DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Reference Figure 1 - Figure 3The utility model provides an embodiment: a kind of cystostomy tube, including drainage tube 1, drainage tube 1 is the pipeline for guiding liquid (such as urine) flow, drainage tube 1 one end is fixedly connected with catheter end 2, and catheter end 2 is the part that drainage tube 1 contacts with human urinary system, drainage tube 1 side wall is provided with flow guide pipe 9, and flow guide pipe 9 is used to guide urine and other liquids in drainage tube 1 to catheter container 11, and drainage tube 1 is internally provided with connecting assembly, and flow guide pipe 9 one end is provided with urine collection assembly, and urine collection assembly is used for urine centralized processing;

[0027] Connecting assembly includes sealing ring 8, sealing ring 8 is fixedly connected in the inside of drainage tube 1, and the outer wall of drainage tube 1 is slidably connected with sliding ring 3, and the inside of sliding ring 3 is provided with circular groove 4, in the sliding process of sliding ring 3, circular groove 4 will be displaced, when circular groove 4 moves to the position corresponding with conical groove 5, the activity space of slide bead 6 will be changed, the inside of drainage tube 1 is provided with a plurality of slide beads 6, and slide bead 6 is located in conical groove 5, and it is the key component for realizing flow guide pipe 9 detent and release detent, the inside of drainage tube 1 is provided with a plurality of conical grooves 5, and slide bead 6 is slidably connected in the inside of conical groove 5, and the inside of sliding ring 3 is provided with spring 7, and spring 7 is connected with sliding ring 3, in the sliding process of sliding ring 3, is extruded or released, and the outer wall of flow guide pipe 9 is provided with fixed ring 10, and flow guide pipe 9 is slidably connected in the inside of sealing ring 8.

[0028] Specifically, in the medical care operation, when the drainage tube 1 and the guide tube 9 need to be disassembled first, the medical staff needs to dial the sliding ring 3, which is located on the outer wall of the drainage tube 1. After being dialled by external force, the sliding ring 3 starts to slide on the outer wall of the drainage tube 1. In the process of sliding of the sliding ring 3, due to the spatial position relationship with the spring 7, the sliding ring 3 will further extrude the spring 7. After being extruded, the length of the spring 7 will be shortened accordingly, and at the same time, the sliding of the sliding ring 3 will also cause the displacement of the circular groove 4 inside it. With the movement of the circular groove 4, when it reaches the position of the tapered groove 5, it will change the spatial environment in the tapered groove 5. At this time, the sliding ball 6 located in the tapered groove 5 obtains a certain space for movement. Next, the medical staff pulls the guide tube 9, and the outer wall of the guide tube 9 is provided with a fixed ring 10. In the process of pulling the guide tube 9, the fixed ring 10 will move horizontally together with the guide tube 9. In the process of displacement, the fixed ring 10 will come into contact with the sliding ball 6 and exert a pushing force on it. Under the pushing of the fixed ring 10, the sliding ball 6 starts to slide inside the tapered groove 5. This sliding makes the clamping action of the sliding ball 6 on the guide tube 9 be released. Due to the disappearance of the clamping action of the sliding ball 6, the guide tube 9 is no longer restricted, and thus can be smoothly disassembled from the drainage tube 1. When it is necessary to reinstall the guide tube 9, in the process of inserting the guide tube 9 into the drainage tube 1, the sliding ball 6 will come into contact with the fixed ring 10 again. With the insertion of the guide tube 9, the sliding ball 6 will exert a clamping action on the fixed ring 10. Through this clamping, the guide tube 9 can be stably installed inside the drainage tube 1. And at the connection between the drainage tube 1 and the guide tube 9, the sealing ring 8 is used for sealing, to ensure the sealing of the connection and prevent urine leakage. In this way, the quick disassembly and assembly of the drainage tube 1 and the guide tube 9 is realized. This quick disassembly and assembly operation shortens the operation time of the medical staff and reduces the time of contact between urine and the wound and the surrounding skin in the disassembly and assembly process. Because long-term contact of urine with the wound and the surrounding skin can easily cause urinary system infection and wound infection, this quick disassembly and assembly operation also reduces the probability of urine polluting the wound and the surrounding skin, thereby effectively reducing the risk of urinary system infection and wound infection and protecting the health and safety of the patient.

