Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a dialysis catheter with a protective structure, including a dialysis catheter body 1, a connector 2 connected to the right end of the dialysis catheter body 1, a first elastic sleeve 3 provided on the outside of the dialysis catheter body 1, an installation port provided on the top of the first elastic sleeve 3, and a retaining ring 4 fixedly installed in the installation port.
[0019] The position of the retaining ring 4 is used to accommodate the connection between the dialysis tube body 1 and the skin of the arm, preventing foreign objects from touching the connection.
[0020] A rigid ring 5 is fixedly installed on the top right side of the first elastic sleeve 3. A stud 6 is integrally formed on the top side wall of the dialysis tube body 1. A nut 7 is screwed through the first elastic sleeve 3 and the rigid ring 5 at the top of the stud 6.
[0021] Tightening nut 7 can increase the connection and fixation effect between the dialysis tube body 1 and the first elastic sleeve 3.
[0022] The right end of the first elastic sleeve 3 is integrally formed with a second elastic sleeve 8, which is located outside the connector 2.
[0023] The second elastic sleeve 8 can protect the position of the connector 2 and prevent external force from pulling the connector 2.
[0024] Specifically, the left end of the rigid ring 5 is fixedly connected to the right end of the outer wall of the retaining ring 4.
[0025] The left end of the rigid ring 5 is fixedly connected to the right end of the outer wall of the retaining ring 4 to enhance the integrated effect of the rigid ring 5 and the retaining ring 4.
[0026] Specifically, the inner wall of the second elastic sleeve 8 is provided with a receiving groove 9, and gauze can be placed in the receiving groove 9.
[0027] like Figure 1 As shown, when dialysis is not being performed, gauze can be inserted into the receiving groove 9 to protect the connector 2 from dust.
[0028] Specifically, a retaining net 10 is fixedly installed on the top of the retaining ring 4.
[0029] The mesh 10 can further enhance the protective effect of the retaining ring 4 without affecting breathability.
[0030] Specifically, the dialysis tube body 1 includes a flexible tube 11 and a rigid tube 12. The rigid tube 12 is located in the middle of the flexible tube 11, and the top of the side wall of the rigid tube 12 is integrally formed with the bottom of the stud 6.
[0031] If the entire dialysis tubing body 1 is made of tubing, tightening the nut 7 can easily flatten the tubing body 1 located below the nut 7.
[0032] Specifically, the nut 7 includes an internal threaded ring 13, which is screwed onto the stud 6. A pressure ring 14 is attached to the bottom of the internal threaded ring 13. Limiting posts 15 are integrally formed on both the left and right sides of the bottom of the pressure ring 14. Limiting grooves 16 are provided on both the left and right sides of the top of the hard ring 5. The side wall of the limiting post 15 slides against the inner side wall of the limiting groove 16.
[0033] The side wall of the limiting post 15 slides against the inner side wall of the limiting groove 16 to limit the movement trajectory of the pressure ring 14, so that the pressure ring 14 can only move up and down, and its bottom makes stable contact with the top of the hard ring 5.
[0034] If the internal threaded ring 13 rotates downwards directly, its bottom will rotate and rub against the top of the hard ring 5, reducing the service life of the hard ring 5.
[0035] Specifically, the outer side wall of the pressure ring 14 is provided with an annular groove 17, the outer side wall of the internal threaded ring 13 is integrally formed with a connecting ring 18, and the bottom of the inner side wall of the connecting ring 18 is integrally formed with a rotating ring 19, which is rotatably installed in the annular groove 17.
[0036] The rotating ring 19 can only rotate within the annular groove 17, but cannot move in other directions within the annular groove 17. It is used to make the internal threaded ring 13 and the pressure ring 14 rotate relative to each other. At the same time, when the internal threaded ring 13 moves upward, the rotating ring 19 can simultaneously drive the pressure ring 14 to move upward.
[0037] Working principle: The patient can put the first elastic sleeve 3 and the second elastic sleeve 8 on the arm, and place the connection between the dialysis tube body 1 and the arm skin inside the retaining ring 4, so as to avoid the patient accidentally pulling the wound and causing pain when asleep. When dialysis is performed, the second elastic sleeve 8 can be rolled up to expose the position of the connector 2. When not performing dialysis, gauze can be inserted into the receiving groove 9 to protect the connector 2 from dust.
