前記上本体(11)に対して前記下本体(12)を上方向から見て右方向に回動させたときに、
前記下本体(12)に加えられた右方向の回転力が、この下本体(12)を介してポス ト(12ps)に伝達され、これによりこのポスト(12ps)が前記下本体(12)と一体となって右方向に回転されるとともに、さらにポスト(12ps)から前記押し上げナット(12n)に回転力が伝達され、これによりこの押し上げナット(12n)が前記下本体(12)および前記ポスト(12ps)と一体となって右方向に回転され、さらに押し上げナット(12n)が一体となって右方向に回転されるときに、前記鋸歯歯車(12g)および前記押し上げシャフト(12s)の連結体が前記外郭の中心軸を中心として右方向に公転され、

【0020】
【発明の実施の形態】
本発明の粉末物質の定量を分取する手段は図1に最も簡素な形状として示されている。本発明の図面において「上下左右」は説明の便宜上の表現である。更に、本願明細書ではマウスピースの位置及び噴射ノズルの位置する側を「上方」と称することがある。
【0021】
また、最も簡素で原理的であり、各部又は各部材を原則として連動関係無しに作動させる様に編成された機構として所定量の粉末を送り出し部へ繰り返して移送し得る容器の例に加えて、最も有用な例として所定量の粉末薬剤を繰り返して口腔内へ投与し得る吸入キット並びにその他の体腔内例えば鼻腔内へ噴射及びその他処置を要する部位へ噴射する噴射投与キットについて以下に説明する。
【0022】
図1の(a)は口腔内への所定量の粉末薬剤の吸入キットとして用い得るが、最も簡素で原理的な部材及び部品で編成された所定量の粉末の繰返し送り出し可能な容器である。勿論、自力で吸入する能力を保有しない使用者の為には図1の(b)における様に圧送用の加圧気体を収容した圧送気体収容部材(Bb)をその気体導入孔(Ah)に付設して「吸入キット」を「噴射投与キット」に変更することもできる。その構成は概略的には上端部に位置する吸入部(Am)とその下端から下方へ向けて伸びる基幹部(Ak)とであり、基幹部(Ak)の片側にには筒状部(Ac)が形成されると共に、筒状部材(Ac)の下端に続いて下方進行禁止ラチェット部(Ar)が形成されている。
【0023】
筒状部(Ac)内には下方から圧縮部材(Ap)が装入されて、筒状部(Ac)内に収容された粉末薬剤を圧縮する。その圧縮力を受け止めるものは吸入部(Am)の内壁から張り出した仕切壁(Amw)の下面である。仕切壁(Amw)の下面と筒状部(Ac)の上端との間に計量部材(Av)が嵌装されており、左右に滑動可能であると共に、可能な限り両部に密接した状態で嵌装されている。
【0024】
筒状部(Ac)内に下方か挿入されている圧縮部材(Ap)はその下面から下方へ伸びる圧縮部材(Ap)を押し上げる棒状部材(As)で上方へ押し動かされて圧縮作用を果たす。しかし、棒状部材(As)は定量的に圧縮部材(Ap)を上方へ動かすが下方へ戻ってはならない。それを担保する為には棒状部材(As)の下端域が下方進行禁止ラチェット部(Ar)に係合する為の1個以上の係合歯(Asr)を備えている。
【0025】
図1の(a)において、吸入部(Am)は所謂マウスピースであって、その開口(Ami)は断面積の約半分は仕切壁(Amw)で閉塞され、その反対側に口腔内への輸送用気体の流通孔(Amd)が穿設されている。この流通孔(Amd)の形状はそれと平行に設けられている筒状部材(Ac)であって粉末薬剤を収容すると共に、圧縮にも寄与する筒状部材(Ac)の上端の開口の形状と一致することが重要である。
【0026】
図1の(a)において計量部材(Av)は細長い板状の部材であって、その略中央部に透孔(Avh)が穿孔されている。この計量部材(Av)は上記のマウスピース(Am)の基底部と基幹部(Ak)の上端との接続部に穿設された挿通孔内を左右に滑動する。計量部材(Av)に穿設された透孔(Avh)は計量孔として働くもので、筒状部材(Ac)内に収容された粉末薬剤が圧縮部材(Ap)によって計量孔(Avh)中に押し込まれると、それが所定量となる。
【0027】
この時点で計量部材(Av)の末端に設けられたヘッド(Ave)が図において右側へ押されることによってヘッド(Ave)の根元まで挿通孔内へ押し込まれると、その計量孔(Avh)が右方へ移動して輸送用気体の流通孔(Amd)の位置に一致する様に計量孔(Avh)の位置及び計量部材(Av)の長さが設定されることが重要である。
【0028】
その結果、その計量孔(Avh)内に圧縮充填されていた粉末薬剤が気体流通孔(Amd)内に移動する。次に使用者がマウスピース(Am:吸入部における開口)を自己の口に入れて強く息を吸えば、気体導入孔(Ah)から勢い良く吸い込まれた空気が粉末薬剤を吹き上げて輸送しながらマウスピース口(Ami)経由で口内へ送り込む。
【0029】
この為には、気体導入孔(Ah)の向きと気体流通孔(Amd)の最奥部との形状とを重質の粉末薬剤をも十分に吹き上げ得る様に選択することが重要である。図1では気体導入孔(Ah)が比較的小径に形成されると共に、気体流通孔(Amd)の最奥部に向けられていると共に、該最奥部が凹曲面に成形されている。
【0030】
圧縮部材(Ap)の定量圧縮作用を担保する為には、圧縮部材(Ap)の下方から下方へ向けて伸びる棒状部材(As)の下端域に刻設された係合歯とその逆戻りを禁止しながら所定距離づつ上方へ進める為の係止手段、図1では下方移動禁止ラチェット(Ar)とが協働することが必要である。
【0031】
勿論、この下方移動を禁止しながら所定距離づつ上方へ移動させる為の係止手段はラチェットとそれに係合する係合歯との組合せに限らず他の係止手段であっても良く、例えば基幹部に所定間隔毎に穿設された小孔と該小孔に挿通させる為に棒状部材(As)の下端域に植設された係止ピンとの組合せ等でも差支え無い。
【0032】
