Abstract
Description
また、検査技術についても、装置技術の発展により、検査項目に応じた自動検査装置が開発されている。例えば、便潜血検査においては、糞便採取保存容器をそのまま検査装置にセットした後、自動で検査及び/又は測定することが可能となっている。
しかし、実公平05-017652号に記載の便潜血検査容器では、遠心分離機などの汎用の理化学装置や核酸抽出装置に直接装着することができなかった。
このため、採取した糞便を実公平05-017652号に記載の便潜血容器に収容して保存した場合において、採取した糞便から核酸を抽出するには、核酸抽出装置に装着することが可能な汎用性の高い容器への糞便の移し替え等の作業が必要となる。しかし、糞便を他の容器へ移し替えをすると、コンタミネーションが生じやすく、また、移し替えの際に不定量の糞便が元の容器や移し替えを行う器具に付着するなどすることによって、核酸抽出装置へ装着する容器へ取り出す検体サンプルの量を所定の許容範囲内に定量化することが困難となり、さらには、検体サンプルを取り違える等の問題が生じやすかった。
また、本発明は、大きな力を加えなくても糞便等の検体の中に挿入させ易く、検査に十分な量の検体を定量化して採取可能で、且つ、遠心分離機などの汎用の理化学装置を用いて核酸等を抽出すること等が必要な検査においても、採取し保存した検体を他の容器に移し替えることなく、そのまま汎用の理化学装置に装着でき、しかも所定の許容範囲内に定量化された十分な採取量の検体を検査に用いることが可能な検体用容器を提供することを第2の目的としている。
なお、本発明において、把持部とは、蓋部材を回転させやすくするために把持できるように形成した部位である。把持部は、例えば、蓋部材の少なくとも一部を略平面を有する矩形状、多角形状、Dカット形状や、蓋部材の少なくとも一部を凸部や凹部を有する形状などに形成して構成するのが好ましい。
また、本発明によれば、大きな力を加えなくても糞便等の検体の中に挿入させ易く、検査に十分な量の検体を定量化して採取可能で、且つ、遠心分離機などの汎用の理化学装置を用いて核酸等を抽出すること等が必要な検査においても、採取し保存した検体を他の容器に移し替えることなく、そのまま汎用の理化学装置に装着でき、しかも所定の許容範囲内に定量化された十分な採取量の検体を検査に用いることが可能な検体採取容器が得られる。
本発明の検体用容器は、その一端が開口され、検体を分散又は保存させる液体を収容し得ると共に、汎用の理化学装置に装着可能な筒状に形成された容器本体と、検体を採取するための検体採取棒と、検体採取棒の後端部と接続する蓋部材と、容器本体と蓋部材とを連結する中継ユニットとからなり、中継ユニットは、両端が開口され、その一端で容器本体の開口端に着脱可能であるとともに、その他端で蓋部材を着脱可能な筒状に形成された連結部を備えている。
そして、本発明の検体用容器によれば、ヒト由来の検体として、例えば、糞便を採取する場合、採取量が0.1~2gの範囲となるように構成したときに、誤差の範囲を±10%に定量化して採取することが可能となる。なお、採取量が0.1~0.5gの範囲となるように構成するのが、より好ましい。
また、本発明の検体用容器においては、粘性の高い他のヒト由来の検体についても、検体採取量が0.1~2gの範囲となるように構成するのが好ましい。
または、貫通壁の貫通孔の近傍に弾性部材を備えてもよい。その場合は、例えば、貫通壁の貫通孔を構成する面に環状の溝部を形成し、その環状の溝部に、その内径が該貫通孔の径よりも小さい環状の弾性部材を嵌入した構成とするのがよい。また、例えば、貫通壁が、貫通孔の中心を通る放射状の切り込みを有して貫通孔を覆い、検体採取棒が貫通孔に挿し込まれた状態のときに変形して検体採取棒に密着する弾性部材を備えるようにしてもよい。
なお、貫通壁の貫通孔を構成する面に複数備えられた環状の溝部の断面形状は、環状の溝部に挟まれる部分を薄肉化させて貫通方向に変形しやすくできれば、コの字状、Vの字状、円弧状のいずれに形成してもよい。
