Description

本発明は、液体を一次的に貯留し、貯留した液体を空気が混入しないように取り出すことのできる液体貯留容器及び液体採取器具並びに採血初流除去容器、採血器具及び血液容器に関する。
液体とは、血液、医療用の薬剤（薬液、輸液）、工業用等の一般産業用の薬剤等全てを含む。また液体は単一成分でも良いし、二成分以上の混合液体でもよい。
特に好ましい用途は、血液を採取するとともに、検査用血液の採取を容易に行うことのできる採血初流除去容器及び採血器具であるが、採血器具以外の医療分野、一般産業分野にも利用できる。 The present invention relates to a liquid storage container, a liquid collection device, a blood collection initial flow removal container, a blood collection device, and a blood container that can temporarily store liquid and take out the stored liquid so that air does not enter.
The liquid includes all of blood, medical drugs (medical solutions, infusions), general industrial drugs such as industrial use, and the like. The liquid may be a single component or a mixed liquid of two or more components.
Particularly preferred applications are a blood collection initial flow removal container and a blood collection device that can collect blood and easily collect blood for testing, but can also be used in medical fields and general industrial fields other than blood collection devices.

以下、採血初流除去容器及び採血器具の例について説明する。
採血針から採取した血液を血液容器に導入する際、供血者の穿刺位置をアルコール等で消毒を行うが、消毒を行なっても、皮膚や皮下に存在する細菌が採取した血液の中に混入することがある。
混入した細菌は、細菌の種類によっては、血液容器を保存している間にも増殖し、細菌の増殖に気づくことなく輸血などに用いられると輸血された患者に感染症などを引き起こし、重篤な事態となるおそれもある。
そこで、採取された血液の細菌汚染防止を図ることができるように、特に採血時の初流の血液を除去するシステムが発明されるようになった。 Hereinafter, examples of the blood collection initial flow removal container and the blood collection device will be described.
When blood collected from a blood collection needle is introduced into a blood container, the donor's puncture position is sterilized with alcohol, etc., but even if the sterilization is performed, bacteria existing in the skin or under the skin are mixed into the collected blood. Sometimes.
Depending on the type of bacteria, the contaminated bacteria can grow even while the blood container is stored, and if they are used for blood transfusion without noticing the growth of the bacteria, they can cause serious infections in the transfused patient. There is also a risk that this will happen.
Therefore, a system for removing the initial blood at the time of blood collection has been invented so that the collected blood can be prevented from being contaminated with bacteria.

特許文献１には、献血手順の最初において、供血者と収集容器との間の無菌性を保ちながら、検査用血液が採取できるサンプリングシステムが記載されている。
略円形の内部チャンバ５４に排出チューブ４３を伸長し、排出チューブ４３に連絡している出口ポート５０には、液体サンプルバイアル７０を保持するホルダー６０が接続できるように形成されている。また、内部チャンバ５４内で、入口ポート４６近くまで伸長した排出チューブ４３により、容器４２からサンプリングバイアルに内部チャンバ５４内部の血液等を引き出したとき、サンプリングバイアル内には空気が入らない構造となっている。 Patent Document 1 describes a sampling system that can collect test blood while maintaining sterility between a blood donor and a collection container at the beginning of a blood donation procedure.
A discharge tube 43 extends into a substantially circular inner chamber 54, and a holder 60 that holds a liquid sample vial 70 is formed so as to be connected to an outlet port 50 that communicates with the discharge tube 43. Further, when blood or the like in the internal chamber 54 is drawn from the container 42 to the sampling vial by the discharge tube 43 extending to the vicinity of the inlet port 46 in the internal chamber 54, air is not allowed to enter the sampling vial. ing.

特許文献２から特許文献５には、採取した採血初流を採取することができる容器連結体について記載されており、採血血液の細菌検査の精度と、細菌検査における作業性とを向上できるとともに、採血血液を使用する際の安全性を向上することができる旨が記載されている。
具体的には、例えば特許文献４において、チューブ１５により接続された採血容器１０と採血針１５２を有する採血器具１の、チューブ１５の途中に形成した分岐コネクタ９２にはチューブ９１が接続され、その端部には血液を一時的に収納する血液容器２０が接続されている。この容器２０には、先端にサンプリングポート７１が形成されているチューブ９６が接続されている。採血器具１は、採取した初流血液をサンプリングポート７１に接続した採血管へ、容易で安全に導入して細菌検査を行うことができるので、細菌検査の信頼性が高くなるというものである。 Patent Document 2 to Patent Document 5 describe a container assembly that can collect a collected blood initial flow, and can improve the accuracy of a bacterial test of the collected blood and the workability in the bacterial test, It is described that the safety when using the collected blood can be improved.
Specifically, for example, in Patent Document 4, a tube 91 is connected to a branch connector 92 formed in the middle of the tube 15 of the blood collection device 1 having the blood collection container 10 and the blood collection needle 152 connected by the tube 15, A blood container 20 for temporarily storing blood is connected to the end. A tube 96 having a sampling port 71 formed at the tip is connected to the container 20. Since the blood collection device 1 can easily and safely introduce the collected initial blood into a blood collection tube connected to the sampling port 71 and perform a bacterial test, the reliability of the bacterial test is increased.