図1の(b)に示された容器(B)は噴射ノズル(Bj)及び圧送気体収容部材(Bb) が図1の(a)に示された容器(A)とは異なっている。図1の(b)に示された容器(B)は粉末薬剤の口腔以外の体腔内例えば、鼻腔内への噴射投与キットとして用い得るものであって、各部に付与された符号の大部分は図1の(a)における符号の最初を「A」から「B」へ差し替えればその儘図1の(a)に対応する。その際には、図1の(a)には存在しない部分(部材)だけに「B」で始まる別異の符号を付与すれば足りる。
【0033】
図1の(b)に示された容器(B)は上述の様に口腔以外の体腔例えば、「鼻」を意図したものである。従って、その使用に当たっては粉末薬剤の噴射ノズル(Bj)を鼻腔内へ挿入し、ヘッド(Bve)を右方へ押して計量板(Bv)の計量孔(Bvh)の位置を噴射ノズル(Bj)内の気体流通路(Bji)の位置に一致させ、圧送気体送り出し部材(Bb)の頚部に設けられたバルブ(不図示)を開いて加圧気体を気体導入孔(Bh)から気体流通路(Bji)へ送り込む。
【0034】
この粉末薬剤の噴射キット(B)が使用者の立位で下方から噴射投与される形態で用いられる場合には特に問題は生じ難い。処が、使用者が横臥位で用いる場合には計量部材(Bv)が移動した時点で直ちに加圧気体を導入することが望ましい。しかし、これは意外に困難である。その困難を解消する為には、計量部材(Bv)の移動とバルブの開放とを連動させる様にキットを構成することが好ましい。その具体的構成としては、計量部材(Bv)のヘッド(Bve)とは反対側の末端が突出するから、これにバルブに付設した梃子を押し動かさせる連動形態でも十分である。
【0035】
<<最も実用的で高信頼性を備えた粉末薬剤の投与キット>>
本発明の粉末薬剤吸入又は噴射投与キット(1)(「本発明のキット」と略称することがある)の好適態様について以下に図面に基づいて具体的に説明する。図2は本発明の吸入又は噴射投与キットの状態を示し、図2の(a)は原寸外観、図2の(b)は該キット(1)のオーバーキャップ(C)を取り外し状態の原寸外観及び図2の(c)は該キットの縦断面を示す。
【0036】
詳細な構成は図3に示された図2の(c)の拡大縦断面図に基づいて説明する。図3においては、本発明のキット(1)が細い末端を上方へ向けた状態図示されており、図3は本発明のキット(1)の拡大縦断面図ではあるが、長軸を含む単一の平面による縦断面図ではなく、図3の右半分は紙面に含まれる平面による縦断面図、左半分は該平面に対して60度起き上がった別異の平面による縦断面図である。
【0037】
なお、図3だけでは構造の細部が解り難い場合には、図4に示された横断面図をも参照することがある。即ち、図4の各図[(a)〜(d)]は本発明のキットを処々で切断(輪切り)にした横断面図である。上記の左半分の断面図を呈する切断平面が右半分とは異なる平面である理由は逆転が禁止された鋸歯歯車(12g)の軸−−それは押し上げシャフト(12s)の軸と共通−−の縦断面を示すという目的にある。

再び、図3において(C)はオーバーキャップである。本発明のキット(1)の上本体(11)を保護すると共に汚染等に対しても上本体(11)を隔離する機能を果たす。オーバーキャップ(C)の下端域内壁には本発明のキット(1)の下本体(12)の上端域外壁の係合手段と係合する手段が設けられている。係合手段として最も通常的なものは雌ネジである。しかし、係合手段は別にネジに限定されず、他の手段例えば、バイヨネットマウントでも差支えは無い。以下はオーバーキャップ(C)を取り外した場合を説明するものである。
【0039】
<<マウスピース(11m)>>
マウスピース(11m)は本発明のキットの最上端に位置し、円筒状であってその外壁が通常は上方へ向けて稍細く作成されている。その先細形状の意義はマウスピース(11m)が吸入者の口に挿入され為の便宜から来る。その内壁(11mi)中段から障壁(11mb)が略半径の長さまで張り出している。
【0040】
障壁(11mb)の機能はキット内部で計量されて噴射待ちの粉末薬剤がキットの右側を下にした倒立状態で使用される前に無為に崩れ出る事態及びそれに続く吸入時に粉末薬剤が気体に浮遊せずに急激に吐出する事態を防止することにある。
【0041】
マウスピース(11m)の下端域は本発明のキット(1)の上本体(11)上端域に内嵌されている。両部材を係止させる手段は図示の螺合に限らない。
<<上本体(11)>>
上本体(11)は円筒であって、その上端域外壁が通常は先細に作成されていると共に、その下段右側壁に気体導入孔(11h)が設けられている。気体導入孔(11h)の機能は吸入用の輸送気体の導入口を提供することにある。また、上本体(11)の左側壁は母線に平行に長く切り欠かれていることが図示されているが、その機能は本発明のキット(1)内部に組み込まれた内筒(11i)内に本発明のキット(1)の使用回数又は内筒(11i)の内部に収容された粉末薬剤の残量をキット外部から透視可能にすることにある。本発明のキット(1)の使用回数又は収容された粉末薬剤の残量をキット外部から検知可能にする手段としては、上記の図示された例に限らず別の手段であってもよい。以下に上本体(11)内に収容された各種部材について説明する。
【0042】
<<包括シリンダー(11g)>>
包括シリンダー(11g)は上本体(11)の直ぐ内側に装着された円筒であってその上端域に拡径部(11ge)を備え、拡径部(11ge)の上縁で計量板押さえ(11b)の下面を支承すると共に拡径部(11ge)にはその上縁から切欠き(11gc)を通常は4個備えている。この切欠 (11gc)は後記の計量板押さえ(11b)の鍔(11bc)と嵌合する。更に拡径部(11ge)内壁には数個の左回転禁止ラチェット(11ger)を備えている。左回転禁止ラチェット(11ger)は後記の計量板(11v)の周縁に設けられた左回転禁止ラチェット(11vr)と係合してその左回転を禁止する。
【0043】
