[0039] Based on the first embodiment, specifically, Figure 1-4 As shown, a flushing hole is provided on the bottom surface of the water storage chamber 401, and a gasket 402 is provided in the flushing hole. There are four flushing holes formed in a circular array and equidistantly arranged on the bottom surface of the water storage chamber 401, so that under normal conditions, the gasket 402 can block the flushing hole, so that the saline injected into the water storage chamber 401 will not leak out, thereby allowing the polymer blocking membrane 4 to expand in volume and block the patient's urethra. When the saline is continuously injected, the gasket 402 can be flushed open due to the greater pressure in the water storage chamber 401, so that the saline is discharged from the flushing hole, thereby flushing the patient's urethra.
