Description

本発明は血液定量採取キットに関する。   The present invention relates to a blood quantitative collection kit.

従来の血液採取ピペットは細管と可撓性キャップが連結してなる。細管の端から異なる距離の２ヶ所に目印が付してある。従来の血液採取ピペットを手で持って、細管の端を血液の中に浸漬する。すると、毛細管現象によって血液が徐々に細管の中に入ってゆく。そして、時間が経過し、２つの目印の間まで血液が到達した時に、細管の端を血液の外へと移して、血液の採取を終了する。その後に、可撓性キャップを押して、細管の中に溜まっている血液を吐出させる。   A conventional blood sampling pipette is formed by connecting a thin tube and a flexible cap. Marks are attached at two different distances from the end of the capillary tube. Hold a conventional blood collection pipette by hand and immerse the end of the capillary tube into the blood. Then, blood gradually enters the tubule by capillary action. When time passes and blood reaches between the two marks, the end of the capillary tube is moved out of the blood, and the blood collection is finished. Thereafter, the flexible cap is pushed to discharge the blood accumulated in the narrow tube.

採血対象者は針などによって指先等に傷を付けて、その傷から出てきた血液に従来の血液採取ピペットの細管の端を浸漬して、血液を採取する。しかし、採血対象者によっては時間あたりの出血量が少ない場合があり、その場合には、血液の中へ細管の端を浸漬するのが困難であり、所定量を採取するまでに時間がかかる。あるいは、所定量まで至らずに採取した血液を途中で吐出してしまい、指などを吐出した血液で汚してしまうという問題がある。   A blood collection target scratches a fingertip or the like with a needle or the like, and collects blood by immersing the end of a capillary tube of a conventional blood sampling pipette into the blood that comes out of the wound. However, depending on the blood collection subject, the amount of bleeding per hour may be small. In this case, it is difficult to immerse the end of the thin tube in the blood, and it takes time to collect the predetermined amount. Alternatively, there is a problem that blood collected without reaching a predetermined amount is discharged halfway, and the finger or the like is contaminated with the discharged blood.

また、採取の途中で空気が混入してしまい採取量が不足し、その後の正確な血液検査等ができないという問題が生じやすい。そのため、吐出と採取とも何度も繰り返さなければならず問題である。   In addition, air is likely to be mixed in during collection, resulting in a shortage of collection, and subsequent problems such as inaccurate blood tests are likely to occur. For this reason, both discharge and collection must be repeated many times.

そこで、本発明の目的は、微量の血液を正確かつ容易に採取できるとともに、気泡が混入しにくい、比較的安価な血液定量採取キットを提供することである。   Accordingly, an object of the present invention is to provide a relatively inexpensive blood quantitative collection kit that can collect a small amount of blood accurately and easily and is less likely to contain bubbles.

上記目的は、請求項１に記載の本発明に係る血液定量採取キット、すなわち、平板状のベース部とキャピラリー部とを有し、それぞれ分離可能な血液定量採取キットであって、ベース部の上面には、所定容積のくぼみである血液溜まり部が形成され、圧縮可能なキャップ部であって、空気孔を有するキャップ部と毛細直管部とが接合されてキャピラリー部が構成され、キャピラリー部の毛細直管部の端部が血管溜まり部の底部近くに位置している血液定量採取キットによって、達成される。   An object of the present invention is to provide a blood quantitative collection kit according to the present invention as set forth in claim 1, that is, a blood quantitative collection kit having a flat base portion and a capillary portion, and each separable blood quantitative kit. The blood reservoir part, which is a hollow with a predetermined volume, is formed and is a compressible cap part. The cap part having an air hole and the capillary tube part are joined to form a capillary part. This is achieved by a blood quantitative collection kit in which the end of the capillary tube is located near the bottom of the blood vessel reservoir.

本発明の好ましい実施態様においては、請求項２に記載のように、血液採取中には剥離可能なシールまたは取り外し可能な蓋によって空気孔が塞がれており、血液採取後には、シールが剥離され、あるいは、蓋が取り外され、空気孔が開放されて、血液溜まりに一時貯えられている血液がキャピラリーの中へ収容される。   In a preferred embodiment of the present invention, as described in claim 2, the air hole is closed by a peelable seal or a removable lid during blood collection, and after the blood collection, the seal is peeled off. Alternatively, the lid is removed, the air hole is opened, and the blood temporarily stored in the blood reservoir is accommodated in the capillary.

また、本発明の他の好ましい実施態様においては請求項３に記載のように、血液溜まり部の容積が５０μl、８０μlあるいは１００μlである。   In another preferred embodiment of the present invention, as described in claim 3, the volume of the blood reservoir is 50 μl, 80 μl or 100 μl.

