Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figures 1-7 , a urinary catheterization device for urology provided by an embodiment of the present invention includes a urine storage tank 1 and a urinary catheter 2. One end of the urinary catheter 2 is set as an insertion end, and the other end is set as a connection end and is connected to the urine storage tank 1. It further includes: a connector 3, which is arranged at the upper end of the urine storage tank 1; an abutting member 4, which is arranged at the connection end of the urinary catheter 2. The connection end of the urinary catheter 2 extends out of one side of the abutting member 4 and is inserted into the connector 3; a clamping assembly, which is arranged on the abutting member 4 and is used for detachably limiting and fixing the abutting member 4 on the connector 3.

[0033] Specifically, the urine storage tank 1 is provided with legs at the bottom, which can be supported on a flat surface such as the ground, or installed on a clinical trolley, so that the urine storage tank 1 is stable and will not tip over and cause urine leakage; a discharge pipe is also provided at the bottom of the urine storage tank 1, and a valve is provided on the discharge pipe. When the urine storage tank 1 collects urine, the valve remains closed, and after the urine storage tank 1 collects a certain amount of urine, the valve can be opened to discharge the urine in a centralized manner; the urine storage tank 1 can be provided with a translucent shape, and a liquid level scale can be provided on the surface wall to facilitate observation of the urine collection situation. The catheter 2 is a flexible tube, the end of the insertion end of the catheter 2 is in a round and closed shape, and a hole is opened in the side wall to communicate the inside and the outside, so that the insertion end of the catheter 2 can be easily inserted into the urethra; an air bag is also arranged near the insertion end of the catheter 2, which is used to expand after entering the bladder to fix the insertion end of the catheter 2 in the bladder; a branch tube is arranged on the catheter 2, and the branch tube is connected to the air bag through a trachea buried in the catheter 2. Another valve is arranged at the tube mouth of the branch tube. When the valve is opened, a syringe can be connected through the branch tube to inject liquid into the air bag through the trachea to expand the air bag to form a fixing effect, or the liquid can be extracted to make the air bag deflate for subsequent removal. The connector 3 is used to connect the connecting end of the urinary catheter 2, and the caliber of the connector 3 matches the outer diameter of the urinary catheter 2; the abutment 4 is fixedly connected to the outer wall of the urinary catheter 2, preferably a ring-shaped protrusion structure, and the outer diameter is larger than the caliber of the connector 3; the connecting end of the urinary catheter 2 is inserted into the connector 3 until the abutment 4 abuts against the upper end of the connector 3, that is, the connecting end of the urinary catheter 2 extends out of the abutment 4 and is inserted into the connector 3. The clamping assembly fixes the abutment 4 on the connector 3, that is, the urinary catheter 2 is fixedly connected to the urine storage tank 1, and the detachable connection between the abutment 4 and the connector 3, that is, the urinary catheter 2 is conveniently removed from the urine storage tank 1, so as to facilitate the replacement of the urinary catheter 2 and the subsequent cleaning of the urine storage tank 1. In actual use of the present technical solution, when the urinary catheter 2 is connected to the urine storage tank 1, the connecting end of the urinary catheter 2 is inserted into the specified depth of the connector 3 so that the abutment 4 abuts against the connector 3, and then the abutment 4 and the connector 3 are limited and fixed by the snap-fit ​​assembly, thereby ensuring the connection between the urinary catheter 2 and the urine storage tank 1 and avoiding the generation of a connection gap. When the urinary catheter 2 needs to be replaced, the abutment 4 can be separated from the connector 3 with the help of the snap-fit ​​assembly, so that the urinary catheter 2 can be quickly pulled out of the connector 3 for easy disassembly, and then conveniently replaced according to the above-mentioned installation steps of the urinary catheter 2.

[0034] Compared with the prior art, a urological catheterization device proposed in an embodiment of the present invention can insert the connecting end of the catheter 2 into the connector 3 to a specified depth by setting a snap-on assembly, so that when the abutment 4 abuts against the connector 3, the abutment 4 and the connector 3 are limited and fixed, thereby ensuring the connection between the catheter 2 and the urine storage tank 1 and avoiding the generation of a connection gap. When the catheter 2 needs to be replaced, the abutment 4 can be separated from the connector 3 with the help of the snap-on assembly, so that the catheter 2 can be quickly pulled out from the connector 3, which is convenient for disassembly and improves the practicability of the device.

