AI Technical Summary
Technical Problem
Existing urinary catheters are prone to retraction during use, are inconvenient to operate, and make it difficult to protect patient privacy in public places.
Method used
A novel catheterization device has been designed, comprising a tube body, a guide tube, and a limiting ring. The limiting ring engages with the inclined surface of the catheter to enable unidirectional movement of the catheter, and the catheter is concealed by the tube body to protect patient privacy.
Benefits of technology
It achieves convenient operation and privacy protection of urinary catheters, making it convenient for use in public places and maintaining hygiene and operating length during the catheterization process.

Abstract
The utility model discloses a novel urethral catheterization device which is characterized in that a urethral catheter is arranged in a guide tube, and the urethral catheter is in interference fit with the guide tube; a limiting cavity is formed in the other side of the catheter body, a limiting ring is arranged in the limiting cavity, one side of the catheter is installed on the inner side of the limiting ring, a non-return piece is arranged on one side of the limiting cavity, a first limiting piece matched with the limiting ring is arranged on the other side of the limiting cavity, and an inclined face matched with the limiting ring is arranged on one side of the non-return piece. When the guide pipe is pulled out towards one side, the catheter and the limiting ring are driven to move towards the non-return piece, under the action of the inclined face, the catheter deforms and is clamped, after clamping, the catheter and the guide pipe move relatively, and the catheter does not continue to move towards one side; when the guide pipe is pushed to the other side, after the limiting ring is separated from the inclined plane, the catheter is restored to the original shape and moves relative to the limiting ring, the catheter is pushed out under driving of the guide pipe, and one-way movement of the guide pipe is achieved; and the catheter can be conveniently pushed out and inserted into the urethra.
