Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a portable wireless pelvic floor rehabilitation therapy device. Background Technology

[0002] Pelvic floor rehabilitation therapy devices, also known as biofeedback devices, primarily collect spontaneous surface electromyography (sEMG) signals from the skin or pelvic floor cavity via surface electrodes. These signals are then denoised, amplified, filtered, and converted from digital to digital before analysis. Finally, simulated sound or visual signals are fed back to the patient, indicating normal and abnormal muscle activity. This allows patients to consciously control and correct abnormal psychological and physiological activities, engaging in active biofeedback training. Furthermore, biofeedback devices can be configured with different electrical stimulation parameters (stimulation intensity, stimulation frequency, pulse width, pulse frequency, rise / fall time, etc.) to provide passive electrical stimulation training to the patient's target muscles.

[0003] Currently, to facilitate individual users, there are some portable wireless biofeedback devices on the market. For example, patent document CN208958725U discloses a wireless pelvic floor training device, which integrates an electrical stimulation circuit module, a vibration module, a wireless communication module, and a main control module. It can combine multiple training methods such as electrical stimulation and vibration, and is small in size, making it convenient for users to carry at any time. Its disadvantages are that its fixed structure cannot adapt to the physiological differences of different users and the treatment needs of different stages of rehabilitation, and there is a risk of cross-infection when used by different people. Patent document CN218980251U discloses a pelvic floor muscle therapy device with detachable electrode heads. The electrode heads are connected to the treatment unit via a magnetic structure, allowing for direct replacement of electrode heads when used by different people, ensuring cleanliness and hygiene. Its disadvantages are that the connection between the electrode heads and the main unit is not secure, the electrode heads are disposable, and all components are located inside the treatment unit, resulting in a large treatment unit and insufficient portability. Utility Model Content

[0004] To overcome the aforementioned shortcomings of existing wireless pelvic floor training devices, the technical problem to be solved by this utility model is to provide a portable wireless pelvic floor rehabilitation therapy device with replaceable electrode housing components and a compact structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A portable wireless pelvic floor rehabilitation therapy device includes a main unit assembly and replaceable outer shell assemblies of various types. The main unit assembly includes a main shell and a circuit module. The main shell includes a housing and a guide post, which together form a cavity structure for accommodating the circuit module. A first spring pin electrically connected to the circuit module is provided on the guide post. The outer shell assembly includes an electrode housing and electrode plates protruding at least partially from the surface of the electrode housing. The electrode housing has a guide hole, and the contact end of the electrode plate is located in the guide hole. A matching docking mechanism is provided between the main shell and the electrode housing. The outer shell assembly is matched and inserted into the guide post through the guide hole. When the outer shell assembly and the main unit assembly are fixed by the docking mechanism, the first spring pin contacts the contact end of the electrode plate. The main unit assembly generates adjustable electrical pulses and transmits them to the electrode plates of the outer shell assembly through the first spring pin to electrically stimulate the pelvic floor muscles. It also collects electromyographic signals and physiological parameters such as pressure through the electrode plates, performs real-time analysis, display, and recording, and helps the user understand the functional status of the pelvic floor muscles. The main unit uses a T-shaped or inverted L-shaped housing, which can accommodate part of the circuit structure by using guide posts inserted into the electrode housing. This reduces the size of the housing located outside the electrode housing, thereby improving the convenience of storing, carrying and using the entire device.

[0006] The mating mechanism between the bottom of the main housing and the top of the electrode housing can adopt a threaded connection or a snap-fit ​​structure. Specifically, it includes an internal threaded sleeve or a slot on the main housing, and an external threaded post on the electrode housing that matches the internal threaded sleeve or a hook that matches the slot. Without loss of generality, the internal threaded sleeve and the external threaded post can be interchanged between the main housing and the electrode housing, and the hook and the slot can also be interchanged between the main housing and the electrode housing.

