12. A blood collecting apparatus according to claim 1, further comprising a reverse flow prevention means, provided on said second duct, for allowing a flow in a direction from said branch portion to said blood take-out port and for preventinga flow in a direction opposite to said direction from said branch portion to said blood take-out port.

13. A blood collecting apparatus according to claim 2, further comprising a reverse flow prevention means, provided on said second duct, for allowing a flow in a direction from said branch portion to said blood take-out port and for preventinga flow in a direction opposite to said direction from said branch portion to said blood take-out port.

14. A blood collecting apparatus according to claim 1, wherein an area of a cross-sectional surface of said second duct is set smaller than an area of a cross-sectional surface of said first duct.

15. A blood collecting apparatus according to claim 1, wherein at least one part of said second duct is constituted of a lumen of a tube; an inner diameter of said tube is set to the range of 0.5-2.0 mm; and an outer diameter of said tube isset to two-four times as large as said inner diameter thereof.

16. A blood collecting apparatus according to claim 1, wherein said blood take-out port is formed at an end of said second duct.
