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.

A method of using a fluid transfer device having an introducer, a lumen-defining device, and an actuator, the method comprising:
- coupling a distal end portion of the introducer to an indwelling peripheral intravenous line at least partially disposed in a vein of a patient;
- advancing the actuator relative to a portion of the introducer to move the lumen-defining device from a first position in which the lumen-defining device is proximal to the indwelling peripheral intravenous line to a second position in which a portion of the lumen-defining device extends through the indwelling peripheral intravenous line such that a distal end of the lumen-defining device is distal to a distal end of the indwelling peripheral intravenous line;
- establishing fluid communication between the lumen-defining device and a fluid reservoir;
- and
- transferring a volume of bodily fluid from the patient to the fluid reservoir via the lumen-defining device.
A method of using a fluid transfer device having an introducer, a lumen-defining device, and an actuator, the method comprising:
- coupling an adapter to an indwelling peripheral intravenous line at least partially disposed in a vein of a patient;
- coupling a distal end portion of the introducer to the adapter such that the adapter is disposed between the introducer and the indwelling peripheral intravenous line;
- advancing the actuator relative to the introducer to move the lumen-defining device from a first position in which the lumen-defining device is proximal to the adapter to a second position in which a portion of the lumen-defining device extends through the adapter and the indwelling peripheral intravenous line such that a distal end portion of the lumen-defining device extends beyond the indwelling peripheral intravenous line;
- establishing fluid communication between the lumen-defining device and a fluid reservoir;
- and
- transferring a volume of bodily fluid from the patient to the fluid reservoir via the lumen-defining device.
A method of using a fluid transfer device having an introducer, a lumen-defining device, and an actuator, the method comprising:
- inserting a peripheral intravenous line into a vein of a patient;
- after the peripheral intravenous line is inserted in the vein of the patient, coupling a distal end portion of the introducer to the indwelling peripheral intravenous line;
- advancing the actuator relative to the introducer to move the lumen-defining device from a first position in which the lumen-defining device is proximal to the indwelling peripheral intravenous line to a second position in which a portion of the lumen-defining device extends through the indwelling peripheral intravenous line such that a distal end portion of the lumen-defining device is disposed in the vein in a distal position relative to the indwelling peripheral intravenous line;
- establishing fluid communication between the lumen-defining device and a fluid reservoir;
- and
- transferring a volume of bodily fluid from the patient to the fluid reservoir via the lumen-defining device.
