Description

Technical Field

[0001] This application relates to the field of medical device design, and further to a branching structure and rehabilitation equipment. Background Technology

[0002] Existing pelvic floor muscle rehabilitation devices often require the simultaneous connection of different types of electrode stimulation components during use. However, traditional solutions typically have multiple output ports directly installed on the device body to accommodate different electrode components. Due to the limited size of the rehabilitation device itself, the number of ports is restricted, resulting in insufficient expandability and inflexibility when multiple electrode components need to be connected simultaneously. Utility Model Content

[0013] The guide protrusion is a columnar structure, and the outer peripheral wall of the columnar structure is a smooth arc-shaped wall surface to match the contour of the guide recess.

[0014] In some embodiments, at least one of the connection ports of the second mating part is provided with three connection contact points, which are arranged in a triangular pattern along the circumference; at the same time, the connection port of the corresponding second connecting line is provided with a mating contact corresponding to the three connection contact points, so as to realize multi-point electrical connection during insertion.

[0015] And / or, the first connecting line is detachably connected to the output end of the pelvic floor muscle rehabilitation device, and the connection port of the first connecting line and the output end of the pelvic floor muscle rehabilitation device are respectively provided with a second limiting structure.

[0021] In some embodiments, the electrode patch is provided with at least three patch contacts, and the corresponding second connecting line is provided with a connector at the end away from the splitter body. The connector is provided with at least three contact points on one side.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Currently, pelvic floor muscle rehabilitation devices typically require the use of multiple electrode stimulation components, such as abdominal electrode patches and pelvic floor electrode probes. A common practice in existing rehabilitation devices is to directly install multiple output ports on the device body, with each electrode component connected to a corresponding port via an independent cable. Due to the limited size of the rehabilitation device itself, the number of ports that can be installed is restricted. When two or more electrode stimulation components need to be connected simultaneously, additional ports are often required, which not only occupies space but also increases the structural complexity and manufacturing cost of the device.

[0046] In one embodiment, refer to the appendix to the specification. Figure 1 See attached instruction manual Figure 1 The present application provides a splitting structure 1 for use in a pelvic floor muscle rehabilitation device 4, which includes a splitter body 10, a first connecting line 11 and at least two second connecting lines 12.

[0047] like Figure 2 and Figure 3As shown, the splitter body 10 has a first connecting side 101 and a second connecting side 102 located on different sides. A first docking part 13 is provided on the first connecting side 101, and at least two second docking parts 14 are provided on the second connecting side 102. The two ends of the first connecting line 11 are electrically connected to the output end 41 of the pelvic floor muscle rehabilitation instrument 4 and the first docking part 13, respectively. One end of each second connecting line 12 is used to dock with the corresponding electrode stimulation component 3, and the other end is detachably docked with the corresponding second docking part 14.

[0048] For further details, please refer to the appendix. Figure 4 and Figure 6 At least one second docking part 14 and its corresponding second connecting line 12 are provided with a first limiting structure 21 to limit the rotation of the second connecting line 12 relative to the second docking part 14 during the insertion process.

[0049] In this application, by setting docking parts on different sides of the splitter body 10, the signal of the rehabilitation instrument output terminal 41 can be transmitted to the splitter via the first connecting line 11, and then output to different electrode stimulation components 3 through multiple second connecting parts by the splitter structure 1. Thus, the extended connection of multiple electrode components can be realized with only a single output terminal 41 port on the rehabilitation instrument body. This can significantly reduce the number of ports on the rehabilitation instrument body and avoid the problems of complicated body structure and increased space occupation.

[0050] Furthermore, the second connecting line 12 and the second docking part 14 are detachably connected, allowing the electrode stimulation assembly 3 to be flexibly replaced as needed to meet the requirements of different scenarios. More importantly, the first limiting structure 21 introduced at the corresponding interface plays a clear guiding role during the insertion process, effectively preventing the connecting line from deflecting or being mis-inserted during insertion, improving the convenience of insertion and removal and the stability of the electrical connection, and significantly enhancing the reliability and service life of the overall system.

[0051] In practical applications, the aforementioned splitter structure 1 eliminates the need for multiple additional ports on the rehabilitation device itself, allowing for the connection of multiple components. This significantly reduces the space occupied by the internal layout of the device, ensuring a compact design and overall structural integrity. Furthermore, because the connecting cables are routed to different sides of the splitter body 10, their routing is more organized, facilitating easy identification and insertion / removal by operators, and enhancing safety and comfort during use.

