The bladder ostomy tube 1 comprises an inner tube section 11 located inside the bladder and an outer tube section 12 located outside the body. The inner tube section 11 is provided with a first urine outlet 13 near the end and 4 circumferentially spaced apart bladders 14 near the bladder wall, with a second urine outlet 15 therebetween. Although the illustrated embodiment has 4 air bags 14, it should be understood that other numbers of air bags 14 may be provided as desired without departing from the scope of the present invention. The area of the second urination orifice 15 is small, and the level of the position where the second urination orifice is matched with the bladder fistulation tube 1 and enters the bladder is low, so that the normal urine suction by the first urination orifice 13 is not influenced. The second urination orifice 15 is protected by the air bags 14 on the two sides, even if the first urination orifice 13 is sucked by mistake, the bladder is changed into negative pressure, the bladder wall is collapsed, the gap between the two air bags is small, the bladder wall cannot block the second urination orifice 15, the air bags 14 on the two sides can effectively support the collapsed bladder wall, and a space is provided for urine suction.

With continued reference to figure 2, the bladder stoma tube 1 is a three-lumen structure comprising a balloon lumen 16, an irrigation lumen 17 and a urination lumen 18 therebetween. In the particular embodiment shown, the balloon lumen 16 and the flushing lumen are each disposed on an outer wall of the urination chamber 18. The balloon lumen 16 communicates at one end with the balloon 14 and at the other end has a non-return inflation port 161 located on the outer tube section 12. Injection of mannitol from the non-return inflation port 161 expands the balloon 14 to prevent the bladder stoma 1 from backing out. The non-return inflation port 161 prevents the outflow of mannitol injected into the balloon 14. The balloon 14 is inflated to expose the second urination port 15, and the design is to prevent the first urination port 13 from mistakenly sucking the bladder wall to cause urine retention when the urination pump works. The flush chamber 17 has a liquid inlet port 171 located on the inner tube segment 11 and a check flush port 172 located on the outer tube segment 12. Thus, irrigation can be given to the bladder by injecting irrigation fluid from the non-return irrigation port 172, and irrigation fluid is discharged from the first and second

urine discharge ports

13 and 15. If desired, certain medications may also be injected from the non-return flushing port 172 and into the bladder through the fluid inlet 171. The urination chamber 18 communicates with the first urination port 13, the second urination port 15, and the urination pump unit 4 (specifically, the first urination tube 44). That is, urine in the bladder enters the urination chamber 18 through the first urination port 13 and the second urination port 15 and is then discharged through the urination pump unit 4.

A pressure sensor 2 is arranged on the inner tube section 11 for detecting the pressure in the bladder. Preferably, the pressure sensor 2 is provided at the end of the inner tube section 11 to enable a more accurate measurement of the pressure within the bladder. The pressure sensor 2 may be a piezoresistive sensor or a piezoelectric sensor.
