There is an "inhaler" according to the invention of No. 343. The inhaler main body 1100 has a concave lower housing 101 having a convex portion 101a in the center of an inner bottom through which an air inlet 103 passes vertically, and a mouthpiece 1 having a cylindrical portion 102a loosely fitted in the lower housing 101.
02, the lower end of the cylindrical portion 102a continuous with the mouthpiece 102 is loosely fitted to the convex portion 101a,
The space above the projection 101a is a capsule chamber 106.

Then, the capsule K is loosely fitted to the lower housing 101 as described above, and the mouthpiece 102 is compressed against the spring 109 so that the puncture needle 111 is formed as described above. The capsule K in the capsule chamber 106 can be opened by pushing the button 104 against the spring 109 by aligning the through hole 112 with the through hole 112.

The hemispherical cap is not damaged. Then, after opening the capsule K, the finger pushing the button 104 is released, and after the compression of the mouthpiece 102 is released, when the user holds the mouthpiece 102 and sucks it, the capsule K is air-flowed. The valve 103 vibrates up and down while acting as a valve that closes or opens the inlet 103, so that the powder medicine in the capsule K can be scattered from the opening portion, and can be inhaled through the flow paths 107 and 108 in the air flow. ing. The flow path 107 has a rib shape, and is configured so as not to block the flow path when the capsule K rises.

No. 97, there is a "powder drug inhaler". It comprises a capsule chamber 202 in which the powdered pharmaceutical capsule 224 can be stored rotatably about its short axis. Then, the capsule 224 is rotated by the air supply port 212 flowing along the side surface of the capsule chamber 202, and the powdered medicine is scattered and mixed by the centrifugal force to form a suction airflow.

１２を一致させねばならなかったからである。However, in the conventional inhaler disclosed in Japanese Patent Publication No. Hei 5-79343, the operations of loading, opening and suctioning the capsule are troublesome. That is, after the mouthpiece 102 is removed from the lower housing 101, the capsule K must be stored in the cylindrical portion 102a, and the spring 109 may be lost when the capsule K is removed. In addition, when the mouthpiece 102 is loosely fitted into the lower housing 101 in a predetermined manner, the lower end of the mouthpiece 102 has to be well fitted into a convex portion provided on the inner bottom surface of the lower housing 101, and the capsule K is opened. Pierced needle 111 and through hole 1
This is because 12 had to be matched.

もない。In addition, the above-mentioned inhaler has a great disadvantage that the powdered medicine in the capsule is not uniformly and rapidly injected at the time of inhalation. That is, the vertical vibration of the capsule K is intermittent, and it is difficult to uniformly disperse the powder. It goes without saying that such a non-uniform mixture flow is therapeutically undesirable.

It was difficult to form, and sometimes it became clumpy.

The present application suction device 100 includes an upper housing 4 having a suction port 3,
A lower housing 2 having a bottomed cylindrical capsule chamber 1 capable of vertically storing a powdered pharmaceutical capsule 7 is connected via a hinge portion 5, and a relatively light touch is provided at a portion opposed to the hinge portion 5. A locking means (for example, comprising a claw piece and its engaging groove) 6 is provided which can be disengaged with a click feeling.

原位置へと復帰できるようになっている。On the outside of the lower housing 2, there is provided a piercing means 10 which penetrates the side wall of the capsule chamber 1 and opens the capsule 7 in the chamber. The piercing means 10 is urged outward by the action of a spring 11 loaded between the piercing means 10 and the side wall of the capsule chamber 1.
The puncture needle 9 implanted on the inner surface penetrates the side wall of the capsule chamber 1 so that the capsule 7 in the chamber can be opened. Thus, the perforating means 10 is opened after opening.
If the pressing force of the finger is released from zero, the spring 11 can return to the original position by the action of the spring 11.

室１の側壁からカプセル室内に注入されることとなる。An air intake 12 is provided on the lower surface of the lower housing 2. The air inlet 12 is formed in a mesh shape, and is configured so that a large amount of air can be taken in at once. The side wall of the capsule chamber 1 is provided with one or a plurality of (four, but not limited to, four at equal positions in the drawing) air passages 13 oriented in the tangential direction. That is, the air taken into the lower housing 2 from the air intake port 12 is injected into the capsule chamber from the side wall of the capsule chamber 1 through the ventilation path 13.

Wherein the capsule is vertically housed in the capsule chamber.
The portion corresponding to the vicinity of the abdomen is provided so as to be directed in the tangential direction because the main direction of ventilation (tangential direction 7T) is the eddy current in the small space S between the capsule chamber 1 and the capsule 7 in the direction of the arrow. N to make N and capsules inside capsule room
Enable efficient rotation at high speed while standing upright
That's why . That is, as shown in FIG. 2, the central axis J of the vortex N is coincident with the longitudinal central axis of the capsule chamber 1 (the central axis of the capsule 7) J ', and the capsule 7 is made substantially upright. > Acts as a high-speed rotation force. Accordingly, the powdered medicine in the capsule is vigorously dispersed from the opened mouth and instantaneously uniformly mixed with the airflow to flow toward the suction port 3.

However, at this time, there is a slight click feeling, so that the engagement is ensured. I understand. Thereafter, if the punching means 10 provided on the outside of the lower housing 2 is strongly pressed by a finger, the capsule 7 is opened through the side wall of the capsule chamber 1. Completion of the opening can be sensed by transmitting the feeling at the moment when the capsule 1 is broken by the puncture needle 9 to the finger.