包括シリンダー(11g)はその下端にも切欠き(11gc)を(本発明の例では幅45度で4個)備え、それによって後記の押し上げナット(12n)の拡径部(12ne)外壁から張り出した鍔(12nf)に設けられた切欠き(12nfc)と嵌合して一体として回動する。
【0044】
<<計量板ラチェット(11r)、計量板押さえ(11b)、計量板(11v)>>計量板ラチェット(11r)は円板でその外周に左回転禁止ラチェット(11rb)を複数個通常は3個備えると共に2個以上の透孔(11rh)を備えている。透孔(11rh)の個数及び位置は後記の計量板(11v)に設けられた計量孔(11vh)の個数及び位置と一致する。計量板ラチェット(11r)は上本体(11)内部の大径部上端に装着されている。計量板ラチェット(11r)の機能はそれと同軸上に位置する後記の計量板(11v)を伴って右回転させることにある。その目的で上記の計量板ラチェット(11r)の下面中心部には円柱状の突起(11rp)が設けられ、その内部に例えば3角形の凹窩(11rpc)が設けられている。凹窩(11rpc)の形状は4角形でもよいが、該部へ収容される棒状体の回転を禁止する為には5角形以上は避けることが好ましい。
【0045】
計量板押さえ(11b)は上記の計量板ラチェット(11r)の下面に接して設けられ、円板であってその周縁に左回転禁止ラチェット(11bb)を備えることに加えて、その上面周縁から外側へ張り出すと共に上方へも盛り上がった大径の鍔(11bf)を備えている。
【0046】
鍔(11bf)の下面からその厚さの通常約1/2以下の切欠きが通常は複数個、図示の態様では4個設けられている。更にその円板域には中心部に小径の透孔(11bhs)及びそれと同一半径上の外側に大径の円形透孔(11bhb)が穿設されている。円形透孔(11bhb)の直径及び位置は上記の計量板ラチェット(11r)に穿設された透孔(11rh)のそれらと同一とする。
【0047】
小径透孔(11bhs)及びそれと同一半径上の外側に穿設された大径の円形透孔(11bhb)との間は連通されており、連通部の幅は小径透孔(11bhs)と同一で十分である。この連通部の機能は計量板押さえ(11b)の下面に接して位置するべき計量板(11v)の上面から伸びる末広 (11vx)の大径部(11vxb)を貫通させると共にその小径部(11vxs)を小径の透孔(11bbhs)へ移動させて支承することにある。
【0048】
計量板(11v)は円板で、それを貫通して計量孔(11vh)が通常は3個穿孔されていると共にその頂面中心から立上がる末広軸(11vx)を備えている。頂面中心から立上がる末広 (11vx)の大径部(11vxb)は例えば三角形断面であって、計量板ラチェット(11r)の下面から伸びる円柱突起(11rp)の中心に穿設された凹窩(11rpc)に嵌合する。従って、計量板(11v)は上記の計量板ラチェット(11r)と一体になって右へ120度づつ間欠的に回転する。また、末広軸(11vx)の小径部(11vxs)は円形断面であって計量板押さえ(11b)の小径透孔(11bhs)に収容される。
【0049】
計量板(11v)はその周縁に左回転禁止ラチェット(11vr)を備え、左回転禁止ラチェット(11vr)は包括シリンダー(11g)の拡径部(11ge)内壁に設けられた左回転禁止ラチェット(11ger)と係合すると共に包括シリンダー(11g)から回動力を与えられて、右へ120度づつ回転する。
【0050】
計量板(11v)の機能は内筒(11i)内に収容された粉末薬剤を計量することにある。即ち、内筒(11i)内に嵌装されているピストン(12p)が粉末薬剤を計量板(11v)の計量孔(11vh)内に圧縮装填する。計量板(11v)に穿設された計量孔(11vh)が通常は3個であること及びそれらの相互位置は図4の(b)及び図4の(c)に示されている。
【0051】
ここで、図4の(a)は本発明のキット(1)を上記の計量板(11v)を横断する切断線A−Aで切断して現れる形状を矢印方向へ向かって見上げた状態であり、図4の(b)は本発明のキット(1)を上記の気体導入孔(11h)を横断する切断線B−Bで切断して現れる形状を矢印方向へ向かって見上げた状態である。
【0052】
尤も、粉末薬剤の計量は計量板(11v)の裏側(上面)に密接した計量板押さえ(11b)との共同作業である。即ち、計量板押さえ(11b)が計量板(11v)の裏側から粉末薬剤を堰留めてピストン(12p)による押圧力を効果的に粉末薬剤に及ぼし得る様にする機能を果たす。
【0053】
<<内筒(11i)>>
内筒(11i)は筒状の部材でその内径はその全長において同一であって前記の計量孔(11vh)と同一である。内筒(11i)は上縁で計量板(11v)の下面に密接すると共に計量板(11v)の下面に密接し、その計量孔(11vh)に正対する。その機能は内部に粉末薬剤を収容することにある。
【0054】
内筒(11i)の下側からはピストン(12p)が挿入されている。ピストン(12p)の機能は粉末薬剤を所定量(所定距離)だけ押し上げることにある。しかし、ピストン(12p)は独自に上昇し得る訳ではなく、その内部に下流側から挿入された押し上げシャフト(12s)によって押し上げられる。とはいえ、この押し上げシャフト(12s)も後述の機構で押し上げられるものである。
【0055】
<<スクリュー収容円筒(11a)>>
図3では、上記の内筒(11i)に平行な円筒であってスクリュー収容円筒(11a)が見受けられる。スクリュー収容円筒(11a)の機能は気体導入孔(11h)から導入された輸送気体を粉末薬剤と混合してマウスピース(11m)から噴出させる為に輸送する気体流通路でもある。その為に、スクリュー収容円筒(11a)の下段右側で気体導入孔(11h)と対応位置に開口(11ah)を備えている。
【0056】
このスクリュー収容円筒(11a)内には固定スクリュー(11s)が装着されている。固定スクリュー(11s)の機能は気流に旋回を与えて粉末薬剤を均一に浮遊させることにある。従って、固定スクリュー(11s)自体は回転しない。以上が本発明のキット(1)の上本体(11)に収容された必須部材を略尽くしている。そこで、以後は本発明のキット(1)の下本体(12)及びその内部に装着された部材について説明する。
