Description

Technical Field

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

[0002] The pelvic floor muscles are a group of muscles that close the bottom of the pelvis, located between the pubis and coccyx, and play a role in supporting pelvic organs (such as the bladder, uterus, and rectum). Pelvic floor muscle dysfunction is more common in postpartum women and the elderly, and mainly manifests as urinary dysfunction, pelvic organ prolapse, bowel abnormalities, sexual dysfunction, and chronic pelvic pain, which seriously affect quality of life.

[0003] Kegel exercises, as a non-surgical and non-invasive rehabilitation method, have been widely used for the recovery and prevention of pelvic floor muscle function. However, existing training devices have many shortcomings, limiting their effectiveness and user experience in practical applications. For example, existing Kegel balls lack communication interaction with terminals, making it difficult for users to intuitively understand their training progress. Even if a Kegel ball does have communication interaction with a terminal, the signal transmission and reception modules are generally built-in, and the Kegel ball needs to be placed inside the user's vagina, leading to problems such as unstable signal transmission and reception or data transmission and untimely data updates during the communication interaction process.

[0024] One or more technical solutions provided in the embodiments of this utility model have at least the following technical effects or advantages:

[0025] 1. By acquiring the pressure values ​​of the user's pelvic floor muscles through one or more pressure sensors, the system can comprehensively detect the activation status of the pelvic floor muscles. Furthermore, by transmitting the pressure data externally via a transceiver antenna, the system effectively ensures the speed and stability of data transmission, allowing users to understand their training progress in a timely manner.

[0026] 2. By placing the pressure sensor inside the groove, the flexible covering can prevent long-term and significant compression of the pressure sensor when it is not in use, reducing the probability of pressure sensor failure or damage, thereby effectively extending the service life of the pressure sensor.

[0027] 3. Since the training body is equipped with a control module and a vibration motor, corresponding control commands can be sent to the training body using mobile phones, tablets, and other terminals. The communication component transmits the control commands to the control module, which then controls the vibration motor to generate corresponding vibrations to interact with the user during training, thereby reminding the user to change the training rhythm to improve the training effect.

[0028] 4. The training device can also use a vibration motor to massage the user's pelvic floor muscles, relieving training fatigue. Furthermore, by controlling the vibration of the motor, the user's pelvic floor muscles can be stimulated, causing them to passively contract and achieving a passive training effect.

[0029] 5. Since the flexible thin-film pressure sensor includes two electrode layers, an insulating layer and a dielectric layer, the flexible thin-film pressure sensor in this embodiment is a capacitive pressure sensor. Furthermore, the dielectric layer is minimally affected by temperature changes, resulting in a stable baseline, low repeatability error, and short time delay for the flexible thin-film pressure sensor.

Detailed Implementation

[0041] This utility model provides a pelvic floor muscle training device that uses one or more pressure sensors to acquire the pressure value of the user's pelvic floor muscles and transmits the pressure data to the outside via a transceiver antenna. This solves the technical problems in related technologies such as incomplete acquisition of pelvic floor muscle exertion, untimely data transmission, and low transmission stability.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] This utility model provides a pelvic floor muscle training device through one embodiment, such as... Figure 1 As shown, the device includes a training body 100, a power module 200, and one or more pressure sensors 300. When a user intends to train their pelvic floor muscles, the training body 100 needs to be placed inside the user's vagina so that it contacts the pelvic floor muscles, allowing the pressure sensors 300 to detect the exertion of the user's pelvic floor muscles.

[0044] The user's pelvic floor muscle engagement can include: the magnitude and changes in pelvic floor muscle contraction force, the duration of pelvic floor muscle contraction, and the intervals between pelvic floor muscle contractions. Therefore, the engagement of the pelvic floor muscles can reflect the training status of the pelvic floor muscles to a certain extent. Roughly speaking, if the pelvic floor muscle engagement changes from poor at the beginning to good at the end of the pelvic floor muscle training cycle, it can reflect that the pelvic floor muscle training has achieved good results.

