The purpose of the present invention, which ties up to take, just bleeds liquid while can be easy to carry out taking for inspection blood, and the movement of blood caused by capillarity can be made to be easy, and can shorten blood sampling time. The present invention provides such blood sampling and just flows away except bag and blood sampling just flow away and remove group.The present invention provides a kind of blood sampling and just flows away except bag (B), it is by a plurality of 1st spacer portions (P1), bag ontology (21) inner area is divided into blood storage portion (S1) and air storage unit (S2) by the 2nd spacer portion (P2) and the 3rd spacer portion (P3), space (S) system formed between the 2nd spacer portion (P2) in what bag ontology (21) and the side wall surface (SD) of bag ontology (21) has the blood inflow path as the blood for being directed into blood storage portion (S1), and it is directed into the function of the exhaust flow path of the air of above-mentioned air storage unit (S2).本發明之目的係在採取初流血液之同時可容易地進行檢查用血液之採取，且可使毛細管現象所致之血液之移動容易，並可縮短採血時間。本發明提供此種採血初流去除袋及採血初流去除組。本發明提供一種採血初流去除袋(B)，其藉由複數個第1間隔部(P1)、第2間隔部(P2)及第3間隔部(P3)將袋本體(21)內部區劃成血液儲存部(S1)與空氣儲存部(S2)，形成於袋本體(21)內之第2間隔部(P2)與袋本體(21)之側部壁面(SD)之間之空間(S)係具有作為導入至血液儲存部(S1)之血液的血液流入路徑、及導入至上述空氣儲存部(S2)之空氣的排氣流路之功能。
