Abstract
Description
Technical Field
[0001] This invention relates to the field of pelvic floor muscle exercise technology, and more particularly to a pelvic floor muscle exercise device that uses pressure sensing and vibration stimulation. Background Technology
[0002] In existing technologies, the pelvic floor muscles are a group of muscles that support the urethra, vagina, rectum, and other parts of the pelvic floor. They play an important role in various bodily functions such as urination / defecation, sexual function, and organ support. However, due to factors such as pregnancy / childbirth, aging, obesity, prolonged sitting, and abnormal pelvic alignment, these muscles may become weak, leading to increased discomfort related to urinary incontinence or pelvic floor relaxation. Traditionally, self-training exercises such as Kegel exercises are widely recommended, but this self-exercise has limitations. Users often find it difficult to judge whether they are contracting the correct area and with the appropriate intensity, and may mistakenly use abdominal, gluteal, or thigh muscles instead of the target muscles, repeating incorrect movement patterns and reducing the effectiveness of the exercise.
[0003] Chinese Patent Publication No. CN109568897A discloses a pelvic floor muscle function training device and system. The pelvic floor muscle function training device consists of a sensor module, a timer, a counter, a central data processor, an integrated circuit chip, a power supply, and a wireless communication module, encapsulated in silicone and fabricated into a sheet shape. The sensor module includes a temperature sensor, a humidity sensor, a pressure sensor, a displacement sensor, an acceleration sensor, an electromyography sensor, a pH sensor, a heart rate sensor, a blood pressure sensor, and a blood oxygen saturation sensor. The temperature sensor is located on the inner and outer surfaces of the pelvic floor muscle function training device, respectively, to collect body temperature data of male and female users, construct a body temperature database, and, through a specific algorithm, plot the menstrual cycle curve of female users, distinguishing between physiological body temperature increases and body temperature increases in disease states, and also reflecting the blood circulation status of the pelvic floor muscles. The humidity sensor is located on the outer surface of the pelvic floor muscle function training device. The displacement sensor collects the amplitude of tissue or organ movement during Kegel exercises. The acceleration sensor collects the acceleration of tissue or organ movement during Kegel exercises. The pressure sensor is located on the inner and outer surfaces of the device. The pelvic floor muscle function training device has at least two inner and outer surfaces, used to collect pelvic muscle tension values during pelvic floor muscle function training for female users; the electromyography (EMG) sensor module is located on the outer surface of the pelvic floor muscle function training device to collect pelvic floor muscle function data during training; the pH sensor is located on the outer surface of the pelvic floor muscle function training device to collect the pH value of the female user's internal environment and to construct a female user's internal environment health database; the heart rate sensor is located on the inner and outer surfaces of the pelvic floor muscle function training device to collect heart rate data for male and female users; the blood pressure sensor is located on the inner and outer surfaces of the pelvic floor muscle function training device to collect blood pressure data for male and female users; the blood oxygen saturation sensor is located on the inner and outer surfaces of the pelvic floor muscle function training device to collect blood oxygen saturation data for male and female users; the timer is used to record the start and end time and duration of a single pelvic floor muscle function training session; and the counter is used to record the number of repetitions of a single pelvic floor muscle function training session. Therefore, it can be seen that the pelvic floor muscle function training device and system have problems such as difficulty in distinguishing the actual pelvic floor muscle contraction due to the sensitivity difference of the pressure sensor set in different positions, and lack of intuitive feedback to inform the user whether the user has deviated from the target pressure range in a sitting position. Summary of the Invention
[0004] To address this, the present invention provides a pelvic floor muscle exercise device that uses pressure sensing and vibration stimulation to overcome the problems in the prior art where the sensitivity of pressure sensors placed at different locations makes it difficult to distinguish the actual pelvic floor muscle contraction, and lacks intuitive feedback to inform users whether they have deviated from the target pressure range in a seated environment.
