Description

【０００１】
【発明の属する技術分野】
この発明は、臨床診断分野の尿検査において、採取した尿検体を変性させずに長時間保存することを可能にするための方法に関するものである。
【０００２】
【従来の技術】
尿検査は、被験者に対して検体採取時の負担を与えずに測定することができるため、外来初診時及び集団検診時でのスクリーニング検査や経過観察の日常検査等において広く用いられている。
【０００３】
被験者から採取した尿検体は、内因性あるいは外因性の細菌や、酸素及び光等により比較的短時間で変性するため、採取後３〜４時間以内に測定するのが好ましいとされている。尿検体を採取後３〜４時間以上放置する場合は、密閉状態で冷蔵あるいは冷凍状態で保存する必要があり、集団検診などにおける大量の尿検体を検査する際には、一般的に冷蔵あるいは冷凍保存し、検査時に尿検体を常温状態に戻した後に測定を行う。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記尿検体は、内因性あるいは外因性の細菌により、外気中にそのまま放置しておくことで細菌が繁殖し、尿検体中の成分が変化してしまうことがある。
【０００５】
さらに、尿検体中には酸素や光に対して不安定な成分が存在するため、外気中に放置することで正確な測定ができなくなることがある。
【０００６】
特に、集団検診のように大量の尿検体を測定する場合、短時間内で測定を行うために測定者及び測定装置を常駐させるか、尿検体を冷蔵あるいは冷凍状態で密栓保管し、測定時に解凍するといった非効率的な選択をする必要が生じる。
【０００７】
また、測定手段を所有しない地域あるいは施設で採取された尿検体は、必然的に冷蔵あるいは冷凍状態で密栓保管するだけでなく、測定できる施設へ輸送する際にも、その状態を維持するといった非経済的な輸送方法が必要となってくる。
【０００８】
そこで、この発明は、上記従来の課題を解決するものであり、採取した尿検体を常温状態で数日間保存しても、尿検体中の成分が変化することなく、正確な測定が行えると共に、集団検診の際にも採取した尿検体を冷蔵あるいは冷凍などの処理を施すことなく、簡便に輸送して検査することが可能な尿検体の採取・保存方法を提供することを目的としてしてなされたものである。
【０００９】
【課題を解決するための手段】
そのため、この発明の尿検体の採取・保存方法は、採取した尿検体をろ過フィルターに通してろ過滅菌を行い、減圧密閉された回収容器の引圧により、その回収容器に回収するようにしている。
【００１０】
そして、この発明の尿検体の採取・保存方法において、ろ過フィルターを、尿中被検成分の吸着性が低い材質とし、細菌を通さず検体をろ過できる孔径にしたものとしている。
【００１１】
さらに、この発明の尿検体の採取・保存方法において、ろ過フィルターの孔径を、０．０５μｍ〜０．２μｍにしている。
【００１２】
また、この発明の尿検体の採取・保存方法において、回収容器を遮光容器にしている。
【００１３】
さらにまた、この発明の尿検体の採取・保存方法において、回収容器を、０．１気圧〜０．５気圧に減圧密閉したものとしたり、回収容器内を不活性ガスで充満させてから、減圧密閉状態にしたものとしている。
【００１４】
このようにしたこの発明の尿検体の採取・保存方法によって、採取・保存された尿検体は、ろ過滅菌が行われると共に、外気からの細菌の汚染や酸素及び光の影響による尿中成分の変性を防ぐことができ、冷蔵や冷凍などの処理をしなくても長時間保存することが可能となる。
【００１５】
【発明の実施の形態】
以下、この発明の実施形態を、図面に基づいて詳細に説明する。
【００１６】
先ず、この発明の尿検体の採取・保存方法に用いる器具は、図１、３に示すように、尿検体を採取する採尿カップ１と、尿検体のろ過フィルター２を保持したフィルターホルダー３と、栓体４によって減圧密閉された回収容器５とからなる。
【００１７】
図１に示したものでは、前記フィルターホルダー３は、内部にろ過フィルター２を保持する空間Ｓ１　を有し、上部の検体取り込み側と下部の送り出し側にそれぞれ空間Ｓ１　に連通する注射針６を取り付けたものとしている。なお、注射針６の周囲は、薄手のゴムキャップ７で覆われており、注射針６から採尿後の尿が漏れ出たり、注射針６を手指等に突き刺して怪我をしないようにしている。
