Description

本発明は、血液分離器具に関し、特に、採取した血液をその場で、血球及び細胞成分と血漿又は血清に分離する血液分離器具に関するものである。   The present invention relates to a blood separation device, and more particularly to a blood separation device that separates collected blood into blood cells and cell components and plasma or serum in situ.

一般に、採血には、医師等一定の有資格者が注射器を用いて静脈から血液を採取する一般採血と、検査対象者本人が自分の手の指等に採血針を刺して血液を採取する自己採血とがある。   In general, blood sampling involves general blood collection, in which a doctor or other qualified person collects blood from a vein using a syringe, and the person to be inspected is self-collected by inserting a blood collection needle into his / her finger etc. There is blood sampling.

一般採血により採取した血液は、採取容器に密閉された状態で検査場所に搬送され、そこで遠心分離器により、血球及び細胞成分と血漿又は血清に分離された後、検査が行われる。また、自己採血により採取された血液は、濾紙に含浸され乾燥された状態で検査場所に搬送され、その検査場所にて濾紙を溶剤に溶解させ、分析が行われる。   Blood collected by general blood collection is transported to a test place in a state of being sealed in a collection container, where it is separated into blood cells and cell components and plasma or serum by a centrifuge, and then tested. Further, blood collected by self blood collection is transported to an inspection place in a state of being impregnated in a filter paper and dried, and the filter paper is dissolved in a solvent at the inspection place for analysis.

特開2006−322829号公報JP 2006-322829 A

しかしながら、上記した従来の一般採血の場合、採取した血液を遠心分離した後、上澄みの血球及び細胞成分をスポイトで吸い取り、血漿分析機用の特殊容器に移さなければならないので、血液を血球及び細胞成分と血漿又は血清に分離するのに手間が掛かりコスト高になり、また、特殊容器に移す際に、取り違う等の事故が起きる虞れがあった。   However, in the case of the above-described conventional general blood collection, the collected blood must be centrifuged, and the supernatant blood cells and cell components must be sucked with a dropper and transferred to a special container for a plasma analyzer. Separation of components into plasma or serum is time consuming and expensive, and there is a risk of accidents such as misplacement when transferred to special containers.

また、血液中の血球は時間の経過と共に溶血し、血液の常温放置での精度保証期間はせいぜい1日程度であるので、それ以後に検査を行った場合にはナトリウム、カリウム、クロム等の電解質物質の測定数値に悪影響を及ぼしたり、GOT、GPT等の酵素系の数値の測定ができなくなったりし、診療、診断等の指針となるような検査数値が期待できなくなるといった問題が生じていた。   In addition, blood cells in the blood are hemolyzed over time, and the accuracy guarantee period when the blood is left at room temperature is at most about one day. Therefore, when the test is conducted after that, electrolytes such as sodium, potassium, chromium, etc. There have been problems such as adversely affecting the measured values of substances, making it impossible to measure numerical values of enzymes such as GOT and GPT, and making it impossible to expect test values that can serve as guidelines for medical treatment and diagnosis.

また、遠心分離器により血液を分離させ、所定項目の検査を行うためには、1回に5〜10mL程度の採血量が必要とされていた。したがって、検査対象者本人で採血することは困難であり、医師等一定の有資格者が採血することになるので、検査対象者が病院等に行くか、或いは有資格者が検査対象者の居所に出向いたりする必要があり、採血に手間が掛かっていた。   In addition, in order to separate blood with a centrifuge and perform a test on a predetermined item, a blood collection amount of about 5 to 10 mL is required at a time. Therefore, it is difficult for the person to be tested to collect blood, and a certain qualified person such as a doctor will collect blood, so the person to be examined goes to a hospital or the like, or the qualified person is the residence of the person to be examined. It was necessary to go to the hospital, and it took time and effort to collect blood.

一方、上記した従来の自己採血は、血液を濾紙に含浸させ乾燥させた後に溶剤に溶解させる工程を必要とするため、斯かる工程を経ても検査数値に影響を与えるおそれのない特定の検査項目に関してのみ有効であり、これらの検査項目以外での実施は不可能であった。   On the other hand, the above-mentioned conventional self-collecting blood requires a process of impregnating blood into filter paper and drying it, and then dissolving it in a solvent. It was effective only with respect to the above, and it was impossible to carry out other than these inspection items.

