Description

Technical Field

[0001] The present invention belongs to the field of medical detection technology, and in particular relates to an airbag-type pelvic floor diagnosis and treatment device with multimodal data fusion. Background Art

[0002] Pelvic floor dysfunction (PFD) encompasses a range of conditions related to pelvic floor structure and function, including stress urinary incontinence, sexual dysfunction, pelvic organ prolapse, vaginal laxity, and fecal incontinence. These conditions severely impact patients' quality of life. Due to the complex structure of the female pelvic floor system and the multiple sources of pelvic floor disorders, diagnosis and treatment in this area present significant challenges.

[0003] Existing pelvic floor rehabilitation and treatment equipment often only provides a single, isolated data dimension when collecting information, with low intelligence levels. For example, it relies solely on single technologies such as ultrasound or electromyography for assessment. This limitation leads to low diagnostic accuracy for pelvic floor disorders, poor personalized treatment, and high uncertainty in efficacy. Therefore, developing an intelligent pelvic floor precision diagnosis and treatment system that can integrate multimodal information has extremely important clinical significance and social value for improving diagnostic accuracy, developing personalized treatment plans, and enhancing treatment outcomes.

[0004] In recent years, with the continuous advancement of technology, the application of multimodal data fusion technology in the medical field has gradually increased. Chinese patent application publication number CN115530881A discloses a multimodal data fusion method and device for holistic pelvic floor function assessment. This method uses an optical imaging module to obtain basic pelvic floor information, an ultrasound module to obtain ultrasound-based assessment information on pelvic tissue, nerves, blood vessels, and musculoskeletal function, and a muscle strength and electromyography detection module to obtain pelvic floor function assessment information based on muscle strength and electromyography data. Finally, based on the multi-module signal fusion of the optical imaging module, ultrasound module, and muscle strength and electromyography detection module, a comprehensive pelvic floor function assessment is obtained. However, although this method achieves multimodal data fusion, it still has some shortcomings: First, this method lacks the assessment of the vaginal morphology of the pelvic floor. Vaginal morphology is one of the important indicators for evaluating pelvic floor function, and its changes are closely related to the occurrence and development of pelvic floor diseases. Therefore, the lack of assessment of vaginal morphology may affect the accuracy of the overall assessment; Second, this method fails to use mechanical data to further analyze the softness and hardness of the pelvic floor tissue. Through the analysis of mechanical data, we can have a deeper understanding of the physiological and pathological changes of the pelvic floor tissue; Third, the finger cuff probe used in this method has the problem of poor compatibility. Due to differences in body shape and physiological structure among different patients, the finger cuff probe may not be able to adapt to the needs of all patients, thereby affecting the accuracy and comfort of the assessment. At the same time, the finger cuff probe is also susceptible to interference from the test environment. Environmental factors such as temperature and humidity may affect the performance and stability of the probe, thereby affecting the reliability of the assessment results.

[0005] To address these issues, research needs to further explore more comprehensive pelvic floor assessment methods and techniques to improve the accuracy and effectiveness of pelvic floor disease diagnosis and treatment. At the same time, it is also necessary to pay attention to the comfort and needs of patients and design more humane and compatible equipment. Summary of the Invention

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0039] The inventive concept of the present invention is: in response to the problems of insufficient data collection dimensions, poor compatibility, and susceptibility to interference from the test environment in the prior art pelvic floor diagnosis and treatment equipment, the embodiment of the present invention provides an airbag-type pelvic floor diagnosis and treatment equipment with multimodal data fusion, which integrates the multimodal data collected by the pelvic floor pressure detection module, the pelvic floor electromyography acquisition and electromyography stimulation module, the vaginal morphology detection module and the airbag pressure assessment module to perform pelvic floor condition assessment, thereby achieving efficient and accurate pelvic floor measurement.

[0040] Figure 1 FIG. 1 is a schematic diagram of the structure of the multimodal probe external airbag 1 of the airbag type pelvic floor diagnosis and treatment device with multimodal data fusion provided by an embodiment of the present invention. Figure 1 As shown, the embodiment provides an external airbag structure, including: an external airbag 1, a pressure sensor array 11, an electromyographic electrode group 12, a direction sensor array 13, and an air pressure sensor 14.

[0041] Figure 2 This is a schematic diagram of the structure of the internal rigid support member 2 of the multimodal probe of the multimodal data fusion airbag-type pelvic floor diagnosis and treatment device provided by an embodiment of the present invention. The internal rigid support member 2 and the external airbag 1 are fixed together using glue to form the multimodal probe. In this embodiment, the internal rigid support member 2 is an internal rigid resin support member, and the glue is silicone glue, specifically silicone glue GT-701.

[0042] In the embodiment, the pressure sensor array 11 is an ionized pressure sensor, whose upper and lower electrode materials are gold deposited on a flexible polyimide film, the thickness of the deposited metal layer is 20μm, and the ion gel layer is made of a polyvinyl alcohol solution and a phosphoric acid solution in a ratio of 9:1, and the thickness of the ion gel layer is 160μm. The ionized pressure sensor is a new pressure sensing technology based on the principle of the electric double layer (EDL) interface. This principle causes the contact area between the electrode and the ionic material to change when the sensor is subjected to pressure, thereby changing the interface capacitance. This capacitance change can be measured and converted into a pressure signal, realizing the perception and measurement of pressure. For the same ionic material, the interface capacitance is mainly positively correlated with the contact area between the electrode and the ionic material. This makes the ionized pressure sensor highly sensitive, has a wide measurement range, is highly applicable, can quickly sense pressure changes and output corresponding signals, can monitor pressure changes in real time, and can maintain measurement stability.

