## Abstract

An intravenous therapy system, may include a processor; a data storage device; and a handheld ultrasound probe to detect structures within a patient's body, the handheld ultrasound probe including a video display device physically and operatively coupled to the handheld to display the structures within the patient's body and a magnetic field detector to detect the presence of a vascular access device (VAD) and provide closed-loop feedback to guide the VAD into a blood vessel within the patient's body detected by the ultrasound probe.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The intravenous therapy system of claim 1, wherein the video display device is configured to display a vein via a transverse planar image of the blood vessel within the patient's body.

### Claim 3 (depends on 1)

The intravenous therapy system of claim 1, further comprising a VAD recommendation module to provide feedback, via the video display device, a recommendation of which of a plurality of different VADs are to be used to access the blood vessel.

### Claim 4 (depends on 1)

The intravenous therapy system of claim 1, wherein the video display device provides a coronal planar view of the blood vessel within the patient's body depicting a projected path of the needle within the patient's body and a transverse planar view depicting the projected path of the needle within the patient's body.

### Claim 5 (depends on 1)

The intravenous therapy system of claim 1, wherein the processor is housed within the housing.

### Claim 6 (depends on 1)

The intravenous therapy system of claim 1, wherein the processor causes a projected path of the VAD to be overlaid onto ultrasonic images on the video display device during operation of the ultrasound probe.

### Claim 7 (depends on 1)

The intravenous therapy system of claim 1, wherein the housing comprises a button, wherein the button is configured to be actuated to automatically advance the needle along the trajectory via the linear motor in response to the trajectory of the needle being within the blood vessel detected by the ultrasound probe.

### Claim 8 (depends on 7)

The intravenous therapy system of claim 7, wherein actuation of the button is configured to be overridden in response to the trajectory not intersecting the blood vessel detected by the ultrasound probe.

### Claim 9 (depends on 8)

The intravenous therapy system of claim 8, further comprising an audio feedback device, a haptic feedback device, or a visual feedback device to indicate a projected path is not intersecting the blood vessel detected by the ultrasound probe.

### Claim 10 (depends on 1)

The intravenous therapy system of claim 1, wherein the trajectory indicator indicates a depth of the VAD, wherein the trajectory indicator is color coded to indicate whether the depth of the VAD is in line with the trajectory.

### Claim 11 (depends on 1)

The intravenous therapy system of claim 1, wherein the trajectory indicator indicates x- and y-coordinates of the VAD, wherein the trajectory indicator is color coded to indicate whether placement of the VAD is in line with the trajectory.