また、特許文献６には、採血容器３２内に仕切部４０を形成することで血液成分の収納室４２と血液成分の下層の流出路４１に分画した血液容器が記載されている。仕切部４０が形成する通路３９の上流近傍には、閉塞部材１０、２０、４３が装着される。
仕切部４０で血液容器内を分画することにより、遠心分離処理による上層・中間層・下層に分離後、各血液成分が互いに混入しない状態を維持しながら、中間層が血液容器３２に残るように、上層は上部流出口３９ａから分離容器３３へ、下層は閉塞部材１０、２０、４３を破壊し、仕切部４０により形成される流出路４１を経て流出口３９ｂ、分離容器３４へと分離排出させることができる。 Patent Document 6 describes a blood container that is partitioned into a blood component storage chamber 42 and a blood component lower outlet channel 41 by forming a partition 40 in the blood collection container 32. In the vicinity of the upstream side of the passage 39 formed by the partition portion 40, the closing members 10, 20, and 43 are mounted.
By dividing the blood container with the partition 40, the intermediate layer remains in the blood container 32 while maintaining the state in which the blood components are not mixed with each other after separation into an upper layer, an intermediate layer, and a lower layer by centrifugation. In addition, the upper layer breaks down the blocking members 10, 20, 43 from the upper outlet 39 a to the separation container 33, and separates and discharges to the outlet 39 b and the separation container 34 via the outflow passage 41 formed by the partition 40. Can be made.

特許文献１の発明では、容器４２内の血液を採取する際、排出チューブ４３により、サンプリングシステムを逆さにしても空気を取り込みにくいが、排出チューブ４３内部の空気をサンプリングバイアルに取り込むことを防止できない。また、排出チューブ４３を介して血液を取り込むため、サンプリングバイアルには少量ずつしか血液を取り込めず、容器４２からサンプリングバイアルへの血液採取作業が迅速に行うことができない。また、容器４２内の血液を採取する際、サンプリングシステムを必ず逆さにしなければいけないという制限がある。
特許文献２から特許文献５の発明では、初流血液の除去、血液のサンプリングはでき得るものの、容器の構成上、供血者からの採血時には、採血用器具が低位置にあるため、作業者が屈みこんだりしゃがんだりといった無理な体勢から、血液をサンプリングしなければならず、特に献血車などの狭い場所で、何度も同様の作業を行なうのは、非常に苦痛となる。
また、特許文献６の、容器３１内に形成されている仕切部４０は、分離した血液の流出口であり、閉塞部材１０、２０、４３の装着を必要としている。 In the invention of Patent Document 1, when collecting blood in the container 42, it is difficult to take in air even if the sampling system is inverted by the discharge tube 43, but it is not possible to prevent the air inside the discharge tube 43 from being taken into the sampling vial. . Further, since blood is taken in through the discharge tube 43, blood can be taken into the sampling vial little by little, and blood collection work from the container 42 to the sampling vial cannot be performed quickly. Further, there is a restriction that the sampling system must be inverted when collecting blood in the container 42.
In the inventions of Patent Document 2 to Patent Document 5, although the removal of initial blood and blood sampling can be performed, the blood collection device is in a low position when collecting blood from a blood donor due to the configuration of the container. Blood must be sampled from an unreasonable posture such as crouching or crouching, and it is very painful to perform the same work many times in a narrow place such as a blood donation car.
Moreover, the partition part 40 formed in the container 31 of patent document 6 is an outflow port of the isolate | separated blood, and mounting | wearing of the obstruction | occlusion members 10, 20, and 43 is required.

本発明が解決しようとする課題は、採血初流除去容器に貯留した血液を真空採血管ホルダ等の外部への血液採取手段から真空採血管に採取する際、真空採血管内にどうしても空気を取り込んでしまう点、また空気を取り込まないようにするためには、血液容器の構成上、採血時には採血初流除去システムが低位置にあることから、作業者が屈みこんだりしゃがんだりといった無理な体勢から血液をサンプリングしなければならない点、また、従来は初流血除去容器に血液が規定量採血できたことを容器につけられた印と血液の液面が一致することによって確認していたが、誤差が大きく、採血に過不足が生じる場合がある点である。   The problem to be solved by the present invention is that when the blood collected in the blood collection initial flow removal container is collected into the vacuum blood collection tube from the blood collection means to the outside such as a vacuum blood collection tube holder, air must be taken into the vacuum blood collection tube. In order to prevent air from being taken in, the structure of the blood container makes the blood flow from an unreasonable posture, such as crouching or crouching, because the initial blood removal system is low when collecting blood. In the past, it was confirmed that a specified amount of blood could be collected in the primary blood removal container by matching the mark on the container with the blood level. In other words, excessive or insufficient blood collection may occur.

Furthermore, (3) it can be easily determined that the prescribed amount of blood to be collected in the blood collection initial flow removal container B has been collected.

以下、採血初流除去容器及び採血器具の例について説明する。
図１は、採血器具１の概略図、図２は、血液容器２の概略図である。図３は、図１のその他の実施例を示す採血器具１Ａの概略図である。
［採血器具１］
採血器具１は、採血時等に、供血者の初流血液を採血初流除去容器Ｂに採ることで、針穿刺部の皮膚や皮下に存在する細菌等の混入を防止するとともに、容器Ｂ内に採取した初流血液を検査用の血液としても用いるためのものである。
この採血器具１は、採血初流除去容器Ｂと血液採取手段（例えば後述する採血管ホルダ２２）とからなり、例えば図２の血液容器２において、採血チューブＴ１の途中に配置された分岐管１３ａに接続された初流血液導入チューブＴ２の下流（端部）に接続される。 Hereinafter, examples of the blood collection initial flow removal container and the blood collection device will be described.
FIG. 1 is a schematic diagram of a blood collection device 1, and FIG. 2 is a schematic diagram of a blood container 2. FIG. 3 is a schematic view of a blood collection device 1A showing another embodiment of FIG.
[Blood collection instrument 1]
The blood collection device 1 prevents the contamination of bacteria or the like existing in the skin of the needle puncture part or under the skin by collecting the initial blood of the donor in the blood collection initial flow removal container B at the time of blood collection or the like. In this case, the initial blood sampled in the above is also used as blood for testing.
This blood collection device 1 includes a blood collection initial flow removal container B and blood collection means (for example, a blood collection tube holder 22 described later). For example, in the blood container 2 of FIG. 2, a branch tube 13a disposed in the middle of the blood collection tube T1. Is connected to the downstream (end portion) of the initial blood introduction tube T2 connected to.

