Abstract
A capsule holder is provided with a capsule accommodating hole and a supplying valve. A pump section having a sucking valve is provided at the air inflow-side of the capsule holder, while a medicine spraying section having two medicine passages diverging from the capsule accommodating hole and spraying holes is provided at the air outflow-side of the capsule holder. A perforator is housed in the medicine spraying section. A capsule is accommodated in the capsule accommodating hole, and through-holes are formed in the capsule with the perforator, 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. Additionally, a spreading chamber is provided to be formed at the downstream side of the capsule accommodating hole. Air and the medicine from the capsule can be effectively mixed with each other by virtue of this spreading chamber, so that the medicine can be administered to the left and right nasal cavities of the patient at a uniform mixing degree.