[0052] Optionally, the splitter body 10 can adopt an integral molding structure, with the first connecting side 101 and the second connecting side 102 directly molded from the body material to improve structural strength and durability; alternatively, a modular assembly method can be adopted, with slots reserved on the body, and the first docking part 13 and the second docking part 14 installed in the corresponding positions through independent plug-in modules, which facilitates later replacement or maintenance.

[0053] In addition, the second connecting line 12 can be set to two, three or more depending on the number of electrode stimulation components 3. One end of each second connecting line 12 is electrically connected to the corresponding second docking part 14 through a plug-in structure, and the other end can be detachably docked with the electrode stimulation component 3 by using a plug or snap-fit ​​terminal.

[0054] In one embodiment, based on the content of the above embodiments, such as Figure 8 As shown, the splitter body 10 includes a main body 103, on which a first connecting side 101 and a second connecting side 102 are respectively provided on opposite sides. In other words, the first connecting side 101 and the second connecting side 102 are arranged opposite to each other along the length of the main body 103. The main body 103 preferably adopts an integrally formed structure, which is closed circumferentially to form a hollow tubular structure. The cross-section of the hollow tubular structure can be circular, elliptical, or other approximately closed contour shapes.

[0055] Between the hollow tubular structure and the first connecting side 101 and / or the second connecting side 102, there is an arc-shaped transition connection. In this way, the smooth curved surface transition design makes the overall outline of the splitter body 10 continuous and without obvious sharp corners. Therefore, a smooth stress distribution can be formed in the structure, avoiding stress concentration that may occur at sharp corners, thereby improving the overall mechanical strength and service life of the splitter structure 1.

[0056] Understandably, through the above-mentioned closed tubular structure design, the main body 103 is surrounded by a cable receiving cavity, which can provide an independent channel for the extension and reception of the first connecting line 11 and the second connecting line 12 while ensuring the overall structure is compact. This effectively stores and organizes the internal wires, reduces the risk of loose electrical connections caused by external pulling, and thus ensures the connection stability of the branch structure 1 during long-term use.

[0057] The inner wall of the cable receiving cavity can be coated with an insulating layer as needed to further enhance the electrical safety of the branch structure 1. The outer wall of the main body 103 can be made of plastic, elastomer or composite material depending on the application scenario, so as to ensure both strength and flexibility and durability.

[0058] It should also be noted that the wall thickness of the main body 103 can be adjusted according to the actual use environment. For example, it can be set as a thin-walled structure in scenarios where lightweighting is required, while it can be appropriately thickened in scenarios where mechanical strength needs to be improved. In this application, no specific limit is made on its wall thickness.

[0059] In one embodiment, such as Figure 4 and Figure 6 The first limiting structure 21 includes at least one guide recess 211 and at least one guide protrusion 212. The number of guide recesses 211 and guide protrusions 212 are correspondingly arranged so as to achieve mutual matching and limitation during insertion.

[0060] The second docking part 14 has guide protrusions 212 evenly or non-evenly arranged around its connection port, while the second connecting line 12 has corresponding guide recesses 211 around its connection port, or vice versa. This allows the guide protrusions 212 to enter the guide recesses 211 in a set direction when the second connecting line 12 is inserted into the second docking part 14, and to fit together after insertion. This effectively limits the insertion direction of the second connecting line 12 and circumferentially limits it after insertion to prevent the connection port from rotating.

[0061] Based on the above structure, the guide protrusion 212 and guide recess 211 can not only be designed as a single set, but also be set as multiple sets at the periphery as needed. Multiple guide structures (a general term for one guide protrusion 212 paired with one guide recess 211) can be distributed at equal or non-equal intervals at the periphery of the corresponding components to increase the limiting effect and error prevention characteristics.

[0062] Furthermore, the contours of the guide protrusion 212 and guide recess 211 can be designed with different geometric shapes, such as cylindrical, wedge-shaped, semi-circular, or irregular polygonal shapes. By combining different numbers and shapes of guide structures, each second mating part 14 and its corresponding second connecting line 12 have a unique mating method. In this way, even if there are multiple electrode stimulation components 3 and multiple second connecting lines 12, it can be ensured that each connecting line can only be inserted into its corresponding mating part, thereby avoiding mis-insertion problems.

[0063] Through the above design, by setting multiple guide structures of different shapes, the uniqueness of the connection can be enhanced while maintaining the basic limiting function, and electrical connection abnormalities caused by incorrect plugging can be prevented, thereby improving the safety and clinical applicability of the branch structure 1 in actual use.

