本考案は、血液を充填した血液バツグを収納し
て、遠心分離処理する際に使用される血液バツグ
収納筒に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a blood bag storage tube used when storing blood bags filled with blood and performing centrifugal separation.
血液を収納した血液バツグを成分分離のために
遠心機にかける際、その血液バツグを遠心バケツ
トに収納することはよく知られている。
It is well known that when a blood bag containing blood is sent to a centrifuge for component separation, the blood bag is placed in a centrifugal bucket.
従来の遠心バケツトは、第５図及び第６図に示
すように、バケツト本体２０は全体が有底筒状と
なつており、その開口部２１の水平断面形状は真

て、この従来の遠心バケツトは、通常、複数セツ
トの血液バツグを収容できる程度の内容積を有し
ている。 In the conventional centrifugal bucket bag, as shown in FIGS. 5 and 6, the bucket bag main body 20 has a bottomed cylindrical shape as a whole, and the horizontal cross-sectional shape of the opening 21 is a perfect circle. A plurality of support ribs are formed in the circumferential direction of the lower end. This conventional centrifugal bucket usually has an internal volume large enough to accommodate multiple sets of blood bags.
しかしながら、従来の遠心バケツトでは、例え

液バツグを１セツトだけ入れて遠心分離をする場
合、その内容積が大きすぎ、血液バツグ表面と、
バケツト内壁との間に広い空隙部が生じることに
なる。 However, in conventional centrifugal buckets, when performing centrifugation with only one set of blood bags in the bucket, for example, when separating washed red blood cells, the internal volume is too large, and the surface of the blood bags is
A wide gap will be created between the bucket and the inner wall of the bucket.
このため、血液バツグの安定性が悪くなり、バ
ツグ上端部に設けられた輸血口、連通チユーブ等

た、強力な遠心力がかかると、血液バツグのプラ
スチツクシートが空隙部方向に延び、それがプラ
スチツクの許容強度を超えると、パンク等の破損
を起こすこともあつた。 As a result, the stability of the blood bag deteriorates, and the openings of the blood transfusion port, communication tube, etc. provided at the top of the bag fall down, which in turn causes wrinkles and bends on the top surface of the bag, resulting in this condition. If centrifugal separation is performed, blood components will not settle smoothly and will remain between the wrinkles and the like. Furthermore, when a strong centrifugal force is applied, the plastic sheet of the blood bag stretches toward the gap, and if this exceeds the allowable strength of the plastic, it can cause damage such as punctures.

連結セツトが用いられる。 On the other hand, in the above-mentioned separation of washed red blood cells, after separating red blood cells and plasma, only the supernatant plasma is discharged, and then physiological saline is introduced through the blood transfusion port and centrifugation is performed again to suspend the remaining plasma. In this case, a connection set with a saline container is used.
この連結セツトは、一端に、血液バツグの輸血

針にキヤツプを取り付けた状態で遠心処理が行わ
れている。 This connection set has one end fitted with a plastic needle that is inserted into the blood transfusion port of the blood bag, and the other end fitted with a metal needle that is inserted into the blood transfusion port of the saline container. When washing red blood cells, a plastic needle is inserted into the blood transfusion port of the blood bag, and centrifugation is performed with a cap attached to the metal needle.
しかし、従来の遠心バケツトでは前記したごと
く、血液バツグとバケツトの間に空隙部があるた

危険性がある。さらに金属針も強力な遠心力がか
かると、キヤツプが外れ、金属針が変形したり、
先端が遠心バケツトの内壁と衝突して破損するこ
ともあつた。 However, as described above, in conventional centrifugal buckets, there is a gap between the blood bag and the bucket, so if the blood bag is bent during centrifugation, there is a risk that the inserted plastic needle will break through the blood bag. Furthermore, if a strong centrifugal force is applied to a metal needle, the cap may come off and the metal needle may become deformed.
In some cases, the tip collided with the inner wall of the centrifugal bucket, causing damage.
本考案は、血液バツグを遠心バケツトとの間に
空間部が生じないように収納し、もしくは遠心バ
ケツトの代わりとして使用できる遠心処理用の血
液バツグ収納筒を提供することを目的とするもの
である。 The object of the present invention is to provide a blood bag storage cylinder for centrifugal processing that can store blood bags without creating a space between them and the centrifugal bucket, or can be used in place of the centrifugal bucket. .

For the above purpose, the present invention has the following features: The horizontal cross-sectional shape of the blood bag storage part is elliptical, support ribs extending in the height direction are provided on the outer peripheral surface of the cylinder, and support ribs protrude radially from the outer peripheral surface of the cylinder. It is characterized in that the outer diameter is configured to match the inner diameter or outer diameter of the bucket that accommodates the cylinder.

することが可能である。
Since the horizontal cross-sectional shape of the blood bag storage part of the cylinder is formed into an elliptical shape, the internal volume is narrower than that of a perfect circle in the future, and the shape approaches the blood bag shape when blood is stored in the blood bag. Therefore, even if centrifugal force is applied, the blood bag will be closely supported by the inner surface of the cylinder, and will not break even if the strength of the plastic sheet constituting the blood bag is exceeded. Furthermore, by making the outer diameter of the supporting ribs on the outer periphery of the cylinder the same as the inner diameter of the centrifugal bucket, the cylinder is stabilized when stored in the centrifugal bucket. Furthermore, by making the outer diameter of the support rib the same as the outer diameter of the centrifugal bucket, it is possible to directly store it in the centrifugal bucket mounting part of the centrifuge.

The opening 12 of this storage cylinder 10 serves as a blood bag storage section.
The horizontal cross-sectional shape is an ellipse as shown in FIG. 4, and the inner surface of the bottom is shaped to match the shape of the blood bag, as shown in FIGS. 2 and 3. As a result, when the blood bag 5 filled with blood is stored in the opening 12 of the storage cylinder 10, the blood bag 5 is held in close contact with the inner wall of the storage cylinder 10.

のである。 Next, an example of the use of the present invention will be described. First, a blood bag 5 filled with blood is stored in the blood bag storage cylinder 2. At this time, most of the outer surface of the blood bag 5 comes into close contact with the inner wall of the storage tube 2, as shown in FIGS. 2 and 3. Next, if the outer diameter of the support rib 11 of the storage tube 10 is matched to the inner diameter of the centrifugal bucket, the storage tube 10 is loaded into the centrifugal bucket shown in FIGS. 5 and 6. Also,
If the outer diameter of the support ribs 11 is matched to the outer diameter of the centrifugal bucket, the storage tube 10 is directly inserted into the centrifugal bucket attachment part of the rotary disk of the centrifuge. Thereafter, the centrifuge is rotated at a predetermined rotational speed in the same way as in the past, and the blood components in the blood bag are centrifuged.

According to the blood bag storage cylinder of the present invention as described above, since the horizontal cross-sectional shape of the cylinder is elliptical, especially when only one set of blood bags is placed in the cylinder for centrifugation, the surface of the blood bag is It is stably supported in close contact with the inner wall of the storage part, and can prevent the mouth part etc. from falling down. Therefore, wrinkles and bends can be prevented from occurring in the blood bag, and blood components remaining during centrifugation can be reduced.