[0045] The training unit 100 includes a first protective shell 101 and a signal processing module 102 disposed within the first protective shell 101. One or more pressure sensors 300 are electrically connected to the signal processing module 102 and are located on the outer surface of the first protective shell 101. The pressure sensors 300 can acquire pressure values ​​during the contraction of the user's pelvic floor muscles. A power supply module 200 supplies power to the signal processing module 102 and the one or more pressure sensors 300. The signal processing module 102 is electrically connected to a transceiver antenna 103, and in use, the signal transceiver end of the transceiver antenna 103 can extend outside the user's body in a direction away from the first protective shell 101.

[0046] Specifically, the outer surface of the first protective shell 101 has a through hole (not shown) so that one or more pressure sensors 300 can be electrically connected to the signal processing module 102 through the through hole. The transceiver antenna 103 extends out from the cross-sectional projection area of ​​the first protective shell 101, that is, the extension of the transceiver antenna 103 does not affect the contact between the first protective shell 101 and the pelvic floor muscles.

[0047] In some embodiments, the transceiver antenna 103 extends through the rotation axis of the first protective housing 101. When the user places the training subject 100 inside the body for training, the length of the transceiver antenna 103 should ensure that the signal transceiver end of the transceiver antenna 103 is always outside the user's body, so as to reduce communication obstruction between the signal transceiver end and the terminal device, thereby improving the stability and speed of signal transmission.

[0048] It should be noted that, since the transceiver antenna 103 needs to be exposed outside the first protective shell 101 to receive corresponding wireless signals, and the transceiver antenna 103 needs to penetrate inside the first protective shell 101 to establish an electrical connection with the signal processing module 102, in order to prevent the transceiver antenna 103 from losing its electrical connection with the signal processing module 102 when pulled, it is necessary to reinforce the electrical connection between the transceiver antenna 103 and the signal processing module 102. To this end, the transceiver antenna 103 can be fixed at the perforation in the first protective shell 101, and the length of the transceiver antenna 103 inside the first protective shell 101 should be greater than or equal to the distance between the perforation and the signal processing module 102, to ensure that the transceiver antenna 103 inside the first protective shell 101 has a certain length redundancy, further preventing the transceiver antenna 103 from being torn off.

[0049] Hot melt adhesive, strong glue, or other adhesives can be used to fix the transceiver antenna 103 at the perforation. Alternatively, screw holes can be provided at the perforation, and the transceiver antenna 103 can be pressed and fixed at the perforation by screws and a cover plate.

[0050] To ensure that the pressure sensor 300 makes sufficient contact with the user's pelvic floor muscles, the pressure sensor 300 may include a flexible thin-film pressure sensor, such as... Figure 2 As shown, the flexible thin-film pressure sensor 300 may include a first electrode layer 301, an insulating layer 302, a dielectric layer 303, and a second electrode layer 304 stacked together.

[0051] The dielectric layer 303 can be a porous structure layer with elastic deformation; both the first electrode layer 301 and the second electrode layer 304 can be conductive cloth; conductive filler is also dispersed in the dielectric layer 303; an insulating layer 302 is disposed between the first electrode layer 301 and / or the second electrode layer 304 and the dielectric layer 303, and the insulating layer 302 can prevent the sensor from being broken down. For example, a flexible thin-film pressure sensor is composed of a first electrode layer 301, an insulating layer 302, a dielectric layer 303 and a second electrode layer 304 stacked sequentially from top to bottom.

[0052] For the purpose of fixing and positioning the pressure sensor 300, such as Figure 3 As shown, one or more grooves 104 can be provided around the outer wall of the first protective shell 101, and each groove 104 accommodates a pressure sensor 300. Specifically, the groove 104 is an annular groove, and the pressure sensor 300 is adapted and placed in the annular groove.

[0053] During training, temporary rest or adjustments to the training rhythm can weaken or even eliminate the contractile force of the pelvic floor muscles. To prevent insufficient restraint of the pelvic floor muscles on the training body 100, which could cause it to slip out of the vagina, and to better fit the pelvic floor muscle group for more comprehensive pressure testing, the first protective shell 101 can be designed as a near-cylindrical shape. The cross-sectional diameter of the first protective shell 101 decreases as it approaches the signal transceiver end of the transceiver antenna 103. Therefore, a smaller cross-sectional diameter closer to the vaginal opening better conforms to the structure of the vaginal wall. Furthermore, the top-larger, bottom-smaller structure of the training body 100 makes it easier to secure within the vagina, preventing it from slipping out.

