Description

【０００１】
【発明の属する技術分野】
本発明は血液を各成分に分離し、保存するための血液バッグ及び血液分離方法に関する。
【０００２】
【従来の技術】
プラスチック製のバッグに入れられた血液を遠心し、赤血球、白血球、血小板などの比重の差を利用して沈殿させ、各々の成分を取り出す血液成分の分離方法は、血液事業の分野において従来より行われていた。
【０００３】
従来血液成分分離に用いられる血液バッグは図５に示したように、プラスチック製の略長方形のバッグ本体１と、バッグ本体１に接続されたポート２と、同じくバッグ本体１と連通するよう接続された送液チューブ３、３１、３２により構成されている。また、送液チューブ３１、３２の末端には、分離した血液成分（血漿成分、白血球成分）を貯留するための子バッグ（不図示）がそれぞれ接続されてなる。
【０００４】
血液分離方法としては、採取した血液は送液チューブ３を通過してバッグ本体１に貯留された後、遠心され、図５に示したような赤血球層Ａと、血漿層Ｂと、血小板を含んだ白血球層Ｃとに分離する。そこで、バッグ本体１を加圧し、血漿層Ｂ及び白血球層Ｃを、送液チューブ３１あるいは３２を通じて各送液チューブ末端に接続された各子バッグに移送して各血液成分の分離を行う方法が一般的であった。
【０００５】
しかしながら、全血中に占める白血球層は他の成分に比して少なく、図５に示した従来の血液バッグでは赤血球層Ａと血漿層Ｂとの間に、白血球層Ｃがごく薄い層として分画される。バッグ本体１を加圧して、血漿層Ｂを送液チューブ３１あるいは３２を通じて子バッグに移送した後、白血球層Ｃを別の子バッグに移送する際、赤血球成分を白血球成分に混入させずに、あるいは赤血球成分に白血球成分を残存させずに移送することは容易ではなかった。またこのような血液分離用血液バッグは複数の子バッグが接続されてなり、構成が複雑となり、その製造工程も煩雑であった。
【０００６】
【発明が解決しようとする課題】
本発明は上記事情について鑑み、他の血液成分を混入することなく、純粋な血液成分を得ることが容易に可能となり、バッグ形状が簡単でその製造工程が簡素化することが可能な血液成分分離用血液バッグと血液成分分離方法を提供する。
【０００７】
【課題を解決するための手段】
上述の課題を解消するため、本発明にかかる血液成分分離用血液バッグは、血液を貯留するためのバッグ本体と、血液をバッグ本体内に移送するための送液チューブが接続されてなる血液成分分離用血液バッグであって、バッグ本体が第１バッグ部と第２バッグ部と第３バッグ部からなり、各バッグ部には内部の血液を送出するためのポートがそれぞれ設けられてなり、第１バッグ部と第２バッグ部はバッグ本体の両端部に、第３バッグ部はその中間部に位置し、第３バッグ部の幅の長さが第１バッグ部及び第２バッグ部の幅の長さより短い関係であることを特徴とする血液成分分離用血液バッグであって、
前記第３バッグ部において、少なくとも１つのシール部が設けられ、
前記シール部が前記第１バッグ部と前記第２バッグ部の方向に向かって配置され、前記第３バッグ部内を複数の連通する区画となるよう構成されたことを特徴とする血液成分分離用血液バッグである。
【０００８】
また、前記第３バッグ部に設けられたシール部が、複数設けられたことを特徴とする上記記載の血液成分分離用血液バッグである。
【０００９】
一方、上記血液成分分離用血液バッグにより、血液成分分離の工程の後、分離した血液成分の各層成分の境界部に沿ってバッグ本体をシールする工程と、該シール部より各バッグ部を切り離す工程とを有することを特徴とする血液成分分離方法である。
【００１０】
【発明の実施の形態】
以下に添付図面を参照して、本発明である血液成分分離用血液バッグの詳細について説明する。まず、図１を参照して、概略的な構成について説明する。図１は本発明にかかる血液成分分離用血液バッグの概略図である。本発明にかかる血液成分分離用血液バッグは、全血を貯留するバッグ本体１と、採血した血液をバッグ本体１に移送するようバッグ本体１と接続された送液チューブ３より構成される。バッグ本体１は第１バッグ部１１、第２バッグ部１２、第３バッグ部１３よりなり、第１バッグ部１１と第２バッグ部１２はそれぞれバッグの両端部に位置しており、第３バッグ部１３は第１バッグ部１１と第２バッグ部１２の中間部に位置している。また、図１に示したように、第３バッグ部１３の幅は第１バッグ部１１及び第２バッグ部１２の幅よりも短くなるような関係で構成されており、バッグ本体１の血液が貯留される箇所は略ダンベル型の形状に形成されている。また、各バッグ部には血液成分分離後にその内容物を取り出すためのポート２１、２２、２３が各バッグ部に設けられている。
【００１１】
