特開2003−175103号公報
As a powder medicine administration device, a powder medicine introduced from a medicine reservoir into a medicine receiving chamber is worn out to discharge a fixed amount of powder medicine together with air.
JP 2003-175103 A

しかしながら、上記特許文献1の粉末薬剤投与器では、擦り切り作用が不十分で、薬剤受室への粉末薬剤の充填が不十分となる場合があった。   However, in the powder medicine administration device of the above-mentioned patent document 1, there is a case where the scraping action is insufficient and the powder medicine is not sufficiently filled into the medicine receiving chamber.

そこで、本発明は、薬剤受室への粉末薬剤の充填率を高めることが可能な粉末薬剤投与器を得ようとするものである。   Therefore, the present invention seeks to obtain a powder medicine administration device capable of increasing the filling rate of the powder medicine into the medicine receiving chamber.

本発明にあっては、薬剤受室が待機位置から排出位置に移動するまでの間に、薬剤受室の開口部としての下側開口部の全域が薬剤貯留室からの粉末薬剤の出口となる上側開口部の内側に収まった状態のまま薬剤受室が移動する区間を設け、この薬剤受室が移動する区間は、前記薬剤受室が前回の前記排出位置から前記待機位置を経て次回の前記排出位置に移動するまでの間に、当該薬剤受室の開口部としての下側開口部の全域が前記上側開口部の内側に収まった状態のまま当該薬剤受室が往復移動する区間であり、前記上側本体部と下側本体部との相対スライドによって前記薬剤受室が前記上側開口部の下を通り抜けることにより前記非連通状態から前記連通状態を経て前記非連通状態とに切り替わる粉末薬剤の薬剤受室への導入および擦り切りのストロークを、前記相対スライド方向が異なるように複数回行った後に、前記薬剤受室が前記排出位置に到達するように構成したことを特徴とする。 In the present invention, the entire area of the lower opening serving as the opening of the medicine receiving chamber serves as an outlet for the powder medicine from the medicine storage chamber until the medicine receiving chamber moves from the standby position to the discharge position. The section in which the medicine receiving chamber moves while staying inside the upper opening is provided , and the section in which the medicine receiving chamber moves is the next time the medicine receiving chamber passes through the standby position from the previous discharge position. Before moving to the discharge position, the drug receiving chamber is a section in which the entire lower opening as the opening of the drug receiving chamber is reciprocated while being kept inside the upper opening, A powder medicine agent that switches from the non-communication state to the non-communication state through the communication state when the medicine receiving chamber passes under the upper opening by relative sliding between the upper body portion and the lower body portion. Introduction and rubbing into the reception room Ri of the stroke, after the relative sliding direction is performed a plurality of times to be different, and wherein the medicine receiving chamber is configured to reach the discharge position.

本発明によれば、下側開口部の全域が上側開口部と連通したまま薬剤受室が移動する間に摩擦によって薬剤受室内で粉末薬剤を流動させ、薬剤受室への粉末薬剤の充填率を高めることができる。
また、往復移動する区間の往路と復路とで薬剤受室内における粉末薬剤の流動方向を反転させることができ、相対移動する間で粉末薬剤を一方向のみに流動させる場合に比べて薬剤受室内で粉末薬剤の密度に偏りが生じるのを抑制して、充填性をより一層高めることが可能となる。
また、薬剤受室への粉末薬剤の導入ならびに擦り切りのストロークを複数回行うことで、薬剤受室に粉末薬剤を充填する機会が増える分、粒子間の隙間をより均一にすることができ、充填率を向上することができる。
ここで、薬剤受室における粉末薬剤の充填状態の密度が当該薬剤受室の移動方向に依存する場合がある。よって、本発明のように、相対スライド方向の異なる複数のストロークの後に薬剤受室を排出位置に到達させるようにすれば、薬剤受室における充填状態のばらつきを減らすことができる。
According to the present invention, the powder medicine flows in the medicine receiving chamber by friction while the medicine receiving chamber moves while the entire area of the lower opening is in communication with the upper opening, and the filling rate of the powder medicine into the medicine receiving chamber Can be increased.
Moreover, the flow direction of the powder medicine in the medicine receiving chamber can be reversed between the forward path and the return path of the reciprocating section, and the powder medicine flows in only one direction during the relative movement. It is possible to further increase the filling property by suppressing the occurrence of unevenness in the density of the powder medicine.
In addition, the introduction of the powder medicine into the medicine receiving chamber and the stroke of the scraping are performed several times, so that the opportunity for filling the medicine receiving chamber with the powder medicine can be increased, and the gaps between the particles can be made more uniform. The rate can be improved.
Here, the density of the charged state of the powder medicine in the medicine receiving chamber may depend on the moving direction of the medicine receiving chamber. Therefore, if the medicine receiving chamber is made to reach the discharge position after a plurality of strokes having different relative slide directions as in the present invention, it is possible to reduce variation in the filling state in the medicine receiving chamber.

図1〜図7に示すように、粉末薬剤投与器1は、相対スライド可能な二つの本体部として、上側本体部2と下側本体部3とを備えている。図3に示すように、これら上側本体部2および下側本体部3は、上下に重なり合う円盤部2b,3bを有しており、上側本体部2の円盤部2bの略円環状の下面2aと下側本体部3の円盤部3bの略円環状の上面3aとが相互に摺動するようになっている。そして、円盤部2bの中央部には、下面2aから垂直下方に伸びる略円柱状の軸部2iが形成される一方、円盤部3bの中央部には上面3aに対して垂直方向に伸びる貫通孔3eが形成されており、この軸部2iが貫通孔3eに回動可能に挿入されている。すなわち、本参考例では、軸部2iが貫通孔3eに回動可能に挿入されることで、これら軸部2iおよび貫通孔3eの中心軸(回動軸Ax)回りに上側本体部2と下側本体部3とが相対回動(相対スライド)し、これにより、下面2aと上面3aとが相互に周方向に摺動するようになっている。なお、上側本体部2は、下側本体部3の下方に位置する底壁部2jを有している。軸部2iは円盤部2bと底壁部2jとの間に架設され、下側本体部3の円盤部3bは上側本体部2の円盤部2bと底壁部2jとの間に挟装されている。 As shown in FIGS. 1 to 7, the powder medicine administration device 1 includes an upper main body 2 and a lower main body 3 as two main bodies that can be slid relative to each other. As shown in FIG. 3, the upper main body 2 and the lower main body 3 have disk portions 2 b and 3 b that are vertically overlapped, and a substantially annular lower surface 2 a of the disk portion 2 b of the upper main body 2. The substantially circular upper surface 3a of the disk part 3b of the lower main body part 3 slides relative to each other. A substantially cylindrical shaft portion 2i extending vertically downward from the lower surface 2a is formed at the central portion of the disk portion 2b, while a through hole extending perpendicularly to the upper surface 3a is formed at the central portion of the disk portion 3b. 3e is formed, and this shaft portion 2i is rotatably inserted into the through hole 3e. That is, in this reference example , the shaft portion 2i is rotatably inserted into the through hole 3e, so that the upper body portion 2 and the lower body 2 are rotated around the central axis (rotation axis Ax) of the shaft portion 2i and the through hole 3e. The side main body 3 is relatively rotated (relative sliding), whereby the lower surface 2a and the upper surface 3a slide in the circumferential direction. The upper body 2 has a bottom wall 2j located below the lower body 3. The shaft portion 2i is constructed between the disc portion 2b and the bottom wall portion 2j, and the disc portion 3b of the lower main body portion 3 is sandwiched between the disc portion 2b of the upper main body portion 2 and the bottom wall portion 2j. Yes.

また、図1〜図5に示すように、上側本体部2の円盤部2bの側面には、当該円盤部2bの径方向外側に向けて筒状部2cが突設されている。図1,図3等に示すように、筒状部2cの先端には空気通路6の出口としての排出口6fが形成されており、この排出口6fから空気と粉末薬剤(粉末薬剤と空気との攪拌流)とが排出されるようになっている。   Moreover, as shown in FIGS. 1-5, the cylindrical part 2c protrudes in the side surface of the disk part 2b of the upper side main-body part 2 toward the radial direction outer side of the said disk part 2b. As shown in FIGS. 1, 3 and the like, a discharge port 6f as an outlet of the air passage 6 is formed at the tip of the cylindrical portion 2c, and air and powder drug (powder drug and air) are formed from the discharge port 6f. The agitating flow) is discharged.

また、図1〜図5に示すように、本参考例では、下方に向けて開放された有底円筒状に形成されて上側本体部2を上方から覆うカバー4が設けられている。このカバー4の下縁と上側本体部2との上縁との間には、図2に示すように、スリット13を形成してある。下側本体部3の円盤部3bからその径外方向に突出するハンドル部3fは、このスリット13を介してカバー4および上側本体部2の側外方に突出している。このハンドル部3を操作することで、下側本体部3を上側本体部2に対して相対回動(相対スライド)させることができる。このとき、スリット13の形成範囲を適宜に設定することで、ハンドル部3の操作範囲、すなわち、下側本体部3が上側本体部2に対して相対回動(相対スライド)する範囲を設定することができる。また、本参考例では、このスリット13がカバー4内の空間Sと外部とを連通することで、空気通路6における空気の通流が可能となっている。 Moreover, as shown in FIGS. 1-5, in this reference example , the cover 4 which is formed in the bottomed cylindrical shape open | released downward and covers the upper side main-body part 2 from upper direction is provided. A slit 13 is formed between the lower edge of the cover 4 and the upper edge of the upper body 2 as shown in FIG. A handle portion 3 f that protrudes radially outward from the disk portion 3 b of the lower main body portion 3 protrudes outward from the cover 4 and the upper main body portion 2 through the slit 13. By operating the handle portion 3, the lower body portion 3 can be relatively rotated (relatively slid) with respect to the upper body portion 2. At this time, by appropriately setting the formation range of the slit 13, an operation range of the handle portion 3, that is, a range in which the lower main body portion 3 is relatively rotated (relatively slid) with respect to the upper main body portion 2 is set. be able to. In this reference example , the slit 13 communicates the space S in the cover 4 with the outside, so that air can flow in the air passage 6.

