Description

本発明は、指先穿刺の際に用いることができる指先駆血具に関する。   The present invention relates to a fingertip blood-driving device that can be used for fingertip puncture.

近年、POCT（ポイント・オブ・ケア・テスティング）と呼ばれる臨床現場で即時に臨床検査データを活用するための臨床検査が普及し、そのために用いられる機器が普及して利用されている。POCTは、臨床検査の現場での利用はもちろん、糖尿病に代表されるような慢性疾患に罹患した患者の自己の状態管理及び薬剤の投与管理にも利用され、また、ヘルスケアと言われる健康管理目的にも利用範囲は拡大している。さらに、最近では、薬局やコンビニエンスストア等の店舗で健康診断、セルフチェック健診を実施する利用の仕方も普及し始めている。そのような患者自身や健常人と言われるような人が自ら検査機器を使用して検査、測定を実施する場合には、静脈から血液を採取することはできず、指先等にランセットと呼ばれる穿刺血液採取冶具を使用して毛細管血液を採取することが一般的である。
指先穿刺血液の採取のしやすさには毛細血管の太さや血流量も然ることながら、穿刺器具の種類や穿刺方法等で個人間差、手技間差があり、また指先温度や環境温度にも依存する。しかし、個人間差、手技間差、環境に関係なく速やかに、測定に必要な十分量の血液採取を行う必要がある。なぜなら、速やかに採取することができなければ、浸出液(リンパ液)との混和や溶血が起こり得、また、皮膚表面の皮脂成分の混入や汗成分の混入が生じる可能性もあり、さらには、蒸発することもあるため臨床検査データにばらつきを生じる原因となるからである。
このような指先穿刺血液の採取は、従来は、患者の指先の毛細管血液を専用の穿刺針で刺し、自然に流れ出る血液を採取するか、又は指を絞って出血させて採取をしている。 In recent years, clinical tests called point-of-care testing (POCT) for immediately utilizing clinical test data have become widespread in clinical settings, and devices used for this purpose have been widely used. POCT is used not only in clinical laboratory settings but also in self-condition management and drug administration management for patients suffering from chronic diseases such as diabetes, and is also referred to as health care. The scope of use is also expanding for purposes. In addition, recently, the use of health checkups and self-checkups at stores such as pharmacies and convenience stores has begun to spread. When such a patient or a person who is said to be a healthy person conducts inspection and measurement using an inspection device himself, blood cannot be collected from the vein, and a puncture called a lancet is applied to the fingertip or the like. It is common to collect capillary blood using a blood collection jig.
The ease of collecting fingertip puncture blood varies depending on the type of puncture device and puncture method, and differences between individuals and procedures, as well as the thickness of blood capillaries and blood flow, and also depends on fingertip temperature and environmental temperature. To do. However, it is necessary to quickly collect a sufficient amount of blood necessary for measurement regardless of differences among individuals, differences between procedures, and the environment. This is because if it cannot be collected promptly, it may mix with the exudate (lymph) or hemolyze, and it may cause sebum components or sweat components on the skin surface. This may cause variation in clinical laboratory data.
Conventionally, such fingertip puncture blood is collected by piercing the capillary blood of the patient's fingertip with a dedicated puncture needle and collecting blood that flows out naturally or by squeezing the finger and bleeding it.

しかし、上記した従来の指先穿刺方法では、充分な採血量を得ることができない場合があり、検体量不足で再度穿刺しなければならない場合がある。このように複数回穿刺することは患者に対して心身共に負担をかけることになるので好ましくなく、また、臨床現場で即時に臨床検査データを必要としている場合には時間のロスが大きな問題となることがある。
さらに、最も重要な点は、不正確な測定データを出してしまう要因がある事であり、穿刺針で刺した後に自然に血液が流れ出ずに、指を絞って出血させる方法では、浸出液（リンパ液）との混和や溶血、皮膚表面の皮脂成分の混入、汗成分の混入、または蒸発により臨床検査データにばらつきを生じるという問題がある。
本発明は、上記した従来の問題点を解決して、必要量の血液を指先から採取し、正しい臨床検査データを出すことができる指先駆血具を提供することを目的としている。 However, with the above-described conventional fingertip puncture method, a sufficient blood collection amount may not be obtained, and puncture may have to be performed again due to insufficient sample volume. Puncturing multiple times in this way is not preferable because it puts a burden on the patient both physically and mentally, and time loss is a major problem when clinical laboratory data is needed immediately in the clinical setting. Sometimes.
Furthermore, the most important point is that there is a factor that results in inaccurate measurement data. In the method in which blood does not flow naturally after puncture with a puncture needle, ), Hemolysis, contamination of sebum components on the surface of the skin, contamination of sweat components, or evaporation, there is a problem of variation in clinical laboratory data.
An object of the present invention is to solve the above-mentioned conventional problems and to provide a fingertip blood-driving device capable of collecting a necessary amount of blood from a fingertip and outputting correct clinical test data.