上記構成によれば、全血を貯留したバッグ本体１を血液成分分離処理後に第１バッグ部１１と第３バッグ部１３の境界部、第３バッグ部１３と第２バッグ部１２の境界部（いずれも図１中の点線で示した２箇所）をシールした後、各バッグ部を切り離すことができる。これにより、他の血液成分が混入することなく純粋な各血液成分に分離することが可能となる。
【００１２】
また、本発明にかかる血液成分分離用血液バッグにおいて、第３バッグ部に予め設けられたシール部を有する構成とするのが好ましい。図６が示すように、第３バッグ部１３の中央部には第１バッグ部１１と第２バッグ部１２の方向にシール部５が複数設けられ、第３バッグ部１３を複数の連通する区画となるよう構成されている。これはバッグの幅をより短くすることで、各区画の貯留可能な容量は少なくなるために、結果として、白血球成分の層をより厚くさせて存在させることが可能となる。これにより白血球層を取り扱うのがより容易となり、他の血液成分との分離操作がより容易に可能となる。
【００１３】
また、これらのシール部５は、血液の分離工程において血液成分の沈降を妨げないような形状であるのが望ましい。図６に示したようなバッグの縦方向、即ち第１バッグ部１１と第２バッグ部１２の方向に、シール部５が少なくとも１つ設けられているのが望ましい。
【００１４】
血液成分分離後、バッグ本体１の外側よりシールされるシール部分４のシール方法については、公知であるいずれの技術を採用しても構わない。具体的なシール方法は、バッグ本体１の材質によって採用する方法が異なる。材質がポリエチレンやポリプロピレン等のような場合は、熱シール方法を採用するのが好ましく、材質がポリ塩化ビニルや酢酸ビニル等のような場合は、高周波ウェルダーによるシール方法を採用するのが好ましく、それぞれの材質のシール特性に応じたシール方法を採用することが好ましい。
【００１５】
一方、シール後、シール部４より各バッグ部を切り離すことがあるため、切り離し操作が容易となるよう、シール部４の中心部に薄肉部分を形成する等の処置が施されていれば好適である。また、シール器具に切り離す工程を行うことが可能な手段を設けて、実質的にシール工程と同時にシール器具により各バッグ部を切り離す工程を行っても構わない。
【００１６】
尚、従来の血液成分分離用血液バッグにおいては、血液を劣化させないような血液保存液が予め充填されているが、本発明にかかる血液成分分離用血液バッグにおいても、血液を貯留する前に予め一般的に用いられる血液保存液がバッグ本体１中に充填されていることが好ましい態様である。
【００１７】
各バッグ部における貯留容量については、バッグ本体１に貯留する全血の容量より算出される各血液成分の容量となるよう各バッグ部を形成すればよく、バッグ本体全体に貯留する全体の血液量に応じて、適宜バッグ形状（各バッグ部の幅、第１、第２バッグ部の両端部から第３バッグ部の両端部への傾斜角度等）を形成すればよい。
【００１８】
また、本発明の実施形態においてバッグ本体１全体の形状を通常の血液バッグと同様の略長方形にし、バッグ本体１の血液貯留部分を略ダンベル形状となるように形成した実施形態を示した。しかしながら、別の実施形態としてバッグ本体１全体の形状を略ダンベル形状となるように形成しても構わない（不図示）。
【００１９】
【実施例】
次に、図２から図４に本発明における血液成分分離用血液バッグの血液成分分離工程の詳細について示した。
【００２０】
採血した血液を送液チューブ３を通じてバッグ本体１に貯留した後、血液成分分離工程（通常遠心分離による血液成分分離工程）を経て、図２に示したようにバッグ本体１内にて各血液成分、即ち赤血球成分、白血球成分、血漿成分が比重の差により分離し、各層を形成する。この時、最下部に位置する第１バッグ部１１には赤血球層が、最上部に位置する第２バッグ部１２には血漿層が、そして中間部に位置する第３バッグ部１３には白血球層がそれぞれ形成される。
【００２１】
通常血液成分としての白血球は他の血液成分に比して、全血に占める割合が少なく、図５に示した従来の血液バッグにおいては、バッグ本体１内でごく薄い層として形成されることとなる。しかしながら、本発明にかかる血液成分分離用血液バッグにおいては最下部に位置する第１バッグ部１１の幅よりも中間部に位置する第３バッグ部１３の幅が短い関係にある。同様に最上部に位置する第２バッグ部１２の幅よりも中間部に位置する第３バッグ部１３の幅が短い関係にあり、バッグ本体１の形状は中間部がくびれた略ダンベル型の形状をなしている。これによれば容量の少ない白血球成分であっても、バッグ本体１内で比較的厚い層として存在させることが可能となる。
【００２２】
これにより従来バッグ本体１内で薄い層として存在していた白血球層を取り扱うのが比較的容易となり、他の血液成分との分離操作が容易に可能となる。
【００２３】