空気通路6は、図3に示すように、上側本体部2に形成されており、入口開口6aから上側本体部2を上下に貫通する通路6bと、通路6bの下端側に近い途中位置から側方に伸びて筒状部2c内の中央を貫通して排出口6fに至る通路6hと、を有している。   As shown in FIG. 3, the air passage 6 is formed in the upper main body portion 2, and includes a passage 6 b that vertically penetrates the upper main body portion 2 from the inlet opening 6 a and a midway position near the lower end side of the passage 6 b. And a passage 6h extending through the center of the cylindrical portion 2c to reach the discharge port 6f.

そして、図1,図3に示すように、使用状態では、通路6bの下端の開口部6gと粉末薬剤Mが充填された薬剤受室10とが重なり合い、薬剤受室10が空気通路6に臨むようになっている。すなわち、この状態で、薬剤受室10は排出位置Pdに位置している。この使用状態で、使用者が筒状部2cを口でくわえて吸い込むことにより、空気通路6に空気流が生じ、通路6b,6hで薬剤受室10内の粉末薬剤Mと空気とが攪拌され、空気と粉末薬剤Mとの混合流が排出口6fから使用者の口内に取り込まれる。   As shown in FIGS. 1 and 3, in use, the opening 6 g at the lower end of the passage 6 b and the medicine receiving chamber 10 filled with the powder medicine M overlap each other, and the medicine receiving chamber 10 faces the air passage 6. It is like that. That is, in this state, the medicine receiving chamber 10 is located at the discharge position Pd. In this state of use, when the user sucks the cylindrical portion 2c through the mouth, an air flow is generated in the air passage 6, and the powder medicine M and the air in the medicine receiving chamber 10 are stirred in the passages 6b and 6h. The mixed flow of air and powdered medicine M is taken into the user's mouth from the discharge port 6f.

図7に示すように、粉末薬剤Mを蓄える薬剤貯留室5は、回動軸Axと同心の略扇形断面(図1,図4,図6等参照)で上側本体部2の円盤部2bを上下に貫通する貫通穴と、当該貫通穴の下端を塞ぐ下側本体部3の上面3aと、当該貫通穴の上端を塞ぐキャップ15と、で囲まれた略密閉空間として形成されている。貫通穴の下端は、開口部(上側開口部)5aとなっており、この開口部5aを介して薬剤貯留室5内の粉末薬剤Mが下側本体部3の上面3aに形成された薬剤受室10に充填されるようになっている。薬剤受室10への粉末薬剤Mの充填については後述する。   As shown in FIG. 7, the drug storage chamber 5 for storing the powdered drug M has a substantially fan-shaped cross section (see FIGS. 1, 4, 6, etc.) concentric with the rotation axis Ax, and the disk part 2b of the upper body part 2 is formed. It is formed as a substantially sealed space surrounded by a through hole penetrating vertically, an upper surface 3a of the lower main body 3 that closes the lower end of the through hole, and a cap 15 that closes the upper end of the through hole. The lower end of the through-hole is an opening (upper opening) 5a, and the drug receiver M formed in the upper body 3a of the lower main body 3 is filled with the powder medicine M in the medicine storage chamber 5 through the opening 5a. The chamber 10 is filled. The filling of the powder medicine M into the medicine receiving chamber 10 will be described later.

そして、図8に示すように、この開口部5aの周方向(すなわち相対スライド方向)の両側の端縁は面取りされて、開放側(この場合は上面3a側)に向けて拡開する(すなわち開口面積を拡大する)傾斜面5bが形成されている。   And as shown in FIG. 8, the edge of the both sides of the circumferential direction (namely, relative sliding direction) of this opening part 5a is chamfered, and it expands toward the open side (in this case, the upper surface 3a side). An inclined surface 5b (which enlarges the opening area) is formed.

図9は、薬剤受室を示す図であって、(a)は平面図、(b)は一部の断面図である。この図9に示すように、薬剤受室10は、下側本体部3の上面3aを凹設して形成されており、本参考例では、複数のディンプル状の小孔10aを配列して形成されている。このとき、これら小孔10aの開口部(下側開口部)10bの面積は、いずれも薬剤貯留室5の開口部(上側開口部)5aの面積より小さくしてある。 FIG. 9 is a view showing the medicine receiving chamber, where (a) is a plan view and (b) is a partial sectional view. As shown in FIG. 9, the medicine receiving chamber 10 is formed by recessing the upper surface 3a of the lower main body 3. In this reference example , a plurality of dimple-shaped small holes 10a are arranged. Has been. At this time, the area of the opening (lower opening) 10b of these small holes 10a is smaller than the area of the opening (upper opening) 5a of the medicine reservoir 5.

図4,図5は、使用する前の状態を示しており、このとき薬剤受室10は、待機位置Paに位置している。この状態では、図7に示すように、薬剤貯留室5の開口部5aと薬剤受室10とが互いに重なり合い、重力により、薬剤貯留室5内の粉末薬剤Mが開口部5aを介して薬剤受室10内に充填される。すなわち、このとき、薬剤受室10は充填位置Pbにあり、薬剤貯留室5(の開口部5a)と薬剤受室10とは連通状態にある。図4,図7から、この状態では、薬剤受室10を成す個々の小孔10aはもとより、複数の小孔10aの全てが薬剤貯留室5の開口部5a内に同時に収まっていることがわかる。   4 and 5 show a state before use. At this time, the medicine receiving chamber 10 is located at the standby position Pa. In this state, as shown in FIG. 7, the opening 5a of the medicine storage chamber 5 and the medicine receiving chamber 10 overlap each other, and due to gravity, the powder medicine M in the medicine storage chamber 5 is received through the opening 5a. The chamber 10 is filled. That is, at this time, the medicine receiving chamber 10 is in the filling position Pb, and the medicine storage chamber 5 (the opening 5a thereof) and the medicine receiving chamber 10 are in communication. 4 and 7, it can be seen that in this state, not only the individual small holes 10a forming the drug receiving chamber 10 but also all of the plurality of small holes 10a are simultaneously accommodated in the opening 5a of the drug reservoir chamber 5. .

そして、図4,図5に示す状態から、使用者はハンドル部3fを動かして上側本体部2に対して下側本体部3を図4中の反時計回りに相対回動させ、図1,図3に示す状態にする。この状態では、粉末薬剤Mが充填された薬剤受室10が、開口部6gから空気通路6に臨むことになる。すなわち、このとき薬剤受室10は排出位置Pdにある。また、空気通路6は、入口開口6aおよび排出口6fの双方が外気と連通して、空気の通流が可能となっている。よって、使用者の吸引によって空気通路6に空気流が生じると、通路6bから流入した空気によって薬剤受室10に充填された粉末薬剤Mが効率良く巻き上げられるとともに空気と攪拌され、粉末薬剤Mが使用者の口腔内に効率良く入り込むことになる。   4 and 5, the user moves the handle 3f to rotate the lower body 3 relative to the upper body 2 counterclockwise in FIG. The state shown in FIG. In this state, the medicine receiving chamber 10 filled with the powder medicine M faces the air passage 6 from the opening 6g. That is, at this time, the medicine receiving chamber 10 is at the discharge position Pd. In addition, the air passage 6 allows air to flow through both the inlet opening 6a and the outlet 6f communicating with outside air. Therefore, when an air flow is generated in the air passage 6 by the user's suction, the powder medicine M filled in the medicine receiving chamber 10 is efficiently rolled up by the air flowing in from the passage 6b and stirred with the air. It will efficiently enter the user's mouth.

そして、使用後、使用者はハンドル部3fを動かして上側本体部2に対して下側本体部3を図1中の時計回り方向に相対回動させ、図4,図5に示す状態にする。   After use, the user moves the handle portion 3f to rotate the lower main body portion 3 relative to the upper main body portion 2 in the clockwise direction in FIG. 1, so that the state shown in FIGS. .

以上のように、図4,5の状態から、図1,3の状態を経て、図4,5の状態に遷移することで、薬剤貯留室5の開口部5aと薬剤受室10との相対的な位置関係が変化し、薬剤受室10が開口部5aの下を相対スライド方向(図1,図4の周方向)に往復したことがわかる。薬剤受室10が開口部5aと重なり合っている間は、開口部5aを介して粉末薬剤Mが薬剤受室10に充填され、開口部5aとの重なり合いが解消された後は、薬剤受室10の粉末薬剤Mが上側本体部2の下面2aで擦り切られることになる。すなわち、上記状態の遷移が、開口部5aと薬剤受室10との非連通状態から連通状態を経て非連通状態とに切り替わる粉末薬剤Mの薬剤受室10への導入および擦り切りの1ストロークとなっている。   As described above, the transition between the state of FIGS. 4 and 5 through the state of FIGS. 1 and 3 and the state of FIGS. It can be seen that the general positional relationship has changed, and the medicine receiving chamber 10 has reciprocated in the relative sliding direction (circumferential direction in FIGS. 1 and 4) under the opening 5a. While the medicine receiving chamber 10 overlaps the opening 5a, the powder medicine M is filled into the medicine receiving chamber 10 through the opening 5a, and after the overlap with the opening 5a is eliminated, the medicine receiving chamber 10 The powder medicine M is scraped off on the lower surface 2a of the upper main body 2. That is, the transition of the state is one stroke of introduction and fraying of the powder medicine M that switches from the non-communication state between the opening 5a and the medicine receiving chamber 10 to the non-communication state through the communication state. ing.

