Description

Technical Field

[0001] This invention relates to the field of nerve electrical stimulator technology, specifically a portable nerve electrical stimulator for relieving postoperative pain after kidney transplantation. Background Technology

[0002] Kidney transplantation is an important treatment for patients with end-stage renal disease, but postoperative pain is a common and critical issue affecting patient recovery—it not only reduces patient comfort and delays activity and recovery, but may also increase the risk of complications. Currently, postoperative analgesia largely relies on medication, but this has limitations such as drug tolerance and side effects (e.g., gastrointestinal irritation, respiratory depression). Especially for kidney transplant patients in an immunosuppressed state, drug selection and use require greater caution.

[0003] Neurostimulation, as a non-pharmacological analgesia method, blocks pain transmission by stimulating peripheral nerves with specific frequency electrical signals. It boasts advantages such as being non-invasive and having few side effects. However, existing neurostimulation devices are mostly fixed models, resulting in problems such as large size, inconvenience in fitting with hospital beds, easy tangling and messiness of electrode leads, and insufficient device protection. These issues make it difficult to meet the needs of bedside portability and stable use for patients after kidney transplantation. Therefore, developing a dedicated neurostimulation device that is bed-compatible, portable, detachable, and combines protective and wire management functions is of great significance for improving post-kidney transplant analgesia and the patient's recovery experience. Summary of the Invention

[0004] The purpose of this invention is to provide a portable nerve electrical stimulator for relieving post-kidney transplant pain, thereby addressing the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: a portable nerve electrical stimulator for relieving postoperative pain after kidney transplantation, comprising a device body with a hollow cavity structure;

[0006] An adjustment component is fixedly connected to the top end face of the main body of the device at the center position;

[0007] A portable disassembly and installation mechanism is provided. The end of the adjustment component away from the main body of the device is detachably connected to the portable disassembly and installation mechanism. The portable disassembly and installation mechanism includes a horizontally arranged mounting base. The top end face of the mounting base is fitted with the main body of the electrotherapy device. Vertically arranged transverse blocks are fixedly connected to both sides of the top end face of the mounting base on the main body of the electrotherapy device.

[0008] The protective mechanism has at least two sets of protective mechanisms evenly distributed and fixedly connected to the outer side wall of the portable disassembly and installation mechanism.

[0009] Preferably, the bottom end face of the electrotherapy device has four corners integrally formed with protruding positioning blocks. Corresponding to the position of the positioning blocks, the top end face of the mounting base is provided with positioning grooves that are adapted to the positioning blocks. Each positioning block is embedded and snapped into the corresponding positioning groove.

[0010] Preferably, magnetic blocks are fixedly connected to both sides of the main body of the electrotherapy device at the positions corresponding to the transverse blocks. Corresponding to the positions of the magnetic blocks, a magnetic groove adapted to the magnetic blocks is opened on the side wall of the transverse block near the main body of the electrotherapy device. The magnetic blocks are embedded and adsorbed into the magnetic grooves.

[0011] Preferably, the protective mechanism includes a vertically upward extending rotating column, one bottom end of which is fixedly connected to the outer side wall of the portable disassembly and installation mechanism, and a 360° rotatable support is sleeved and rotatably connected to the top outer side wall of the rotating column. The outer side wall of the 360° rotatable support is integrally formed with an outwardly extending connecting ear, and a cable management clamp is fixedly connected to the connecting ear.

[0012] Preferably, the outer wall of the cable management clamp has a number of connecting protrusions evenly distributed at the end away from the 360° rotatable support. Each connecting protrusion is fixedly connected to an elastic element, and the ends of all the elastic elements away from the cable management clamp are fixedly connected to an arc-shaped anti-collision plate.

[0013] Preferably, one bottom end of the adjustment component is fastened to the center area of ​​the top end face of the device body by bolts, and the top end of the adjustment component is detachably connected to the center position of the bottom end face of the mounting base of the portable disassembly and installation mechanism by a flange.