[0007] To ensure correct alignment of the main unit and outer casing during assembly, a receiving groove is provided on the top of the electrode outer casing, covering at least half the height of the main unit. The cooperation between the receiving groove and the main unit ensures correct contact between the spring pin and the electrode plate, while preventing relative rotation after insertion, thus ensuring stability during use. Furthermore, the receiving groove and the electrode outer casing are integrally molded, with no seams at the contact points with the body, preventing scratches or pinching injuries, and facilitating positioning during treatment and removal of the device after treatment.

[0008] After setting a receiving groove on the top of the electrode housing, the docking mechanism can adopt a snap-fit ​​structure set on the receiving groove and the main housing. When the lower half of the main housing mates with the receiving groove, the snap-fit ​​structure of the two engages and fixes each other. Alternatively, a magnetic attraction structure can be used, with a first magnetic attraction component set in the receiving groove and a second magnetic attraction component set on the main housing. The first and second magnetic attraction components are vertically aligned, and when the main housing mates with the receiving groove, the first and second magnetic attraction components are magnetically connected. The magnetic attraction structure is easy to assemble and disassemble, the connection is stable and reliable, and it is not prone to wear. Combined with the structure of the receiving groove covering the main housing, it can prevent the main housing components from falling off the housing components during use and removal of the equipment.

[0009] To prevent impact wear between the main casing and the receiving groove under magnetic attraction, multiple silicone plugs are provided around the bottom perimeter of the main casing. When the lower half of the main casing mates with the receiving groove, the silicone plugs abut against the inner wall of the receiving groove. After the adsorption stabilizes, the silicone plugs are pressed tightly between the main casing and the receiving groove, providing a sealing effect and preventing shaking between the main casing and the receiving groove.

[0010] To facilitate the installation of the internal circuit module, a top cover is provided on the top of the main housing, with a button on the top cover. The main housing is connected to the guide post by snap-fit, threaded connection, or integral injection molding. The circuit module includes a first PCB board, a second PCB board, a third PCB board, a fourth PCB board, and a battery. The first PCB board and the battery are located inside the main housing, the fourth PCB board is located at the bottom of the guide post, and the second and third PCB boards are located inside the guide post, with their upper and lower ends connected to the first and fourth PCB boards respectively. The first spring pin is fixed to the fourth PCB board. The entire circuit structure adopts a combination of multiple small circuit boards, which can make full use of the space in the main housing, making the overall structure more compact and conducive to the miniaturization of the device.

[0011] To enable wireless charging, a charging coil is housed within the receiving slot of the housing assembly. A second spring-loaded pin, connected to the battery, is located on the main housing. When the main housing mates with the receiving slot, the second spring-loaded pin contacts the energized end of the charging coil. Positioning the charging coil within the receiving slot of the housing assembly allows it to be closer to the housing surface, thus ensuring the stability of wireless charging.

[0012] To ensure stable operation of the first and second spring-loaded pins, silicone sleeves are fitted onto both pins. When the main unit is separated from the outer casing, the ends of the first and second spring-loaded pins are within the silicone sleeves. When the main unit is inserted and fixed to the outer casing, the silicone sleeves are compressed, exposing the ends of the first and second spring-loaded pins, which then contact the electrode plates and the charging coil terminals, respectively. The silicone sleeves guide and protect the spring-loaded pins, preventing oxidation or rust that may occur from prolonged exposure.

[0013] The beneficial effects of this utility model are: 1. The modular design that separates the main unit and the outer shell allows for free interchangeability between the same main unit and various models of treatment heads. A single device can accurately match the physiological characteristics of different users and the treatment needs of the same user at different stages of rehabilitation. Users no longer need to purchase multiple complete machines or an expensive set of dedicated systems to adapt to different sizes, which significantly improves the versatility of the device and greatly reduces the long-term use cost for users. 2. By making the treatment head, which comes into direct contact with the human body, an independent and replaceable module, the hygiene management process is greatly optimized. Users can easily clean and disinfect the outer shell components separately and thoroughly after use, or equip each user with a dedicated treatment head in multi-user scenarios (such as medical institutions), thereby fundamentally eliminating the risk of cross-infection and ensuring the safety and hygiene of use. 3. By separating the vulnerable outer casing components from the core main unit components, when only the outer casing is aged, worn, or damaged, only the individual treatment head module needs to be replaced, while the more valuable core main unit can continue to be used. This not only avoids the scrapping of the entire machine due to local problems, but also greatly extends the service life of the equipment and reduces electronic waste, reflecting higher resource utilization efficiency and environmental sustainability.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these terms are used to describe the relative positional relationships between components and are not specific references to the absolute positions of the components or the relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity such as "many," "multiple," or "several," these terms specifically refer to two or more.