そして、本参考例では、薬剤受室10が待機位置Paから排出位置Pdに移動するまでの間に、全ての薬剤受室10の開口部10b(下側開口部)の全域が薬剤貯留室5の開口部5a(上側開口部)の内側に収まった状態のまま当該薬剤受室10が移動する区間を設けた。 In this reference example , the entire region of the opening 10b (lower opening) of all the drug receiving chambers 10 is the drug storage chamber 5 until the drug receiving chamber 10 moves from the standby position Pa to the discharge position Pd. A section in which the medicine receiving chamber 10 moves is provided in a state of being accommodated inside the opening 5a (upper opening).

すなわち、本参考例では、薬剤受室10が、前回の排出位置Pd(図1)から待機位置Pa(図4)を経て次回の排出位置Pd(図1)に移動するまでの間に、図4中に示す位置Pe(薬剤受室10の全ての小孔10aの開口部10bが薬剤貯留室5の開口部5aの内側に収まった位置であって排出位置Pdに最も近い側の位置)から折返位置Pc(薬剤受室10の全ての小孔10aの開口部10bが薬剤貯留室5の開口部5aの内側に収まった位置であって排出位置Pdから最も遠い側の位置)を経て位置Peへ往復移動し、その間、当該薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aの内側に収まった状態のまま移動するようにしてある。このため、図1に示すように、薬剤貯留室5の開口部5aの幅(相対回動の径方向の幅W1)を薬剤受室10の形成領域の幅W0より広くするとともに、図4に示すように、薬剤貯留室5の角度θ1を薬剤受室10の形成領域の角度θ0より大きくしてある。なお、位置Pc,Peは、いずれも充填位置Pbでもある。 In other words, in the present reference example , the drug receiving chamber 10 is moved from the previous discharge position Pd (FIG. 1) to the next discharge position Pd (FIG. 1) through the standby position Pa (FIG. 4). 4 (position where the openings 10b of all the small holes 10a of the medicine receiving chamber 10 are located inside the openings 5a of the medicine storage chamber 5 and closest to the discharge position Pd). Position Pe through the folding position Pc (the position where the openings 10b of all the small holes 10a of the medicine receiving chamber 10 are located inside the openings 5a of the medicine storage chamber 5 and farthest from the discharge position Pd). In the meantime, the entire region of the opening 10b of the medicine receiving chamber 10 is moved while being accommodated inside the opening 5a of the medicine storage chamber 5. For this reason, as shown in FIG. 1, the width of the opening 5a of the drug reservoir 5 (the width W1 in the radial direction of the relative rotation) is made wider than the width W0 of the formation region of the drug receiving chamber 10, and FIG. As shown, the angle θ1 of the medicine storage chamber 5 is larger than the angle θ0 of the formation region of the medicine receiving chamber 10. The positions Pc and Pe are both filling positions Pb.

さらに、本参考例では、図4に示すように、薬剤受室10の複数の小孔10aの開口部10bが開口部5aの中心C(平面視での中心)より回動軸Axの径方向外側を移動するように構成してある。 Furthermore, in this reference example , as shown in FIG. 4, the openings 10b of the plurality of small holes 10a of the medicine receiving chamber 10 are arranged in the radial direction of the rotation axis Ax from the center C (center in plan view) of the opening 5a. It is configured to move outside.

以上説明したように、本参考例では、薬剤受室10が待機位置Paから排出位置Pdに移動するまでの間に、当該薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aの内側に収まった状態のまま当該薬剤受室10が移動する区間を設けた。 As described above, in this reference example , the entire area of the opening 10b of the medicine receiving chamber 10 is the opening of the medicine storage chamber 5 until the medicine receiving chamber 10 moves from the standby position Pa to the discharge position Pd. A section in which the medicine receiving chamber 10 moves is provided in a state of being accommodated inside 5a.

発明者らの研究により、薬剤受室10内で粉末薬剤Mを流動させることによって、薬剤受室10内での粉末薬剤Mの密度をより均一化でき、粉末薬剤Mの充填率を高められることが判明した。よって、かかる構成によれば、薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aと連通したまま薬剤受室10が移動する間に、摩擦によって薬剤受室10内で粉末薬剤Mを流動させることができるので、薬剤受室10への粉末薬剤Mの充填率を高めることができる。   According to the inventors' research, the density of the powder medicine M in the medicine receiving chamber 10 can be made more uniform and the filling rate of the powder medicine M can be increased by flowing the powder medicine M in the medicine receiving chamber 10. There was found. Therefore, according to this configuration, while the medicine receiving chamber 10 moves while the entire area of the opening 10b of the medicine receiving chamber 10 is in communication with the opening 5a of the medicine storage chamber 5, powder is generated in the medicine receiving chamber 10 by friction. Since the medicine M can be flowed, the filling rate of the powder medicine M into the medicine receiving chamber 10 can be increased.

特に、本参考例では、上側本体部2と下側本体部3とを回動軸Ax回りに相対回動させるとともに、薬剤受室10の各小孔10aを半球状に形成したため、薬剤受室10の開口部10bが開口部5aと連通している状態で、粉末薬剤Mを薬剤受室10の各小孔10aの内壁に沿ってより円滑に流動させることができ、上記充填率を高める効果を増大することができる。なお、半球状に限らず、有底円筒状など、略曲面状に連続する内周壁を有する薬剤受室10であれば、同様の効果を得ることができる。 In particular, in this reference example , the upper body portion 2 and the lower body portion 3 are relatively rotated about the rotation axis Ax, and the small holes 10a of the drug receiving chamber 10 are formed in a hemispherical shape. The effect that the powder medicine M can flow more smoothly along the inner wall of each small hole 10a of the medicine receiving chamber 10 in a state where the ten openings 10b communicate with the opening 5a, and the filling rate is increased. Can be increased. In addition, the same effect can be acquired if it is the chemical | medical agent receiving chamber 10 which has not only a hemisphere but the inner peripheral wall which continues substantially curved shape, such as a bottomed cylindrical shape.

また、本参考例では、薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aの内側に収まった状態のまま当該薬剤受室10が往復移動する区間(Pe→Pc→Pe)を設けた。 Further, in this reference example , a section (Pe → Pc → Pe) in which the medicine receiving chamber 10 reciprocates while the entire area of the opening 10b of the medicine receiving chamber 10 is kept inside the opening 5a of the medicine storage chamber 5. ).

よって、往復移動する区間の往路と復路とで薬剤受室10内における粉末薬剤Mの流動方向を反転させることができ、相対移動する間で粉末薬剤Mを一方向のみに流動させる場合に比べて薬剤受室10内で粉末薬剤Mの密度に偏りが生じるのを抑制して、充填性をより一層高めることが可能となる。   Therefore, the flow direction of the powder medicine M in the medicine receiving chamber 10 can be reversed between the forward path and the return path of the reciprocating section, and compared with the case where the powder medicine M flows in only one direction during the relative movement. It is possible to further increase the filling property by suppressing the occurrence of unevenness in the density of the powder medicine M in the medicine receiving chamber 10.

また、本参考例では、上側本体部2と下側本体部3とが略上下に伸びる回動軸Axを中心として相対回動可能に構成され、開口部10bが薬剤貯留室5の開口部5aの中心Cに対して回動軸Axの径方向外側を移動する薬剤受室10を含むように構成した。 Further, in the present reference example , the upper main body 2 and the lower main body 3 are configured to be relatively rotatable about a rotation axis Ax extending substantially vertically, and the opening 10b is the opening 5a of the medicine storage chamber 5. The medicine receiving chamber 10 is configured to move on the outer side in the radial direction of the rotation axis Ax with respect to the center C.

薬剤受室10が中心Cに対して回動軸Axの径方向外側を移動するほど、薬剤受室10における粉末薬剤Mの相対的な流動速度が高まるため、かかる構成とすることで、薬剤受室10内で粉末薬剤Mをより大きく流動させ、薬剤受室10内で粉末薬剤Mの密度に偏りが生じるのを抑制して、充填性をより一層高めることが可能となる。   Since the relative flow speed of the powdered medicine M in the medicine receiving chamber 10 increases as the medicine receiving chamber 10 moves radially outward of the rotation axis Ax with respect to the center C, this configuration allows the medicine receiving It is possible to further increase the filling property by causing the powder medicine M to flow more greatly in the chamber 10 and suppressing the density of the powder medicine M in the medicine receiving chamber 10 from being biased.

また、本参考例では、開口部5aの相対スライド方向側の縁に、開放側に向けて拡開する傾斜面5bを形成した。 Moreover, in this reference example , the inclined surface 5b which expands toward the open side was formed at the edge on the relative sliding direction side of the opening 5a.

この傾斜面5bによって、薬剤受室10が開口部5aの下を相対スライドする際に、当該粉末薬剤Mを薬剤受室10へ充填する作用が働くようになるため、薬剤受室10への粉末薬剤Mの充填効率を高めることができる。   The inclined surface 5b acts to fill the medicine receiving chamber 10 with the powder medicine M when the medicine receiving chamber 10 slides relative to the bottom of the opening 5a. The filling efficiency of the medicine M can be increased.

また、本参考例では、開口部5aに同時に連通しかつ排出位置Pdで同時に空気通路6に臨む複数の薬剤受室10としての小孔10aを設けた。 Further, in this reference example , a plurality of small holes 10a serving as a plurality of medicine receiving chambers 10 that are simultaneously communicated with the opening 5a and simultaneously face the air passage 6 at the discharge position Pd are provided.

