Description

[0001] This invention patent application is a divisional application of the invention patent application with application number 202110309924.X and application date March 23, 2021. Technical Field

[0002] The present invention relates to the technical field of medical care, and in particular to a method for detecting female pelvic floor muscle pressure. Background Art

[0003] The female pelvic floor muscles are the muscles that seal the pelvic floor. These muscles surround organs such as the urethra, bladder, uterus, and rectum, supporting the pelvic and abdominal organs and maintaining their normal position for proper function. Therefore, the pelvic floor muscles are involved in bladder, bowel, and sexual function. They can be damaged by infection, inflammation, trauma, or excessive tearing, such as that caused by childbirth. Damage to the pelvic floor muscles reduces their elasticity, which can lead to an inability to maintain the normal position of the associated organs, resulting in functional impairments such as dysuria, cystitis, pelvic organ prolapse, sexual dysfunction, and chronic discomfort.

[0004] In clinical practice, testing the contractility of a woman's pelvic floor muscles is necessary to determine the extent of damage or recovery after treatment, allowing doctors to assess and determine treatment plans. Furthermore, for patients whose pelvic floor muscles have become lax due to childbirth or age, testing their contractility is also necessary when using pelvic floor exercise equipment to assess their recovery and provide targeted training. Typically, testing the contractility of the pelvic floor muscles can be performed using pressure sensors placed in appropriate locations within the human body. For example, a thin-film pressure sensor can be mounted on a carrier and then placed in an appropriate location within the female body. The pressure applied to the sensor is then measured to determine the contractility of the pelvic floor muscles. Common carriers for thin-film pressure sensors include Kegel balls or vibrating devices used for pelvic floor exercise. This method allows for real-time monitoring of the contractility of the pelvic floor muscles.

[0005] UK Patent Application No. 1111532.6 teaches an electronic posture sensor that responds to the squeezing, positioning, or movement of the device itself. The device can be inserted into the pelvic cavity and detects and responds to the movement of the wearer and the feedback device. However, the electronic device provided in this patent has several drawbacks: First, the electronic device must first detect the user's feedback device via a sensor and then use its vibration motor to remind the user to adopt a better posture. Therefore, the electronic device disclosed in this patent can only provide a reminder and cannot directly detect the contraction ability of the pelvic floor muscles and provide direct detection results to the user. Second, the electronic device can only play a role in strengthening the patient's pelvic floor muscles if the patient successfully tightens the corresponding muscles. Therefore, the electronic device only works through the vibration therapy of its vibration motor and cannot provide the user with pelvic floor muscle contraction force detection results to guide and help the user to exercise their pelvic floor muscles. Finally, the electronic device can only obtain a vague and non-quantitative posture signal.

[0006] Chinese invention patent application number CN201410751835.0 provides a female pelvic floor muscle pressure detection device, which can detect the contraction ability of the user's pelvic floor muscles through its thin film pressure sensor and help the user exercise the pelvic floor muscles based on the detection results. The thin film pressure sensor used in the female pelvic floor muscle pressure detection device is a resistive sensor. The thin film pressure sensor is attached to a carrier and placed in an appropriate position in the human body. Its output resistance decreases as the pressure applied to the surface of the thin film pressure sensor increases. The thin film pressure sensor is connected to an analog-to-digital conversion module via a voltage amplifier circuit. By detecting the change in the resistance of the thin film pressure sensor and the resistance-pressure relationship of the thin film pressure sensor, the pressure applied to the surface of the thin film pressure sensor is detected. However, although the resistance of the thin film pressure sensor changes monotonically with the pressure applied to it, the corresponding relationship between the resistance of the thin film pressure sensor and the pressure is not linear, but nonlinear. In other words, when the pressure applied to the thin film pressure sensor is small, the resistance changes significantly with the pressure change, while when the pressure applied is large, the resistance changes relatively little with the pressure change. Therefore, when the pressure applied to the thin film pressure sensor is low, the resistance changes too much with pressure, while when the pressure applied is high, the resistance changes too little with pressure. As a result, whether the pressure applied to the thin film pressure sensor is too low or too high, accurately detecting the pressure by measuring the resistance of the thin film pressure sensor is difficult. Furthermore, when the pressure applied to the thin film pressure sensor is low, the resistance changes too much with pressure, while when the pressure applied is high, the resistance changes too little with pressure. This also results in a narrow pressure range when measuring the resistance of the thin film pressure sensor to detect the pressure applied to the thin film pressure sensor. Summary of the Invention

[0007] The primary advantage of the present invention lies in providing a method for detecting female pelvic floor muscle pressure. This method converts the resistance signal of a thin film pressure sensor used to detect female pelvic floor muscle pressure into an oscillation frequency signal of a corresponding oscillator. This allows the pressure acting on the thin film pressure sensor to be determined by detecting the oscillation frequency of the multivibrator. Consequently, the present method overcomes the drawback of detecting the pressure acting on a thin film pressure sensor by detecting its resistance.

