本発明は、粉末薬剤や粉末サプリメント等の経口粉末を収容した容器の吸入口に装着することで、粉末吸入剤を確実に摂取できるようにするための吸入補助器具に関する。
The present invention relates to an inhalation assisting device for ensuring that a powder inhalant can be ingested by being attached to an inhalation port of a container containing an oral powder such as a powder drug or a powder supplement.
経口吸入により粉末薬剤や粉末サプリメント（以下、これらを総称して「経口粉末」という。）を摂取するために吸入器が用いられている。
一般的な吸入器は、容器内の収容室に収容された経口粉末を吸入口から吸入すると、容器に設けた外気導入口から収容室内に空気が導入され、この空気によって経口粉末が巻き上げられながら吸入口を介して口腔内に移動する仕組みになっている（特許文献１参照）。 Inhalers are used to take powdered drugs and powder supplements (hereinafter collectively referred to as “oral powder”) by oral inhalation.
In a general inhaler, when oral powder stored in a storage chamber in a container is inhaled from the suction port, air is introduced into the storage chamber from an outside air inlet provided in the container, and the oral powder is rolled up by this air. The mechanism moves into the oral cavity through the suction port (see Patent Document 1).

経口粉末を吸入器で摂取する場合、その成否は点滴や内服で摂取する場合と比較して使用者の技量に負うところが大きい。
本願発明者は、粉末の抗インフルエンザ薬の吸入実態を調査し（非特許文献１参照）、以下の課題が存在することを解明した。
（１）一回の吸引では粉末が容器内に残ってしまうことがあり、規定量を吸引し終えるまでに複数回の吸引を要することがある。
（２）９歳以下では約一割が吸入に失敗し、その原因のほとんどが誤って吹込んでしまったことにある。 When ingesting oral powder with an inhaler, the success or failure depends largely on the skill of the user compared to ingestion by infusion or internal use.
The inventor of the present application investigated the actual inhalation of powdered anti-influenza drugs (see Non-Patent Document 1) and clarified that the following problems exist.
(1) A single suction may leave the powder in the container, and a plurality of suctions may be required before the specified amount is sucked.
(2) About 10% of people under the age of 9 failed to inhale, and most of the causes were accidentally inhaled.

上記調査結果を踏まえると、上記特許文献１のような従来技術では以下のような問題がある。
すなわち、一回の吸引後、実際には経口粉末が容器内に残っているにもかかわらず、それを目視で確認することが困難なため、吸引が成功したと誤認識してしまい、摂取量が規定量に満たず充分な効果を得られないおそれがある。 In view of the above investigation results, the conventional technique such as Patent Document 1 has the following problems.
In other words, after a single inhalation, the oral powder actually remains in the container, but it is difficult to visually confirm it, so it is misrecognized that the inhalation was successful, and the intake amount However, there is a possibility that sufficient effects cannot be obtained because the amount is less than the prescribed amount.

本発明は上記問題に鑑み、経口粉末が格納された容器の吸入口に装着することで、容器内の経口粉末を効果的に摂取できる吸入補助器具を提供することを目的とする。
In view of the above problems, an object of the present invention is to provide an inhalation assisting device capable of effectively ingesting an oral powder in a container by being attached to an inhalation port of the container in which the oral powder is stored.
本発明の吸入補助具は、吸入口と、経口粉末を容器内に収容するための収容室と、前記吸入口と前記収容室とを繋ぐ空気流通路と、外気を前記収容室に導入するための外気導入口とを少なくとも備える吸入器に取り付けるものであり、一方の端部に前記吸入口に装着される装着部を備え、他方の端部にマウスピースを備え、内部に吸入時にのみ空気の通過を許容する一方向弁を備える中空部材であり、前記収容室の開口断面積と前記マウスピースの開口断面積とを比較した場合に、前記マウスピースの開口断面積の方が大きいことを特徴とする。
また、前記マウスピースの開口径と前記装着部の開口径とを異ならせることを特徴とする。
また、外周面から径方向外側にのびる鍔部を備えることを特徴とする。
また、前記マウスピースの開口部に異物誤飲防止用のフィルターを備えることを特徴とする。 The inhalation aid of the present invention introduces an intake port, a storage chamber for storing oral powder in a container, an air flow passage connecting the suction port and the storage chamber, and outside air into the storage chamber. The outside air inlet is attached to an inhaler having at least one mounting portion to be attached to the suction port at one end portion, a mouthpiece at the other end portion, and the inside of the inhaler only for inhalation. A hollow member having a one-way valve that allows passage, wherein the opening cross-sectional area of the mouthpiece is larger when the opening cross-sectional area of the storage chamber and the opening cross-sectional area of the mouthpiece are compared.