［採血初流除去容器Ｂ］
採血初流除去容器Ｂには、供血者より採取した初流血液を貯留する。
採血初流除去容器Ｂの容器本体２１の上部には、採取する初流血液を容器本体２１内に取り込むための入口２３が形成され、容器本体２１の下部には、採取した血液を取り出すための出口２４が形成されている。
容器本体２１内部に、例えば熱溶着等の手段により、第１仕切部Ｐ１、第２仕切部Ｐ２および第３仕切部Ｐ３を形成している。
第１仕切部Ｐ１と第２仕切部Ｐ２は、容器本体２１の略縦方向に形成し、第３仕切部Ｐ３は、容器本体２１の略横方向または略斜め方向に形成している。このようにして容器本体２１内部を、血液溜Ｓ１と空気溜Ｓ２に区画している。「略横方向または略斜め方向」に形成するとは、単に横方向のみ、または斜め方向に形成しても良いし、図１に例示するように、全体が略Ｓ字状となるように、左側及び／又は右側に曲線状（直線状でもよい）の仕切部を上及び／又は下方向に形成してもよいことを意味する。
第１仕切部（Ｐ１）と第２仕切部（Ｐ２）の間に、上開放部（Ｏ１）と下開放部（Ｏ２）と空気通路（Ｗ２）を形成している。
第３仕切部（Ｐ３）と容器本体（２１）の上側周辺部（Ｒ）（単に上側部という場合もある）の間に、下開放部（Ｏ２´）と血液通路（Ｗ２）を形成している。
空気通路（Ｗ２）は、上開放部（Ｏ１）と下開放部（Ｏ２）を経て、血液溜（Ｓ１）と空気溜（Ｓ２）と連通している。
血液通路（Ｗ１）は、初流血液の入口（２３）と下開放部（Ｏ２´）を経て、血液溜（Ｓ１）と連通している。
初流血液を空の容器本体２１の血液溜Ｓ１に貯留する時、血液は前記血液通路Ｗ１を通り血液溜Ｓ１に貯留する。血液通路Ｗ１は血液を確実に血液溜りに導き血液が空気より先に前記空気通路Ｗ２へ混入することを防止する。
血液溜Ｓ１内の空気は、前記上開放部Ｏ１、空気通路Ｗ２、下開放部Ｏ２を経て、前記空気溜Ｓ２へ収納される。
空気通路Ｗ２の幅は、２〜５ｍｍ程度に設定して形成するのが好ましい。また空気通路Ｗ２の途中の一部に狭窄部Ｗ２ａを形成して、狭くすることにより、空気と血液の流体抵抗の差を利用して、空気は通りやすく血液は通りにくい構造にすることも好ましい。このときの狭くなった部分は通路の直径が０．５〜２ｍｍ程度が適当である。この部分は血液が規定量採血されたときに空気に続いて血液が通り抜ける位置に成形することが好ましい。また空気通路Ｗ２を一部狭くするかわりに逆流防止弁等（例えばあひるのくちばし弁等の一方向弁）を設けるのもよい。
これらの構造は血液が規定量に達したときに採血速度を低減させ血液の過量採取を防止する目的、及び一度空気溜Ｓ２へ移動させた空気が、真空採血管ホルダ２２から真空採血管に採取する際などに逆流することを防止する目的で成形する。 [Blood collection initial flow removal container B]
In the initial blood collection container B, the initial blood collected from the blood donor is stored.
An inlet 23 for taking the initial blood to be collected into the container body 21 is formed in the upper part of the container main body 21 of the blood collection initial flow removal container B, and a lower part of the container main body 21 is used for taking out the collected blood. An outlet 24 is formed.
Inside the container main body 21, the 1st partition part P1, the 2nd partition part P2, and the 3rd partition part P3 are formed by means, such as heat welding, for example.
The first partition portion P1 and the second partition portion P2 are formed in a substantially vertical direction of the container body 21, and the third partition portion P3 is formed in a substantially horizontal direction or a substantially oblique direction of the container body 21. In this way, the inside of the container body 21 is partitioned into a blood reservoir S1 and an air reservoir S2. Forming in “substantially horizontal direction or substantially diagonal direction” may be formed only in the horizontal direction or in the diagonal direction, and as illustrated in FIG. 1, the left side so that the whole is substantially S-shaped. It means that a curved (or straight) partition may be formed on the right side and / or on the right side.
An upper opening (O1), a lower opening (O2), and an air passage (W2) are formed between the first partition (P1) and the second partition (P2).
A lower open part (O2 ′) and a blood passage (W2) are formed between the third partition part (P3) and the upper peripheral part (R) of the container body (21) (sometimes simply referred to as the upper part). Yes.
The air passage (W2) communicates with the blood reservoir (S1) and the air reservoir (S2) through the upper opening portion (O1) and the lower opening portion (O2).
The blood passage (W1) communicates with the blood reservoir (S1) through the inlet (23) of the primary blood and the lower opening (O2 ′).
When the initial blood is stored in the blood reservoir S1 of the empty container body 21, the blood passes through the blood passage W1 and is stored in the blood reservoir S1. The blood passage W1 reliably guides the blood to the blood pool and prevents the blood from being mixed into the air passage W2 before the air.
The air in the blood reservoir S1 is stored in the air reservoir S2 through the upper opening O1, the air passage W2, and the lower opening O2.
The width of the air passage W2 is preferably set to about 2 to 5 mm. It is also preferable to form a narrowed portion W2a in the middle of the air passage W2 so as to make it narrow so that air can be easily passed and blood cannot be easily passed using the difference in fluid resistance between air and blood. . In this case, it is appropriate that the narrowed portion has a passage diameter of about 0.5 to 2 mm. This portion is preferably formed at a position where blood passes through the air when a prescribed amount of blood is collected. Further, instead of partially narrowing the air passage W2, a check valve or the like (for example, a one-way valve such as a duck beak valve) may be provided.
These structures are intended to reduce the blood collection rate when blood reaches a specified amount and prevent excessive collection of blood, and once the air has been moved to the air reservoir S2, it is collected from the vacuum blood collection tube holder 22 into the vacuum blood collection tube. Molding is performed for the purpose of preventing backflow during the process.

