Device (1) with mirror (1f) and coupling to bladder catheter (2c) to help carry out clean intermittent self-catheterization, which includes a support area (1c) in which, on its anterior face and essentially on its part A mirror (1f) of essentially circular shape is arranged at the top, and which is characterized in that in the lower part of the support area (1c) it has a grip area (1d) and in an essentially centered manner the coupling area (1e), to be attached to the bladder catheter (2c) at its proximal end essentially by a pressure mechanism and which makes it remain attached as if it were a single piece.
