Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a rheumatology and immunology device for detecting ankylosing spondylitis. Background Technology

[0002] Ankylosing spondylitis is a common chronic inflammatory disease in rheumatology and immunology, primarily affecting the spine, sacroiliac joints, and peripheral joints. Disease progression can lead to joint ankylosis and spinal deformities, severely impacting patients' quality of life. Early diagnosis and dynamic monitoring of this disease rely on accurate measurement of key postural parameters such as spinal curvature and joint range of motion. Furthermore, ensuring patient posture stability during testing is crucial to avoid assessment errors caused by postural deviations. Traditional methods primarily depend on manual examination by physicians and imaging assessments. These methods have inherent limitations in terms of standardization, quantification, and efficiency, making it difficult to meet the demands of modern precision medicine for data comparability and long-term tracking.

[0003] Currently, the main methods for detecting ankylosing spondylitis fall into two categories: one is traditional manual detection, where medical staff visually observe the patient's posture and use simple tools such as rulers and protractors to measure key dimensions, relying on the operator's professional experience to determine whether the posture is standard and the severity of the condition; the other is simple mechanical detection devices, which, although equipped with basic ranging or positioning components, lack a systematic posture fixation mechanism, relying solely on the patient to maintain the posture, and have a simple adjustment structure that is difficult to adapt to patients of different heights and waist circumferences. Furthermore, some existing devices lack intelligent calibration functions and cannot automatically determine whether the posture is compliant, requiring repeated manual adjustments. A few devices with data acquisition functions lack quantitative analysis models, only outputting raw data and unable to directly generate disease assessment results. The operation process is cumbersome, requiring a high level of professional expertise from medical staff. Additionally, these devices generally lack targeted safety protection designs, posing a risk of accidents due to pain or imbalance during the detection process, and their high maintenance costs make them difficult to promote in primary healthcare institutions.

[0004] In summary, the existing technology still has the following limitations: (1) strong subjectivity and poor repeatability: manual measurement results are greatly affected by the operator, and the comparability of different measurement data of the same patient is low; (2) lack of standardization: patients' postures are not uniform, which can easily introduce compensatory movement errors and affect the authenticity of the measurement; (3) insufficient efficiency and safety: the examination process is time-consuming and there is a risk of falling for patients with limited mobility. At the same time, it is impossible to achieve automatic data collection and intelligent analysis.

[0005] Therefore, the present invention aims to provide a rheumatology and immunology detection device for ankylosing spondylitis to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a detection device for ankylosing spondylitis in the field of rheumatology and immunology. This invention integrates a body protection mechanism and joint and lumbar support mechanisms, thereby constructing a standardized detection platform. By standardizing the patient's testing posture, it eliminates the subjective errors caused by posture differences in traditional manual measurement from the source. Combined with an intelligent detection system, it realizes a fully automated closed loop from automatic posture recognition, voice guidance, precise laser measurement to intelligent analysis. The device as a whole significantly improves the objectivity, repeatability, and comparability of measurement data, providing reliable and consistent quantitative evidence for the assessment of ankylosing spondylitis, the tracking of treatment efficacy, and clinical research, and significantly improves the safety and efficiency of detection.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a detection device for ankylosing spondylitis in the field of rheumatology and immunology, comprising a base plate, a side plate on the base plate, a sliding mechanism on the side plate, a sliding frame on the sliding mechanism, the sliding mechanism being used to adjust the relative position of the sliding frame and the side plate, a binocular laser rangefinder on the sliding frame, a body protection mechanism on the base plate for providing protection to the patient during the detection process, a joint assist mechanism on the base plate for assisting the patient's knee joint in maintaining a straight position, and a lumbar assist mechanism on the base plate for guiding the patient's lumbar region to remain stable against the base plate.

[0008] By adopting the above technical solution and using a sliding mechanism to adjust the position of the sliding frame, the binocular laser rangefinder can be moved flexibly to meet the testing needs of patients of different heights and body types, thus expanding the applicability of the device. At the same time, the body protection mechanism provides safety protection for patients during testing, avoiding bumps and injuries caused by posture adjustments or accidents. The joint assist mechanism ensures that the patient's knee joint remains straight, and the waist assist mechanism guides the waist to be close to the base plate, fixing the patient's posture from two key points to avoid testing errors caused by unstable posture and ensure the accuracy of the test data. The various mechanisms work together to form a complete testing process of flexible adjustment, stable posture, and safety protection, improving the standardization and reliability of the testing process.

