Abstract

Un inyector a chorro que comprende un alojamiento para ser presurizado y teniendo una droga medica que se define por una pared que abarca la periferia y una pared inferior teniendo una superficie interna confrontando el interior del alojamiento y la superficie externa opuesta. La pared inferior tiene una abertura en forma de cono truncada de lado a lado extendiendose entre dichas superficies interna y externa y a traves de la cual dicha droga medica se expele desde el alojamiento y se transforma en un torrente de chorro delgado penetrando la piel de dicha persona a tratarse. Una insercion que tiene un cuerpo esencialmente en forma de cono se coloca para insertarse dentro de dicho alojamiento de manera que una porcion de dicho cuerpo en forma de cono, la pared de periferia la cual es esencialmente congruente a la pared de dicha abertura, se recibe en dicha abertura. Se establece al menos un pasaje entre dicha porcion de dicho cuerpo en forma de cono y la pared de apertura a traves de la cual la droga medica se expele desde el alojamiento. La droga entonces fluye a lo largo de dicho cuerpo en forma de cono para ser suministrada desde el punto del cuerpo en forma de cono como un torrente de chorro delgado coherente.
