Claim 24:
25. A fluid control device, the device comprising:
a containment channel defined between an inlet and an outlet;
a sampling channel defined between the inlet and the outlet;
a selectively permeable blood barrier at a proximal end portion of the containment channel, 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 a blood source, through the inlet, and into the containment channel; and
an actuator between a portion of the containment channel and sampling channel, the actuator in a first state configured to prevent the blood from flowing from the inlet to the outlet via the sampling channel, the actuator configured to transition to a second state in response to a pressure differential in at least a portion of the sampling channel between the actuator and the outlet exceeding a threshold pressure as a result of the volume of blood in the containment channel, the actuator in the second state configured to allow blood to flow through the sampling channel to the outlet.