また、凹状の採取部と凸状の取出部とを嵌合状態から分離できるようにすると、検体採取棒を用いた検体採取の際や、検体を容器本体に取り出した後、容器本体を汎用の理化学装置に装着する際に、検体採取部を容器本体から取り外すことができる。
検体採取棒における凹状の採取部から検体採取棒の外周面に繋がる通路は、例えば、凹状の採取部の側面から検体採取棒の外周面に繋がる複数のスリットで構成するのが好ましい。また、例えば、凹状の採取部の底面から検体採取棒の外周面に繋がる複数の押出孔で構成してもよい。
検体がゲル状の柔らかい物体である場合には、上述のような凹状の採取部を介して採取しようとしても採取部の奥まで検体を充填させることが難しく、しかも、採取した検体が凹状の採取部の開口から流れ出し易い。これに対し、検体採取棒の採取部を、検体採取棒の先端部の外周面に設けた格子状の溝で構成すれば、ゲル状の検体に対しては付着させ易く定量的に採取しやすい。
しかも、二股部が閉じ状態のときに所定量の検体を収納するようにするとともに、貫通孔が、二股部が閉じられた状態の検体採取棒を摺接しながら貫通させるようにすれば、検体を定量化して採取し、容器本体内で保存できる。
このようにすれば、検体収容部を介して、検体を容器本体の液体に分散させ易い大きさに細片化できる。また、検体排出口を介して余分な検体を排出できるので、二股部が閉じられた状態の検体採取棒を貫通孔に挿入することにより、検体を定量化して採取し、容器本体内で保存できる。
しかも、容器本体内で二股部を開いた状態にしたときには、溝部における二股部の開閉方向に沿う開口面が遮蔽部で覆われず、溝部に採取した糞便等の検体が容器本体内の液体と接触する面積を大きくとることができる。このため、検体採取棒で採取した検体を容器本体の液体に一層分散させ易くなる。
このようにすれば、上述した検体収容部を備えた構成と、上述した溝部と遮蔽部を備えた構成とを併せ持つことになり、夫々同様の効果が得られる。
このようにすれば、薄板状の板面部を検体収容部に入れることで、検体収容部に収容されることによって細片化された検体をより一層細片化することができ、検体採取棒で採取した検体を容器本体の液体により一層分散させ易くなる。
このようにすれば、二股部を閉じる際に、溝部における二股部の閉じ側の開口部から溝部における二股部の開き側の開口部へ向けて、検体を溝部の中へ導入させ易くなる。また、薄板状の板面部を検体収容部に入れる構成においては、検体収容部に収容されることによって細片化された検体をより一層細片化させ易くなり、検体採取棒で採取した検体を容器本体の液体にさらにより一層分散させ易くなる。
このようにすれば、二股部の開閉操作が容易になる。
また、本発明の検体用容器においては、検体採取棒は、二股部が開き状態となる所定位置に環状部材を固定する環状部材固定手段を有するのが好ましい。
このようにすれば、検体採取時においては、中継ユニットを容器本体に装着したままの状態を保ちながら、検体採取棒と接続した蓋部材を中継ユニットから取り外しやすくなる。また、検体採取後、検体採取棒を中継ユニットの貫通壁を貫通させて容器本体の内部に入れるときには、中継ユニットの変形を極力抑えることができる。また、蓋部材を中継ユニットに取り付けるときにも中継ユニットの変形を抑えることができる。更に、容器本体から中継ユニットを取り外し易くなる。
本発明において、把持部とは、蓋部材を回転させやすくするために把持できるように形成した部位である。把持部は、例えば、蓋部材の少なくとも一部を略平面を有する矩形状、多角形状、Dカット形状や、蓋部材の少なくとも一部を凸部や凹部を有する形状などに形成して構成するのが好ましい。このようにすれば、蓋部材と中継ユニットとが螺子を介して着脱可能な構成の場合には、把持部を介して蓋部材を回転させやすくなるので、蓋部材を中継ユニットに着脱させやすくなる。

図1は本発明の第一実施形態にかかる検体用容器の概略構成を示し、図2は図1に示した検体用容器の要部の一構成例を示している。図2では、便宜上、中継ユニットの連結部と容器本体以外の構成は図示を省略してある。