[0035] As a preferred technical solution of this embodiment, the clamping component includes two connecting ears 5 oppositely arranged on the abutting member 4. Two elastic pieces 6 are arranged between the two connecting ears 5. One of the connecting ears 5 is fixedly connected to one end of the two elastic pieces 6, and the other connecting ear 5 is movably penetrated by the other ends of the two elastic pieces 6. The two elastic pieces 6 are elastically bent and clamped on the outer wall of the connecting head 3. A convex body 7 is arranged on the outer wall of the connecting head 3 to limit the upper side of the elastic piece 6. Specifically, the connecting ear 5 is bent in the extending direction of the connecting end of the catheter 2, and the two connecting ears 5 are arranged on two opposite sides of the connecting head 3; the elastic piece 6 has bending elasticity. The two ends of the elastic piece 6 approach each other, so that the middle parts of the two elastic pieces 6 are bent away from each other, that is, the distance between the two elastic pieces 6 is enlarged, and it is approximately oval or circular; the maximum internal dimension after the two elastic pieces 6 are bent away is larger than the upper end outer diameter of the connecting head 3; preferably, the ends of the two elastic pieces 6 penetrating the connecting ear 5 can be connected together to form a button. Pressing the button can enlarge the distance between the two elastic pieces 6, and releasing the button can elastically restore the distance between the two elastic pieces 6 to shrink; the convex body 7 limits the elastic piece 6, that is, limits the height of the elastic piece 6 relative to the connecting head 3. At this time, the corresponding abutting member 4 abuts against the upper end of the connecting head 3, thereby closing the connecting head 3 and keeping the connecting end of the catheter 2 inserted into the connecting head 3 to communicate with the urine storage tank 1.

[0036] As a preferred technical solution of this embodiment, the distance between the two elastic pieces 6 when freely relaxed is smaller than the outer diameter of the catheter 2. Specifically, when disassembling the catheter 2 during actual use, pressing one end of the two elastic pieces 6 connected to form a button can make the two elastic pieces 6 move away from each other to enlarge the internal space, so as to meet the requirement that the convex body 7 can pass through between the two elastic pieces 6. Then, the catheter 2 can be slowly pulled out upward from the connecting head 3, and the abutting member 4 drives the connecting ear 5 to rise accordingly, so that the elastic piece 6 is separated from the connecting head 3 and gradually corresponds to the connecting end of the catheter 2. Release the button. After the elastic piece 6 is completely separated from the connecting head 3, the elastic piece 6 is straightened under the action of its own elastic force, that is, the two elastic pieces 6 approach each other to clamp the connecting end of the catheter 2, thereby closing the connecting end of the catheter 2 and avoiding continuous dripping of urine to pollute the environment when the catheter 2 is pulled out.

[0037] As a preferred technical solution of this embodiment, a chamfer is provided at the upper end of the convex body 7. Specifically, the chamfer facilitates the downward movement of the elastic piece 6 relative to the convex body 7, that is, facilitates the installation of the catheter 2. In actual use, first align the connection end of the catheter 2 with the connector 3, then press the button formed by the movable ends of the two elastic pieces 6 to bend the two elastic pieces 6 away from each other. Then, slowly insert the catheter 2 into the connector 3, and the two elastic pieces 6 can gradually fit over the outside of the connector 3 and can pass downward through the convex body 7 along the chamfer of the convex body 7. When the elastic piece 6 completely passes through the convex body 7, the abutting member 4 abuts against the upper end of the connector 3. Release the button, and the elastic piece 6 can elastically recover to fit against the outer wall of the connector 3, thereby being limited to the lower side of the convex body 7 to complete the fixed installation of the catheter 2.

[0038] In another embodiment proposed by the present invention, a ventilation pipe 8 is provided at the upper end of the urine storage tank 1. An electric fan 9 is fixedly installed in the ventilation pipe 8, and a purification screen 10 is provided at the upper end of the ventilation pipe 8. Specifically, the ventilation pipe 8 is provided at an eccentric position at the upper end of the urine storage tank 1; the electric fan 9 includes a drive motor and a fan blade connected to the output end of the drive motor. The drive motor has a function of switching between forward and reverse rotations, so that the electric fan 9 generates an exhaust air flow from bottom to top or an air suction flow from top to bottom in the ventilation pipe 8; the purification screen 10 is provided with ventilation holes to ensure that the upper end of the ventilation pipe 8 is communicated with the outside; the purification screen 10 is filled with materials such as activated carbon, which can be used to purify the urine odor. In actual use of this technical solution, driven by the electric fan 9, an exhaust air flow from bottom to top is generated in the ventilation pipe 8, thereby creating a negative pressure in the urine storage tank 1 to ensure that the urine in the catheter 2 can enter the urine storage tank 1 as much as possible, and will not stay in the catheter 2, let alone urine reflux, ensuring hygienic safety; at the same time, the urine odor follows the exhaust air flow through the purification screen 10 for odor purification to avoid environmental pollution.

[0039] As a preferred technical solution of this embodiment, a liquid injection port 11 is provided at the upper end of the urine storage tank 1. The connector 3 is threadedly connected to the liquid injection port 11. Specifically, the liquid injection port 11 is used to facilitate the injection of cleaning liquid into the urine storage tank 1; the lower end of the connector 3 is provided as a cover body, and the inner side of the cover body and the outer wall of the liquid injection port 11 are provided with mutually matching threads. The connector 3 is detachably connected to the liquid injection port 11 through threaded connection; after the catheter 2 is removed and the urine in the urine storage tank 1 is drained, then remove the connector 3 from the liquid injection port 11, and it is convenient to add cleaning liquid into the urine storage tank 1 from the liquid injection port 11.