[0014] Preferably, the main body of the electrotherapy device achieves initial positioning through the snap-fit ​​of the positioning blocks at the four corners of its bottom end face with the corresponding positioning grooves on the top end face of the mounting base. At the same time, the main body of the electrotherapy device achieves stable connection with the mounting base through the magnetic engagement of the magnetic blocks on both sides with the magnetic grooves of the transverse blocks on the mounting base.

[0015] Preferably, an annular bearing is provided between the inner wall of the 360° rotatable support and the outer wall of the rotating column. The 360° rotatable support is sleeved on the outer side of the rotating column through the annular bearing and can rotate 360 ​​degrees around the axis of the rotating column. The cable management clamp is fixedly connected to the connecting lug on the outer wall of the 360° rotatable support by welding.

[0016] Preferably, one end of the elastic element is fastened to the connecting protrusion on the outer wall of the cable management clamp by a screw, and the other end of the elastic element is fixedly connected to the inner wall of the anti-collision plate by an adhesive method, and several elastic elements are evenly distributed between the cable management clamp and the anti-collision plate.

[0017] Preferably, one end of the bottom of the rotating column of the protective mechanism is vertically welded to the outer wall of the electrotherapy device body of the portable disassembly and installation mechanism, and the axis of the rotating column is perpendicular to the outer wall of the electrotherapy device body.

[0018] The beneficial effects of this application are:

[0019] This application provides a portable nerve electrical stimulator for relieving post-kidney transplant pain. Through a fixed connection between the main body and the adjustment components, a detachable connection between the adjustment components and the portable disassembly and installation mechanism, and a circumferentially uniform connection between the portable disassembly and installation mechanism and the protective mechanism, the assembly of each component is stable and rationally arranged. This ensures both the overall structural strength of the device and facilitates independent maintenance of each component. The positioning block at the bottom of the electrotherapy device and the positioning groove on the mounting base engage in a one-to-one correspondence, achieving rapid and accurate initial positioning of the electrotherapy device, preventing misalignment during assembly and improving assembly efficiency.

[0020] By aligning the cross-section on the mounting base with the magnetic blocks on the main body of the electrotherapy device, and by embedding and adsorbing the magnetic blocks into the magnetic grooves on the cross-section, the connection stability between the main body of the electrotherapy device and the mounting base is further strengthened. This also ensures ease of assembly and disassembly, enhancing the device's portability and flexibility. Through the fixed connection between the rotating column and the portable disassembly and installation mechanism, the rotatable connection between the 360° rotatable support and the rotating column, and the fixed connection between the cable management clamp and the earpiece connected to the 360° rotatable support, the cable management clamp can be flexibly adjusted 360 degrees around the rotating column to adapt to different cable management needs in various usage scenarios, improving the convenience of cable management.

[0021] By connecting the protrusions on the outer wall of the cable management clamp to the elastic element and the elastic element to the arc-shaped anti-collision plate, and by evenly distributing the elastic element between the cable management clamp and the anti-collision plate, a comprehensive buffer protection is formed on the outside of the device, reducing the damage to the internal components from collisions and ensuring the structural integrity of the cable management area. The bottom of the adjustment component is fastened to the center of the top end face of the device body with bolts, and the top of the adjustment component is detachably connected to the center of the bottom end face of the mounting base with a flange, so that the adjustment component is firmly connected and easy to install and disassemble, can stably transmit the adjustment force, and ensure the adjustment accuracy and operational stability of the device.

[0022] Initial positioning is achieved through the snap-fit ​​between the positioning block and the positioning groove, followed by reinforcement through the adsorption of the magnetic assembly block and the magnetic groove. This dual positioning and fixing structure works synergistically, improving the assembly stability of the electrotherapy device and the mounting base while reducing disassembly difficulty, meeting the requirements for reliable component connections during portable movement. The ring bearing between the 360° rotatable support and the rotating column, along with the welding and fixing of the cable management clamp to the connecting earpiece, ensures smooth and seamless rotation of the 360° rotatable support. Simultaneously, the cable management clamp is securely connected and unlikely to detach, guaranteeing stable cable management functionality.