[0054] Because the vaginal environment is a moist and acidic environment, in order to prevent acidic liquids from corroding the training body 100 and the pressure sensor 300, and to extend the overall lifespan of the pelvic floor muscle training device, such as... Figure 3As shown, the device may further include a flexible cover 400. The flexible cover 400 seals and covers the first protective shell 101, the pressure sensor 300, and the transceiver antenna 103. The flexible cover 400 not only keeps the pressure sensor 300 and the transceiver antenna 103 away from the humid and acidic environment, extending their service life, but also, because the flexible cover 400 is made of a flexible material, it can transmit the contraction pressure of the pelvic floor muscles to the pressure sensor 300 encased within it.

[0055] In addition, the transceiver antenna 103 located outside the first protective shell 101 can be covered by a flexible cover 400. The flexible cover 400 forms a protrusion that protrudes from the training body 100. The user can easily pull the training body 100 out of the vagina by pulling the protrusion, preventing the training body 100 from getting stuck in the vagina and being difficult to remove.

[0056] Since the flexible covering 400 encloses the pressure sensor 300, assuming the combined thickness of the pressure sensor 300 and the flexible covering 400 remains constant, a thicker pressure sensor 300 corresponds to a thinner covering 400. If the covering 400 is too thin, it is prone to cracking at that point. Conversely, a thinner pressure sensor 300 corresponds to a thicker covering 400. If the covering 400 is too thick, it may be difficult for the flexible covering 400 to apply pressure to the pressure sensor 300, affecting the pressure detection capability of the pressure sensor 300.

[0057] Therefore, in order to prevent the flexible covering 400 from cracking and to ensure the service life of the flexible covering 400 itself, and also to avoid affecting the pressure transmission path of the flexible covering 400 to the pressure sensor 300, the difference between the thickness of the pressure sensor 300 and the depth of the groove 104 can be controlled within the range of -1mm to 1mm.

[0058] Furthermore, when the thickness of the pressure sensor 300 is less than or equal to the depth of the groove 104, even if the flexible covering 400 is squeezed and moves back and forth in the vagina, the flexible covering 400 will only exert a positive pressure perpendicular to its sensing surface on the pressure sensor 300, and will not exert a shear force parallel to the sensing surface on the pressure sensor 300. This avoids the error between the pressure value obtained by the pressure sensor 300 and the actual pressure value, and also effectively protects the service life of the pressure sensor 300. Therefore, the difference between the thickness of the pressure sensor 300 and the depth of the groove 104 can be controlled within the range of -1mm to 0mm.

[0059] Users inevitably experience boredom and tedium during prolonged self-training. To enhance user motivation, interactive feedback between the training subject (100) and the user can be added. As one possible implementation method, see [example missing]. Figure 3 and 6 As shown, the training body 100 also includes a main circuit board 105, a vibration motor 106, and a control module 107 disposed within the first protective shell 101.

[0060] The vibration motor 106, control module 107, and signal processing module 102 are all electrically connected to the main circuit board 105, enabling the vibration motor 106 to vibrate under the control of the control module 107, providing vibration feedback to the user and thus offering training reminders. For example, it may remind the user that training has ended or that training has begun.

[0061] Users can also train under the guidance of the training unit 100. Specifically, the vibration intensity and / or duration of the vibration motor 106 can be controlled to guide the user to follow the training. The user follows the vibration to control the contraction strength and / or duration of the pelvic floor muscle group. The contraction strength can be positively correlated with the vibration intensity, and the vibration duration can be equal to the contraction duration.

