[0032] A pelvic floor muscle stimulator is a portable medical device used for rehabilitation therapy. It is widely used in postpartum recovery, urinary incontinence prevention, and pelvic floor muscle function training.
[0033] In existing technologies, these devices are primarily powered by disposable batteries or wired charging. While disposable batteries offer convenience through replacement, they also present several drawbacks in practical use. For instance, limited battery capacity and short usage time necessitate frequent replacements, causing inconvenience to users. Furthermore, improper disposal of discarded batteries can lead to environmental pollution, and the long-term cost is high, hindering the sustainable use of the device. On the other hand, while wired charging is reusable, it typically relies on a micro-USB interface or a dedicated charging port, which is susceptible to moisture, oxidation, or contamination. This is particularly problematic in humid environments, easily affecting charging stability and potentially damaging the device, thus reducing its lifespan and reliability.
[0034] Therefore, there is an urgent need to provide an improved charging structure for pelvic floor muscle stimulators to overcome the problems of high cost and poor environmental performance of disposable batteries in existing technologies, as well as the fragility and instability of wired charging interfaces. This would improve the convenience, safety, and durability of the device and meet the development needs of modern medical rehabilitation equipment for high performance and high reliability.
[0035] Please see Figures 1 to 4 This utility model provides a pelvic floor muscle stimulation device 10, which includes a magnetic charging chamber 100 and a stimulator 200. The stimulator 200 can be placed in the charging cavity 111 and magnetically contacted with the charging module 130.
[0036] In detail, the magnetic charging case 100 includes a housing 110, a control component 120, and a charging module 130.
[0037] The outer casing 110 contains an isolated charging cavity 111 and a mounting cavity 112, resulting in a more rational overall structural layout and clear functional area division. The charging cavity 111 houses the stimulator 200, while the control component 120 is located within the mounting cavity 112. This physically isolates the electrical control system from the charging actuator, improving the overall structural safety and facilitating future maintenance and debugging.
[0038] The charging module 130 includes a housing 131, a magnetic 132, and a charging coil 133. The housing 131 is disposed in the charging cavity 111, and the magnetic 132 is disposed on the surface of the housing 131 for adsorbing the stimulator 200, so that it can be stably placed and accurately connected to the charging coil 133. The charging coil 133 is disposed inside the housing 131 and electrically connected to the control component 120 to ensure that it can output stable power to the stimulator 200.
[0039] Therefore, the magnetic charging case 100 provided in this embodiment of the present invention not only realizes non-contact charging and avoids the failure risk brought about by traditional charging interfaces, but also enhances the positioning accuracy between the stimulator 200 and the charging module 130 through the adsorption effect of the magnetic component 132, thereby improving charging efficiency and user experience.
[0040] Furthermore, there are multiple magnetic attracting elements 132, which are arranged in a matrix on the surface of the housing 131.
[0041] It is worth noting that the surface of the stimulator 200 is provided with an adsorption element 210 corresponding to the magnetic element 132.
[0042] Therefore, by setting multiple magnetic components 132 and multiple adsorption components 210 in a one-to-one correspondence, after the stimulator 200 is placed into the charging chamber 111, no additional rotation or adjustment is required. The multiple magnetic components 132 can automatically adsorb the multiple adsorption components 210 at the bottom of the stimulator 200 in a one-to-one correspondence, thereby achieving fast and stable docking.
[0043] It is evident that setting multiple magnetic components 132 in a matrix arrangement not only improves the adsorption stability and positioning accuracy between the stimulator 200 and the magnetic charging case 100, but also significantly optimizes the user's operating experience.
[0044] Optionally, the number of magnetic elements 132 and adsorption elements 210 can be four.
[0045] Furthermore, the housing 131 is provided with a groove 134, the bottom wall of the groove 134 is an arc-shaped concave surface, and the magnetic attractor 132 is disposed in the groove 134.
[0046] It should be noted that the groove 134 is an accommodating space formed by a partial inward recess on the surface of the housing 131. Its shape corresponds to the bottom shape of the stimulator 200 and is used to define the placement position of the stimulator 200 in the charging chamber 111.
[0047] Specifically, the bottom wall of the groove 134 adopts an arc-shaped concave structure, and its radius of curvature is adapted to the curvature of the corresponding area at the bottom of the stimulator 200. This allows the stimulator 200 to be more stably attracted and fixed to the magnetic attractor 132 in the groove 134, reducing the displacement or sliding caused by external disturbances.
[0048] Furthermore, the charging module 130 also includes a seal (not shown) disposed on the edge of the groove 134, which is used to fit against the stimulator 200.
[0049] In this embodiment, when the stimulator 200 is adsorbed into the groove 134, the sealing element undergoes elastic deformation due to the pressure from the bottom of the stimulator 200, thereby filling any gaps that may exist between them and ensuring a tight seal at the contact surface. Therefore, this not only improves the operational stability of the magnetic charging case 100 in humid environments but also meets the actual need for complete immersion protection during the cleaning and disinfection process of medical devices.
