Claim 9:
10. 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 disposed at least partially in the housing in fluidic communication with the containment channel and the outlet, the blood barrier configured to allow a gas to flow from the containment channel to the outlet in response to a pressure differential between the inlet and the outlet such that a volume of blood flows from the inlet into the containment channel; and
a valve disposed at least partially in the housing between at least a portion of the sampling channel and the inlet, the valve in a first state configured to prevent the volume of blood from flowing from the inlet to the outlet, the valve configured to transition from the first state to a second state in response to an increase in a pressure differential between the valve and the outlet as a result of the volume of blood in the containment channel such that a subsequent volume of blood is drawn from the inlet through the sampling channel and to the outlet.
