Claim 18:
19. A fluid control device, the device comprising:
a housing having an inlet and an outlet, the housing at least partially defining each of a containment channel and a sampling channel between the inlet and the outlet;
a selectively permeable blood barrier, the blood barrier disposed at least partially in the housing between the containment channel and the outlet; and
a valve disposed at least partially in the housing between at least a portion of the sampling channel and the inlet,
the blood barrier configured to allow a gas to flow from the containment channel to the outlet in response to a first pressure differential between the inlet and the outlet such that a volume of blood flows into the containment channel,
the valve configured to transition from a first state to a second state in response to a second pressure differential greater than the first pressure differential between the valve and the outlet as a result of the volume of blood in the containment channel,
the valve in the first state configured to prevent the volume of blood from flowing from the inlet to the outlet via the sampling channel and the valve in the second state configured to allow a subsequent volume of blood to flow from the inlet through the sampling channel to the outlet.
