Description

【0001】
【発明の属する技術分野】
本発明は血液、髄液、***等の体液を濃縮して細胞等を採取するための器具に関し、特に濃縮***の採取に好適な体液濃縮採取具に関する。
【0002】
【従来の技術】
従来、体液を用いた遠心分離法として、血液から血小板を含む血漿を分離して赤血球を取り出す場合や、あるいは***濃縮採取法としては運動***を選択的に分離する方法としての連続または不連続密度勾配遠心法(多層Percol法,攪拌密度勾配法等)により細菌を分離した***を得る方法が用いられている。
【0003】
しかしかかる従来の方法は、遠心後にピペットを用いて上澄み液を除去する際、例えば血小板と赤血球のように比較的比重が近いものは作業中に混和が起こり易く再び混濁状態になったり、あるいは目的とする濃縮液を採取するピペットの先端が先に上澄み液の残液層を通過してくる段階で上澄み液や細菌等が付着したままだと濃縮液を採取するのに純粋な濃縮液が得られないなどの問題があった。また、***濃縮採取法の場合では精漿、密度勾配担体層の除去をピペットなどで行うため、管壁に付着した精漿、細菌等が落下、混入するという問題があった。そこで本出願人は先に特開2000−288082号において、遠心管の底部を細径化して遠心分離後***が細径底部に濃縮されるようにし、分離後、遠心管内を陰圧状態に保った状態で細径底部を切断して上澄み液を流下させることなく濃縮***を採取するための洗浄濃縮用チューブおよびその採取方法を提案した。
この洗浄濃縮用チューブおよびそれを用いる方法の採用によって、得られた濃縮液を直接的に短時間に上澄み液と完全に分離して取り出すという点で効果的であったが、細径底部を切断するという工程に作業性の点で難があり、さらに細径底部での切断が容易なように細径底部の上部に脆弱部が設けられていたが、所定通りに切断できずに割れた部分が鋭利に突出して指先に傷を付けてしまうというような事故の懸念も皆無ではなかった。

【0005】
【発明が解決しようとする課題】
本発明は、かかる従来の問題点に鑑みなされたもので、遠心分離後にピペットを差し込むような後工程を経ることをなくして分離処理後の再混和が有り得ず、得られた濃縮液を直接的にしかも短時間に採取することによって分離後の上澄み液の再混和を招く余裕を与えることなく、また遠心管の管壁に付着した上澄み液や細菌等が混入することのない濃縮体液採取具を提供するものである。
【0006】
【課題を解決するための手段】
上記課題を解決するため、本発明濃縮体液採取具は、遠心管と、濃縮用採取管と、キャップとからなり、濃縮用採取管の上端にはシリンジ接続体が一体に形成されるとともに、濃縮用採取管の先端は遠心管の底にまで達する長さとなされ、濃縮用採取管が挿入された状態で遠心管の開口部にキャップが嵌合されてなるものである。
【0007】
本発明によれば、あらかじめ遠心管内部に濃縮採取管を備えることによって、細菌を含む分離された上澄み液に触れることなく管底の濃縮液をシリンジにより直接的に簡単に吸引採取することができる。
【0008】
また本発明濃縮体液採取具は、濃縮用採取管のシリンジ接続体とキャップとが一体化されてなるものである。
【0009】
本発明によれば、濃縮体液採取具の操作性が向上する。
【0010】
さらに本発明濃縮体液採取具は、シリンジ接続部と濃縮用採取管支持部との間にフィルターが設けられてなるものである。
【0011】
本発明によれば、濃縮体液採取具の分離性能が向上する。
【0012】
そしてまた本発明濃縮体液採取具は、濃縮採取管の先端が丸みを帯びた形状になされたものである。
【0013】
本発明によれば、濃縮採取管の先端で遠心管内部をキズつけることがなくなり品質性が向上する。
【0014】
さらにまた本発明濃縮体液採取具は、濃縮用採取管を金属製の細管で構成するものである。
【0015】
本発明によれば、濃縮採取管の細管に力がかかっても撓んで力を逃がしガラス管のように少しの外力で割れるおそれがなく、安全性と操作性が向上する。
【0016】

【0022】
ここで、上記実施例の濃縮体液採取具の使用方法について、まず図4により、***の洗浄濃縮法を例にしてPercol法に基づいて詳述する。
なお、使用方法ステップを表す図4は、後述する図3の実施形態の例の場合について表したものであるが、図1,2の実施形態の例の場合においては用いられる濃縮用採取管2、シリンジ接続体3、キャップ4の実施形態が、一体化されたものであるかどうか、あるいはフィルター5を伴ったものであるかどうかなどを異にするものであり、使用方法のステップは同様に準じたものである。
【0023】
遠心管1に密度勾配担体〔ここではPercol液〕Cを入れた後、シリンジ接続体3〔図4では3b;フィルターを有するキャップ付きシリンジ接続体〕が上端に取着された濃縮用採取管2を挿入し、次に遠心管1のPercol液の上にピペット等で***Dを層積する。その後、遠心管1の開口部12にキャップ4〔ここではフィルターを有するキャップ付きシリンジ接続体3bが兼ねる。〕を施し、所定条件下で遠心する。遠心終了後、濃縮用採取管2のシリンジ接続体3にシリンジBを接続し、遠心管1の底11の濃縮***を吸引採取する。

