Abstract
Description
いくつかの実施形態では、支持体は、長手方向に延びる筒を有していてもよい。いくつかの実施形態では、支持体は、長手方向に延びる筒状に形成されていてもよい。
いくつかの実施形態では、支持体の、長手方向から見た断面形状は、円形又は楕円形であってもよい。いくつかの実施形態では、支持体は、例えば三角形、四角形、五角形、六角形、八角形などの多角形の断面形状を有していてもよい。
いくつかの実施形態では、圧縮部材は、吸収体に対向して配置され、吸収体を押圧する押圧板を有していてもよい。いくつかの実施形態では、圧縮部材は、押圧板に交差する方向に沿って延びる筒状の外側壁を有していてもよい。いくつかの実施形態では、支持体は、吸収体を押圧板側に向けた状態で外側壁の内側に挿入可能に構成されていてもよい。
いくつかの実施形態では、ストッパは、外側壁の内側に挿入される吸収体に向かって突出する突起を有していてもよい。
いくつかの態様では、吸収体の体積の変化(例えば膨張)量を用いて、液体の吸収の状態を判断してもよい。吸収体の管軸方向の膨張量(長さ)に基づいて、採取量を測定し、又は吸収ステップの完了を判断してもよい。吸収体の膨張量の測定は、支持体に目盛りを設けてもよい。例えば、吸収体が支持体の内部に膨張する場合に、支持体の目盛りを用いて膨張量を測定してもよい。例えば、通常の外側壁に目盛りを設けてもよい。吸収体が支持体の外側に膨張する場合に、筒状の外側壁に設けられた目盛りを用いて、吸収体の膨張量を測定することができる。例えば、別部材のスケールを用意し、当該スケールをあてがって、吸収体の膨張量を測定してもよい。
いくつかの態様では、吸収体の変色により、液体の吸収量を判断してもよい。例えば、吸収体は、水と接触して変色する物質を含んでいてもよい。変色した吸収体の部分のサイズ(例えば管軸方向の長さ)に基づいて、液体の吸収量を判断してもよい。その膨張の長さは、例えば支持体に設けた目盛りを用いて測定してもよい。例えば、吸収体全体又は吸収体のある部位全体が変色したことにより、十分な量の液体を採取したと判断してもよい。
いくつかの態様では、複数の連結された吸収体が提供され、その内で、特性が変化した吸収体の数に基づいて、液体の吸収量を判断してもよい。例えば、先端(対象に接触又は近接する端部)から一つ目二つ目の吸収体で特性(膨張、変色など)が変化し終え、三つ目の吸収体での特性が変化し始めたことで、十分な量の液体を採取したと判断してもよい。
いくつかの態様では、タンクに目盛りを設けてもよい。タンクに回収された液体の量を目盛りを用いて測定し、又はそれにより十分の液体が採取できたかを判断してもよい。
支持体120は、長手方向Daに延びる筒121と、ストッパ(固定部)123と、を備えている。筒121は、長手方向Daから見た断面形状が、例えば、円形、楕円形、多角形等のうちの一つに形成されている。
いくつかの実施形態では、ストッパ123は、後述する吸収体130に向かって突出する突起又は三次元構造を有していてもよい。この突起により、例えば吸収体130をより圧縮変形させて吸収体130から液体を、より効率良く排出させることができる。
吸収体130は、弾性材を含んでいる。吸収体130は、その全体が弾性材によって形成されていてもよい。吸収体130は、その一部が弾性材によって形成されていてもよい。吸収体130は、液体の収集対象に接触したときに弾性変形しうるように構成されている。このような吸収体130を形成する弾性材として、弾性を有し、かつ多孔質である材料を用いてもよい。このような弾性材としては、例えばセルロースが挙げられる。吸収体130を形成する弾性材は、セルロース以外(非セルロース材料)であってもよい。