[0062] For example, in the first training phase, the vibration intensity of the vibration motor 106 is controlled within a first intensity threshold, and the vibration duration is a first duration. The user can follow the vibration to contract the pelvic floor muscles for the first duration, and control the contraction force of the pelvic floor muscles to ensure that the pressure value detected by the pressure sensor 300 is not lower than the first pressure threshold. In the second training phase, the vibration intensity of the vibration motor 106 is increased or decreased to a second intensity threshold, and the vibration duration is a second duration. The user can follow the vibration to contract the pelvic floor muscles for the second duration, and control the contraction force of the pelvic floor muscles to ensure that the pressure value detected by the pressure sensor 300 is not lower than the second pressure threshold.

[0063] In addition, the vibration intensity and / or duration of the vibration motor 106 can be controlled to provide vibration massage to the user's pelvic floor muscles, thereby relieving pelvic floor muscle fatigue. Furthermore, by controlling the vibration of the vibration motor, the user's pelvic floor muscles can be stimulated, causing passive contraction movements and achieving a passive training effect on the user's pelvic floor muscles.

[0064] Furthermore, the signal processing module 102 can receive and process vibration commands sent by terminals such as mobile phones and tablets through the transceiver antenna 103, and through the electrical connection between the signal processing module 102, the main circuit board 105, and the control module 107, the control module 107 receives and sends vibration signals to the vibration motor 106 based on the vibration commands, and the vibration motor 106 responds to the vibration signals to perform the corresponding vibration.

[0065] In specific implementation, the vibration motor 106 can be any one of a rotor motor, an X-axis motor, a Y-axis motor, or a Z-axis motor.

[0066] Because the entire training device (100) is enclosed within the user's body during pelvic floor muscle training, the user can only perform actions such as powering off and changing training modes, intensity, and duration via a mobile phone, tablet, or other device. Figure 4 As shown, the pelvic floor muscle training device provided by this utility model may also include a training sub-body 500, which is always located outside the user's body and can provide the user with some peripheral control functions, such as power on / off, switching of working modes, and firmware upgrades.

[0067] Specifically, see reference as follows Figure 5 , 7 As shown in Figure 8, the training sub-body 500 may include a second protective shell 501, a sub-circuit board 502, and a button 503 and an external interface 504 electrically connected to the sub-circuit board 502. The sub-circuit board 502 is disposed inside the second protective shell 501, and the second protective shell 501 exposes the external interface 504 and the button 503. The sub-circuit board 502 can be electrically connected to the main circuit board 105 via wires (not shown).

[0068] Button 503 may include one or more of a power switch, a mode button, and a reset button. The power switch powers the device on / off, the mode button switches training modes, and the reset button is used to reset and restore the device in case of a program bug. Additionally, automatic initialization upon startup can be programmed to avoid some program runtime bugs, or a reset command can be sent directly to the signal processing module 102 via a terminal device to reset and restore the device. External interface 504 may include a charging interface and / or a data transmission interface. The charging interface provides power to the power module 200, and the data transmission interface is used for program writing, program debugging, and reading training data.

[0069] To ensure the normal operation of the vibration motor 106, the power module 200 also supplies power to the main circuit board 105, the sub-circuit board 502, the vibration motor 106, and the control module 107. In specific implementations, the power module 200 can be a rechargeable battery and / or a power converter. A rechargeable battery enables wireless power supply, freeing users from cable constraints. Compared to a rechargeable battery, a power converter provides a long-term, stable power supply to the device, preventing functional degradation such as vibration intensity and signal strength when the battery is low.

[0070] In order to make full use of the internal space of the training body 100 and reduce the overall volume of the pelvic floor muscle training device, the power module 200 can be set inside the training body 100. In some embodiments, the power module 200 can also be set only inside the training sub-body 500 to avoid the potential harm to the user caused by the risk of battery explosion or combustion in extreme cases.

[0071] Also for the purpose of protecting the training sub-body 500, the entire training sub-body 500 can be covered with a sealing layer 505, which exposes the external interface 504 and encloses the button 503.

[0072] Furthermore, the training main body 100 and the training auxiliary body 500 can be integrated into one unit. In this regard, the end of the flexible cover 400 away from the training main body 100 can be connected to the training auxiliary body 500, wherein the sealing layer 505 is provided with an opening or base for installing the flexible cover 400.

