Abstract

An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

Claims

1. An apparatus for phlebotomy through an indwelling intravenous line having a proximal end and a distal end, comprising:

a catheter having a proximal end and a distal end and defining a lumen therethrough;

an introducer having a proximal end and a distal end and defining a lumen therethrough, the introducer configured to receive the catheter therein, the distal end of the introducer configured to be coupled to the proximal end of the indwelling intravenous line; and

an actuator having a portion maintained within the introducer and coupled to and in contact with the catheter, the actuator configured to move relative to the introducer such that the portion of the actuator moves within the introducer to move the catheter between a proximal position in which the catheter is disposed within the introducer and a distal position in which the catheter is distal to and at least partially outside the introducer;

the catheter being disposed within, and extending past the distal end of the indwelling intravenous line when in the distal position.

2. The apparatus of claim 1, further comprising:

an adapter coupled between the distal end of the introducer and the proximal end of the indwelling intravenous line.

3. The apparatus of claim 1, further comprising:

an adapter coupled between the distal end of the introducer and the proximal end of the indwelling intravenous line, the adapter including a first lumen and a second lumen, the first lumen having a diameter.

4. The apparatus of claim 3, wherein the first lumen has a first diameter and the second lumen has a second diameter, the first diameter being different from the second diameter.

5. The apparatus of claim 3, further comprising a backflow preventer coupled to the adapter adjacent the second lumen.

6. The apparatus of claim 1, wherein the catheter defines a plurality of openings adjacent the distal end of the catheter.

7. The apparatus of claim 1, further comprising a port coupled to the proximal end of the introducer, the port being in fluid communication with the catheter, the port further configured to move bodily fluid to a volume outside the catheter when the catheter is in the second position.

8. The apparatus of claim 1, further comprising one of a sheathed needle, a syringe, a locking mechanism, or an access port fluidically coupled to the catheter.

9. The apparatus of claim 1, wherein the actuator is movably coupled to the introducer and is fixedly coupled to the catheter.

10. The apparatus of claim 1, wherein the catheter is between 18 gauge and 26 gauge.

11. The apparatus of claim 1, wherein the catheter has a Shore durometer of approximately 20 Shore A to 50 Shore D.

12. The apparatus of claim 1, wherein the entirety of the catheter is maintained within the introducer when in the first position.

13. The apparatus of claim 1, wherein a portion of the catheter extends past the proximal end of the introducer when in the first position.

14. An apparatus for phlebotomy through an indwelling intravenous line having a proximal end and a distal end, comprising:

a catheter having a proximal end and a distal end and defining a lumen therethrough;

an introducer having a proximal end and a distal end and defining a lumen therethrough, the introducer configured to receive at least a portion of the catheter therein, the distal end of the introducer configured to be coupled to the proximal end of the indwelling intravenous line; and

an actuator coupled to and in contact with at least the portion of the catheter within the introducer, the actuator configured to move relative to the introducer such that a portion of the actuator moves within the introducer to move the catheter between a proximal position in which the catheter is disposed within the introducer and a distal position in which the catheter is distal to and at least partially outside the introducer;

the catheter being disposed within, and extending past the distal end of the indwelling intravenous line when in the distal position.

15. The apparatus of claim 14, further comprising:

an adapter coupled between the distal end of the introducer and the proximal end of the indwelling intravenous line.

16. The apparatus of claim 14, further comprising:

an adapter coupled between the distal end of the introducer and the proximal end of the indwelling intravenous line, the adapter including a first lumen and a second lumen, the first lumen having a diameter.

17. The apparatus of claim 16, wherein the first lumen has a first diameter and the second lumen has a second diameter, the first diameter being different from the second diameter.

18. The apparatus of claim 16, further comprising a backflow preventer coupled to the adapter adjacent the second lumen.

19. The apparatus of claim 14, wherein the catheter defines a plurality of openings adjacent the distal end of the catheter.

20. The apparatus of claim 14, further comprising a port coupled to the proximal end of the introducer, the port being in fluid communication with the catheter, the port further configured to move bodily fluid to a volume outside the catheter when the catheter is in the second position.

21. The apparatus of claim 14, further comprising one of a sheathed needle, a syringe, a locking mechanism, or an access port fluidically coupled to the catheter.

22. The apparatus of claim 14, wherein the actuator is movably coupled to the introducer and is fixedly coupled to the catheter.

23. The apparatus of claim 14, wherein the catheter is between 18 gauge and 26 gauge.

24. The apparatus of claim 14, wherein the catheter has a Shore durometer of approximately 20 Shore A to 50 Shore D.

25. The apparatus of claim 14, wherein the entirety of the catheter is maintained within the introducer when in the first position and the actuator is coupled to a portion of the catheter.

26. The apparatus of claim 14, wherein a portion of the catheter extends past the proximal end of the introducer when in the first position, the portion of the catheter that extends past the proximal end of the introducer is different from the portion of the catheter coupled to the actuator.
