Description

Technical Field

[0001] This utility model relates to the field of pelvic floor muscle repair technology, and in particular to a pelvic floor muscle repair device. Background Technology

[0002] Electrical muscle stimulation (EMS) has been proven to be an effective tool for modulating and retraining muscles. Its core effectiveness lies in its ability to target and stimulate the target muscle at the appropriate frequency.

[0003] However, when EMS is applied to pelvic floor muscle treatment in women, individual differences (such as weight, number of childbirths, etc.) affect the anterior and posterior position of the pelvic floor muscles, meaning the length of the pelvic floor muscles varies from person to person. In existing pelvic floor muscle repair devices, the electrode positions are fixed, making it difficult to achieve targeted stimulation for most patients, resulting in poor repair effects. Furthermore, during patient movement, relative displacement may occur between the electrodes and the pelvic floor muscles, causing misalignment and also affecting the repair outcome.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] refer to Figures 1-7 As shown in the figure, an embodiment of this utility model proposes a pelvic floor muscle repair device, including a main unit 10, a flexible substrate 1, an electrode assembly, and a conductive adhesive component. The flexible substrate 1 includes contact surfaces and non-contact surfaces spaced apart along its thickness direction. The non-contact surfaces can contact the user's undergarments to limit the flexible substrate 1 through the undergarments. The elastic deformability of the flexible substrate 1 allows the electrode assembly to deform according to the user's body contour or the shape of the undergarments during use, making it convenient and more form-fitting. The electrode assembly is disposed on the contact surface of the flexible substrate 1 and electrically connected to the main unit 10 through a conductor 20 such as a lead wire or conductive silicone. The electrode assembly includes at least two electrodes spaced apart along the front-back direction of the flexible substrate 1. For ease of description, the electrode disposed in front is defined as the second electrode 3, and the electrode disposed in back is defined as the first electrode 2. Both the first electrode 2 and the second electrode 3 are electrically connected to the main unit 10. When both the first electrode 2 and the second electrode 3 are in contact with the user's body surface, a conductive circuit is formed between the electrode assembly, the main unit 10, and the user, thereby generating bioelectric stimulation at a specific frequency to repair the pelvic floor muscles through electrical stimulation. The distance between the first electrode 2 and the second electrode 3 is adjustable. It can be understood that when the flexible substrate 1 is positioned approximately at the corresponding pelvic floor muscles by the user's close-fitting clothing, the area corresponding to the front of the body is called the front, and the area corresponding to the back of the body is called the back. That is, the second electrode 3 is located on the front of the body, and the first electrode 2 is located on the back of the body. The second electrode 3 is used to act on the pelvic floor muscles near the pubic bone, and the first electrode 2 is used to act on the anal sphincter.

[0032] The distance between the second electrode 3 and the first electrode 2 in the electrode assembly of the above-mentioned pelvic floor muscle repair device is adjustable in the front-back direction. Therefore, when facing different body types of different users, the distance between the first electrode 2 and the second electrode 3 can be adjusted according to the length of the user's pelvic floor muscles, thereby adjusting the range of microcurrent action, achieving targeted stimulation, and improving the repair effect.

[0033] The flexible substrate 1 can be made of medical-grade silicone, plastic, or other flexible materials that are waterproof and insulating. (See reference...) Figure 1As shown, its overall structure is a long, thin pad-like strip, narrow in the middle and wide at both ends. The flexible substrate 1 can be connected to the user's underwear in a detachable manner, such as by adhesive or tie-on, or it can be placed only on the inside of the underwear without being fixedly connected to it, but rather limited by the user.

[0034] In one embodiment, the first electrode 2 and the second electrode 3 are both rotatably disposed on the flexible substrate 1, and conductive adhesives are provided on the surfaces of the first electrode 2 and the second electrode 3 to adhere the first electrode 2 and the second electrode 3 to human skin.