空気通路Ｗ２の幅が狭すぎると、血液を採取する際に、空気溜Ｓ２へと空気がスムーズに移動できない可能性があり、逆に空気通路Ｗ２があまり広すぎると、空気が確実に空気溜Ｓ２に移動できない、または一度空気溜Ｓ２へ移動させた空気が、真空採血管ホルダ２２から真空採血管に採取する際などに逆流するおそれがあるため好ましくない。
さらに、上開放部Ｏ１（非溶着部分）についても、空気通路Ｗ２の幅の設定と同様の理由により、２〜５ｍｍ程度に設定するのが好ましい。
なお、下開放部Ｏ２（非溶着部分）は、血液溜Ｓ１に初流血液が流入する際、追いやられた容器本体２１内の空気が溜まるスペース（空気溜Ｓ２）と連通しているので、空気が貯留可能なように上開放部Ｏ１（非溶着部分）よりも広く（大きく）形成するのが好ましい。
また空気溜Ｓ２を十分広く成形すると、採血時に容器や空気による弾力が、流入する血液を押し戻そうとする力が働くことがなく採血量が不足する恐れが少なくなるため好ましい。
さらに血液溜Ｓ１の容積を、採取すべき血液の規定量と実質的に同じになるように製作・形成することにより、血液溜Ｓ１内に血液が満杯になったとき、血液が空気溜Ｓ２へとあふれる瞬間に、規定量に達したことを容易に確認できる。 If the width of the air passage W2 is too narrow, there is a possibility that the air cannot smoothly move to the air reservoir S2 when blood is collected, and conversely if the air passage W2 is too wide, the air is surely collected. This is not preferable because the air that cannot be moved to S2 or once moved to the air reservoir S2 may flow backward when being collected from the vacuum blood collection tube holder 22 into the vacuum blood collection tube.
Furthermore, it is preferable to set the upper open portion O1 (non-welded portion) to about 2 to 5 mm for the same reason as the setting of the width of the air passage W2.
Note that the lower open portion O2 (non-welded portion) communicates with a space (air reservoir S2) in which air in the container body 21 that has been repelled when the initial blood flows into the blood reservoir S1. It is preferable to form wider (larger) than the upper open portion O1 (non-welded portion) so that can be stored.
In addition, it is preferable to form the air reservoir S2 sufficiently wide, because the elasticity of the container and air during blood collection does not cause a force to push back the inflowing blood and there is less possibility of insufficient blood collection.
Further, by producing and forming the blood reservoir S1 so that the volume of the blood reservoir S1 is substantially the same as the prescribed amount of blood to be collected, when the blood is full in the blood reservoir S1, the blood is transferred to the air reservoir S2. At the moment of overflowing, you can easily confirm that the specified amount has been reached.

［外部容器への血液採取手段］
採血初流容器Ｂ内に採取した血液を、検査等のために外部容器へ採取する手段として、容器本体２１の出口２４に、真空採血管ホルダ２２またはコネクタ付きチューブ（チューブ先端にコネクタを接続したもの）を形成しても良い。要するに、外部容器に血液を採取することが可能であれば、何でも良い。
例えば血液を外部容器に採取する具体的な手段として、例えば、図１に示すような真空採血管ホルダ２２を採用する場合、出口２４に、初流血液の採取針２５が装着され、採取針２５の外周に真空採血管ホルダ２２が装着される。採取針２５はシース２６で覆われる。
容器本体２１の血液溜Ｓ１内に血液を採取後、真空採血管ホルダ２２に真空採血管（図示せず）を差し込んで、容器本体２１内の血液を真空採血管に回収する。 [Blood collection means in external container]
As means for collecting the blood collected in the initial blood collection container B into an external container for examination or the like, a vacuum blood collection holder 22 or a tube with a connector (connector is connected to the tube tip) at the outlet 24 of the container body 21. May be formed. In short, anything can be used as long as blood can be collected in an external container.
For example, when a vacuum blood collection tube holder 22 as shown in FIG. 1 is employed as a specific means for collecting blood in an external container, for example, a first blood collection needle 25 is attached to the outlet 24, and the collection needle 25 A vacuum blood collection tube holder 22 is attached to the outer periphery of the tube. The collection needle 25 is covered with a sheath 26.
After collecting blood in the blood reservoir S1 of the container main body 21, a vacuum blood collection tube (not shown) is inserted into the vacuum blood collection tube holder 22, and the blood in the container main body 21 is collected in the vacuum blood collection tube.