[0005] To achieve the above objectives, the present invention provides a pelvic floor muscle exercise device that senses pressure and stimulates vibration, comprising: The main body is used to provide seating positions; An airbag mechanism, which is connected to the main body, is used to form contact pressure by adjusting air pressure. It includes a first airbag part for protruding and contracting vertically by adjusting a first air pressure to form a first contact pressure, a second airbag part that is linearly arranged on the main body with the first airbag part for controlling the protrusion height by adjusting a second air pressure to form a second contact pressure, and a third airbag part that is arranged on the side of the main body away from the first airbag part for forming a third contact pressure. A vibration mechanism, which is connected to the airbag mechanism, is used to output vibration signals; A detection mechanism, connected to the airbag mechanism, is used to detect the first contact pressure, the second contact pressure, and the third contact pressure respectively; A controller, connected to the airbag mechanism, the vibration mechanism, and the detection mechanism, is used to determine the corresponding target pressure range based on the output mode. It is also used to control the contraction intensity of the airbag mechanism, adjust the vibration mode of the vibration mechanism, switch the cyclic operation phase, and adjust the vibration mode of the vibration mechanism under any of the output modes, based on a comparison between the contact pressure and the corresponding target pressure range. The cycle operation phases include a relaxation phase, an exertion phase, and a holding phase; the vibration modes include a relaxation vibration mode, a feedback vibration mode, and a massage vibration mode; and the output modes include anal mode, urethral / vaginal mode, adductor muscle mode, and a combined mode.
[0006] Furthermore, the testing institution includes: A first pressure sensor, which is connected to the first airbag portion, is used to detect the first contact pressure; A second pressure sensor, which is connected to the second airbag portion, is used to detect the second contact pressure; A third pressure sensor, which is connected to the third airbag portion, is used to detect the third contact pressure.
[0007] Furthermore, the airbag mechanism also includes: An air pump is used to supply air to the first airbag section, the second airbag section and the third airbag section respectively; Several solenoid valves are connected to the air pump to adjust the air volume of the first airbag, the second airbag and the third airbag respectively. Several springs are respectively disposed above several of the solenoid valves to provide a restoring force that causes the airbag to contract during exhaust.
[0008] Furthermore, the controller is connected to several pressure sensors to control the amount of air that the air pump inputs to the first airbag, the second airbag, and the third airbag, respectively, so that the first contact pressure, the second contact pressure, and the third contact pressure reach the corresponding target pressure range.
[0009] Furthermore, it also includes an indicator mechanism connected to the controller for outputting visual and voice signals.
[0010] Furthermore, the controller is configured to increase the contraction strength when any of the contact pressures is less than the corresponding target pressure range; Under any of the contact pressures being greater than the corresponding target pressure range, the visual signal, the voice signal, and the vibration signal are output respectively.
[0011] Furthermore, the controller is used to control the airbag mechanism to operate sequentially according to the relaxation phase, the exertion phase, and the holding phase; Under the conditions of each stage transition, the indicating mechanism is controlled to output the visual signal or the voice signal for indication; Under the conditions of the holding phase, the corresponding vibration output mode and the display color and illumination mode of the visual signal are adjusted according to the deviation between the contact pressure and the corresponding target pressure range.
[0012] Furthermore, the controller is connected to the vibration mechanism to output a low-amplitude, low-frequency relaxation vibration mode when any of the contact pressures is within the corresponding target pressure range. A feedback vibration mode in which at least one of the output amplitude, frequency, or duty cycle changes when any of the contact pressures is outside the corresponding target pressure range. When the cycle operation phase ends, a massage vibration mode is output.
[0013] Furthermore, the controller controls the operation of the corresponding airbag, pressure sensor, and vibration mechanism according to the output mode, performs reference pressure calibration, outputs the corresponding target pressure range and air pressure stage level, and drives the start of the cycle operation stage.
[0014] Furthermore, the vibration mechanism includes: Several vibration motors are respectively disposed below the first airbag portion and the second airbag portion to generate the vibration signal; Several sound-absorbing sponges are connected to several of the aforementioned vibrating motors to absorb the mechanical noise generated by the vibrating motors; Several vibration-damping support layers are connected to several of the aforementioned vibration motors to provide mechanical support for the vibration motors and to block the transmission of vibration.
