Abstract: A blood draw device includes a catheter, an introducer having a proximal end portion and a distal end portion, an actuator movably coupled to the introducer, the actuator configured to move relative to the introducer to move the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which the distal end portion of the catheter is disposed beyond the distal end portion of the introducer such that at least a first portion of the catheter is disposed within the peripheral intravenous line when the introducer is coupled to the peripheral intravenous line, and a catheter support movably coupled to the introducer. The catheter support including a bracket portion and a hub portion including the passageway and extending from the bracket portion. The bracket portion of the catheter support is biased against a portion of the introducer.

Abstract: A fluid transfer device including a catheter, an introducer adapted to attach the device to a peripheral intravenous line (PIV), an actuator movably coupled to the introducer, and a catheter support movably coupled to the introducer. The catheter support is positioned between the actuator and the distal end of the introducer. The actuator moves the catheter between a first position disposed within the introducer and a second position where the end of the catheter extends beyond the end of the introducer and into the PIV. The catheter support defines a passageway. The catheter extends from the actuator through the passageway of the catheter support to the distal end of the introducer. As the actuator moves the catheter, the actuator contacts the catheter support and moves the catheter support with respect to the introducer. The device may also include a coupler for coupling the adapter to the catheter support.
