Title
(EN) AN ELECTROTRANSPORT DELIVERY DEVICE WITH VOLTAGE BOOSTING CIRCUIT
(FR) DISPOSITIF D'ADMINISTRATION PAR ELECTRO-TRANSPORT AVEC CIRCUIT DE SURVOLTAGE
Abstract
(EN)
An electrotransport device (10) for delivering therapeutic agents includes an adjustable voltage boost multiple controller (100, 200) for boosting the voltage from a power source (102, 202) to a working voltage Vw having a value just sufficient to provide the desired therapeutic current level Il through the electrodes (108, 112), at least one of which contains the therapeutic agent to be delivered.
(FR)
Dispositif d'électro-transport (10) servant à l'administration d'agents thérapeutiques comprenant un contrôleur multiple de survolteur réglable (100, 200) pour porter la tension d'une alimentation électrique (102, 202) à une tension opérationnelle Vw, dont la valeur est juste suffisante pour qu'on obtienne l'intensité de courant thérapeutique voulue Il par les électrodes (108, 112), dont une au moins contient l'agent thérapeutique à administrer.