【0057】
<<下本体(12)>>
図3によれば、下本体(12)は本発明のキット(1)の部材であって有底円筒形に作成されている。その上端域外壁に雄ネジが刻設されていてオーバーキャップ(C)の下端域内壁の雌ネジと係合していることは上述の通りである。下本体(12)の機能はその内部に回動筒(12r)及び押し上げナット(12n)を収容し、押し上げナット(12n)をその底板内壁から立上がるポスト(12ps)によって直接に回動させることにある。ポスト(12ps)は押し上げナット(12n)内部に圧入嵌着されている。
【0058】
<<回動筒(12r)>>
下本体(12)内部には先ず、その内壁に近接して回動筒(12r)が回動可能に装着されている。回動筒(12r)は上端域に拡径部(12re)を備えると共に拡径部(12re)の外壁中段に鍔(12rf)を突設させている。
【0059】
この鍔(12rf)の機能はその数カ所、本発明の例では4ヶ所の切欠き(12rfc)を備え、その幅は45度であって上本体(11)の下端の対応箇所に設けられた切欠き(11fc)と緊密に嵌合して上本体(11)と一体として回動することにある。
【0060】
更に、鍔(12rf)よりも上端に近い外壁にアンダーカット(12u)を突設させている。アンダーカット(12u)の機能は上本体(11)の下端域内壁に設けられた溝又は凹窩(11c)と係合することによって上本体(11)からの不時の脱離を阻止する恐れを一層少なくすることにある。
【0061】
回動筒(12r)の拡径部(12re)以外の外壁には数カ所に鍔(12rf)が設けられて、それらの周縁が下本体(12)の内壁に略接しながら回動容易な状態を実現している。鍔(12rf)の機能は摩擦低減にある。即ち、回動筒(12r)の外壁全面が下本体(12)の内壁に当接して回転する際に生ずる大き過ぎる摩擦抵抗を大幅に低減している。
【0062】
<<押し上げシャフト(12s)>>
回動筒(12r)の内部には、先ず押し上げシャフト(12s)が装着されている。押し上げシャフト(12s)の機能は左回転しながら上昇してピストン(12p)を押し上げることにある。即ち、回動筒(12r)は図4の(d)に示された様に回転しながら、その内壁に設けられた鋸歯縦溝(12a)(ラチェット突条)から回転力を鋸歯歯車(12g)に伝えてそれを回転させる。
【0063】
その寄与によって、押し上げシャフト(12s)は自身の外壁に刻設された雄左ネジと押し上げナット(12n)の貫通孔(12nh)内壁に刻設された雌左ネジとを係合させることによって、上昇への推進力を得る。ここで、上記の図4の(d)は本発明のキット(1)の下本体(12)をその底板に最も近接した切断線D−Dによって切断した断面を上方へ向かって見上げた際に現れる断面である。
【0064】
<<押し上げナット(12n)>>
図4の(c)によれば、押し上げナット(12n)の上端域は略円筒形の外郭とその外郭の内壁から突設する部分とで構成されている。この突設部分には同心の二重丸が見受けられるが、その中心の丸印は図3に示された上記の押し上げシャフト(12s)の外壁に刻設されたネジの谷円を示し、その外側の丸印は押し上げシャフト(12s)の外壁に刻設されたネジの山円を示す。図4の(c)は本発明のキット(1)の下本体(12)をその中段で切断線C−Cによって切断した断面を上方へ向かって見上げた際に現れる断面である。断面図4の(c)には押し上げナット(12n)の断面も含まれている。
【0065】
図4の(d)によれば押し上げナット(12n)の拡径部(12ne)よりも下部は複雑な形状に作成されている。即ち、その断面形状において中空半円形の右半分部分と中空四分円のとの結合からなる。これは実際には円筒の1/4周に相当する部分を切除した鋸歯縦溝(12a)つき管状体である。その鋸歯縦溝(12a)部分に鋸歯歯車(12g)及びその右回転を禁止する右回転禁止ラチェット(12gs)が係合した状態で押し上げシャフト(12s)が収納されている。
【0066】
なお、この鋸歯歯車(12g)の機能は上述の様に回動筒(12r)の右回動による駆動力を受けながら左回転することによって、回動筒(12r)の内壁を上昇することにある。即ち、回動筒(12r)の内壁に刻設された鋸歯縦溝(12a)から左向きの回転力を受ける。他方、中空半円断面の管状部分(12nr)内には下本体(12)の内壁底面から立上がるポスト(12ps)が下方から嵌着されている。ポスト(12ps)の機能は押し上げナット(12n)の自由回転を阻止して回動筒(12r)と一体になってそれを回動させると共に、下本体(12)が離脱しない様に固定することにある。
【0067】
<<キットを形成する材料>>
平均的に、本発明のキットを構成する部材が薬剤に直接に接触する場合及び使用者が手指で操作する場合には、その材質はポリオレフィン結晶性重合体が厚生省基準で要求される。しかし、それ以外の場合にはこの基準に限定される必然性が失われて、成形性、外観その他の点で最適の材質を用い得る筈である。
【0068】
次に、吸入用等の薬剤を用いる場合について本発明の多重筒機構を形成する材質を説明する。材質としてポリオレフィン結晶性重合体、中でもポリプロピレン結晶性重合体が好ましい部材は下掲の通りである:
◆オーバーキャップ(C)、マウスピース(11m)、上本体(11)、計量板押さえ(11b)、計量板(11v)、拡散スクリュー、スクリュー収容円筒(11a)、包括シリンダー(11g)、内筒(11i)、圧縮部材特にピストン(12p)及び下本体(12)に加えて、例外的ながら回動筒(12r);
また、成形性、外観その他の点で最適の材質で形成され得る部材は下掲の通りである:
◆計量板ラチェット(11r)、押し上げナット(12n)、鋸歯歯車(12g)及び押し上げシャフト(12s)。
