【発明の属する技術分野】本発明は穿刺針を備えた血液検査具に関し、より詳しくは、穿刺針によって刺通された皮膚から血液を採取し、これを直接検査薬に接触させて血液の検査をすることができる血液検査具に関する。 The present invention relates to relates to a blood test tool with a puncture needle, and more particularly, blood was collected from the skin was pierced by the puncture needle, which is brought into contact with the direct test agent test blood a blood test tool can be a to.

【0002】 [0002]

【従来の技術】血糖値の検査など血液検査のために微量の血液を採取する用具として、従来、ランセットが多用されている。 As tool for collecting traces of blood for testing, such as blood tests BACKGROUND ART blood glucose level, conventionally, the lancet is frequently used. このものは、先端に刃先を備えており、採血は、ランセットを指先等の皮膚に刺通して、その傷口から滲み出た微量の血液を採取することによって行われる。 This material has a cutting edge tip, blood collection, pierces the lancet into the skin, such as a fingertip, is performed by taking exuded traces of blood from the wound. ランセットは原則として毎採血毎に取り替えられ、 The lancet is replaced every every blood collection as a general rule,
使用済みのランセットは、通常、使用前に本体よりネジ切られ分離されていたキャップに刃先部分を突き刺して廃棄されている。 Used lancet is usually discarded pierce the blade portion to the cap which has been cut thread from the main body separated prior to use.

【0003】血液検査に際しては、従来のランセットを利用した採血方法では、一般に、傷口から滲み出た血液を専用の採血管を用いて採取し、この採取された血液を用いて血液検査を行う方法や、傷口に直接検査紙を押し当てて検査紙に血液を付着させて血液検査を行う方法が採用されている。 [0003] In blood test, the blood collection method using the conventional lancets, methods generally the exuded blood from the wound is collected using a special blood collection tube, performing blood tests using the collected blood and, how to adhere blood perform blood tests have been employed to test paper is pressed against the direct examination paper wound. しかしながら、上記のような方法は、 However, the method as described above,
血液採取と検査を別々に行うため、血液に接触する機会が多くなり、従って血液感染の機会が多くなるという欠点を有している。 To perform the inspection and blood sampling separately, the number of opportunities to contact with the blood, thus has the disadvantage that many opportunities for blood infection.

【0004】 [0004]

【発明が解決しようとする課題】本発明は上記の事情に鑑みてなされたもので、採血と血液検査を一回の操作で行うことのできる血液検査具を提供することを目的とする。 [0008] The present invention has been made in view of the above circumstances, and an object thereof is to provide a blood test device which can perform blood and blood test in a single operation.

【0005】 [0005]

【課題を解決するための手段】本発明者は、上記の課題を解決するために、検査薬と採血手段の一体化に付いて鋭意検討の結果、穿刺針の内腔に毛細管を挿着固定することにより、毛細管から採血された血液をその儘検査薬に接触させることができることに想到し、本発明に到達した。 The present inventors SUMMARY OF THE INVENTION To solve the above problems, a result of intensive studies with the integrated blood collection means and test agent, inserted secure the capillary in the inner cavity of the puncture needle by, conceive that can be brought into contact with collected blood from capillary without change test agent, thereby achieving the present invention. すなわち、本発明は、先端と基端を有する合成樹脂製管状部材と、該管状部材の内径と等しい外径を有しており該管状部材の内腔にその先端から刃先が所定長突出するように挿着固定された中空の穿刺針と、該穿刺針の内径と等しい外径を有しており該穿刺針の内腔にその刃先の位置まで挿着された毛細管、および該毛細管の基端に隣接して配設された検査薬を含んでなり、前記毛細管の基端が前記穿刺針の基端と同一または該穿刺針から突出した位置にあり、前記検査薬が外部から観察可能にされてなる、穿刺針を備えた血液検査具である。 That is, the present invention includes a synthetic resin tubular member having a distal end and a proximal end, so that the cutting edge by a predetermined length protrudes from the tip in the lumen of the tubular member has an outer diameter equal to the inner diameter of the tubular member a hollow puncture needle is inserted fixed to an inner diameter equal puncture has an outer diameter the puncturing needle lumen inserted by capillary to the position of the cutting edge, and the proximal end of the capillary of the puncture needle It comprises a test agent that is disposed adjacent to, in a position where the proximal end of said capillary tube protrudes from the proximal end and the same or puncture needle of the puncture needle, wherein the test agent is to be observed from the outside comprising Te, a blood test tool with a puncture needle. ここで、検査薬は濾紙に染み込まされたものや、脱脂綿に染み込まされたものが好ましく採用される。 Here, the test drugs and those impregnated on filter paper, those which are impregnated in cotton is preferably employed. また、毛細管の基端は管状部材の基端から所定長後退した位置にあっても、管状部材の基端と同じ位置にあってもよく、前者の場合、検査薬は管状部材の内腔に収容され、後者の場合、検査薬は例えば管状部材の基端を閉鎖する透明なキャップ部材の天面内壁に設けられる。 Also, the proximal end of the capillary tube is in a position which is a predetermined length backward from the base end of the tubular member may be in the same position as the base end of the tubular member, the former case, the lumen of the test agent tubular member housed, in the latter case, the test agent is provided on the top surface inner wall of the transparent cap member for closing the proximal end of the example the tubular member. 毛細管の基端が管状部材の基端から所定長後退した位置にある場合、管状部材の基端から毛細管の基端にかけての管状部材の内腔は拡径されていてもよい。 If the proximal end of the capillary tube is in a position a predetermined length backward from the base end of the tubular member, the lumen of the tubular member toward the proximal end of the capillary tube from the proximal end of the tubular member may be expanded.
