  • Patent number: 6811543
    Abstract: 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.
