Abstract: Disclosed is an end treatment, end structure, or end portion for a nasal dosing device. More particularly, the invention comprises a nasal insert tube for a nasal dosing device. The nasal insert tube is constructed having an outer surface with at least two levels thereby forming a hub. The nasal insert tube has a blunt dispensing end with at least one ejection port that is positioned substantially perpendicularly to the longitudinal axis of the nasal insert tube. Further, the distance from the at least one ejection port to the hub substantially matches a preferred distance from the outer opening of the nasal passage (i.e. the nares) to a location inside the nasal passage shown to augment the effectiveness of nasally administered medicine. For infants, the preferred distance is approximately 1 cm. The invention may be incorporated within in several alternate embodiments.

Abstract: Fire simulating apparatus includes a random number generator, a digital-to-analog converter for converting the output of the random number generator to an analog signal, a lamp coupled to a power source, a switching device coupled in series with the lamp and power source, and a control circuit for controlling the conductivity of the switching device in accordance with the magnitude of the analog signal.