[0009] The present invention is further configured such that: the sliding mechanism includes a connecting rod and a sliding ball, the side plate is provided with a sliding groove, the two ends of the connecting rod are respectively connected to the sliding frame and the sliding ball, and the sliding ball is located in the sliding groove and moves along the direction of the sliding groove.

[0010] By adopting the above technical solution, the cooperation between the sliding ball and the sliding groove reduces the frictional resistance of the movement compared with the traditional sliding structure with a hard connection between the slide rail and the slider. This makes the movement of the sliding frame smoother and more flexible, and facilitates the quick adjustment of the detection position of the binocular laser rangefinder. At the same time, the point contact cooperation between the sliding ball and the sliding groove reduces structural wear and extends the service life of the device. In addition, the structure is simple and compact, easy to maintain, and can quickly troubleshoot sliding faults.

[0011] The present invention is further configured such that: the body protection mechanism includes a telescopic rod, a U-shaped frame, a limiting block and an elastic rope; the fixed end of the telescopic rod is hinged to the base plate, the telescopic end is connected to the U-shaped frame, one end of the elastic rope is connected to the base plate, and the other end passes through the U-shaped frame and is connected to the limiting block.

[0012] By adopting the above technical solution, the telescopic rod can be flexibly adjusted in length and angle to adapt to the protection needs of different parts of the patient's body. The U-shaped frame provides stable support for the elastic rope, avoiding direct contact between the rope and the patient and causing local pressure. The elastic rope has good elasticity, which can not only play a protective and limiting role, but also will not affect the patient's breathing or blood circulation due to excessive tightness, thus improving the comfort of the examination. The limiting block can adjust the tightness of the elastic rope according to the patient's body shape, ensuring the protective effect while taking into account individual differences.

[0013] The present invention is further configured such that: the joint assist mechanism includes a joint strap, a movable buckle, and an adjustment mechanism; the base plate is provided with a joint assist groove, the adjustment mechanism is located in the joint assist groove, the joint strap is connected to the adjustment mechanism, the adjustment mechanism is used to adjust the position between the joint strap and the base plate, and the movable buckle is located on the joint strap to adjust the tightness of the joint strap.

[0014] By adopting the above technical solution, the adjustment mechanism can move the joint strap within the joint auxiliary groove to adapt to the different knee joint positions of different patients, ensuring that the strap can accurately fix the knee joint. The movable buckle can quickly adjust the tightness of the joint strap, ensuring that the knee joint remains in a straight position while avoiding joint discomfort or poor blood circulation caused by excessive tightness. This mechanism can effectively restrict the movement of the knee joint, prevent the patient's posture from shifting due to unconscious movements during the test, ensure the accuracy of knee joint-related parameters collected by the binocular laser rangefinder, provide reliable data support for condition assessment, and is simple to operate. Patients can cooperate to complete the strap fixation themselves, improving the efficiency of the test.

[0015] The present invention is further configured such that: the adjustment mechanism includes a fixed rod and a sliding block, the two ends of the fixed rod are connected to the opposite side walls of the joint auxiliary groove, the sliding block is sleeved on the fixed rod and moves along the direction of the fixed rod, and the joint strap is connected to the sliding block.

[0016] By adopting the above technical solution, the fixed rod provides a stable moving track for the sliding block, ensuring that the sliding block does not deviate during movement, thereby ensuring that the position adjustment of the joint strap is precise and controllable. The sleeve structure between the sliding block and the fixed rod is simple, with low movement resistance and smooth adjustment process, which can quickly adjust the joint strap to the target position. This structure has strong load-bearing capacity and can stably support the tension of the joint strap, avoiding deformation or loosening after long-term use, extending the service life of the mechanism, and the manufacturing process is simple, reducing production costs and facilitating mass production.

