Abstract

1. Disposición de catéter 2.1 Una disposición de catéter de este tipo que comprende un catéter, que tiene un cuerpo de carcasa hueco, un elemento de tubo ajustado en un extremo distal del cuerpo de carcasa, un elemento de válvula que está dispuesto en el cuerpo de carcasa y está provisto de un paso de fluido, y un camino de conducción de fluidos que se extiende a través del cuerpo de la carcasa, el paso de fluidos y el elemento de tubo entre un lado de entrada proximal y un lado de salida distal, y que comprende una aguja hueca que, en un estado de disposición de la configuración del catéter, está hecha para extenderse longitudinalmente a través de la vía de conducción de fluidos y que, en un estado de uso de la disposición de catéter, se extrae de la vía de conducción de fluidos en la dirección proximal. 2.2 De acuerdo a la invención, el elemento de válvula tiene una porción de pared elástica a través de la cual se extiende el paso de fluido, donde la porción de pared es elásticamente deformable bajo la acción de una presión de fluido, en donde el paso de fluido en el estado de uso de la disposición de catéter, se puede cambiar por medio de una deformación elástica inducida por la presión del fluido de la porción de pared entre un estado abierto, en el que el paso de fluido está abierto, y un estado cerrado, en el que el paso de fluido está cerrado. 2.3 Uso en terapia de infusión.