薬剤受室10を一箇所に大きく設けた場合には、当該薬剤受室10内の他の領域に存在する粉末薬剤Mの動きの影響を受けて粉末薬剤Mの充填率のばらつきが生じやすくなる。この点、本参考例では、複数の小孔10aを一つの薬剤受室10として、細分化して(分散して)設けることで、他の領域からの影響を抑制して充填率を向上することができる。 When the medicine receiving chamber 10 is provided large in one place, the filling rate of the powder medicine M is likely to vary due to the influence of the movement of the powder medicine M existing in other regions in the medicine receiving chamber 10. . In this respect, in this reference example , by providing a plurality of small holes 10a as one medicine receiving chamber 10 in a subdivided (distributed) manner, the influence from other regions is suppressed and the filling rate is improved. Can do.

また、本参考例では、開口部5aに同時に連通する複数の小孔10aの開口部10bの全てが開口部5a内に収まる状態が得られるようにした。 Further, in this reference example , a state is obtained in which all of the openings 10b of the plurality of small holes 10a communicating with the opening 5a at the same time are accommodated in the openings 5a.

複数の小孔10aが別々のタイミングで開口部5aに連通すると、粉末薬剤Mを各小孔10aに充填する際の自重による圧力にばらつきが生じ、充填率がばらつく虞がある。この点、本参考例では、複数の小孔10aの全てが開口部5aに連通する状態が得られるようにしたため、各小孔10aに対する粉末薬剤Mの充填圧力を均一化できて、充填ばらつきを低減して、充填率を向上することができる。 When the plurality of small holes 10a communicate with the opening 5a at different timings, there is a possibility that the pressure due to the weight of the powder medicine M when filling the small holes 10a varies and the filling rate varies. In this respect, in this reference example , since the state in which all of the plurality of small holes 10a communicate with the opening 5a is obtained, the filling pressure of the powder medicine M to each small hole 10a can be made uniform, and filling variation is caused. It can reduce and a filling rate can be improved.

The agitating flow) is discharged.

また、図10〜図14に示すように、本実施形態では、排出口6fを覆うカバーとして、スライドカバー4Aが設けられている。このスライドカバー4Aは、円盤部2b,3bを外側から上下に挟み込む略矩形板状のプレート部4a,4bと、円盤部2bの貫通孔2eならびに筒状の軸部3cの筒内部としての貫通孔3dに嵌挿されてプレート部4a,4b間に架設される略円柱状の軸部4cと、プレート部4a,4bの長手方向一方側の端縁間で架設されて図10〜図12に示す非使用状態で筒状部2cの先端を覆う円弧状に屈曲した板状のカバー部4dと、を有している。そして、軸部4cが軸受として機能する貫通孔3d(2e)に回動可能に軸支されることで、これら軸部4cおよび貫通孔3d(2e)の中心軸回りにスライドカバー4Aと上側本体部2Aおよび下側本体部3Aとが相対回動するようになっている。   Moreover, as shown in FIGS. 10-14, in this embodiment, the slide cover 4A is provided as a cover which covers the discharge port 6f. The slide cover 4A includes substantially rectangular plate-like plate portions 4a and 4b that sandwich the disc portions 2b and 3b from the outside, a through-hole 2e of the disc portion 2b, and a through-hole as a cylinder inside of the cylindrical shaft portion 3c. 10 to 12, which are installed between the substantially cylindrical shaft portion 4 c that is inserted and inserted between the plate portions 4 a and 4 b and the edge on one side in the longitudinal direction of the plate portions 4 a and 4 b. A plate-like cover portion 4d bent in an arc shape covering the tip of the cylindrical portion 2c in a non-use state. The shaft portion 4c is pivotally supported by the through-hole 3d (2e) functioning as a bearing so that the slide cover 4A and the upper body are rotated around the central axes of the shaft portion 4c and the through-hole 3d (2e). The portion 2A and the lower main body portion 3A are relatively rotated.

また、図12に示すように、スライドカバー4Aの上側のプレート部4aには貫通孔4eが形成されている。図10〜図12に示す非使用状態では、空気通路6Aの入口開口6aはスライドカバー4Aの上側のプレート部4aによって覆われるとともに、空気通路6Aの排出口6fはスライドカバー4Aのカバー部4dによって覆われるようになっている。一方、図13,図14に示す使用状態では、上側本体部2Aとスライドカバー4Aとの相対回動(スライド)により、カバー部4dが空気通路6Aの排出口6fを開くとともに、貫通孔4eが空気通路6Aの入口開口6aと重なり合って、空気通路6Aの入口側および出口側の双方が外気と連通した状態が得られ、以て、空気通路6Aにおける空気流の通流が可能となる。   Further, as shown in FIG. 12, a through hole 4e is formed in the upper plate portion 4a of the slide cover 4A. 10 to 12, the inlet opening 6a of the air passage 6A is covered by the upper plate portion 4a of the slide cover 4A, and the discharge port 6f of the air passage 6A is covered by the cover portion 4d of the slide cover 4A. It is supposed to be covered. On the other hand, in the use state shown in FIGS. 13 and 14, the cover part 4d opens the outlet 6f of the air passage 6A and the through-hole 4e is formed by relative rotation (sliding) between the upper body part 2A and the slide cover 4A. Overlap with the inlet opening 6a of the air passage 6A, a state where both the inlet side and the outlet side of the air passage 6A communicate with the outside air is obtained, so that the air flow in the air passage 6A becomes possible.

空気通路6Aは、図12,図14に示すように、上側本体部2Aに形成されており、入口開口6aから上側本体部2Aを上下に貫通する通路6bと、下面2aに開口する開口部6gが下側本体部3Aの上面3aで塞がれて形成され下端の折り返し点となる通路6cと、通路6cから上方に伸びる通路6dと、通路6dの上端部から側方に伸びて筒状部2c内の中央を貫通して排出口6fに至る通路6eと、を有している。   As shown in FIGS. 12 and 14, the air passage 6A is formed in the upper main body 2A, and includes a passage 6b that vertically penetrates the upper main body 2A from the inlet opening 6a and an opening 6g that opens to the lower surface 2a. Is closed by the upper surface 3a of the lower body portion 3A and is formed as a turn-back point at the lower end, a passage 6d extending upward from the passage 6c, and a tubular portion extending laterally from the upper end of the passage 6d. And a passage 6e that passes through the center in 2c and reaches the discharge port 6f.

図13,図14に示すように、使用状態では、開口部6gと粉末薬剤Mが充填された薬剤受室10とが重なり合い、薬剤受室10が空気通路6Aに臨むようになっている。すなわち、この状態で、薬剤受室10は排出位置Pdに位置している。そして、この使用状態で、使用者が筒状部2cを口でくわえて吸い込むことにより、空気通路6Aに空気流が生じ、通路6cで薬剤受室10内の粉末薬剤Mと空気とが攪拌され、空気と粉末薬剤Mとの混合流が排出口6fから使用者の口内に取り込まれる。   As shown in FIGS. 13 and 14, in use, the opening 6g and the medicine receiving chamber 10 filled with the powder medicine M overlap each other, and the medicine receiving chamber 10 faces the air passage 6A. That is, in this state, the medicine receiving chamber 10 is located at the discharge position Pd. In this state of use, when the user sucks the cylindrical portion 2c through the mouth, an air flow is generated in the air passage 6A, and the powder medicine M and the air in the medicine receiving chamber 10 are stirred in the passage 6c. The mixed flow of air and powdered medicine M is taken into the user's mouth from the discharge port 6f.

また、図10,12〜14に示すように、本実施形態では、相対スライドする上側本体部2Aおよび下側本体部3Aについて、当該相対スライドを案内するとともにその可動範囲を規定する案内構造7が設けられている。具体的には、下側本体部3Aの上面3aに、相対回動の周方向に沿う円弧状の溝7aが形成されるとともに、上側本体部2Aの下面2aには、この溝7a内に挿入されて相対回動に伴って溝7a内を移動する突起7bが設けられている。また、突起7bと溝7aの長手方向端縁部7c,7dとの係止により、上側本体部2Aと下側本体部3Aとの相対回動範囲が規制されるようになっている。すなわち、この案内構造7は、上側本体部2Aと下側本体部3Aとを係止する係止構造としての機能を有している。   In addition, as shown in FIGS. 10 and 12 to 14, in the present embodiment, a guide structure 7 that guides the relative slide and defines the movable range of the upper main body 2 </ b> A and the lower main body 3 </ b> A that slide relative to each other. Is provided. Specifically, an arcuate groove 7a is formed on the upper surface 3a of the lower main body 3A along the circumferential direction of relative rotation, and the lower surface 2a of the upper main body 2A is inserted into the groove 7a. Thus, a projection 7b is provided that moves in the groove 7a with relative rotation. Further, the relative rotation range between the upper main body 2A and the lower main body 3A is regulated by the engagement between the protrusion 7b and the longitudinal edge portions 7c and 7d of the groove 7a. That is, the guide structure 7 has a function as a locking structure that locks the upper main body 2A and the lower main body 3A.

さらに、本実施形態では、相対スライドする上側本体部2Aおよびスライドカバー4Aについて、当該相対スライドを案内するとともにその可動範囲を規定する案内構造11が設けられている。具体的には、上側本体部2Aの上面に、相対回動の周方向に沿う円弧状の溝11aが形成されるとともに、スライドカバー4Aの上側のプレート部4aの下面には、この溝11a内に挿入されて相対回動に伴って溝11a内を移動する突起11bが設けられている。また、突起11bと溝11aの長手方向端縁部11c,11dとの係止により、上側本体部2Aとスライドカバー4Aとの相対回動範囲が規制されるようになっている。   Further, in the present embodiment, a guide structure 11 is provided for guiding the relative slide and defining the movable range of the upper main body 2A and the slide cover 4A that slide relative to each other. Specifically, an arc-shaped groove 11a is formed on the upper surface of the upper body portion 2A along the circumferential direction of relative rotation, and the lower surface of the upper plate portion 4a of the slide cover 4A is formed in the groove 11a. A protrusion 11b that is inserted into the groove 11a and moves in the groove 11a with relative rotation is provided. Further, the relative rotation range between the upper main body 2A and the slide cover 4A is restricted by the engagement between the protrusion 11b and the longitudinal edge portions 11c and 11d of the groove 11a.