【００１８】
したがって、図１に示したような尿検体の採取・保存器具を用いて、この発明の尿検体の採取・保存方法を実施すると、図２に示したように、フィルターホルダー３の上部に取り付けた注射針６を、尿検体を採取した採尿カップ１の底面１ａに突き刺し、フィルターホルダー３の下部に取り付けたもう一方の注射針６を減圧密閉された回収容器５の栓体４に突き刺すことによって、引圧により採尿カップ１に採取した尿検体はろ過フィルター２を通り、回収容器５へ流入して回収されることになる。
【００１９】
図３に示したものでは、前記フィルターホルダー３は、内部にろ過フィルター２を保持する空間Ｓ１　を有し、上部の検体取り込み側には採尿カップ１の底孔１ｂと連通する連通孔８が設けられ、下部の送り出し側にはフィルターホルダー３の空間Ｓ１　に連通する注射針６を取り付けたものとしている。なお、注射針６の周囲は、前記図１に示したものと同様に薄手のゴムキャップ７で覆われており、注射針６から採尿後の尿が漏れ出たり、注射針６を手指等に突き刺して怪我をしないようにしている。また、採尿カップ１の底部には、フィルターホルダー３を設置できる空間Ｓ２　を設け、このフィルターホルダー３が採尿カップ１の底部から突き出ないようにしている。
【００２０】
したがって、図３に示したような尿検体の採取・保存器具を用いて、この発明の尿検体の採取・保存方法を実施すると、図４に示したように、フィルターホルダー３の下部に取り付けた注射針６を、減圧密閉された回収容器５の栓体４に突き刺すことによって、引圧により採尿カップ１に採取した尿検体はろ過フィルター２を通り、回収容器５へ流入して回収されることになる。
【００２１】
前記採尿カップ１は、注射針６を刺して尿検体を回収することが可能であり、極端に液体漏れを起こさないものであれば、形状や材質は特に限定されない。
【００２２】
前記フィルターホルダー３内に保持したろ過フィルター２は、蛋白質等の尿中被検成分の吸着性が低いセルロースアセテートやポリスルホン或いはポリエーテルスルホン等を材質とし、孔径は細菌を通さず検体をスムーズにろ過できるように０．０５μｍ〜０．２μｍであるのが好ましい。
【００２３】
前記回収容器５は、空気を遮断するような材質及び構造となっており、一度容器内を窒素ガス等の不活性ガスで充満させ、減圧状態にして、合成ゴムなどの栓体４によって密栓されている。回収容器５は、尿検体がこの回収容器５内に充分量回収できる程度に減圧する必要があり、極端な減圧は圧力の維持の効率や、容器の耐久性に影響を与えるので、材質にもよるが、回収容器５内の圧力は０．１気圧〜０．５気圧にするのが好ましい。
【００２４】
また、回収容器５の大きさや形状は、一般的な尿検査装置に装着できるような、試験管形状やビン形状が好ましいが、特に限定されることはない。さらに、回収容器５は、遮光機能を持たせたものとすれば、回収した尿検体への光の影響を軽減することができるので好ましい。
【００２５】
【実施例】
以下、この発明を実施例に基づいて具体的に説明する。
【００２６】
図３に示す尿検体の採取・保存器具を用いて、この発明の尿検体の採取・保存方法を実施し、０〜７日後の尿検体中の成分を測定した。
【００２７】
先ず、採尿カップ１に尿検体Ａ〜Ｅをそれぞれ採取する。そして、それぞれのフィルターホルダー３の下部に取り付けた注射針６を、減圧密閉された回収容器５の栓体４に突き刺す。すると、回収容器５の引圧により、採尿カップ１に採取した尿検体は、ろ過フィルター２を通り、回収容器５へ流入する。その後、栓体４に突き刺した注射針６を引き抜き、栓体４をそのままにした状態で０〜７日間、室温で保存した。なお、ろ過フィルター２は、セルロースアセテートを材質にした孔径０．２μｍ、直径５０ｍｍのアドバンテック社製フィルターを用いた。また、回収容器５は、ゴム栓により栓をし、０．２気圧に減圧密閉した褐色プラスチックの試験管とした。
【００２８】
一方、比較例として、前記採尿カップ１に採取した尿検体Ａ〜Ｅの残りを、何の処理もしないまま褐色プラスチックの試験管に回収し、ゴム栓をした状態で０〜７日間、室温で保存した。
【００２９】
それぞれの検体について、栄研化学株式会社製尿検査装置（ＵＳ−３１００）を用いて、保存直後、２日後、４日後、７日後に尿中成分を測定した。測定結果は表１〜５に示す。