本発明は上記事情を鑑みてなされたものであり、血液検査のコスト低減化や血液の保存性及び検査精度の向上を図ることができると共に、採血作業及び血液検査作業の簡素化を図ることのできる血液分離器具を提供することを目的とするものである。   The present invention has been made in view of the above circumstances, and can reduce the cost of blood tests, improve blood storage stability and test accuracy, and can simplify blood collection work and blood test work.

The blood separation instrument 10 includes a blood collection component 11 for collecting blood and an additive disposed above the blood collection component 11. The pressure component 12, the holding component 13 that holds the blood collection component 11 and the pressure component 12, and the accommodating component 15 that accommodates the diluent 14 therein.

図2〜図4に示されているように、採血部品11は、筒状を成し、その外形は上端部16が円形を成し、下方に向かうに従って次第に扁平形状となるように形成されている。採血部品11の中空部17は所定の容積(例えば、約65μリットル)を有しており、互いに対向する複数対(図示では二対)の突起部18により複数(図示では3個)の細長空間19a,19b,19cに分割されている。各細長空間19a,19b,19cは互いに連通しており、図5に良く示されているように、各細長空間19a,19b,19cを取り囲む周壁内面には凹凸部20が形成されており、この凹凸部20により毛細管現象を促進することができる。また、採血部品11の下端部には段差部49が形成されている。   As shown in FIGS. 2 to 4, the blood collection component 11 has a cylindrical shape, and the outer shape thereof is formed such that the upper end portion 16 has a circular shape and gradually becomes flat as it goes downward. Yes. The hollow part 17 of the blood collection component 11 has a predetermined volume (for example, about 65 μl), and a plurality (three in the figure) of elongated spaces are formed by a plurality of pairs (two in the figure) projecting parts 18 facing each other. It is divided into 19a, 19b and 19c. The elongated spaces 19a, 19b, and 19c communicate with each other, and as shown in FIG. 5, an uneven portion 20 is formed on the inner surface of the peripheral wall that surrounds the elongated spaces 19a, 19b, and 19c. Capillarity can be promoted by the uneven portion 20. Further, a stepped portion 49 is formed at the lower end of the blood collection component 11.

また、採血部品11の下端と収容部品15内の希釈液14の表面との間には表面張力が発生する程度の僅かな隙間51(図1参照)が形成されており、この隙間51は2〜5mm程度であるのが好ましい。   Further, a slight gap 51 (see FIG. 1) is generated between the lower end of the blood collection component 11 and the surface of the diluent 14 in the housing component 15 so that surface tension is generated. It is preferably about ˜5 mm.

図6及び図7に示されているように、加圧部品12は、押圧操作するためのプッシュボタン部21と、プッシュボタン部21の下端部に突設された軸部22とを備えている。プッシュボタン部21は、平面形状が円形となるように複数の板状部材23を櫛歯状に接続することにより形成され、上端部は半球状に形成され、下端面24は平坦に形成されている。また、軸部22は、十字状の平断面を有し、下端には平坦な加圧面25が形成され、加圧面25の直上部分に溝部26が形成されている。   As shown in FIGS. 6 and 7, the pressurizing component 12 includes a push button portion 21 for performing a pressing operation, and a shaft portion 22 protruding from the lower end portion of the push button portion 21. . The push button portion 21 is formed by connecting a plurality of plate-like members 23 in a comb shape so that the planar shape is circular, the upper end portion is formed in a hemispherical shape, and the lower end surface 24 is formed flat. Yes. Further, the shaft portion 22 has a cross-shaped flat cross section, a flat pressure surface 25 is formed at the lower end, and a groove portion 26 is formed immediately above the pressure surface 25.

