Document Type and Number:
Japanese Patent JP3225966
Kind Code:
B2
Abstract:
The invention concerns an inhaler device (1) having a hollow tubular member (2, 102, 402) connected to a chamber (5, 105, 405). The tubular member has a first opening (3, 103, 203) at one end through which air can be sucked and the chamber (5, 105, 405) has a hole (4, 104, 204) therein for entry of air. When air is sucked through the first opening, air enters the chamber through the hole swirls and moves towards the first opening (3, 103, 203). To maintain or increase the swirling effect of the air a single restriction (10, 110) is arranged between the opening and the hole (4, 104, 204). A powdered substance (8) within the chamber is picked up by the swirling air within the chamber and is uniformly and finely divided by the swirling effect of the air. The effect can be enhanced by adding a movable element (6) such as a ball inside the chamber (5) and/or by providing a central core element (112, 412) inside the chamber.