次に図３に示したように、第１バッグ部１１と第３バッグ部１３との境界部、第２バッグ部１２と第３バッグ部１３との境界部にそれぞれ位置するシール部４をバッグ本体１の外側より、別のシール器具（不図示）によりシールする。これらのシール部４はそれぞれ赤血球層と白血球層、白血球層と血漿層との境界部と一致する。そのためシール器具によりバッグ本体１の外側よりシールする際、目視にてその境界部を確認しながら、他の血液成分が混入しないようにシールし、各血液成分を分離することが容易に可能となる。このシールの工程により、各バッグ部はそれぞれ連通することのない独立した区域を形成することとなる。
【００２４】
これにより、バッグ本体内１で分離した各血液成分は、一つのバッグ内で層構造として貯留されているのではなく、それぞれシール部４により物理的に遮断されて独立したバッグ部に貯留されることとなり、各血液成分が混合されることがなくなる。
【００２５】
さらに、図４に示したようにシールの工程により形成されたシール部４より各バッグ部を切り離して、各バッグ部をそれぞれ別のバッグ体とする。各血液成分がそれぞれ別のバッグ体に貯留されていることにより、各バッグ体をそれぞれに応じて使用あるいは保存したりすることが可能となる。
【００２６】
【発明の効果】
本発明の血液成分分離用血液バッグによれば、血液成分を分離した際に白血球層に位置する第２バッグ部が他のバッグ部の幅より短く形成することにより、白血球層を比較的厚い層にて存在させることが可能となる。これによって、白血球層の存在する第３バッグ部の操作が比較的容易となる。また、各バッグ部との境界部をバッグ本体１の外側からシールし、各バッグ部内をお互いに連通しないように独立させることで、各血液成分同士が混入することがなくなり、純粋な血液成分を得ることが可能となる。さらには該シール部において切り離すことにより、各成分を別のバッグ体として、その血液成分に応じて使用することが可能となる。また、上記構成のような簡単な形状のバッグとすることによりバッグの製造工程を簡素化することが可能となる効果を奏する。

DETAILED DESCRIPTION OF THE INVENTION
Details of the blood component separating blood bag according to the present invention will be described below with reference to the accompanying drawings. First, a schematic configuration will be described with reference to FIG. FIG. 1 is a schematic view of a blood component separating blood bag according to the present invention. The blood bag for separating blood components according to the present invention includes a bag body 1 for storing whole blood and a liquid feeding tube 3 connected to the bag body 1 so as to transfer the collected blood to the bag body 1. The bag body 1 includes a first bag portion 11, a second bag portion 12, and a third bag portion 13. The first bag portion 11 and the second bag portion 12 are located at both ends of the bag, respectively. The part 13 is located in the middle part between the first bag part 11 and the second bag part 12. Further, as shown in FIG. 1, the width of the third bag portion 13 is configured so as to be shorter than the widths of the first bag portion 11 and the second bag portion 12, and the blood in the bag body 1 is The location to be stored is formed in a substantially dumbbell shape. Each bag portion is provided with ports 21, 22, and 23 for taking out the contents after blood component separation.