[0008] Another advantage of the present invention is a method for detecting female pelvic floor muscle pressure. The method comprises connecting a thin film pressure sensor used to detect female pelvic floor muscle pressure to a multivibrator and configuring the multivibrator so that its oscillation frequency varies monotonically (increases or decreases monotonically) as the resistance of the thin film pressure sensor decreases. This allows the oscillation frequency of the multivibrator to correspond to the pressure applied to the thin film pressure sensor. It will be appreciated that the resistance of the thin film pressure sensor varies monotonically (increases or decreases monotonically) as the pressure applied to the thin film pressure sensor changes.

[0009] Another advantage of the present invention is a method for detecting female pelvic floor muscle pressure. The method connects a thin film pressure sensor used to detect female pelvic floor muscle pressure to a multivibrator, configures the multivibrator so that its oscillation frequency increases monotonically as the resistance of the thin film pressure sensor decreases, and establishes a substantially linear relationship between the oscillation frequency of the multivibrator and the pressure sensed by the thin film pressure sensor. This expands the upper and lower limits of the detection range of female pelvic floor muscle pressure and enhances the accuracy of pelvic floor muscle pressure detection. Accordingly, the method can detect a wider range of pressure values ​​and smaller pressure value variations.

[0010] Another advantage of the present invention is that it provides a method for detecting female pelvic floor muscle pressure, wherein the method for detecting female pelvic floor muscle pressure of the present invention can determine the pressure (or contraction force) of the pelvic floor muscle exerted on the thin film pressure sensor corresponding to the oscillation frequency of the multivibrator through the oscillation frequency of the multivibrator, so that the pressure can be provided to the user visually, thereby allowing the user to conveniently obtain the pressure of the detected pelvic floor muscle.

[0014] (B) detecting the oscillation frequency of the multivibrator, and obtaining the pressure value of the thin film pressure sensor based on the corresponding relationship between the oscillation frequency of the multivibrator and the pressure of the thin film pressure sensor.

[0037] The following description is provided to enable those skilled in the art to implement the present invention. Those skilled in the art may conceive of other obvious replacements, modifications, and variations. Therefore, the scope of protection of the present invention should not be limited by the exemplary embodiments described herein.

[0038] Those skilled in the art should understand that, unless otherwise specified herein, the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple.

[0039] Those skilled in the art should understand that, unless otherwise specified herein, the directions or positions referred to by terms such as "longitudinal," "transverse," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are based on the directions or positions shown in the accompanying drawings and are merely for the purpose of facilitating the description of the present invention. They do not indicate or imply that the devices or components involved must have a specific direction or position. Therefore, the above terms should not be construed as limiting the present invention.

[0040] Figures in the specification Figure 1 The figure shows the resistance-pressure (value) variation curve of the thin film pressure sensor for detecting the female pelvic floor muscle pressure according to an exemplary embodiment of the present invention. Figure 1 As shown, the resistance of most existing thin-film pressure sensors used to detect female pelvic floor muscle pressure decreases monotonically with increasing pressure. However, the resistance of these thin-film pressure sensors varies nonlinearly with pressure: when the pressure is low, the resistance changes significantly with pressure, while when the pressure is high, the resistance changes relatively little. Accordingly, when the pressure is low, the resistance changes significantly with pressure, while when the pressure is high, the resistance changes slightly with pressure. Consequently, regardless of whether the pressure is too low or too high, accurately detecting the pressure by measuring the resistance of the thin-film pressure sensor and using the detected resistance is difficult. Furthermore, when the pressure is low, the resistance changes significantly with pressure, while when the pressure is high, the resistance changes slightly with pressure. This results in a narrow pressure range when detecting the pressure by measuring the resistance of the thin-film pressure sensor. Therefore, the traditional pressure detection method of determining the pressure applied to the thin film pressure sensor by detecting the resistance of the thin film pressure sensor cannot accurately detect the pressure applied to the thin film pressure sensor, and the pressure range that can be detected is also relatively small.

