Blood draw device

A blood draw device comprising:

• a catheter having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion and the distal end portion;
• an introducer having a proximal end portion and a distal end portion, the introducer defining an inner volume configured to movably receive the catheter, the distal end portion of the introducer having a lock configured to couple the introducer to an indwelling peripheral intravenous line;
• an actuator movably coupled to the introducer, the actuator having a first portion disposed outside of the introducer and a second portion disposed in the inner volume of the introducer and coupled to the proximal end portion of the catheter, 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 indwelling peripheral intravenous line when the introducer is coupled to the indwelling peripheral intravenous line;
• and
• a catheter support defining a passageway, movably coupled to the introducer, and positioned between the actuator and the distal end portion of the introducer, the catheter support having a first end and a second end positioned opposite the first end,
• wherein the catheter extends from the second portion of the actuator through the passageway of the catheter support to the distal end portion of the introducer, and during movement of the actuator to move the catheter from the first position to the second position, the actuator contacts the catheter support and moves the catheter support with respect to the introducer, and
• wherein the second end of the catheter support comprises a nose cone configured to engage a lead-in surface of the introducer.

• a catheter support defining a passageway, movably coupled to the introducer, and positioned between the actuator and the distal end portion of the introducer,
• wherein the catheter extends from the second portion of the actuator through the passageway of the catheter support to the distal end portion of the introducer, and during movement of the actuator to move the catheter from the first position to the second position, the actuator contacts the catheter support and moves the catheter support with respect to the introducer, and
• wherein the introducer comprises a detent and a plurality of ribs and the distal end of the actuator comprises a tab configured to engage the detent and the plurality of ribs as the actuator is moved relative to the introducer.

A blood draw device comprising:

• a catheter having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion and the distal end portion;
• an introducer having a proximal end portion and a distal end portion, the introducer comprises a first member attached to a second member, the introducer defining an inner volume configured to movably receive the catheter, the distal end portion of the introducer having a lock configured to couple the introducer to an indwelling peripheral intravenous line;
• an actuator movably coupled to the introducer, the actuator having a first portion disposed outside of the introducer and a second portion disposed in the inner volume of the introducer and coupled to the proximal end portion of the catheter, 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 indwelling peripheral intravenous line when the introducer is coupled to the indwelling peripheral intravenous line;
• and
• a catheter support defining a passageway, movably coupled to the introducer, and positioned between the actuator and the distal end portion of the introducer,
• wherein the catheter extends from the second portion of the actuator through the passageway of the catheter support to the distal end portion of the introducer, and during movement of the actuator to move the catheter from the first position to the second position, the actuator contacts the catheter support and moves the catheter support with respect to the introducer, and
• wherein the first member of the introducer comprises one of a peg and an opening and the second member of the introducer comprises the other of the peg and the opening, the peg secured within the opening via an ultrasonic weld to secure the first member of the introducer to the second member of the introducer.