[0011]
According to the above configuration, the bag body 1 storing the whole blood is subjected to the blood component separation process, and the boundary portion between the first bag portion 11 and the third bag portion 13 and the boundary portion between the third bag portion 13 and the second bag portion 12 ( In either case, the two bag portions can be cut off after sealing the two places indicated by the dotted lines in FIG. Thereby, it becomes possible to separate into pure blood components without mixing other blood components.
[0012]
In the blood bag for separating blood components according to the present invention, it is preferable that the third bag portion has a seal portion provided in advance. As shown in FIG. 6, a plurality of seal portions 5 are provided in the center portion of the third bag portion 13 in the direction of the first bag portion 11 and the second bag portion 12, and the third bag portion 13 is communicated with a plurality of sections. It is comprised so that. This is because by reducing the width of the bag, the capacity that can be stored in each section is reduced, and as a result, the leukocyte component layer can be made thicker and exist. This makes it easier to handle the leukocyte layer and allows for easier separation from other blood components.
[0013]
Further, it is desirable that these seal portions 5 have a shape that does not prevent sedimentation of blood components in the blood separation step. It is desirable that at least one seal portion 5 is provided in the longitudinal direction of the bag as shown in FIG. 6, that is, in the direction of the first bag portion 11 and the second bag portion 12.
[0014]
Any known technique may be employed for the sealing method of the seal portion 4 that is sealed from the outside of the bag body 1 after blood component separation. The specific sealing method varies depending on the material of the bag body 1. When the material is polyethylene or polypropylene, it is preferable to adopt a heat sealing method, and when the material is polyvinyl chloride, vinyl acetate or the like, it is preferable to adopt a high frequency welder sealing method, It is preferable to employ a sealing method according to the sealing characteristics of the material.
[0015]
On the other hand, since each bag part may be separated from the seal part 4 after sealing, it is preferable if a measure such as forming a thin part at the center part of the seal part 4 is performed so that the separation operation is easy. is there. Moreover, the means which can perform the process of cut | disconnecting to a sealing device may be provided, and the process of cut | disconnecting each bag part with a sealing device may be performed substantially simultaneously with a sealing process.
[0016]
In the conventional blood component separation blood bag, a blood preservation solution that does not deteriorate the blood is filled in advance. However, in the blood component separation blood bag according to the present invention, the blood is stored in advance before storing the blood. It is a preferred embodiment that a blood storage solution generally used is filled in the bag body 1.
[0017]
About the storage volume in each bag part, what is necessary is just to form each bag part so that it may become the capacity | capacitance of each blood component calculated from the capacity | capacitance of the whole blood stored in the bag main body 1, and the whole blood volume stored in the whole bag main body The bag shape (width of each bag portion, inclination angle from both end portions of the first and second bag portions to both end portions of the third bag portion, etc.) may be appropriately formed.