［血液容器２］
血液容器２は、例えば図２に示すように、親容器４、採血器具１、血液フィルタ３、第１子容器５、第２子容器６及び赤血球保存液入容器７から構成される。
親容器４の上流には、採血チューブＴ１が接続されている。採血チューブＴ１には、先端（上流）からその途中にわたって、採血針８、分岐管１３ａ及び流路閉塞手段１２が接続・配置されている。分岐管１３ａには、初流血液導入チューブＴ２（途中にクランプ１１を装着）を介して採血器具１が接続される。
流路閉塞手段１２は、図１に例示するように採血チューブＴ１の内側に配置される連通ピース１２（一部を破断して液体流路を開通するもの）でも良いし、図１に例示するように各チューブＴ１、Ｔ２、Ｔ３の外側に装着し、その開閉により液体流路を開通・閉塞できるクランプ１１ａ、１１ｂ、１１ｃでも良い。
さらに親容器４の下流には、連結チューブＴ３を介して血液フィルタ３及び第１子容器５を接続している。さらに第１子容器５は、連結チューブＴ４、分岐管１３ｂ、連結チューブＴ５、Ｔ６を介して、第２子容器６、赤血球保存液入容器７を接続している。
親容器４及び赤血球保存液入り容器７には、採血時または輸血保存時における血液の凝固の防止または保存のために、例えばＡＣＤ液、ＣＰＤ液、ＭＡＰ液のような抗凝固剤または赤血球保存液を収納している。 [Blood container 2]
For example, as shown in FIG. 2, the blood container 2 includes a parent container 4, a blood collection device 1, a blood filter 3, a first child container 5, a second child container 6, and a red blood cell storage solution container 7.
A blood collection tube T 1 is connected upstream of the parent container 4. A blood collection needle 8, a branch pipe 13a, and a flow path blocking means 12 are connected and arranged from the tip (upstream) to the middle of the blood collection tube T1. The blood collection device 1 is connected to the branch tube 13a via the first-stream blood introduction tube T2 (with the clamp 11 attached in the middle).
As illustrated in FIG. 1, the channel closing means 12 may be a communication piece 12 (one that partially breaks and opens the liquid channel) disposed inside the blood collection tube T <b> 1, and is illustrated in FIG. 1. Thus, the clamps 11a, 11b, and 11c that are attached to the outside of the tubes T1, T2, and T3 and can open and close the liquid flow path by opening and closing the tubes may be used.
Further, the blood filter 3 and the first child container 5 are connected to the downstream of the parent container 4 via a connecting tube T3. Furthermore, the 1st child container 5 has connected the 2nd child container 6 and the erythrocyte preservation solution storage container 7 via the connection tube T4, the branch pipe 13b, and connection tube T5, T6.

［採血器具１（採血初流除去容器Ｂ）の使用例］
（１）供給者より採血された初流血液は、供血者に穿刺した採血針８から分岐管１３ａ、チューブＴを経て、容器本体２１の血液通路Ｗ１を通って血液溜Ｓ１に貯留される。血液が貯留されるに従い、容器本体２１内の空気は血液に追いやられて、血液溜Ｓ１内の空気は、上開放部Ｏ１、空気通路Ｗ２、下開放部Ｏ２を経て、空気溜Ｓ２へ収納される。
（２）初流血液の採取が規定量に達した時点で、クランプ１１ａを閉じ、採血初流除去容器Ｂへの血液の流れを遮断するとともに、連通ピース１２を破断して、親容器４に血液を貯留する。
（３）一方、容器本体２１の血液溜Ｓ１内に貯留した血液を、容器本体２１の出口２４に接続される真空採血管ホルダ２２から真空採血管へと採取する。
バック本体２１を倒立させたとき、血液溜Ｓ１の血液は、上開放部Ｏ１、空気通路Ｗ２、下開放部Ｏ２を経て、空気溜Ｓ２内に侵入し、その後、血液溜Ｓ１と空気溜Ｓ２内の流体圧力が、実質的に平衡状態となる。空気溜Ｓ２に血液が存在する状態では、空気溜Ｓ２内の空気は、空気通路Ｗ２を経て血液溜Ｓ１方向へは逆流せず、空気溜Ｓ２内に閉じ込められる。
その際、作業者が、屈んだりしゃがみこんだりすることなく、立ち上がった楽な姿勢のまま、採血初流除去容器Ｂを逆さにして真空採血管への採取作業を行っても、空気溜Ｓ２へ収納された空気は、下開放部Ｏ２、空気通路Ｗ２、上開放部Ｏ１を経て、血液溜Ｓ１に再び空気が入り込むことはなく、したがって真空採血管へ空気が混入することもない。 [Usage example of blood collection device 1 (blood collection initial removal container B)]
(1) The initial blood collected from the supplier is stored in the blood reservoir S1 through the blood collection needle 8 punctured by the blood donor, the branch tube 13a, the tube T, and the blood passage W1 of the container body 21. As the blood is stored, the air in the container body 21 is driven to the blood, and the air in the blood reservoir S1 is stored in the air reservoir S2 via the upper opening O1, the air passage W2, and the lower opening O2. The
(2) When the collection of the initial flow blood reaches a specified amount, the clamp 11a is closed to block the flow of blood to the blood collection initial flow removal container B, and the communication piece 12 is broken to return to the parent container 4. Stores blood.
(3) On the other hand, the blood stored in the blood reservoir S1 of the container body 21 is collected from the vacuum blood collection tube holder 22 connected to the outlet 24 of the container body 21 to the vacuum blood collection tube.
When the back body 21 is inverted, the blood in the blood reservoir S1 enters the air reservoir S2 through the upper opening O1, the air passage W2, and the lower opening O2, and then enters the blood reservoir S1 and the air reservoir S2. Are substantially in equilibrium. In the state in which blood is present in the air reservoir S2, the air in the air reservoir S2 does not flow backward in the direction of the blood reservoir S1 via the air passage W2, but is confined in the air reservoir S2.
At that time, even if the operator performs the sampling operation to the vacuum blood collection tube by inverting the blood collection initial flow removal container B while keeping the standing posture in an easy posture without bending or squatting down, it is stored in the air reservoir S2. The air thus passed does not enter the blood reservoir S1 again via the lower opening O2, the air passage W2, and the upper opening O1, and therefore air does not enter the vacuum blood collection tube.