[0023] The elastic element is securely connected to the cable management clamp at one end by a screw with a protruding screw, and the other end is bonded to the inner wall of the anti-collision plate. This ensures a reliable connection of the elastic element, fully utilizing its buffering and shock-absorbing function. It also facilitates the individual replacement of the elastic element or the anti-collision plate, reducing maintenance costs. The bottom of the rotating column is vertically welded to the outer wall of the electrotherapy device body, and the axis of the rotating column remains perpendicular to the outer wall of the electrotherapy device body. This ensures uniform force distribution on the rotating column, guarantees the stability of the 360° rotatable support during rotation, avoids adjustment jamming due to installation tilt, and improves the reliability of the protective mechanism.

The magnetic blocks 36 are embedded and adsorbed into the magnetic grooves 37.

[0041] The protective mechanism 4 includes a vertically upward extending rotating column 41. One bottom end of the rotating column 41 is fixedly connected to the outer side wall of the portable disassembly and installation mechanism 3. The top outer side wall of the rotating column 41 is fitted with and rotatably connected to a 360° rotatable support 42. The outer side wall of the 360° rotatable support 42 is integrally formed with an outwardly extending connecting ear. A cable management clamp 43 is fixedly connected to the connecting ear.

[0042] The outer side wall of the cable management clamp 43 has several connecting protrusions evenly distributed at the end away from the 360° rotatable support 42. Each connecting protrusion is fixedly connected to an elastic element 44. All the elastic elements 44 are fixedly connected to an arc-shaped anti-collision plate 45 at the end away from the cable management clamp 43.

[0043] One end of the adjustment component 2 is fastened to the center area of ​​the top end face of the device body 1 by bolts. The top end of the adjustment component 2 is detachably connected to the center position of the bottom end face of the mounting base 31 of the portable disassembly and installation mechanism 3 by a flange.

[0044] The main body 32 of the electrotherapy device is initially positioned by the snap-fit ​​of the positioning blocks 33 at the four corners of its bottom end face with the corresponding positioning grooves 34 on the top end face of the mounting base 31. At the same time, the main body 32 of the electrotherapy device is stably connected to the mounting base 31 by the magnetic snap-fit ​​of the magnetic splicing blocks 36 on both sides with the magnetic splicing grooves 37 on the transverse cut blocks 35 on the mounting base 31.

[0045] A ring bearing is provided between the inner wall of the 360° rotatable support 42 and the outer wall of the rotating column 41. The 360° rotatable support 42 is sleeved on the outer side of the rotating column 41 through the ring bearing and can rotate 360 ​​degrees around the axis of the rotating column 41. The cable management clamp 43 is fixedly connected to the connecting lug on the outer wall of the 360° rotatable support 42 by welding.

[0046] One end of the elastic element 44 is fastened to the connecting protrusion on the outer wall of the cable management clamp 43 by a screw, and the other end of the elastic element 44 is fixedly connected to the inner wall of the anti-collision plate 45 by an adhesive method. Several elastic elements 44 are evenly distributed between the cable management clamp 43 and the anti-collision plate 45.

[0047] The bottom end of the rotating column 41 of the protective mechanism 4 is vertically welded to the outer wall of the electrotherapy device body 32 of the portable disassembly and installation mechanism 3, and the axis of the rotating column 41 is perpendicular to the outer wall of the electrotherapy device body 32.

[0048] This embodiment provides a portable nerve electrical stimulator for relieving post-kidney transplant pain, specifically including a device body 1, an adjustment component 2, a portable disassembly and installation mechanism 3, and a protective mechanism 4. The portable disassembly and installation mechanism 3 consists of a mounting base 31, an electrotherapy device body 32, a positioning block 33, a positioning groove 34, a cross-section block 35, a magnetic assembly block 36, and a magnetic assembly groove 37. The protective mechanism 4 consists of a rotating column 41, a 360° rotatable support 42, a cable management clamp 43, an elastic element 44, and a crash plate 45.

[0049] 2. During assembly, first fasten the bottom of the adjustment component 2 to the center area of ​​the top end face of the device body 1 with bolts, and then detachably connect the top of the adjustment component 2 to the center of the bottom end face of the mounting base 31 through the flange to complete the connection and fixation between the device body 1 and the portable disassembly and installation mechanism 3.