[0041] To improve the pressure detection accuracy and maximize the pressure detection range of a thin film pressure sensor used to detect female pelvic floor muscle pressure, the present invention creatively develops a new method for detecting the pressure experienced by a thin film pressure sensor: by connecting the thin film pressure sensor to a multivibrator and configuring the multivibrator so that the oscillation frequency of the multivibrator corresponds to the pressure experienced by the thin film pressure sensor, and then detecting the oscillation frequency of the multivibrator to determine the magnitude of the pressure experienced by the thin film pressure sensor. Accordingly, when using the female pelvic floor muscle pressure detection system of the present invention to detect female pelvic floor muscle pressure, the pressure experienced by the thin film pressure sensor is no longer detected by measuring the resistance of the thin film pressure sensor and determining the magnitude of the pressure experienced based on the resistance of the thin film pressure sensor, but rather by detecting the oscillation frequency of the multivibrator. The female pelvic floor muscle pressure detection system of the present invention can significantly improve the pressure detection accuracy of the thin film pressure sensor and increase its pressure detection range.

[0042] It is worth noting that the exemplary multivibrator for detecting female pelvic floor muscle pressure according to the embodiment of the present invention needs to be pre-configured. First, when the exemplary thin film pressure sensor for detecting female pelvic floor muscle pressure according to the embodiment of the present invention is subjected to different pressures, the resistance (size) of the thin film pressure sensor is determined to change with the pressure, thereby determining the resistance-pressure correspondence of the thin film pressure sensor and obtaining the resistance-pressure change curve of the thin film pressure sensor. As shown in the accompanying figure Figure 1 As shown in the figure, the resistance-pressure variation curve of the thin film pressure sensor for detecting the pressure of the female pelvic floor muscles according to the exemplary embodiment of the present invention is shown. The resistance of the thin film pressure sensor decreases monotonically with the increase of pressure, and the change of its resistance with pressure is nonlinear. It can be understood that the resistance-pressure variation curve of the thin film pressure sensor for detecting the pressure of the female pelvic floor muscles according to the exemplary embodiment of the present invention may vary due to differences in model, preparation material, manufacturing process and even manufacturer. Therefore, the figure Figure 1 Shown is a resistance-pressure curve for an exemplary thin-film pressure sensor for detecting female pelvic floor muscle pressure according to an embodiment of the present invention. When using other types or categories of thin-film pressure sensors, their resistance-pressure curves may vary accordingly. Then, based on the above-described resistance-pressure curve for an exemplary thin-film pressure sensor for detecting female pelvic floor muscle pressure according to an embodiment of the present invention, a multivibrator is configured so that the oscillation frequency of the multivibrator varies monotonically with changes in the resistance of the thin-film pressure sensor, thereby causing the pressure applied to the thin-film pressure sensor to correspond to the oscillation frequency of the multivibrator. Preferably, the multivibrator is configured so that the oscillation frequency of the multivibrator decreases monotonically with increases in the resistance of the thin-film pressure sensor. More preferably, the equation corresponding to the resistance-oscillation frequency curve of the multivibrator and the equation corresponding to the resistance-pressure curve of the thin-film pressure sensor form a generating equation pair. Accordingly, when the exemplary multivibrator for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is configured so that the resistance-oscillation frequency variation curve of the multivibrator and the resistance-pressure variation curve of the thin film pressure sensor are located in the same quadrant, and the resistance-oscillation frequency variation curve of the multivibrator can "coincide" with the resistance-pressure variation curve of the thin film pressure sensor after being shifted an appropriate distance, the oscillation frequency of the multivibrator is linearly related to the pressure applied to the thin film pressure sensor.

[0043] As shown in the attached figure Figure 11An exemplary female pelvic floor muscle pressure detection system according to an embodiment of the present invention is shown. The system includes at least one thin film pressure sensor 20 and at least one multivibrator 30. The thin film pressure sensor 20 and the multivibrator 30 can be disposed on a carrier 10, with the thin film pressure sensor 20 electrically connected to the multivibrator 30, and the thin film pressure sensor 20 forming a feedback resistor for the multivibrator 30. Preferably, the multivibrator 30 is configured so that its oscillation frequency corresponds to the pressure applied to the thin film pressure sensor 20. This allows a user or operator to simply detect (or obtain) the oscillation frequency of the multivibrator 30 to obtain the pressure value applied to the thin film pressure sensor 20 based on the corresponding relationship between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20. Therefore, the exemplary female pelvic floor muscle pressure detection system according to an embodiment of the present invention overcomes the drawback of existing methods of detecting the pressure applied to the thin film pressure sensor by detecting the resistance of the thin film pressure sensor. Preferably, the multivibrator 30 is configured so that its oscillation frequency changes monotonically with changes in the resistance (magnitude) of the thin film pressure sensor 20. More preferably, the multivibrator 30 is configured so that its oscillation frequency decreases monotonically with increasing resistance of the thin film pressure sensor 20, and the resistance of the thin film pressure sensor 20 decreases monotonically with increasing pressure. Accordingly, when the pressure applied to the thin film pressure sensor 20 is greater, the oscillation frequency of the multivibrator 30 detected by the exemplary female pelvic floor muscle pressure detection system according to an embodiment of the present invention is also greater.