図2において、3aはシリンジ接続体とキャップとが一体化されたキャップ付きシリンジ接続体であり、円板41aを貫通してシリンジ接続部32aが一体に形成され、そのシリンジ接続部32aの下方に濃縮用採取管支持部31aが備わっている。また円板41aの周縁には遠心管1の外形と同形状となされた外側部42aと遠心管1の内形と同形状となされた内側部43aとが設けられている。この実施形態例の濃縮用採取具も、前述の一実施形態例と同様に使用される。
【0026】
さらに、図3を参照し本発明濃縮体液採取具のさらに他の一実施形態について説明する。
【0027】
図3において、3bはフィルターを有するキャップ付きシリンジ接続体であって、シリンジ接続部32bと濃縮用採取管支持部31bとの間にフィルター5が設けられている。
【0028】
4bは濃縮用採取管支持部付きキャップであり、円板41b下方に濃縮用採取管支持部31bが備わっている。この濃縮用採取管支持部付きキャップ4bは、円板41bの周縁に遠心管1の外形と同形状となされた外側部42bと遠心管1の内形と同形状となされた内側部43bとが設けられるとともに、円板41bの上面には段部44が、周縁上方には立上り部45がそれぞれ設けられている。
【0029】
一方、シリンジ接続部32bの下端には鍔部33が設けられており、この鍔部33が濃縮用採取管支持部付きキャップ4bの立上り部45に嵌合されて、鍔部33と濃縮用採取管支持部付きキャップ4b上面の段部44との間にフィルター5が挟み込まれる。この実施形態例の濃縮用採取具も前記の一実施形態例と同様に使用される。
【0030】
【発明の効果】
以上詳述したように、本発明濃縮体液採取具は、遠心管と、濃縮用採取管と、キャップとからなり、濃縮用採取管の上端にはシリンジ接続体が一体に形成されるとともに、濃縮用採取管の先端は遠心管の底まで達する長さとなされ、濃縮用採取管が挿入された状態で遠心管の開口部にキャップが嵌合されてなるもので、あらかじめ遠心管内部に濃縮採取管を備えることにより、細菌を含む分離された上澄み液に触れることなく管底の濃縮液をシリンジで直接的に簡単に吸引採取することができる。また本発明濃縮体液採取具において、濃縮用採取管のシリンジ接続体とキャップとが一体化されたものである場合には、濃縮用採取具の操作性が向上する。さらに、シリンジ接続部と濃縮用採取管支持部との間にフィルターが設けられた場合には、濃縮用採取具の分離性能が向上する。あるいはまた、本発明濃縮体液採取具の濃縮採取管の先端が丸みを帯びた形状となされた場合には、濃縮採取管の先端部で遠心管内部をキズつけることがなく品質性が向上する。さらにはまた、本発明濃縮体液採取具において、濃縮用採取管を金属製の細管で構成させた場合には、濃縮用採取具の細管がガラス管のようにちょっとした外力で割れるおそれがなく、安全性と操作性が向上する。
【0031】
そして本発明濃縮体液採取具においては、遠心分離後にピペットを差し込むというような後工程を経ることもなく、得られた濃縮液を直接的にしかも短時間に採取できることから、例えば血液成分のように比較的比重の近いものであっても再混和を招くことなく、また本発明濃縮体液採取具に接続されたシリンジを用い分離成分を無菌状態で採取できて、例えば活動性の高い***にダメージを与えることなく集めることができることから濃縮***採取法には好適に用いられ、また本発明濃縮体液採取具を用いれば容量の異なるシリンジを使いわけることにより目的とする体液成分の採取量に応じた正確な採取がなされる。

BACKGROUND OF THE INVENTION
The present invention relates to a device for collecting cells and the like by concentrating body fluids such as blood, spinal fluid, and semen, and more particularly to a body fluid concentration and collection device suitable for collecting concentrated sperm.
[0002]
[Prior art]
Conventionally, as a centrifugal separation method using body fluids, when separating blood plasma containing platelets and removing red blood cells, or as a method for selectively separating motor sperm as a sperm concentration collection method, continuous or discontinuous density A method of obtaining sperm from which bacteria have been separated by gradient centrifugation (multilayer Percol method, stirring density gradient method, etc.) is used.
[0003]
However, when the supernatant is removed using a pipette after centrifugation, such a conventional method, for example, platelets and erythrocytes, which are relatively close in specific gravity, are likely to be mixed during the operation, or become turbid again, or When the tip of the pipette that collects the concentrated solution is first passed through the residual layer of the supernatant, a pure concentrated solution is obtained to collect the concentrated solution with the supernatant or bacteria remaining attached. There was a problem such as not being able to. In addition, in the case of the sperm concentration collection method, the seminal plasma and density gradient carrier layer are removed with a pipette or the like, so there is a problem that seminal plasma, bacteria, etc. adhering to the tube wall fall and mix. In view of this, the present applicant previously disclosed in Japanese Patent Laid-Open No. 2000-288082 that the bottom of the centrifuge tube is reduced in diameter so that the sperm is concentrated to the bottom of the reduced diameter after centrifugation, and after the separation, the inside of the centrifuge tube is kept in a negative pressure state. We proposed a washing and concentration tube and its collection method for collecting concentrated sperm without cutting the bottom of the small diameter and letting the supernatant flow down.
By adopting this washing and concentration tube and the method using it, it was effective in that the obtained concentrated solution was directly and completely separated from the supernatant in a short time, but the bottom of the small diameter was cut. The process is difficult in terms of workability, and the weak part was provided on the top of the small diameter bottom so that cutting at the small diameter bottom was easy, but the part that could not be cut as expected and cracked There was no fear of accidents that would sharply protrude and damage the fingertips.