[0050] 3. Then, the positioning blocks 33 at the four corners of the bottom of the electrotherapy device body 32 are embedded into the positioning grooves 34 at the top of the mounting base 31 one by one to achieve initial positioning. At the same time, the magnetic blocks 36 on both sides of the electrotherapy device body 32 are embedded into the magnetic grooves 37 of the transverse blocks 35 on the mounting base 31, and the electrotherapy device body 32 and the mounting base 31 are stably assembled through magnetic attraction.

[0051] 4. Finally, vertically weld the bottom of the rotating column 41 of the protective mechanism 4 to the outer wall of the electrotherapy device body 32. Install a 360° rotatable support 42 with a ring bearing on the outside of the rotating column 41, and weld the cable management clamp 43 to the connecting ear of the 360° rotatable support 42. Then, fix one end of the elastic element 44 to the connecting protrusion of the cable management clamp 43 with screws, and adhere the other end to the inner wall of the arc-shaped anti-collision plate 45, completing the assembly of the entire device.

[0052] Working Principle: Overall Assembly Principle: The overall assembly process of this device relies on the collaborative implementation of multi-dimensional and multi-method connection structures. Through the scientific combination and synergistic effect of various connection methods such as bolts, flanges, snap-fit, magnetic attraction, and welding, precise docking and stable connection between components are ensured. Specifically, the main body 1 and the adjusting component 2 are connected by bolts. Bolt connections have the advantages of high connection strength, convenient assembly and disassembly, and uniform force distribution, which can firmly fix the adjusting component 2 in the central area of ​​the top end face of the main body 1, avoiding loosening or displacement after assembly. The adjusting component 2 and the mounting base 31 are connected by a detachable flange. The flange connection is locked by multiple evenly distributed bolts, which not only further improves the stability of the connection, but also ensures the balance of force transmission when the adjusting component 2 is applied, avoiding excessive local stress that could damage the component. The electrotherapy device body 32 and the mounting base 31 are connected using a dual method combining snap-fit ​​and magnetic attraction, achieving both rapid and precise positioning and ensuring connection stability. The protective mechanism 4 is welded to the electrotherapy device body 32. This welded connection is non-removable and has high strength, ensuring that the protective mechanism 4 remains stable throughout the device's use and effectively performs its protective function. Through the coordinated use of these multiple connection methods, the precise assembly and stable connection of all components of the device are achieved, comprehensively ensuring the integrity and stability of the overall device structure. At the same time, the ease of disassembly and assembly of each core functional component is taken into account, meeting the portable use needs of kidney transplant patients in scenarios such as carrying the device for movement and outings for follow-up examinations, thus improving the device's practical application adaptability.

[0053] 2. Portable Disassembly Principle: The portable disassembly function between the electrotherapy device body 32 and the mounting base 31 is achieved through a dual structure of snap-fit ​​positioning and magnetic fixation. This ensures the stability of the connection after assembly while reducing the difficulty of disassembly, fully meeting the needs of portable use. During the assembly stage, the positioning blocks 33 integrally formed at the four corners of the bottom of the electrotherapy device body 32 and the positioning grooves 34 correspondingly opened on the top end face of the mounting base 31 form a precise snap-fit ​​fit. The size of the positioning blocks 33 and the size of the positioning grooves 34 are perfectly matched, and the outer side wall of the positioning blocks 33 and the inner side wall of the positioning grooves 34 are tightly fitted. This allows for quick initial positioning of the electrotherapy device body 32 and the mounting base 31, avoiding any front-back or left-right offset during assembly and laying a precise positioning foundation for subsequent magnetic fixation. After initial positioning, the magnetic blocks 36 fixedly connected to both sides of the electrotherapy device body 32 and the magnetic grooves 37 opened on the inner side of the transverse block 35 on the mounting base 31 form an embedded adsorption fit. The magnetic blocks 36 are made of high-magnetic permanent magnet material, and the inner side wall of the magnetic grooves 37 is provided with a magnetic attraction layer with the opposite magnetic properties to those of the magnetic blocks 36. When the magnetic blocks 36 are fully embedded in the magnetic grooves 37, the electrotherapy device body 32 and the mounting base 31 are stably fixed by magnetic attraction, ensuring that the electrotherapy device body 32 will not loosen or fall off during movement and use. When disassembly is required, simply apply an external force perpendicular to the mounting base 31 to the electrotherapy device body 32. This external force can overcome the magnetic attraction between the magnetic blocks 36 and the magnetic grooves 37, causing the magnetic blocks 36 to detach from the magnetic grooves 37, and simultaneously causing the positioning block 33 to detach from the positioning groove 34, thereby quickly removing the electrotherapy device body 32 from the mounting base 31. This disassembly method requires no tools and is simple and convenient to operate. It makes it easy for users to clean, maintain or replace the main body 32 of the electrotherapy device, and also makes it easy for users to separate the main body 32 of the electrotherapy device from other components of the device and carry them separately. This reduces the overall volume during the carrying process and further improves the portability of the device, making it suitable for the disassembly and carrying needs of various usage scenarios such as home care and medical treatment for patients after kidney transplantation.