【0069】
【作用】
本発明の図1に示された容器(A)及び容器(B)においては各部材間又は各部品間には連動関係が殆ど存在しないことから、ここでは説明を省略する。
【0070】
本発明の図3に示された吸入又は噴射投与キット(1)が用いられる場合の各部材相互の関係を説明すれば次の通りである。この時点ではオーバーキャップ(C)は取り外されていることを前提とする:
(1)下本体(12)を左に120度回動させるとその底板内面から立上がったポスト(12ps)が押し上げナット(12n)をその中心軸の廻りに左回転させる。その際には鋸歯歯車(12g)は右回転できない。その理由はそれが押し上げナット(12n)から伸びた右回転禁止ラチェット(12gs)によって右回転を阻止されていることに求められる。
【0071】
従って、鋸歯歯車(12g)は右回転せずに回動筒(12r)の内壁面に刻設された鋸歯縦溝(12a)を倒しながら左方向滑って行き、最終的には鋸歯縦溝(12a)の左端に到達する。この鋸歯縦溝(12a)は弾性に富む材質で形成されているからである。
【0072】
(2)下本体(12)を右に120度回動させると押し上げナット(12n)の下段に嵌着されたポスト(12ps)が押し上げナット(12n)をその中心軸の廻りに右回転させて原位置へ戻る。その際には鋸歯歯車(12g)が鋸歯縦溝(12a)と噛み合いながら左回転して、回動筒(12r)内壁を上昇しながら鋸歯縦溝(12a)の右端へ復帰する。
【0073】
その左回転の際には押し上げシャフト(12s)も左回転して押し上げナット(12n)の貫通孔内壁の雌左ネジと係合しながら上昇力を得る。その結果として、ピストン(12p)を所定高さだけ押し上げ、内筒(11i)中に収容された粉末(薬剤)が計量板(11v)及びその裏側の計量板押さえ(11b)の共働作用によって圧縮される。
【0074】
(3)上本体(11)の上端域に近い内壁面に設けられた1個以上の左回転禁止ラチェットはそこに装着される計量板ラチェット(11r)の周面に設けられた1個以上の左回転禁止ラチェットに係合して計量板ラチェット(11r)の左回転を禁止する。
【0075】
他方、上本体(11)の下縁に設けられた1個以上の切欠き(本発明の例では4個で幅45度)は回動筒(12r)の拡径部外壁に設けられた鍔(12rf)の下縁対応箇所に設けられた切欠き(11bc)と緊密に嵌合して、回動筒(12r)と一体になって回動する。
【0076】
(4)包括シリンダー(11g)の拡径部上縁に設けられた1個以上の切欠き(本発明の例では4個で幅45度)は計量板押さえ(11b)の鍔部下縁対応箇所に設けられた切欠き(11bc)と緊密に嵌合して、計量板押さえ(11b)と一体になって回動する。他方、包括シリンダー(11g)の下縁に設けられた1個以上の切欠き(本発明の例では4個で幅45度)は押し上げナット(12n)の鍔(12nf)の対応箇所に設けられた1個以上の切欠き(本発明の例では4個で幅45度)と緊密に嵌合して押し上げナット(12n)と一体になって回動する。
【0077】
【発明の効果】
本発明の最も簡素な所定量粉末の繰返し送り出し可能な容器は粉末薬剤にも適用可能である。そこで、その効果説明に代えて、以下に本発明の粉末薬剤の吸入又は噴射投与キットが下記の種々の効果を奏することを説明する:
(1)複合機構によれば、粉末を圧縮計量によって分取して毎回所定量の粉末を次工程へ移送することができる
(2)キットによれば、粉末薬剤を圧縮計量によって分画して毎回所定量の粉末薬剤を吸入者へ供給できる
(3)携帯容易なキットから簡単な操作によって毎回所定量の粉末薬剤を吸入者へ供給できる。このキットによる供給可能回数は現在の仕様では約60回に達する。更に多数回の供給も僅かな仕様変更によって容易に実現できる。
(4)その気体導入孔に圧送気体収容部材の供給口を接続すれば、容易に噴射投与キットへ変更可能である。

DETAILED DESCRIPTION OF THE INVENTION
The means for fractionating the powder substance of the present invention is shown in the simplest form in FIG. In the drawings of the present invention, “up, down, left and right” are expressions for convenience of explanation. Further, in the present specification, the position of the mouthpiece and the side where the injection nozzle is located may be referred to as “upward”.
[0021]
In addition to the example of a container that is the simplest and most basic, and can repeatedly transfer a predetermined amount of powder to the delivery part as a mechanism that is knitted to operate each part or each member in principle without any interlocking relationship, As the most useful examples, an inhalation kit that can repeatedly administer a predetermined amount of powdered medicine into the oral cavity and an injection administration kit that injects into other body cavities such as the nasal cavity and other sites requiring treatment will be described below.