[0017] The present invention is further configured such that: the waist support mechanism includes a waist strap, a movable buckle, and an adjustment mechanism; the base plate is provided with a waist support groove, the adjustment mechanism is located in the waist support groove, the waist strap is connected to the adjustment mechanism, the adjustment mechanism is used to adjust the position between the waist strap and the base plate, and the movable buckle is located on the waist strap to adjust the tightness of the waist strap.

[0018] By adopting the above technical solution, the adjustment mechanism moves the lumbar strap within the lumbar auxiliary groove, which can adapt to the needs of patients with different lumbar circumferences. It ensures that the strap fits snugly against the waist, and the adjustable buckle adjusts the tightness of the strap. This ensures that the patient's waist is close to the base plate, avoiding postural instability caused by waist swaying during the test, while also preventing excessive tightness from compressing the lumbar muscles or spine, thus improving patient comfort. This mechanism can effectively fix the lumbar posture, ensuring the stability of key parts such as the lumbar spine and hip joints. It provides accurate conditions for the laser rangefinder to collect parameters such as spinal curvature and waist-to-base fit, ensuring the accuracy of the condition assessment.

[0019] The present invention is further configured such that: the adjustment mechanism includes a fixed rod and a sliding block, the two ends of the fixed rod are connected to the opposite side walls of the waist auxiliary groove, the sliding block is sleeved on the fixed rod and moves along the direction of the fixed rod, and the waist strap is connected to the sliding block.

[0020] By adopting the above technical solution, the fixed rod provides a stable linear movement path, ensuring accurate positioning when the sliding block moves the lumbar strap, adapting to the left and right position differences of different patients' waists, with a small gap between the sliding block and the fixed rod, no jamming or offset during movement, convenient and efficient adjustment, and quick completion of lumbar strap position calibration. The structure has high strength, can withstand the tension of the lumbar strap, is not easily deformed after long-term use, ensuring the stability of the lumbar fixation effect, and the structure is easy to disassemble, making it easy to clean and maintain, reducing the cost of using the device.

[0021] The present invention is further configured such that: a high-definition camera and a speaker are provided on the base plate, and a PLC controller is provided inside the base plate. The PLC controller is simultaneously connected to the high-definition camera, the speaker and the binocular laser rangefinder, and the PLC controller integrates an intelligent detection system.

[0022] By adopting the above technical solution, a high-definition camera captures real-time images of the patient's posture, a speaker enables voice interaction, and a binocular laser rangefinder collects precise parameters. These three components work together through a PLC controller, replacing the subjective judgment of traditional manual testing, improving the objectivity and accuracy of the test. At the same time, the PLC controller, as a control unit, can realize real-time data transmission, processing, and command issuance, simplifying the testing process, reducing manual operation steps, and improving testing efficiency. Furthermore, the integration of the intelligent testing system enables the testing device to have automated testing capabilities, reducing reliance on professional medical personnel, and facilitating its promotion and use in primary healthcare institutions or community health service centers, thus expanding the testing coverage.

[0023] The present invention is further configured such that: the intelligent detection system includes an attitude acquisition module, an attitude determination module, a parameter measurement module, a disease analysis module, and an audio broadcasting module;

[0024] The posture acquisition module is used to receive posture image data of the patient during the detection process in real time from the high-definition camera, and transmit the posture image data to the posture determination module.

[0025] The posture determination module pre-stores a standard posture template for detecting ankylosing spondylitis patients. By receiving posture image data forwarded by the posture acquisition module, it compares the posture image data with the standard posture template to generate a posture standard determination result. If the determination result is non-standard, it sends a posture adjustment command to the audio broadcasting module. If the determination result is standard, it sends a measurement start command to the parameter measurement module.

[0026] The parameter measurement module is used to receive the measurement start command sent by the posture determination module, start to acquire the key dimension parameters of the patient's current posture in real time by the binocular laser rangefinder, generate posture parameter data and directly transmit it to the condition analysis module.

[0027] The disease analysis module pre-stores ankylosing spondylitis disease grading assessment model. By receiving posture parameter data transmitted by the parameter measurement module, it performs quantitative analysis on the posture parameter data, generates a patient's disease severity assessment result, and simultaneously sends the result broadcast command and the disease severity assessment result to the audio broadcast module.