[0064] In this application, the guide protrusion 212 is a columnar structure, and the peripheral wall of the columnar structure forms an arc-shaped smooth wall surface to reduce frictional resistance and improve guiding smoothness during the insertion process; the guide recess 211 is correspondingly set as a circular arc or arc groove mating structure, thereby achieving good correspondence and stability in geometry.

[0065] In one embodiment, each second docking part 14 has three connection contact points 141 at its connection port, such as... Figure 6 As shown, the contact point 141 has a probe-type structure and is arranged in a triangular pattern along the circumference of the second docking portion 14; simultaneously, as Figure 4 As shown, the corresponding second connecting line 12 has a mating contact 121 at the connection port that matches the three connecting contact points 141. Thus, during the insertion process, the probe-type connecting contact 141 and the mating contact 121 form corresponding contact to achieve multi-point electrical connection.

[0066] With this structural arrangement, the second docking part 14 can establish electrical contact at three different positions in the circumference when it is plugged into the corresponding connecting line. Compared with the traditional structure that only uses single-point or double-point contact, it not only effectively improves the stability of the connection, but also greatly improves the reliability and anti-interference ability of the electrical connection.

[0067] Specifically, the three-point contact structure creates a stable geometric support relationship, ensuring stable contact even under external disturbances, vibrations, or slight misalignments. This avoids poor contact caused by loosening of a single point. Furthermore, the parallel connection of multiple points along the current transmission path helps reduce the impact of single-point contact resistance on overall transmission performance, ensuring low impedance characteristics during electrical connection and further improving signal integrity and transmission efficiency.

[0068] Based on the above scheme, in specific implementation, the probe-type connection contact 141 can adopt an elastic telescopic structure, allowing it to deform appropriately under force during insertion, thereby ensuring tight contact with the corresponding mating contact 121. Simultaneously, it can automatically reset upon removal, facilitating repeated insertion and removal operations. To further improve durability, the contact material can be a metal material with excellent conductivity and a certain degree of elasticity, such as gold-plated copper alloy or silver-plated beryllium copper, to balance conductivity and wear resistance.

[0069] Meanwhile, the port that mates with contact 121 can be designed as a recessed or spring-loaded structure to provide a larger contact area and a stronger locking effect when in contact with probe-type connection contact 141, thereby further improving the overall reliability of the electrical connection.

[0070] In one embodiment, the first connecting line 11 is detachably connected to the output end 41 of the pelvic floor muscle rehabilitation device 4, so that it can be quickly disassembled and assembled as needed during daily use, maintenance or replacement of the device, thereby improving the overall ease of use of the device.

[0071] In addition, refer to the appendix Figure 5 and Figure 7 The connection port of the first connecting line 11 and the output end 41 of the pelvic floor muscle rehabilitation instrument 4 are respectively provided with a second limiting structure 22. The second limiting structure 22 is consistent with the design concept of the aforementioned first limiting structure 21. Its purpose is to form a precise positioning and error prevention function during the insertion process, thereby effectively avoiding poor contact caused by the operator's incorrect insertion direction or angle deviation.

[0072] Specifically, the connection port of the first connecting line 11 can be provided with a guide recess 221 (similar to the guide recess 211 of the first limiting structure 21), while the corresponding output end 41 of the pelvic floor muscle rehabilitation instrument 4 is provided with a guide protrusion 222 (similar to the guide protrusion 212 of the first limiting structure 21). During the insertion process, the two form a reliable guiding and limiting effect through the mutual cooperation of the concave and convex structures.

[0073] With this structural arrangement, the connection port can only be successfully inserted when the guide protrusion 222 and the guide recess 221 are correctly aligned, thus achieving a foolproof design and avoiding potential electrical performance hazards caused by incorrect insertion. Furthermore, the shape and quantity design of the guide protrusion 222 and the guide recess 221 in the second limiting structure 22 can be referenced from the design of the first limiting structure 21 above, and will not be repeated here.

[0074] In summary, the combined use of the first limiting structure 21 and the second limiting structure 22 in this application significantly reduces the possibility of misoperation, and in particular, ensures the safety and stability of the use process in the field of medical devices, ensuring that the rehabilitation device can operate reliably in clinical or home environments for a long time.

[0075] In one embodiment, refer to the appendix to the specification. Figure 1 According to another aspect of this application, this application further provides a rehabilitation device, including the above-mentioned wiring structure 1, pelvic floor muscle rehabilitation instrument 4, and electrode stimulation component 3, wherein the pelvic floor muscle rehabilitation instrument 4 is electrically connected to the corresponding electrode stimulation component 3 through the wiring structure 1.