[0054] 3. Cable Management Adjustment Principle: The cable management adjustment function is achieved through the coordinated operation of the rotating column 41, the 360° rotatable support 42, and the cable management clamp 43. This allows for flexible adjustment of the cable management angle, effectively solving the problems of tangled and messy cables during device use, and improving ease of use and safety. Specifically, the rotating column 41 is vertically welded to the outer wall of the electrotherapy device body 32, with its axis strictly perpendicular to the outer wall of the electrotherapy device body 32. This ensures that the rotating column 41 is firmly installed and evenly stressed, providing a stable support foundation for subsequent rotational adjustments. A 360° rotatable support 42 is fitted onto the outer side of the rotating column 41, with a ring bearing between them. The ring bearing is a high-precision ball bearing, with its inner ring tightly fitted and fixedly connected to the outer wall of the rotating column 41, and its outer ring tightly fitted and fixedly connected to the inner wall of the 360° rotatable support 42. The ring bearing effectively reduces friction between the 360° rotatable support 42 and the rotating column 41, ensuring smooth rotation of the 360° rotatable support 42 around the axis of the rotating column 41 without jamming or shifting. A cable management clamp 43 is fixedly welded to the connecting ear on the outer wall of the 360° rotatable support 42. This welded connection ensures a secure connection between the cable management clamp 43 and the 360° rotatable support 42, preventing relative displacement during rotation and adjustment. During use, the treatment electrode wires and other wiring connected to the electrotherapy device body 32 can be placed inside the cable management clamp 43, which clamps and secures the wiring. When the direction of the sutures needs to be adjusted to suit different patient positions such as sitting, lying down, or treatment areas, simply push the suture clamp 43 by hand. This will cause the 360° rotatable support 42 to rotate 360 ​​degrees around the axis of the rotating column 41, thereby adjusting the direction of the sutures synchronously. This rotation adjustment method is flexible and convenient, allowing the sutures to be adjusted to the optimal placement angle according to actual usage needs. This effectively avoids problems such as poor contact and suture damage caused by tangling or twisting, while also reducing the restriction of sutures on patient movement and improving patient comfort during use. In addition, the clamping diameter of the suture clamp 43 can be adaptively adjusted according to the number and thickness of the sutures, further improving the adaptability of the suture management function and ensuring that sutures of different specifications can be stably organized and fixed.