容器本体1は、その一端が開口され、検体を分散又は保存させる液体5を収容しうるとともに、汎用の核酸抽出装置などの汎用の理化学装置に装着可能な大きさ及び形状の筒状に形成されている。容器本体1の開口端の外周部1aには、螺子1a1が形成されている。また、容器本体1の底部には、凸状の取出部6が固定された状態で設けられている。検体採取棒2は、その先端部に凹状の採取部2aを有している。凹状の採取部2aは、容器本体1の底部に設けられた凸状の取出部6と嵌合及び離脱可能に形成されている。蓋部材3は、検体採取棒2の後端部2bと接続している。また、蓋部材3の内周部3aには、螺子3a1が形成されている。
まず、初期状態においては、図1(a)に示すように、中継ユニット4は容器本体1に取り付けられるとともに、蓋部材3は中継ユニット4に取り付けられている。また、検体採取棒2は、中継ユニット4の貫通壁4bの貫通孔4b1を貫通するとともに、凹状の採取部2aが凸状の取出部6と嵌合している。
次いで、中継ユニット4の連結部4aの他端から外れた検体採取棒2を用い、その先端部に設けられた凹状の採取部2aに検体(図示省略)が入るようにして、検体を採取する。
次いで、蓋部材3の内周部3aに形成された螺子3a1を中継ユニット4における連結部4aの他端部4a2の外周に形成された螺子4a21に螺合させ、閉じ方向に回転させる。すると、貫通孔4b1を貫通した検体採取棒2の凹状の採取部2aが容器本体1の底部に設けられた凸状の取出部6に嵌合し、採取部2aに採取された検体が取出部6を介して容器本体1に押し出されるとともに、蓋部材3が中継ユニット4に締着される。これにより、採取した検体が容器本体1に密閉状態に保管される。
図3は本発明の第二実施形態にかかる検体容器の要部の一構成例を、図4及び図5は互いに異なるその変形例を、それぞれ示した説明図である。なお、これらの図では、便宜上、中継ユニットの連結部と容器本体以外の構成は図示を省略してある。
例えば、図3に示す例の検体用容器では、図3(b)、図3(c)に示すように、中継ユニット4における連結部4aの一端の外周部4a1’に、貫通方向に沿って形成された環状の凸部4a11’と、容器本体1の開口端の内周部1a’よりも大きな径を持つ環状のストッパ部4a12’と、ストッパ部4a12’の容器本体1側に設けられたOリング4a13’を有している。また、容器本体1の開口端の内周部1a’には、図3(a)、図3(c)に示すように、環状の凸部4a11’と嵌合可能な環状の凹部1a1’が設けられている。
また、容器本体1の開口端の外周部1aには、図4(a)、図4(c)に示すように、中継ユニット4の連結部4aに設けられた窓部4a13”に挿入可能な複数の爪部1a2が設けられている。爪部1a2は、窓部4a13”に挿入した状態で上下方向に所定量の力を加えたときにその根元から折れるように形成されている。
一方、図3(e)に示す状態から容器本体1から中継ユニット4を分離するときには、中継ユニット4を容器本体1に対して引く。すると、環状の凸部4a11’が環状の凹部1a1’との嵌合を解除されて、環状の凸部4a11’が容器本体1の開口端の内周部1a’に摺接しながら、容器本体1の開口端の方向に進む。そして、所定位置まで進んだときに、図3(c)に示すように、中継ユニット4は容器本体1から外れる。
一方、図4(e)に示す状態から容器本体1から中継ユニット4を分離するときには、図4(f)に示すように、窓部4a13”に挿入した状態の爪部1a2の先端に対し、上下方向に所定量の力を加える。すると、爪部1a2は根元から折れる。そこで、折れた爪部1a2を取り除くことによって、中継ユニット4は容器本体1から分離可能な状態になる。次いで、中継ユニット4を容器本体1に対して引くことにより、中継ユニット4は容器本体1から外れる。
一方、容器本体1から中継ユニット4を分離するときには、中継ユニット4を容器本体1に対して引く。すると、中継ユニット4は、窓部4a13”の下辺が爪部1a2の下側面1a21に当接しながら徐々に外側に押し広げられていく。そして、中継ユニット4を所定位置まで引いたときに、窓部4a13”の下辺が爪部1a2の下側面1a21を外れ、容器本体1から分離可能な状態になる。そこで、中継ユニット4を容器本体1に対してさらに引くことにより、中継ユニット4は容器本体1から外れる。
