Abstract
A blood filter device comprising: a housing comprising an outer wall and a first inlet, a first outlet and a second outlet; a membrane which is capable of separating plasma from the blood, wherein the membrane forms an inner chamber; a leukocyte and oxygen and/or carbon dioxide depletion media disposed wherein the inner chamber, the leukocyte and oxygen and/or carbon dioxide depletion media is capable of depleting leukocytes and oxygen and/or carbon dioxide from the blood; an outer chamber disposed between the outer wall and the membrane, wherein the plasma which permeates through the membrane enters the outer chamber and exits the filter device via the first outlet; whereby the blood which has been depleted of oxygen and/or carbon dioxide, leukocytes and plasma exists and filter device via the second outlet.
