Abstract
An apparatus including a hollow body, an inlet fluidly coupled to the hollow body, a piston slidably engaged within the hollow body, and a filter module arranged within the hollow body between the inlet and piston. The piston and hollow body cooperatively generate a negative pressure, relative to ambient, within the hollow body during distal piston translation from a first position to a second position, thereby drawing a fluid, such as blood, through the filter module into the hollow body. The piston and hollow body cooperatively generate a positive pressure, relative to ambient, within the hollow body during piston translation from the second position to the first position to egress the filtered fluid from the hollow body. The filter module may include a filter housing, a filter medium disposed within the housing, and a body valve configured to seal an open distal face of the filter housing.