The mouthpiece has a filter for preventing accidental ingestion of foreign matter.
本発明の吸入補助具の装着部を吸入器の吸入口に取り付けた状態で、使用者がマウスピースを咥えて吸引すると、外気導入口から収容室内に導入された空気によって収容室内の経口粉末が巻き上げられ、空気と共に空気流通路内を移動し、一方向弁を通過してマウスピースから口腔内に至る。
本発明ではマウスピースの開口断面積を収容室の開口断面積よりも大きくしているため、ベンチュリー効果によって、マウスピース内の空気の流速と、収容室内の空気の流速とを比較した場合に、収容室内の空気の流速の方が大きく（速く）なる。
これにより使用者が例えば高齢者、子供、患者等、吸引力が弱い者であっても、収容室内の空気の流速を速めることができる。すなわち、吸引力を高める効果が得られるので、一回の吸引後に経口粉末が容器内に残る量を大幅に削減し、経口粉末を効果的に摂取できる。
また、高齢者や子供等は誤って吸入器内に空気を吹込んでしまうことがあるが、本発明では吸入時にのみ空気の通過を許容する一方向弁を備えるので、誤って空気が吹き込まれた場合には一方向弁が機能し、空気が空気流通路及び収容室内に逆流してしまう事態を未然に防止できる。
また、使用者が幼児の場合には吸入の意味を理解できない、すなわち吸入するためにはどういう動作を行えばよいのかが理解できないことがある。本発明では幼児が吹込み等の吸入以外の誤動作を行った場合には、一方向弁の機能によってマウスピース内を空気が移動しなくなるため、その誤動作を行えなくなる（動作が遮断される）。そして、何度か試行錯誤を繰り返し、正常動作（吸入動作）を行った場合のみ一方向弁の機能によりマウスピース内を空気及び経口粉末が移動し、これらを吸い込むことができるようになるので、幼児は吸入するために必要な動作（吸入）がどういうものかを感覚的に理解できるようになる。
また、マウスピースの開口径と装着部の開口径とを異ならせることによって、使用者が誤ってマウスピースを吸入口に装着してしまう事態を未然に防止できる。
また、鍔部を設けることで、使用者（特に幼児）が吸入補助器具を口の中に入れようとした際に当該鍔部が唇に引っ掛かるため、吸入補助器具を誤飲してしまう事態を防止できる。
また、フィルターを設けることで、万が一、一方向弁が固着箇所から外れてしまった場合でも、フィルターに引っ掛かるので誤飲を防止できる。 When the user holds and sucks the mouthpiece in a state where the mounting portion of the inhaler of the present invention is attached to the suction port of the inhaler, the oral powder in the storage chamber is formed by the air introduced into the storage chamber from the outside air inlet. It is rolled up, moves in the air flow passage with air, passes through the one-way valve, and reaches from the mouthpiece to the oral cavity.
In the present invention, since the opening cross-sectional area of the mouthpiece is larger than the opening cross-sectional area of the storage chamber, when the flow rate of air in the mouthpiece and the flow rate of air in the storage chamber are compared by the venturi effect, The flow velocity of the air in the storage chamber is larger (faster).
Thereby, even if a user is a weak person, such as an elderly person, a child, a patient, etc., the flow velocity of the air in a storage chamber can be increased. That is, since the effect of increasing the suction force can be obtained, the amount of the oral powder remaining in the container after a single suction can be greatly reduced, and the oral powder can be effectively ingested.
In addition, although elderly people and children may inadvertently blow air into the inhaler, the present invention includes a one-way valve that allows the passage of air only during inhalation, so air has been inadvertently blown. In this case, the one-way valve functions to prevent a situation where air flows backward into the air flow passage and the storage chamber.
In addition, when the user is an infant, the meaning of inhalation cannot be understood, that is, what operation should be performed to inhale may not be understood. In the present invention, when an infant performs a malfunction other than inhalation such as blowing, the function of the one-way valve prevents air from moving through the mouthpiece, so that the malfunction cannot be performed (operation is blocked). And, after repeating trial and error several times, only when normal operation (inhalation operation) is performed, the function of the one-way valve allows air and oral powder to move through the mouthpiece, so that they can be inhaled. Infants can understand sensuously what actions (inhalation) are necessary for inhalation.
In addition, by making the opening diameter of the mouthpiece different from the opening diameter of the mounting portion, it is possible to prevent the user from accidentally mounting the mouthpiece on the suction port.
In addition, by providing a buttocks, when the user (especially an infant) tries to put the inhalation aid into the mouth, the buttocks get caught in the lips. Can be prevented.
In addition, by providing a filter, even if the one-way valve is removed from the fixed position, it can be caught by the filter and thus prevent accidental ingestion.