[0018]
Further, in the embodiment of the present invention, an embodiment is shown in which the overall shape of the bag body 1 is made into a substantially rectangular shape similar to that of a normal blood bag, and the blood storage portion of the bag body 1 is formed into a substantially dumbbell shape. However, as another embodiment, the overall shape of the bag body 1 may be formed so as to have a substantially dumbbell shape (not shown).
[0019]
【Example】
Next, FIGS. 2 to 4 show details of the blood component separation step of the blood component separation blood bag according to the present invention.
[0020]
After the collected blood is stored in the bag body 1 through the liquid feeding tube 3, each blood component is passed through the blood body separation step (usually blood component separation step by centrifugation) in the bag body 1 as shown in FIG. That is, the red blood cell component, the white blood cell component, and the plasma component are separated by the difference in specific gravity to form each layer. At this time, the red blood cell layer is present in the first bag portion 11 located at the lowermost portion, the plasma layer is present in the second bag portion 12 located in the uppermost portion, and the white blood cell layer is present in the third bag portion 13 located in the middle portion. Are formed respectively.
[0021]
White blood cells as normal blood components occupy a small proportion of whole blood compared to other blood components, and the conventional blood bag shown in FIG. 5 is formed as a very thin layer in the bag body 1. Become. However, in the blood bag for separating blood components according to the present invention, the width of the third bag portion 13 located at the middle portion is shorter than the width of the first bag portion 11 located at the lowermost portion. Similarly, the width of the third bag portion 13 located in the middle portion is shorter than the width of the second bag portion 12 located in the uppermost portion, and the shape of the bag body 1 is a substantially dumbbell-shaped shape in which the middle portion is constricted. I am doing. According to this, even a white blood cell component having a small volume can be present as a relatively thick layer in the bag body 1.
[0022]
As a result, it is relatively easy to handle the white blood cell layer that has conventionally existed as a thin layer in the bag body 1, and separation operation from other blood components can be easily performed.
[0023]
Next, as shown in FIG. 3, the seal portion 4 located at the boundary portion between the first bag portion 11 and the third bag portion 13 and at the boundary portion between the second bag portion 12 and the third bag portion 13 is placed in the bag. Sealing is performed from the outside of the main body 1 by another sealing device (not shown). These seal portions 4 coincide with the boundary portions between the red blood cell layer and the white blood cell layer, and the white blood cell layer and the plasma layer, respectively. Therefore, when sealing from the outside of the bag main body 1 with a sealing device, it is possible to easily separate the blood components by sealing so that other blood components do not mix while visually checking the boundary portion. . By this sealing process, each bag portion forms an independent area that does not communicate with each other.
[0024]
Thereby, each blood component separated in the bag body 1 is not stored as a layer structure in one bag, but is physically blocked by the seal portion 4 and stored in an independent bag portion. That is, the blood components are not mixed.
[0025]
Furthermore, as shown in FIG. 4, each bag part is cut off from the seal part 4 formed by the sealing step, and each bag part is made into a separate bag body. Since each blood component is stored in a separate bag body, each bag body can be used or stored in accordance with the bag body.
[0026]
【The invention's effect】
According to the blood bag for separating blood components of the present invention, when the blood component is separated, the second bag portion located in the white blood cell layer is formed to be shorter than the width of the other bag portion, so that the white blood cell layer is a relatively thick layer. It is possible to exist at. As a result, the operation of the third bag portion where the leukocyte layer is present becomes relatively easy. In addition, by sealing the boundary with each bag part from the outside of the bag body 1 and making each bag part independent so as not to communicate with each other, each blood component is prevented from being mixed with each other, and a pure blood component is removed. Can be obtained. Furthermore, by separating at the seal portion, each component can be used as a separate bag body according to the blood component. Moreover, there exists an effect which can simplify the manufacturing process of a bag by setting it as a bag of the simple shape as the said structure.