[0040] As a preferred technical solution of this embodiment, a stirring rod 12 is movably arranged in the urine storage tank 1. The electric fan 9 can be reversed to drive the stirring rod 12 to move through a linkage component. Specifically, the arrangement of the stirring rod 12 can move in the urine storage tank 1 to stir the cleaning liquid when the electric fan 9 is reversed, so as to better and thoroughly clean the inner wall of the urine storage tank 1. Further, one side of the stirring rod 12 is attached to the inner wall of the urine storage tank 1, so that the inner wall of the urine storage tank 1 can be scraped when moving to remove stubborn urine stains. In addition, the reverse rotation of the electric fan 9 forms a downward air suction flow in the air vent pipe 8, which can promote the entry of external air into the urine storage tank 1 to mix with the cleaning liquid, promote the generation of foam in the cleaning liquid, improve the cleaning effect, and the air flow entering through the air vent pipe 8 can flow towards the liquid injection port 11 and then be discharged, realizing the circulation of the air flow inside and outside the urine storage tank 1, which can help to thoroughly remove the odor in the urine storage tank 1.

[0041] As a preferred technical solution of this embodiment, the linkage component includes a gear 13 rotatably arranged at the lower end of the air vent pipe 8. The gear 13 is driven by the reverse rotation of the electric fan 9. A toothed ring 14 meshing with the gear 13 is rotatably arranged at the upper end inside the urine storage tank 1. The upper end of the stirring rod 12 is fixedly connected to the toothed ring 14. Specifically, when the electric fan 9 rotates in reverse, it drives the gear 13 to rotate. The gear 13 drives the toothed ring 14 to rotate, and the toothed ring 14 drives the stirring rod 12 to rotate along the inner wall of the urine storage tank 1, so as to stir the cleaning liquid and scrape and clean the inner wall of the urine storage tank 1.

[0042] As a preferred technical solution of this embodiment, the gear 13 is coaxially connected with a transmission shaft 15 rotatably arranged in the ventilation pipe 8. The motor shaft of the electric fan 9 extends to the lower end and is coaxially connected with the transmission shaft 15 through a one-way bearing 16. Specifically, a bracket is arranged in the ventilation pipe 8 to rotatably support the transmission shaft 15, and the bracket does not affect the up-and-down communication of the ventilation pipe 8. The setting of the one-way bearing 16 makes it impossible for the motor shaft of the electric fan 9 to drive the transmission shaft 15 to rotate when the electric fan 9 rotates forward, thereby avoiding the stirring rod 12 from stirring the urine. When the electric fan 9 rotates reversely, the motor shaft of the electric fan 9 drives the transmission shaft 15 to rotate through the one-way bearing 16. At this time, the stirring rod 12 stirs the cleaning liquid and scrapes and cleans the inner wall of the urine storage tank 1. In the actual use of this technical solution, when the urine storage tank 1 is normally collecting urine, the electric fan 9 rotates forward and does not drive the transmission shaft 15 to rotate. At this time, an upward airflow is generated in the ventilation pipe 8, thereby causing the urine storage tank 1 to exhaust air outward to generate negative pressure, ensuring that the urine in the catheter 2 enters the urine storage tank 1 as much as possible, and will not stay in the catheter 2, let alone urine reflux. At the same time, the urine odor follows the exhaust airflow through the purification screen 10 for odor purification. When the urine storage tank 1 is being cleaned, the liquid injection port 11 of the urine storage tank 1 is opened, and the cleaning liquid is added. Then the electric fan 9 rotates reversely, and the motor shaft of the electric fan 9 drives the transmission shaft 15 to rotate through the one-way bearing 16. The transmission shaft 15 drives the gear 13 to rotate, and the gear 13 drives the toothed ring 14 to rotate, thereby driving the stirring rod 12 to rotate. At this time, the stirring rod 12 stirs the cleaning liquid and scrapes and cleans the inner wall of the urine storage tank 1. At the same time, a downward suction airflow is generated in the ventilation pipe 8, which can promote the entry of external air into the urine storage tank 1 to mix with the cleaning liquid, promote the cleaning liquid to generate foam, improve the cleaning effect, and the airflow entering through the ventilation pipe 8 can flow to the liquid injection port 11 and then be discharged, realizing the circulation of the airflow inside and outside the urine storage tank 1, which can help to completely remove the odor in the urine storage tank 1.

[0043] As a preferred technical solution of this embodiment, the gear 13 is provided with a hollow structure. Specifically, the hollow setting of the gear 13 avoids blocking the connection between the lower end of the ventilation pipe 8 and the urine storage tank 1.