本発明のさらに他の好ましい実施態様においては、請求項４に記載のように、ベース部が透明である。   In still another preferred embodiment of the present invention, as described in claim 4, the base portion is transparent.

本発明の別の好ましい実施態様においては、請求項５に記載のように、キャピラリー部が透明である。   In another preferred embodiment of the present invention, as described in claim 5, the capillary portion is transparent.

本発明に係る血液定量採取キットは、平板状のベース部とキャピラリー部とを有し、それぞれ分離可能な血液定量採取キットであって、ベース部の上面には、所定容積のくぼみである血液溜まり部が形成され、圧縮可能なキャップ部であって、空気孔を有するキャップ部と毛細直管部とが接合されてキャピラリー部が構成され、キャピラリー部の毛細直管部の端部が血管溜まり部の底部近くに位置しているので、空気孔を塞いだ状態で、血液溜まり部の中へ血液を注入し、所定量が溜まった時に注入を停止し、その後に空気孔を開放すると血液溜まり部に溜まっている所定量の血液が毛細管現象で毛細直管部の中へ移動する。よって、両手を自由に使える状態で正確な量の血液を容易に採取することができるという効果が得られる。   A blood quantitative collection kit according to the present invention has a flat base portion and a capillary portion, and is a separable blood quantitative collection kit, wherein a blood reservoir that is a hollow of a predetermined volume is formed on the upper surface of the base portion. The cap portion is formed and is a compressible cap portion, and a cap portion having an air hole and a capillary tube portion are joined to form a capillary portion, and an end portion of the capillary tube portion of the capillary portion is a blood vessel reservoir portion Since the air hole is closed, blood is injected into the blood reservoir, the injection is stopped when a predetermined amount has accumulated, and then the air reservoir is opened. A predetermined amount of blood accumulated in the tube moves into the capillary tube portion by capillary action. Therefore, it is possible to easily collect an accurate amount of blood while using both hands freely.

また、血液溜まり部の低部近くに毛細直管部の端部が位置しているので、採取した血液の中に空気が混入しにくいという効果が得られる。   In addition, since the end of the capillary tube portion is located near the lower portion of the blood reservoir, an effect that air is less likely to be mixed into the collected blood is obtained.

以下、本発明の血液定量採取キットの実施形態について、添付図面を参照して、詳細に説明する。   Hereinafter, embodiments of the blood quantitative collection kit of the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明の血液定量採取キットの斜視図であり、図２は本発明の血液定量採取キットの使用方法を示す説明図である。   FIG. 1 is a perspective view of a blood quantitative collection kit of the present invention, and FIG. 2 is an explanatory diagram showing a method for using the blood quantitative collection kit of the present invention.

ベース部１はほぼ平板状であり、上面１ａから所定容積、例えば５０μlのくぼみが形成され、血液溜まり部１ｂとなっている。ベース部１の１つの側面１ｃから直管孔１ｄが血液溜まり部１ｂの低部近くまで穿ってある。ベース部１は透明であるのが好ましいが、材質は問わない。   The base portion 1 has a substantially flat plate shape, and a recess having a predetermined volume, for example, 50 μl, is formed from the upper surface 1a to form a blood pool portion 1b. A straight tube hole 1d is bored from one side surface 1c of the base portion 1 to near the lower portion of the blood reservoir 1b. The base portion 1 is preferably transparent, but the material is not limited.

キャピラリー部３は毛細直管部３ａとキャップ部３ｂとが接合されてなる。キャップ部３ｂは圧縮可能であり、空気孔３ｄが形成されている。空気孔３ａにはシール３ｅが剥離可能に貼り付けられている。キャピラリー部３は透明であるのが好ましい。   The capillary portion 3 is formed by joining a capillary straight tube portion 3a and a cap portion 3b. The cap part 3b is compressible and has an air hole 3d. A seal 3e is detachably attached to the air hole 3a. The capillary part 3 is preferably transparent.

図２（１）は、初めの状態を図示したものであり、キャピラリー部３の毛細直管部３ａは、ベース部１の直管孔１ｄの中へ挿入されており、毛細直管部３ａの端３ｆはベース部１の血管溜まり部１ｂの低部近くに位置している。次に、血液を血液溜まり部１ｂの上方から注入する。   FIG. 2 (1) illustrates the initial state, and the capillary straight tube portion 3a of the capillary portion 3 is inserted into the straight tube hole 1d of the base portion 1, and the capillary straight tube portion 3a The end 3 f is located near the lower part of the blood vessel reservoir 1 b of the base 1. Next, blood is injected from above the blood reservoir 1b.
