Abstract

Adaptateur permettant de relier dynamiquement la sonde ou le moniteur d'un oxymètre à deux bornes à une sonde ou un moniteur à trois bornes. Cette opération s'effectue dynamiquement, les signaux d'attaque alternatifs émis par le moniteur de l'oxymètre fournissant un signal de commande de commutation des connexions de l'adaptateur. Les connexions de l'adaptateur sont constituées de préférence par des diodes, des transistors, ou tous autres dispositifs fonctionnels.