液体500を吸収体130に吸収させる工程S11では、収集器本体110の吸収体130を液体500(図3などに図示、以下略)に接触させる。いくつかの実施形態では、液体収集器100で、液体500として体液を収集する場合、吸収体130を、対象者の体液が分泌される場所に直接押し当てる、又は接触させる。吸収体130を直接押し当てる、対象者の体液が分泌される場所は、例えば非限定的に、眼球、眼の周縁部の目尻又は目頭、口腔内(例えば舌下)、鼻腔内、皮膚表面である。いくつかの実施形態では、対象者から分泌される体液は、容器内に収容されてもよい。その場合、吸収体130は、容器内に収容された体液に接触して、液体500を吸収してもよい。いくつかの実施形態では、支持体120を、吸収体130が設けられている側を上方に向けて配置してもよい。体液を上方から吸収体130に滴下してもよい。
図7に示す液体収集器200は、収集器本体210と、第二シリンダとしての圧縮部材250と、を備える。
押圧体253は、支持体220が長手方向Daの一端側に押し込まれた場合に、吸収体230を押圧する。
押圧体253は、長手方向Daの両側、つまり吸収体230が配置される側と反対側とを連通する連通孔257を有している。
タンク240は、吸収体230が圧縮されることで吸収体230から排出される液体500を収容する。タンク240は、圧縮部材250の外側壁251の内側に形成されている。タンク240は、押圧体253に対して、吸収体230が配置される側の反対側に配置されるように構成されている。タンク240は、外側壁251内で、底板252と押圧体253との間に、液体収容空間241を画成している。液体収容空間241は、内部に液体500を収容可能に構成されている。
液体500を吸収体230に吸収させる工程S21では、収集器本体210の吸収体230を液体500に接触させる。図8に示すように、吸収体230は、液体500を吸収すると膨張する。
液体500をタンク240に収容する工程S23では、吸収体230から排出された液体500が、押圧体253に形成された連通孔257を通して、タンク240の液体収容空間241に移動する。これにより、吸収体230が吸収した液体500が、タンク240内に収集(収容)される。押圧体253は、支持体220の内側に入ることができる突起又は突状構造体を有していてもよい。これにより効率的に吸収体230を圧縮することができる。
支持体320は、吸収体330を支持する。支持体320は、長手方向Daに延びる筒状に形成されている。支持体320は、長手方向Daに延びる筒321と、ストッパ323と、を備えている。筒321は、長手方向Daから見た断面形状が、例えば、円形、楕円形、多角形等のうちの一つになるように、形成されている。
圧縮部材350は、作業者が支持軸352を長手方向Daで吸収体330側に押すことによって、ピストン351で吸収体330を筒321内で圧縮変形させる。これにより、吸収体330から液体500が排出される。
液体500を吸収体330に吸収させる工程S31では、収集器本体310の吸収体330を液体500に接触させる。いくつかの実施形態では、収集器本体310のストッパ323に形成された流通孔324を通して、支持体320に設けられたタンク340の液体収容空間346に導入する。いくつかの実施形態では、図11に示すように、閉塞体327を支持面600上に載置し、流通孔324が形成されたストッパ323を上方に向けた状態とする。この状態で、上方から流通孔324を通して液体収容空間346内に液体500を導入してもよい。また、容器等に収集された液体500に、収集器本体310のストッパ323側の端部を浸漬させ、流通孔324を通して液体収容空間346内に液体500を導入してもよい。
液体収容空間346に導入された液体500は、液体収容空間346内の吸収体330によって吸収される。図11に示すように、吸収体330は、液体500を吸収すると筒321内で長手方向Daに膨張する。
支持体420は、吸収体430を支持する。支持体420は、長手方向Daに延びる筒状に形成されている。支持体420は、長手方向Daに延びる筒421と、ストッパ423と、を備えている。筒421は、長手方向Daから見た断面形状が、例えば、円形、楕円形、多角形等のうちの一つになるように、形成されている。
