A bodily-fluid transfer device includes a housing, a pre-sample reservoir, and an actuator. The housing defines an inner volume between a substantially open proximal end portion and a distal end portion that includes a port couplable to a lumen-defining device. The pre-sample reservoir is fluidically couplable to the port to receive a first volume of bodily fluid. The actuator is at least partially disposed in the inner volume and has a proximal end portion that includes an engagement portion and a distal end portion that includes a sealing member. The engagement portion is configured to allow a user to selectively move the actuator between a first configuration such that bodily fluid can flow from the port to the pre-sample reservoir, and a second configuration such that bodily fluid can flow from the port to a sample reservoir defined at least in part by the sealing member and the housing.

The present disclosure is a blood collection assembly that has a needle assembly fixedly coupled to a finger-activated actuator and tubing and the needle assembly has a needle. Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.
