Description

Technical Field

[0001] This invention relates to the field of medical and nursing rehabilitation assistive devices, and in particular to an assistive reminder device for postoperative Kegel exercises in anorectal surgery. Background Technology

[0002] After surgery for hemorrhoids, anal fissures, perianal abscesses, anal fistulas, and other anorectal conditions, patients are usually required to perform Kegel exercises as prescribed by their doctor to aid in the recovery of perianal muscle function. Kegel exercises need to be performed regularly, correctly, and consistently during the postoperative recovery period. However, postoperative patients often experience pain, fatigue, limited mobility, and memory impairment, making it easy to miss exercise sessions and leading to decreased adherence to rehabilitation exercises.

[0003] Current nursing methods largely rely on verbal reminders from nurses, written education materials, or patients' self-memorization. These reminders are intermittent and fail to consistently correspond to the patient's actual exercise process, making it impossible to determine whether the patient has completed effective Kegel exercises. Nursing staff typically only understand the exercise progress by questioning the patient or reviewing their self-report records, lacking objective counting data that directly reflects the number of effective movements.

[0004] While some assistive devices can detect local physiological changes through pressure, electromyography, or other sensing methods, they still have limitations in the postoperative setting of anorectal surgery. Firstly, the detection components or housing are often located close to the perianal wound. When rigid components directly compress sensitive postoperative areas, they can easily cause pain, friction, or rejection, making them unsuitable for prolonged wear during recovery. Secondly, postoperative movements such as turning over, walking, slight shifts in the strap, or changes in tightness can all cause fluctuations in local pressure. Judging solely by instantaneous pressure levels can easily lead to misinterpreting short-term pressure disturbances as Kegel exercises.

[0005] Meanwhile, the Kegel exercise itself typically involves a gradual increase in pressure, a short period of holding, and then a decrease. If the existing counting method only accumulates pressure when it reaches a threshold, without setting a baseline for relaxation, duration judgment, count locking, and return-to-reset conditions, the same Kegel contraction may be counted repeatedly during its duration, or short-term pressure peaks caused by changes in patient position may be incorrectly counted as valid repetitions, affecting the accuracy of postoperative exercise records.

[0006] Therefore, there is a need to provide a postoperative anal sphincter exercise assistive reminder device and its control system in anorectal surgery. Based on flexible skin-mounted detection and external arrangement of rigid electrical control components, it can sample and process pressure signals, determine baselines, calculate pressure changes, determine effective movements, lock counts, and control reminder outputs, thereby completing the timed reminders and effective movement counting for postoperative anal sphincter exercises. Summary of the Invention

[0007] In view of this, embodiments of the present invention provide an auxiliary reminder device for postoperative Kegel exercises in anorectal surgery. By placing a flexible pressure sensor on the inner surface of the wearable strap and a sensing box on the outer surface of the wearable strap, and arranging the two opposite to each other on the wearable strap, the flexible pressure sensor fits against the outer muscles of the patient's perineum to collect pressure signals. The sensing box carries control and display components but does not directly compress the detection and contact area, thereby solving the problems of postoperative patients easily forgetting Kegel exercises, difficulty in counting effective movements, and discomfort from wearing rigid detection components.

[0008] The technical solution of this invention is implemented as follows: a postoperative anal sphincter exercise assistance and reminder device for anorectal surgery, comprising: The wearing strap is an external wearing structure with adjustable buckles on both sides to fix the device to the patient's waist and hips; The sensor box is fixedly installed on the outer surface of the middle part of the wearing strap; A flexible pressure sensor is fixedly installed on the inner surface of the wearing strap and is positioned opposite to the sensing box on the wearing strap. It is used to conform to the outer muscles of the patient's perineum to collect pressure signals when the anal sphincter contracts. The control board is fixedly installed inside the sensor box and is used to process pressure signals and control the reminder and counting functions; The reminder and interaction unit is fixedly mounted on the sensor box and electrically connected to the control motherboard. The reminder and interaction unit includes a vibration motor for generating timed vibration reminders, a counting display screen for displaying the number of effective Kegel exercises in real time, and operation buttons for setting parameters and turning the device on and off. The control motherboard is used to receive pressure signals from the flexible pressure sensor, identify effective anal sphincter contractions, and drive the counting display to accumulate counts. It is also used to set a timed reminder and drive the vibration motor to send a reminder signal.

[0009] As an improvement, the wearable strap is made of medical-grade elastic silicone material and forms a wraparound wearing structure along its length.

