Abstract
Disclosed herein is a needle shield for an ultrasound probe. The needle shield fits closely with an ultrasound probe head, and any associated structures, and prevents accidental damage from needle punctures and the like. Further the needle shield includes a guide wedge that allows a user to stabilize the probe at an angle relative to the skin surface. This allows perpendicular needle access to the target vessel without the probe obstructing the needle. Further the needle shield includes an acoustic lens to modify the acoustic beam and compensate for the angle position of the probe head.
