Abstract

La presente invención se refiere a un dispositivo de surtido iontoforético de agente, eléctricamente impulsado, que incluye un ensamble de electrodo donador, un ensamble de contraelectrodo y una fuente de energía eléctrica adaptada para conectarse eléctricamente al ensamble de electrodo donador y al ensamble de contraelectrodo, el ensamble de electrodo donador comprendiendo un depósito de agente para contener un agente y adaptado para ser colocado en relación de transmisión de agente con una superficie del cuerpo; un electrodo donador adaptado para conectarse eléctricamente a la fuente de energía eléctrica; una membrana selectivamente permeable entre el electrodo y el depósito de agente, la membrana siendo permeable a especies de un peso molecular menor que un peso molecular predeterminado y substancialmente menos permeable a especies de un peso molecular mayor que el peso molecular predeterminado; en donde el agente es capaz de disociarse a iones de agente y contraiones de carga opuesta, los iones de agente teniendo un peso molecular mayor que el peso molecular predeterminado.The present invention relates to an electrically powered, iontophoretic agent dispensing device, including a donor electrode assembly, a counter electrode assembly, and an electrical power source adapted to electrically connect to the donor electrode assembly and counter electrode assembly, the donor electrode assembly comprising an agent reservoir for containing an agent and adapted to be placed in agent transmission relationship with a body surface; a donor electrode adapted to be electrically connected to the electrical power source; a selectively permeable membrane between the electrode and the agent reservoir, the membrane being permeable to species of a molecular weight less than a predetermined molecular weight and substantially less permeable to species of a molecular weight greater than the predetermined molecular weight; wherein the agent is capable of dissociating to agent ions and counter ions of opposite charge, the agent ions having a molecular weight greater than the predetermined molecular weight.