[0044] Attached Figure 2A and Figure 4AThe multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is shown, wherein the multivibrator 30 includes a first resistive component 31, a second resistive component 32, an operational amplifier 33, and a capacitive component 34. One end of the first resistive component 31 is electrically connected to the second resistive component 32 and the non-inverting input terminal of the operational amplifier 33, respectively, and the other end is electrically connected to the second end 22 of the thin film pressure sensor 20 and the output terminal of the operational amplifier 33, respectively. One end of the second resistive component 32 is grounded, and the other end is electrically connected to the non-inverting input terminal of the operational amplifier 33, respectively. The inverting input terminal of the multivibrator 30 is electrically connected to the first resistive component 31. One end of the capacitive component 34 is grounded, and the other end is electrically connected to the inverting input terminal of the operational amplifier 33 and the first end 21 of the thin film pressure sensor 20. The output terminal of the operational amplifier 33 is electrically connected to the second end 22 of the thin film pressure sensor 20 and the first resistive component 31, respectively. The inverting input terminal of the operational amplifier 33 is electrically connected to the first end 21 of the thin film pressure sensor 20 and the capacitive component 34, respectively. The non-inverting input terminal of the operational amplifier 33 is electrically connected to the first resistive component 31 and the second resistive component 32, respectively. It can be understood that the first resistive component 31 and the second resistive component 32 of the exemplary multivibrator 30 of the female pelvic floor muscle pressure detection system according to the embodiment of the present invention are electrical components having a certain resistance and are composed of one or more components. The capacitive component 34 of the exemplary multivibrator 30 of the female pelvic floor muscle pressure detection system according to the embodiment of the present invention is an electrical component having a certain capacitance and is composed of one or more components. Accordingly, the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention has various implementations.

[0045] As shown in the attached figure Figures 2A to 3B As shown, when the first resistive component 31 and the second resistive component 32 of the multivibrator 30 are both single resistors, and the capacitive component 34 is a single capacitor, the multivibrator 30 is configured so that the oscillation frequency F of the multivibrator 30 and the resistance Rsensor of the thin film pressure sensor 20 satisfy the following formula:

[0046]

[0047] Where C is the capacitance of the capacitive component 34, R1 is the resistance of the first resistive component 31, and R2 is the resistance of the second resistive component 32. Accordingly, the resistance-oscillation frequency curve of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention and the resistance-pressure curve of the thin film pressure sensor 20 may overlap or approximately overlap. It is worth noting that the capacitance of the capacitive component 34 of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention ranges from 10pF to 330uF. Repeated testing and multiple experiments have revealed that when the capacitance of the capacitive component 34 is less than 10pF, the error caused by stray capacitance in the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is difficult to reduce to an ideal range. When the capacitance of the capacitive component 34 is greater than 330uF, the volume of the capacitive component 34 is too large to meet the requirements of the present invention for detecting female pelvic floor muscle pressure. Preferably, the capacitor of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is a COG or NPO ceramic capacitor to ensure the temperature stability of the female pelvic floor muscle pressure detection system of the present invention.

[0048] As shown in the attached figure Figure 3A and Figure 3B As shown, when the first resistive component 31 and the second resistive component 32 of the multivibrator 30 are both single resistors, and the capacitive component 34 is a single capacitor, according to the exemplary resistance-oscillation frequency variation curve of the multivibrator 30 and the resistance-pressure variation curve of the thin film pressure sensor 20 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention, through calculation and further linear fitting, a "linear relationship" between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 can be obtained:

[0049] Where N is the pressure applied to the thin film pressure sensor 20, F is the real-time detected oscillation frequency of the multivibrator 30, f is the oscillation frequency of the multivibrator 30 when the pressure applied to the thin film pressure sensor 20 is zero, and K is a constant. It will be appreciated that the constant K is related to the thin film pressure sensor 20. It will be appreciated that the "linear relationship" between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 can also be obtained using other linear fitting methods, such as second-order fitting or multi-order fitting.