図8〜図10に示されているように、保持部品13は、凹凸の外面を有する略円筒形状の上側部分27と、鍔部28を隔てて上側部分27の下方に形成される略円筒形状の中間部分29と、中間部分29の下方に連続して形成される円筒形状の下端部分30とを備えて構成されている。そして、保持部品13の上側部分27に加圧部品12のプッシュボタン部21を収容し、中間部分29に加圧部品の軸部22を保持させ、下端部分30に採血部品11の上端部16を保持させることにより、採血器具50が組み付けられるようになっている。   As shown in FIGS. 8 to 10, the holding component 13 includes a substantially cylindrical upper portion 27 having an uneven outer surface, and a substantially cylindrical shape formed below the upper portion 27 with the flange portion 28 therebetween. Intermediate portion 29 and a cylindrical lower end portion 30 formed continuously below the intermediate portion 29. Then, the push button portion 21 of the pressurizing component 12 is accommodated in the upper portion 27 of the holding component 13, the shaft portion 22 of the pressurizing component is held in the intermediate portion 29, and the upper end portion 16 of the blood sampling component 11 is held in the lower end portion 30. By holding it, the blood collection device 50 can be assembled.

鍔部28は、左右両側が側方に突出する外鍔部31と、内側に円形の通孔32を有する内鍔部33とにより構成されており、通孔32は、その内径が、プッシュボタン部21の下端面24の外径より小さく、軸部22の最大外径より大きくなるように形成されている。   The flange portion 28 includes an outer flange portion 31 that protrudes laterally on both the left and right sides, and an inner flange portion 33 having a circular through hole 32 on the inner side. The through hole 32 has a push button that has an inner diameter. It is formed so as to be smaller than the outer diameter of the lower end surface 24 of the portion 21 and larger than the maximum outer diameter of the shaft portion 22.

中間部分29は、通孔32の内径と略同一の内径を有し、中間部分29の周壁34の前後面にはそれぞれ矩形状の開口35が形成され、開口35の下方の周壁内面には中心角が90度を成すように4個の補強リブ36が突設されている。   The intermediate portion 29 has an inner diameter substantially the same as the inner diameter of the through hole 32, and rectangular openings 35 are formed on the front and rear surfaces of the peripheral wall 34 of the intermediate portion 29, respectively. Four reinforcing ribs 36 are projected so that the angle forms 90 degrees.

図11〜図13に示されているように、保持部品13の中間部分の開口35には、ロック部品37が挿着されている。このロック部品37は、各開口35を閉塞する周壁部38と、周壁部38の上端部の前後端部同士をそれぞれ連結する上端連結部39と、周壁部38の中央部同士を連結する中央連結部40と、周壁部38の各下端部から互いに近接する方向に延出して対峙する係合部41とにより構成されている。   As shown in FIGS. 11 to 13, a lock part 37 is inserted into the opening 35 in the intermediate part of the holding part 13. The lock component 37 includes a peripheral wall portion 38 that closes each opening 35, an upper end connection portion 39 that connects the front and rear end portions of the upper end portion of the peripheral wall portion 38, and a central connection that connects the central portions of the peripheral wall portion 38 to each other. It is comprised by the part 40 and the engaging part 41 which extends in the direction which mutually adjoins from each lower end part of the surrounding wall part 38, and opposes it.

周壁部38の外面の上端部には解除操作部42がそれぞれ前後方向に突設されており、この解除操作部42の下部には傾斜面から成るガイド部43が形成されている。上端連結部39の中央には伸縮部44が形成され、伸縮部44は他の部分より細幅の部材を正面視でへの字状を成すように屈曲させることにより形成されている。また、中央連結部40の中央には円形の通孔45が形成されており、この通孔45は、内径が軸部22の最大外径より大きくなるように形成されている。さらに、対峙する係合部41の間には略楕円形状の空間46が形成されており、この空間46の短径は通孔45の内径より僅かに短く設定されている。これにより、採血器具50の組み付け時には、この係合部41が軸部22の溝部26を両側から挟持することにより軸部22に係合し、加圧部品12の動きが拘束されるようになっている。   A release operation part 42 projects from the upper end of the outer surface of the peripheral wall part 38 in the front-rear direction, and a guide part 43 having an inclined surface is formed below the release operation part 42. An expansion / contraction part 44 is formed at the center of the upper end connecting part 39, and the expansion / contraction part 44 is formed by bending a member having a narrower width than the other part so as to form a U-shape when viewed from the front. Further, a circular through hole 45 is formed at the center of the central connecting portion 40, and the through hole 45 is formed so that the inner diameter is larger than the maximum outer diameter of the shaft portion 22. Further, a substantially elliptical space 46 is formed between the engaging portions 41 facing each other, and the short diameter of the space 46 is set slightly shorter than the inner diameter of the through hole 45. Thereby, when the blood collection device 50 is assembled, the engaging portion 41 engages with the shaft portion 22 by sandwiching the groove portion 26 of the shaft portion 22 from both sides, and the movement of the pressurizing component 12 is restricted. ing.

