Abstract

La présente invention porte sur un appareil de génération de signal de stimulation électrique basse fréquence pour lutter contre la nausée et les vomissements. En particulier, l'appareil comprend : un corps principal qui génère un signal de stimulation électrique basse fréquence ; une unité bande qui est portée sur le poignet d'un être humain, et comporte une paire d'électrodes correspondant au point de stimulation du poignet pour recevoir le signal de stimulation électrique basse fréquence provenant du corps principal et pour stimuler les points de stimulation ; et une unité de transfert qui transfère le signal de stimulation électrique basse fréquence généré par le corps principal à la paire d'électrodes. En conséquence, étant donné que le corps principal et l'unité bande sont séparés l'un de l'autre, le corps principal et l'unité bande peuvent être utilisés facilement et sans danger sans être mal utilisés ou utilisés de manière excessive. De plus, étant donné que toutes les fonctions nécessaires pour le fonctionnement du corps principal sont comprises, il n'y a pas besoin de disposer des pièces coûteuses et non nécessaires sur l'unité bande, réduisant ainsi les coûts de fabrication et empêchant le gaspillage de ressources.
