11). A part of the mouthpiece is preferably deflated or compresses between a pair of fingers (35) of the user. The compressed part (34) is released when the user has started to blow forcefully into the compressed mouthpiece part which is thereby inflated. It has been found that the user will automatically close the connection between the nostrils and the throat by the uvula when blowing.
A method for introducing a powdered or particulate substance into a nostril of a person, said method comprising
A device for applying a powdered or particulate substance to a mucous membrane within a nostril of a user of the device, said device comprising a tubular body having a mouthpiece at a first end to be inserted between the lips of the user and a nasal piece at an opposite second end to be inserted into the nostril, the tubular body further defining an inner flow passage extending longitudinally between the mouthpiece and the nasal piece, whereby the user may blow into the mouthpiece end of the flow passage and transfer the powdered or particulate substance arranged within the flow passage of the tubular body to the nostril in a dispersed condition.
A device for dispersing a powdered or particulate substance in an airflow, said device comprising a tubular body having a mouthpiece at one end to be inserted between the lips of a user so that the user may blow into or inhale through the mouthpiece end of a flow passage defined within the tubular body and disperse powdered or particulate substance arranged within the flow passage of the tubular body into the air flowing through the flow passage, cross-sectional restriction means being arranged within the flow passage forming at least one cross-sectional restriction, said restriction means being moveable between a first closing or restricting position and a second position in which no or substantially less restriction is defined by the restriction means.