収容部品15は、上端部47に開口部48を備え、この開口部48の内径は保持部品13の中間部分29の外径に略等しく、上端部47に保持部品13の中間部分29が挿着可能となっている。また、上端部47の外面は螺刻され、この上端部47にキャップ(図示省略)が螺嵌可能となっている。   The housing component 15 has an opening 48 at the upper end 47, the inner diameter of the opening 48 is substantially equal to the outer diameter of the intermediate portion 29 of the holding component 13, and the intermediate portion 29 of the holding component 13 is inserted into the upper end 47. It is possible. Further, the outer surface of the upper end 47 is threaded, and a cap (not shown) can be screwed onto the upper end 47.

次に、上記した構成を備えた血液分離器具10の使用方法について説明する。   Next, the usage method of the blood separation instrument 10 provided with the above-mentioned structure is demonstrated.

先ず、検査対象者は、自分の手の指等に採血針(図示省略)を突き刺し、出血させ、採血部品11の下端をその出血箇所に接触させる。そうすると、毛細管現象により、血液が中空部17内に、微量(例えば、約65μリットル)採取される。この時、採血部品11の下端部に段差部49が形成されていると共に、中空部17内が互いに連通する細長空間19a,19b,19cに分割され、しかも、各細長空間19a,19b,19cを取り囲む周壁内面に凹凸部20が形成されているため、中空部17内への血液の採取作業を容易且つ確実に行うことができる。   First, the person to be inspected pierces a finger or the like of his / her hand with a blood collection needle (not shown), causes bleeding, and brings the lower end of the blood collection component 11 into contact with the bleeding site. Then, a very small amount of blood (for example, about 65 μl) is collected in the hollow portion 17 by capillary action. At this time, a stepped portion 49 is formed at the lower end of the blood collection component 11, and the hollow portion 17 is divided into elongated spaces 19a, 19b, and 19c that communicate with each other, and the elongated spaces 19a, 19b, and 19c are divided. Since the concavo-convex portion 20 is formed on the inner surface of the surrounding peripheral wall, the blood sampling operation into the hollow portion 17 can be easily and reliably performed.

次いで、図1に示すように、採血部品11に血液を採取した採血器具50を、上端部47の開口部48から収容部品15内に挿着すると、ロック部品37の解除操作部42が収容部品15の上端部47の内面に押圧され、伸縮部44が収縮して上端連結部39が中央連結部40を支点に内側方向に移動する。   Next, as shown in FIG. 1, when the blood collection device 50 that has collected blood in the blood collection component 11 is inserted into the accommodation component 15 from the opening 48 of the upper end 47, the release operation portion 42 of the lock component 37 is accommodated in the accommodation component. 15 is pressed against the inner surface of the upper end portion 47, the telescopic portion 44 contracts, and the upper end connecting portion 39 moves inward with the central connecting portion 40 as a fulcrum.