[0029] Reference Figure 4 and Figure 5The urine collecting assembly comprises a urine guide container 11, which is a device for collecting urine. The urine guide container 11 is arranged at one end of the flow guide pipe 9. A fixing disc 12 is fixedly connected to the side wall of the urine guide container 11. A cross-shaped sliding groove 13 is formed in the inside of the fixing disc 12. The cross-shaped sliding groove 13 is located in the inside of the fixing disc 12 and provides a specific movement track for a sliding block 19. A connecting ring 15 is rotatably connected to one end of the flow guide pipe 9. The connecting ring 15 is located at the tail end of the flow guide pipe 9 and is a starting component for connecting or dismounting the urine guide container 11 and the flow guide pipe 9. A guide pipe 14 is fixedly connected to the inside of the connecting ring 15. The guide pipe 14 further guides the flow of urine. A connecting disc 16 is fixedly connected to the side wall of the connecting ring 15. A plurality of arc-shaped sliding grooves 17 are formed in the inside of the connecting disc 16. When the connecting disc 16 rotates, the arc-shaped sliding grooves 17 will have a centripetal displacement. This special movement mode provides a pushing force for a connecting shaft 20. A connecting frame 18 is fixedly connected to the side wall of the fixing disc 12. A plurality of sliding blocks 19 are slidably connected to the inside of the connecting frame 18. The side wall of each sliding block 19 is fixedly connected to the connecting shaft 20. The connecting shaft 20 is slidably connected to the inside of the arc-shaped sliding groove 17. The guide pipe 14 is slidably connected to the inside of the arc-shaped sliding groove 17. The guide pipe 14 is slidably connected to the inside of the fixing disc 12 and penetrates into the urine guide container 11.

[0030] Specifically, in the medical care scene, when the urine guide container 11 needs to be replaced, medical staff rotates the connecting ring 15, which is located at the tail end of the flow guide pipe 9. After being subjected to an external force, the connecting ring 15 will rotate around the axis of the flow guide pipe 9 at the tail end. In the rotating process of the connecting ring 15, due to the connecting relationship between the connecting ring 15 and the connecting disc 16, the connecting ring 15 will further drive the connecting disc 16 on the side wall to rotate synchronously. When the connecting disc 16 rotates, the structure in the inside of the connecting disc 16 will change accordingly. The arc-shaped sliding groove 17 is arranged in the inside of the connecting disc 16. In the rotating process, the connecting disc 16 will drive the arc-shaped sliding groove 17 to have a centripetal displacement. The connecting shaft 20 is located in the inside of the arc-shaped sliding groove 17. When the arc-shaped sliding groove 17 has a centripetal displacement, the connecting shaft 20 will be subjected to a pushing force from the arc-shaped sliding groove 17. After being subjected to the pushing force, the connecting shaft 20 will further drive a plurality of sliding blocks 19 to move. The sliding blocks 19 are located in the inside of the connecting frame 18. Under the driving of the connecting shaft 20, the sliding blocks 19 will slide in the inside of the connecting frame 18. The sliding-in or sliding-out of the sliding blocks 19 in the inside of the connecting frame 18 is very crucial because it will determine the position of the sliding blocks 19 in the cross-shaped sliding groove 13 in the inside of the fixing disc 12. In this way, the convenient connection and dismounting of the urine guide container 11 and the flow guide pipe 9 are realized. This convenient dismounting mode makes the replacement process of the urine guide container 11 more gentle and rapid. In the replacement process, medical staff can operate more carefully, reduces unnecessary irritation to patients caused by improper operation, and can maximize the reduction of irritation to patients, thereby improving the comfort of patients in the urine guide process and helping patients to better accept treatment and care.