[0022]
FIG. 1 (a) can be used as an inhalation kit for a predetermined amount of powdered medicine into the oral cavity, but is a container capable of repeatedly delivering a predetermined amount of powder organized by the simplest and basic members and parts. Of course, for users who do not have the ability to inhale by themselves, as shown in FIG.PumpingIt is also possible to change the “inhalation kit” to the “injection administration kit” by attaching the gas containing member (Bb) to the gas introduction hole (Ah). The structure is roughly composed of a suction part (Am) positioned at the upper end part and a trunk part (Ak) extending downward from the lower end thereof, and a cylindrical part is provided on one side of the trunk part (Ak).Material(Ac) is formed, and a downward progression prohibition ratchet portion (Ar) is formed following the lower end of the cylindrical member (Ac).
[0023]
Cylindrical partMaterialA compression member (Ap) is inserted into (Ac) from below, and the cylindrical portionMaterial(Ac) The powder medicine accommodated in is compressed. What receives the compressive force is the lower surface of the partition wall (Amw) protruding from the inner wall of the suction portion (Am). Bottom surface of partition wall (Amw) and cylindrical partMaterialA measuring member (Av) is fitted between the upper end of (Ac), is slidable to the left and right, and is fitted as close to both parts as possible.
[0024]
Cylindrical partMaterial(Ac) or downEtThe inserted compression member (Ap) is pushed upward by a rod-like member (As) that pushes up the compression member (Ap) extending downward from the lower surface thereof, and performs a compression action. However, the rod-shaped member (As) quantitatively moves the compression member (Ap) upward, but must not return downward. In order to secure it, the lower end region of the rod-shaped member (As) is provided with one or more engaging teeth (Asr) for engaging with the downward-progress-prohibited ratchet portion (Ar).
[0025]
In FIG. 1 (a), the inhalation part (Am) is a so-called mouthpiece, and its opening (Ami) is closed about half of the cross-sectional area by a partition wall (Amw). A transport gas circulation hole (Amd) is formed. The shape of the flow hole (Amd) is a cylindrical member (Ac) provided in parallel therewith, which accommodates the powdered drug and also contributes to the compression of the upper end of the cylindrical member (Ac). It is important to agree.
