Description

Technical Field

[0001] This invention relates to the field of pelvic floor muscle testing technology, and more specifically, to a digital pelvic floor muscle strength testing device. Background Technology

[0002] Pelvic floor dysfunction (PFD) is a group of conditions that affect women's quality of life, including urinary incontinence, pelvic organ prolapse, female sexual dysfunction, and fecal incontinence. Prevention is the true "root cause treatment" for PFD. Domestic and international research data confirm that pregnancy and childbirth are the leading risk factor for PFD. Timely and effective repair during this period of damage to the pelvic floor support structures can reduce the incidence of PFD and save on medical treatment costs. Postpartum pelvic floor rehabilitation in China has been developing for several years and is gradually becoming a trend in routine postpartum screening.

[0003] However, most pelvic floor muscle testing devices currently used in clinical practice are indirect testing tools, such as vaginal pressure probe tests and pelvic floor muscle electromyography (EMG) tests. Current testing methods cannot eliminate the interference of other muscles, such as abdominal muscles, gluteal muscles, and adductor muscles, on the pressure exerted by the pelvic floor muscles during contraction. Furthermore, since the data is collected by machines inside the vagina, clinicians cannot extract the pure pelvic floor muscle contraction values ​​from the data. In addition, the current clinical "gold standard" for pelvic floor muscle testing—digital vaginal examination—is highly susceptible to subjective influence and yields crude results. Digital vaginal examination uses the Modified Oxford Scale (MOS), with results ranging from 0 to 5, and does not include testing of pelvic floor muscle tone. Incomplete pelvic floor muscle testing will affect the clinical assessment process and treatment outcomes.

[0004] Therefore, there is an urgent need for a digital pelvic floor muscle strength testing device. Summary of the Invention

[0005] The purpose of this invention is to provide a digital pelvic floor muscle strength testing device to solve the problems in the prior art, which is more clinically operable and can realize the digital detection of pelvic floor muscle strength level. The test results can then assist in the clinical diagnosis and treatment process of pelvic floor dysfunction, forming a more rigorous and scientific diagnostic and treatment standard.

[0006] The present invention provides a digital pelvic floor muscle strength detection device, comprising: a detection glove, a detection base provided at the fingertips of the detection glove, detection contacts provided on the detection base, a pelvic floor muscle strength detection component disposed inside the detection base, and a pressure display module connected to the pelvic floor muscle strength detection component.

[0009] In the digital pelvic floor muscle strength testing device described above, preferably, the testing base is located at the fingertip or index finger position of the testing glove.

[0010] In the digital pelvic floor muscle strength detection device described above, preferably, the detection contacts include a muscle strength detection point located at the middle position of the detection base and a plurality of reference detection points spaced apart at the edge positions of the detection base, wherein the height of each reference detection point is the same and the height of the muscle strength detection point is greater than the height of the reference detection points.

[0011] In the digital pelvic floor muscle strength detection device described above, preferably, the pelvic floor muscle strength detection component includes a pressure sensor detection structure.

[0012] In the digital pelvic floor muscle strength detection device described above, preferably, the pressure sensor detection structure includes a detection point pressure sensor disposed at the muscle strength detection point and a reference point pressure sensor disposed at each of the reference detection points.

[0013] In the digital pelvic floor muscle strength detection device described above, preferably, both the detection point pressure sensor and each of the reference point pressure sensors include a thin-film pressure sensor.

[0014] In the digital pelvic floor muscle strength detection device described above, preferably, the pressure display module includes a wrist-worn structure or an external display device.

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0030] like Figures 1-6 As shown, the digital pelvic floor muscle strength detection device provided in this embodiment includes: a detection glove 3, a detection base 1 provided at the fingertips of the detection glove 3, a detection contact 2 provided on the detection base 1, a pelvic floor muscle strength detection component provided inside the detection base 1, and a pressure display module 4 connected to the pelvic floor muscle strength detection component.

[0031] The detection base 1 and the detection glove 3 are an integrated mechanism. In specific implementation, structural components of different materials can be fixed or glued together.

[0032] Furthermore, the pelvic floor muscle strength detection component is connected to the pressure display module 4 via a tube 301, and the tube 301 and the detection glove 3 are an integral structure. In one embodiment of the present invention, the tube 301 is made of a material with high hardness but certain deformability (nickel-titanium alloy, titanium alloy, cobalt-chromium alloy, platinum-chromium), which can move with slight movements of the fingers and palm without affecting the pneumatic pressure value. The diameter of the tube 301 is 1mm-2mm. It should be noted that the present invention does not specifically limit the material, diameter, length, etc. of the tube 301. In one embodiment of the present invention, both the detection glove 3 and the tube 301 are disposable medical consumables. In other embodiments of the present invention, they can also be reused, but corresponding material modifications are required to meet sterilization requirements.

[0033] Furthermore, the tubing 301 is quickly connected to the pressure display module 4 via a connection interface. In one embodiment of the invention, the pressure display module 4 includes a wrist-worn structure that can display the precise value of the current muscle strength. In another embodiment of the invention, the pressure display module 4 includes an external display device, such as a large display screen. In specific implementations, the external display device can be connected to the pelvic floor muscle strength detection component via Bluetooth or a wired connection, thereby providing more comprehensive pressure information.

[0034] Furthermore, the detection base 1 is located at the fingertip or index fingertip of the detection glove 3.