[0050] It is worth noting that, as shown in the attached figure Figure 2BAs shown, when the first resistive component 31 and the second resistive component 32 of the multivibrator 30 are both single resistors, and the capacitive component 34 is a single capacitor, the "coincidence" between the resistance-oscillation frequency variation curve of the multivibrator 30 for detecting female pelvic floor muscle pressure according to the exemplary embodiment of the present invention and the resistance-pressure variation curve of the thin film pressure sensor 20 does not necessarily coincide completely, but rather coincides based on the fact that the oscillation frequency of the multivibrator 30 for detecting female pelvic floor muscle pressure according to the exemplary embodiment of the present invention decreases monotonically with the increase of the resistance of the thin film pressure sensor 20. The main reason is that the oscillation frequency change of the multivibrator 30 used to detect female pelvic floor muscle pressure according to the exemplary embodiment of the present invention is a simulation of the change in the resistance of the thin film pressure sensor 20 with pressure. The change in the oscillation frequency of the multivibrator 30 is difficult to be completely consistent with the change in the resistance of the thin film pressure sensor 20 with pressure. In particular, when the pressure on the thin film pressure sensor 20 is small, the resistance changes greatly with pressure, and when the pressure is large, the resistance changes less with pressure. As shown in the attached figure Figure 3B As shown, the "linear relationship" between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20, according to the exemplary embodiment of the present invention for detecting female pelvic floor muscle pressure, is a calculated linear relationship. However, even so, the configuration method of the multivibrator 30 of the present invention allows a user or operator to more accurately detect the female pelvic floor muscle pressure applied to the thin film pressure sensor 20 and significantly improve the upper and lower limits of the female pelvic floor muscle pressure that the thin film pressure sensor 20 can detect by combining the thin film pressure sensor 20 and the configured multivibrator 30. Optionally, the user can further improve the "linear relationship" between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 through linear fitting, such as first-order linear fitting or multi-order linear fitting, to achieve even higher accuracy in detecting female pelvic floor muscle pressure.

[0051] Accordingly, when used to detect female pelvic floor muscle pressure, the user or operator can set the exemplary thin film pressure sensor 20 for detecting female pelvic floor muscle pressure according to the embodiment of the present invention on an appropriate carrier 10, and then place the carrier 10 with the thin film pressure sensor 20 attached at an appropriate position in the female body, so that the female pelvic floor muscle pressure can act on the thin film pressure sensor 20 or be transmitted to the thin film pressure sensor 20. Generally, the carrier 10 with the thin film pressure sensor 20 attached is placed in the female pelvic cavity (or other position of the human body) so that the female pelvic floor muscle pressure acts on the thin film pressure sensor 20. Therefore, the carrier 10 with the thin film pressure sensor 20 attached is preferably set to a spherical body or a rod-shaped body that is convenient for bearing force. In this way, female pelvic floor muscle pressure can be detected. As shown in the accompanying drawings Figure 2A and Figure 4A As shown, to ensure smooth startup of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to an embodiment of the present invention, especially to ensure smooth oscillation even when the thin film pressure sensor 20 is not subjected to pressure, the exemplary female pelvic floor muscle pressure detection system according to an embodiment of the present invention further includes a startup resistor 90, wherein the startup resistor 90 is electrically connected to the multivibrator 30 in parallel with the thin film pressure sensor 20. The startup resistor 90 of the female pelvic floor muscle pressure detection system of the present invention increases the base frequency (or oscillation starting frequency) and the response time of the thin film pressure sensor 20 when the pressure value is small.

[0052] Accordingly, Where C is the capacitance of the capacitive component 34, R1 is the resistance of the first resistive component 31, R2 is the resistance of the second resistive component 32, Rsensor is the resistance of the thin film pressure sensor 20, and Rsp is the resistance of the startup resistor 90. It can be understood that the startup resistor 90 can also be regarded as a component or part of the multivibrator 30.

[0053] As shown in the attached figure Figure 4A and Figure 4B As shown, in order to make the resistance-oscillation frequency variation curve of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to the embodiment of the present invention more similar to the resistance-pressure value variation curve of the thin film pressure sensor 20 and to improve the linearity between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20, the structures of the first resistive component 31, the second resistive component 32 and the capacitive component 34 of the exemplary multivibrator 30 for detecting female pelvic floor muscle pressure according to the embodiment of the present invention can be further improved. The capacitive component 34 of the improved multivibrator 30 includes a first resistor 341, a second resistor 342 and a first capacitor 343. The first resistive component 31 includes at least one first adjustment resistor 311, and the second resistive component 32 includes at least one second adjustment resistor 321. The first resistor 341 and the first capacitor 343 of the capacitive component 34 are connected in series, and the first resistor 341, the first capacitor 343 and the second resistor 342 are connected in parallel. As shown in the accompanying drawings, Figure 4AAs shown, further, the multivibrator 30 further includes a second capacitor 344, the first resistive component 31 further includes at least one first adjustment capacitor 312, and the second resistive component 32 further includes at least one second adjustment capacitor 322, wherein the first resistor 341 and the first capacitor 343, the second resistor 342, and the second capacitor 344 are connected in parallel, the first adjustment resistor 311 and the first adjustment capacitor 312 are connected in parallel, and the second adjustment resistor 321 and the second adjustment capacitor 322 are connected in parallel.

