ABSTRACT:
A blood collector includes a cylindrical body having a closed end and an open end, and a hollow body is arranged coaxially at the closed end of the cylindrical body and has a hole communicating with the interior of the cylindrical body. A columnar body is arranged within the cylindrical body to be in tight contact with an inner wall thereof, with a distal end defining a blood collection space with the closed end of the cylindrical body. Further, the columnar body has a hole which allows the blood collection space to communicate with the outside. A freeze-dried blood anticoagulant mass is placed inside the blood collection space to cover an inner surface of the closed end of the cylindrical body and to block the hole of the hollow body. A filter is arranged across the hole of the columnar body. The filter is permeable to gases and impermeable to blood at least before being brought into contact with blood in the collection space.