図15,16は、上側本体部を示しており、このうち、図15は、上側本体部の下面図、図16は、図15のXVI−XVI断面図である。粉末薬剤Mを蓄える薬剤貯留室5Aは、軸受部2dおよび貫通孔2eと同心の略扇形断面で上側本体部2Aの円盤部2bを上下に貫通する貫通穴と、当該貫通穴の下端を塞ぐ下側本体部3Aの上面3aと、当該貫通穴の上端を塞ぐキャップと、で囲まれた略密閉空間として形成されている。貫通穴の下端は、開口部(上側開口部)5aとなっており、この開口部5aを介して薬剤貯留室5A内の粉末薬剤Mが下側本体部3Aの上面3aに形成された薬剤受室10に充填されるようになっている。薬剤受室10への粉末薬剤Mの充填については後述する。   15 and 16 show the upper main body, among which FIG. 15 is a bottom view of the upper main body, and FIG. 16 is a cross-sectional view taken along XVI-XVI in FIG. The medicine storage chamber 5A for storing the powdered medicine M has a substantially fan-shaped cross section concentric with the bearing portion 2d and the through hole 2e and vertically passes through the disk portion 2b of the upper body portion 2A, and a lower portion closing the lower end of the through hole. It is formed as a substantially sealed space surrounded by the upper surface 3a of the side main body 3A and a cap that closes the upper end of the through hole. The lower end of the through-hole is an opening (upper opening) 5a, and the drug receiving agent formed in the upper surface 3a of the lower body 3A is formed through the opening 5a. The chamber 10 is filled. The filling of the powder medicine M into the medicine receiving chamber 10 will be described later.

そして、本実施形態でも、上記参考例と同様に、開口部5aの周方向(すなわち相対スライド方向)の両側の端縁は面取りされて、開放側(この場合は上面3a側)に向けて拡開する(すなわち開口面積を拡大する)傾斜面5bが形成されている。また、薬剤受室10も、上記参考例と同じ構成としてある。 Also in this embodiment, as in the above reference example , the edges on both sides in the circumferential direction (that is, the relative sliding direction) of the opening 5a are chamfered and expanded toward the open side (in this case, the upper surface 3a side). An inclined surface 5b that opens (that is, increases the opening area) is formed. Moreover, the medicine receiving chamber 10 has the same configuration as that of the reference example .

また、図15,16に示すように、上側本体部2Aの円盤部2bには、薬剤貯留室5Aと同様の略扇形断面で下方に向けて開放される有底筒状の凹部として、薬剤回収室9が、周方向に沿って略等ピッチで複数形成されている。これら複数の薬剤回収室9はいずれも同じ形状で、所定厚さの隔壁2fによって仕切られている。隔壁2fの底面は、上側本体部2Aの下面2aと面一となっており、下側本体部3Aの上面3aと摺接する。この薬剤回収室9は、下面2aと上面3aとの間に付着した粉末薬剤Mを回収する。   As shown in FIGS. 15 and 16, the disc portion 2 b of the upper body portion 2 </ b> A has a substantially fan-shaped cross section similar to the drug reservoir chamber 5 </ b> A and has a bottomed cylindrical recess that opens downward. A plurality of chambers 9 are formed at substantially equal pitches along the circumferential direction. The plurality of drug recovery chambers 9 have the same shape and are partitioned by a partition wall 2f having a predetermined thickness. The bottom surface of the partition wall 2f is flush with the lower surface 2a of the upper body portion 2A and is in sliding contact with the upper surface 3a of the lower body portion 3A. The drug recovery chamber 9 recovers the powder drug M adhered between the lower surface 2a and the upper surface 3a.

なお、図15を見れば、上側本体部2Aが、薬剤貯留室5Aと薬剤回収室9とで当該図15の上下に略対称形状となっていることがわかる。かかる構成により、上側本体部2Aの重量バランスが向上するとともに、スライドカバー4Aのプレート部4a,4bによる挟持力に対する撓み剛性が均一化されて、上側本体部2Aの下面2aと下側本体部3Aの上面3aとの摺接部の隙間にばらつきが生じるなどしてシール性が低下するのを抑制することができる。また、粉末薬剤投与器1Aの軽量化に資するのも勿論である。   15, it can be seen that the upper main body 2A has a substantially symmetrical shape in the upper and lower parts of FIG. 15 in the medicine storage chamber 5A and the medicine collection chamber 9. With this configuration, the weight balance of the upper main body 2A is improved and the flexural rigidity with respect to the clamping force by the plates 4a and 4b of the slide cover 4A is made uniform, so that the lower surface 2a of the upper main body 2A and the lower main body 3A. It is possible to suppress deterioration of the sealing performance due to variations in the gap between the sliding contact portions with the upper surface 3a. Of course, it contributes to weight reduction of the powder medicine administration device 1A.

図17は、上側本体部とスライドカバーとの係合構造を示す水平断面図である。この図17に示すように、本実施形態では、上側本体部2Aの筒状部2cの先端部と、スライドカバー4Aのカバー部4dの当該筒状部2cとの対向部とを相互に係合する係合構造として、筒状部2cに設けた凹部8bと、この凹部8bに挿入されて係合する突起8aとを設けてある。かかる係合構造8の係合により、上側本体部2Aと下側本体部3Aとの相対スライドの際に、上側本体部2Aとスライドカバー4Aとを連動することができる。すなわち、スライドカバー4Aを下側本体部3Aに対して相対回動させることで、このスライドカバー4Aに連動して上側本体部2Aを相対回動させることができる。なお、この係合構造8による係合状態は、スライドカバー4Aと下側本体部3Aとの間に周方向に所定の大きさ以上の力を加えることで解除できるようになっている。   FIG. 17 is a horizontal sectional view showing an engagement structure between the upper main body and the slide cover. As shown in FIG. 17, in this embodiment, the tip of the cylindrical portion 2c of the upper body portion 2A and the facing portion of the cover portion 4d of the slide cover 4A facing the cylindrical portion 2c are engaged with each other. As an engaging structure, a concave portion 8b provided in the cylindrical portion 2c and a protrusion 8a inserted into and engaged with the concave portion 8b are provided. By the engagement of the engagement structure 8, the upper main body 2A and the slide cover 4A can be interlocked when the upper main body 2A and the lower main body 3A are relatively slid. That is, by rotating the slide cover 4A relative to the lower main body 3A, the upper main body 2A can be rotated relative to the slide cover 4A. The engagement state by the engagement structure 8 can be released by applying a force of a predetermined magnitude or more in the circumferential direction between the slide cover 4A and the lower main body 3A.

図18〜図20は、上側本体部と下側本体部とを相対スライドさせた場合の各段階における平面図、図21は、図18のXXI−XXI断面図である。   18 to 20 are plan views at each stage when the upper main body and the lower main body are slid relative to each other, and FIG. 21 is a cross-sectional view taken along XXI-XXI in FIG.

図10,図12は、非使用状態(静置状態)を示している。このとき、薬剤受室10は待機位置Paに位置している。待機位置Paでは、薬剤受室10は、開口部6gから略密閉された空気通路6Aに臨んおり、薬剤貯留室5A(の開口部5a)と薬剤受室10とは非連通状態にある。 10 and 12 show a non-use state (stationary state). At this time, the medicine receiving chamber 10 is located at the standby position Pa. In the standby position Pa, the medicine receiving chamber 10 faces the air passage 6A that is substantially sealed from the opening 6g , and the medicine storage chamber 5A (the opening 5a thereof ) and the medicine receiving chamber 10 are not in communication.

図10,図12の状態から、下側本体部3Aに対してスライドカバー4Aを図10中の反時計回り方向に相対回動させると、係合構造8によってスライドカバー4Aに係合される上側本体部2Aも当該スライドカバー4Aと一体となって回動し、図18,図21に示す状態となる。   10 and 12, when the slide cover 4A is relatively rotated counterclockwise in FIG. 10 with respect to the lower main body 3A, the upper side engaged with the slide cover 4A by the engagement structure 8 The main body 2A also rotates together with the slide cover 4A, and is in the state shown in FIGS.

図18,図21に示す状態では、薬剤貯留室5Aの開口部5aと薬剤受室10とが互いに重なり合い、図21に示すように、薬剤貯留室5A内の粉末薬剤Mが開口部5aを介して薬剤受室10内に充填される。すなわち、この状態で、薬剤受室10は充填位置Pbにあり、薬剤貯留室5A(の開口部5a)と薬剤受室10とは連通状態にある。図18から、この状態では、薬剤受室10を成す個々の小孔10aはもとより、複数の小孔10aの全てが薬剤貯留室5Aの開口部5a内に同時に収まっていることがわかる。   In the state shown in FIGS. 18 and 21, the opening 5a of the medicine reservoir 5A and the medicine receiving chamber 10 overlap each other, and as shown in FIG. 21, the powder medicine M in the medicine reservoir 5A passes through the opening 5a. The medicine receiving chamber 10 is filled. That is, in this state, the medicine receiving chamber 10 is at the filling position Pb, and the medicine storage chamber 5A (the opening 5a thereof) and the medicine receiving chamber 10 are in communication. FIG. 18 shows that in this state, not only the individual small holes 10a forming the drug receiving chamber 10, but also all of the plurality of small holes 10a are simultaneously accommodated in the opening 5a of the drug reservoir chamber 5A.

