The application provides a catheterization device for irrigation administration, and relates to the field of medical devices, comprising a catheter and a liquid storage bag, the liquid storage bag is sleeved outside the catheter and is attached to the side wall of the catheter, a through hole connected to the inner cavity of the liquid storage bag is arranged on the side wall of the catheter, a blocking diaphragm capable of being broken under the action of a set pressure is arranged in the through hole, and a blocking piece is arranged in the inside of the catheter in the covering area of the liquid storage bag to block the catheter under the action of the pressure of the side wall of the catheter. In view of the problem that pollution is easily caused during the current bladder irrigation, the flushing liquid is pre-stored in the liquid storage bag, so that the liquid storage bag becomes a convenient flushing device. The flushing liquid is isolated from the outside world before flushing, so that pollution is avoided. When in use, the liquid storage bag is squeezed to make the flushing liquid pass through the through hole and be input along the catheter, so that the operation is convenient and secondary infection is avoided.