これにより使用者が例えば高齢者、子供、患者等、吸引力が弱い者であっても、収容室内の空気の流速を速めることができる。すなわち、吸引力を高める効果が得られるので、一回の吸引後に経口粉末が容器内に残る量を大幅に削減し、経口粉末を効果的に摂取できる。

In this case, the one-way valve functions to prevent a situation where air flows backward into the air flow passage and the storage chamber.
In addition, when the user is an infant, the meaning of inhalation cannot be understood, that is, what operation should be performed to inhale may not be understood. In the present invention, when an infant performs a malfunction other than inhalation such as blowing, the function of the one-way valve prevents air from moving through the mouthpiece, so that the malfunction cannot be performed (operation is blocked). And, after repeating trial and error several times, only when normal operation (inhalation operation) is performed, the function of the one-way valve allows air and oral powder to move through the mouthpiece, so that they can be inhaled. Infants can understand sensuously what actions (inhalation) are necessary for inhalation.
In addition, by making the opening diameter of the mouthpiece different from the opening diameter of the mounting portion, it is possible to prevent the user from accidentally mounting the mouthpiece on the suction port.
In addition, by providing a buttocks, when the user (especially an infant) tries to put the inhalation aid into the mouth, the buttocks get caught in the lips. Can be prevented.
In addition, by providing a filter, even if the one-way valve is removed from the fixed position, it can be caught by the filter and thus prevent accidental ingestion.