[0050] Alternatively, the seal may be a silicone sealing ring, and may be injection molded from medical-grade liquid silicone.
[0051] Furthermore, a limiting member 113 is also provided inside the housing 110. The limiting member 113 is disposed inside the mounting cavity 112 and is disposed opposite to the charging module 130. The limiting member 113 is provided with a limiting groove.
[0052] In this embodiment, when the stimulator 200 is placed in the charging cavity 111, the stimulator 200 is positioned between the charging module 130 and the limiting member 113. Furthermore, the limiting member 113 can effectively support and limit the stimulator 200 through the limiting groove, preventing unnecessary displacement or shaking within the charging cavity 111, thereby ensuring stable contact between the charging module 130 and the stimulator 200.
[0053] Furthermore, the control component 120 includes a control element 121 and an indicator light 122. The charging coil 133 and the indicator light 122 are both connected to the control element 121, and the indicator light 122 is used to display the charging status.
[0054] In practical applications, once the stimulator 200 is placed in the charging chamber 111 and secured by the magnetic attractant 132, the control element 121 immediately detects the change in magnetic field and the load response of the charging coil 133, and initiates the charging process. At this time, the indicator light 122 switches to the corresponding color according to the command of the control element 121, allowing the user to intuitively understand the current charging status without operating an additional interface.
[0055] For example, indicator light 122 includes a tri-color LED indicator 122, where red indicates that the charging compartment is connected to a power source, blue indicates that it is charging, and green indicates that charging is complete. Indicator light 122 is controlled by control element 121 and can automatically adjust the display status according to the power status of stimulator 200.
[0056] It is understandable that the control element 121 can be, but is not limited to, a PCB board.
[0057] Furthermore, the outer casing 110 includes an upper cover 114, a lower cover 115, and an outer frame 116. The upper cover 114 and the lower cover 115 are disposed opposite to each other. Both the upper cover 114 and the lower cover 115 are provided with an isolation portion 117. The outer frame 116 is disposed around the connection between the upper cover 114 and the lower cover 115. The upper cover 114, the lower cover 115, and the outer frame 116 together form the internal cavity of the outer casing 110. The isolation portion 117 divides the internal cavity into a charging cavity 111 and a mounting cavity 112.
[0058] In this embodiment, by constructing the outer shell 110 as a composite structure consisting of an upper cover 114, a lower cover 115 and an outer frame 116, and by using the isolation part 117 to functionally partition the internal chamber, not only is the overall structural strength and assembly precision of the magnetic charging compartment 100 improved, but it also demonstrates outstanding technical advantages in optimizing electrical isolation performance, enhancing heat dissipation efficiency and ensuring long-term stable operation of the equipment.
[0059] Optionally, the bottom surface of the lower cover 115 or the inner wall of the charging cavity 111 is provided with an anti-slip pad (not shown in the figure). The anti-slip pad is made of silicone and is used to increase the stability of the device.
[0060] It is worth mentioning that the housing 131 is made of thermoplastic composite material through injection molding. The thermoplastic includes ABS (acrylonitrile-butadiene-styrene copolymer) and PC (polycarbonate), which gives the housing 131 excellent impact resistance, heat resistance and good dimensional stability, thereby extending the service life of the magnetic charging case 100.
[0061] It is understood that the upper cover 114, lower cover 115 or outer frame 116 are also provided with a structure that can open or close the charging chamber 111, so as to put the stimulator 200 into the charging chamber 111 or take it out of the charging chamber 111. The structure is not specifically limited here, as long as it can achieve the above functions.
[0062] In summary, this utility model provides a magnetic charging case 100 and a pelvic floor muscle stimulation device 10. The magnetic component 132 enables automatic alignment and magnetic fixation between the stimulator 200 and the charging module 130, eliminating the need for manual adjustment by the user. This simplifies operation and enhances adaptability, making it particularly suitable for users with limited hand dexterity, thus improving device accessibility and user compliance. Furthermore, by eliminating the traditional physical charging interface, the completely enclosed interface-free structure significantly reduces the circuit failure rate caused by humid environments, extending the device's lifespan while improving product safety and durability. Therefore, the magnetic charging case 100 structure provided by this utility model effectively improves charging efficiency, enhances device stability, improves user experience, and meets the waterproof requirements for medical devices.
[0063] In practical applications, when the user places the stimulator 200 into the charging chamber 111, the magnetic attachment 132 on the surface of the housing 131 quickly identifies and attracts the corresponding attachment 210 at the bottom of the stimulator 200, ensuring that the stimulator 200 can only be placed in one correct orientation. At this time, the charging coil 133 located inside the housing 131 begins to supply electrical energy to the stimulator 200 through electromagnetic induction. The entire process requires no plugging or unplugging, reducing operational complexity. In addition, the control component 120 monitors the charging status in real time and provides feedback to the user through the indicator light 122, allowing the user to intuitively understand whether the device is charging or fully charged, thus improving the interactive experience. Therefore, this magnetic charging chamber 100 not only solves many defects in traditional charging methods but also further improves the convenience, safety, and intelligence of medical devices in daily use.
[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
