Compared with the prior art, the utility model the advantage lie in: the outer walls of the starting section and the middle section of the far end of the water bag of the catheter are provided with the medicine bag, the periphery of the wall of the medicine bag is provided with a plurality of rows of micropores, and after administration, local anesthetic is fully distributed at the contact part of the catheter and the inner wall of the urethra through the micropores, so that the problem that a patient suffers from urinary tract pain and cannot tolerate after catheterization is solved, a series of complications caused by severe circulation fluctuation due to serious discomfort of the catheter are effectively prevented, the medicine bag is particularly suitable for patients needing long-term catheterization, and antibiotics can be prevented from being infected and the like through the medicine bag.

As an improvement, the diameter of the medicine outlet hole is 0.1mm-0.12mm, the problem that the dosage of anesthesia cannot be mastered due to the overlarge diameter of the medicine outlet hole is solved, and the small-diameter medicine outlet hole can ensure that the dosage of anesthesia cannot be harmful to the health.

As an improvement, the catheter and the medicine bag are made of medical silica gel materials, the flushing pipe is made of corrosion-resistant medical silica gel materials, and the flushing pipe is arranged inside the catheter and needs to resist the two-way corrosion of urine and flushing agents.

As an improvement, the number of the medicine outlet holes is 30-50, and the medicine outlet holes are uniformly distributed on the whole medicine bag, so that the medicine can be uniformly administered, and the discomfort caused by the ureter can be relieved.

As an improvement, the diameter of the catheter close to the urine outlet is larger than that of the catheter close to the urine inlet, so that the urine outlet is not blocked and the catheter can be used for a long time.