以下、添付図面に示した実施例を参照しながら本発明に係る指先駆血具の実施の形態を説明していく。
図１は本発明に係る指先駆血具の概略側面図を示している。
図中、符号１は指先駆血具を示しており、この指先駆血具１は、基部２と、基部２に固定された支柱３とを有する。支柱３には、下向き円弧状の固定アーム４が固定されている。また、支柱３における前記固体アーム４の下方には上向き円弧状の加圧アーム５が、支柱３に沿って上下に摺動可能に設けられている。この加圧アーム５は、付勢手段を構成するバネ６によって固定アーム４側に向けて付勢されている。前記加圧アーム５には、指が係止可能な操作部７が設けられており、使用者が指で、バネ６の力に抗して操作部７を下方に押し下げることで加圧アーム５を下方に下げて固定アーム４と加圧アーム５との間の間隔を広げることができるように構成されている。
前記加圧アーム５の内側には、固定アーム４と加圧アーム５とで使用者の指を挟んだ時に指の中節骨のはら部分を押圧可能な押圧部８が形成されている。
この押圧部８は、図２に示すように、中節骨部分の両節に接触する支点部９，９と、前記支点部９，９より高い突起部１０とを有し、固定アーム４と加圧アーム５とで使用者の指を挟んだ時に、前記支点部９を支点として突起部１０で中節骨のはら部分を押圧するように構成されている。
駆血すべき位置ははらの部分、特に中央部付近が適切であることから、その部分を最も強く圧迫したい。その位置は指のふしとふしの間の中央部に位置することから、ふしの部分の押し当てに対して中央部にも突起部を設けるとともに、ふしの部分への押し当ての高さよりも中央部の教えての高さを高くしておくことが好ましい。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a fingertip blood-driving device according to the present invention will be described with reference to examples shown in the accompanying drawings.
FIG. 1 shows a schematic side view of a fingertip blood-driving device according to the present invention.
In the figure, reference numeral 1 denotes a fingertip blood-driving tool. The fingertip blood-driving tool 1 has a base 2 and a support 3 fixed to the base 2. A downward arc-shaped fixed arm 4 is fixed to the support column 3. Further, an upward arcuate pressure arm 5 is provided below the solid arm 4 in the column 3 so as to be slidable up and down along the column 3. The pressure arm 5 is urged toward the fixed arm 4 by a spring 6 that constitutes an urging means. The pressure arm 5 is provided with an operation portion 7 that can be locked by a finger, and the user presses the operation portion 7 downward against the force of the spring 6 with a finger by the user. It is comprised so that the space | interval between the fixed arm 4 and the pressurization arm 5 can be expanded by lowering.
Inside the pressure arm 5 is formed a pressing portion 8 capable of pressing the outer part of the middle phalanx of the finger when the user's finger is sandwiched between the fixed arm 4 and the pressure arm 5.
As shown in FIG. 2, the pressing portion 8 includes fulcrum portions 9 and 9 that come into contact with both nodes of the middle phalanx portion, and a protruding portion 10 that is higher than the fulcrum portions 9 and 9. When the user's finger is sandwiched between the pressurizing arm 5 and the fulcrum portion 9 as a fulcrum, the protruding portion 10 is used to press the elastic portion of the middle phalanx.
Since the position where the blood is to be pumped is appropriate, especially in the vicinity of the center, we would like to compress the part most strongly. Since the position is located at the center between the fingertips, a protrusion is also provided at the center for pressing against the upper part of the finger, and the center is higher than the height of the pressing on the upper part. It is preferable to keep the teaching height of the department high.

図２に示した実施例では、支点部９，９と突起部１０とは一体成型されているが、押圧部８の構造は本実施例に限定されることなく、図３に示すように、例えば、前記支点部９，９と前記突起部１０とは硬度が異なる可塑性材料で構成され得る。
指のはらの部分は平面ではなく凸形状しており、指のサイズはヒトそれぞればらばらであることは周知のとおりである。具体的には、突起部９の方が支点部８より硬度が低く、適正に圧迫、駆血するためには、柔軟性のある硬度が必要であり、好ましくは硬度40度以下である必要がある。このように構成することで駆血すべき部分を指の形、大きさに依存することなく駆血する効果を奏することができる。 In the embodiment shown in FIG. 2, the fulcrum portions 9 and 9 and the protrusion 10 are integrally molded, but the structure of the pressing portion 8 is not limited to this embodiment, as shown in FIG. For example, the fulcrum portions 9 and 9 and the protrusion 10 may be made of plastic materials having different hardnesses.
As is well known, the loose portions of the fingers are convex rather than flat, and the sizes of the fingers are different for each person. Specifically, the protrusion 9 has a lower hardness than the fulcrum part 8, and in order to properly press and drive blood, a flexible hardness is required, and preferably the hardness is 40 degrees or less. is there. By configuring in this way, it is possible to produce an effect of blood feeding without depending on the shape and size of the finger.

次に、図４及び図５を参照して、本発明に係る指先駆血具の第二の実施例について説明をしていく。

A pressing portion 23 is provided on the surface of the band 21. The pressing portion 23 includes a pair of fulcrum portions 24 projecting upward, and a protrusion 25 positioned between the pair of fulcrum portions 24 and higher than the fulcrum portion 24. The projecting portion 25 is configured separately from the fulcrum portion 24, and may preferably be formed of a material having a hardness lower than that of the fulcrum portion 24.
The fingertip blood-driving device 20 configured as described above is provided with one end of the band 21 at the other end in a state in which the protruding portion 25 of the pressing portion 23 is positioned so as to hit the outer portion of the middle phalanx portion. It is inserted into the ring 22 and pulled back, and the hooked portion 21a is pressed against the portion 21b raised in a loop shape and stopped.
As a result, the pair of fulcrum portions 24 come into contact with both nodes of the middle phalanx portion, and the protruding portion 25 can be effectively pressed with the fulcrum portion 24 as a fulcrum.

次に、図６及び図７を参照して本発明に係る指先駆血具の第三の実施例について説明をしていく。
