Examples
Embodiment 1
[0025] Example 1: Single channel design.
[0026] Such as figure 1 , figure 2 As shown, a urinary catheter for preventing urinary catheter-associated infection includes a tube body 5, the front portion of the tube body 1 is provided with an end opening 6 or / and a side hole 3, and the cross section of the tube body 5 is triangular, triangular The vertices of are rounded. The cross section of the pipe body 5 is an equilateral triangle. The three sides of the triangle in the cross section of the pipe body 5 are bent to the inside of the triangle to form a parabola.
[0027] A detachable guide wire 2 is arranged inside the tube body 5 .
Embodiment 2
[0028] Example 2: Dual channel design.
[0029] Such as image 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 1 is: the tube body 5 is provided with an air bag 4 , and the tube body 5 is provided with an air bag duct 41 , and the air bag duct 41 communicates with the air bag 4 .
Embodiment 3
[0030] Example 3: Three-channel design.
[0031] Such as Figure 5 , Figure 6 As shown, the difference between the present embodiment and embodiment 2 is: the pipe body 5 is provided with an outflow passage 51 and an inflow passage 52, the opening 6 and the side hole 3 communicate with the outflow passage 51, and the front part 1 side of the pipe body is provided with The inflow hole 7 communicates with the inflow channel 52 . The cross-sectional area of the outflow channel 51 is larger than the cross-sectional area of the inflow channel 52 .
[0032] When the present invention is used, the tube body 5 is directly inserted into the urethra of a human body. For those who are difficult to insert, the tube body 5 can be inserted into the patient's body through the inherent guide wire 2, and the guide wire 2 is pulled out after adjusting the position properly. For the urinary catheter, inject physiological saline solution into the air bag 4, and properly fix the urinary ca...
