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...

Abstract

The invention discloses a urethral catheter capable of preventing related infection of the urethral catheter, belongs to the field of medical instruments, and solves the problem that the related infection of the urethral catheter is easily caused by the existing urethral catheter. The urethral catheter comprises a pipe body; the front portion of the pipe body is provided with an end opening or / and a side hole, the cross section of the pipe body is triangular, and the vertex of the triangle is a fillet. The pipe body is designed into the triangular pipe, and the three edges of the triangular pipe have an excellent supporting effect on urethra. Due to the design of the triangular pipe, related infection of the urethral catheter can be automatically prevented; on one hand, the contact area of urethral mucosa and the urethral catheter is minimized, the non-contact area is maximized, stimulation of the catheter to the urethral mucosa and adhesion and aggregation of bacteria on the surface of a carrier are reduced to the maximum extent, and formation of bacterial biofilms and urethral secretions is advantageously reduced; and on the other hand, a gap is formed between the urethra and the catheter body and serves as a drainage space, and the outer wall of the catheter body serves as a drainage track, so that local exudates and secretions can be discharged after the urethra operation.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a catheter for preventing urinary catheter-related infection. Background technique [0002] Indwelling urinary catheter is a basic technique commonly used in clinical diagnosis and treatment. It is widely used in urinary retention, dysuria, and drainage of urine after surgery. It is one of the commonly used clinical treatment and observation methods. Catheter-associated urinary tract infection is also the most common nosocomial infection. It has been reported abroad that about 35%-40% of hospital-acquired infections are urinary tract infections, and 90% of them are related to urinary catheters. There are also similar reports in China that the proportion of urinary tract infections caused by indwelling catheters in my country's nosocomial infections is 20.8%-31.7%, second only to respiratory tract infections. Catheter-associated urinary tract infection will not only inc...
