TuohySono's tip is highly visibility under ultrasound. Moreover, incorporated along the distal 20mm of the cannula “Cornerstone” reflectors ensure ultrasound reflection at steep and shallow angles alike. Cornerstone reflectors are arranged 360° about the cannula ensuring definite and clear identification in any rotation of the cannula.

The embossed structures in the Cornerstone Reflectors form three surfaces which meet each other at a 90° angle guaranteeing direct or indirect reflection of the ultrasound waves - even at very steep insertion angles. Cornerstone Reflectors are arrayed along a length of 20 mm from the tip of the needle and moreover are arranged 360 degrees about the needle thus ensuring clear identification of the needle in any orientation or angle.


For the prevention of connection and injection errors. 
NRFit-Tuohy® is now available. Contact us for further information.

The Tuohy epidural needle is available with or without Cornerstone Reflectors (TuohySono) for Ultrasound application and optionally "with stainless steel or plastic stylet".
