1. A probe delivery device, comprising:
a housing having a proximal end and a distal end, the distal end comprising a connector configured to couple the probe delivery device to an IV catheter device, the housing forming:
a compartment defined within the housing, at a location between the proximal end and the distal end; and
a fluid pathway separate from the compartment, the fluid pathway extending from another connector at the proximal end of the housing to the distal end of the housing to transfer a fluid through a length of the housing; and
a probe delivery mechanism housed in the compartment, the probe delivery mechanism including a probe that extends from the compartment and into the fluid pathway, the probe delivery mechanism being configured to advance the probe in a distal direction and through the distal end of the housing and to retract the probe in a proximal direction;
wherein the another connector at the proximal end of the housing comprises a vacuum tube receiver having a needle covered by a protective sheath, with the fluid pathway extending from the needle to the distal end of the housing,
wherein the probe delivery mechanism further comprises:
a spool around which the probe is wound,
a primary wheel that is positioned proximal to the spool, wherein the probe extends proximally from the spool, wraps around the primary wheel and then extends into the fluid pathway, and
one or more secondary wheels that are arranged arcuately around at least a portion of an exterior perimeter of the primary wheel, the probe passing between and contacting the primary wheel and the one or more secondary wheels, wherein the one or more secondary wheels are configured to hold the probe in contact with the primary wheel.
