Disposable replacement needle guides for the AccuSITE needle guidance system. The AccuSITE needle guide incorporates more user flexibility and advanced features to increase productivity during central line placement procedures. The new AccuSITE short-axis guide utilizes a two-part system consisting of a reusable bracket and sterile snap-on needle guide. The single-use guide offers an intuitive, easy-to-use design that is ready for use after just one click-no additional assembly is required. The guide features a large colored tab for simple quick-release function, allowing easy detachment of the needle from the transducer. Easy-to-read, color-coded gauge sizes and depths make it simple to identify the proper depth in a darkened room.

Each gauge size offers the most complete depths in the industry including: .5cm, 1cm, 1.5cm, 2cm, 2.5cm, 3cm and 3.5cm. For use with leading ultrasound manufacturers.
