Intravenous therapy system for blood vessel detection and vascular access device placement

An intravenous therapy system, comprising:

• a stand-alone device, comprising:
• a processor;
• a data storage device;
• and
• a housing comprising a distal end coupled to an ultrasound probe to detect a blood vessel within a patient's body;
• a video display device extending from the housing and operatively coupled to the ultrasound probe, wherein the video display device is configured to display the blood vessel detected by the ultrasound probe and a trajectory indicator;
• and
• a magnetic field detector configured to determine a position of a needle of a vascular access device (VAD) and provide data on a closed-loop feedback, wherein the processor is configured to calculate a trajectory of the VAD based on the data from the closed-loop feedback from the magnetic field detector, wherein the trajectory indicator indicates whether the VAD is in line with the trajectory as the VAD passes through the patient's body during operation of the ultrasound probe;
• a VAD chassis formed within a bottom of the housing and communicatively coupled to the processor, wherein the processor is configured to receive the data from the closed-loop feedback when the VAD is loaded within the VAD chassis;
• and
• a linear motor configured to automatically advance the VAD, when the VAD is loaded in the VAD chassis, into the patient's body along the trajectory, wherein the trajectory does not intersect with the ultrasound probe at the distal end of the housing.
