Abstract: The embodiments herein provide an atraumatic urinary catheter. The atraumatic urinary catheter has a first tubule, a second tubule and a third tubule. The first tubule is provided with a first channel and a second channel. The first channel is wide and extended from a proximal end to a distal end of the first tubule and the first channel is open in both ends. The second tubule comprises a third channel, which is connected to a bladder cavity. The third tubule placed on the first tubule and the second tubule as a cover, to form a catheter's balloon. In order to avoid balloon explosion, the sterile water in the balloon is drained by the self-retaining mechanism of the catheter to prevent an irritation and tissue traumatization.