[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The device of this invention allows the user, while seated, to independently sense the muscle contractions corresponding to the anus, urethra / vagina, and adductor muscles of the thigh. This enables analysis of the overall movement state of the pelvic floor muscles. Traditionally, a single airbag or pressure pad is used to measure pressure at specific locations. The airbag is equipped with a pressure sensor, a vibration motor, and a support structure, allowing for precise understanding of the user's forward / backward and left / right muscle movement patterns. Therefore, it effectively corrects overexertion or underactivation of specific areas. By comparing the user's real-time pressure value with a target pressure range, the device can immediately adjust the movement in the desired direction. When the user's contraction intensity is lower than the target, force is guided by protruding airbags or feedback vibration; when it is higher than the target, relaxation is guided by vibration or voice, thus training to maintain correct contraction intensity. This helps in learning the correct contraction intensity and improves the quality of repeated training. The stacked structure of springs, sound-absorbing foam, and vibration-damping support layers minimizes noise, mechanical interference, and measurement errors caused by the vibration motor. Springs provide the airbags with restoring force while absorbing vibration impact, sound-absorbing foam effectively blocks contact noise between the vibration motor and internal structures, and a vibration-damping support layer prevents vibration from being transmitted to the entire body, thus ensuring that pressure measurements of each airbag section can be performed accurately without interference. This fundamentally solves the problem of pressure measurement errors during vibration stimulation in existing technologies. By providing multiple feedback, including auditory, visual, and tactile feedback, and considering that users in a seated environment often cannot directly look at the display screen, the vibration mode is clearly changed when deviating from the target range, and voice or LED signals are provided during stage transitions, thus enabling intuitive understanding of the movement process. By distinguishing movement modes into anal mode, urethral / vaginal mode, adductor muscle mode, and comprehensive mode, and automatically mapping the combination of sensors, airbags, and vibrations used according to each mode, various muscle group adjustments and coordination training are performed.
[0016] Furthermore, the device of the present invention, by setting up independent first, second, and third airbag sections and equipping them with corresponding first, second, and third pressure sensors, achieves multi-point synchronous pressure sensing of the anal region, urethra / vaginal region, and adductor muscle region. Since the single pressure detection unit in traditional devices is difficult to distinguish the differences in muscle activity at different anatomical locations, it is easy to misjudge the type or intensity of pelvic floor muscle contraction. However, by using a spatially clearly distributed three-zone airbag structure, combined with pressure sensing technology, the device can identify the pressure distribution characteristics of the front, back, left, and right sides, thereby effectively distinguishing the user's actual force application points and avoiding training deviations caused by local compensation, thus improving the accuracy of pelvic floor muscle movement assessment.
[0017] Furthermore, the device of the present invention dynamically sets the corresponding target pressure range according to the selected output mode through the controller, and compares the deviation between the contact pressure of each airbag and the target value in real time, thereby adjusting the inflation volume and contraction intensity of the airbag. When the pressure of a certain area is detected to be lower than the target range, the controller drives the air pump to increase the air pressure of that airbag, so that it protrudes appropriately to enhance the stimulation and guide the user to strengthen the active contraction of the corresponding muscle group. When the pressure exceeds the target range, the air pressure is reduced and vibration, voice or visual feedback is triggered to prompt the user to relax and prevent excessive tension from causing reverse inhibition, thereby improving the effectiveness of the training process.
[0018] Furthermore, the device of the present invention divides each training session into a relaxation phase, an exertion phase, and a holding phase by setting a cyclical operation phase, simulating the clinically recommended standard Kegel exercise rhythm. The controller advances the transition between each phase according to the preset cycle time parameters, and outputs voice prompts or LED light changes through the indicator mechanism at the moment of phase switching, thereby grasping the current training status. Especially in a seated environment, where the user's gaze is often off the display interface, this kind of multimodal prompt can ensure that the operation guidance does not rely on visual focus.
[0019] Furthermore, the device of the present invention outputs differentiated vibration modes through the vibration mechanism. Within the target pressure range, it outputs a low-amplitude, low-frequency relaxation vibration. When the pressure deviates from the target range, it switches to a high-intensity, high-frequency, or pulse-type feedback vibration to create a perceived difference and serve as a prompt.
[0020] Furthermore, the device of the present invention, by setting vibration motors on the surface of each airbag and cooperating with sound-absorbing sponge and vibration-damping support layer, achieves effective transmission of local vibration, avoids cross-regional interference and overall structural resonance, and improves the stability and accuracy of pressure measurement.

