ABSTRACT:
A blood container comprises a generally cylindrically shaped outer housing (11) having an upper portion, a lower portion and a bottom portion which declines downwardly to an outlet 3. A generally cylindrically shaped filter 2 is enclosed concentrically within the upper portion of outer housing for receiving blood at the top thereof and discharging filtered blood at the wall and base of the filter. A generally cylindrically shaped inner housing (4) extending from the base of the filter to the bottom portion of the outer housing. The container particularly includes means (5, 9, 9a, 9b, 11) for directing and restricting the flow of blood from the base of the filter for a gradual and smooth descent to the outlet which avoids the creation of bubbles and avoids any blood cell damage.