[0054] Accordingly, Where C is the capacitance of the capacitive component 34, R1 is the resistance of the first resistive component 31, R2 is the resistance of the second resistive component 32, Rsensor is the resistance of the thin film pressure sensor 20, Rsp is the resistance of the start resistor 35, ZC1 is the capacitance impedance of the first adjustment capacitor 312, and ZC2 is the capacitance impedance of the second adjustment capacitor 322. Figure 4B As shown in FIG. 1 , the improved linearity between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 is better (first-order fitting), and the accuracy of the pressure detection result applied to the thin film pressure sensor 20 is higher. It is understood that the "linear relationship" between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 can also be obtained by other linear fitting methods, such as second-order fitting or multi-order fitting. As shown in FIG. Figures 2A to 3B As shown in FIG. 1 , when the oscillation frequency of the multivibrator 30 for detecting female pelvic floor muscle pressure according to an exemplary embodiment of the present invention is above 1000 Hz, the error between the response curve of the multivibrator 30 and the response curve of the thin film pressure sensor 20 increases significantly. Figure 4A and Figure 4B As shown, by introducing reactive components, such as the first adjustment capacitor 312 and the second adjustment capacitor 322, into the feedback network, the problem of increased error between the response curve of the multivibrator 30 and the response curve of the thin film pressure sensor 20 when the oscillation frequency of the multivibrator 30 is above 1000 Hz is partially overcome, thereby improving the linearity between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20. Furthermore, in an exemplary multivibrator 30 of the female pelvic floor muscle pressure detection system according to an embodiment of the present invention, when the resistance of the first resistive component 31 and the second resistive component 32 are 100-100 MΩ, the linearity between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 is improved. When the resistance of the first resistive component 31 and the second resistive component 32 are the same, the linearity between the oscillation frequency of the multivibrator 30 and the pressure applied to the thin film pressure sensor 20 is also improved.

As shown in the accompanying drawings Figure 2A and Figure 2B As shown, at low frequencies, the midpoint potential of the exemplary multivibrator 30 of the female pelvic floor muscle pressure detection system according to an embodiment of the present invention is determined by the resistance of the first potential resistor 81 and the resistance of the second resistive component 32. At high frequencies, the frequency error caused by the feedback current is large, which can be reduced by adding a filter capacitor and a buffer circuit.

[0056] Attached Figure 5A and Figure 6A FIG. 1 shows another exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention, wherein the multivibrator 30A includes a first resistive component 31, a second resistive component 32, a comparator 33A, and a capacitive component 34. One end of the first resistive component 31 is electrically connected to the second resistive component 32 and the non-inverting input end of the comparator 33A, respectively, and the other end is electrically connected to the second end 22 of the thin film pressure sensor 20 and the output end of the comparator 33A, respectively. One end of the second resistive component 32 is grounded, and the other end is electrically connected to the comparator 33A, respectively. The non-inverting input terminal of the comparator 33A is electrically connected to the first resistive component 31, one end of the capacitive component 34 is grounded, and the other end is electrically connected to the inverting input terminal of the comparator 33A and the first end 21 of the thin film pressure sensor 20, respectively. The output terminal of the comparator 33A is electrically connected to the second end 22 of the thin film pressure sensor 20 and the first resistive component 31, respectively. The inverting input terminal of the comparator 33A is electrically connected to the first end 21 of the thin film pressure sensor 20 and the capacitive component 34, respectively. The non-inverting input terminal of the comparator 33A is electrically connected to the first resistive component 31 and the second resistive component 32, respectively. It will be understood that the first resistive component 31 and the second resistive component 32 of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention are each an electrical component having a certain resistance, and are composed of one or more components; and the capacitive component 34 of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is an electrical component having a certain capacitance, and are composed of one or more components. Accordingly, the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention has various implementations.