The present invention provides a pelvic floor muscle exercise device utilizing pressure sensing and vibration stimulation, comprising: Main body 100, used to provide seating positions; An airbag mechanism, connected to the main body 100, is used to form contact pressure by adjusting air pressure. It includes a first airbag part 200 for protruding and contracting vertically by adjusting a first air pressure to form a first contact pressure; a second airbag part 300, linearly arranged on the main body 100 with the first airbag part 200, for controlling the protrusion height by adjusting a second air pressure to form a second contact pressure; and a third airbag part 400, arranged on the side of the main body 100 away from the first airbag part 200, for forming a third contact pressure. A vibration mechanism, which is connected to the airbag mechanism, is used to output vibration signals; A detection mechanism, connected to the airbag mechanism, is used to detect the first contact pressure, the second contact pressure, and the third contact pressure respectively; The controller 130, connected to the airbag mechanism, the vibration mechanism, and the detection mechanism respectively, is used to determine the corresponding target pressure range according to the output mode, and also to control the contraction intensity of the airbag mechanism, adjust the vibration mode of the vibration mechanism, switch the cycle operation stage, and adjust the vibration mode of the vibration mechanism under any of the output modes based on the comparison result between the contact pressure and the corresponding target pressure range. The cycle operation phases include a relaxation phase, an exertion phase, and a holding phase; the vibration modes include a relaxation vibration mode, a feedback vibration mode, and a massage vibration mode; and the output modes include anal mode, urethral / vaginal mode, adductor muscle mode, and a combined mode.
[0027] Specifically, the airbag protrudes towards the user's pelvic floor when inflated to squeeze against the muscles and detect contact pressure; Each airbag is made of sealed medical-grade silicone or TPU material, and the airbag is also equipped with an interface for connecting to a solenoid valve. The first airbag part 200 is located at the rear of the main body 100 and corresponds to the user's anal area; the second airbag part 300 is located in the middle of the main body 100 and corresponds to the user's urethra / vaginal area; and the third airbag part 400 is located at the front of the main body 100 and corresponds to the user's inner thigh adductor muscles.
[0028] Specifically, in the anal mode, only the first airbag 200, the first pressure sensor 150, and the corresponding vibration motor 350 are activated; in the urethra / vaginal mode, only the second airbag, the second pressure sensor 140, and the corresponding vibration motor 350 are activated; and in the adductor muscle mode, only three airbags, three pressure sensors, and three vibration motors 350 are activated.
[0029] In this embodiment, the pressure between the user and the airbag in a seated state is used as the reference pressure, and a target pressure range is determined. For example, the target pressure range of the first airbag 200 in the anal mode is [8 kPa, 12 kPa], the target pressure range of the second airbag 300 in the urethra / vaginal mode is [6 kPa, 10 kPa], the target pressure range of the third airbag 400 in the adductor mode is [4 kPa, 8 kPa], and the target pressure range of the first airbag 200 in the combined mode is [10 kPa, 14 kPa], the target pressure range of the second airbag 300 is [7 kPa, 11 kPa], and the target pressure range of the third airbag 400 is [5 kPa, 9 kPa]. Each training cycle includes a relaxation phase, an exertion phase, and a hold phase. The relaxation phase lasts 3 to 5 seconds, during which the airbag is in a low-pressure state and the vibration output is in a low-frequency relaxation mode. The exertion phase lasts 2 to 3 seconds, corresponding to the airbag being inflated to the lower limit of the target pressure range. The hold phase lasts 5 to 10 seconds. The phase transition is controlled by a timer and is indicated to the user by voice prompts or LED flashing.
[0030] Specifically, the contraction intensity is the reverse contraction force exerted by the airbag on the user's muscle group, which is achieved by adjusting the airbag pressure through an air pump. When the contact pressure is detected to be lower than the target range, the air pump increases the air pressure of the corresponding airbag, causing it to protrude outward and thus enhancing the mechanical stimulation of the muscle group.
[0031] Specifically, the third airbag section 400 includes two airbags, which are designed in the shape of a long strip or a saddle. The two airbags are respectively located on both sides of the main body 100 and protrude in the horizontal direction.
[0032] In practice, taking the first airbag 200 as an example, the airbag maintains a reference pressure in the initial state. When the user contracts the anal sphincter, the pelvic floor muscles lift up, compressing the airbag above, causing the airbag volume to decrease and the internal pressure to increase. When the user relaxes, the pressure is released, the airbag recovers under the action of the spring 340, and the internal pressure decreases.