[0028] The audio broadcasting module is used to receive posture adjustment instructions from the posture determination module or result broadcasting instructions from the disease analysis module. When receiving a posture adjustment instruction from the posture determination module, it broadcasts a preset posture adjustment reminder voice. When receiving a result broadcasting instruction from the disease analysis module, it broadcasts the patient's current posture parameters and the assessment results of the severity of the disease.

[0029] By adopting the above technical solution, the posture acquisition module captures the patient's posture in real time, and the posture judgment module compares it with a standard template to ensure that the detection posture is standard, avoiding detection errors caused by non-standard posture. The audio broadcast module provides timely feedback on posture adjustment instructions, improving patient cooperation. The parameter measurement module automatically starts measurement after the posture meets the standard, ensuring the timeliness and accuracy of parameter acquisition. The disease analysis module quantifies and analyzes parameters through a preset assessment model, generating objective assessment results of the severity of the disease, replacing traditional manual experience judgment and improving the scientific nature of diagnosis. The audio broadcast module broadcasts the detection parameters and assessment results in real time, allowing patients and medical staff to intuitively understand the detection situation, improving the transparency of the detection. The overall process realizes a complete process of posture calibration - automatic measurement - intelligent analysis - result feedback, which greatly improves detection efficiency and diagnostic reliability.

[0030] The present invention is further configured such that the comparison process of the posture determination module is as follows: extracting key points of the human skeleton from the posture image data, including key points of the cervical spine, thoracic spine, lumbar spine, hip joint, knee joint, and ankle joint; calculating the relative angles and spacing between each key point and the deviation values ​​from the standard posture template; when all deviation values ​​are within the preset threshold range, the posture is determined to be standard and a measurement start command is sent to the parameter measurement module; otherwise, the posture is determined to be non-standard and an adjustment reminder command is sent to the audio broadcast module, while triggering the posture acquisition module to continue acquiring posture image data and repeating the posture determination process.

[0031] By employing the above technical solution, and extracting key points of the human skeleton, the deviation values ​​of relative angles and spacing from the standard template are calculated to achieve precise judgment of the patient's posture. This avoids the subjective errors of human overall perception in traditional posture judgment. A preset deviation threshold range ensures the consistency and objectivity of the judgment standard, allowing different operators to obtain consistent judgment results and improving the repeatability of the detection. When the posture is not standard, a loop of data collection and adjustment reminders is triggered until the posture is up to standard before measurement is initiated. This avoids parameter errors caused by posture problems from the source, ensuring the reliability of subsequent disease analysis results. The accurate extraction of key points and deviation calculation provide medical staff with specific data on posture abnormalities, facilitating targeted guidance for patients to adjust their posture and improving the professionalism and personalization of the detection.

[0032] In summary, the present invention has the following beneficial effects:

[0033] 1. This invention standardizes and objectifies the testing process, greatly improving data quality. By transforming the traditional manual examination, which relies on the subjective experience of physicians and the cooperation of patients, into objective measurement on a standardized hardware platform, and utilizing the combined effects of body protection, joint assistance, and lumbar support mechanisms, it accurately guides patients into and maintains standard testing positions that conform to medical norms, such as lumbosacral contact and knee extension. This fundamentally eliminates measurement errors caused by inconsistent postures. At the same time, it ensures that the data obtained when testing the same patient (or different patients) at different times, in different environments, by different operators, and in different environments can be directly, effectively, and meaningfully compared and analyzed. This provides a reliable and consistent quantitative basis for longitudinal monitoring of disease progression and evaluation of treatment effectiveness.

[0034] 2. The intelligent detection system integrated in this invention realizes a fully automated closed-loop process of "visual recognition - posture determination - voice guidance - precise measurement - intelligent analysis - result broadcasting". Through intelligent guidance and quality control, the system can actively identify whether the patient's posture meets the standards and provide real-time voice guidance for adjustment, ensuring that each key measurement is triggered in the optimal posture, thus guaranteeing the validity of the data from the source. At the same time, using a pre-set disease grading assessment model, the system quantifies and analyzes the body parameters obtained by the high-precision laser rangefinder, directly generating objective disease severity assessment results, which greatly reduces the bias of doctors' subjective judgment.

