A handheld device for drawing fluid specimens, such as blood, comprising a structural body forming a manifold channel and a plurality of vial bodies integrated with the structural body, each of the vial bodies forming a port. A connection needle is seated within each of the ports. A valve element is slidably positionable with respect to the manifold channel, and slidably movable between a plurality of positions, each of the positions forming selective fluidic communication between the manifold channel and one port of the vial bodies, and preventing fluidic communication between the manifold channel and each of a plurality of remaining ports of the vial bodies. In one embodiment of this invention, the valve element is slidably movable with respect to the manifold channel to align one of a plurality of apertures formed in the valve element with respect to the manifold channel to form fluidic communication between the manifold channel and one of the ports of the vial bodies and preserve a vacuum formed in a vial connected at each of the remaining vial bodies. A needle is removably connectable to the structural body for drawing blood, for example, from a patient.