その他の作用効果は、第一実施形態の検体用容器と略同じである。
図6は本発明の第三実施形態にかかる検体用容器の要部構成を示す図である。第三実施形態の検体用容器は、中継ユニット4の貫通壁4bは、その一部に弾性部材を備えた構成となっている。詳しくは、図6に示すように、貫通壁4bの貫通孔4b1を構成する面に、環状の溝部4b11が形成され、環状の溝部4b11に、その内径が貫通孔4b1の径よりも小さい環状の弾性部材4b12が嵌入されている。環状の弾性部材4b12は、貫通孔4b1に検体採取棒2を貫通させたときに、検体採取棒2に押されて弾性変形し、検体採取棒2に密着するようになっている。その他の構成は第一実施形態の検体用容器と略同じである。
図7は本発明の第四実施形態にかかる検体用容器の要部の構成を示す図である。第四実施形態の検体用容器は、貫通壁4bは、貫通孔4b1の中心を通る放射状の切り込み4b21を有して貫通孔4b1を覆う弾性部材4b2を備えている。弾性部材4b2は、検体採取棒2が貫通孔4bに挿し込まれた状態のときに変形して検体採取棒2に密着するように構成されている。その他の構成は、第一実施形態の検体用容器と略同じである。
図8は本発明の第五実施形態にかかる検体用容器の構成を示し、図9はその検体用容器における貫通壁に設ける溝部の断面形状の形成例を示す説明図である。
なお、貫通壁4bの貫通孔4b1を構成する面に形成される複数の環状の溝部の断面形状は、図8及び図9(a)に示すようなコの字状の溝部4b11’の他に、図9(b)に示すようなVの字状、の溝部4b11”、図9(c)に示すような円弧状の溝部4b11”’のいずれの形状に形成しても、同様の作用効果を得ることができる。
図10は本発明の第六実施形態にかかる検体用容器の構成を示す図である。第六実施形態の検体用容器は、中継ユニット4が連結手段7を介して凸状の取出部6と連結し、中継ユニット4を容器本体1から取り外すと同時に、第一実施形態の検体用容器において説明した凸状の取出部6も、検体採取棒2の凹状の採取部2aを嵌合した状態のまま容器本体1から分離することができるように構成されている。
連結手段7は、図10(a)に示すように、係着部材7aと、骨組み状部材7bとで構成されている。係着部材7aは、中継ユニット4の連結部4aの内側に固定されている。骨組み状部材7bは、図10(b)に示すように、容器本体1の内側に収容可能な筒状に形成されている。また、骨組み状部材7bは、底部7b1に三叉部7b11を備えている。そして、骨組み状部材7bは、底部7b1における三叉部7b11の中央部で凸状の取出部6の下端6aを固定している。また、骨組み状部材7は、その上部7b2が、係着部材7aに係着され得るように形成されている。その他の構成は、第一実施形態の検体用容器と略同じである。
図11は本発明の第七実施形態にかかる検体用容器の一例における要部の部分説明図、図12は他の例における要部の部分説明図である。
その他の作用効果は、第一実施形態の検体用容器と略同じである。
図13は本発明の第八実施形態にかかる検体用容器の一例における要部の部分説明図、図14は他の例における要部の部分説明図である。
第八実施形態の検体用容器は、検体採取棒2の採取部の構成が第一実施形態乃至第七実施形態の検体用容器とは異なる。詳しくは、図13の例では、検体採取棒2は、先端部の外周面に格子状に形成された溝2a1’からなる採取部2a’を有している。また、図14の例では、検体採取棒2は、先端部にブラシ状の採取部2a”を有している。
そして、検体採取棒2の採取部2a’又は2a”で採取した検体を、容器本体1の液体5に分散または混濁させることによって取り出すことを前提として構成されており、容器本体1の底部には凸状の取出部は設けられていない。その他の構成は、第一実施形態の検体用容器と略同じである。
図15は本発明の第九実施形態にかかる検体用容器における要部の部分説明図である。
