Abstract

A relaxometric sensor for the detection of muscular contraction induced by electrical stimulation in the area of the hand using strain gauges as electrical transducers, is constructed in sandwich form from a resiliently deformable support element 1, a covering element 3 which is also resiliently deformable, and a resiliently deformable insert 2, positioned between the support element 1 and the covering element 3, which carries strain gauges 10, 11 on its upper and under sides, respectively. Depth of anaesthesia is measured by attaching the base 12 to the back of the hand and the tongue 13 to the thumb to detect the amount of thumb movement due to nerve stimulation. <IMAGE>
