The device comprises a vacuum blood-drawing tube accommodating a blood-filtering unit, wherein the vacuum tube contains a space above the blood-filtering unit to preserve blood to be filtered and a partition wall under the blood-filtering unit to keep a backspace at reduced pressure, and the blood-filtering unit contains a communicating needle to break the partition wall at the bottom.