[0035] The electrode assembly is adhered to the user's skin via conductive adhesive, fixing its relative position to the pelvic floor muscles. This prevents misalignment of the electrode assembly and pelvic floor muscles caused by displacement of the flexible substrate 1 during various usage scenarios such as walking, sitting, and lying down, further improving the repair effect. Furthermore, both the first electrode 2 and the second electrode 3 are rotatably connected to the flexible substrate 1, reducing the pulling between the flexible substrate 1 and the first electrode 2 or second electrode 3 when the substrate shifts in various usage scenarios. This avoids a pulling sensation at the point where the conductive adhesive is attached to the skin, improving the user experience.

[0036] refer to Figure 2 and Figure 3 As shown, the flexible substrate 1 is wrapped around the main unit 10 by a potting method, and the conductor 20 connecting the main unit 10 and the electrode assembly is also wrapped in it. Compared with the main unit 10 and the flexible substrate 1 being set separately and connected by the conductor 20, the foreign body feeling caused by the conductor 20 can be reduced, and the user experience can be further improved.

[0037] Furthermore, to ensure a better fit between the first electrode 2 and the second electrode 3 and the user's skin, both electrodes 2 and 3 are sheet-like and made of flexible conductive materials. For example, the first electrode 2 and the second electrode 3 can be made of non-metallic materials such as conductive PU or nylon conductive fabric. In the current embodiment, the conductive adhesive is detachably connected to both the first electrode 2 and the second electrode 3. For example, the conductive adhesive can be a gel sheet, which is adhered to the surfaces of the first electrode 2 and the second electrode 3. The gel sheet is disposable, saving costs and ensuring hygiene.

[0038] refer to Figure 1 and Figure 2 As shown, in this embodiment, the first electrode 2 and the second electrode 3 are both set to be approximately U-shaped, and the U-shaped openings of the first electrode 2 and the second electrode 3 are set opposite to each other to avoid the user's perineum. The skin of the perineum has many folds, so its ability to receive current stimulation is low. The U-shaped first electrode 2 and the second electrode 3 can avoid the perineum without reducing the therapeutic effect on the pelvic floor muscles, thereby improving the user's experience.

[0039] It is understandable that, in order to achieve adjustable spacing between the first electrode 2 and the second electrode 3, the position of at least one of the first electrode 2 and the second electrode 3 on the flexible substrate 1 must be adjustable. The following description will use the adjustable position of the first electrode 2 on the flexible substrate 1 as an example to specifically describe the connection method between the first electrode 2, the second electrode 3 and the flexible substrate 1.

[0040] refer to Figures 2-5 As shown, in one embodiment, the first electrode 2 is connected to the flexible substrate 1 via a magnetic connection. Specifically, one of the first electrode 2 and the flexible substrate 1 is provided with a first magnetic female buckle 5, and the other is provided with a first magnetic male buckle 4. The first magnetic female buckle 5 is provided with a groove extending along the length direction of the flexible substrate 1, and the first magnetic male buckle 4 is provided with a magnetic protrusion. The magnetic protrusion is embedded in the groove to achieve a magnetic connection between the first electrode 2 and the flexible substrate 1, and the magnetic protrusion can slide within the groove to achieve stepless adjustment of the distance between the first electrode 2 and the second electrode 3. The first magnetic female buckle 5 or the first magnetic male buckle 4 provided on the flexible substrate 1 is electrically connected to the host 10, thereby achieving an electrical connection between the first electrode 2 and the host 10 when the first magnetic male buckle 4 and the first magnetic female buckle 5 are magnetically connected.

[0041] The first magnetic male buckle 4 can rotate relative to the first electrode 2 or the flexible substrate 1 on which it is located, and / or the first magnetic male buckle 4 can rotate relative to the first magnetic female buckle 5, thereby realizing the rotation of the first electrode 2 relative to the flexible substrate 1. Based on the premise that the first magnetic male buckle 4 can rotate relative to the first magnetic female buckle 5, the cross-section of the magnetic protrusion on the first magnetic male buckle 4 is set to be circular.