[0055] 4. Protective Buffer Principle: The protective buffer function is achieved through the synergistic effect of the anti-collision plate 45 and the elastic element 44, effectively resisting damage to the core components inside the device from external collisions and ensuring the safety and stability of the device during use. The arc-shaped anti-collision plate 45 is made of high-strength, high-toughness engineering plastic material, which has good impact resistance and wear resistance, effectively resisting the impact of external forces during collisions and preventing itself from breaking. The anti-collision plate 45 is designed with an arc-shaped structure, which can disperse the concentrated force received during a collision to the entire surface of the anti-collision plate 45, thereby reducing the local stress intensity and improving the impact resistance of the anti-collision plate 45. The elastic element 44 uses high-quality cylindrical compression springs, and there are several of them, which are evenly distributed between the cable clamp 43 and the anti-collision plate 45. This even distribution ensures that when the anti-collision plate 45 is hit, each elastic element 44 can be evenly stressed, avoiding damage to the elastic element 44 or poor buffering effect due to excessive local stress. One end of the elastic element 44 is fastened to the connecting protrusion on the outer wall of the cable management clamp 43 by a screw, and the other end is fixed to the inner wall of the anti-collision plate 45 by a high-strength adhesive. Both connection methods have good connection reliability, ensuring that the elastic element 44 will not detach from the cable management clamp 43 or the anti-collision plate 45 during the extension and retraction process. When the device is subjected to an external collision, the outer arc-shaped anti-collision plate 45 first contacts the colliding object. The impact force generated by the collision will act on the anti-collision plate 45, which will then transmit the impact force to several elastic elements 44 connected to it. At this time, the elastic element 44 undergoes elastic deformation under pressure, absorbing a large amount of collision energy during the deformation process, thus achieving buffering and attenuation of the impact force. After the buffering effect of the elastic element 44, the impact force transmitted to the cable management clamp 43 and the internal electrotherapy device body 32 and other core components will be greatly reduced, thereby effectively preventing damage to the core components due to collision and ensuring the normal operation of the device. Furthermore, the elastic element 44 possesses excellent elastic recovery performance, quickly returning to its original state after a collision, ensuring the protective buffer mechanism continues to function effectively. This protective buffer structure is rationally designed, not only resisting impacts from different directions but also boasting advantages such as simple structure and convenient maintenance. When the elastic element 44 or the anti-collision plate 45 is damaged, it can be replaced individually without replacing the entire protective mechanism 4, effectively reducing maintenance costs.

[0056] 5. Adjustment Transmission Principle: The adjustment transmission function is achieved through the secure connection between the adjustment component 2 and the main body 1 of the device, as well as the portable disassembly and installation mechanism 3. This ensures that the adjustment force is stably and accurately transmitted to the main body 32 of the electrotherapy device, guaranteeing the accuracy and stability of the device's adjustment. The adjustment component 2, as the core component for force transmission, has two ends securely connected to the main body 1 and the mounting base 31, respectively. The bottom of the adjustment component 2 is fastened to the center area of ​​the top end face of the main body 1 by multiple evenly distributed bolts. The number of bolts is rationally set according to the size of the adjustment component 2 and the force requirements, ensuring that the connection can withstand the force generated during adjustment and preventing loosening or deformation. The top of the adjustment component 2 is detachably connected to the center of the bottom end face of the mounting base 31 via a flange. The connecting surface of the flange is precision machined to ensure coaxiality between the adjustment component 2 and the mounting base 31 after connection, preventing jamming or uneven force transmission during adjustment due to misalignment. During use, the user applies adjustment commands to the adjustment component 2 via the adjustment control unit on the main body 1. The transmission structure inside the adjustment component 2, such as the lead screw and gear set, converts the user's applied force into an adjustment force in a specific direction. Because the two ends of the adjustment component 2 are firmly connected to the main body 1 and the mounting base 31, and the connection points possess good stability and rigidity, the adjustment component 2 can stably and losslessly transmit the generated adjustment force to the mounting base 31. The mounting base 31 is stably connected to the electrotherapy device main body 32 via a dual connection method of snap-fit ​​and magnetic attraction, further transmitting the adjustment force to the electrotherapy device main body 32. This allows the electrotherapy device main body 32 to achieve precise adjustments in height, angle, etc., to adapt to the body shape, treatment area, and treatment position requirements of different patients. During the adjustment transmission process, the synergistic effect of the adjustment component 2 and the various connection points ensures the stable transmission of the adjustment force, avoiding force leakage or transmission deviation, thereby guaranteeing the accuracy and stability of the device's adjustment. Meanwhile, the transmission structure of the adjustment component 2 has good self-locking performance, which can maintain the current adjustment state after adjustment is completed and will not cause the adjustment position to shift due to external vibration or external force interference, further improving the reliability of the device during use and ensuring that patients after kidney transplantation can obtain stable and continuous pain relief treatment.
