Abstract

Dispositif de protection contre les brûlures accidentelles. Ce dispositif est caractérisé par l'utilisation de l'épiderme du patient pour relier entre elles électriquement deux parties métalliques d'une plaque indifférente double, reliées respectivement à deux conducteurs distincts de retour du courant haute fréquence engendré par un générateur de bistouri électrique, de façon à assurer la continuité d'un circuit électrique d'alimentation en courant continu basse tension d'un dispositif de commande d'alarme. Application en particulier pour équipements de bistouris électriques de salles d'opérations chirurgicales.
