Claim 0:
1. A fluid control device, the device comprising:
a housing having an inlet fluidically coupleable to a blood source and an outlet fluidically coupleable to a fluid collection device, the housing defining at least a portion of each of a containment channel and a sampling channel between the inlet and the outlet;
a selectively permeable blood barrier, the blood barrier fluidically coupled to the containment channel and the outlet; and
an actuator disposed at least partially in the housing and configured to substantially obstruct a flow path between the inlet and the outlet when in a first state,
the blood barrier configured to allow a gas to flow through the blood barrier in response to a pressure differential between the inlet and the outlet, thereby allowing a volume of blood to flow into the containment channel,
in response to contact with at least a portion of the volume of the blood in the containment channel, the blood barrier configured to allow the pressure differential in at least a portion of the sampling channel between the actuator and the outlet to build to an extent sufficient to transition the actuator from the first state to a second state.