[0010] As an improvement, the flexible pressure sensor is a thin, flexible silicone-wrapped structure, and the flexible pressure sensor is embedded in the inner side of the wearable strap, with its outer surface flush with the inner surface of the wearable strap.

[0011] As an improvement, a power supply battery is also included, which is fixedly installed inside the sensor box and electrically connected to the control motherboard.

[0012] As an improvement, the induction box is a closed waterproof housing with a waterproof charging interface on its side wall that is electrically connected to the power supply battery.

[0013] As an improvement, the power supply battery is a miniature rechargeable lithium battery with a capacity of 100-500mAh.

[0014] As an improvement, the sensor box is fixed to the outer surface of the wearing strap by means of adhesive or snap-on connection.

[0015] A postoperative anal sphincter contraction exercise auxiliary reminder and control system for anorectal surgery is applied to an anal sphincter contraction exercise auxiliary reminder device after anorectal surgery. The control system includes a signal acquisition unit, a parameter setting unit, an action recognition unit, a counting control unit, a reminder control unit, and a display control unit. The signal acquisition unit is connected to the flexible pressure sensor and is used to receive the pressure signal output by the flexible pressure sensor and generate pressure sampling data. The parameter setting unit is connected to the operation buttons and is used to receive power on / off commands, reminder time setting commands, and count reset commands, and generate corresponding control parameters. The action recognition unit is connected to the signal acquisition unit and is used to determine the pressure change state based on the pressure sampling data, and compare the pressure change state with the preset valid action judgment conditions to generate a valid anal sphincter action judgment result. The counting control unit is connected to the action recognition unit and is used to generate a count accumulation signal when the effective anal contraction action determination result indicates that an effective anal contraction action has been completed, and to maintain the count lock state during the period when the same pressure signal continuously reaches the standard, until the pressure sampling data falls back to the relaxation determination range and the count lock state is released. The reminder control unit is connected to the parameter setting unit and is used to generate a timing control state according to the reminder time setting command, and output a reminder drive signal to the vibration motor when the set reminder time is reached. The display control unit is connected to the counting control unit and the counting display screen respectively, and is used to generate display data of the current effective number of Kegel exercises based on the counting accumulation signal, and output the display data of the current effective number of Kegel exercises to the counting display screen.

[0016] Compared with the prior art, the present invention has the following advantages: Compared with the prior art, the present invention has the following advantages: This invention uses a wearable strap as the external base for the patient's waist and hips. A flexible pressure sensor is placed on the inner surface of the middle part of the strap, and the flexible pressure sensor is aligned with the outer muscles of the patient's perineum to collect pressure signals during anal sphincter contraction. Simultaneously, a sensor box is placed on the outer surface of the middle part of the strap, allowing the control board, power battery, and reminder and interaction units to be centrally mounted on the patient's outer side. This combination of inner flexible detection and outer electrical control installation separates the pressure acquisition location from the rigid electrical control component installation location, reducing direct pressure from the rigid shell on sensitive postoperative areas and providing a stable wearing base for subsequent pressure signal acquisition and control processing.

[0017] The control system of this invention receives pressure signals from a flexible pressure sensor via a signal acquisition unit and generates pressure sampling data. The action recognition unit determines a pressure baseline for the relaxed state based on the pressure sampling data, then compares the current pressure sampling data with the relaxed state pressure baseline to generate a pressure change. This change is then combined with a preset pressure change threshold and a preset duration condition to generate a valid anal sphincter contraction action determination result. Through this process, the control board does not count based solely on instantaneous pressure values, but rather identifies anal sphincter contractions based on the pressure change and its duration, thus reducing the impact of short-term pressure fluctuations caused by turning over, walking, or slight shifts in the straps on action recognition.

[0018] The counting control unit of this invention generates a count accumulation signal after receiving the result of a valid Kegel exercise determination, and maintains a count lock state during the period when the same pressure signal continuously meets the standard. When the pressure sampling data is lower than the preset relaxation threshold or falls back to the relaxation determination range, the counting control unit releases the count lock state and enters the next recognition state. Through this counting trigger, locking, and reset processing link, the same Kegel contraction process corresponds to only one count accumulation, avoiding the repeated counting of valid Kegel exercises by continuously meeting the standard pressure signal.