[0033] In practice, the device of the present invention allows the user to independently set up a first airbag 200, a second airbag 300, and a third airbag 400 to sense muscle contractions corresponding to the anus, urethra / vagina, and adductor muscles of the thigh while the user is in a seated position. Therefore, it is possible to analyze the overall movement state of the pelvic floor muscles. Traditionally, a single airbag or a single pressure pad is used to measure the pressure of a specific area. By setting up a pressure sensor, a vibration motor 350, and a support structure, the airbag can specifically grasp the user's forward and backward and left and right movement patterns of the muscles. Therefore, it has the advantage of effectively correcting problems such as excessive force or insufficient activation of specific parts by the user. By comparing the user's real-time pressure value with the target pressure range, it can immediately execute the required directional movement adjustment. When the user's contraction intensity is lower than the target, it guides the force by protruding airbags or providing feedback vibration; when it is higher than the target, it relaxes the force through vibration or voice guidance, thereby training to maintain the correct intensity of movement. This helps to learn the correct contraction intensity and improve the quality of repeated training. The stacked structure of spring 340, sound-absorbing foam 310, and vibration-damping support layer 320 minimizes noise, mechanical interference, and measurement errors caused by the vibration motor 350. Spring 340 provides the restoring force of the airbag while absorbing vibration impact, sound-absorbing foam 310 effectively blocks contact noise between the vibration motor 350 and internal structures, and vibration-damping support layer 320 prevents vibration from being transmitted to the entire body 100, thus enabling accurate pressure measurement of each airbag without interference. This fundamentally solves the problem of pressure measurement error during vibration stimulation in existing technologies; by providing multiple feedback including auditory, visual, and tactile feedback, and considering that users in a seated environment often find it difficult to directly look at the display screen, the vibration mode is clearly changed when deviating from the target range, and voice or LED signals are provided during stage transitions, thus enabling intuitive understanding of the movement process; by distinguishing movement modes into anal mode, urethral / vaginal mode, adductor muscle mode, and comprehensive mode, and automatically mapping the combination of sensors, airbags, and vibrations used according to each mode, various muscle group adjustments and coordination training can be carried out.
[0034] Specifically, the testing institutions include: A first pressure sensor 150 is connected to the first airbag portion 200 and is used to detect the first contact pressure; The second pressure sensor 140 is connected to the second airbag portion 300 and is used to detect the second contact pressure; The third pressure sensor 110 is connected to the third airbag portion 400 and is used to detect the third contact pressure.
[0035] Specifically, the airbag mechanism further includes: An air pump is used to supply air to the first airbag section 200, the second airbag section 300, and the third airbag section 400, respectively. Several solenoid valves are connected to the air pump to adjust the air volume of the first airbag section 200, the second airbag section 300 and the third airbag section 400 respectively. Several springs 340 are respectively disposed above several of the solenoid valves to provide a restoring force that causes the airbag to contract during exhaust.
[0036] Specifically, each of the first, second, and third airbags is connected to a solenoid valve, and the interfaces of the three airbags and the corresponding solenoid valves are respectively provided with a first air supply channel 120, a second air supply channel 160, and a third air supply channel 170.
[0037] Specifically, the air pump adjusts the supply flow through the PWM control signal of the controller 130, and the solenoid valve opens to open the exhaust path of the first air supply channel 120, the second air supply channel 160, and the third air supply channel 170 leading to the airbag, thereby controlling the expansion or contraction of the airbag.
[0038] In practice, the device of the present invention, by setting up independent first airbag section 200, second airbag section 300 and third airbag section 400, and respectively equipped with corresponding first pressure sensor 150, second pressure sensor 140 and third pressure sensor 110, realizes multi-point synchronous pressure sensing of the anal area, urethra / vaginal area and adductor muscle area. Since the single pressure detection unit in traditional devices is difficult to distinguish the differences in muscle activity at different anatomical locations, it is easy to misjudge the type or intensity of pelvic floor muscle contraction. However, by using a three-zone airbag structure with a clear spatial distribution, combined with pressure sensing technology, the pressure distribution characteristics of the front and back and left and right sides can be identified, thereby effectively distinguishing the user's actual force application points, avoiding training deviations caused by local compensation, and improving the accuracy of pelvic floor muscle movement assessment.