[0076] It should be noted that the pelvic floor muscle rehabilitation device 4, as the core component of the rehabilitation equipment, typically includes a shell, a control module, an output terminal 41, and an operation interface. The control module is located inside the shell and is mainly used to generate electrical stimulation signals with specific parameters. These signals can be adjusted in terms of frequency, intensity, and waveform according to preset treatment modes to meet the rehabilitation needs of different patients. The output terminal 41 is located on the outer surface of the shell and is electrically connected to the signal output terminal 41 of the control module, used to transmit the electrical stimulation signal to the branching structure 1. The operation interface is located on the shell and is usually in the form of buttons or a touch screen, allowing users or medical personnel to select modes, adjust parameters, and perform start / stop operations, facilitating a personalized rehabilitation process.

[0077] Understandably, in rehabilitation equipment, the introduction of the branching structure 1 effectively solves the inconvenience that may arise from direct connection between the pelvic floor muscle rehabilitation device 4 and the electrode stimulation components 3. By adopting the branching structure 1 described in this application, an orderly and stable connection can be achieved between the pelvic floor muscle rehabilitation device 4 and multiple electrode stimulation components 3, and the setting of the limiting structure can effectively prevent incorrect insertion, thereby ensuring the correctness and safety of the electrical stimulation signal transmission.

[0078] Therefore, it can be seen that the rehabilitation equipment provided in this application, by adding a branching structure 1 between the pelvic floor muscle rehabilitation instrument 4 and the electrode stimulation component 3, makes the signal transmission process more reliable. At the same time, it has obvious convenience in the process of plugging, disassembling and replacing, which is conducive to flexible configuration under different treatment needs and usage scenarios, thereby improving the overall rehabilitation effect and patient compliance.

[0079] In one embodiment, such as Figure 1 and Figure 2 As shown, the electrode stimulation component 3 includes a first stimulation component 31 and a second stimulation component 32. The first stimulation component 31 includes an electrode patch 311 for direct attachment to the patient's body surface. During treatment, the electrode patch 311 forms a conductive contact with the patient's target area, thereby enabling the electrical signal output by the pelvic floor muscle rehabilitation device 4 to effectively act on the corresponding muscle group.

[0080] The second connecting line 12 is detachably connected to the electrode patch 311, which allows for quick replacement when the electrode patch 311 ages, loses adhesion, or needs to be replaced for different parts, without having to replace the entire electrode stimulation assembly 3. This significantly reduces usage costs and improves maintenance convenience.

[0081] A signal transmission element is provided between the second connecting line 12 and the electrode patch 311. The signal transmission element is used to ensure the stable transmission of electrical signals at the connection point, so that the electrical stimulation signal generated by the pelvic floor muscle rehabilitation device 4 can be transmitted to the patient's body surface in an efficient and stable manner, thereby improving the overall effect of rehabilitation treatment.

[0082] Understandably, the electrode stimulation component 3 in this application, through its detachable connection and cooperation with the signal transmission element, not only facilitates the replacement and maintenance of the electrode patch 311, but also improves the safety and reliability of the connection, providing flexible adaptability in different treatment scenarios. Therefore, this solution effectively extends the lifespan of the rehabilitation equipment and the patient's experience while ensuring the therapeutic effect. Generally, the signal transmission element can be set as a common metal sheet, conductive adhesive layer, or elastic conductor, etc. Of course, other components can also be used according to specific design requirements, and no specific limitations are made in this application.

[0083] Based on the above embodiments, in one embodiment, at least three patch contacts 3110 are provided on the electrode patch 311, and the patch contacts 3110 are distributed along a preset area of ​​the electrode patch 311 to form a stable electrical interface.

[0084] Correspondingly, such as Figure 8 As shown, the second connecting line 12 has a connector 122 at the end away from the splitter body 10. At least three contact points 1220 are provided on one side of the connector 122, and the number, position, and arrangement of the contact points 1220 correspond one-to-one with the number of patch contacts 3110. When the connector 122 is attached to the electrode patch 311, the contact points 1220 and patch contacts 3110 abut each other to form a stable electrical signal conduction connection. This multi-point abutment method significantly enhances the stability and anti-interference capability during electrical signal transmission compared to single-point or double-point contact structures, helping to avoid signal interruption or attenuation due to poor contact at individual contacts, thereby improving the reliability of signal transmission during rehabilitation therapy.