[0057] As shown in the attached figure Figure 5A As shown, when the first resistive component 31 and the second resistive component 32 of the multivibrator 30A are both single resistors, and the capacitive component 34 is a single capacitor, the multivibrator 30A is configured so that the oscillation frequency F of the multivibrator 30A and the resistance Rsensor of the thin film pressure sensor 20 satisfy the following formula:

[0058]

[0059] Where C is the capacitance of the capacitive component 34, R1 is the resistance of the first resistive component 31, and R2 is the resistance of the second resistive component 32. Accordingly, the resistance-oscillation frequency variation curve of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention coincides or approximately coincides with the resistance-pressure variation curve of the thin film pressure sensor 20. It is worth noting that the capacitance of the capacitive component 34 of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is between 10pF and 330uF. Repeated testing and multiple experiments have revealed that when the capacitance of the capacitive component 34 is less than 10pF, the error caused by stray capacitance in the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is difficult to reduce to an ideal range. When the capacitance of the capacitive component 34 is greater than 330uF, the volume of the capacitive component 34 is too large to meet the requirements of the female pelvic floor muscle pressure detection system of the present invention. Preferably, the capacitor of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention is a COG or NPO ceramic capacitor to ensure the temperature stability of the female pelvic floor muscle pressure detection system of the present invention.

[0060] As shown in the attached figure Figure 5A As shown in FIG. 1 , when the first resistive component 31 and the second resistive component 32 of the multivibrator 30A are both single resistors, and the capacitive component 34 is a single capacitor, according to an exemplary resistance-oscillation frequency variation curve of the multivibrator 30A and an exemplary resistance-pressure variation curve of the thin film pressure sensor 20 of the female pelvic floor muscle pressure detection system according to an embodiment of the present invention, through calculation and further linear fitting, a “linear relationship” between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 can be obtained:

[0061] Where N is the pressure applied to the thin film pressure sensor 20, F is the real-time detected oscillation frequency of the multivibrator 30A, f is the oscillation frequency of the multivibrator 30A when the pressure applied to the thin film pressure sensor 20 is zero, and K is a constant. It will be understood that the constant K is related to the thin film pressure sensor 20. It will be understood that the "linear relationship" between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 can also be obtained using other linear fitting methods, such as second-order fitting or multi-order fitting.

[0062] It is worth noting that when the first resistive component 31 and the second resistive component 32 of the multivibrator 30A are both single resistors and the capacitive component 34 is a single capacitor, the "coincidence" between the resistance-oscillation frequency variation curve of the multivibrator 30A for detecting female pelvic floor muscle pressure according to the exemplary embodiment of the present invention and the resistance-pressure variation curve of the thin film pressure sensor 20 is not necessarily a complete coincidence, but is based on the coincidence that the oscillation frequency of the multivibrator 30A for detecting female pelvic floor muscle pressure according to the exemplary embodiment of the present invention monotonically decreases with the increase of the resistance of the thin film pressure sensor 20. The main reason is that the oscillation frequency change of the multivibrator 30A used to detect female pelvic floor muscle pressure according to the exemplary embodiment of the present invention is a simulation of the change in the resistance of the thin film pressure sensor 20 with pressure. The change in the oscillation frequency of the multivibrator 30A is difficult to be completely consistent with the change in the resistance of the thin film pressure sensor 20 with pressure. In particular, when the pressure on the thin film pressure sensor 20 is small, the resistance changes greatly with pressure, and when the pressure on the thin film pressure sensor 20 is large, the resistance changes less with pressure. As shown in the attached figure Figure 5B As shown, the "linear relationship" between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20, according to the exemplary embodiment of the present invention for detecting female pelvic floor muscle pressure, is a calculated linear relationship. However, even so, the configuration method of the multivibrator 30A of the present invention allows users or operators to more accurately detect female pelvic floor muscle pressure applied to the thin film pressure sensor 20 and significantly improve the upper and lower limits of the female pelvic floor muscle pressure that the thin film pressure sensor 20 can detect by combining the thin film pressure sensor 20 and the configured multivibrator 30A. Optionally, the user can further improve the "linear relationship" between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 through linear fitting, such as first-order linear fitting or multi-order linear fitting, to achieve even higher accuracy in detecting female pelvic floor muscle pressure.

[0063] As shown in the attached figure Figure 5BAs shown, accordingly, according to the resistance-pressure value variation curve of the thin film pressure sensor 20 of the female pelvic floor muscle pressure detection system of the present invention and the relationship between the oscillation frequency F of the multivibrator 30A and the resistance R of the thin film pressure sensor 20, a linear relationship between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 is obtained through calculation:

[0064] Where N is the pressure applied to the thin film pressure sensor 20, F is the oscillation frequency of the multivibrator detected in real time, f is the oscillation frequency of the multivibrator 30A when the pressure applied to the thin film pressure sensor 20 is zero, and K is a constant. It will be understood that the constant K is related to the thin film pressure sensor 20.

