Description

本発明は、糖尿病患者などの採血に使用する採血具に関する。   The present invention relates to a blood collection tool used for blood collection of a diabetic patient or the like.

従来の採血具として、軸方向にストレートな筒状本体の先端部から毛細管現象を利用して血液を吸収するものが知られている(例えば、特許文献1,2参照)。また、毛細管現象を利用して血液を吸収する筒状本体を高分子材料から製作し、かつ、筒状本体の内面を親水性に処理し、また筒状本体内の所定の位置には吸引した血液量を所定の位置で止めるために液状封止用樹脂を配置し、この液状封止用樹脂の挿入を容易にするために筒状本体の吸引側先端部には外側に向かうに従って広がるテーパー面状の端部加工を施したものが知られている(例えば、特許文献3参照)。   As a conventional blood collection tool, one that absorbs blood from the distal end portion of a cylindrical main body that is straight in the axial direction using a capillary phenomenon is known (for example, see Patent Documents 1 and 2). In addition, a cylindrical body that absorbs blood using capillary action is manufactured from a polymer material, and the inner surface of the cylindrical body is treated to be hydrophilic, and sucked to a predetermined position in the cylindrical body. In order to stop the blood volume at a predetermined position, a liquid sealing resin is arranged, and in order to facilitate the insertion of the liquid sealing resin, a tapered surface that widens toward the outside on the suction side tip of the cylindrical body What performed the shape edge part process is known (for example, refer patent document 3).

しかしながら、従来の採血具は、血液の吸い上げ効果を高めるために毛細管現象を利用しようとしているが、その効果は十分なものではなかった。   However, the conventional blood collection device attempts to utilize the capillary phenomenon in order to enhance the blood sucking effect, but the effect is not sufficient.

本発明の目的は、血液の吸い上げ効果を高めた採血具を提供することにある。   An object of the present invention is to provide a blood collection tool with improved blood sucking effect.

本発明は上記目的を達成するために、筒状本体の吸い上げ側先端部に透明または半透明のプラスチック樹脂製の毛細管吸引筒部を形成し、前記毛細管吸引筒部による毛細管現象を利用して血液を吸い上げる採血具において、前記毛細管吸引筒部は、0.5〜5%のボロンを含有した前記プラスチック樹脂で形成したことを特徴とする。   In order to achieve the above object, the present invention forms a capillary suction cylinder made of a transparent or translucent plastic resin at the suction side tip of the cylindrical body, and utilizes the capillary phenomenon by the capillary suction cylinder to make blood flow In the blood collecting tool for sucking up blood, the capillary suction tube portion is formed of the plastic resin containing 0.5 to 5% boron.

上記構成によれば、プラスチック樹脂に0.5〜5%のボロンを混合して製作しているため、少なくとも毛細管吸引筒部を透明もしくは半透明としながら、優れた親水性を生かして血液の吸い上げ効果を高めることができる。またボロンの含有量を制限することによって、透明性を保持することができるので、目視による採血状況などの確認も容易に行うことができる。   According to the above configuration, since 0.5-5% boron is mixed with plastic resin, blood is drawn up by making use of excellent hydrophilicity while at least making the capillary suction tube portion transparent or translucent. The effect can be enhanced. In addition, since the transparency can be maintained by limiting the boron content, it is possible to easily check the blood collection status by visual observation.

また本発明は、上述の構成に加えて、ボロンの含有量を1〜2%としたことを特徴とする。   In addition to the above-described structure, the present invention is characterized in that the boron content is 1 to 2%.

上記構成によれば、ボロンの含有量をふさわしい範囲で、かつ少なく抑えることによって毛細管吸引筒部の透明性を保持しつつ、優れた親水性を生かして血液の吸い上げ効果を高めることができる。   According to the above configuration, it is possible to enhance the blood sucking effect by utilizing the excellent hydrophilicity while maintaining the transparency of the capillary suction tube portion by suppressing the boron content within a suitable range and by reducing it.

本発明による採血具によれば、少なくとも毛細管吸引筒部は、プラスチック樹脂に0.5〜5%のボロンを混合して製作しているため、透明もしくは半透明の状態を保ちながら、優れた親水性を生かして血液の吸い上げ効果を高めることができる。またボロンの含有量を制限することによって、透明性を保持することができるので、目視による採血状況などの確認も容易に行うことができる。   According to the blood collection device of the present invention, at least the capillary suction tube portion is manufactured by mixing 0.5 to 5% boron in a plastic resin, so that excellent hydrophilicity is maintained while maintaining a transparent or translucent state. The effect of sucking blood can be enhanced by taking advantage of its nature. In addition, since the transparency can be maintained by limiting the boron content, it is possible to easily check the blood collection status by visual observation.

本発明の一実施の形態による採血具の側面図である。It is a side view of the blood collection tool by one embodiment of the present invention. 図1に示した採血具の要部を拡大した断面図である。It is sectional drawing to which the principal part of the blood collection tool shown in FIG. 1 was expanded.

