<p>A distance-adjustable nozzle mechanism 25 is disposed to a passage member 17 to be located at the ejection sides of left and right medicine passages 20, 20. The distance-adjustable nozzle distance 25 includes fitting projection sections 26, 26 formed in the passage member 17, adjustable nozzles 27, 27 which are rotatably and detachably attached to the fitting projection sections 26, and tapered spray holes 28 each of which is in communication with the medicine passage 20 and formed throughout the fitting projection section 26 and the adjustable nozzle 27, in which the axis of the adjustable nozzle 27 is eccentric to a rotational center. Accordingly, when each adjustable nozzle 27 is rotated, the nozzles can approach to or separate from each other by an amount corresponding to the eccentricity relative to the rotational center, so that the nozzle pitch between the respective adjustable nozzles 27 can be easily adjusted in conformity with the distance between the nasal cavities of the patient. Additionally, cleaning can be facilitated by removing each adjustable nozzle 27. <IMAGE></p> |