[0073] Alternatively, the flexible covering 400 between the training main body 100 and the training sub-body 500 can be set as a hollow structure, which can wrap the transceiver antenna 103 and the wires inside, which can not only extend the service life of the transceiver antenna 103 and the wires, but also improve the overall aesthetics of the device.

[0074] In particular, as an optional implementation, the transceiver end of the transceiver antenna 103 is positioned between the training main body 100 and the training sub-body 500, meaning that the transceiver end of the transceiver antenna 103 is neither located within the training main body 100 nor within the training sub-body 500. This not only reduces communication obstruction between the transceiver antenna 103 and the terminal device but also allows the transceiver antenna 103 to slide freely within the flexible covering 400. Even if the flexible covering 400 is pulled, it will not pull on the transceiver antenna 103, avoiding the transceiver antenna 103 from bearing tensile forces and effectively extending the working life of the transceiver antenna 103.

[0075] See also Figure 7 As shown, a boss 401 is provided on the end of the flexible cover 400 that connects to the training sub-body 500. The connection between the flexible cover 400 and the training sub-body 500 is achieved by engaging the boss 401 with the opening or the base.

[0076] If the sealing layer 505 is designed as a base, since the base will not penetrate the sealing layer 505, the flexible covering 400 can be connected to the sealing layer 505 via the base, further enhancing the waterproof performance of the training sub-body 500. Furthermore, the connection between the flexible covering 400 and the second protective shell 501 within the sealing layer 505 makes the connection between the training main body 100 and the training sub-body 500 more stable. Specifically, by snapping the boss 401 into the sealing layer 505, the sealing layer 505 covers the flexible covering 400 at the connection point, effectively reducing gaps at the joint and improving waterproof performance.

[0077] To further enhance the connection stability between the flexible covering 400 and the training sub-body 500, this can be achieved through any one or all of the following implementation methods:

[0078] Method 1: The diameter of the boss 401 is smaller the closer it is to the training body 100, and the diameter of the boss 401 is larger than the opening or the boss 401 is adapted to the base.

[0079] When the training sub-body 500 is pulled, the end connecting the flexible cover 400 and the training sub-body 500 is subjected to a pulling force away from the training body 100. Along the direction of this pulling force, the diameter of the protrusion 401 of the training body 100 increases, and at least a portion of the diameter of the protrusion 401 is larger than the opening. Since the protrusion 401 is part of the flexible cover 400, the flexible protrusion 401 can engage with the opening on the sealing layer 505. When the protrusion 401 engages with the opening, pulling the training sub-body 500 will make the engagement between the opening and the protrusion 401 increasingly tighter, thereby enhancing the connection between the flexible cover 400 and the training sub-body 500.

[0080] Method 2: A snap-fit ​​groove is provided on the boss 401, and a snap-fit ​​block matching the snap-fit ​​groove is provided on the opening or the base.

[0081] The connection between the flexible covering body 400 and the training sub-body 500 is strengthened by the interlocking of the interlocking groove and the interlocking block. The number of interlocking blocks can be set according to the connection strength. Under the same conditions, the more interlocking blocks, the higher the connection strength. One interlocking block fits one interlocking groove. The number of interlocking blocks is not detailed here. The shape of the interlocking block can be any one or more of the following: rectangular block, hook-shaped block, cylinder, semi-cylinder, and triangular block. The shape of the interlocking groove matches the shape of the interlocking block.

[0082] Method 3: A snap-fit ​​block is set on the boss 401, and a snap-fit ​​groove matching the snap-fit ​​block is set on the opening or the base.

[0083] Similar to method two, method three simply swaps the positions of the snap-fit ​​blocks and the snap-fit ​​grooves. The number and shape of the snap-fit ​​blocks can be referenced from method two.

[0084] As an alternative implementation, the external interface 504 needs to be exposed outside the sealing layer 505 in order to establish a physical connection with external devices. When the external interface 504 is not in use, it needs to be physically protected to avoid short circuits, contact corrosion, and other issues.

[0085] In this regard, the device may also include a sealing plug 506.