[0039] Specifically, the controller 130 is connected to a plurality of pressure sensors to control the amount of air that the air pump inputs to the first airbag 200, the second airbag 300 and the third airbag 400 respectively, so that the first contact pressure, the second contact pressure and the third contact pressure reach the corresponding target pressure range respectively.
[0040] Specifically, it also includes an indicator mechanism connected to the controller 130 for outputting visual and voice signals.
[0041] Specifically, the indicating mechanism includes an LED screen and a loudspeaker set on the surface of the main body 100.
[0042] Specifically, the controller 130 is configured to increase the contraction strength when any of the contact pressures is less than the corresponding target pressure range; Under any of the contact pressures being greater than the corresponding target pressure range, the visual signal, the voice signal, and the vibration signal are output respectively.
[0043] In practice, the shrinkage strength is increased by controlling the solenoid valve to open the corresponding air bladder and starting the air pump to inflate it.
[0044] In practice, the device of the present invention dynamically sets the corresponding target pressure range according to the selected output mode through the controller 130, and compares the deviation between the contact pressure of each airbag and the target value in real time, thereby adjusting the inflation volume and contraction intensity of the airbag. When the pressure of a certain area is detected to be lower than the target range, the controller 130 drives the air pump to increase the air pressure of the airbag, so that it protrudes appropriately to enhance the stimulation and guide the user to strengthen the active contraction of the corresponding muscle group. When the pressure exceeds the target range, the air pressure is reduced and vibration, voice or visual feedback is triggered to prompt the user to relax and prevent excessive tension from causing reverse inhibition, thereby improving the effectiveness of the training process.
[0045] Specifically, the controller 130 is used to control the airbag mechanism to operate sequentially according to the relaxation phase, the exertion phase, and the holding phase; Under the conditions of each stage transition, the indicating mechanism is controlled to output the visual signal or the voice signal for indication; Under the conditions of the holding phase, the corresponding vibration output mode and the display color and illumination mode of the visual signal are adjusted according to the deviation between the contact pressure and the corresponding target pressure range.
[0046] Specifically, the deviation is the pressure value that exceeds the corresponding target pressure range when the contact pressure exceeds the target pressure range; In this embodiment, during the holding phase, if the deviation is within ±10%, the vibration mode maintains low-frequency relaxation vibration, and the LED displays a solid green light. If the deviation exceeds ±10%, the vibration switches to a high-frequency prompt mode, and the LED flashes red. If the deviation is below -10%, the vibration switches to a pulse excitation mode, the LED changes to a yellow breathing light mode, and a voice prompt says "Hold" or "Adjust intensity". The LEDs are installed on the side wall of the main body 100.
[0047] In practice, the device of the present invention divides each training session into a relaxation phase, an exertion phase, and a holding phase by setting a cyclical operation phase, simulating the clinically recommended standard Kegel exercise rhythm. The controller 130 advances the transition between each phase according to the preset cycle time parameters, and outputs voice prompts or LED light changes through the indicator mechanism at the moment of phase switching, thereby grasping the current training status. Especially in a seated environment, where the user's eyes are often off the display interface, this kind of multimodal prompt can ensure that the operation guidance does not rely on visual focus.
[0048] Specifically, the controller 130 is connected to the vibration mechanism to output a low-amplitude, low-frequency relaxation vibration mode when any of the contact pressures is within the corresponding target pressure range. A feedback vibration mode in which at least one of the output amplitude, frequency, or duty cycle changes when any of the contact pressures is outside the corresponding target pressure range. When the cycle operation phase ends, a massage vibration mode is output.
[0049] In practice, the vibration frequency of the relaxation vibration mode is 20–40 Hz, the amplitude is 0.5–1 mm, and the duty cycle is 30%–0%; in the feedback vibration mode, when the pressure deviates from the target pressure range, the frequency is adjusted to 60–100 Hz, the amplitude is adjusted to 1.5–3 mm, and / or the duty cycle is adjusted to 70%–90%; in the massage vibration mode, it is started after the training cycle ends, using intermittent vibration with a frequency of 30–80 Hz for 1–2 minutes.
[0050] In practice, the device of the present invention outputs differentiated vibration modes through the vibration mechanism. Within the target pressure range, it outputs a low-amplitude, low-frequency relaxation vibration. When the pressure deviates from the target range, it switches to a high-intensity, high-frequency, or pulse-type feedback vibration to create a perceived difference and serve as a prompt.