[0018] like Figure 1 As shown, the portable wireless pelvic floor rehabilitation therapy device provided by this utility model includes a main unit assembly 1 and a replaceable outer shell assembly 2 of different types. The main unit assembly 1 includes a main unit shell and a circuit module. The main unit shell includes a main unit housing 11 and a guide post 12, which together form a cavity structure for accommodating the circuit module. The guide post 12 is provided with a first spring pin 13 electrically connected to the circuit module. The outer shell assembly 2 includes an electrode housing 21 and an electrode sheet 22 protruding at least partially from the surface of the electrode housing 21. The electrode housing 21 is provided with a guide hole 23, and the electrical connection end of the electrode sheet 22 is located at the bottom of the guide hole 23. A matching docking mechanism is provided between the main unit housing 11 and the electrode housing 21. The outer shell assembly 2 is matched and inserted into the guide post 12 through the guide hole 23. When the outer shell assembly 2 and the main unit assembly 1 are fixed by the docking mechanism, the first spring pin 13 contacts the electrical connection end of the electrode sheet 22.

[0019] The main unit 1, serving as the power supply and control center, primarily generates adjustable electrical pulses, which are transmitted to the electrode pads 22 of the outer shell 2 via the first spring pin 13 to electrically stimulate the pelvic floor muscles. Simultaneously, the electrode pads 22 collect electromyographic signals and physiological parameters such as pressure, performing real-time analysis, display, and recording to help users understand the functional status of their pelvic floor muscles. This invention features a wireless structure and therefore includes a built-in wireless communication module, enabling pairing with mobile apps and computer software via Bluetooth or short-range wireless modules. This supports remote monitoring, program downloads, and multi-scenario training. Due to the numerous internal circuit modules, traditional wireless pelvic floor rehabilitation devices are typically large, presenting drawbacks in terms of storage, portability, and use. This invention preferably features a T-shaped or inverted L-shaped main shell composed of the upper main shell 11 and the lower guide post 12. Figure 4 , Figure 7 As shown, the guide post 12 inserted into the electrode housing 21 can accommodate part of the circuit structure, thus reducing the size of the housing outside the electrode housing 21 and improving the convenience of storage, carrying, and use of the entire device. In addition, the guide post 12 of the main unit assembly 1 and the guide hole 23 of the housing assembly 2 are connected in a covering manner, which can improve the reliability of the connection between the main unit assembly 1 and the housing assembly 2 and avoid the situation where the main unit falls off during use and interrupts treatment.

[0020] The outer shell assembly 2, serving as the treatment head, directly contacts the pelvic floor muscles. Therefore, its surface must be smooth and rounded, and the electrode pads 22 must be tightly connected to the electrode shell 21 without any gaps. When manufacturing the outer shell assembly 2, if... Figure 5 As shown, the electrode pads 22 are first installed onto the inner electrode shell 213, and then the outer electrode shell 21 is injection molded in the mold. The electrode pads 22 are partially exposed on the surface of the outer electrode shell 21, thus avoiding gaps between the electrode pads 22 and the outer electrode shell 21, ensuring the stability of the electrode pad installation and its contact with the pelvic floor muscles. Generally, three electrode pads 22 are provided, located on different sides of the outer electrode shell 21. Correspondingly, three first spring pins 13 are also required, each contacting the corresponding electrical terminal of the electrode pad 22. Different types of shell assemblies 2 include different sizes and functions, but their internal guide holes 23 are all the same to ensure compatibility with the same main unit assembly 1. Different sizes refer to different outer diameters and lengths of the outer electrode shell 21, and different functions refer to functions such as electrofeedback, electrostimulation, or vibration. Users can choose the appropriate shell assembly 2 according to their own physiological characteristics and the needs of each stage of rehabilitation.

