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, comprising:

a catheter having a proximal end and a distal end, the catheter defining a lumen extending through the proximal end and the distal end, the catheter defining a plurality of openings adjacent the distal end;

an introducer having a proximal end portion and a distal end portion, the introducer defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer, the introducer configured to be transitioned between a first configuration, in which the catheter is in a first position, and a second configuration, in which the catheter is in a second position; and

an adapter configured to be coupled between the distal end portion of the introducer and a peripheral intravenous line, a portion of the catheter configured to move through a lumen defined by the adapter when the adapter is coupled to the introducer and the introducer is transitioned between the first configuration and the second configuration, the distal end of the catheter extending past an end of the peripheral intravenous line when the catheter is in the second position.

2. The apparatus of claim 1, wherein the lumen of the adapter is a first lumen defined by the adapter, the adapter defining a second lumen.

3. The apparatus of claim 1, wherein the lumen of the adapter is a first lumen, the adapter defining a second lumen, the first lumen having a first diameter and the second lumen having a second diameter, the first diameter being different from the second diameter.

4. The apparatus of claim 1, wherein the lumen of the adapter is a first lumen, the adapter defining a second lumen, the apparatus further comprising:

a backflow preventer coupled to the adapter adjacent the second lumen, the backflow preventer configured to selectively control a flow of fluid through the second lumen.

5. The apparatus of claim 1, wherein the plurality of openings adjacent the distal end of the catheter are disposed in a distal position relative to the peripheral intravenous line when the catheter is in the second position.

6. The apparatus of claim 1, further comprising:

a port coupled to the proximal end portion of the introducer, the port being in fluid communication with the catheter, the port configured to move bodily fluid to a volume outside the catheter when the catheter is in the second configuration.

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

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

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

10. The apparatus of claim 1, wherein the catheter is maintained entirely within the introducer when the introducer is in the first configuration.

11. The apparatus of claim 1, wherein the distal end portion of the introducer includes a locking mechanism, the locking mechanism configured to couple the introducer to the adapter.

12. An apparatus, comprising:

a catheter having a proximal end and a distal end, the catheter defining a lumen extending through the proximal end and the distal end, the catheter defining a plurality of openings along a circumference of the catheter adjacent the distal end;

an introducer having a proximal end portion and a distal end portion, the introducer defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer, the lumen of the introducer configured to receive the catheter therein, the catheter configured to move between a first configuration, in which the catheter is substantially disposed within the introducer, and a second configuration, in which at least a portion of the catheter is substantially outside of the introducer; and

an adapter coupled to the introducer, the adapter having a distal end configured to be coupled to a peripheral intravenous line, the adapter defining a first lumen and a second lumen, the first lumen having a first diameter and being configured to receive the catheter therethrough when the catheter is moved to the second configuration such that the distal end of the catheter extends past the distal end of the adapter, the distal end of the catheter extending through the peripheral intravenous line when the catheter is in the second configuration to place the plurality of openings in a distal position relative to the peripheral intravenous line.

13. The apparatus of claim 12, wherein the introducer is one of integrally coupled or removably coupled to the adapter.

14. The apparatus of claim 12, wherein the proximal end of the catheter is configured to be coupled to a fluid collection device.

15. The apparatus of claim 12, wherein the distal end portion of the introducer includes a locking mechanism configured to physically and fluidically couple the introducer to the adapter.

16. An apparatus, comprising:

a catheter having a proximal end and a distal end, the catheter defining a lumen extending through the proximal end and the distal end, the distal end of the catheter defining a plurality of openings;

an introducer having a proximal end portion and a distal end portion, the introducer defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer, the introducer configured to be transitioned between a first configuration, in which the catheter is in a first position, and a second configuration, in which the catheter is in a second position;

a locking mechanism coupled to the distal end portion of the introducer, the locking mechanism being disposed in a distal position relative to the plurality of openings defined by the distal end of the catheter when the introducer is in the first configuration; and

17. The apparatus of claim 16, wherein the proximal end portion of the adapter is transitioned from a first configuration, in which the proximal end portion of the adapter is substantially sealed, to a second configuration, in which the proximal end portion of the adapter is substantially open, when the proximal end portion of the adapter is coupled to the locking mechanism.

18. The apparatus of claim 16, wherein the adapter defines a first lumen and a second lumen, the first lumen configured to receive the catheter.

19. The apparatus of claim 16, wherein a distance between the proximal end portion of the introducer and the distal end portion of the introducer is a first distance when the introducer is in the first configuration, and a distance between the proximal end portion of the introducer and the distal end portion of the introducer is a second distance when the introducer is in the second configuration, the second distance being less than the first distance.
