Abstract
Description
(鼻腔投与容器100の構成)
図1~図6を参照して、本実施の形態における鼻腔投与容器100の構成について説明する。
薬液貯留部10は、バレル11およびフィンガークリップ部14から構成される。バレル11は、中空の略円筒状に形成される。バレル11の内部に、後述するプランジャー20およびガスケット28が差し込まれる。バレル11の一端は、薬液貯留部10の一端12を構成する。薬液貯留部10の一端12側に、ノズル12N(シリンジノズル)が形成される。薬液貯留部10の一端12側には、ノズル12Nを通してバレル11の内部に連通する噴霧ノズル12M(図1参照)が取り付けられる。図1に図示される噴霧ノズル12Mは、他の図面には図示されていないが、本実施の形態および以下の各実施の形態において、噴霧ノズル12Mはバレル11に取り付けられているものとする。バレル11と噴霧ノズル12Mとは、互いに一体的に構成されてもよく、本実施の形態のように別体として構成された後に互いに組み付けられてもよい。
図5は、鼻腔投与容器100の一部を分解した(プランジャー移動量規制部材40を本体部30から取り外した)状態を示す斜視図である。図5(および図4)に示すように、プランジャー20は、略棒状に形成される。プランジャー20は、薄板状に形成された4つのリブ部21を有する。
図5を再び参照して、プランジャー移動量規制部材40は、把持部41、ストッパ部42、およびストッパ部43を含む。ストッパ部42およびストッパ部43は、平板状に形成された把持部41の端部から連続するように形成される。ストッパ部42およびストッパ部43は、把持部41を挟んで対称に形成され、全体として略半割の円筒形状を呈している。
図4を再び参照して、鼻腔投与容器100が組み立てられる際には、まず、ガスケット28が、バレル11の開口部11Hを通して、バレル11の内部に差し込まれる。ガスケット28がバレル11の内部に差し込まれる前に、バレル11の一端12にゴムキャップなどが取り付けられ、この状態でバレル11の内部に薬液が充填されてもよい。
図7~図12を参照して、鼻腔投与容器100の動作について説明する。鼻腔投与容器100は、第1投与準備状態S11(図7参照)、第1投与開始状態S12(図8参照)、第1投与完了状態S13(図9参照)、第2投与準備状態S14(図10参照)、第2投与開始状態S15(図11参照)、および、第2投与完了状態S16(図12参照)の各状態に順次遷移する。
図7を参照して、鼻腔投与容器100は、組み立てられた状態で、ノズル12N側から薬液60が注入(または吸入)される(図7に示す状態)。薬液60の注入が完了することによって、鼻腔投与容器100は第1投与準備状態S11に遷移する。この際、薬液貯留部10(バレル11)の一端12側に、空気62が入り込む場合がある。
図8を参照して、鼻腔に投与されるべき薬液60の量を所定の値に規定することと、(必要に応じて)薬液貯留部10(バレル11)の内部に入り込んだ空気を抜くこととを目的として、プライミングという動作が実施される。
図9を参照して、鼻腔に投与されるべき薬液60の量が所定の値に規定された後、ノズル12N側に取り付けられた噴霧ノズル12M(図1参照)が一方の鼻腔の中に配置される。この状態で、押圧部23Pを利用して、プランジャー20は薬液貯留部10(バレル11)の内部に強く押し込まれる(矢印AR2参照)。
図10を参照して、第1回目の薬液60の投与が完了した状態(図9に示す状態)においては、プランジャー移動量規制部材40の挟持部42E,43Eは、プランジャー20の括れ部26に対向するように位置している。挟持部42E,43Eおよび括れ部26の配置関係によって、プランジャー移動量規制部材40のプランジャー20(リブ部21)に対する係合状態は解除されている。
図11を参照して、プランジャー移動量規制部材40が本体部30から取り外された後(第2投与準備状態S14の後)、鼻腔投与容器100のノズル12N側に取り付けられた噴霧ノズル12M(図1参照)は、他方の鼻腔の中に配置される。これにより、鼻腔投与容器100は第2投与開始状態S15に遷移する。
図12を参照して、鼻腔投与容器100の噴霧ノズル12M(図1参照)が他方の鼻腔の中に配置された後、押圧部23Pを利用して、プランジャー20が薬液貯留部10(バレル11)の内部にさらに押し込まれる(矢印AR4参照)。プランジャー20は薬液貯留部10の内部を前進する。ガスケット28は、プランジャー20に押されることによって薬液貯留部10の内部にさらに入り込む。
鼻腔投与容器100においては、上述のとおり、当接部25がプランジャー20に設けられるとともに、プランジャー移動量規制部材40が本体部30のプランジャー20に取り付けられる。プランジャー20の当接部25がプランジャー移動量規制部材40のストッパ部42,43に当接することによって、鼻腔投与容器100は、第1投与準備状態S11(図7参照)から第1投与開始状態S12(図8参照)に容易に遷移することができる。なお、上述のとおり、当接部25は必要に応じて設けられるとよい。
第2回目の薬液60の投与が開始される際(第2投与開始状態S15(図11参照))において、プランジャー20の当接部25は、垂下部15の内周面に対して摩擦係合するように構成されてもよい。当該構成は、当接部25の突出寸法を垂下部15の内径に対して若干大きくすることによって得られる。
図13~図15を参照して、本実施の形態における鼻腔投与容器101について説明する。鼻腔投与容器101と上述の実施の形態1における鼻腔投与容器100(図1参照)とは、以下の点において相違する。
