Description

本発明は採血用注射器に用いる採血針に関するものである。   The present invention relates to a blood collection needle used for a blood collection syringe.

血管が極めて細い患者や乳幼児又は静脈圧が低い場合或は血液量が少ない場合で真空管採血が困難な場合がある（例えば特許文献１、２）。   In some cases, patients with very thin blood vessels, infants, or when the venous pressure is low or the blood volume is low, it is difficult to collect the vacuum tube (for example, Patent Documents 1 and 2).

しかし真空管採血による合併症のリスクが大きい場合には注射器と従来の注射針を用いた採血が行われる（例えば非特許文献１）。   However, when the risk of complications due to vacuum tube blood collection is high, blood collection using a syringe and a conventional injection needle is performed (for example, Non-Patent Document 1).

注射器と従来の注射針を用いた採血では注射針を減圧採血管又は陰圧試験管（スピイツ）内にゴム栓から刺入し、注射器内の採血（検体）をスピイツ内に直接減圧により採血した。   In blood collection using a syringe and a conventional syringe needle, the syringe needle was inserted into a vacuum blood collection tube or a negative pressure test tube (speech) from a rubber stopper, and blood collection (specimen) in the syringe was collected directly into the spine by decompression. .

このような採血手順では右手に持った注射器の注射針を一旦体外に露出し、この注射針をスピイツ内に刺入する手順又は動作が行われ、針刺し事故を起こしやすいという危険性があり、かつ時間を要し、陰圧（負圧）及び針の内径（２２ゲージ以下）によっては血液中の赤血球が壊れ溶血して検体（検査用の血液）に用い難いという問題があった。   In such a blood collection procedure, there is a risk that the injection needle of the syringe held in the right hand is once exposed outside the body, and the procedure or operation for inserting the injection needle into the spine is performed, and there is a risk that a needle stick accident is likely to occur, and Depending on the negative pressure (negative pressure) and the inner diameter of the needle (22 gauge or less), there was a problem that red blood cells in blood were broken and hemolyzed, making it difficult to use for specimens (test blood).
