PROBLEM TO BE SOLVED: To provide a vascular access device for reducing the risk of developing cardiovascular diseases compared to conventional devices.SOLUTION: The vascular access device 1 comprises a first tubular connecting member 10 that is configured to be connected to a vein, a second tubular connecting member 20 that is configured to be connected to a vein at a position downstream of the position of the vein where the first connecting member 10 is connected, and a body 30 including puncture members 32 and 34. An inner flow passage 40 is formed inside the first connecting member 10, the second connecting member 20, and the body 30, linking the end of the first connecting member 10 to the end of the second connecting member 20. In the flow interval from an upstream connection hole 12 to a first downstream connection hole 22 or to a second downstream connection hole 24, the inner flow passage 40 is divided into a first passage flow 42 linking the upstream connection hole 12 to the first downstream connection hole 22 and a second passage flow 44 linking the upstream connection hole 12 to the second downstream connection hole 24.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来よりも心血管疾患の発生リスクを低減することが可能な血管アクセスデバイスを提供する。【解決手段】静脈と接続可能に構成された、管状の第1接続部10と、第1接続部10が接続される静脈の位置よりも下流側の位置の静脈と接続可能に構成された、管状の第2接続部20と、穿刺部32,34を有する本体部30とを備える血管アクセスデバイス1。第1接続部10、第2接続部20及び本体部30の内部には、第1接続部10の端部から第2接続部20の端部まで連通する内部流路40が設けられている。内部流路40は、上流側連通孔12から下流側第1連通孔22及び下流側第2連通孔24までの区間において、上流側連通孔12から下流側第1連通孔22に至る第1流路42と、上流側連通孔12から下流側第2連通孔24に至る第2流路44とに分岐している。【選択図】図3