採血初流除去容器Ｂは、前記説明、図１に例示した形態のみに限定されない。要するに、空気通路Ｗ２の幅、第１仕切部Ｐ１の上開放部Ｏ１（非溶着部分）、第２仕切部Ｐ２の下開放部Ｏ２（非溶着部分）及び第３仕切部Ｐ３の下開放部Ｏ２´（非溶着部分）の大きさ（長さ、広さ）等は、初流血液を空の容器本体２１の血液溜Ｓ１に貯留する時、血液溜Ｓ１内の空気が、上開放部Ｏ１、空気通路Ｗ２、下開放部Ｏ２を経て、空気溜Ｓ２へ収納され、血液を取り出す時も含めて、空気溜Ｓ２に収納された空気が、下開放部Ｏ２、空気通路Ｗ２、上開放部Ｏ１を経て血液溜Ｓ１内に逆流しない形態であれば何でも良い。   The blood collection initial flow removal container B is not limited to the form illustrated in the above description and FIG. In short, the width of the air passage W2, the upper opening portion O1 (non-welded portion) of the first partition portion P1, the lower opening portion O2 (non-welding portion) of the second partition portion P2, and the lower opening portion O2 of the third partition portion P3. The size (length, width) etc. of ′ (non-welded part) is such that when the initial flow blood is stored in the blood reservoir S1 of the empty container body 21, the air in the blood reservoir S1 is changed to the upper open portion O1, The air stored in the air reservoir S2 is stored in the air reservoir S2 through the air passage W2 and the lower open portion O2, and the air stored in the air reservoir S2 passes through the lower open portion O2, the air passage W2, and the upper open portion O1. Any configuration may be used as long as it does not flow back into the blood reservoir S1.

When the back body 21 is inverted, the blood in the blood reservoir S1 enters the air reservoir S2 through the lower opening O2, the air passage W2, and the upper opening O1, and then the fluid in the blood reservoir S1 and the air reservoir S2. The pressure is substantially in equilibrium. In the state where blood is present in the lower part of the air reservoir S2, the air in the air reservoir S2 is confined in the air reservoir S2 without flowing backward in the direction of the blood reservoir S1 via the air passage W2.
Since other shapes, usage methods, and the like are substantially the same as the blood collection initial flow removal container B (blood collection device 1) illustrated in FIG. 1, detailed description thereof is omitted.

Is formed continuously from the lower part to substantially the lower part of the third partition part P3. In other words, the portion below the intersection of the third partition P3 and the first partition P1 is deleted.

(E) to (F): The blood collection initial flow removal container BA ′ is inverted (inverted), and a vacuum blood collection tube (not shown) is attached to the collection needle 25 of the vacuum blood collection tube holder 22 to collect the initial flow blood. To do.
When the back body 21 is inverted, the blood in the blood reservoir S1 enters the air reservoir S2 through the lower opening O2, the air passage W2, and the upper opening O1, and then the fluid in the blood reservoir S1 and the air reservoir S2. The pressure is substantially in equilibrium. In the state where blood is present in the lower part of the air reservoir S2, the air in the air reservoir S2 is confined in the air reservoir S2 without flowing backward in the direction of the blood reservoir S1 via the air passage W2.
The initial blood in the air reservoir S2 gradually moves to the blood reservoir S1 through the upper opening O1, the air passage W2, and the lower opening O2, as shown in FIG. (Not shown).
The air in the air reservoir S2 is completely sealed in the air reservoir S2, and does not move to the blood reservoir S1 through the upper opening O1, the air passage W2, and the lower opening O2.

図６に例示した採血初流除去容器ＢＤ（採血器具１Ｄ）は、図４に例示した採血初流除去容器ＢＡ´（採血器具１Ａ´）において、第２仕切部Ｐ２の上部に空気、初流血液を空気溜Ｓ２内に誘導する誘導部Ｒを形成している。
さらに詳述すれば、誘導部Ｒは空気溜Ｓ２方向に湾曲（カーブ）して形成されている。
さらに採血初流除去容器ＢＤ（容器本体２１）の上部壁面ＷＤの下部に、空気、初流血液を空気溜Ｓ２内に誘導する誘導壁面ＷＣを形成したものである。さらに詳述すれば、誘導壁面ＷＣは、第３仕切部Ｐ３の上部に沿って、下方に傾斜して形成される。傾斜は図６に例示するように、（若干）湾曲（カーブ）させても良いし、ストレートでも良い。
また空気通路の狭窄部Ｗ２ａは、省略されているが、必要であれば形成しても良い。
その他の形状等は、図６に例示した採血初流除去容器ＢＡ´（採血器具１Ａ´）と実質的に同じであるから、詳細な説明は省略する。 The blood collection initial flow removal container BD (blood collection device 1D) illustrated in FIG. 6 is the same as the blood collection initial flow removal container BA ′ (blood collection device 1A ′) illustrated in FIG.

As illustrated in FIG. 6, the inclination may be (slightly) curved (curved) or straight.
Further, the narrowed portion W2a of the air passage is omitted, but may be formed if necessary.
Other shapes and the like are substantially the same as the blood collection initial flow removal container BA ′ (blood collection device 1A ′) illustrated in FIG.

