A membrane is disposed across the lumen, the membrane being hydrophobic and air permeable. A fluid chamber is formed within the lumen distal the membrane. A distal lumen opening being shaped and sized to retain blood within the lumen until the internal pressure of the lumen increases in response the a finger pressing against a proximal lumen opening.