[0043] In this embodiment, a pressure sensor array 11 is attached to the rigid protrusion at the top of the internal rigid support member 2. This combination of pressure sensor array 11 can not only capture information about the strength of biological tissue, but also its softness and hardness. The strain on the rigid protrusion can be used to calculate the elastic modulus of the vaginal wall using the formula E = σ / ε, where E is the elastic modulus, σ is the stress, and ε is the strain. The elastic modulus reflects the elasticity and toughness of the vagina, helping to understand vaginal health and potential disease risks.

[0044] In the embodiment, the direction sensor array 13 is of model MPU9250, which has a built-in three-axis accelerometer, a three-axis angular velocity meter and a magnetometer for acquiring vaginal morphology data.

[0045] like Figure 3 The figure shows a schematic diagram of the distribution of the multimodal probe pressure sensor array 11 and the direction sensor array 13 of the airbag pelvic floor diagnosis and treatment device with multimodal data fusion according to the clock direction provided by the embodiment of the present invention. In the embodiment, the pressure sensor array 11 and the direction sensor array 13 are arranged in accordance with Figure 3The 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock directions are arranged to obtain comprehensive data from all directions.

[0046] In the embodiment, the electrodes in the electromyographic electrode group 12 are circular or elliptical, and serpentine routing is used between the electrodes of the electrode array to ensure ductility. The circular ring is 270°, and the number of flexible electrodes is set to 18 according to muscle distribution to fully obtain electromyographic data.

[0047] In the embodiment, the material of the electrode sheets in the myoelectric electrode group 12 is gold.

[0048] In the embodiment, the air pressure sensor 14 is of model XGZP6827D, which collects air pressure signals to observe the air pressure changes of the airbag and obtain the contraction and relaxation activity information of the pelvic floor muscles.

[0049] Figure 4 This is a planar distribution diagram of a multimodal probe electromyographic electrode group 12 of a multimodal data fusion airbag pelvic floor diagnosis and treatment device provided by an embodiment of the present invention. The electrodes in the electromyographic electrode group 12 are arranged according to Figure 4 Distributed on the multimodal probe, the D1-D4 electrodes are distributed on the iliococcygeus muscle, the M1-M4 electrodes are distributed on the pubococcygeus muscle, the M5, M6 and S1-S4 electrodes are distributed on the urethral sphincter, puborectalis muscle and external anal sphincter, and the S5-S8 electrodes are distributed on the vaginal sphincter.

[0050] In the embodiment, considering that each patient may have different physiological structures when performing pelvic floor diagnosis and treatment for the patient, the airbag pelvic floor diagnosis and treatment device provided in the embodiment of the present invention has a gas injection position in the overall design. The doctor can slowly inject gas into the inflatable probe to expand the probe and fit it against the skin, ensuring that the electrodes on the surface of the probe are in full contact with the skin.

[0051] Figure 5 This is a schematic diagram of the detection principle of the multimodal probe vaginal morphology detection module of the multimodal data fusion airbag pelvic floor diagnosis and treatment device provided by the embodiment of the present invention. Figure 5 The changes in angle α shown (eg, angle α1 to angle α2) reveal changes in vaginal morphology.

[0052] In the embodiment, when a multi-module fusion probe is used for data acquisition, the patient is in static, Valsalva dynamic or Kegal dynamic state.

[0053] In an embodiment, a computer device includes a memory, a processor, and a computer program stored and executed on the processor, which mainly includes three parts: data preprocessing, feature extraction, and data fusion. The data preprocessing part aims to clean and standardize data from different sources to ensure data quality and prepare for subsequent analysis. It mainly includes: data denoising, applying filtering algorithms to remove noise in sensor data; data normalization, normalizing all data to a uniform range for easy processing; and data synchronization, ensuring that data from different sensors are aligned in time. The feature extraction part is the process of extracting useful information from the raw data. This information is critical for subsequent evaluation. It includes extracting features such as mean potential and frequency distribution from electromyographic data; extracting indicators such as maximum muscle force and average muscle force from muscle force data; extracting morphological features from vaginal morphology data; and extracting peak pressure and average pressure from airbag pressure data. The data fusion part combines the features extracted from each modality. It can be achieved through different strategies, such as early fusion, late fusion, or model-level fusion. One method is to use a machine learning model (such as a decision tree, support vector machine, or deep learning model) to integrate these features and perform learning and classification. Finally, based on the fused data, the computer program will apply a pre-trained model to perform a comprehensive assessment, which can determine muscle function recovery or evaluate treatment effectiveness. The aforementioned computer device, including a memory device, a processor, and a computer program stored and running on the processor, can collect and process multimodal pelvic floor data, achieving the purpose of diagnosing and treating pelvic floor disorders.

[0054] In summary, a multimodal data fusion airbag pelvic floor diagnosis and treatment device introduces an internal hard support 2 and an external airbag 1 to form a multimodal probe. Combined with the pressure sensor array 11, electromyographic electrode group 12, direction sensor array 13 and air pressure sensor 14 provided on the external airbag 1, it can evaluate the mechanical properties and strength level of the pelvic floor muscles, monitor and analyze the electrical activity of the pelvic floor muscles, evaluate the pelvic floor coordination and strength status, judge the function and activity status of the pelvic floor muscles, and obtain information on the contraction and relaxation activities of the pelvic floor muscles. In addition, the advantage of the combination of the internal hard support 2 and the external airbag 1 is that it can maintain the uniformity of the test standards, solve the problems of poor compatibility of the finger cuff method and susceptibility to interference from the test environment, make the test standards unified, and can perform quantitative indicator confirmation, which can meet the user's usage needs.

It should be understood that the above is only the most preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, supplements and equivalent substitutions made within the scope of the principles of the present invention should be included in the scope of protection of the present invention.