[0035] Furthermore, the detection contact 2 includes a muscle strength detection point located at the center of the detection base 1 and multiple reference detection points spaced apart at the edges of the detection base 1. All reference detection points have the same height, while the height of the muscle strength detection point is greater than that of the reference detection points. A preset height difference exists between the muscle strength detection point and the reference detection points, which facilitates the accurate detection of muscle strength values ​​through calibration of the reference pressure value. The muscle strength detection point and the reference detection points work together to detect muscle strength at various levels (e.g., level 0-level 5). The reference detection points can be arranged in a ring or have a multi-point contact structure. In one embodiment of the invention, the number of reference detection points can be three. It should be noted that the invention does not specifically limit the number or distribution of the reference detection points. In one embodiment of the invention, both the muscle strength detection point and each of the reference detection points are silicone contacts.

[0036] During operation, the detection base 1 is fixed on the detection glove 3. The pelvic floor muscle strength and pressure are detected through the detection base 1 and the detection contact 2. The pressure value data of the muscle strength is displayed through the pressure display module 4, realizing the rapid and accurate detection of pelvic floor muscle function. It can accurately detect muscle strength values, which is convenient for more accurate diagnosis of diseases and has good application prospects. The detection glove 3 can improve the operability of the device.

[0037] Furthermore, in this invention, the pelvic floor muscle strength detection component includes a pressure sensor detection structure.

[0038] Specifically, the pressure sensor detection structure includes a detection point pressure sensor 6002 disposed at the muscle strength detection point and a reference point pressure sensor 6003 disposed at each of the reference detection points.

[0039] In one embodiment of the present invention, both the detection point pressure sensor 6002 and each of the reference point pressure sensors 6003 include a thin-film pressure sensor 6. The thin-film pressure sensor 6 has high sensitivity, accurately sensing minute pressure changes and converting them into measurable electrical signals. It can easily adapt to various complex structures and responds sensitively to pressure changes. It is thin and compact: the thin-film pressure sensor 6 is thin, small in size, and lightweight, facilitating installation and integration into various systems without significantly affecting the structure and performance of the detection base, making it suitable for applications with stringent space requirements. Furthermore, the thin-film pressure sensor 6 has a fast response speed, quickly responding to pressure changes and enabling real-time monitoring of dynamic pressure changes, meeting the needs of high-speed measurement and control. The thin-film pressure sensor 6 also has good flexibility: it can conform to curved or irregularly shaped object surfaces for pressure measurement, expanding its application range. In a specific implementation, the flexible connecting wires of the thin-film pressure sensor 6 are integrated with the detection glove 3, embedded in the detection glove 3 and connected to the pressure display module 4.

[0040] In one embodiment of the present invention, the entire detection base 1 is installed on the fingertip of the detection glove 3. The location of each muscle is detected by the tactile sensation of the fingertip, and then the pressure sensor detection structure at the fingertip is used for detection (i.e., fingertip muscle strength detection method). In another embodiment of the present invention, the detection base 1 is installed on the fingertip 7 of the detection glove 3. The location of each muscle is detected by the tactile sensation of the fingertip, and then the pressure sensor detection structure at the fingertip is used for detection (finger muscle strength detection method). When using the finger muscle strength detection method, generally only one finger is used for detection. Therefore, the present invention provides pressure sensor detection structures at various positions of the finger to improve the accuracy and efficiency of detection.

[0041] In one embodiment of the present invention, the pelvic floor muscles are divided into 8 points that need to be detected. These points cover common points for pelvic floor muscle detection and rehabilitation. In a specific implementation, one point can be selected, and the pressure display module 4 acquires multi-directional pressure data from the thin-film pressure sensor 6 in real time. The detection of each point is further divided into 6 different levels of force from 0 to 5. Through a series of calculations and analyses, the detected force value, force level, force fluctuation curve, etc. are presented on the pressure display module 4.

[0042] Furthermore, in one embodiment of the present invention, the method for analyzing the pressure data of the detection contact 2 by the pressure sensor detection structure includes: a surrounding pressure balance calculation method and a pressure level analysis method. Specifically, the surrounding pressure balance algorithm analyzes the data of the area surrounding the detection contact 2 when pressing, that is, it analyzes the pressure value of the pressure sensor 6002 at the detection point above. If the surrounding pressure values ​​are within a reasonable range at the same time point and the fluctuations of the pressure points around them are not large, then the current state is considered to be in a relatively balanced state. The center pressure data of the muscle force detection point obtained in this state is more accurate and reliable. In a specific implementation, real-time pressure data is obtained through serial communication, and the pressure distribution and dynamic curve of the pressure are displayed in real time. The pressure balance is plotted in real time according to the calculation of the balance algorithm. The balance algorithm is used for detection, and at least three points are used for detection on a plane. The algorithm matches the three points with the center pressing point. Only when the force of the three points is less than that of the center pressing point and the pressure values ​​of the three points are similar will the current state be confirmed as the correct pressing posture.

[0043] The pressure rating analysis method analyzes and evaluates data based on the central pressure at the muscle strength testing point. When users apply the same force to the pelvic floor muscles, different muscle stiffness will result in different pressure ratings. This rating can intuitively reflect the muscle strength at the corresponding location in the pelvic floor muscles. Figure 7 As shown.

[0044] The digital pelvic floor muscle strength testing device provided in this invention has a simple structure, is clinically portable, and can directly test the pelvic floor muscles. It simulates the "gold standard" intravaginal digital examination method to directly test the corresponding pelvic floor muscle tension and strength values. It can accurately detect the force value of each muscle and is not affected by subjective human factors. At the same time, it realizes the digitization of the test results, and more accurately realizes the detection of pelvic floor muscle strength.