［採血初流除去容器ＢＤの使用例］
図６の採血初流除去容器ＢＤの使用例方法の一例を図７を参照して説明する。
（Ａ）から（Ｂ）：初流血液を、入口２３から血液通路Ｗ１、下開放部Ｏ２´を経て血液溜Ｓ１の中へ導入する。血液溜Ｓ１の空気は、下開放部Ｏ２、空気通路Ｗ２、上開放部Ｏ１を経て、空気溜Ｓ２の中へ導入される。
（Ｃ）：さらに初流血液の導入を継続すると、初流血液は、下開放部Ｏ２、空気通路Ｗ２、誘導部Ｒ、上開放部Ｏ１、誘導壁面ＷＣを経て、空気溜Ｓ２の中へ一部導入される。（Ｄ）から（Ｅ）：採血初流除去容器ＢＡ´を反転（倒立）させて、真空採血管ホルダ２２の採取針２５に真空採血管（図示せず）を装着し、初流血液を採取する。
バック本体２１を倒立させたとき、血液溜Ｓ１の血液は、下開放部Ｏ２、空気通路Ｗ２、上開放部Ｏ１から空気溜Ｓ２内に侵入し、その後、血液溜Ｓ１と空気溜Ｓ２内の流体圧力が、実質的に平衡状態となる。空気溜Ｓ２の下部に血液が存在する状態では、空気溜Ｓ２内の空気は、空気通路Ｗ２を経て、血液溜Ｓ１方向へは逆流せず、空気溜Ｓ２内に閉じ込められる。
当初は（Ｄ）のように、初流血液は、空気溜Ｓ２に一次的に導入されるが、次第に（Ｆ）のように、誘導壁面ＷＣ、上開放部Ｏ１、誘導部Ｒ、空気通路Ｗ２、下開放部Ｏ２を経て、血液溜Ｓ１に移動し、採取針２５を経て真空採血管（図示せず）に採取される。空気溜Ｓ２の空気は、空気溜Ｓ２内に完全に封止込められ、誘導壁面ＷＣ、上開放部Ｏ１、誘導部Ｒ、空気通路Ｗ２、下開放部Ｏ２を経て、血液溜Ｓ１に移動することはない。
採血初流除去容器ＢＤでは、「誘導部Ｒ」を形成することにより、空気溜Ｓ２に至までの空気流路Ｗ２が長くなり、採血初流除去容器ＢＡ´を反転（倒立）させたときに、空気溜Ｓ２に導入された血液を、毛管現象により血液溜Ｓ１方向へ吸い上げやすくなる。さらに「誘導壁面ＷＣ」を形成することにより、空気が「誘導壁面ＷＣ」に沿って、空気溜Ｓ２に入りやすくなる。
また上開放部Ｏ１も狭くなるので、空気溜Ｓ２に空気を閉じ込めやすくなる。
また反転（倒立）させたときに、入口２３付近に残る血液が少なく、血液のロスを少なくすることができる。
また空気溜Ｓ２の容積を相対的に大きくできるので、血液中への空気の混入をより確実に防止することができる。 [Usage example of blood collection initial flow removal container BD]
An example of a usage example method of the blood collection initial flow removal container BD of FIG. 6 will be described with reference to FIG.
(A) to (B): The primary blood is introduced from the inlet 23 into the blood reservoir S1 through the blood passage W1 and the lower opening O2 ′. The air in the blood reservoir S1 is introduced into the air reservoir S2 via the lower opening O2, the air passage W2, and the upper opening O1.
(C): When the introduction of the initial blood is further continued, the initial blood passes through the lower open portion O2, the air passage W2, the guide portion R, the upper open portion O1, and the guide wall surface WC into the air reservoir S2. Department introduced. (D) to (E): The blood collection initial flow removal container BA ′ is inverted (inverted), and a vacuum blood collection tube (not shown) is attached to the collection needle 25 of the vacuum blood collection tube holder 22 to collect the initial flow blood. To do.
When the back body 21 is inverted, the blood in the blood reservoir S1 enters the air reservoir S2 through the lower opening O2, the air passage W2, and the upper opening O1, and then the fluid in the blood reservoir S1 and the air reservoir S2. The pressure is substantially in equilibrium. In the state where blood is present in the lower part of the air reservoir S2, the air in the air reservoir S2 is confined in the air reservoir S2 without flowing backward in the direction of the blood reservoir S1 via the air passage W2.
Initially, as shown in (D), the primary blood is primarily introduced into the air reservoir S2, but gradually, as shown in (F), the guiding wall surface WC, the upper open portion O1, the guiding portion R, and the air passage W2. Then, it moves to the blood reservoir S1 through the lower opening O2, and is collected into a vacuum blood collection tube (not shown) through the collection needle 25. The air in the air reservoir S2 is completely sealed in the air reservoir S2, and moves to the blood reservoir S1 through the guide wall surface WC, the upper open portion O1, the guide portion R, the air passage W2, and the lower open portion O2. There is no.
In the blood collection initial flow removal container BD, when the “guide portion R” is formed, the air flow path W2 leading to the air reservoir S2 becomes long, and the blood collection initial flow removal container BA ′ is inverted (inverted). The blood introduced into the air reservoir S2 can be easily sucked in the direction of the blood reservoir S1 by capillary action. Furthermore, by forming the “guidance wall surface WC”, air easily enters the air reservoir S2 along the “guidance wall surface WC”.
Moreover, since the upper open part O1 is also narrowed, it becomes easy to confine air in the air reservoir S2.
Further, when inverted (inverted), there is little blood remaining near the inlet 23, and blood loss can be reduced.
Further, since the volume of the air reservoir S2 can be relatively increased, it is possible to more reliably prevent air from being mixed into the blood.