さらに、下側本体部3Aに対してスライドカバー4Aを図18中の反時計回りに相対回動させると、図19に示す状態となる。このとき、上側本体部2Aと下側本体部3Aとの案内構造7において、突起7bが溝7aの長手方向端縁部7cに係止されるため、上側本体部2Aは下側本体部3Aに対して図19の状態を越えて反時計回りに回動することはできない。一方、上側本体部2Aとスライドカバー4Aとの案内構造11では、突起11bは溝11aの途中にあり長手方向端縁部11cには到達していないため、スライドカバー4Aは図19の状態を越えて反時計回りに回動することができる。したがって、図19の状態で下側本体部3Aに対してスライドカバー4Aを所定の大きさ以上の力を加えながら反時計回り方向に回動させると、係合構造8による上側本体部2Aとスライドカバー4Aとの係合が解除され、それ以降はスライドカバー4Aのみが反時計回り方向に回動して、図20の状態となる。図19から図20へのスライドカバー4Aの回動により、当該スライドカバー4Aのカバー部4d(図12参照)が上側本体部2Aの筒状部2cの先端部を開放し、排出口6fが開放されることになる。   Further, when the slide cover 4A is relatively rotated counterclockwise in FIG. 18 with respect to the lower main body 3A, the state shown in FIG. 19 is obtained. At this time, in the guide structure 7 of the upper body portion 2A and the lower body portion 3A, the protrusion 7b is locked to the longitudinal edge portion 7c of the groove 7a, so the upper body portion 2A is connected to the lower body portion 3A. On the other hand, it cannot be rotated counterclockwise beyond the state shown in FIG. On the other hand, in the guide structure 11 of the upper body portion 2A and the slide cover 4A, the protrusion 11b is in the middle of the groove 11a and does not reach the longitudinal end edge portion 11c, so the slide cover 4A exceeds the state of FIG. Can be rotated counterclockwise. Therefore, when the slide cover 4A is rotated counterclockwise while applying a force of a predetermined magnitude or more to the lower main body 3A in the state of FIG. The engagement with the cover 4A is released, and thereafter, only the slide cover 4A rotates counterclockwise, and the state shown in FIG. 20 is obtained. By the rotation of the slide cover 4A from FIG. 19 to FIG. 20, the cover portion 4d (see FIG. 12) of the slide cover 4A opens the distal end portion of the cylindrical portion 2c of the upper body portion 2A, and the discharge port 6f opens. Will be.

そして、図10の状態から、図18の状態を経て、図19の状態に遷移することで、薬剤貯留室5Aの開口部5aと薬剤受室10との相対的な位置関係が変化し、開口部5aが薬剤受室10の上を相対スライド方向(すなわち周方向、図10,図13,図18〜図20の反時計回り方向)に通過した、換言すれば、薬剤受室10が開口部5aの下を相対スライド方向(すなわち周方向、図10,図13,図18〜図20の時計回り方向)に通過したことがわかる。薬剤受室10が開口部5aと重なり合っている間は、開口部5aを介して粉末薬剤Mが薬剤受室10に充填され、開口部5aとの重なり合いが解消された後は、薬剤受室10の粉末薬剤Mが上側本体部2Aの下面2aで擦り切られることになる。すなわち、図10の状態から図18の状態を経た図19の状態への遷移が、開口部5aと薬剤受室10との非連通状態から連通状態を経て非連通状態とに切り替わる粉末薬剤Mの薬剤受室10への導入および擦り切りの1ストロークとなっている。なお、図19の状態から図20の状態への遷移(スライドカバー4Aが上側本体部2Aから分離して単独で回動する事象)は、薬剤受室10が開口部5aの下を完全に通過した後に行われる。   Then, by changing from the state of FIG. 10 to the state of FIG. 19 through the state of FIG. 18, the relative positional relationship between the opening 5 a of the medicine storage chamber 5 </ b> A and the medicine receiving chamber 10 is changed. The portion 5a has passed over the medicine receiving chamber 10 in the relative sliding direction (that is, in the circumferential direction, the counterclockwise direction in FIGS. 10, 13, and 18 to 20), in other words, the medicine receiving chamber 10 is an opening. It can be seen that it passed under 5a in the relative sliding direction (that is, the circumferential direction, the clockwise direction in FIGS. 10, 13, and 18 to 20). While the medicine receiving chamber 10 overlaps the opening 5a, the powder medicine M is filled into the medicine receiving chamber 10 through the opening 5a, and after the overlap with the opening 5a is eliminated, the medicine receiving chamber 10 The powdered medicine M is scraped off at the lower surface 2a of the upper body portion 2A. That is, the transition from the state of FIG. 10 to the state of FIG. 19 through the state of FIG. 18 changes from the non-communication state between the opening 5a and the medicine receiving chamber 10 to the non-communication state through the communication state. It is one stroke of introduction into the medicine receiving chamber 10 and abrasion. Note that in the transition from the state of FIG. 19 to the state of FIG. 20 (an event in which the slide cover 4A is separated from the upper body portion 2A and independently rotates), the medicine receiving chamber 10 completely passes under the opening 5a. Done after.

さらに、図20でスライドカバー4Aから分離された上側本体部2Aのみを、図10,図18,図19の遷移とは逆の方向に相対スライドさせ、図13の状態にする。このとき、図20の状態から図13の状態への遷移においても、薬剤貯留室5Aの開口部5aと薬剤受室10との相対的な位置関係が変化し、開口部5aが薬剤受室10の上を相対スライド方向(すなわち周方向、図10,図13,図18〜図20の時計回り方向)に通過した、換言すれば、薬剤受室10が開口部5aの下を相対スライド方向(すなわち周方向、図10,図13,図18〜図20の反時計回り方向)に通過したことがわかる。つまり、図20の状態から図13の状態への遷移が、開口部5aと薬剤受室10との非連通状態から連通状態を経て非連通状態とに切り替わる粉末薬剤Mの薬剤受室10への導入および擦り切りの更なる1ストロークとなっている。なお、図19ならびに図20の状態では、薬剤受室10が折返位置Pcにあり、薬剤貯留室5A(の開口部5a)と薬剤受室10とが非連通状態にあることが理解できよう。   Further, only the upper main body 2A separated from the slide cover 4A in FIG. 20 is relatively slid in the direction opposite to the transition of FIGS. 10, 18, and 19 to obtain the state of FIG. At this time, also in the transition from the state of FIG. 20 to the state of FIG. 13, the relative positional relationship between the opening 5a of the medicine storage chamber 5A and the medicine receiving chamber 10 changes, and the opening 5a becomes the medicine receiving chamber 10. Passed in the relative sliding direction (that is, the circumferential direction, the clockwise direction in FIGS. 10, 13, and 18 to 20), in other words, the medicine receiving chamber 10 moves under the opening 5a in the relative sliding direction ( That is, it can be seen that it passed in the circumferential direction (counterclockwise direction in FIGS. 10, 13, and 18 to 20). That is, the transition from the state of FIG. 20 to the state of FIG. 13 changes from the non-communication state of the opening 5a and the medicine receiving chamber 10 to the non-communication state via the communication state to the medicine receiving chamber 10. One more stroke for introduction and fraying. 19 and 20, it can be understood that the medicine receiving chamber 10 is in the folding position Pc, and the medicine reservoir 5A (the opening 5a thereof) and the medicine receiving chamber 10 are in a non-communication state.

このように、本実施形態では、薬剤受室10が開口部5aの下を相対スライド方向に複数回(具体的には逆方向に2回)通過し、すなわち開口部5aを跨いで相対スライド方向に1往復した後に、排出位置Pdに到達し、かくして、図13,図14に示す使用状態(使用可能状態)となる。この状態では、上述したように、粉末薬剤Mが充填された薬剤受室10が、空気通路6Aに臨み、当該空気通路6Aは、入口開口6aおよび排出口6fの双方が外気と連通して、空気の通流が可能となっている。使用者の吸引によって空気通路6Aに空気流が生じると、薬剤受室10が臨む通路6cは折り返し点となっているため、通路6bから流入した空気が通路6cおよび通路6dに流れる際に剥離や乱流が生じる。このため、薬剤受室10に充填された粉末薬剤Mが効率良く巻き上げられるとともに攪拌され、粉末薬剤Mが粉末薬剤投与器1A内に残存するのを抑制することができ、粉末薬剤Mの投与効率を向上することができる。   Thus, in this embodiment, the medicine receiving chamber 10 passes under the opening 5a a plurality of times in the relative slide direction (specifically, twice in the reverse direction), that is, in the relative slide direction across the opening 5a. After one reciprocation, the discharge position Pd is reached, and the use state (usable state) shown in FIGS. In this state, as described above, the medicine receiving chamber 10 filled with the powder medicine M faces the air passage 6A, and both the inlet opening 6a and the outlet 6f communicate with the outside air in the air passage 6A. Air flow is possible. When an air flow is generated in the air passage 6A by the user's suction, the passage 6c facing the medicine receiving chamber 10 serves as a turning point. Therefore, when the air flowing from the passage 6b flows into the passage 6c and the passage 6d, separation or Turbulence occurs. For this reason, the powder medicine M filled in the medicine receiving chamber 10 can be efficiently rolled up and stirred, and the powder medicine M can be prevented from remaining in the powder medicine administration device 1A. Can be improved.

以上の本実施形態でも、上記参考例と同様に、薬剤受室10が待機位置Paから排出位置Pdに移動するまでの間に、当該薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aの内側に収まった状態のまま当該薬剤受室10が移動する区間を設けてある。 Also in the present embodiment described above, the entire area of the opening 10b of the drug receiving chamber 10 is the drug storage chamber 5 until the drug receiving chamber 10 moves from the standby position Pa to the discharge position Pd, as in the above reference example. A section in which the medicine receiving chamber 10 moves is provided in a state of being housed inside the opening 5a.

