[0020] In one embodiment, such as Figure 2 As shown, the main body of the pipeline 1 is provided with an inflation pipe 31. The urinary catheter 21 and the flushing pipe 41 are respectively located on the left and right sides of the inflation pipe 31. One end of the inflation pipe 31 is connected to the airbag 5, and the other end of the inflation pipe 31 is connected to one end of the inflation branch pipe 3. One end of the urinary catheter 21 is connected to the urinary catheter port 13, and the other end of the urinary catheter 21 is connected to one end of the urinary catheter branch pipe 2. One end of the flushing pipe 41 is connected to the flushing port 12, and the other end of the flushing pipe 41 is connected to one end of the flushing branch pipe 4. The flushing pipe 41 and the inflation pipe 31 are independently provided inside the main body of the pipeline 1, and the flushing pipe 41 and the inflation pipe 31 are connected separately to the flushing port 12 and the airbag 5, which enhances the sealing and increases safety.

[0021] In one embodiment, such as Figure 1 As shown, the other end of the urinary catheter 2 is connected to the first drainage bag 8, which can record the patient's urine output. The other end of the inflatable catheter 3 is connected to the inflation device 51, and the other end of the flushing catheter 4 is connected to the shunt 6.

[0022] In one embodiment, such as Figure 2 and Figure 3As shown, the diverter 6 includes a main diverter 66, a first diverter branch pipe 61, a second diverter branch pipe 62, a baffle 63, a spiral spring 64, and a stop block 65. The flushing branch pipe 4 is inserted into the main diverter 66 and fixedly connected to it. A connecting pipe 91 is inserted into the first diverter branch pipe 61, and the connecting pipe 91 is connected to the second drainage bag 9, which can record the flushing volume. A water injection pipe 92 is inserted into the second diverter branch pipe 62.

[0023] In one embodiment, such as Figure 3 As shown, a baffle 63 is rotatably connected to the inner wall of the second diversion branch pipe 62, and a spiral spring 64 is sleeved on the rotating shaft of the baffle 63. The baffle 63 is located near the branch of the first diversion branch pipe 61 and the second diversion branch pipe 62. A stop block 65 is fixed to the inner wall of the first diversion branch pipe 61. The flushing fluid pressure directly pushes the baffle 63 open, and the baffle 63 is held in place by the stop block 65 to prevent the flushing fluid from flowing directly into the second drainage bag 9.

[0024] In one embodiment, such as Figure 4 As shown, the flow regulator 7 includes a regulator body 74, a pulley 71, a groove 72, and a roller 73. The bottom of the regulator body 74 is higher at the front and lower at the back. The left and right side walls of the regulator body 74 are provided with grooves 72. The roller 73 is fixed to the central axis of the pulley 71. The roller 73 is inserted into the grooves 72 on the left and right sides. It can control the opening and closing of the urinary catheter 2 and the flushing catheter 4, clamping only the urinary catheter 2 for flushing and drainage, or clamping only the flushing catheter 3 for urine drainage, or clamping both to train bladder function.

[0025] In one embodiment, such as Figure 2 As shown, the inner diameter of the connection of the main branch pipe 66 is equal to the outer diameter of the flushing branch pipe 4, the inner diameter of the connection of the first branch pipe 61 is equal to the outer diameter of the connecting pipe 91, and the inner diameter of the connection of the second branch pipe 62 is equal to the outer diameter of the water injection pipe 92.

[0026] Usage: Combine Figures 1-4 As shown, when the flushing branch tube 4 is clamped, the urine in the bladder is directly drained to the first drainage bag 8 through the urinary catheter branch tube 2. When flushing the bladder, the urinary catheter branch tube 2 is clamped, and the connecting tube 91 and the water injection tube 92 are inserted into the first shunt branch tube 61 and the second shunt branch tube 62, respectively. The flushing fluid in the water injection tube 92 enters the flushing pipe 41 through the flushing branch tube 4 and enters the bladder through the flushing port 12. The pressure of the flushing fluid directly pushes open the partition 63. The partition 63 is held in place by the stop block 65 to prevent the flushing fluid from flowing directly into the second drainage bag 9. After the flushing fluid is injected, the partition 63 is reset by the pulling force of the spiral spring 64. The flushing fluid enters the flushing pipe 41 through the flushing port 12 and is drained to the second drainage bag 9 through the flushing branch tube 4 and the connecting tube 91. When training bladder function, the urinary catheter branch tube 2 and the flushing branch tube 4 are both clamped.