第九実施形態の検体用容器は、検体採取棒の構成が、第一実施形態乃至第八実施形態の検体用容器における検体採取棒とは異なり、その内部に採取した検体を外部に押し出す機構を備えている。詳しくは、検体採取棒2は、吸着部2a”’と、筒部材2b”’と、棒状部材2c”’とで構成されている。吸着部2a”’は、スポンジ状部材で構成されている。筒部材2b”’は、両端が開口しており、先端で吸着部2a”’と接続している。棒状部材2c”’は、筒部材2b”’の内部を移動可能な大きさの径に形成され、その先端部2c1”’で吸着部2a”’を押圧可能に構成されている。また、棒状部材2c”’の他端は、蓋部材3に接続されている。その他の構成は、第一実施形態の検体用容器と略同じである。
図16は本発明の第十実施形態にかかる検体用容器の概略構成を示す説明図、図17はその検体用容器の蓋部材の構成を示す説明図である。
なお、中継ユニット4の連結部4aと、蓋部材3とを、異なる材質で構成すれば、容器の密閉性を保つ作用を持たせることができるとともに、蓋部材3を中継ユニット4に着脱しやすくなる。また、容器本体1と、中継ユニット4の連結部4aとを、異なる材質で構成すれば、容器の密閉性を保つ作用を持たせることができるとともに、中継ユニット4を容器本体1に着脱しやすくなる。
図18は本発明の第十一実施形態にかかる検体用容器の構成を示す説明図、図19はその検体用容器における蓋部材及び検体採取棒の構成を示す説明図、図20は蓋部材及び検体採取棒を側方からみた図、図21は中継ユニットの構成を示す図、図22は容器本体の構成を示す図である。
なお、検体収容部2c1は、二股部2cにおいて分岐する一方の部位に、少なくとも一つ設けた構成でもよい。
また、検体排出口2c12は、採取する検体の種類に応じて、検体導入口2c11と同形状、或いは異なる形状及び/又は寸法に形成してもよい。
また、貫通孔4b1は、二股部2cが閉じられた状態の検体採取棒2を摺接しながら貫通させることができる大きさに形成されている。
検体採取棒2は、環状部材7を後端へ向けて所定量移動させると、二股部2cが環状部材7による二股部2cの開き方向への規制を解除され、その弾性により先端から外側に開く。検体採取前の段階の初期状態においては、図18(a)に示すように、中継ユニット4は容器本体1に取り付けられるとともに、蓋部材3は中継ユニット4に取り付けられている。また、検体採取棒2は、中継ユニット4の貫通壁4bの貫通孔4b1を貫通しており、検体用容器は密封されている。環状部材7は、貫通壁4bにおける上側の面を介して検体採取棒2の後端部2b側の所定位置に設けられた突起2dと当接する位置まで押し上げられ、環状部材7の内周面の一部が突起2dと当接することにより位置を固定される。このとき二股部2cは、開いた状態となっている。
貫通孔4b1に挿入した検体採取棒2を、環状部材7が貫通壁4bの上側の面に当接するまで押し込んだ後、さらに検体採取棒2の挿入を続けると、環状部材7は貫通壁4bにおける上側の面を介して押し上げられる。これにより、二股部2cは、弾性により容器本体1内の保存液中で開いて行く。検体収容部2c1に採取された検体は、容器本体1内の保存液中に拡散される。
また、保存液中においては、検体が拡散されやすくする必要がある。しかるに、第十一実施形態の検体採取容器では、検体収容部2c1を複数設けることで、検体を細片化して採取することが可能となる。そして、細片化された検体は、保存液中での拡散が容易となる。
図23は本発明の第十二実施形態にかかる検体用容器の構成を示す説明図、図24及び25はその検体用容器における蓋部材及び検体採取棒の構成を示す説明図、図26は図24(b)に示した蓋部材及び検体採取棒を下方からみた図である。図27は検体用容器の蓋部材及び検体採取棒における環状部材固定手段の一変形例を示す説明図である。なお、図中、第十一実施形態の検体採取容器と同じ構成部材には同じ符号を付し、詳細な説明は省略する。

