Protect peripheral nerve block patients from intraneural injection with the NerveGuard injection pressure limiter from Pajunk. Easily connecting between the syringe and injection tube, NerveGuard automatically closes its valve if pressure ever exceeds the safety threshold of 15 psi, stopping anesthetic administration. When the cannula is withdrawn and pressure drops, the valve reopens. This innovative design requires no additional visual contact; users only need to concentrate on the puncture and ultrasound device. Use it for single shots and continuous nerve blocks.