一方向弁４０は装着部２０の内側面に取り付けられる薄い楕円型の部材である。具体的には図２に示すように一方向弁４０の周縁の一部が装着部２０の内側面に固着されており、固着された箇所を支点にして前後方向（空気の移動方向）に揺動できるようになっている。また、装着部２０の内側面であって、一方向弁４０の固着箇所に対向する位置にはストッパー４１が取り付けられている。
The one-way valve 40 is a thin oval member attached to the inner surface of the mounting portion 20. Specifically, as shown in FIG. 2, a part of the periphery of the one-way valve 40 is fixed to the inner surface of the mounting portion 20, and swings in the front-rear direction (air movement direction) with the fixed portion as a fulcrum. It can be moved. Further, a stopper 41 is attached to the inner surface of the mounting portion 20 at a position facing the fixed portion of the one-way valve 40.
図４は吸入補助器具１０を吸入器１００に取り付けた状態の内部構造の一例を示している。
この吸入器１００は、一般的に知られている吸入器と同様に、吸入口１１０と、経口粉末Ｐを容器１２０内に収容するための収容室１３０と、吸入口１１０と収容室１３０とを繋ぐ空気流通路１４０と、外気を収容室１３０に導入するための外気導入口１５０とを少なくとも備えている。 FIG. 4 shows an example of an internal structure in a state where theinhalation assisting device 10 is attached to the inhaler 100.
Theinhaler 100 includes an inhalation port 110, an accommodation chamber 130 for accommodating the oral powder P in the container 120, and the inhalation port 110 and the accommodation chamber 130, similarly to a generally known inhaler. At least an air flow passage 140 to be connected and an outside air inlet 150 for introducing outside air into the storage chamber 130 are provided.
この吸入器１００は、一般的に知られている吸入器と同様に、吸入口１１０と、経口粉末Ｐを容器１２０内に収容するための収容室１３０と、吸入口１１０と収容室１３０とを繋ぐ空気流通路１４０と、外気を収容室１３０に導入するための外気導入口１５０とを少なくとも備えている。 FIG. 4 shows an example of an internal structure in a state where the
The
次に、吸入補助器具１０の使用方法について説明する。
図５（ａ）に示すように、使用者が吸入動作を行った際、すなわち装着部２０側からマウスピース３０側に向かって空気が移動するときには（図中の矢印の向きが空気の流れる方向を指している）、空気の圧力を受けて一方向弁４０はマウスピース３０側に傾く。これによって一方向弁４０と装着部２０の内側面との間に隙間Ｓが生じ、この隙間Ｓを通過して空気及び経口粉末Ｐが口腔内に至る。一方、図５（ｂ）に示すように使用者が誤って吹込み動作を行ってしまった際、すなわちマウスピース３０側から装着部２０側に向かって空気が移動するときには、空気の圧力を受けて一方向弁４０が装着部２０側に傾き、ストッパー４１に衝突することで、一方向弁４０と装着部２０の内側面との間の隙間Ｓが塞がれ、空気及び経口粉末Ｐの逆流及びこれらが外気導入口１５０から外部に噴出する事態を防止するようになっている。 Next, a method for using theinhalation assisting device 10 will be described.
As shown in FIG. 5A, when the user performs an inhalation operation, that is, when air moves from themounting portion 20 side toward the mouthpiece 30 side (the direction of the arrow in the figure is the direction in which the air flows). The one-way valve 40 tilts toward the mouthpiece 30 under the pressure of air. As a result, a gap S is formed between the one-way valve 40 and the inner surface of the mounting portion 20, and air and oral powder P reach the oral cavity through the gap S. On the other hand, as shown in FIG. 5B, when the user accidentally performs the blowing operation, that is, when the air moves from the mouthpiece 30 side toward the mounting portion 20 side, the air pressure is received. When the one-way valve 40 tilts toward the mounting portion 20 and collides with the stopper 41, the gap S between the one-way valve 40 and the inner surface of the mounting portion 20 is closed, and the backflow of air and oral powder P occurs. And these are prevented from being ejected to the outside from the outside air inlet 150.
図５（ａ）に示すように、使用者が吸入動作を行った際、すなわち装着部２０側からマウスピース３０側に向かって空気が移動するときには（図中の矢印の向きが空気の流れる方向を指している）、空気の圧力を受けて一方向弁４０はマウスピース３０側に傾く。これによって一方向弁４０と装着部２０の内側面との間に隙間Ｓが生じ、この隙間Ｓを通過して空気及び経口粉末Ｐが口腔内に至る。一方、図５（ｂ）に示すように使用者が誤って吹込み動作を行ってしまった際、すなわちマウスピース３０側から装着部２０側に向かって空気が移動するときには、空気の圧力を受けて一方向弁４０が装着部２０側に傾き、ストッパー４１に衝突することで、一方向弁４０と装着部２０の内側面との間の隙間Ｓが塞がれ、空気及び経口粉末Ｐの逆流及びこれらが外気導入口１５０から外部に噴出する事態を防止するようになっている。 Next, a method for using the
As shown in FIG. 5A, when the user performs an inhalation operation, that is, when air moves from the
また、上述したようにマウスピース３０の開口断面積Ａ１は収容室１３０の開口断面積Ａ２と比較して大きくなるように設計されている（図４参照）。したがって、使用者がマウスピース３０を咥えて吸引すると、ベンチュリー効果によってマウスピース３０内を通過する空気の流速よりも収容室１３０内を通過する空気の方が速くなり、吸引力をより高める効果を得られる。
なお、吸入補助器具の素材は特に限定されるものではなく、例えばプラスチック樹脂、シリコーン樹脂、金属、ゴム等が挙げられ、あるいはこれらを適宜組み合わせたものであってもよい。
また、吸入器の構造も特に限定されるものではなく、例えば図６に示すように１つの容器２００内に２つの収容室２０１、２０２を備えており、左右方向にスライドさせることで左右の収容室２０１、２０２に収容された各経口粉末Ｐを吸入する構造を備えたものであってもよい。
また、一方向弁４０をマウスピース３０の内側面に取り付けることにしてもよい。
また、装着部２０、マウスピース３０及び一方向弁４０の形状は楕円形に限定されるものではなく、正円形や多角形であってもよい。 Further, as described above, the opening cross-sectional area A1 of themouthpiece 30 is designed to be larger than the opening cross-sectional area A2 of the storage chamber 130 (see FIG. 4). Therefore, when the user holds the mouthpiece 30 and sucks it, the air passing through the accommodation chamber 130 is faster than the flow velocity of the air passing through the mouthpiece 30 due to the venturi effect, and the suction force is further increased. can get.
In addition, the material of the inhalation assisting device is not particularly limited, and examples thereof include plastic resin, silicone resin, metal, rubber, and the like, or a combination thereof as appropriate.
Also, the structure of the inhaler is not particularly limited. For example, as shown in FIG. 6, two container chambers 201 and 202 are provided in one container 200, and left and right containers can be accommodated by sliding left and right. It may have a structure for inhaling each oral powder P accommodated in the chambers 201 and 202.
Further, the one-way valve 40 may be attached to the inner surface of the mouthpiece 30.
Moreover, the shape of the mountingpart 20, the mouthpiece 30, and the one-way valve 40 is not limited to an ellipse, and may be a regular circle or a polygon.
