【発明の詳細な説明】本発明は粉末剤用吸入器に係り、その粉末剤は呼吸用空
気の入口および出口を有する吸入器ケースの中−にそう
人可能なカプセルの中に収容される。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inhaler for a powder, the powder being contained in a removable capsule within an inhaler case having an inlet and an outlet for breathing air.
たとえば医療に適用されるこの種の吸入器は既知のもの
である。Inhalers of this type for medical applications are known, for example.
カプセルのそう人によって、吸入せられるべき正確に調
合された薬剤の量がこの器具の中に実在し、そのためこ
れを要する場合、たとえば急性ぜんそく発作中有害な過
剰の調剤が吸入され得ない利点がある。The advantage is that a precisely formulated amount of the drug to be inhaled by the person in charge of the capsule is present in this device, so that when this is required, a harmful excess of the drug cannot be inhaled, for example during an acute asthma attack. be.
さらにこれは軽便で容易にポケットに収め得る。Furthermore, it is lightweight and can easily be stored in a pocket.
上述の種類の吸入器は、カプセルが、本器に配備される
プロペラ羽根によって空気流の本器に設けられる吸口を
経て吸引されるときぐらぐらする回転運動をするような
回転し得るよう取付けられる円筒形スリーブの中に押し
込められるように作られている。An inhaler of the type described above consists of a cylinder mounted in such a way that the capsule can be rotated in such a way that the capsule undergoes a wobbling rotational movement when drawn through a mouthpiece provided in the main body of the air stream by means of propeller blades provided in the main body. It is made to be pushed into a shaped sleeve.
すでに穴をあけられたカプセルの中にある粉末剤は乱気
流によって付随的にカプセルから引上げられ、そこで、
吸入された空気とともに吸口を経て患者の口に入り込む
、本器の欠点は、各カプセルをそう人するとき本器は３
部分に分解せねばならずかつおよそ週に１回は手入、す
なわち分解、掃除、油差しをせねばならぬことである。The powder already in the pierced capsule is concomitantly pulled up from the capsule by the turbulence, where it is
The drawback of this device is that the inhaled air enters the patient's mouth through the mouthpiece.
It must be disassembled into parts and must be maintained, ie disassembled, cleaned and oiled, approximately once a week.
さらにその信頼性は不十分であって、そのため製造業者
は代替器を常時用意することを勧める。Moreover, their reliability is inadequate, so manufacturers recommend that replacements be kept on hand at all times.
本発明の目的は、これらの欠点をなくシ、簡単にして、
確実に操作され、かつ軽便にして、伺ら保守を要せずし
かも信頼し得る吸入器を得るにある。The purpose of the invention is to eliminate these drawbacks, simplify and
To obtain an inhaler that can be operated reliably, is lightweight, requires no maintenance, and is reliable.
本発明によればこの問題は、カプセル受容空所カケース
の円周に位置し、円周に開口する側面を有し、その上に
可動式に配備される外囲が設けられ、これは充填しおよ
び空虚にする位置ではカプセル受容空所をおおわず、そ
の他の位置ではこれをおおう。According to the invention, this problem is solved by providing a capsule-receiving cavity with a movably disposed outer envelope located on the circumference of the case and having side surfaces opening to the circumference, which is not filled. and do not cover the capsule-receiving cavity in the emptying position and cover it in other positions.
この外囲は、回転するよう配備され、カプセルが横断す
る通路として作用する穴を有する。This envelope is arranged to rotate and has holes that act as passages for the capsule to traverse.
この外囲はそれの切欠きに対し長さ方向に移動するよう
に案内される止め材によって充填しおよび空虚にする位
置に止められる。The envelope is held in the filling and emptying position by a stop that is guided to move longitudinally relative to the notch in the envelope.
この止めピンには受容空所内にあるカプセルに対する放
出器が結合されているが、それは、カプセルをばねの力
のもとに受容空所にそう人可能であり同時に止めピンを
外囲の穴の中に動かすようになっている。An ejector for the capsule located in the receiving cavity is coupled to this retaining pin, which allows the capsule to be placed into the receiving cavity under the force of a spring and at the same time allows the retaining pin to be inserted into the outer hole. It is designed to be moved inside.
カプセルを受容空所に押しつけている間放出器および止
めピンはケースの内側に押され従ってケースは動き得る
ようになる。While pressing the capsule into the receiving cavity, the emitter and the locking pin are pushed inside the case so that the case can move.
そこでばねは自動的に外囲を遊体位置に動かす。The spring then automatically moves the envelope to the free position.
外囲にはたとえば２個の小さい刃の形をした、カプセル
に穴をあける装置が設けられ、これは前述のばねに反し
て作用する力のもとでカプセル受容空所の中に押される
。The outer envelope is provided with a capsule-piercing device, for example in the form of two small blades, which is pushed into the capsule-receiving cavity under a force acting against the aforementioned spring.
外囲は種々の形たとえば本器を一部囲む円筒形スＩＪ−
ブ、すべり材又は取外し得る帽子のように作られてよい
。The outer enclosure can be of various shapes, such as a cylindrical space that partially surrounds the device.
It may be made like a hat, a slip, or a removable cap.