[0065] As shown in the attached figure Figure 6A and 6B As shown, in order to ensure the smooth start-up of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to an embodiment of the present invention, especially when the thin film pressure sensor 20 is not under pressure, the female pelvic floor muscle pressure detection system of the present invention further includes a starting resistor 90, wherein the starting resistor 90 and the thin film pressure sensor 20 are electrically connected to the multivibrator 30A in parallel.

[0066] Accordingly, Wherein, C is the capacitance of the capacitive component 34 , R1 is the resistance of the first resistive component 31 , R2 is the resistance of the second resistive component 32 , Rsensor is the resistance of the thin film pressure sensor 20 , and Rsp is the resistance of the startup resistor 90 .

[0067] As shown in the attached figure Figure 6A and Figure 6B As shown, in order to make the resistance-oscillation frequency variation curve of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to the embodiment of the present invention more similar to the resistance-pressure value variation curve of the thin film pressure sensor 20, the structures of the first resistive component 31, the second resistive component 32 and the capacitive component 34 of the exemplary multivibrator 30A for detecting female pelvic floor muscle pressure according to the embodiment of the present invention can be further improved, wherein the capacitive component 34 of the improved multivibrator 30A includes a first resistor 341, a second resistor 342 and a first capacitor 343, the first resistive component 31 includes at least one first adjustment resistor 311, the second resistive component 32 includes at least one second adjustment resistor 321, wherein the first resistor 341 and the first capacitor 343 of the capacitive component 34 are connected in series, and the first resistor 341 and the first capacitor 343 and the second resistor 342 are connected in parallel. As shown in the accompanying drawings Figure 6AAs shown, further, the multivibrator 30A further includes a second capacitor 344, the first resistive component 31 further includes at least one first adjustment capacitor 312, and the second resistive component 32 further includes at least one second adjustment capacitor 322, wherein the first resistor 341 and the first capacitor 343, the second resistor 342, and the second capacitor 344 are connected in parallel, the first adjustment resistor 311 and the first adjustment capacitor 312 are connected in parallel, and the second adjustment resistor 321 and the second adjustment capacitor 322 are connected in parallel.

[0068] Accordingly, Where C is the capacitance of the capacitive component 34, R1 is the resistance of the first resistive component 31, R2 is the resistance of the second resistive component 32, Rsensor is the resistance of the thin film pressure sensor 20, Rsp is the resistance of the start resistor 90, ZC1 is the capacitance impedance of the first adjustment capacitor 312, and ZC2 is the capacitance impedance of the second adjustment capacitor 322. Figure 6B As shown in FIG. 1 , the improved linearity between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 is better (first-order fitting), and the accuracy of the pressure detection result applied to the thin film pressure sensor 20 is higher. It is understood that the "linear relationship" between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20 can also be obtained by other linear fitting methods, such as second-order fitting or multi-order fitting. As shown in FIG. Figure 5A and Figure 5B As shown in FIG. 1 , when the oscillation frequency of the multivibrator 30A is above 1000 Hz, the error between the response curve of the multivibrator 30A and the response curve of the thin film pressure sensor 20 increases significantly. Figure 6A and Figure 6B As shown, by introducing reactive devices, such as the first adjustment capacitor 312 and the second adjustment capacitor 322, into the feedback network, the feedback coefficient of the multivibrator 30A changes with the change of the oscillation frequency, so as to reduce the error between the response change curve of the multivibrator 30A and the response change curve of the thin film pressure sensor 20 when the oscillation frequency of the multivibrator 30A is above 1000 Hz, and to improve the linearity between the oscillation frequency of the multivibrator 30A and the pressure applied to the thin film pressure sensor 20.

As shown in the accompanying drawings Figure 2A and Figure 2B As shown, at low frequencies, the midpoint potential of the exemplary multivibrator 30 of the female pelvic floor muscle pressure detection system according to an embodiment of the present invention is determined by the resistance of the first potential resistor 81 and the resistance of the second resistive component 32. At high frequencies, the frequency error caused by the feedback current is large, which can be reduced by adding a filter capacitor and a buffer circuit.

Figure 7 and Figure 8 As shown, compared with the multivibrator 30 and the multivibrator 30A, the multivibrator 30B has a simpler structure and lower cost, but the linearity between the oscillation frequency of the multivibrator 30B and the pressure applied to the thin film pressure sensor 20 is slightly poor.
