In this embodiment, the driving circuit 36 controls the driving motor 37 to rotate, drives the shaft lever 38 to rotate and simultaneously drives the impeller 26 and the flow expander 30 to rotate, so as to drive urine to flow, force urine in the bladder to be pumped out and enter the urinary catheter 14 through the urine inlet 12, realize automatic urination, and can control the urination speed by controlling the rotation speed of the driving motor 37.

Specifically, a partition plate is provided in the lumen 11, and a drive circuit 36 and a drive motor 37 are provided on one side of the partition plate, and an impeller 26, a diffuser 30, and a urine stop valve 39 are provided on the other side of the partition plate. A plurality of urine inlets 12 are arranged on the wall of the tube cavity 11 at one side of the impeller 26 and close to the partition plate, and the urinary catheter channel 14 is formed between the partition plate and the urine stop valve 39. Since the urine inlet 12 is on the side of the lumen 11, the device of this embodiment is used with the lumen 11 implanted at the urethral opening and the urine inlet 12 in the bladder and the urine outlet 13 in the urethra.

As shown in fig. 15, the urine stop valve 39 comprises a valve cover 40, a valve rod 41, a valve body 42 and an elastic element 43, wherein the valve cover 40 is covered on the valve body 42, and the valve body 42 is fixedly connected with the lumen 11; the valve cover 40 is provided with a through hole communicated with the urine outlet 13, a flashboard 44 for closing or opening the through hole is arranged in the valve cover 40, the flashboard 44 is connected with the valve rod 41, and the valve rod 41 is arranged on the valve body 42; the elastic element 43 is sleeved on the valve rod 41, and two ends of the elastic element respectively lean against the flashboard 44 and the valve body 42. Under the action of the elastic element 43, the flashboard 44 is closely attached to the valve cover 40, the urine stop valve 39 is closed, and urine cannot flow to the urethra through the urine stop valve 39; when the impeller 26 and the diffuser 30 are rotated, the shutter 44 compresses the elastic member 43 by the urine hydraulic pressure, the urine stop valve 39 is opened, the through hole communicates the urine outlet 13 with the urine stop valve 39, and urine is discharged after passing through the urine stop valve 39.

Optimally, an annular sealing groove with an opening facing the valve cover 40 is arranged on the end face of the flashboard 44, a sealing ring 45 is arranged in the annular sealing groove, and the sealing ring 45 surrounds the through hole to prevent urine leakage when the urine stop valve 39 is closed.

Further, the valve body 42 is provided with a mounting hole through which the valve stem 41 passes, and the size of the hole is smaller than that of the valve cover 40. Further, an accommodation groove is provided on an end surface of the valve body 42 facing the valve cover 40, the accommodation groove communicates with the mounting hole, and the accommodation groove has a size larger than that of the mounting hole for accommodating the elastic member 43. The elastic member 43 may be a spring or the like.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