外囲は透明に作られ、そのため新しいまだ穴のあけてな
いカプセルがそう人されたか否かを示すために刃および
カプセルは常に見えるようになっている。The envelope is made transparent so that the blade and capsule are always visible to indicate whether a new, unpierced capsule has been tampered with or not.
そこで本発明によれば粉末剤用吸入器が得られ、これは
、呼吸雨空器を通す入口および出口を有する吸入器ケー
スと、前記粉末剤を包含するカプセルをそう人し得るよ
う受けるための前記ケースの外周に形成される受容空所
と、本器の外囲部分が前記受容空所のカプセルを封じ込
める第１の位置および前記外囲部分が前記受容空所内の
カプセルをおおわずに、これを取外し交換し得る第２の
位置の間を吸入器のケースと相対的に動くよう前記外囲
部分を前記ケースに取付ける装置を含む。According to the invention, therefore, there is provided an inhaler for a powder, which comprises an inhaler case having an inlet and an outlet through which a respiratory vent is passed, and an inhaler case for receiving a capsule containing said powder so as to be capable of receiving said powder. a receiving cavity formed on the outer periphery of the case, a first position in which the outer part of the device encloses the capsule in said receiving cavity, and said outer part does not cover the capsule in said receiving cavity; A device is included for attaching the enclosure portion to the inhaler case for movement relative to the inhaler case between removable and replaceable second positions.
本発明の長所は、前記ケースの円周にあるカプセル受容
空所が取外し可能な外囲と組合って協力する結果、新ら
しいカプセルは前記ケースを取外すことなくそう人し得
ることにある。An advantage of the invention is that a capsule receiving cavity on the circumference of the case cooperates in combination with a removable envelope so that a new capsule can be installed without removing the case.
外囲のばね装置は、外囲を自動的に遊体位置に動かしよ
って既知の方式に存在する開放位置と遊休又は作動位置
との間にある混乱を解消する効果がある。The spring arrangement of the envelope has the advantage of automatically moving the envelope into the idle position thereby eliminating the confusion that exists in known systems between the open position and the idle or activated position.
ばねの負荷を受けるように配備される前記放出器は本器
の取扱いを非常に簡単にする。The ejector, which is arranged in a spring-loaded manner, greatly simplifies handling of the device.
タービル羽根車の省略は本器の操作を簡単にし、かつそ
の信頼性を改善する。The omission of the turbil impeller simplifies the operation of the instrument and improves its reliability.
本発明は付図を参照して行われる下記説明から一層よく
理解されるであろう。The invention will be better understood from the following description with reference to the accompanying drawings.
付図を参照すれば、吸入器は円筒形ケース２を含みその
一端に吸口１７を備える。Referring to the accompanying drawings, the inhaler includes a cylindrical case 2 with a mouthpiece 17 at one end thereof.
外囲３の穴４はばね１６の弾力に反して充填しおよび空
虚にする位置にもたらされる。The hole 4 in the envelope 3 is brought into a filling and emptying position against the elasticity of the spring 16.
そこでケースの穴Ｔの中を案内されかつ放出器１０に結
合される止めピン６は今１つのばね９の弾力によってそ
のとき利用し得る外囲３の切欠き８の中に押され外囲を
動かぬようにする。The locking pin 6, which is now guided in the hole T in the case and connected to the emitter 10, is now pressed by the elasticity of one spring 9 into the then available cutout 8 of the envelope 3, and presses the envelope. Try not to move.
この状態でカプセル１１は放出器１０と結合するピンが
同時に解放されるように吸入器の受容空所１の中で、そ

にその両端に近く２個の小孔１３をあける。By moving the envelope 3 in the opposite direction from the filling and emptying positions, the envelope 3 is fixed and the case groove 1
A cutter with two small blades 12 guided in 8 engages the receiving cavity 1 and a capsule 11 located therein.
Two small holes 13 are made near both ends of the hole.
円周に沿って設けられるみぞ１８の中を動き得る刃１２
は同時に、外囲として構成されるケースの円筒形スリー
ブに対する軸方向のささえ材として作用する。Blade 12 movable in a groove 18 provided along the circumference
at the same time acts as an axial support for the cylindrical sleeve of the case, which is configured as an envelope.
吸入器の穴あけ位置は第４図に示す。The location of the holes in the inhaler is shown in Figure 4.
両側に作動するばね１６の弾力により外囲３は解放され
たあと遊休および作動位置に自動的に動かされる。Due to the elasticity of the springs 16 acting on both sides, the envelope 3 is automatically moved into the idle and active position after being released.
吸入中カプセル１１の中の粉末剤は穴１３のため第１図
に示すように吸口１７．受容空所１に接続する入口１４
および吸口１７に向って開口する出口１５を経て口内に
吸込まれる。During inhalation, the powder in the capsule 11 passes through the mouthpiece 17 due to the hole 13, as shown in FIG. Inlet 14 connecting to receiving cavity 1
It is then sucked into the mouth through the outlet 15 which opens toward the suction port 17.
空虚になったカプセル１１を取出すには、外囲３をばね
１６の弾力に反して充填しおよび空虚にする位置をもた