[0026]
In FIG. 1 (a), the measuring member (Av) is an elongated plate-like member, and a through hole (Avh) is perforated at a substantially central portion thereof. The measuring member (Av) slides left and right in the insertion hole formed in the connecting portion between the base of the mouthpiece (Am) and the upper end of the trunk (Ak). The through hole (Avh) drilled in the measuring member (Av) functions as a measuring hole, and the powder medicine accommodated in the cylindrical member (Ac) is put into the measuring hole (Avh) by the compression member (Ap). When pushed in, it becomes a predetermined amount.
[0027]
At this time, when the head (Ave) provided at the end of the measuring member (Av) is pushed to the right side in the drawing and pushed to the base of the head (Ave) into the insertion hole, the measuring hole (Avh) is moved to the right. It is important that the position of the measuring hole (Avh) and the length of the measuring member (Av) are set so as to move in the same direction and coincide with the position of the flow hole (Amd) of the transport gas.
[0028]
As a result, the powder medicine compressed and filled in the measuring hole (Avh) moves into the gas flow hole (Amd). Next, the user uses the mouthpiece (Am: Opening in the suction part) Into the mouth of his / herself and breathe in strongly, the air sucked in from the gas introduction hole (Ah) blows up the powder medicine and transports it through the mouthpiece mouth (Ami).
[0029]
For this purpose, it is important to select the direction of the gas introduction hole (Ah) and the shape of the innermost part of the gas flow hole (Amd) so that the heavy powder drug can be sufficiently blown up. In FIG. 1, the gas introduction hole (Ah) is formed to have a relatively small diameter, is directed to the innermost part of the gas flow hole (Amd), and the innermost part is formed into a concave curved surface.
[0030]
In order to secure the quantitative compression action of the compression member (Ap), the engagement teeth engraved in the lower end region of the rod-like member (As) extending from the lower side to the lower side of the compression member (Ap) and its reversal are prohibited. However, it is necessary to cooperate with a locking means for advancing upward by a predetermined distance, in FIG. 1, a downward movement prohibiting ratchet (Ar).
[0031]
Of course, the locking means for moving upward by a predetermined distance while prohibiting the downward movement is not limited to the combination of the ratchet and the engaging teeth engaged therewith, and may be other locking means. A combination of a small hole drilled at a predetermined interval in the portion and a locking pin planted in the lower end region of the rod-shaped member (As) for insertion through the small hole can be used.
[0032]
The container (B) shown in FIG. 1 (b) has an injection nozzle (Bj) andPumpingThe gas containing member (Bb) is different from the container (A) shown in FIG. The container (B) shown in FIG. 1 (b) can be used as a kit for injecting a powder medicine into a body cavity other than the oral cavity, for example, into the nasal cavity, and most of the reference numerals given to each part are If the first symbol in FIG. 1A is replaced from “A” to “B”, this corresponds to FIG. In that case, it is sufficient to give a different code starting with “B” only to a portion (member) that does not exist in FIG.
[0033]
The container (B) shown in FIG. 1B is intended for a body cavity other than the oral cavity, for example, the “nose” as described above. Therefore, when using it, the injection of powder medicinenozzleInsert (Bj) into the nasal cavity and push the head (Bve) to the right to position the measurement hole (Bvh) on the measurement plate (Bv)The injection nozzleMatch the position of the gas flow path (Bji) in (Bj)PumpingA valve (not shown) provided at the neck of the gas delivery member (Bb) is opened to send pressurized gas from the gas introduction hole (Bh) to the gas flow passage (Bji).
[0034]
When this powder medicine injection kit (B) is used in the form of injection administration from below at the user's position, problems are unlikely to occur. However, when the user uses the device in the lying position, it is desirable to introduce the pressurized gas immediately when the measuring member (Bv) moves. However, this is unexpectedly difficult. In order to eliminate the difficulty, it is preferable to configure the kit so that the movement of the measuring member (Bv) and the opening of the valve are interlocked. As its specific configuration, since the end of the measuring member (Bv) opposite to the head (Bve) protrudes, an interlocking form in which the lever attached to the valve is pushed and moved is sufficient.
[0035]
<< Most practical and highly reliable powder drug administration kit >>
Preferred embodiments of the powder medicine inhalation or injection administration kit (1) of the present invention (sometimes abbreviated as “kit of the present invention”) will be specifically described below with reference to the drawings. FIG. 2 shows the state of the inhalation or injection administration kit of the present invention. FIG. 2 (a) shows the full-scale appearance, and FIG. 2 (b) shows that the overcap (C) of the kit (1) is removed.TheThe full size appearance of the state and (c) of FIG. 2 show a longitudinal section of the kit.
[0036]
The detailed configuration will be described based on the enlarged longitudinal sectional view of FIG. 2 (c) shown in FIG. In FIG. 3, the kit (1) of the present invention has a narrow end directed upwardsoAlthough FIG. 3 is an enlarged longitudinal sectional view of the kit (1) of the present invention, it is not a longitudinal sectional view by a single plane including the major axis, but the right half of FIG. The left half is a vertical cross-sectional view of a different plane that rises 60 degrees with respect to the plane.
