<p>A catheter (1) made of an elastomeric silicone material and the like incorporates in its end sector operatively housed in the orifice (12) of the human organ (7), and in particular on its outer contact surface, a canalization (10) adapted to cause an additional flow of physiological liquid in general in course of expulsion, with guarantee of continuity even in case of a reduced delivery thereof, and, moreover, with a movement in a direction coaxial to the catheter (14a), and namely of its main inner drainage (14), in order to permit the axial escape of eventual bacterial colonies (6), as a consequence of said external movement of the liquid, which movement still results in being originated and ensured by the simple difference of the inner pressure in said orifice (13) relative to that of the surrounding outer ambient (14). </p> |