[0019] The parameter setting unit of this invention receives the reminder time setting command input by the operation button and generates reminder time control parameters. The reminder control unit performs timing according to the reminder time control parameters and outputs a reminder drive signal to the vibration motor when the set reminder time is reached. The display control unit generates display data of the current number of effective Kegel exercises based on the counting accumulation signal output by the counting control unit and outputs it to the counting display screen. Through the data connection between reminder control, action recognition, counting control and display control, the device can unify the reminder process and effective action recording process of postoperative Kegel exercises into the same control motherboard.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-2 As shown in the figure, this embodiment of the invention provides a postoperative anal sphincter exercise assistance and reminder device for anorectal surgery, including a wearable strap 1, a sensor box 2, a flexible pressure sensor 3, a control motherboard 4, a reminder and interaction unit 5, a power supply battery 6, and a waterproof charging interface 7. The wearable strap 1 serves as the base for wearing the device, the sensor box 2 serves as the mounting base for the electronic control components, the flexible pressure sensor 3 serves as the component for collecting pressure during anal sphincter exercises, the control motherboard 4 serves as the component for receiving, judging, and outputting control signals, the reminder and interaction unit 5 serves as the component for reminding, displaying, and inputting parameters, and the power supply battery 6 supplies power to the control motherboard 4, the flexible pressure sensor 3, and the reminder and interaction unit 5.

[0027] In this embodiment, the wearing strap 1 is made of medical-grade elastic silicone material. The wearing strap 1 forms a band-like structure along its length that can be worn around the corresponding areas of the patient's waist, hips, and perineum. Adjustable buckles 11 are provided on both sides of the wearing strap 1. These buckles 11 are used to connect the two ends or side connecting sections of the wearing strap 1, allowing the wearing strap 1 to be adjusted in length according to the patient's body shape. When worn, the middle of the wearing strap 1 is located in the area corresponding to the muscles on the outer side of the patient's perineum, and the two sides of the wearing strap 1 wrap around the patient's waist and hips. After the adjustable buckles 11 are locked, the wearing strap 1 is held in the set position.

[0028] The sensor box 2 is fixedly mounted on the outer surface of the middle part of the wearable strap 1, and the flexible pressure sensor 3 is fixedly mounted on the inner surface of the middle part of the wearable strap 1. The sensor box 2 and the flexible pressure sensor 3 are located on both sides of the wearable strap 1 and are arranged opposite to each other in the thickness direction of the wearable strap 1. This arrangement ensures that the sensor box 2 is not directly located at the pressure contact point between the patient's skin and the rigid box body; the patient's body comes into contact with the flexible pressure sensor 3 and its surrounding flexible strap on the inner surface of the wearable strap 1.

[0029] The flexible pressure sensor 3 is a thin, flexible silicone-encased structure. It is embedded in the inner surface of the wearable strap 1, with its outer surface flush with the inner surface of the strap 1. When worn, the flexible pressure sensor 3 conforms to the lateral perineal muscles of the patient, without penetrating the perianal wound area or pressing against the surrounding tissue of the postoperative wound with a rigid structure. When the patient performs Kegel exercises, the lateral perineal muscles contract, generating local pressure changes. These pressure changes act on the flexible pressure sensor 3, which converts the pressure changes into a pressure signal and outputs it to the control motherboard 4.

[0030] The sensor box 2 is a closed, waterproof housing, fixed to the outer surface of the middle part of the wearable strap 1. The sensor box 2 can be fixed to the outer surface of the wearable strap 1 by adhesive or snap-fit ​​connection. The interior of the sensor box 2 forms an installation space for accommodating the control board 4 and the power supply battery 6. The control board 4 is fixedly installed inside the sensor box 2, and the power supply battery 6 is fixedly installed inside the sensor box 2 and electrically connected to the control board 4. The power supply battery 6 is a miniature rechargeable lithium battery with a capacity of 100mAh to 500mAh. A waterproof charging port 7 is located on the side wall of the sensor box 2 and is electrically connected to the power supply battery 6 for charging the battery 6.

[0031] The flexible pressure sensor 3 is electrically connected to the control mainboard 4. Since the flexible pressure sensor 3 and the sensing box 2 are arranged opposite each other on the wearable strap 1, the signal output terminal of the flexible pressure sensor 3 is led from its mounting area to the inside of the sensing box 2 and connected to the pressure signal input terminal on the control mainboard 4. Thus, the pressure acquisition position is located inside the wearable strap 1, and the signal processing position is located inside the sensing box 2 outside the wearable strap 1. The inner skin contact detection and the outer electrical control are installed in the same central area to complete the coordination.

