<p>PROBLEM TO BE SOLVED: To provide an inhalator which is simple and reliable in use with a powder substance and gives the powder excellent dispersing properties so that the powder can easily reach the lung. SOLUTION: A tubular member has a first opening part 3, through which air is sucked, on one end. A chamber 5 has a hole 4 for guiding air into inside. When air is sucked through the first opening part 3, the air goes through the hole 4 and moves toward the first opening part 3 in an eddy current. A single restriction part 10 is placed in between the opening part 3 and the hole 4 to maintain or increase the eddy current effect of the air. The powdered substance 8 in the chamber 5 is blown up by the eddy current air in the chamber 5 to be dispersed uniformly and finely by the eddy current effect of the air. The effect is increased by adding a movable element 6 such as a ball, etc., inside the chamber 5 and/or equipping a central core element inside the chamber 5.</p> |