よって、かかる構成でも、薬剤受室10の開口部10bの全域が薬剤貯留室5の開口部5aと連通したまま薬剤受室10が移動する間に、摩擦によって薬剤受室10内で粉末薬剤Mを流動させることができるので、薬剤受室10への粉末薬剤Mの充填率を高めることができる。   Therefore, even in such a configuration, the powder medicine M is generated in the medicine receiving chamber 10 by friction while the medicine receiving chamber 10 moves while the entire area of the opening 10b of the medicine receiving chamber 10 is in communication with the opening 5a of the medicine storage chamber 5. Therefore, the filling rate of the powder medicine M into the medicine receiving chamber 10 can be increased.

また、本実施形態では、上側本体部2Aと下側本体部3Aとの相対スライドによって薬剤受室10が開口部5aの下を通り抜けることにより非連通状態から連通状態を経て非連通状態とに切り替わる粉末薬剤Mの薬剤受室10への導入および擦り切りのストロークを、少なくとも2回以上行った後に、薬剤受室10が排出位置Pdに到達するように構成してある。   Further, in the present embodiment, the medicine receiving chamber 10 passes under the opening 5a by the relative slide between the upper main body 2A and the lower main body 3A, thereby switching from the non-communication state to the non-communication state through the communication state. The configuration is such that the drug receiving chamber 10 reaches the discharge position Pd after the introduction of the powder drug M into the drug receiving chamber 10 and the stroke of scraping are performed at least twice or more.

このように、薬剤受室10への粉末薬剤Mの導入ならびに擦り切りのストロークを複数回行うことで、薬剤受室10に粉末薬剤Mを充填する機会が増える分、粒子間の隙間をより均一にすることができ、充填率を向上することができる。   As described above, by introducing the powder medicine M into the medicine receiving chamber 10 and performing the scraping stroke a plurality of times, the opportunity for filling the medicine receiving chamber 10 with the powder medicine M is increased, and the gaps between the particles are made more uniform. And the filling rate can be improved.

また、本実施形態では、相対スライド方向の異なる複数(本実施形態では逆方向に2回)のストロークの後に、薬剤受室10が排出位置Pdに到達するように構成してある。   In the present embodiment, the medicine receiving chamber 10 reaches the discharge position Pd after a plurality of strokes having different relative slide directions (twice in the opposite direction in the present embodiment).

薬剤受室10における粉末薬剤Mの充填状態の密度が当該薬剤受室10の移動方向に依存する場合がある。よって、本実施形態のように、相対スライド方向の異なる複数のストロークの後に薬剤受室10を排出位置Pdに到達させるようにすれば、薬剤受室10における充填状態のばらつきを減らすことができる。なお、本実施形態では、逆方向に2回のストロークを経て排出位置Pdに到達させるようにしたが、もちろん、ストロークを2回以上設定することができるし、逆方向以外の異なる方向(交差方向)とすることもできる。   In some cases, the density of the powder medicine M filled in the medicine receiving chamber 10 depends on the moving direction of the medicine receiving chamber 10. Therefore, if the medicine receiving chamber 10 is made to reach the discharge position Pd after a plurality of strokes having different relative slide directions as in the present embodiment, the variation in the filling state in the medicine receiving chamber 10 can be reduced. In the present embodiment, the discharge position Pd is reached through two strokes in the reverse direction, but, of course, the stroke can be set twice or more, and different directions other than the reverse direction (cross direction) ).

また、本実施形態では、上述したように、相対スライド方向が逆となる2回のストロークの後に、薬剤受室10が排出位置Pdに到達するように構成してある。   In the present embodiment, as described above, the medicine receiving chamber 10 reaches the discharge position Pd after two strokes in which the relative slide directions are reversed.

擦り切りにより、薬剤受室10の開口部5aに対する移動方向の先方側(前側)に、充填率の低い領域が生じる場合がある。よって、本実施形態のように、相対スライド方向が逆となる2回のストロークの後に、薬剤受室10を排出位置Pdに到達させるようにすれば、当該2回のストロークで前後が逆になるため、薬剤受室10における充填状態のばらつきを減らすことができる。   By abrasion, a region with a low filling rate may occur on the front side (front side) in the moving direction with respect to the opening 5a of the medicine receiving chamber 10. Therefore, as in this embodiment, if the medicine receiving chamber 10 is made to reach the discharge position Pd after two strokes in which the relative slide directions are reversed, the front and back are reversed in the two strokes. Therefore, the variation in the filling state in the medicine receiving chamber 10 can be reduced.

また、本実施形態では、上側本体部2Aと下側本体部3Aとの相対スライドによって薬剤受室10が開口部5aを跨いで往復できるように構成した。   Moreover, in this embodiment, it comprised so that the chemical | medical agent receiving chamber 10 could reciprocate across the opening part 5a by the relative slide of 2 A of upper side main-body parts, and 3 A of lower side main parts.

すなわち、薬剤受室10が開口部5aを跨ぐ一つの経路を往復するように構成することで、相対スライド方向が逆となる2回のストロークの後に排出位置Pdに到達させる構成を比較的簡素な構成として得ることができる。また、排出位置Pdと非使用状態での待機位置Paとを開口部5aに対して相対スライド方向の同じ側に設定することができ、使用者に、薬剤受室10が待機位置Paにある状態から上側本体部2Aと下側本体部3Aとを一往復相対スライドさせる動作を、投与前の準備操作としてより確実に認識させることができる。   That is, by configuring the medicine receiving chamber 10 to reciprocate along one path across the opening 5a, the configuration for reaching the discharge position Pd after two strokes in which the relative slide directions are reversed is relatively simple. It can be obtained as a configuration. In addition, the discharge position Pd and the standby position Pa in the non-use state can be set on the same side in the relative sliding direction with respect to the opening 5a, and the user is in a state where the medicine receiving chamber 10 is at the standby position Pa. Therefore, the operation of sliding the upper main body 2A and the lower main body 3A by one reciprocal relative movement can be more reliably recognized as a preparatory operation before administration.

また、本実施形態では、上側本体部2Aおよび下側本体部3Aのうちいずれか一方(本実施形態では上側本体部2A)と連動してスライドし、粉末薬剤Mおよび空気の排出口6fを開閉するスライドカバー4Aを設け、このスライドカバー4Aを排出口6fを閉じる位置から開く位置にスライドさせることにより、当該スライドカバー4Aに連動して上記一方(本実施形態では上側本体部2A)を他方(本実施形態では下側本体部3A)に対して相対スライドさせるようにした。   In the present embodiment, sliding is performed in conjunction with either one of the upper main body 2A and the lower main body 3A (in this embodiment, the upper main body 2A), and the powder medicine M and the air outlet 6f are opened and closed. The slide cover 4A is provided, and the slide cover 4A is slid from the position where the discharge port 6f is closed to the position where the discharge port 6f is opened, so that the one (upper main body 2A in the present embodiment) is linked to the other ( In this embodiment, it is made to slide relative to the lower main body 3A).

このため、上側本体部2Aと下側本体部3Aとを相対スライドさせる操作と、スライドカバー4Aを開ける操作とを別個に設定する場合に比べて投与前の準備操作の手間を省くことができる。また、スライドカバー4Aによって排出口6fを開く操作は、投与前の準備操作として認識しやすいため、この操作によって上側本体部2Aと下側本体部3Aとを相対スライドさせることで、当該相対スライドをより確実に行わせやすくなるという利点もある。   For this reason, compared with the case where the operation of sliding the upper main body 2A and the lower main body 3A relative to each other and the operation of opening the slide cover 4A are set separately, the labor of the preparatory preparatory operation can be saved. In addition, since the operation of opening the discharge port 6f by the slide cover 4A is easily recognized as a preparatory operation before administration, the relative slide is performed by relatively sliding the upper main body 2A and the lower main body 3A by this operation. There is also an advantage that it is easy to make it more reliable.

また、本実施形態では、相対スライド方向が逆となる2回の前記ストロークの後に、薬剤受室10が排出位置Pdに到達するように構成し、スライドカバー4Aを排出口6fを開く方向にスライドさせることで第1回目の前記ストロークが得られ、スライドカバー4Aと上側本体部2Aおよび下側本体部3Aのうち当該スライドカバー4Aと連動する一方(本実施形態では上側本体部2A)とを分離して、当該一方のみをスライドカバー4Aに連動して移動する前の位置、すなわち待機位置Paに向けて戻すことにより、第1回目の前記ストロークとは逆方向の第2回目のストロークが得られるようにした。   In the present embodiment, the medicine receiving chamber 10 is configured to reach the discharge position Pd after two strokes in which the relative slide directions are reversed, and the slide cover 4A is slid in the direction to open the discharge port 6f. By doing so, the first stroke is obtained, and one of the slide cover 4A, the upper main body 2A, and the lower main body 3A that is linked to the slide cover 4A (the upper main body 2A in this embodiment) is separated. Then, the second stroke in the direction opposite to the first stroke is obtained by returning only one of the two toward the position before moving in conjunction with the slide cover 4A, that is, the standby position Pa. I did it.

すなわち、スライドカバー4Aを開く操作によって上側本体部2Aと下側本体部3Aとの相対スライドを生じさせた後、連動状態を解消して、スライドカバー4Aを開いた状態に維持したまま、これに連動させた上側本体部2Aおよび下側本体部3Aのうち一方(本実施形態では上側本体部2A)のみを元の位置に戻すという、比較的簡単な操作によって逆方向に相対スライドさせ、薬剤受室10への粉末薬剤Mの充填率を向上することができる。   That is, after the slide cover 4A is opened, the upper main body 2A and the lower main body 3A are caused to slide relative to each other, and then the interlocking state is canceled and the slide cover 4A is maintained in the open state. A relatively simple operation of returning only one of the interlocked upper main body 2A and lower main body 3A (in this embodiment, the upper main body 2A) to the original position is relatively slid in the opposite direction to receive the medicine. The filling rate of the powdered medicine M into the chamber 10 can be improved.