[0021] For the docking mechanism between the main housing 11 and the electrode housing 21, a threaded connection or a snap-fit ​​connection can be used for easy disassembly and assembly, such as... Figure 2As shown, an internally threaded sleeve 111 can be provided at the bottom of the main housing 11, and an externally threaded post 211 adapted to the internally threaded sleeve 111 can be provided at the top of the electrode housing 21. Ensure that when the externally threaded post 211 is fully screwed into the internally threaded sleeve 111, the electrode plate 22 contacts the corresponding first spring pin 13; alternatively... Figure 3 As shown, a slot 112 is provided at the bottom of the main housing 11, and a hook 212 adapted to the slot 112 is provided at the top of the electrode housing 21. When the hook 212 is aligned with the slot 112 and tightly engaged, the electrode plate 22 can contact the corresponding first spring pin 13. Without loss of generality, the inner threaded sleeve 111 and the outer threaded post 211 can be interchanged between the main housing 11 and the electrode housing 21, and the hook 212 and the slot 112 can also be interchanged between the main housing 11 and the electrode housing 21.

[0022] Considering that multiple first spring pins 13 must contact their corresponding different electrode plates 22, it is necessary to ensure the insertion orientation of the housing assembly 2 and the main unit assembly 1. A preferred embodiment of this invention is as follows: Figure 1 , Figure 6 As shown, the top of the electrode housing 21 is provided with a receiving groove 24. The inner contour of the receiving groove 24 matches the outer contour of the lower half of the main housing 11. That is, after the main unit assembly 1 and the housing assembly 2 are mated, the receiving groove 24 covers at least half the height of the main housing 11. In addition, the inner contour of the receiving groove 24 and the outer contour of the lower half of the main housing 11 can preferably be non-rotationally symmetrical. This ensures that the housing assembly 2 and the main unit assembly 1 have only one correct insertion method and avoids relative rotation after insertion, ensuring stability during use. After the lower half of the main housing 11 is mated with the receiving groove 24, the outer edge of the main housing 11 still needs to be outside the receiving groove 24 so that the electrode housing 21 can be removed by holding the outer edge of the main housing 11 during disassembly. The receiving groove 24 and the electrode housing 21 are integrally formed structures with no seams at the contact points with the body, which can avoid scratches or pinching. In addition, because the inner contour of the receiving groove 24 matches the outer contour of the lower half of the main body shell 11, the lateral dimension of the receiving groove 24 is larger than the lateral dimension of the electrode shell 21. The outer side of the bottom plate of the receiving groove 24 can serve as the limiting part for the shell assembly 2 to be inserted into the human body. At the same time, the device can also be removed by holding the edge of the receiving groove 24 after the treatment is completed.

[0023] For the electrode housing 21 with the aforementioned receiving groove 24, the docking mechanism can adopt a snap-fit ​​structure set on the receiving groove 24 and the main housing 11. When the lower half of the main housing 11 mates with the receiving groove 24, the snap-fit ​​structure of the two engages and fixes each other. Alternatively, a magnetic attraction structure can be used, such as... Figure 6 , Figure 7As shown, the docking mechanism includes a first magnetic member 25 disposed within the receiving groove 24 and a second magnetic member 14 disposed within the main housing 11. The lower half of the main housing 11 and the receiving groove 24 are docked and fixed by the attraction force of the first magnetic member 25 and the second magnetic member 14. Preferably, at least two of each of the first magnetic member 25 and the second magnetic member 14 are provided, located at both ends of the main housing 11 and the receiving groove 24, respectively, which can serve both a positioning function and ensure the reliability of the connection. The magnetic structure is easy to assemble and disassemble, the connection is stable and reliable, and it is not prone to wear. Combined with the structure of the receiving groove 24 covering the main housing 11, it can prevent the main unit component 1 from falling off the outer housing component 2 during use and removal of the device.