[0035] 3. This invention utilizes a sliding mechanism to enable the binocular laser rangefinder to flexibly and stably align with the measurement point, ensuring the accuracy and repeatability of optical measurements. At the same time, the adjustable body protection mechanism (telescopic rod, elastic rope) can effectively prevent patients from having accidents due to pain or imbalance during the test without restricting necessary activities, significantly improving the safety of the test process. The joint and waist auxiliary mechanisms are equipped with adjustable components, which can easily adapt to the physiological structure of patients of different heights and body types, providing effective fixation while taking into account the patient's comfort and individual needs.

[0036] 4. The automated process of this invention reduces the time spent by doctors on repeated guidance, manual measurement and recording, shortens the time of a single test, and increases the diagnostic efficiency. At the same time, the standardized intelligent process reduces the over-reliance on the examiner's personal experience, which helps to promote standardized ankylosing spondylitis postural assessment in medical institutions at all levels. The quantitative and standardized postural parameters and preliminary analysis results obtained during the test can provide rheumatologists with more intuitive and reliable objective references, assisting them in making more accurate diagnoses and disease assessments. It has good clinical application prospects and market value. Attached Figure Description

A sliding mechanism is mounted on the side plates 2, and a sliding frame 3 is mounted on the sliding mechanism. The sliding mechanism is used to adjust the relative position of the sliding frame 3 and the side plates 2. By adjusting the position of the sliding frame 3 using the sliding mechanism, the binocular laser rangefinder 4 can be flexibly moved to adapt to the detection needs of patients of different heights and body types, thus expanding the applicability of the device.

[0048] In this preferred embodiment, the body protection mechanism includes a telescopic rod 8, a U-shaped frame 9, a limiting block 10, and an elastic rope 11. The fixed end of the telescopic rod 8 is hinged to the base plate 1, and the telescopic end is connected to the U-shaped frame 9. One end of the elastic rope 11 is connected to the base plate 1, and the other end passes through the U-shaped frame 9 and is connected to the limiting block 10. When measuring occiput-wall, finger-to-ground distance, chest wall mobility, Schober's curve, and scoliosis, the patient needs to maintain an upright posture. To avoid accidents caused by pain or imbalance during the testing process, the patient can pass their arms through the body protection mechanism. At this time, the U-shaped frame 9 is fixed to the patient's shoulder. At the same time, the telescopic rod 8 can be used to flexibly adjust the length and angle to adapt to the protection needs of different parts of the patient's body. The U-shaped frame 9 provides stable support for the elastic rope 11, avoiding the rope from directly contacting the patient and causing local pressure. The elastic rope 11 has good elasticity, which can not only play a protective and limiting role, but also will not affect the patient's breathing or blood circulation due to excessive restraint, thus improving the comfort of the examination. The limiting block 10 can adjust the tightness of the elastic rope 11 according to the patient's body shape, ensuring the protective effect while taking into account individual differences.

Patients can cooperate to complete the strap fixation themselves, improving the testing efficiency.

[0050] In this preferred embodiment, the adjustment mechanism includes a fixed rod 15 and a sliding block 16. The two ends of the fixed rod 15 are connected to the opposite side walls of the joint auxiliary groove 14.

The fixed rod 15 provides a stable moving track for the sliding block 16, ensuring that the sliding block 16 does not deviate during movement, thereby ensuring that the position adjustment of the joint strap 12 is precise and controllable. The sleeve structure between the sliding block 16 and the fixed rod 15 is simple, with low movement resistance and smooth adjustment process. The joint strap 12 can be quickly adjusted to the target position. This structure has strong load-bearing capacity and can stably support the tension of the joint strap 12, avoiding deformation or loosening after long-term use and extending the service life of the mechanism.