[0085] Furthermore, a snap-fit ​​or adsorption structure is provided between the connector 122 and the electrode patch 3110 to ensure the connection stability between the connector 122 and the electrode patch 311, thereby providing a more reliable electrical signal transmission path during rehabilitation treatment and ensuring the overall performance and therapeutic effect of the rehabilitation equipment. This design not only ensures a stable connection after the electrode patch 311 is attached to the human body surface, but also facilitates quick separation when replacement or disassembly is required, improving the ease of operation of the equipment.

[0086] In practical implementation, the electrode patch 311 and the connector 122 of the second connecting line 12 are fixed using a metal round-head snap-fit ​​structure. Specifically, the electrode patch 311 is provided with multiple round-head snap-fit ​​parts, which are made of conductive metal material and have a smooth surface to reduce frictional resistance during insertion and removal. Correspondingly, the connector 122 is provided with snap-fit ​​slots that are adapted to the round-head snap-fits. When the connector 122 is attached to the electrode patch 311, the round-head snap-fits can be pressed into the snap-fit ​​slots to form a snap-fit ​​connection, which can achieve both mechanical fixation and electrical connection, reducing the number of components and structural complexity.

[0087] In another implementation, the adsorption structure can be magnetic. Specifically, the connector 122 is provided with a magnetic material, and the corresponding area of ​​the electrode patch 311 is provided with an adsorbable metal sheet. When the two are close together, the connector 122 and the electrode patch 311 are tightly adsorbed together by magnetic force, thereby achieving electrical signal conduction while realizing physical adsorption.

[0088] In one embodiment, the electrode patch 311 has an adhesive layer on its surface away from the patch contact 3110. The adhesive layer is used to reliably fix the electrode patch 311 in a preset position. The adhesive layer is made of a material with a certain degree of adhesion, which can form a stable adhesion between the electrode patch 311 and the human body surface, so as to ensure the reliability of contact and the uniformity of stimulation during the transmission of electrical signals.

[0089] To improve the convenience of actual use, the adhesive layer is designed as a removable structure. After use, the electrode patch 311 can be peeled off from the preset position along with the adhesive layer, avoiding the decrease in comfort or skin burden caused by long-term adhesion.

[0090] In actual use, such as Figure 1 As shown, the adhesive layer is covered with a protective sheet 312 when not in use. The protective sheet 312 is peelable and adheres to the surface of the adhesive layer, thus preventing the surface of the adhesive layer from becoming contaminated with dust or losing its adhesiveness during transportation and storage. In use, simply remove the protective sheet 312 and then fix the electrode patch 311 to the target position using the adhesive layer. This ensures good adhesion of the adhesive layer before use, simplifies the operation process, and improves overall hygiene and convenience.

[0091] In another embodiment, the adhesive layer can be a disposable adhesive layer to ensure consistent adhesion with each use; alternatively, a reusable adhesive material, such as a medical-grade silicone adhesive layer, can be used, maintaining certain adhesive properties after multiple uses, thereby reducing usage costs. Depending on different clinical needs, users can choose either a disposable or reusable design, both of which can achieve the fixation and removal effects expected in this application.

[0092] Furthermore, in one embodiment, the electrode stimulation assembly 3 includes a second stimulation assembly 32, which includes a columnar docking body 321. A plurality of stimulation units 322 are continuously or intermittently arranged along the circumferential direction on the peripheral wall of the docking body 321. The stimulation units 322 are directly or indirectly electrically connected to corresponding second connecting lines 12, enabling electrical signals to be conducted to the stimulation units 322 during device operation, thereby forming effective electrode stimulation when they contact a preset location. The stimulation unit 322 can be an electrode sheet or electrode segment, as long as it has certain electrical conductivity.

[0093] Through this structural design, the second stimulation component 32 can perform in-depth rehabilitation training on the target muscle group, forming a stimulation pattern that works in conjunction with the electrode patch 311, thereby achieving a more comprehensive rehabilitation effect.

[0094] Understandably, the stimulation units 322 are distributed circumferentially along the docking body 321, which can ensure the coverage of electrical signals in different directions and can also be used for zoned stimulation according to actual needs, thereby improving the targetedness and comfort of rehabilitation.

[0095] Thus, when the second stimulation component 32 and the first stimulation component 31 are used together, they can simultaneously act on both the surface and deep target areas, thereby improving the overall effect of rehabilitation training and meeting the needs of multi-dimensional stimulation in clinical rehabilitation.

[0096] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