[0042] The second electrode 3 can also be connected to the flexible substrate 1 via magnetic attraction. Furthermore, the second electrode 3 can be connected to the flexible substrate 1 in the same way as the first electrode 2, or it can be rotatably connected only to the flexible substrate 1. Based on the premise that the second electrode 3 and the flexible substrate 1 only rotate relative to each other, in one embodiment, a second magnetic female buckle 7 is provided on one of the second electrode 3 and the flexible substrate 1, and a second magnetic male buckle 6 is provided on the other. The second magnetic female buckle 7 or the second magnetic male buckle 6 on the flexible substrate 1 is electrically connected to the host 10. The second magnetic female buckle 7 has a fastening groove, and the second magnetic male buckle 6 has a fastening protrusion. The fastening protrusion can be embedded in the fastening groove and rotate within the fastening groove, thereby achieving a rotatable connection between the second electrode 3 and the flexible substrate 1. Of course, the second magnetic male buckle 6 can also be configured to rotate relative to the second electrode 3 or the flexible substrate 1 it is located on, which also achieves the rotation of the second electrode 3 relative to the flexible substrate 1.

[0043] refer to Figure 6As shown, in another embodiment, the first electrode 2 is connected to the flexible substrate 1 via a snap-fit ​​connection. Specifically, one of the first electrode 2 and the flexible substrate 1 is provided with a snap-fit ​​8, and the other is provided with a snap-fit ​​member 9 with snap holes 91. Multiple snap holes 91 and snap-fit ​​8 are spaced apart along the length of the flexible substrate 1. The first electrode 2 and the flexible substrate 1 are snapped together by the snap-fitting snap-fit ​​8 and snap holes 91. By switching the engaging snap-fit ​​8 and snap holes 91, the position of the first electrode 2 relative to the flexible substrate 1 can be adjusted.

[0044] To enable rotation of the first electrode 2 relative to the flexible substrate 1, the latch 8 can rotate within the latch hole 91 and / or the latch 8 is rotatably mounted on the first electrode 2 or the flexible substrate 1. (Reference) Figure 7 As shown, in one embodiment, the latch 8 includes a limiting part 82 and a connecting part 81. The connecting part 81 is connected to the first electrode 2 and is cylindrical. The limiting part 82 is located at the end of the connecting part 81 away from the first electrode 2, and the orthographic projection of the limiting part 82 toward the latch hole 91 is larger than the cross-sectional area of ​​the latch hole 91. More specifically, the latch 8 is disposed on the first electrode 2, and the latching member 9 is disposed on the flexible substrate 1 and electrically connected to the host 10 to reduce the foreign body sensation caused by the latch 8. At the same time, in order to reduce the difficulty of removing the first electrode 2 from the flexible substrate 1 and to replace the first electrode 2 in a timely manner, the limiting part 82 is spherical.

[0045] The second electrode 3 can also be snapped to the flexible substrate 1, which will not be described in detail here. It is worth emphasizing that the first electrode 2 and the second electrode 3 can also be connected by magnetic attraction and snap-fit, respectively, or the first electrode 2 and the second electrode 3 can be connected by snap-fit ​​and magnetic attraction, respectively.

[0046] In the above embodiments, both the first electrode 2 and the second electrode 3 are detachably connected to the flexible substrate 1. Compared with non-detachable connections, the first electrode 2 and the second electrode 3 can be replaced periodically, extending the service life of the pelvic floor muscle repair device.

[0047] refer to Figure 2 and Figure 3As shown, the main unit 10 is positioned on the side of the second electrode 3 away from the first electrode 2, which reduces the foreign body sensation caused by the main unit 10 when using the pelvic floor muscle repair device, especially when the user is sitting or lying down. Specifically, the main unit 10 includes a main unit shell 101, a PCB board 102, a battery 103, and an operating component 104. The main unit shell 101 is used to enclose the PCB board 102 and the battery 103 into a single unit. It is made of flexible materials that are waterproof and insulating, including but not limited to flexible silicone and flexible plastic. The PCB board 102 is used to control the overall operation of the pelvic floor muscle repair device and is electrically connected to the battery 103 and the second electrode 3. The battery 103 provides energy to the electrode assembly and the PCB board 102. The operating component 104 is used to turn the main unit 10 on and off and adjust the frequency and / or voltage of the generated microcurrent. One end of the conductor 20 is connected to the PCB board 102, and the other end is connected to the first electrode 2 away from the PCB board 102.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