[0037]
In addition, when it is difficult to understand the details of the structure only with FIG. 3, the cross-sectional view shown in FIG. 4 may be referred to. That is, each figure [(a)-(d)] of Drawing 4 is a transverse cross section which cut the kit of the present invention in various places (circle cut). The reason why the cutting plane showing the left half sectional view is different from the right half is that the axis of the saw-toothed gear (12g) whose rotation is prohibited is the same as the axis of the push-up shaft (12s). The purpose is to show the surface.
[0038]
<< Overcap (C) >>
Again, in FIG. 3, (C) is an overcap. The upper body (11) of the kit (1) of the present invention is protected and functions to isolate the upper body (11) from contamination and the like. On the inner wall of the lower end area of the overcap (C), there is provided means for engaging with the engaging means of the outer wall of the upper end area of the lower main body (12) of the kit (1) of the present invention. The most common engagement means is a female screw. However, the engaging means is not limited to screws, and other means such as bayonet mount can be used. The following describes the case where the overcap (C) is removed.
[0039]
<< Mouthpiece (11m) >>
The mouthpiece (11m) is located at the uppermost end of the kit of the present invention, and is cylindrical, and its outer wall is usually narrowed upward. The significance of the tapered shape comes from the convenience of inserting the mouthpiece (11m) into the mouth of the inhaler. Its inner wall (11mi) Middle to barrier (11mb) Overhangs to the length of the approximate radius.
[0040]
Barrier (11mbThe function of) is measured inside the kit and the powder medicine waiting to be sprayed collapses before being used in the inverted state with the right side of the kit down, and the powder medicine does not float in the gas at the time of subsequent inhalation The purpose is to prevent a sudden discharge.
[0041]
The lower end region of the mouthpiece (11m) is fitted in the upper end region of the upper body (11) of the kit (1) of the present invention. The means for locking both members is not limited to the illustrated screwing.
<< Upper body (11) >>
The upper main body (11) is a cylinder, and the outer wall of the upper end region is usually tapered, and a gas introduction hole (11h) is provided on the lower right side wall. The function of the gas inlet hole (11h) is to provide an inlet for a transport gas for inhalation. In addition, the left side wall of the upper body (11) is illustrated as being cut out long in parallel to the generatrix, but the function thereof is within the inner cylinder (11i) incorporated in the kit (1) of the present invention. In addition, the number of uses of the kit (1) of the present invention or the remaining amount of the powder medicine accommodated in the inner cylinder (11i) can be seen through from the outside of the kit. The means for making it possible to detect the number of uses of the kit (1) of the present invention or the remaining amount of the stored powder medicine from the outside of the kit is not limited to the above illustrated example, and may be another means. Hereinafter, various members housed in the upper main body (11) will be described.
[0042]
<< Inclusive cylinder (11g) >>
The inclusion cylinder (11g) is a cylinder mounted on the inner side of the upper body (11), and has an enlarged diameter portion (11ge) at the upper end region, and a measuring plate holder (11b) at the upper edge of the enlarged diameter portion (11ge). ) And the enlarged diameter portion (11ge) is usually provided with four notches (11gc) from its upper edge. This notchKi (11gc) is fitted with a hook (11bc) of a measuring plate holder (11b) described later. Furthermore, several left-rotation prohibited ratchets (11ger). The left-rotation prohibition ratchet (11ger) engages with a left-rotation prohibition ratchet (11vr) provided on the periphery of the later-described measuring plate (11v) and prohibits the left rotation.
[0043]
The inclusion cylinder (11g) is provided with notches (11gc) at its lower end (in the example of the present invention, 4 pieces with a width of 45 degrees), thereby projecting from the outer wall of the enlarged diameter portion (12ne) of the push-up nut (12n) described later. It fits into a notch (12nfc) provided on the flange (12nf) and rotates as a unit.
[0044]
<< Measurement plate ratchet (11r), measurement plate holder (11b), measurement plate (11v) >> The measurement plate ratchet (11r) is a circular plate and usually has a plurality of counterclockwise non-rotating ratchets (11rb) on the outer periphery. And two or more through holes (11rh). The number and position of the through holes (11rh) coincide with the number and position of the measurement holes (11vh) provided in the measurement plate (11v) described later. The measuring plate ratchet (11r) is attached to the upper end of the large-diameter portion inside the upper body (11). The function of the weighing plate ratchet (11r) is to rotate it clockwise with the later-described weighing plate (11v) located coaxially therewith. For this purpose, a cylindrical projection (11rp) is provided at the center of the lower surface of the measuring plate ratchet (11r), and for example, a triangular recess (11rpc) is provided therein. The shape of the recess (11 rpc) may be a quadrangular shape, but it is preferable to avoid a pentagonal shape or more in order to inhibit the rotation of the rod-shaped body accommodated in the portion.
[0045]
The measurement plate holder (11b) is provided in contact with the lower surface of the measurement plate ratchet (11r), and is a disc having a left-rotation prohibited ratchet (11bb) at the periphery thereof, and in addition to the outer periphery from the upper surface periphery. It has a large diameter ridge (11bf) that protrudes upward and rises upward.
[0046]
Usually, a plurality of notches having a thickness of about ½ or less from the lower surface of the ridge (11bf) are usually provided, and four in the illustrated embodiment. Further, a small-diameter through hole (11bhs) is formed in the disc region, and a large-diameter circular through-hole (11bhb) is formed on the outer side on the same radius.