[0032] The reminder and interaction unit 5 is fixedly mounted on the sensing box 2 and electrically connected to the control main board 4. The reminder and interaction unit 5 includes a vibration motor 51, a counting display screen 52, and operation buttons 53. The vibration motor 51 is fixedly mounted on or within the sensing box 2 at a corresponding position and is electrically connected to the reminder output terminal of the control main board 4. The counting display screen 52 is located on the outer surface of the sensing box 2 and is electrically connected to the display output terminal of the control main board 4. The operation buttons 53 are located on the outer surface of the sensing box 2 and are electrically connected to the button input terminal of the control main board 4. Patients or caregivers can turn the device on or off using the operation buttons 53 and set the Kegel exercise reminder time; the counting display screen 52 displays the number of effective Kegel exercises; and the vibration motor 51 generates vibration when the set reminder time is reached.

[0033] During assembly, the flexible pressure sensor 3 is first fixed to the inner surface of the middle part of the wearable strap 1, ensuring that the skin-contact surface of the flexible pressure sensor 3 is flush with the inner surface of the wearable strap 1. Then, the sensor box 2 is fixed to the outer surface of the middle part of the wearable strap 1, so that the sensor box 2 and the flexible pressure sensor 3 are opposite each other on the wearable strap 1. The control main board 4 and the power supply battery 6 are installed inside the sensor box 2. The vibration motor 51, the counting display screen 52, and the operation buttons 53 are electrically connected to the control main board 4, and the waterproof charging interface 7 is electrically connected to the power supply battery 6. After assembly, the wearable strap 1 provides fit and positioning, the sensor box 2 houses the electronic control components, and the flexible pressure sensor 3 collects skin-contact pressure.

[0034] In use, the patient or caregiver places the inner surface of the wearing strap 1 towards the patient's body, aligning the flexible pressure sensor 3 with the lateral perineal muscles. The strap 1 is then wrapped around the patient's waist and hips, and the tightness is adjusted using the buckle 11. After adjustment, the flexible pressure sensor 3 fits snugly against the lateral perineal muscles, and the sensor box 2 is located on the outer surface of the wearing strap 1, not directly clamped between the patient's skin and the detection point. In this wearing state, the flexible pressure sensor 3 can sense local pressure changes caused by anal sphincter contraction. The control board 4, power supply battery 6, and the counting display screen 52 and operation buttons 53 on the sensor box 2 are in an externally operable position.

[0035] When the device is turned on, the patient or caregiver presses the operation button 53, and the control motherboard 4 enters the working state. After setting the Kegel exercise reminder time via the operation button 53, the control motherboard 4 starts timing according to the set parameters. The counting display screen 52 displays the current number of effective Kegel exercises; initially, it can display zero or the count value after the last reset. When the set reminder time is reached, the control motherboard 4 outputs a drive signal to the vibration motor 51, and the vibration motor 51 vibrates. The vibration is transmitted to the wearing site through the sensor box 2 and the wearing strap 1, prompting the patient to perform Kegel exercises.

[0036] When the patient performs Kegel exercises, the muscles on the outer side of the perineum contract, increasing the local pressure on the flexible pressure sensor 3. The flexible pressure sensor 3 generates a pressure signal from this pressure change and transmits it to the control motherboard 4. Upon receiving the pressure signal, the control motherboard 4 compares it with preset valid action criteria. When the pressure signal meets the valid action criteria, the control motherboard 4 determines that one valid Kegel exercise has been completed and drives the counting display screen 52 to increment the count. During the duration of the same Kegel contraction, the control motherboard 4 maintains the counting state for that exercise and does not repeatedly count pressure signals that are continuously in the qualifying state; when the pressure signal returns to the relaxed state, the control motherboard 4 enters the next action recognition state.

[0037] When the patient turns over, walks, or experiences slight displacement of the support band 1, the flexible pressure sensor 3 may also generate short-term pressure fluctuations. The control board 4 filters the pressure signals based on valid action criteria, counting only when the pressure change meets the target state corresponding to anal sphincter contraction. Therefore, transient interference signals caused by daily changes in body position will not directly cause the counting display screen 52 to accumulate and display.

[0038] After use, the patient or caregiver can turn off the device using button 53. Because the sensor box 2 is a sealed, waterproof casing, and the control board 4 and power supply battery 6 are located inside the sensor box 2, patient sweat or nursing wipes are unlikely to enter the sensor box 2 during daily use. The device surface can be wiped clean while the device is closed. When the power supply battery 6 is low on power, it can be charged through the waterproof charging port 7 on the side wall of the sensor box 2.

