Abstract
A device includes a pre-sample reservoir, an actuator mechanism, and a diverter. The pre-sample reservoir can be fluidically coupled to a delivery member to receive and isolate a predetermined volume of bodily-fluid withdrawn from a patient. The actuator mechanism is operably coupled to the pre-sample reservoir such that, when actuated, a negative pressure is formed in the pre-sample reservoir that urges the bodily-fluid to flow into the pre-sample reservoir. The diverter can selectively control fluid flow between the delivery member and the pre-sample reservoir. The diverter includes a flow control mechanism that defines a first fluid flow path and a second fluid flow path. The diverter is movable between a first configuration in which the bodily-fluid flows through the first fluid flow path to the pre-sample reservoir, and a second configuration in which the bodily-fluid flows through the second fluid flow path to a sample reservoir coupled to the diverter.
