本考案は、フィルタ−を通して採血された血液を分離する場合に用いる血液バ ッグの改良に関するものである。 The present invention relates to an improvement of a blood bag used when separating blood collected through a filter.

図3は現在使用されている血液バッグ21の概略図で、採血用バッグ30の下 流に連結管22aと分岐管23bが配置され、前記分岐管23bに連結管22d を介して採血針29が接続され、前記分岐管23bの下流に接続管21a(21 b)を装着したフィルタ−32(32a)が配置され、前記フィルタ−32(3 2a)の下流に連結管32aを介して接続される血液成分分離用バッグ24、2 5が配置されている。採血された血液はフィルタ−32で各血液成分に分離され るが、フィルタ−32内のエア−が血液成分分離用バッグ24に溜まってしまい 、これらの余分なエア−をぬくことができなかった。 FIG. 3 is a schematic view of a blood bag 21 currently in use, in which a connecting pipe 22a and a branch pipe 23b are arranged in the lower stream of the blood collecting bag 30, and a blood collecting needle 29 is connected to the branch pipe 23b via a connecting pipe 22d. A filter-32 (32a) that is connected and has a connecting pipe 21a (21b) attached is disposed downstream of the branch pipe 23b, and is connected downstream of the filter-32 (32a) via a connecting pipe 32a. Blood component separation bags 24, 25 are arranged. The collected blood is separated into each blood component by the filter-32, but the air inside the filter-32 was accumulated in the blood-component separation bag 24, and these extra air could not be removed. .
【0003】 また血液バッグ21は高圧蒸気滅菌処理を施すと、フィルタ−32は一時的に 熱膨張し、常温で元の形状に戻るときに内部が陰圧になるので、連結管22a、 輸血口27、接続管28は内側に吸い込まれて潰れてしまうことがあった。この ため血液成分の移送ができないので血液の分離に使用できない場合があった。そ こで、本考案者は以上の課題を解決するために鋭意検討を重ねた結果次の考案に 到達した。Further, when the blood bag 21 is subjected to high-pressure steam sterilization treatment, the filter-32 temporarily thermally expands, and when it returns to its original shape at room temperature, the inside becomes negative pressure, so that the connecting pipe 22a, the blood transfusion port 27 and the connecting pipe 28 were sometimes sucked inward and crushed. For this reason, the blood component cannot be transferred, and thus it may not be used for separating blood. Therefore, the present inventor has made extensive studies in order to solve the above problems, and has arrived at the next inventor.

図1は本考案の血液バッグ1の概略図である。血液バッグ1は、採血針9と、 採血用バッグ10と、フィルタ−12と、血液成分分離用バッグ4と、血液成分 分離用バッグ5と、これらを接続する連結管2a(2b、2c、2d、)と、分 岐管3a(3b)から構成される。 FIG. 1 is a schematic view of a blood bag 1 of the present invention. The blood bag 1 includes a blood collecting needle 9, a blood collecting bag 10, a filter 12, a blood component separating bag 4, a blood component separating bag 5, and connecting pipes 2a (2b, 2c, 2d) connecting these. ,) And the branch pipe 3a (3b).
【0005】 採血用バッグ10の下流に連結管2aと分岐管3bが配置され、前記分岐管3 bに連結管2dを介して採血針9が接続され、前記分岐管3bの下流に接続管1 a(1b)を装着したフィルタ−12[不織布フィルタ−(直径1.0から50 μmの繊維、重さ2から5g)]が配置されている。11は連通ピ−スである。A connecting pipe 2a and a branch pipe 3b are arranged downstream of the blood collecting bag 10, a blood collecting needle 9 is connected to the branch pipe 3b via a connecting pipe 2d, and a connecting pipe 1 is provided downstream of the branch pipe 3b. A filter-12 [nonwoven fabric filter (fiber having a diameter of 1.0 to 50 μm, weight of 2 to 5 g)] equipped with a (1b) is arranged. Reference numeral 11 is a communication piece.
【0006】 前記フィルタ−12の下流に分岐管3aとこれに連結管2a、2bを介して接 続される血液成分分離用バッグ4と血液成分分離用バッグ5が配置され、前記分 岐管3aには連結管2cを介してメンブランフィルタ−6が接続されている。血 液成分分離用バッグ4(血液成分分離用バッグ5)の上端には、輸血口7と接続 管8が形成されている。また前記メンブランフィルタ−6は高圧蒸気滅菌が可能 で気体は通すが液体は通さない疎水性の材料により構成され、無菌エア−の透過 に優れた性質を有する。A branch pipe 3a, a blood component separating bag 4 and a blood component separating bag 5 connected to the branch pipe 3a via connecting pipes 2a and 2b are arranged downstream of the filter 12, and the branch pipe 3a is provided. A membrane filter-6 is connected to the via a connecting pipe 2c. A blood transfusion port 7 and a connecting pipe 8 are formed at the upper end of the blood fluid component separating bag 4 (blood component separating bag 5). Further, the membrane filter 6 is capable of high-pressure steam sterilization and is made of a hydrophobic material that allows gas to pass but does not allow liquid to pass, and has an excellent property of permeating sterile air.