A lumbar support groove 18 is provided on the base plate 1, and the adjustment mechanism is located within the lumbar support groove 18. The lumbar strap 17 is connected to the adjustment mechanism, which is used to adjust the position between the lumbar strap 17 and the base plate 1. The movable buckle 13 is located on the lumbar strap 17 and is used to adjust the tightness of the lumbar strap 17. The adjustment mechanism moves the lumbar strap 17 within the lumbar support groove 18, adapting to the needs of patients with different lumbar circumferences. This ensures the strap fits snugly against the waist. The movable buckle 13 adjusts the tightness of the strap, allowing the patient's waist to be close to the base plate 1, avoiding postural instability caused by waist swaying during testing, while also preventing excessive tightness from compressing the lumbar muscles or spine, thus improving patient comfort. This mechanism effectively fixes the lumbar posture, ensuring the stability of key areas such as the lumbar spine and hip joints, providing accurate conditions for the laser rangefinder to collect parameters such as spinal curvature and the fit between the waist and the base plate 1, ensuring the accuracy of the condition assessment.

[0052] In this preferred embodiment, the adjustment mechanism includes a fixed rod 15 and a sliding block 16.

The adjustment is convenient and efficient, and the position calibration of the lumbar strap 17 can be completed quickly.

[0053] In this preferred embodiment, a high-definition camera 19 and a speaker 20 are mounted on the base plate 1. A PLC controller 21 is installed inside the base plate 1. The PLC controller 21 is communicatively connected to the high-definition camera 19, the speaker 20, and the binocular laser rangefinder 4. The PLC controller 21 integrates an intelligent detection system. The high-definition camera 19 is a high-definition infrared camera that supports normal acquisition of posture image data in light intensity environments of 0-1000 lux. It also has an automatic wake-up function for human detection. When a human body is detected entering the preset detection area, the posture acquisition process is automatically started and the initial posture is transmitted to the posture determination module 24. Image data, speaker 20 for voice interaction, and binocular laser rangefinder 4 for collecting precise parameters—these three work together through PLC controller 21 to replace the subjective judgment of traditional manual inspection, improving the objectivity and accuracy of the inspection. At the same time, PLC controller 21, as a control unit, can realize real-time data transmission, processing, and command issuance, simplifying the inspection process, reducing manual operation steps, and improving inspection efficiency. Furthermore, the integration of the intelligent inspection system enables the inspection device to have automated inspection capabilities, reducing reliance on professional medical personnel and facilitating its promotion and use in primary medical institutions or community health service centers, thus expanding the inspection coverage.

[0054] In this preferred embodiment, the intelligent detection system includes a posture acquisition module 23, a posture determination module 24, a parameter measurement module 25, a condition analysis module 26, and an audio broadcasting module 27. In this embodiment, the posture acquisition module 23 receives posture image data of the patient in real time from the high-definition camera 19 during the detection process and transmits the posture image data to the posture determination module 24. The comparison process of the posture determination module 24 is as follows: extracting key points of the human skeleton from the posture image data, including key points of the cervical spine, thoracic spine, lumbar spine, hip joint, knee joint, and ankle joint; calculating the relative angles and spacing between each key point and the deviation values ​​from the standard posture template; when all deviation values ​​are within the preset threshold range, the posture is determined to be standard and a measurement start command is sent to the parameter measurement module 25; otherwise, the posture is determined to be non-standard and an adjustment reminder command is sent to the audio broadcasting module 27, while triggering the posture acquisition module 23 to continue acquiring posture image data and repeating the posture determination process.

[0055] In this embodiment, the posture determination module 24 pre-stores a standard posture template for detecting ankylosing spondylitis patients. By receiving posture image data forwarded by the posture acquisition module 23, it compares the posture image data with the standard posture template to generate a posture standard determination result (standard / non-standard). If the determination result is non-standard, a posture adjustment command is sent to the audio broadcasting module 27. If the determination result is standard, a measurement start command is sent to the parameter measurement module 25. The posture acquisition module 23 and the posture determination module 24 use real-time data stream transmission with a transmission delay of no more than 100ms. The parameter measurement module 25 and the disease analysis module 26 use encrypted data transmission to ensure the security of posture parameter data.