[0051] Specifically, the controller 130 controls the operation of the corresponding airbag, pressure sensor and vibration mechanism according to the output mode, performs reference pressure calibration, outputs the corresponding target pressure range and air pressure stage level, and drives the start of the cycle operation stage.
[0052] Specifically, the baseline pressure calibration is performed automatically before each training session begins. During calibration, the user sits on the device, and the controller 130 controls the air pump to inflate each airbag to the initial pressure. In this embodiment, the initial pressure is set to 2 kPa. After 3 seconds, the stable readings of each pressure sensor are recorded as the baseline value. The airbags are then deflated to a relaxed state, ready to enter the training cycle. The calibration process is used to eliminate the influence of factors such as the user's weight and sitting posture on the pressure measurement.
[0053] In this embodiment, the pattern-parameter mapping table shown in Table 1 is adopted.

[0055] Table 2 Mapping Table of Pressure Stage Levels and Target Pressure Increase Specifically, the process of calibrating the reference pressure involves controlling the corresponding pressure sensor to start sampling, for example, sampling at a frequency of 200Hz for 3 seconds, removing peak values from the collected data and calculating the average value, and using the average pressure as the reference pressure.
[0056] Specifically, the vibration mechanism includes: A plurality of vibration motors 350 are respectively disposed below the first airbag portion 200 and the second airbag portion 300 to generate the vibration signal; A plurality of sound-absorbing sponges 310 are respectively connected to a plurality of the aforementioned vibration motors 350 to absorb the mechanical noise generated by the vibration motors 350; Several vibration-damping support layers 320 are connected to several vibration motors 350 respectively, for mechanical support of the vibration motors 350 and to block vibration transmission.
[0057] In this embodiment, the first and second airbag sections, from top to bottom, consist of an airbag wall 330, a pressure sensor, a spring 340, a sound-absorbing sponge 310, a vibration-damping support layer 320, and a vibration motor 350, respectively. No vibration mechanism is provided below the third airbag section 400. Among them, the sound-absorbing sponge 310 is made of polyurethane or EVA material with a porous structure; The airbag wall 330 of the airbag section is provided with a housing for inserting a pressure sensor; The spring 340 is circularly arranged around the pressure sensor, and the top of the spring 340 is provided with an upper plate for supporting the airbag. The vibration damping support layer 320 is made of rubber.
[0058] Specifically, the vibration motor 350 is a BLDC vibration motor 350, which can be replaced by a linear vibration brake. Example
[0059] A single training session in urethral / vaginal mode includes: controller 130 activating the second airbag 300, second pressure sensor 140, and vibration motor 350; performing baseline pressure calibration; entering a relaxation phase for 5 seconds, maintaining airbag pressure at 3 kPa and vibration at 30 Hz; entering a exertion phase for 3 seconds, inflating the airbag to the target range of 8-10 kPa; entering a hold phase for 8 seconds, maintaining low-frequency vibration and a solid green LED if pressure is maintained at 9 kPa ± 1 kPa; switching to high-frequency vibration and flashing red LED if pressure exceeds 11 kPa; and entering massage mode for 1 minute before starting the next cycle or ending the training. Example
[0060] Based on Example 1, the airbag portion in this embodiment can be replaced with an indirect contact airbag portion, wherein... Each airbag generates internal air pressure changes, which drive the injection-molded protrusion structure that houses the vibration motor to move up and down. The airbag does not directly adhere to the user's skin. Through air pressure expansion, it pushes the injection-molded protrusion structure to protrude towards the user's anus, urethra, vagina, or adductor muscles. Specifically, the airbag in the airbag section is made of elastic materials such as TPU and silicone. When inflated, it expands and pushes up the internal protrusion structure. When deflated, it contracts back to its original position through the restoring force of the spring 340 and its own elasticity. The user's contraction and relaxation movements are converted into changes in the adhesion force of the injection-molded protrusion structure. These changes in adhesion force are then converted back into pressure fluctuations inside the airbag, which are quantitatively detected by a pressure sensor.
[0061] In practice, the device of the present invention, by setting vibration motors 350 on the surface of each airbag and cooperating with sound-absorbing sponge 310 and vibration-damping support layer 320, achieves effective transmission of local vibration, avoids cross-regional interference and overall structural resonance, and improves the stability and accuracy of pressure measurement.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