[0024] like Figure 1 As shown, to ensure the stability of the mating and docking of the lower half of the main casing 11 with the receiving groove 24, multiple silicone plugs 15 are provided around the bottom periphery of the main casing 11. When the lower half of the main casing 11 is mated and docked with the receiving groove 24, the silicone plugs 15 abut against the inner wall of the receiving groove 24. The silicone plugs 15 protrude only slightly from the bottom surface of the main casing 11, which can play a certain buffering role when the first magnetic member 25 and the second magnetic member 14 are attracted, reducing the impact wear between the main casing 11 and the receiving groove 24. They can also play a sealing role after the attraction is stable, preventing the main casing 11 and the receiving groove 24 from shaking.

[0025] like Figure 4 , Figure 7As shown, to facilitate the installation of the circuit module, a top cover 16 is provided on the top of the main unit housing 11. A button 17 is provided on the top cover 16. The top cover 16 can be installed on the main unit housing 11 by means of snap-fit ​​or screw connection. The main unit housing 11 and the guide post 12 can be connected together by snap-fit, threaded connection, or integral injection molding. The circuit module includes a first PCB board 3, a second PCB board 4, a third PCB board 5, a fourth PCB board 6, and a battery 7. The first PCB board 3 and the battery 7 are located inside the main unit housing 11. The fourth PCB board 6 is located at the bottom of the guide post 12. The second PCB board 4 and the third PCB board 5 are located inside the guide post 12, and their upper and lower ends are connected to the first PCB board 3 and the fourth PCB board 6, respectively. The first spring pin 13 is fixed to the fourth PCB board 6. This utility model breaks down the single large circuit board in the traditional therapeutic instrument main unit into multiple small circuit boards, allowing full utilization of the main unit housing space, resulting in a more compact overall structure and facilitating the miniaturization of the device. During installation, the first PCB board 3, the second PCB board 4, the third PCB board 5, and the fourth PCB board 6 are first connected and fixed together by welding or screws, and then the whole assembly is placed into the guide post 12. The first PCB board 3 is installed in the main unit housing 11 with screws to achieve the installation and fixation of the entire circuit board. The entire circuit board layout structure can also provide stable support for the first spring ejector pin 13, ensuring the stability of the first spring ejector pin 13 and the electrode plate 22.

[0026] To charge battery 7, a charging port can be provided on the main casing 11. Considering the overall integrity and aesthetics of the casing structure, wireless charging is preferable, such as... Figure 6 As shown, a charging coil 26 is provided in the receiving groove 24 of the outer casing assembly 2, directly opposite the battery 7. A second spring pin 18 connected to the battery 7 is provided at the bottom of the main casing 11. When the lower half of the main casing 11 mates with the receiving groove 24, the second spring pin 18 contacts the terminal of the charging coil 26. The entire device is typically stored with the main casing assembly 1 and outer casing assembly 2 assembled. Therefore, placing the charging coil 26 in the receiving groove 24 of the outer casing assembly 2 allows the charging coil 26 to be closer to the casing surface, thus ensuring the stability of wireless charging. Furthermore, the first spring pin 13 and the second spring pin 18 may oxidize or rust due to long-term exposure. Therefore, a silicone sleeve 8 can be fitted onto both the first spring pin 13 and the second spring pin 18. The silicone sleeve 8 is fixed to the bottom of the guide post 12 and the bottom of the main casing 11, providing protection and guidance for the first spring pin 13 and the second spring pin 18. When the main unit 1 is separated from the outer casing 2, the ends of the first spring pin 13 and the second spring pin 18 are both located inside the silicone sleeve 8; when the main unit 1 is inserted and fixed to the outer casing 2, the silicone sleeve 8 is compressed, and the ends of the first spring pin 13 and the second spring pin 18 are exposed and come into contact with the electrode plate 22 and the power terminal of the charging coil 26, respectively.