[0039] like Figure 3 As shown, this embodiment further describes the anorectal surgery post-operative Kegel exercise auxiliary reminder control system in the control motherboard 4, based on the aforementioned device structure. The control system processes and controls the pressure signal output by the flexible pressure sensor 3, the control commands input by the operation buttons 53, the reminder drive signal from the vibration motor 51, and the display data on the counting display screen 52. The control system includes a signal acquisition unit, a parameter setting unit, an action recognition unit, a counting control unit, a reminder control unit, and a display control unit. Each of these units can be implemented by the microcontroller, storage circuit, analog-to-digital converter circuit, button input circuit, motor drive circuit, and display drive circuit on the control motherboard 4.

[0040] The signal acquisition unit is connected to the flexible pressure sensor 3. When the patient performs Kegel exercises, the contraction of the lateral perineal muscles causes a change in the local pressure on the flexible pressure sensor 3. The flexible pressure sensor 3 outputs a pressure signal corresponding to this pressure change. The signal acquisition unit samples the pressure signal according to a preset sampling period to form pressure sampling data. Let the first... Each sampling time is The pressure sampling value corresponding to this sampling time is The pressure sampling data is then represented as: in, Indicates the first One pressure sampling data, Indicates the sampling time. This indicates the pressure value output by the flexible pressure sensor 3 at the sampling moment. When the flexible pressure sensor 3 outputs an analog voltage signal, the signal acquisition unit converts the analog voltage signal into a digital pressure value through an analog-to-digital converter circuit; when the flexible pressure sensor 3 outputs a digital signal, the signal acquisition unit reads the corresponding digital pressure value as the pressure sampling value. .

[0041] To reduce the impact of momentary jitter on action determination, the signal acquisition unit can perform a moving average processing on the continuous pressure sample values. Let the moving window length be... Then the first Smoothed pressure value at each sampling time for: in, A positive integer, used to limit the number of consecutive sampling points participating in the smoothing process. Subsequent action recognition can use the pressure sampling value. Alternatively, a smoothed pressure value can be used. In this embodiment, for ease of explanation, a smoothed pressure value is used. As input for action recognition.

[0042] The parameter setting unit is connected to the operation button 53. Patients or caregivers input power-on / off commands, reminder time setting commands, and count reset commands via the operation button 53. Upon receiving the power-on / off command, the parameter setting unit controls the main control board 4 to enter either a working or stopped state; upon receiving the reminder time setting command, it writes the reminder interval or reminder time into the storage area of ​​the main control board 4 and generates reminder time control parameters; upon receiving the count reset command, it generates count initialization parameters to restore the current effective number of anal sphincter contractions to the initial value.

[0043] The motion recognition unit is connected to the signal acquisition unit and is used to identify valid Kegel exercises based on pressure sampling data. The motion recognition unit includes a baseline determination subunit, a pressure change calculation subunit, and a valid motion determination subunit.

[0044] After the device is turned on and worn, the baseline determination subunit reads multiple consecutive pressure sampling data points when the patient is not performing anal sphincter contractions to determine the pressure baseline in the relaxed state. Let the number of sampling points used to determine the pressure baseline in the relaxed state be... The baseline pressure in the relaxed state It can be represented as: in, Indicates the baseline pressure in a relaxed state. This indicates the number of sampling points selected during the baseline determination phase. Indicates the first A smoothed pressure value. Alternatively, a relaxed state pressure baseline. Alternatively, the median of multiple consecutive smoothed pressure values ​​can be used to reduce the impact of individual abnormal sampling points on the baseline.

[0045] The pressure change calculation subunit reads the current smoothed pressure value. and compared it with the relaxation state pressure baseline. Compare and generate pressure change. : in, Indicates the first The pressure change at each sampling point relative to the baseline pressure in the relaxed state. When there are differences in the tightness of the garment or the initial fit pressure among different patients, the pressure change calculation subunit can also generate a normalized pressure change. : in, This represents the normalized change in pressure. This is a preset non-zero protection value used to avoid the denominator being zero. The action recognition unit can be selected. or Both can be used simultaneously as criteria for determining a valid action.

