Neurotips™ are sterile, single-use neurological examination pins, which eliminate the risk of cross-infection. They are semi-sharp, to reduce the risk of skin puncture particularly on fragile skin. Features and Benefits: Using a Neurotip in the Neuropen, a calibrated force of 40g may be safely exerted onto the skin, to identify patients with a decrease in sensation to sharpness/pain in small nerve fibers. Sterile semi-sharp examination pin. Sharpness testing tip. Removable cap.
