[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1-6As shown, an intermittent urinary catheter comprises a sleeve 1 and a core 2. The sleeve 1 is used to be inserted into the patient's urethra and is a hollow structure, with a cover body 3 fixed at the front end opening thereof, and a urinary catheter hole 4 is provided on the cover body 3. A disc 5 is rotatably provided in the sleeve 1 and is attached to the rear side of the cover body 3, specifically as follows: it also includes a rotating shaft 12, the front end of the rotating shaft 12 is fixed to the cover body 3, and the rear end thereof extends to the rear side of the cover body 3. The disc 5 is rotatably sleeved on the rear end of the rotating shaft 12. The disc 5 is provided with an opening and closing hole 6 which is aligned or staggered with the urinary catheter hole 4 after rotation. Preferably: the urinary catheter hole 4 is provided with two, and the two urinary catheter holes 4 are respectively arranged on both sides of the cover body 3. The opening and closing hole 6 is arranged one-to-one with the urinary catheter hole 4. By providing two urinary catheter holes 4, the drainage speed of urine can be guaranteed during catheterization. The tube core 2 is inserted into the tube sleeve 1 to guide the patient's urine out of the body, and the tube core 2 is rotatably arranged in the tube sleeve 1, and its rear end extends to the rear side of the tube core 2. Both sides of the front end of the tube core 2 are respectively provided with protrusions 7 that drive the disc 5 to rotate after the tube core 2 rotates. The rear side of the disc 5 is provided with a card slot 8 corresponding to the protrusion 7. After the tube core 2 is inserted into the tube sleeve 1, the protrusion 7 is inserted into the card slot 8, and then the rotation of the tube core 2 can drive the disc 5 to rotate.

[0032] like Figure 7-11 As shown, guide blocks 9 extending inward are respectively provided on both sides of the inner wall at the rear end of the tube sleeve 1, and guide grooves 10 corresponding to the guide blocks 9 are provided on the outer wall of the tube core 2 along its length direction. When the tube core 2 is inserted into the guide groove 10, the guide blocks 9 slide in the corresponding guide grooves 10, thereby ensuring that the protrusion 7 is smoothly inserted into the slot 8. A rotation groove 11 is provided at the rear end of the outer wall of the tube core 2 corresponding to the guide groove 10. The rotation groove 11 is arc-shaped and connected to the rear end of the guide groove 10 so that the guide block 9 can rotate when the tube core 2 rotates.

[0033] When intermittent catheterization is required, first insert the tube core 2 into the tube sleeve 1 according to the following method: align the guide groove 10 on the tube core 2 with the guide block 9 on the tube sleeve 1, ensure that the guide groove 10 is inserted into the guide block 9 when the tube core 2 is inserted into the tube sleeve 1, and the guide block 9 slides synchronously in the guide groove 10 during the insertion of the tube core 2 into the tube sleeve 1. Due to the positioning of the guide block 9 and the guide groove 10 before, it is ensured that after the tube core 2 is inserted into the tube sleeve 1, the protrusion 7 on the tube core 2 is just inserted into the groove 8 on the disc 5, and at this time, the urinary catheter hole 4 on the cover body 3 and the opening and closing hole 6 on the disc 5 are interlaced. Then, the tube core 2 is rotated in the tube sleeve 1, and the disc 5 rotates synchronously under the cooperation of the protrusion 7 and the groove 8. At the same time, the guide block 9 enters the rotating groove 10, and as the rotating groove 10 rotates, the guide block 9 reaches one end of the rotating groove 10, that is, the tube core 2 rotates to the right position, and the urinary catheter hole 4 on the cover body 3 is aligned with the opening and closing hole 6 on the disc 5. Under the limit of the guide block 9 by the rotating groove 10, it is ensured that the tube core 2 will not be separated from the tube sleeve 1. After the above operation is completed, the tube sleeve 1 together with the tube core 2 can be inserted into the patient's urethra to start intermittent catheterization. After the first catheterization is completed, the tube core 2 is rotated in the opposite direction. On the one hand, the catheter hole 4 on the cover body 3 and the opening and closing hole 6 on the disc 5 are staggered to close the front end opening of the tube sleeve 1. On the other hand, the rotating groove 10 synchronously rotates the guide block 9 to reach the other end of the rotating groove 10, that is, the position corresponding to the guide groove 10. The tube core 2 is rotated in the opposite direction again to the position, and then the tube core 2 is pulled out of the tube sleeve 1. In summary, after the tube core 2 is pulled out of the tube sleeve 1, the catheter hole 4 on the cover body 3 and the opening and closing hole 6 on the disc 5 are staggered to close the front end opening of the tube sleeve 1, so the patient's urine will not be collected into the tube sleeve 1 through the front end opening of the tube sleeve 1, which also avoids the urine in the tube sleeve 1 from flowing into the patient's body when the tube core 2 is inserted for catheterization next time.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