[0046] The effective action determination subunit compares the pressure change with a preset pressure change threshold and records the duration after the pressure change reaches the preset pressure change threshold. Let the preset pressure change threshold be... The preset duration threshold is The pressure change reached for the first time The sampling time is The current duration of compliance Represented as: When both the pressure change and duration satisfy the following formula, the effective action determination subunit generates an effective anal sphincter movement determination result. : in, This indicates that the current sampling phase meets the criteria for determining a valid Kegel exercise. This indicates that the current sampling phase does not meet the criteria for valid Kegel exercises. By simultaneously setting a pressure change threshold and a duration threshold, the action recognition unit can distinguish between short-term pressure fluctuations and continuous changes in Kegel contraction pressure.

[0047] The counting control unit is connected to the action recognition unit and is used to control the counting based on the determination of valid Kegel exercises. The counting control unit includes a counting trigger subunit, a counting lock subunit, and a counting reset judgment subunit. Let the current number of valid Kegel exercises be... The count lock state is ,in Indicates counter locking. This indicates that the next count can be triggered. When the action recognition unit outputs a valid anal sphincter movement determination result, and the counting control unit is in an unlocked state, the counting trigger subunit generates a count accumulation signal: After generating a count accumulation signal, the counting lock subunit sets the count lock state to the locked state, so that the pressure sampling data that continuously meets the target during the same Kegel contraction process will not trigger the count again: The counting reset judgment subunit continuously reads the pressure sampling data and compares the pressure change with a preset relaxation threshold. Let the preset relaxation threshold be... ,and When the pressure change falls below the preset relaxation threshold, the counter reset judgment subunit releases the counter lockout state. Therefore, a complete Kegel exercise corresponds to only one count trigger; only after the pressure signal falls back to the relaxation judgment range will the counting control unit enter the next valid Kegel exercise recognition state.

[0048] The reminder control unit is connected to the parameter setting unit. The parameter setting unit generates the reminder interval based on the reminder time setting command input via operation button 53. The control unit is reminded to record the last reminder output time. At the current moment When the difference between the current time and the last reminder output time reaches the reminder interval, the reminder control unit generates a reminder drive signal. : in, This indicates that the control unit outputs a reminder drive signal to the vibration motor 51. This indicates that no reminder drive signal will be output. When... When the time comes, the control unit drives the vibration motor 51 to vibrate and updates the last reminder output time to the current time. The reminder drive signal can be a continuous drive signal or an intermittent drive signal; when an intermittent drive signal is used, the reminder control unit controls the vibration motor 51 to start and stop according to the preset number of vibrations and the preset vibration interval.

[0049] The display control unit is connected to both the counting control unit and the counting display screen 52. Each time the counting control unit generates a count accumulation signal, it updates the current number of valid anal sphincter contractions. The data is sent to the display control unit. The display control unit converts the current number of valid Kegel exercises into display data that can be shown on the counting display screen 52. : in, This indicates the current display data output to the counting display screen 52. If the parameter setting unit receives a count reset command, the counting control unit will... When the count is set to zero, the display control unit synchronously outputs the initial count display data.

[0050] In a specific control process, after the device is turned on, the parameter setting unit receives the reminder time setting command input by the operation button 53 and generates reminder time control parameters; the signal acquisition unit receives the pressure signal output by the flexible pressure sensor 3 and forms pressure sampling data according to the preset sampling period. The pressure sample values ​​were then smoothed to obtain... The motion recognition unit determines the relaxation state pressure baseline based on continuous pressure sampling data after the device is worn. The pressure change was calculated when the patient performed Kegel exercises. .when Reaching the preset pressure change threshold And the duration of compliance Reaching the preset duration threshold At that time, the action recognition unit generates a valid Kegel exercise determination result. The counting control unit is in And the count is locked. A count accumulation signal is generated periodically, incrementing the current effective number of Kegel exercises by one and locking the count. The display control unit controls the count display screen 52 to show the updated number of effective Kegel exercises. (Pending pressure change) Return to the preset relaxation threshold At this point, the counting control unit releases the counting lock and waits for the result of the next valid Kegel exercise. The reminder control unit then activates the reminder at intervals. It operates independently and outputs a reminder drive signal to the vibration motor 51 when the set reminder time is reached.

[0051] When the patient turns over, walks, or experiences slight displacement of the compression band 1, the flexible pressure sensor 3 may generate short-term pressure fluctuations. For such pressure fluctuations, the motion recognition unit still determines the outcome based on two conditions: the magnitude of the pressure change and its duration. If the magnitude of the pressure change does not reach the preset pressure change threshold... Or, although the preset pressure change threshold is reached However, the duration did not reach the preset duration threshold. The result of the valid action determination is: The counting control unit does not generate a count accumulation signal, and the display control unit does not update the current number of valid Kegel exercises.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