図16~図18を参照して、本実施の形態における鼻腔投与容器102について説明する。鼻腔投与容器102と上述の実施の形態1における鼻腔投与容器100(図1参照)とは、以下の点において相違する。
図19~図21を参照して、本実施の形態における鼻腔投与容器103について説明する。鼻腔投与容器103と上述の実施の形態1における鼻腔投与容器100(図1参照)とは、以下の点において相違する。
(鼻腔投与容器104の構成)
図22~図27を参照して、本実施の形態における鼻腔投与容器104の構成について説明する。図22は、鼻腔投与容器104を示す第1斜視図である。図23は、鼻腔投与容器104を示す第2斜視図である。
薬液貯留部10は、バレル11およびフィンガークリップ部14Dから構成される。バレル11は、中空の略円筒状に形成される。バレル11の内部に、後述するプランジャー20およびガスケット28が差し込まれる。バレル11の一端は、薬液貯留部10の一端12を構成する。薬液貯留部10の一端12側に、ノズル12Nが形成される。上述の実施の形態1と同様に、薬液貯留部10の一端12側には、ノズル12Nを通してバレル11の内部に連通する噴霧ノズル12M(図1参照)が取り付けられる。バレル11と噴霧ノズル12Mとは、互いに一体的に構成されてもよく、本実施の形態のように別体として構成された後に互いに組み付けられてもよい。
図24を再び参照して、本実施の形態におけるプランジャー20は、略棒状に形成される。プランジャー20は、薄板状に形成された4つのリブ部21を有する。4つのリブ部21は、プランジャー20の長手方向に沿って、プランジャー20の一端22から他端23に向かって延在する。4つのリブ部21は、90°間隔で配置されるとともに、プランジャー20の長手方向に対して直交するように外側に向かって起立する。
図24および図25を再び参照して、プランジャー移動量規制部材40Dは、把持部41、ストッパ部42、ストッパ部43、およびフック部46J(図25参照)を含む。ストッパ部42およびストッパ部43は、把持部41の端部から連続するように形成される。ストッパ部42およびストッパ部43は、把持部41を挟んで対称に形成され、全体として略半割の円筒形状を呈している。
図27は、鼻腔投与容器104が組み立てられる際の様子を示す断面図である。鼻腔投与容器104が組み立てられる際には、まず、バレル11のフランジ部11Rに対して、フィンガークリップ部14Dが取り付けられる(矢印AR14D参照)。上述のとおり、フィンガークリップ部14Dは、フランジ部11Rを挟み込みつつ、フランジ部11Rに対して摩擦係合によって取り付けられる。これにより、薬液貯留部10(図22および図23参照)が得られる。また、上述のとおり、バレル11の一端12には、噴霧ノズル12M(図1参照)が取り付けられる。
図28~図33を参照して、鼻腔投与容器104の動作について説明する。鼻腔投与容器104は、第1投与準備状態S21(図28参照)、第1投与開始状態S22(図29参照)、第1投与完了状態S23(図30参照)、第2投与準備状態S24(図31参照)、第2投与開始状態S25(図32参照)、および、第2投与完了状態S26(図33参照)の各状態に順次遷移する。
図28を参照して、鼻腔投与容器104は、組み立てられた状態で、ノズル12N側から薬液60が注入(または吸入)される(図28に示す状態)。薬液60の注入が完了することによって、鼻腔投与容器104は第1投与準備状態S21に遷移する。この際、薬液貯留部10(バレル11)の一端12側に、空気62が入り込む場合がある。
図29を参照して、鼻腔に投与されるべき薬液60の量を所定の値に規定することと、(必要に応じて)薬液貯留部10(バレル11)の内部に入り込んだ空気を抜くこととを目的として、プライミングという動作が実施される。
図30を参照して、鼻腔に投与されるべき薬液60の量が所定の値に規定された後、ノズル12N側に取り付けられた噴霧ノズル12M(図1参照)が一方の鼻腔の中に配置される。この状態で、押圧部23Pを利用して、プランジャー20が薬液貯留部10(バレル11)の内部に強く押し込まれる(矢印AR2参照)。
図31を参照して、第2回目の薬液60の投与を行なうために、矢印AR3に示すように、プランジャー移動量規制部材40Dは本体部30から取り外される(図31に示す状態)。プランジャー移動量規制部材40Dが本体部30から取り外されることによって、鼻腔投与容器104は第2投与準備状態S24に遷移する。
図32を参照して、プランジャー移動量規制部材40Dが本体部30から取り外された後(第2投与準備状態S24の後)、鼻腔投与容器104のノズル12N側に取り付けられた噴霧ノズル12M(図1参照)は、他方の鼻腔の中に配置される。これにより、鼻腔投与容器104は第2投与開始状態S25に遷移する。
図33を参照して、鼻腔投与容器104の噴霧ノズル12M(図1参照)が他方の鼻腔の中に配置された後、押圧部23Pを利用して、プランジャー20が薬液貯留部10(バレル11)の内部にさらに押し込まれる(矢印AR4参照)。
鼻腔投与容器104においては、上述のとおり、当接部25Dがプランジャー20に設けられるとともに、本体部30(フィンガークリップ部14D)には突出部15Tが設けられる。プランジャー20の当接部25Dがフィンガークリップ部14Dの突出部15Tに当接することによって、鼻腔投与容器104は、第1投与準備状態S21(図28参照)から第1投与開始状態S22(図29参照)に容易に遷移することができる。なお、上述のとおり、当接部25Dは必要に応じて設けられるとよい。