要するに、（Ａ）容器本体２１に初流血液の入口２３と初流血液の出口２４を形成し、容器本体２１内部に、第１仕切部Ｐ１と第２仕切部Ｐ２と第３仕切部Ｐ３を形成し、これにより容器本体２１内部を、血液溜Ｓ１と空気溜Ｓ２に区画するとともに、血液通路Ｗ１と空気通路Ｗ２を形成したものであって、（Ｂ）初流血液を空の容器本体２１に貯留するとき、初流血液は、入口２３、血液通路Ｗ１を経て、血液溜Ｓ１に貯留され、当該血液溜Ｓ１の空気は、空気溜Ｓ２へ収納され、（Ｃ）バック本体２１を倒立させたとき、血液溜Ｓ１の血液は、空気通路Ｗ２から空気溜Ｓ２内に侵入し、その後、血液溜Ｓ１と空気溜Ｓ２内の流体圧力が、実質的に平衡状態となり、前記空気溜Ｓ２に血液が存在する状態では、空気溜Ｓ２内の空気は血液溜Ｓ１方向へは逆流せず、空気溜Ｓ２内に閉じ込められるものであれば何でも良い。
「血液溜Ｓ１と空気溜Ｓ２内の流体圧力が、実質的に平衡状態」になるとは、血液溜Ｓ１と空気溜Ｓ２内の流体（血液、空気を含む）が、相互に血液溜Ｓ１と空気溜Ｓ２の間の出入りを停止した状態または出入りしにくくなった状態（血液溜Ｓ１と空気溜Ｓ内の流体圧力が実質的に同じ（等圧）になった状態または拮抗した状態）を意味する。 The blood collection initial flow removal container of the present invention is not limited to the form illustrated in FIGS. 1, 3, 4, and 6.
In short, (A) the primary blood inlet 23 and the primary blood outlet 24 are formed in the container body 21, and the first partition part P 1, the second partition part P 2, and the third partition part P 3 are provided inside the container body 21. In this way, the container body 21 is divided into a blood reservoir S1 and an air reservoir S2, and a blood passage W1 and an air passage W2 are formed. Is stored in the blood reservoir S1 through the inlet 23 and the blood passage W1, and the air in the blood reservoir S1 is stored in the air reservoir S2, and (C) the back body 21 is inverted. Then, the blood in the blood reservoir S1 enters the air reservoir S2 from the air passage W2, and then the fluid pressure in the blood reservoir S1 and the air reservoir S2 is substantially in an equilibrium state, and the blood reservoir S2 has blood. In the state where the air is present, the air in the air reservoir S2 is a blood reservoir. The one direction without reverse flow, may be any as far as it is confined within the air cavity S2.
“The fluid pressure in the blood reservoir S1 and the air reservoir S2 is substantially in equilibrium” means that the fluid (including blood and air) in the blood reservoir S1 and the air reservoir S2 is mutually in contact with the blood reservoir S1 and air. Means a state in which entry / exit between the reservoirs S2 is stopped or a state in which entry / exit becomes difficult (a state in which the fluid pressure in the blood reservoir S1 and the air reservoir S are substantially the same (equal pressure) or an antagonistic state). .

本発明は、容器の中に貯留した液体を、容器から抜き取る際に（抜き取る方向に関係なく）、空気が液体に混入しないようにしたい目的であれば、医療、工業を問わずその他の全ての分野に利用できる。
例えば以下の利用例が想定される。
［利用例１：輸液］
例えば患者に二種類以上の輸液剤（例えば輸液剤Ａ、輸液剤Ｂ）連続して投与する場合、輸液剤Ａ、輸液剤Ｂをそれぞれ容器ＡＢ、ＢＢに入れ、当該容器ＡＢ、ＢＢに輸液セットＡＳ、ＢＳを接続する。
容器ＡＢ中の輸液剤Ａが空になって、空気が輸液セットＡＳの点滴筒ＡＳＣより患者側へ入り込むと、容器ＢＢ中の輸液剤Ｂの点滴を行うときに、空気が血管に入り込む。これを防止するため、点滴終了を感知するセンサ器具等を、容器ＡＢ、ＢＢまたは輸液セットＡＳ、ＢＳ等に取り付けられている。
これらの容器ＡＢ、ＢＢの代わりに、本発明の液体容器Ｂ、ＢＡ、ＢＡ´、ＢＤを使用し、液体出口２４に輸液セットＡＳを接続し、図５または図７に例示した方法と同様に、液体容器Ｂ、ＢＡ、ＢＡ´、ＢＤから輸液剤Ａを輸液セットＡＳにとりだすようにすれば、空気が輸液セットＡＳに入り込むことはないので、点滴終了を感知するセンサ器具等を使用しなくても、点滴が可能となる。
［利用例２：空気を含まない薬剤（医療・一般産業用）の製造］
また、例えば、液体容器Ｂ、ＢＡ、ＢＡ´、ＢＤの中に薬剤を一時的貯留し、図５または図７に例示した方法と同様に、液体容器Ｂ、ＢＡ、ＢＡ´、ＢＤの液体出口から薬剤を、とりだして、他の容器に詰め替えれば、空気を含まない薬剤（空気を含まない薬剤入り容器）を製造することが可能である。 The present invention is not limited to any other medical or industrial use as long as it is intended to prevent air from being mixed into the liquid when the liquid stored in the container is extracted from the container (regardless of the direction of extraction).

For example, when two or more kinds of infusions (for example, infusion A and infusion B) are continuously administered to a patient, the infusion A and the infusion B are placed in containers AB and BB, respectively, and infusion sets are set in the containers AB and BB. Connect AS and BS.
When the infusion agent A in the container AB becomes empty and air enters the patient side from the infusion tube ASC of the infusion set AS, the air enters the blood vessel when the infusion agent B in the container BB is instilled. In order to prevent this, a sensor device or the like for detecting the end of infusion is attached to the containers AB and BB or the infusion sets AS and BS.
Instead of these containers AB and BB, the liquid containers B, BA, BA ′, and BD of the present invention are used, the infusion set AS is connected to the liquid outlet 24, and the method illustrated in FIG. 5 or FIG. If the infusion agent A is taken out from the liquid containers B, BA, BA ′, BD to the infusion set AS, air does not enter the infusion set AS, so that a sensor device that senses the end of infusion is not used. Even infusion is possible.
