INTRANASAL MEDICATOR

摘要

An intranasal medicator composed of a capsule holder, a pumping section, and a drug-spraying section. A capsule holder (2) is provided with a capsule pit (5) and a supply valve (9). The holder (2) is connected, on the air inlet side, to a pumping section (11) provided with an intake valve (12) and, on the air outlet side, to a drug-spraying section (15) provided with two drug passages (20 and 20) and two spraying ports (21 and 21) branched from the capsule pit (5). The drug-spraying section (15) has a built-in borer (25). The encapsulated drug can be administered to the nasal cavities of a patient by putting a capsule in the pit (5), boring the capsule with the borer (25), and sending the drug through each spraying port (21) into the nasal cavities by means of the air supplied from the pumping section (11). The medicator is further provided with a diffusion chamber (63) on the downstream side of the pit (5), whereby the drug is efficiently mixed with the air and evenly administered to both cavities through each port (21).