この上端連結部39の動きに伴い、係合部41は反対に中央連結部40を支点に互いに離間する方向(すなわち、外側方向)に移動し、係合部41と軸部22の溝部26との係合状態が解除される。そこで、この時、プッシュボタン部21を下方に押圧すると、加圧部品12は保持部品13内で押し下げられ、加圧面25が採血部品11の上方のエアーを加圧するため、中空部17内の血液は採血部品11の下端から希釈液14内に滴下される。また、この時、採血部品11の下端と収容部品15内の希釈液14の表面との間に僅かな隙間51が形成されているため、希釈液14の表面張力により、採血部品11から安定した量の血液を簡単に取り出すことができる。   As the upper end connecting portion 39 moves, the engaging portion 41 moves in the direction away from each other with the central connecting portion 40 as a fulcrum (that is, the outward direction), and the engaging portion 41 and the groove portion 26 of the shaft portion 22 The engagement state is released. Therefore, at this time, when the push button portion 21 is pressed downward, the pressurizing component 12 is pushed down in the holding component 13 and the pressurizing surface 25 pressurizes the air above the blood collecting component 11, so that the blood in the hollow portion 17. Is dripped into the diluent 14 from the lower end of the blood collection part 11. At this time, since a slight gap 51 is formed between the lower end of the blood collection component 11 and the surface of the diluent 14 in the housing component 15, the surface tension of the dilution solution 14 stabilizes the blood collection component 11. An amount of blood can be easily removed.

この場合、毛細管現象で血液を吸引可能な筒状の採血部品11を使用しているため、この希釈液14中では、容易に血液成分を分散させることが可能となり、血液は血球及び細胞成分と血漿又は血清に容易に分離される。また、解除操作部42の下部に傾斜面からなるガイド部43が形成されており、しかも上端連結部39の中央に伸縮部44が形成されているため、収容部品15に対する採血器具50の挿着、及び係合部41と軸部の溝部26との係合状態の解除を円滑且つ確実に行うことができる。   In this case, since the cylindrical blood collection component 11 capable of sucking blood by capillary action is used, the blood component can be easily dispersed in the diluted solution 14, and the blood is separated from blood cells and cell components. Easily separated into plasma or serum. In addition, a guide portion 43 having an inclined surface is formed in the lower portion of the release operation portion 42, and an expansion / contraction portion 44 is formed in the center of the upper end connecting portion 39, so that the blood collection device 50 is inserted into the housing component 15. And the engagement state of the engaging part 41 and the groove part 26 of the shaft part can be smoothly and reliably released.

その後、使用済みの採血器具50を収容部品15から引き抜き、血液を収容した収容部品15の上端部47に前記キャップを螺嵌して検査場所まで搬送し、所定項目の検査を行う。   Thereafter, the used blood collection device 50 is pulled out from the housing component 15, and the cap is screwed onto the upper end 47 of the housing component 15 housing the blood, which is then transported to the inspection location, where predetermined items are inspected.

このように本発明の実施の形態に係る血液分離器具10によれば、採血後直ぐにその場で血液を血球及び細胞成分と血漿又は血清とに分離させ、希釈液に混入させた状態で検査場所に搬送しているので、搬送中の溶血、血液の凝固等を防止することができる。したがって、血液の保存性がよく、検査精度の向上を図ることができる。また、採取した血液を1週間程度は常温で保存可能であり、搬送を迅速に行ったり、採血場所と検査場所の地域性を考慮したりする等の配慮が不要となり、作業の自由度を向上させることが可能となる。さらに、血液の分離に遠心分離器を使用しないので採血量が数滴で済み、自己採血により、従来の一般採血と同程度の項目について検査することができる。   As described above, according to the blood separation instrument 10 according to the embodiment of the present invention, immediately after blood collection, the blood is separated into blood cells and cell components and plasma or serum on the spot, and mixed with the diluent. Therefore, hemolysis, blood coagulation, and the like during transportation can be prevented. Therefore, the preservation of blood is good and the test accuracy can be improved. In addition, the collected blood can be stored at room temperature for about a week, eliminating the need for quick transportation and consideration of the regional characteristics of the blood collection location and the test location, improving the degree of freedom of work. It becomes possible to make it. Furthermore, since a centrifuge is not used for blood separation, only a few drops of blood are collected, and items comparable to those of conventional general blood can be inspected by self-collection.

なお、上記実施の形態では、本発明を自己採血で使用する場合について説明したが、一般採血においても使用可能であることは言う迄もない。   In the above embodiment, the case where the present invention is used for self-collection has been described, but it goes without saying that the present invention can also be used for general blood collection.
