The proximal end side is fitted and fixed to the drug dispenser body 1 so that the proximal end side opens to the bottom part 7A of the capsule housing part 7 and the distal end side opens to the vicinity of the upstream end 4A of the tapered part 4 of the inhalation passage 2. Further, the tip end side of the suction pipe 9 projects from the inner surface of the suction passage 2 and
The tip is an inclined opening 9A that is inclined so that the opening area increases toward the downstream side.
A granular drug as a drug powder that is sucked out by A through the suction pipe 9 is efficiently mixed into the intake air flow.

【００２５】本実施例による吸入式投薬器は上述の如き
構成を有するもので、次に、吸入式投薬器を用いた投薬
手順について説明する。The inhalation-type medication device according to the present embodiment has the above-mentioned structure. Next, the administration procedure using the inhalation-type medication device will be described.
【００２６】まず、カプセル１０に長手方向に貫通する
一対の穴部Ｈ，Ｈを形成し、このカプセル１０をカプセ
ル収容部７内に底部７Ａまで挿入する。First, a pair of holes H, H penetrating in the longitudinal direction are formed in the capsule 10, and the capsule 10 is inserted into the capsule housing 7 up to the bottom 7A.
【００２７】次に、カプセル１０をカプセル収容部７に

ル収容部７内の空気を吸引するようになる。Next, when the patient holds the capsule 10 in the capsule accommodating portion 7 and holds the mouth by the mouth and breathes lightly, the outside air is sucked through the suction passage 2. At this time, the flow velocity of the air (intake air flow) flowing into the intake passage 2 is increased by the throttle portion 3 and the taper portion 4
As a result, the flow velocity is gradually decelerated and flows into the lungs of the patient, and a suction force (negative pressure) is generated in the suction pipe 9 to suck the air in the capsule housing portion 7.
【００２８】これにより、カプセル収容部７内に収容さ

３から流入する空気流に効果的に混入し、空気流と共に
患者の肺内に吸込まれるから、患者は、軽く息を吸込む
だけで顆粒状薬品を肺内に吸入することができる。Therefore, the granular medicine sucked out through the suction pipe 9 is effectively mixed with the air flow coming from the throttle portion 3 by the inclined opening 9A of the suction pipe 9, and the lung medicine of the patient is mixed with the air flow. As it is inhaled, the patient can inhale the granular drug into the lungs with only a slight inspiration.

できる。When inhaling the above-mentioned granular medicine,
The airflow flowing from the throttle portion 3 is supplied to the downstream end 3A of the throttle portion 3.
Since the stepped portion 6 formed in the above-described structure is separated from the inner surface of the taper portion 4 or the like, it is possible to prevent the granular medicine mixed in the air flow from adhering to the taper portion 4 or the like.

患者の負担を大幅に低減することができる。Thus, according to this embodiment, the suction passage 2
Thereby effectively increasing the flow velocity of the air inhaled by the patient to generate suction force in the suction pipe 9, and the granular drug in the capsule 10 is sucked into the suction passage 2 through the suction pipe 9 to be sucked into the lungs together with the air flow. Since it is designed to be inhaled, it is possible to effectively inhale the granular drug simply by inhaling,
The burden on the patient can be significantly reduced.

ることができる。Further, a pair of holes H penetrating the capsule 10 are formed, and an air flow passing through the inside of the capsule 10 is generated by the suction force of the suction tube 9, so that the granular drug inside can be sucked out by this air flow. Therefore, compared with the release of the drug by the centrifugal force described in the prior art, the capsule 10
The granular drug in the capsule 10 can be positively sucked out, and the granular drug in the capsule 10 can be efficiently inhaled by one inhalation operation.

作業を簡略化でき、取扱いを容易にすることができる。Further, a step portion 6 is provided at the downstream end 3A of the throttle portion 3.
Since the air flow that flows in through the throttle portion 3 is separated from the inner surface of the taper portion 4 by providing
It is possible to reliably prevent the granular drug mixed in the air flow from adhering to the taper portion 4 and the like, efficiently suck the granular drug mixed in the air flow, and simplify the cleaning work of the inhalation-type medication device. And can be handled easily.

製造コストの低減を図ることができる。Furthermore, since the granular drug is sucked out by the Venturi action by the suction passage 2, there is no need for a capsule holder or a screw as in the inhalation-type medication device described in the prior art, and the number of parts is small. As a result, assembly workability and manufacturing cost can be reduced.