以下、本発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1は、本発明の一実施例による採血具を示す平面図である。   FIG. 1 is a plan view showing a blood collection device according to one embodiment of the present invention.

採血具全体は、患者の血液に接触させて毛細管現象を利用して吸い上げる毛細管吸引筒部1と、その後方に設けた中間筒部2と、図示しない分析装置側と接続する接続筒部3とを有し、詳細を後述するように軸方向の中心部には連続した空部が形成されている。この採血具は、少なくとも毛細管吸引筒部1、もしくは筒状部の全体をポリプロピレン樹脂、ABS樹脂、ポリカーボネート樹脂などのプラスチック樹脂に、0.5〜5%、望ましくは1〜2%のボロンを混合して透明体もしくは半透明体として構成されている。   The entire blood collection tool is brought into contact with the patient's blood and sucked up by utilizing the capillary phenomenon, a capillary suction cylinder part 1, an intermediate cylinder part 2 provided at the rear thereof, and a connection cylinder part 3 connected to the analyzer (not shown). As will be described in detail later, a continuous empty portion is formed in the central portion in the axial direction. In this blood collection tool, at least the capillary suction tube portion 1 or the entire tubular portion is mixed with a plastic resin such as polypropylene resin, ABS resin, polycarbonate resin, or the like in an amount of 0.5 to 5%, preferably 1 to 2%. Thus, it is configured as a transparent body or a translucent body.

少なくとも毛細管吸引筒部は、プラスチック樹脂に0.5〜5%のボロンを混合して製作しているため、透明もしくは半透明の状態を保ちながら、優れた親水性を生かして血液の吸い上げ効果を高めることができる。またボロンの含有量を制限することによって、透明性を保持することができるので、後述するように目視による採血状況などの確認も容易に行うことができる。   At least the capillary tube is made by mixing 0.5 to 5% boron with plastic resin, so that it can absorb blood with excellent hydrophilicity while maintaining a transparent or translucent state. Can be increased. In addition, since the transparency can be maintained by limiting the boron content, it is possible to easily confirm the state of blood sampling visually as described later.

上述した毛細管吸引筒部1は、全体的な外観は先細形状であるが、軸方向の中心部には中間筒部2側に向かって延びた比較的に径の小さな吸引採血保持孔4が形成されている。この吸引採血保持孔4の径と軸方向長は、採血具を使用しての採血量単位を確保できるように決定されている。   The capillary suction tube portion 1 described above has a tapered shape as a whole, but a suction blood collection holding hole 4 having a relatively small diameter extending toward the intermediate tube portion 2 is formed in the central portion in the axial direction. Has been. The diameter and axial length of the suction blood collection holding hole 4 are determined so as to secure a blood collection unit using a blood collection tool.

また上述した中間筒部2も全体として円筒状であり、毛細管吸引筒部1側の端部を吸引採血保持孔5に連通して開口面積を急激に大きくした中空部5が形成されている。   Further, the above-described intermediate tube portion 2 is also cylindrical as a whole, and a hollow portion 5 is formed in which the end on the capillary suction tube portion 1 side communicates with the suction blood collection holding hole 5 and the opening area is rapidly increased.

さらに接続筒部3は、図示しない分析装置側の接続部に対応して接続可能な外観構造と、吸引採血保持孔4および中間室5に連通して分析装置へと導くための孔が形成されている。   Further, the connecting tube portion 3 is formed with an external structure that can be connected corresponding to a connecting portion on the analyzer side (not shown), and a hole that communicates with the suction blood collection holding hole 4 and the intermediate chamber 5 and leads to the analyzer. ing.

図2は、図1に示した採血具の先端部の拡大断面図である。   2 is an enlarged cross-sectional view of the distal end portion of the blood collection tool shown in FIG.

毛細管吸引筒部1に形成した吸引採血保持孔4は、十分に小さな径とされているため、左方の吸い上げ先端部を血液に接触すると、毛細管現象によって血液を吸い上げることができる。しかし、毛細管吸引筒部1の具体的な構成は、上述のものに限定しないが、毛細管現象を利用して採血時の血液を毛細管吸引筒部1から中間筒部2側へと吸い上げる構成のものを採用することができる。   Since the suction blood collection holding hole 4 formed in the capillary suction tube portion 1 has a sufficiently small diameter, blood can be sucked up by capillary action when the left suction tip is brought into contact with blood. However, the specific configuration of the capillary suction tube portion 1 is not limited to that described above, but is configured to suck blood from the capillary suction tube portion 1 toward the intermediate tube portion 2 using the capillary phenomenon. Can be adopted.

