本案は遠沈管内の分離された上澄を傾斜操作により分取
する上澄分取装置に関する。[Detailed Description of the Invention] The present invention relates to a supernatant fractionating device for fractionating the separated supernatant in a centrifuge tube by a tilting operation.
従来、遠心分離した血液の上澄である血清を、遠沈管を
傾けてサンプルカップに分取する場合、血清の表面張力
により血清は遠沈管の外周壁にまわり込み、サンプルカ
ップに容易に分取出来ない場合があった。Conventionally, when serum, which is the supernatant of centrifuged blood, is collected into a sample cup by tilting a centrifuge tube, the surface tension of the serum causes the serum to wrap around the outer wall of the centrifuge tube, making it easy to collect into the sample cup. There were times when it wasn't possible.
本案の目的は、前述の如き欠点をなくし、この種の試料
分取の信頼性を増し血清分取が容易に確実に行うことが
出来る分取装置を提供するにある。The object of the present invention is to provide a fractionating apparatus which eliminates the above-mentioned drawbacks, increases the reliability of this type of sample fractionation, and allows serum fractionation to be carried out easily and reliably.
即ち試料分取にあたって、遠沈管外周壁に試料がまわり
込む最大の原因は試料の表面張力である。That is, during sample collection, the main reason why the sample wraps around the outer peripheral wall of the centrifuge tube is the surface tension of the sample.
したがって遠沈管口とサンプルカップロを互に接しなが
ら傾斜させて分取することにより試料の遠沈管外周壁へ
の回り込みを確実に防止しようというものである。Therefore, by tilting and fractionating the centrifuge tube opening and the sample cup while touching each other, it is possible to reliably prevent the sample from going around the outer peripheral wall of the centrifuge tube.
以下図示許施例により本案を説明する。The present invention will be explained below with reference to illustrated examples.
図において、１は遠沈管、２は遠沈管用ラックで遠沈管
１を保持するものである。In the figure, 1 is a centrifuge tube, and 2 is a centrifuge tube rack for holding the centrifuge tube 1.
３は遠沈管ラック保持器でバンドル４等により回動傾斜
が可能である。3 is a centrifuge tube rack holder which can be rotated and tilted by a bundle 4 or the like.
５はサンプルカップで遠沈管ラック保持器３と平行して
配設されたサンプルカップ用ラック６に挿入保持される
。A sample cup 5 is inserted and held in a sample cup rack 6 arranged parallel to the centrifuge tube rack holder 3.
７はサンプルラック保持器でフレーム８と一体的に形成
されている。Reference numeral 7 denotes a sample rack holder, which is formed integrally with the frame 8.
９はスプノングでサンプルカップ用ラック６の底部に配
設されブツシュピース１０を介してサンブルカツフ。Reference numeral 9 denotes a sprocket which is disposed at the bottom of the sample cup rack 6 and is inserted into the sample cup through a bushing piece 10.
５を上方に附勢する。Force 5 upward.
１１．１２は遠沈管及びサンプルカップの各々の管口で
ある。11 and 12 are the tube openings of the centrifuge tube and sample cup.
次に上記構成より成る分取装置の操作・作用を第１図及
び第２図により説明する。Next, the operation and function of the fractionation apparatus having the above structure will be explained with reference to FIGS. 1 and 2.
遠沈管ラック保持器３と固着しているバンドル４を矢印
の方向に回動すると遠沈管１は傾斜回動されて遠沈管１
内の試料が流出しない位置で、遠沈管１はサンプルカッ
プ５の管口１２に接し、更に回動が進むにつれてサンプ
ルカップ
グ９に逆らって遠沈管１により押し下げられ上澄は遠沈
管１の管口１１よりサンプルカップ５に移動する。When the bundle 4 fixed to the centrifuge tube rack holder 3 is rotated in the direction of the arrow, the centrifuge tube 1 is tilted and rotated.
The centrifuge tube 1 comes into contact with the tube opening 12 of the sample cup 5 at a position where the sample does not flow out, and as the rotation progresses further, the centrifuge tube 1 pushes down against the sample cup 9, and the supernatant is transferred to the tube of the centrifuge tube 1. It moves to the sample cup 5 from the opening 11.
従って遠沈管１の管口１１とサンプルカップ５の管口１
２は互に接しながら試料の分取が行われる為、遠沈管１
の上澄は表面張力により遠沈管１の外周壁に回り込むこ
となく確実にサンプルカップ５内に分取される。Therefore, the tube opening 11 of the centrifuge tube 1 and the tube opening 1 of the sample cup 5
Centrifuge tube 1
The supernatant is reliably collected into the sample cup 5 without going around the outer peripheral wall of the centrifuge tube 1 due to surface tension.
上記回動をモータ等により自動的に行えば、構造簡単な
分取装置の自動化が可能である。If the above-mentioned rotation is automatically performed by a motor or the like, it is possible to automate a preparative separation device with a simple structure.
以上の様に本案によれば、上澄の分取を遠沈管とサンプ
ルカップの管口を互に接しながら行えるので容易にかつ
確実に行いえるという効果がある。As described above, according to the present invention, the supernatant can be fractionated easily and reliably because the centrifuge tube and the tube opening of the sample cup are in contact with each other.
又、試料分取を遠沈管からサンプルカップへ直接移行す
るので、試料の中間汚染がなく純粋な試料が提供出来と
いう附随的効果も生じる。Further, since sample collection is directly transferred from the centrifuge tube to the sample cup, there is an additional effect that a pure sample can be provided without intermediate contamination of the sample.