【0007】 次に本考案の血液バッグの使用方法について説明する。採血針9より連結管2 dを経て血液を採血用バッグ10に収納し、採血用バッグ10をハンガ−に吊り 下げて落差によりフィルタ−12を通過させる。白血球、血小板はフィルタ−1 2に補足され、血漿成分、赤血球成分は連結管2a、分岐管3aを経て血液成分 分離用バッグ4に収納される。Next, a method of using the blood bag of the present invention will be described. Blood is accommodated in a blood collection bag 10 from a blood collection needle 9 through a connecting pipe 2d, and the blood collection bag 10 is hung on a hanger and passed through a filter 12 by a drop. White blood cells and platelets are captured by the filter-12, and plasma components and red blood cell components are stored in the blood component separation bag 4 through the connecting pipe 2a and the branch pipe 3a.
【0008】 前記フィルタ−12内のエア−は、一時的に血液成分分離用バッグ4内に導入 されるが、血液成分分離用バッグ4に外圧を加え前記エア−を連結管2a、分岐 管3a、連結管2cを経てメンブランフィルタ−6を介して外に追い出すことが できる。続いて連結管2cをクランプ、シ−ルして切断する。余分なエア−を抜 いた血液成分分離用バッグ4を遠心分離処理し、赤血球成分と血漿成分を分離し て上澄みの血漿成分を連結管2bを経て血液成分分離用バッグ5に収納する。The air in the filter 12 is temporarily introduced into the blood component separating bag 4, but external pressure is applied to the blood component separating bag 4 to connect the air to the connecting pipe 2a and the branch pipe 3a. , Through the connecting pipe 2c and through the membrane filter 6 to the outside. Subsequently, the connecting pipe 2c is clamped, sealed and cut. The blood component separating bag 4 from which excess air has been removed is subjected to a centrifugal separation process to separate the red blood cell component and the plasma component, and the supernatant plasma component is stored in the blood component separating bag 5 via the connecting pipe 2b.
【0009】 図2は本考案のその他の実施例で、図1の血液バッグ1のフィルタ−12に代 えてフィルタ−12a(中空糸型フィルタ−(内径100〜150μm、膜厚3 0〜150μm)を配置した血液バッグ1Aである。血液バッグ1Aは、フィル タ−12aで、血漿成分を濾過し赤血球成分を血液成分分離用バッグ4内に収納 するものである。その他の構成部品および使用方法は図1の血液バッグ1と実質 的に同一であるから省略する。FIG. 2 shows another embodiment of the present invention. Instead of the filter 12 of the blood bag 1 of FIG. 1, a filter 12a (hollow fiber type filter (inner diameter 100 to 150 μm, film thickness 30 to 150 μm)) The blood bag 1A is a filter 12a that filters the plasma component and stores the red blood cell component in the blood component separating bag 4. Other components and usage are as follows. Since it is substantially the same as the blood bag 1 of FIG. 1, it is omitted.
【0010】[0010]
以上説明したように本考案では、血液バッグ1(1A)は、血液成分分離用 バッグ4内の作業の妨げとなるエア−を簡単にメンブランフィルタ−6へ移すこ とができ、メンブランフィルタ−6を分岐管3aよりシ−ル切断してから、遠心 分離処理をすることができる。 As described above, in the present invention, the blood bag 1 (1A) can easily transfer the air, which hinders the work in the blood component separation bag 4, to the membrane filter 6 and the membrane filter 6 After the seal is cut from the branch pipe 3a, the centrifugal separation treatment can be performed.
【0012】 血液バッグ1(1A)は、高圧蒸気滅菌処理を施しても、蒸気(エア−)が メンブランフィルタ−6(蒸気透過性の良好なシ−ト材料から構成されている) からフィルタ−12(12a)内に吸収されるので、フィルタ−12(12a) は常温に戻っても内部は陰圧にならず、連結管、輸血口、接続管は潰れることは ない。The blood bag 1 (1A) has a vapor (air) which is filtered from the membrane filter 6 (which is made of a sheet material having a good vapor permeability) even when subjected to high-pressure steam sterilization. Since the filter 12 (12a) is absorbed into the inside of the filter 12 (12a), the inside of the filter 12 (12a) does not become negative pressure even when the temperature returns to room temperature, and the connecting pipe, the blood transfusion port, and the connecting pipe do not collapse.