このような毛細管現象を利用した毛細管吸引筒部1を使用して、しかも、毛細管吸引筒部1の形成に際しては、上述したようにプラスチック樹脂に、0.5〜5%のボロンを混合して透明体もしくは半透明体としている。このため、優れた親水性を生かして毛細管現象を利用することができるようになり、吸い上げ効果が大きく改善される。ボロンの含有量を多くすると、透明性が損なわれてしまうが、0.5〜5%、望ましくは1〜2%の含有量とすることによって、採血状況を外部からの目視によって確認できるような透明度を確保することができる。   Using the capillary suction cylinder portion 1 utilizing such capillary phenomenon, and when forming the capillary suction cylinder portion 1, as described above, 0.5 to 5% boron is mixed into the plastic resin. Transparent or semi-transparent. For this reason, it becomes possible to utilize the capillary phenomenon by making use of excellent hydrophilicity, and the sucking effect is greatly improved. If the content of boron is increased, the transparency is impaired, but by setting the content to 0.5 to 5%, preferably 1 to 2%, the blood collection status can be confirmed by visual inspection from the outside. Transparency can be ensured.

またプラスチック樹脂としてポリプロピレン樹脂を使用すると、毛細管吸引筒部1や全体を簡単に構成することができ、所定量のボロンを含有させても安価な採血具にすることができる。   When polypropylene resin is used as the plastic resin, the capillary suction tube portion 1 and the whole can be easily configured, and even if a predetermined amount of boron is contained, an inexpensive blood collecting tool can be obtained.

また毛細管吸引筒部1の吸い上げ側先端部を血液に接触すると、採血保持孔4による毛細管現象とボロン含有による親水性によって吸引採血保持孔4へと効果的に吸い上げることができる。その後、毛細管吸引筒部1の後方に形成した中間筒部2には、毛細管吸引筒部1の吸引採血保持孔4の内径に対して、その内径を急激に増大した中間室5を形成しているため、効果的に吸い上げられた血液で吸引採血保持孔4を満たすものの、中間筒部2側への毛細管現象による吸い上げは殆ど生じない。   Further, when the tip of the suction side of the capillary suction tube portion 1 comes into contact with blood, it can be effectively sucked into the suction blood collection holding hole 4 due to the capillary action by the blood collection holding hole 4 and the hydrophilicity due to the inclusion of boron. Thereafter, an intermediate chamber 5 is formed in the intermediate tube portion 2 formed at the rear of the capillary suction tube portion 1 so that the inner diameter is rapidly increased with respect to the inner diameter of the suction blood collection holding hole 4 of the capillary suction tube portion 1. Therefore, although the sucked blood collection holding hole 4 is filled with the blood sucked up effectively, the sucking up by the capillary phenomenon to the intermediate tube portion 2 side hardly occurs.

尚、採血具の具体的な構造は、上述したように図示の構造に限定するものではない。   In addition, the specific structure of the blood collection tool is not limited to the illustrated structure as described above.

以上説明したように本発明は、筒状本体の吸い上げ側先端部に透明または半透明のプラスチック樹脂製の毛細管吸引筒部1を形成し、前記毛細管吸引筒部1による毛細管現象を利用して血液を吸い上げる採血具において、前記毛細管吸引筒部1は、0.5〜5%のボロンを含有した前記プラスチック樹脂で形成したことを特徴とする。   As described above, the present invention forms a capillary suction tube portion 1 made of a transparent or translucent plastic resin at the suction side tip portion of the cylindrical main body, and uses the capillary phenomenon by the capillary suction tube portion 1 to blood. In the blood collecting device for sucking up blood, the capillary suction tube portion 1 is formed of the plastic resin containing 0.5 to 5% boron.

このような構成によれば、プラスチック樹脂に0.5〜5%のボロンを混合して製作しているため、少なくとも毛細管吸引筒部1を透明もしくは半透明としながら、ボロンを含有したことによる優れた親水性を生かして血液の吸い上げ効果を高めることができる。またボロンの含有量を制限することによって、透明性を保持することができるので、目視による採血状況などの確認も容易に行うことができる。   According to such a configuration, since the plastic resin is mixed with 0.5 to 5% boron, it is excellent because it contains boron while making at least the capillary suction tube portion 1 transparent or translucent. Taking advantage of the hydrophilicity, the blood sucking effect can be enhanced. In addition, since the transparency can be maintained by limiting the boron content, it is possible to easily check the blood collection status by visual observation.

また本発明は、上述の構成に加えて、ボロンの含有量を1〜2%としたことを特徴とする。   In addition to the above-described structure, the present invention is characterized in that the boron content is 1 to 2%.

このような構成によれば、ボロンの含有量をふさわしい範囲で、かつ少なく抑えることによって毛細管吸引筒部1の透明性を保持しつつ、優れた親水性を生かして血液の吸い上げ効果を高めることができる。   According to such a configuration, it is possible to enhance the blood sucking effect by making use of excellent hydrophilicity while maintaining the transparency of the capillary suction tube portion 1 by suppressing the boron content within a suitable range and by reducing it. it can.