また、本実施形態では、スライドカバー4Aと上側本体部2Aおよび下側本体部3Aのうち一方(本実施形態では上側本体部2A)とを係合して連動させる係合構造8を設け、スライドカバー4Aの排出口6fを開く動作に連動する相対スライドにより薬剤受室10が開口部5aの下を通過した後に、スライドカバー4Aに連動して動く上記一方(本実施形態では上側本体部2A)のみを他方(本実施形態では下側本体部3A)に係止する係止構造として機能する案内構造7を設け、当該案内構造7において上記一方が他方に係止されることにより、係合構造8によるスライドカバー4Aと上記一方(本実施形態では上側本体部2A)との係合が解除されるようにした。   In the present embodiment, an engagement structure 8 is provided for engaging and interlocking the slide cover 4A with one of the upper body portion 2A and the lower body portion 3A (in this embodiment, the upper body portion 2A). The above-mentioned one (in this embodiment, the upper main body 2A) that moves in conjunction with the slide cover 4A after the medicine receiving chamber 10 has passed under the opening 5a by a relative slide that is linked to the operation of opening the discharge port 6f of the cover 4A. Is provided with a guide structure 7 that functions as a locking structure that locks only the other (the lower main body portion 3A in the present embodiment). The engagement between the slide cover 4A and the above-mentioned one (the upper main body 2A in this embodiment) is released.

このため、スライドカバー4Aとこれに連動する上記一方(本実施形態では上側本体部2A)とを、比較的容易な操作で分離させることができる。   For this reason, the slide cover 4A and the above-described one (the upper body portion 2A in this embodiment) can be separated by a relatively easy operation.

また、本実施形態では、開口部5aを薬剤受室10の開口部(下側開口部)10bより広くし、開口部5aと薬剤受室10との連通状態で開口部10bが開口部5a内に収まる状態が得られるようにした。   In the present embodiment, the opening 5a is wider than the opening (lower opening) 10b of the medicine receiving chamber 10, and the opening 10b is located in the opening 5a in a communication state between the opening 5a and the medicine receiving chamber 10. The condition that fits in is obtained.

このため、相対スライドの際に、薬剤受室10が開口部5aに臨んでいる区間をより長くとることができて、薬剤受室10への粉末薬剤Mの充填効率を高めることができる。   For this reason, during relative sliding, the section in which the medicine receiving chamber 10 faces the opening 5a can be made longer, and the filling efficiency of the powder medicine M into the medicine receiving chamber 10 can be increased.

また、本実施形態では、開口部5aに同時に連通しかつ排出位置Pdで同時に空気通路6Aに臨む複数の薬剤受室10としての小孔10aを設けた。   In the present embodiment, a plurality of small holes 10a serving as a plurality of medicine receiving chambers 10 that communicate with the opening 5a at the same time and simultaneously face the air passage 6A at the discharge position Pd are provided.

薬剤受室10を一箇所に大きく設けた場合には、当該薬剤受室10内の他の領域に存在する粉末薬剤Mの動きの影響を受けて粉末薬剤Mの充填率のばらつきが生じやすくなる。この点、本実施形態では、複数の小孔10aを一つの薬剤受室10として、細分化して(分散して)設けることで、他の領域からの影響を抑制して充填率を向上することができる。   When the medicine receiving chamber 10 is provided large in one place, the filling rate of the powder medicine M is likely to vary due to the influence of the movement of the powder medicine M existing in other regions in the medicine receiving chamber 10. . In this regard, in the present embodiment, by providing a plurality of small holes 10a as one medicine receiving chamber 10 in a subdivided (distributed) manner, the influence from other regions is suppressed and the filling rate is improved. Can do.

また、本実施形態では、開口部5aに同時に連通する複数の小孔10aの開口部10bの全てが開口部5a内に収まる状態が得られるようにした。   Further, in the present embodiment, a state is obtained in which all of the openings 10b of the plurality of small holes 10a communicating with the opening 5a at the same time are accommodated in the openings 5a.

複数の小孔10aが別々のタイミングで開口部5aに連通すると、粉末薬剤Mを各小孔10aに充填する際の自重による圧力にばらつきが生じ、充填率がばらつく虞がある。この点、本実施形態では、複数の小孔10aの全てが開口部5aに連通する状態が得られるようにしたため、各小孔10aに対する粉末薬剤Mの充填圧力を均一化できて、充填ばらつきを低減して、充填率を向上することができる。   When the plurality of small holes 10a communicate with the opening 5a at different timings, there is a possibility that the pressure due to the weight of the powder medicine M when filling the small holes 10a varies and the filling rate varies. In this respect, in the present embodiment, since a state where all of the plurality of small holes 10a communicate with the opening 5a can be obtained, the filling pressure of the powder medicine M to each small hole 10a can be made uniform, and filling variation is caused. It can reduce and a filling rate can be improved.

また、本実施形態では、上側本体部2Aの開口部5aに対して相対スライド方向にずれた位置または下側本体部3Aの薬剤受室10に対して相対スライド方向にずれた位置に、粉末薬剤Mを回収する薬剤回収室9を形成した。   In the present embodiment, the powder medicine is placed at a position displaced in the relative sliding direction with respect to the opening 5a of the upper body portion 2A or at a position displaced in the relative sliding direction with respect to the medicine receiving chamber 10 of the lower body portion 3A. A drug recovery chamber 9 for recovering M was formed.

上側本体部2Aの下面2aと下側本体部3Aの上面3aとの間に粉末薬剤Mが残存すると、これら下面2aおよび上面3a間に隙間が生じて、シール性の低下につながる虞がある。この点、本実施形態では、薬剤回収室9を設けて、下面2aおよび上面3a間に付着した粉末薬剤を回収することで不具合を抑制することができる。   If the powder medicine M remains between the lower surface 2a of the upper main body portion 2A and the upper surface 3a of the lower main body portion 3A, a gap may be generated between the lower surface 2a and the upper surface 3a, leading to a decrease in sealing performance. In this regard, in the present embodiment, it is possible to suppress the problem by providing the drug recovery chamber 9 and recovering the powder drug adhered between the lower surface 2a and the upper surface 3a.

また、本実施形態では、非使用状態から上側本体部2Aと下側本体部3Aとを一往復相対スライドさせることにより、薬剤受室10を上側開口部の下を往復して通過させて排出位置Pdに到達させるように構成した。   In the present embodiment, the upper body 2A and the lower body 3A are reciprocated relative to each other from the non-use state, thereby causing the medicine receiving chamber 10 to reciprocate under the upper opening to be discharged. It was configured to reach Pd.

このため、シンプルな一往復の相対スライド操作によって、薬剤受室10への粉末薬剤Mの導入および擦り切り時の充填率の低下を抑制し、粉末薬剤Mの投与量の精度を高めることができる。   For this reason, a simple one-way reciprocal relative slide operation can suppress the reduction of the filling rate when the powder medicine M is introduced into the medicine receiving chamber 10 and is worn out, and the accuracy of the dosage of the powder medicine M can be increased.

図22,図23は、薬剤受室の変形例を示す図であって、(a)は平面図、(b)は一部の断面図である。図22は、短冊状に複数の小孔10aを配列して薬剤受室10Bを構成した例を示し、図23は、図9の例に対して薬剤受室10Cを成す複数の小孔10aの数ならびに配列を変更したものである。これら変形例によっても、同様の効果を得ることができる。なお、図22の例の場合、相対スライド方向は図22の左右方向とするのが好適である。   22 and 23 are views showing a modified example of the medicine receiving chamber, in which (a) is a plan view and (b) is a partial cross-sectional view. FIG. 22 shows an example in which a plurality of small holes 10a are arranged in a strip shape to form a medicine receiving chamber 10B, and FIG. 23 shows a plurality of small holes 10a forming the medicine receiving chamber 10C with respect to the example of FIG. The number and sequence are changed. Similar effects can be obtained by these modified examples. In the case of the example in FIG. 22, it is preferable that the relative slide direction is the left-right direction in FIG.

図24は、薬剤貯留室5の変形例を示す縦断面図である。この変形例では、開口部5aの上側にメッシュ12を設けてある。このようにメッシュ12を設けることで、粉末薬剤Mの自重による影響を軽減し、開口部5aの位置による充填率のばらつきを抑制することができる。また、粉末薬剤Mが何らかの原因で凝集した場合に、当該凝集した粉末薬剤Mをメッシュ12上に留め、薬剤受室10に導入されるのを抑制することができる。   FIG. 24 is a longitudinal sectional view showing a modification of the medicine storage chamber 5. In this modification, the mesh 12 is provided above the opening 5a. By providing the mesh 12 in this manner, the influence of the weight of the powder medicine M can be reduced, and variation in the filling rate depending on the position of the opening 5a can be suppressed. In addition, when the powder medicine M is aggregated for some reason, the agglomerated powder medicine M can be retained on the mesh 12 and suppressed from being introduced into the medicine receiving chamber 10.

(第実施形態)図25は、本発明の第実施形態にかかる粉末薬剤投与器を示す。図25は、薬剤受室が薬剤貯留室に対して相対スライド方向の一方側にある状態を示す図であって、(a)は平面図、(b)は側面図である。また、図26は、薬剤受室が薬剤貯留室に対して相対スライド方向の他方側にある状態を示す平面図である。 ( Second Embodiment) FIG. 25 shows a powder drug administration device according to a second embodiment of the present invention.