[0056] In this embodiment, the parameter measurement module 25 is used to receive the measurement start command sent by the posture determination module 24, and start acquiring the key dimension parameters of the patient's current posture in real time by the binocular laser rangefinder 4 (including the distance associated with the spinal curvature angle, the distance between limb extensions, the vertical distance between the trunk and the ground, etc.), generate posture parameter data, and directly transmit it to the disease analysis module 26; wherein the measurement process of the binocular laser rangefinder 4 is synchronously triggered by the posture determination module 24, and the three-dimensional coordinates of the key points of the human skeleton are located by binocular vision, and the key dimension parameters are calculated based on the three-dimensional coordinates. The sampling frequency of the measurement data is not less than 10Hz, and the measurement error does not exceed ±0.5cm.

[0057] In this embodiment, the disease analysis module 26 pre-stores ankylosing spondylitis disease grading assessment model. By receiving posture parameter data transmitted by the parameter measurement module 25, it performs quantitative analysis on the posture parameter data to generate a patient's disease severity assessment result (including mild, moderate, and severe, and corresponding quantitative indicators). The result broadcast command and the disease severity assessment result are simultaneously sent to the audio broadcast module 27. The disease grading assessment model is constructed based on the clinical ankylosing spondylitis disease assessment standard (including BASDAI score and spinal mobility score correlation index). By matching the posture parameter data with the preset grading threshold in the model, the corresponding disease severity assessment result is generated. The model supports updating the grading threshold parameters based on clinical data.

[0058] In this embodiment, the audio broadcasting module 27 is used to receive posture adjustment instructions from the posture determination module 24 or result broadcasting instructions from the disease analysis module 26. When receiving the posture adjustment instruction from the posture determination module 24, it broadcasts a preset posture adjustment reminder voice. When receiving the result broadcasting instruction from the disease analysis module 26, it broadcasts the patient's current posture parameters and the assessment results of the severity of the disease. At the same time, the audio broadcasting module 27 supports voice customization function, and can modify the content, speech rate and volume of the posture adjustment reminder voice through an external input device, and supports multi-language broadcasting switching.

[0059] In this embodiment, the posture acquisition module 23 captures the patient's posture in real time, and the posture judgment module 24 compares the posture with a standard template to ensure that the detection posture is standard and avoids detection errors caused by non-standard posture. The audio broadcast module 27 provides timely feedback on posture adjustment instructions to improve patient cooperation. The parameter measurement module 25 automatically starts measurement after the posture meets the standard to ensure the timeliness and accuracy of parameter acquisition. The disease analysis module 26 quantifies and analyzes parameters through a preset assessment model to generate objective disease severity assessment results, replacing traditional manual experience judgment and improving the scientific nature of diagnosis. The audio broadcast module 27 broadcasts the detection parameters and assessment results in real time, allowing patients and medical staff to intuitively understand the detection situation and improve the transparency of detection. The overall process realizes a complete process of posture calibration-automatic measurement-intelligent analysis-result feedback, which greatly improves detection efficiency and diagnostic reliability.

[0060] Working principle: When performing tests for occiput-wall measurement, finger-to-ground distance measurement, thoracic mobility measurement, Schober measurement, and scoliosis measurement, the testing device is placed upright. When measuring hip joint mobility, the testing device is placed horizontally. Depending on the measurement item, joint assist mechanisms are selectively used to fix the knee joint, and lumbar assist mechanisms are used to fix the waist. The body protection mechanism is deployed to form a safety protection. Then, the sliding mechanism adjusts the binocular laser rangefinder 4 to the appropriate testing position. The high-definition camera 19 collects the patient's posture image in real time. The posture acquisition module 23 of the PLC controller 21 receives the data and transmits it to the posture determination module 24. The posture determination module 24 extracts the key points of the skeleton and compares them with the standard posture template. If the deviation exceeds the threshold, the speaker 20 broadcasts the adjustment command until the posture meets the standard. After the posture meets the standard, the parameter measurement module 25 is activated. The binocular laser rangefinder 4 collects key parameters such as spinal curvature and joint angles and transmits them to the condition analysis module 26. The condition analysis module 26 quantifies and analyzes the parameters through a preset evaluation model and generates the result of the severity of the condition. Finally, the audio broadcast module 27 broadcasts the posture parameters and evaluation conclusions to complete the testing process.
