The present invention relates to a percutaneous nephrostomy device, and more particularly to a percutaneous nephrostomy device suitable for protecting a catheter.

The manufacturing and excretion of urine in the human body is done by the kidney, the ureter, the bladder and the urethra. When this path is blocked, the kidneys continue to produce urine, which will cause the lumen of the upstream urinary tract to expand, which may lead to kidney dysfunction or uremia. When the cause of the obstruction cannot be removed by surgical methods or medication, it can only be treated by Percutaneous Nephrostomy (PCN), in detail, through the aid of a puncture needle and a metal wire. The drainage tube is placed in the urine collection system of the kidney via the skin, and the blocked urine is drained to the outside of the body, and the urine is collected through the catheter and the urine collection bag connected to the drainage tube.

Since the patient needs to drain the urine to the outside of the body by using the drainage tube for a long time, the drainage tube and the urinary catheter are designed as a hose for the patient to move. However, in actual operation, the soft drainage tube and the urinary catheter are easily broken and easily bent, which may cause abnormalities such as leakage of urine and unsmooth drainage of urine.

Accordingly, it is another object of the present invention to provide a percutaneous nephrostomy fixture that protects a tubing.
