成となっている。In this conventional apparatus, a pump portion is provided on the air inlet side of the cylindrical member, and a concave portion into which a capsule is inserted is formed on the air outlet side of the cylindrical member. The capsule housing portion is formed by fitting the distal end portions, and the air introduction passage is formed from the capsule housing portion toward the pump portion. Further, a valve mechanism is provided on the other side of the pump portion, and by the valve mechanism, air is supplied to the capsule housing portion through the air introduction passage when the pump portion is pressed, and air is supplied from the outside when the pump portion returns. It is designed to suck into the pump section. Furthermore, a state in which a cap that fits the cylindrical member and the tip end portion is provided, and a pin that extends in the axial direction is provided in the cap, and the concave portion of the cylindrical member and the tip end portion that has the opening portion are fitted together The capsule is perforated by fitting the cap with.

与することができる。As described in detail above, according to the first aspect of the present invention, the capsule holding portion accommodates the capsule, and after the hole is formed in the capsule, air is supplied into the capsule from the pump portion.
Since the drug in the capsule is supplied to the left and right nasal cavities of the patient from each drug passage of the drug spraying section through the spray port together with the air, the drug is evenly and uniformly applied to the left and right nasal cavities of the patient. It is possible to administer the medication, and it is possible to improve the spraying efficiency by eliminating the trouble of separately administering the medication to the left and right nasal cavities, and to simplify the medication operation of the patient. The air supplied from the air is vigorously circulated while containing the chemicals, whereby the outside air is introduced (sucked) into the respective chemical passages through the external air introduction passages, and the air containing the chemicals and the inner walls of the respective chemical passages are separated from each other. Since the outside air layer is formed by the outside air introduced during the period, the outside air layer can prevent the medicine from adhering to the inner wall of the medicine passage and reliably administer the prescribed amount of medicine to the patient.
