<p>A capsule holder 2 is provided with a capsule accommodating hole 5 and a supplying valve 9. A pump section 11 having a sucking valve 12 is provided at the air inflow-side of the capsule holder 2, while a medicine spraying section 15 having two medicine passages 20, 20 diverging from the capsule accommodating hole 5 and spraying holes 21, 21 is provided at the air outflow-side of the capsule holder 2. A perforator 25 is housed in the medicine spraying section 15. A capsule is accommodated in the capsule accommodating hole 5, and through-holes are formed in the capsule with the perforator 25, upon which the medicine within the capsule can be administered to the left and right nasal cavities of a patient under the action of air from the pump section 11. Additionally, a spreading chamber 63 is provided to be formed at the downstream side of the capsule accommodating hole 5. Air and the medicine from the capsule can be effectively mixed with each other by virtue of this spreading chamber 63, so that the medicine can be administered to the left and right nasal cavities of the patient at a uniform mixing degree. <IMAGE></p> |
