Abstract

UNA JERINGUILLA PARA LA INYECCION DOSIFICADA DE UNA MEDICINA DESDE UN CARTUCHO RECAMBIABLE TIENE UN CUERPO QUE COMPRENDE UN SOPORTE DE CARTUCHO Y UN MECANISMO DOSIFICADOR POR EL QUE SE ESTABLECE UNA DOSIS QUE SE INYECTA POSTERIORMENTE HACIENDO AVANZAR SUCESIVAMENTE LA BARRA DEL PISTON PARA INTRODUCIR A PRESION EL PISTON EN EL CARTUCHO. EL MECANISMO DOSIFICADOR COMPRENDE UN HUSILLO ROSCADO Y UNA TUERCA QUE COOPERA CON EL HUSILLO. LA DOSIS SE ESTABLECE POR LA ROTACION RELATIVA DEL HUSILLO Y LA TUERCA, DONDE LA TUERCA SE MUEVE A LO LARGO DEL HUSILLO. LA POSICION DE LA TUERCA EN EL HUSILLO DEFINE CUANTO AVANZA LA BARRA DEL PISTON. EL HUSILLO Y LA TUERCA SE BLOQUEAN FRENTE A LA ROTACION RELATIVA CUANDO NO SE ACCIONA EL MECANISMO DOSIFICADOR PARA ESTABLECER UNA DOSIS. PARA ACCEDER AL SOPORTE DEL CARTUCHO SE ABRE UNA TAPA UNIDA AL CUERPO Y ACOPLADA AL MECANISMO DOSIFICADOR DE TAL MODO QUE SE DESBLOQUEA LA TUERCA EN SU POSICION EN EL HUSILLO CUANDO SE ABRE LA TAPA, Y EL MOVIMIENTO DE APERTURA DE LATAPA SE TRANSMITE A UN MECANISMO DE RETRACCION DE LA BARRA DEL PISTON.
