[0024] 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.
[0025] Please see Figures 1 to 6This utility model provides a technical solution: a comfortable lumbar support belt for nephrostomy drainage tubes, including a lumbar support belt 1, a buffer layer 2 provided on the inner side of the lumbar support belt 1, a first fitting belt 3 provided on the right front end of the lumbar support belt 1, and a second fitting belt 4 provided on the left front end of the lumbar support belt 1. A magnetic strip 5 is installed on the outer surface of the second fitting belt 4, and a combination connector 6 is provided on the outer surface of the magnetic strip 5. A U-shaped limiting frame 7 is installed at the center of the combination connector 6, and a buffer sleeve 8 is sleeved on the outer side of the U-shaped limiting frame 7. A support frame 9 is installed at the top of the rear end of the second fitting belt 4.
[0026] The lumbar support belt 1 is connected to the buffer layer 2, the first adhesive strip 3 and the second adhesive strip 4 by sewing. The buffer layer 2 is evenly distributed on the lumbar support belt 1. The lumbar support belt 1, the first adhesive strip 3 and the second adhesive strip 4 are made of elastic fabric, and the buffer layer 2 is made of memory foam. The outer side of the first adhesive strip 3 is provided with a hook and loop fastener, and the inner side of the second adhesive strip 4 is provided with a loop fastener. This facilitates the buffer layer 2 on the lumbar support belt 1 to provide cushioning and support, thereby improving wearing comfort. The second adhesive strip 4 is attached to the outside of the first adhesive strip 3, which is conducive to the subsequent positioning of the drainage tube.
[0027] The magnetic strip 5 is connected to the second adhesive tape 4 by stitching, and the magnetic strip 5 is connected to the combination connector 6 by magnetic adsorption. The magnetic strip 5 is fixed to the second adhesive tape 4. Subsequently, based on the magnetic adsorption between the magnetic strip 5 and the combination connector 6, they can be combined at different positions on the magnetic strip 5, and can be flexibly adjusted according to the length of the drainage tube.
[0028] The combination joint 6 and the U-shaped limit frame 7 are connected by threaded fixing, and the combination joint 6 is symmetrically distributed on the U-shaped limit frame 7. The U-shaped limit frame 7 and the buffer sleeve 8 are connected by sliding sleeve. The U-shaped limit frame 7 can be combined and fixed with the combination joint 6. The U-shaped limit frame 7 is installed in different positions according to the combination joint 6.
[0029] The inner wall of the support frame 9 has a storage groove 10 on its top surface and a limiting groove 11 on its bottom surface. A first magnetic block 12 is installed on the bottom surface of the inner wall of the support frame 9. A barrier plate 13 is installed inside the support frame 9. A connecting shaft 14 is installed through the top of the barrier plate 13, and the end of the connecting shaft 14 is connected to the support frame 9. The bottom of the barrier plate 13 is located inside the limiting groove 11, and a second magnetic block 15 is installed at the center of the bottom of the barrier plate 13. The barrier plate 13 is connected to the connecting shaft 14 by rotation, and the connecting shaft 14 is connected to the support frame 9 by embedding. The support frame 9 is connected to the second adhesive tape 4 by stitching. The length, width, and height of the barrier plate 13 are smaller than those of the storage groove 10. The barrier plate 13 can be rotated and adjusted by the connecting shaft 14 to facilitate the pressure and rotation of the barrier plate 13, which is conducive to the passage of the drainage tube for assembly.
[0030] The barrier plate 13 is connected to the second magnetic block 15 by embedding and fixing, and the bottom end of the barrier plate 13 is connected to the limiting square groove 11 by sliding connection. The second magnetic block 15 is connected to the first magnetic block 12 by magnetic attraction, and the first magnetic block 12 is connected to the support frame 9 by embedding and fixing. The barrier plate 13 can be stabilized after the drainage tube is limited by the magnetic attraction between the second magnetic block 15 and the first magnetic block 12, thus avoiding the swinging phenomenon.
[0031] Working principle: According to Figures 1 to 6First, the patient wears the lumbar support belt 1 and cushioning layer 2 by attaching them to the back of the waist using the first and second adhesive straps 3 and 4. Then, the first and second adhesive straps 3 and 4 are wrapped around the sides of the waist and brought to the front. The inner side of the second adhesive strap 4 is secured to the outer side of the first adhesive strap 3 via Velcro. Simultaneously, the support frame 9 on the second adhesive strap 4 is positioned in the area where the drainage tube is inserted. Adjustments are made so that the drainage tube, extending from the body, moves through the opening in the support frame 9 and into its interior. The drainage tube then compresses the barrier plate 13, causing the barrier plate 13 to rotate via the connecting shaft 14. The barrier plate 13 can then be rotated and stored in the storage slot 10, facilitating the movement of the drainage tube to the front end of the support frame 9. After the drainage tube separates from the barrier plate 13, the barrier plate 13 rotates and slides back to its original position due to its own weight. The barrier plate 13 drives the second magnetic block 15 to magnetically attract the first magnetic block 12, ensuring stable operation and preventing shaking. At the same time, the second fitting strap 4 and the waist support strap 1 cover the area where the drainage tube is inserted, improving protection. After the external drainage tube is initially limited by the support frame 9, it can be moved according to its length to fit between the magnetic strips 5 and the second fitting strap 4. The end of the drainage tube is equipped with a connector with a diameter larger than that of the drainage tube. This allows the buffer sleeve 8 and the U-shaped limiting frame 7 to drive the combined connector 6 to magnetically attract the magnetic strips 5. The buffer sleeve 8 and the U-shaped limiting frame 7 are also fitted over the outside of the drainage tube to restrict and fix it at different positions, preventing the drainage tube from swinging during subsequent patient rest or movement. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
