In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, 2 and 3, the present utility model discloses a urinary catheterization apparatus 100, which includes a guiding assembly 10, an indwelling assembly 20 mounted on the guiding assembly 10, and a guiding assembly 30 cooperating with the guiding assembly 10.

Referring to fig. 2, 3 and 4, the diversion assembly 10 includes a drainage tube 11, a drainage cap 12 mounted at one end of the drainage tube 11, a first sealing member 13 mounted at the other end of the drainage tube 11, a catheter 14 inserted into the first sealing member 13 and communicating with the drainage tube 11, and a second sealing member 15 mounted at one end of the catheter 14 remote from the drainage tube 11. The drain tube 11 includes a side wall 111 and a drain lumen 112. The side wall 111 encloses the drainage cavity 112. The drainage cap 12 is provided with a drainage hole 121 and a fixing groove 122. The drainage hole 121 communicates with the drainage cavity 112. The first sealing member 13 is matched with the drainage tube 11 and the catheter 14 so that the drainage tube and the catheter are in sealing connection. The urinary catheter 14 includes a tube wall 141 and a urinary lumen 142. The catheter wall 141 encloses the urinary catheterization cavity 142. The second seal 15 cooperates with the urinary catheter 14, the guide assembly 30 to sealingly connect the two.

Referring to fig. 2, 3 and 4, the indwelling assembly 20 includes an indwelling balloon 21 mounted on the drainage tube 11 and an inflation tube 22 for inflating the indwelling balloon 21. When inflated through the inflation tube 22, the indwelling balloon 21 is inflated; when the inflation tube 22 is opened, the indwelling balloon 21 can be deflated by the inflation tube 22, thereby reducing the volume of the indwelling balloon 21.

Referring to fig. 2, 3 and 5, the guide assembly 30 includes a guide tube 31, a guide wire 32 disposed in the guide tube 31, and a balloon 33. The guide tube 31 includes a fixed balloon 311 disposed at one end of the guide tube 31 and a guide lumen 312. The guide chamber 312 communicates with the fixed balloon 311. The guidewire 32 is disposed within the guide lumen 312. The balloon 33 is mounted at the end of the guide tube 31 facing away from the fixed balloon 311. When the balloon 33 is pressed, the balloon 33 may inflate the guide tube 31.

In use, the guide assembly 30 is first inserted into the second seal 15 and extended into the drain tube 11 such that the fixing balloon 311 is opposite the fixing groove 122. Then, the balloon 33 is pressed, and at this time, the balloon 33 inflates the guide tube 31, so that the fixing balloon 33 is inflated and enters the fixing groove 122, thereby fixing the guide assembly 30 with the drainage cap 12. Since the guide assembly 30 is fixed with the drainage cap 12 by the fixing balloon 311, the guide assembly 30 does not slide out of the drainage lumen 12. Next, the urinary catheterization assembly 10 is inserted into the bladder through the urethra and the indwelling balloon 21 is inflated through the inflation tube 22, so that the indwelling balloon 21 is inflated, thereby securing and indwelling the urinary catheterization assembly 10 in the bladder by the inflated indwelling balloon 21. Then, the balloon 33 is released so that the fixing balloon 311 can be exhausted outward, thereby reducing the volume. When the air is exhausted from the fixing air bag 311, the volume of the fixing air bag 311 is reduced, and the fixing air bag 311 slides out of the fixing groove 122, so that the guide assembly 30 can be pulled out of the guide assembly 10. At this point, urine will enter the drainage lumen 112 through the drainage aperture 121 and be directed out through the urinary lumen 142.

Compared with the prior art, the catheterization device 100 of the present utility model has the advantages that the fixing air bag 311 is arranged on the guiding component 30, and the fixing groove 122 matched with the fixing air bag 311 is arranged on the guiding component 10, so that the guiding component 30 and the guiding component 10 are fixed together, the guiding component 30 can better support the guiding component 10, the defect that the guiding wire easily slides out of the catheter in the prior art is avoided, and the success rate of the operation is improved. Secondly, the guiding component 30 can better support the guiding component 10, so that the defect of damage to the urethral mucosa of the patient caused by sliding the guide wire out of the catheter can be avoided.

In a preferred embodiment of the present utility model, referring to fig. 2, 3 and 4, the sidewall 111 of the drainage tube 11 is provided with a mounting groove 113. The indwelling balloon 21 is fixedly mounted in the mounting groove 113. When the indwelling balloon 21 is not inflated, the sidewall of the indwelling balloon 21 is not higher than the sidewall 111 of the drainage tube 11. By such arrangement, a physician can easily insert the baffle assembly 10 into the patient's urethra while minimizing the pain of the patient. When the indwelling balloon 21 is inflated through the inflation tube 22, the indwelling balloon 21 is inflated, and the side wall of the indwelling balloon 21 is higher than the side wall 111 of the drainage tube 11 at this time, so that the air guide assembly 10 is fixed and indwelled in the bladder by the inflated indwelling balloon 21.
