Abstract
Disclosed herein is an ultrasound system for accessing a vasculature of a patient. The ultrasound system is configured to depict an enhanced ultrasound image of a subcutaneous portion of the patient including an icon surrounding a target vessel depicted on the display. The icon indicates to a clinician the target vessel is within range of a percentage vessel occupancy or vessel purchase length depending on a size of cannula or angle of insertion. The icon can also indicate blood flow strength, vessel type, or vessel deformation. The enhanced image can further include cannula trajectory guidelines and visual alerts for the clinician if the cannula tip can potentially backwall the vessel. Additional icons can indicate obstructions disposed on the cannula trajectory.
Claims32
An ultrasound system for accessing a vasculature of a patient, comprising:
- an ultrasound probe;
- a cannula;
- one or more processors;
- a display communicatively coupled to the one or more processors, the display for depicting an ultrasound image of a subcutaneous portion of the patient;
- and
- a non-transitory storage device communicatively coupled to the one or more processors, the non-transitory storage device having stored thereon logic, that when executed by the one or more processors, causes performance of operations including:
- depicting an enhanced image of the ultrasound image, including a first icon surrounding a target vessel;
- receiving updated information, including a dimension of the cannula, wherein the dimension of the cannula is derived by the ultrasound system;
- depicting the first icon in an updated state on the enhanced image according to the updated information;
- determining that a motion of the target vessel depicted in the ultrasound image, as caused solely by a positional instability of the ultrasound probe, exceeds a threshold equated to normal bodily motion;
- and
- providing a first alert advising a clinician to increase a positional stability of the ultrasound probe.
A method of accessing a blood vessel using ultrasonic imaging, comprising:
- providing an ultrasound system comprising:
- an ultrasound probe;
- a cannula;
- one or more processors;
- a display communicatively coupled to the one or more processors, and configured for depicting an ultrasound image of a subcutaneous portion of a patient;
- and
- a non-transitory storage device communicatively coupled to the one or more processors;
- depicting an enhanced image of the ultrasound image, including a first icon surrounding a target vessel;
- receiving updated information, including a dimension of the cannula, wherein the dimension of the cannula is derived by the ultrasound system;
- depicting the first icon in an updated state on the enhanced image according to the updated information;
- determining that a motion of the blood vessel depicted in the ultrasound image, as caused solely by a positional instability of the ultrasound probe, exceeds a threshold equated to normal bodily motion;
- and
- providing a first alert advising a clinician to increase a positional stability of the ultrasound probe.
