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.

An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

Various embodiments pertain to syringes having needles that automatically retract, and including syringe assemblies in which there is a means for damping any impact of the retracting needle, slowing the retracting needle, dissipating the kinetic energy of the needle, or the like, so as to lessen any jolt or disturbance experienced by the user.

A syringe apparatus (10) is provided which comprises a syringe portion having a syringe (12) or holder (24) adapted to receive a syringe (12) therein, the syringe portion having a rear grip (38) for seating in or against a user's hand and a front grip (40) formed at or adjacent to a tip end (22) of the syringe portion; and a movable member (30) engagable with a plunger (16) of the said syringe (12), the movable member (30) having a finger grip (32) at or adjacent to a tip end (22) thereof, the movable member (30) being engaged with the syringe portion and configured to move relative to the rear grip when a user applies a force at the finger grip (32); wherein the front and rear grips (40, 38) are formed as lateral projections (40a, 40b; 38a, 38b) with respect to the movable member (30).

A bodily fluid collection system for collecting a bodily fluid from a patient, and a bodily fluid transfer system for transferring collected bodily fluid to a second collection device. A collection adapter has a connection port configured to securely connect with a hub of a syringe, and a collection interface opposite the connection port creates a fluid conduit to the barrel via the connection port and an inlet of the hub. A proximal adapter is connected to a proximal end of the fluid channel from the patient, and configured to removably interact with the collection interface of the collection adapter to connect the proximal end of the fluid channel to the barrel via the fluid conduit and inlet to the barrel to allow conveyance into the barrel of the at least some of the sampling portion of the sample of bodily fluid. The proximal adapter can be removed to allow access to any bodily fluid collected by the syringe.
