Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Arrow direction in figure is flow direction of medium.
Specific embodiment
In order to deepen the understanding of the utility model, below we will the utility model is described in further detail in conjunction with attached drawing,
The embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
The embodiment for the catheter that the utility model one kind can pressurize as shown in figure 1, including urethral catheterization tube body 6, lead
Urinary catheter ontology 6 is equipped with sacculus 7, is equipped with inflated pipeline 8, inflated pipeline 8 and 7 gas of sacculus in urethral catheterization tube body 6
Connection；Drainage channel 10 is equipped in urethral catheterization tube body 6, drainage channel 10 includes mixing chamber 4 and diffusion room 5；Body fluid suction inlet 3
It is directly connected to mixing chamber 4 with the jet exit 2 of drainage channel 1, diffusion room 5 is connected to after mixing chamber 4；Diffusion room 5 is in canalis spinalis shape,
Vertebral canal expansion angle is 8-10 degree.6 front end of urethral catheterization tube body is equipped with body fluid suction inlet 3, and body fluid suction inlet 3 and drainage channel 10 connect