先ず、蓋部材3に固定された雄螺子3cに、後端部2bのフランジ2b1が先になるようにして胴体部2bcを通す。次いで、胴体部2bcが雄螺子3cを中心に回動自在となるように、フランジ2b1を囲うようにして、環状の保持部3bを蓋部材3に固定する。次いで、雌螺子3dを雄螺子3cに螺合させる。次いで、一対の二股部2cの夫々における根元側端面から、断面がT字状の溝部2e1に、雌螺子3dのT字部3d1を嵌める。次いで、二股部2cの根元を胴体部2bcの内部に差し込み、夫々の二股部2cに設けられた軸2gを、胴体部2bcの下部に設けられた開閉支持部2fの軸穴に通し、二股部2cを胴体部2bcに対して開閉可能に連結する。これにより、検体採取棒2は蓋部材3に対して回動自在に組み付けられ、胴体部2bcを把持しながら蓋部材3を回動させることで、二股部2cを開閉させることが可能になる。
図36は本発明の第十五実施形態にかかる検体用容器の構成を示す説明図、図37は蓋部材及び検体採取棒の構成を示す説明図、図38は蓋部材及び検体採取棒の断面図、図39は図38の断面図における二股部の連結部位の拡大図である。図40は蓋部材及び検体採取棒を下方からみた図である。なお、第十一~第十三実施形態の検体用容器と同じ構成部材は同じ符号を付し詳細な説明は省略する。
雌螺子2-32は、雄螺子2-31の螺子部2-312と螺合した状態において、頭部付きピン状連結部材2-3の頭部を構成する。
なお、溝3fは、図40に示すように、蓋部材3を裏からみて反時計回り(左回り)に中心に向かうように、渦の向きが設定されており、蓋部材3における二股部2-1a,2-2aを閉じ合わせる回転方向が、蓋部材3が図36に示した中継ユニット4の連結部4aの他端の外周部4a2(の螺子4a21)から外れるときの回転方向に一致するようになっている。その他の構成は、第十一~第十三実施形態の検体採取容器と略同じである。

図44は本発明の第十七実施形態にかかる検体用容器における蓋部材及び検体採取棒の概略構成を示す説明図である。なお、第十一~第十三実施形態の検体用容器と同じ構成部材は同じ符号を付し詳細な説明は省略する。

そして、凹状の採取部2aと凸状の取出部4cは、互いに嵌合可能、且つ、嵌合状態から分離可能に形成され、凹状の採取部2aに凸状の取出部4cが挿入するにしたがって検体をスリット2a1を通して外部に押し出すように構成されている。

図51は本発明の第二十実施形態にかかる検体用容器における蓋部材及び検体採取棒の構成を示す説明図、図52は検体用容器の構成を示す説明図である。なお、第十一実施形態の検体用容器と基本的な構成が同じ部材は同じ符号を付し詳細な説明は省略する。
図53は本発明の第二十一実施形態にかかる検体用容器における蓋部材及び検体採取棒の構成を示す説明図である。なお、第二十実施形態の検体採取容器における検体採取棒と同じ構成部材には同じ符号を付し、詳細な説明は省略する。
例えば、上記実施形態における中継ユニット4の連結部4a、蓋部材3、容器本体1を弾性部材で構成し、中継ユニット4の連結部4aは、貫通壁4b及び蓋部材3よりも弾性率が小さく、容器本体1よりも弾性率が大きく、蓋部材3は、貫通壁4bよりも弾性率が小さい弾性部材で構成するとよい。そのように構成すれば、蓋部材3が中継ユニット4よりも柔らかいので、変形しやすく、脱着しやすい。また、中継ユニット4は容器本体1よりも柔らかいので、変形しやすく、脱着しやすい。
このため、蓋部材3の回転方向を切換えるだけで、検体を採取するときには、中継ユニット4と容器本体1とが装着したままの状態を保ちながら蓋部材3を中継ユニット4から取り外すことができ、一方、採取した検体を容器本体1内に取り出した後、汎用の検査装置で検査をするときには、蓋部材3を中継ユニット4に装着したままの状態を保ちながら中継ユニット4を容器本体1から取り外すことができる。
このため、蓋部材3の回転方向を切換えるだけで、検体を採取するときには、中継ユニット4と容器本体1とが装着したままの状態を保ちながら蓋部材3を中継ユニット4から取り外すことができる。一方、採取した検体を容器本体1に取り出した後、汎用の検査装置で検査をするときには、蓋部材3を中継ユニット4に装着したままの状態を保ちながら中継ユニット4を容器本体1から取り外すことができる。
