Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to a joint function assessment system. Background Art
[0002] The primary goal of surgery and rehabilitation is to restore limb joint function. Currently, assessing limb joint function mainly relies on measurements taken by physicians during routine outpatient follow-ups of the target limb joints. However, this method is time-consuming, inefficient, and has limited accuracy. While some tools and instruments exist specifically for measuring single-joint range of motion, their applicability is limited and their accuracy is unsatisfactory. Wearable devices are also available for measuring limb range of motion, but the wearing process is cumbersome and inefficient. Utility Model Content
[0003] The purpose of this invention is to provide a joint function assessment system that can achieve high-precision and rapid assessment of a patient's limb function.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A joint function assessment system includes an assessment room and an image acquisition device, a biomechanical measurement device, a data collection device, a data analysis device, and a guidance device disposed in the assessment room. The image acquisition device, the biomechanical measurement device, and the data analysis device are all electrically connected to the data collection device.
[0006] Users perform preset test items in the evaluation room. The image acquisition device is used to collect the user's image information and can feed the image information back to the data collection device. The mechanical measurement device is used to collect the user's mechanical information and can feed the mechanical information back to the data collection device. The data collection device can feed the video information and mechanical information back to the data analysis device. The data analysis device can analyze the image information and mechanical information respectively and output the analysis results. The guidance device can provide test guidance to the user based on the analysis results of the image information.
[0007] In some possible implementations, the assessment room is also equipped with a gait measuring device, which is electrically connected to the data collection device. The gait measuring device is used to collect the user's gait information and can feed back the gait information to the data collection device, which in turn feeds back the gait information to the data analysis device.
[0008] In some possible implementations, the evaluation room includes a measurement room and a guidance room, with the image acquisition device and the mechanical measurement device both located in the measurement room, and the data collection device and the data analysis device both located in the guidance room.
[0009] In some possible implementations, the guidance device includes an audio-visual module and a monitoring module electrically connected to the audio-visual module, wherein the audio-visual module is located in the measurement room and the monitoring module is located in the guidance room.
[0010] In some possible implementations, an observation window is provided between the measuring chamber and the guidance chamber.
[0011] In some possible implementations, the mechanical measuring device includes a counterweight and a mechanical measuring instrument, which is electrically connected to the data collection device.
[0012] In some possible implementations, the image acquisition device is a camera.
[0013] In some possible implementations, a storage database for storing data is also included, with both the data collection device and the data analysis device electrically connected to the storage database.
[0014] In some possible implementations, the evaluation chamber is also equipped with a test bed and chair.
[0015] The beneficial effects of this utility model are:
[0016] This utility model provides a joint function assessment system. During indoor testing, the user performs corresponding movements and biomechanical measurements, specifically referring to existing technologies. An image acquisition device acquires images, a biomechanical measurement device acquires biomechanical information, and a data collection device collects this information and feeds it back to a data analysis device. The data analysis device analyzes the image and biomechanical information separately. It determines whether the image analysis results meet preset requirements, i.e., whether the user's movements meet the requirements. If not, it corrects the spatial activity of the user's single joint to prevent compensatory movements of other joints from interfering with the measurement results, thereby improving measurement accuracy. If the user's movements meet the requirements, it comprehensively measures and feeds back muscle strength information based on the image and biomechanical information. After analyzing the range of motion and biomechanical information, it simulates and analyzes the feasibility of the human body performing common daily movements under these conditions. Finally, it integrates data such as range of motion, biomechanics, and daily movement analysis to generate an analysis report and provides corresponding scores based on commonly used clinical joint scoring methods.
[0017] The joint function assessment system utilizes image acquisition, biomechanical measurement, data collection, data analysis, and guidance devices. Users can complete joint function assessments simply by following movements, eliminating the need for wearable equipment and simplifying operation, thus improving testing and assessment efficiency. During the process, image and biomechanical information is acquired in real-time and stored in a database, while simultaneous analysis enhances reliability and accuracy. Furthermore, the system comprehensively evaluates limb function by simultaneously analyzing range of motion, biomechanical, and muscle strength information, further improving reliability. Multimodal measurement meets the needs of comprehensive functional assessment. Attached Figure Description

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a joint function assessment system, including an assessment room 1 and an image acquisition device 2, a mechanical measurement device 3, a data collection device 4, a data analysis device 5, and a guidance device 6, all located within the assessment room 1. The image acquisition device 2, mechanical measurement device 3, and data analysis device 5 are all electrically connected to the data collection device 4. The user performs preset test items within the assessment room 1. The image acquisition device 2 collects the user's image information and can feed it back to the data collection device 4. The mechanical measurement device 3 collects the user's mechanical information and can feed it back to the data collection device 4. The data collection device 4 can feed back video and mechanical information to the data analysis device 5. The data analysis device 5 can analyze the image and mechanical information and output the analysis results. The guidance device 6 can provide test guidance to the user based on the analysis results of the image information.
[0027] When the user is tested in assessment room 1, the user performs corresponding movements and biomechanical measurements, specifically referring to existing technology. Image acquisition device 2 acquires images, biomechanical measurement device 3 acquires biomechanical information, and then data collection device 4 collects the above information and feeds it back to data analysis device 5. Data analysis device 5 analyzes the image and biomechanical information. It determines whether the image information analysis results meet the preset requirements, that is, whether the user's movements meet the requirements. If they do not meet the requirements, the spatial movement of the user's single joint is corrected to prevent compensatory movements of other joints from interfering with the measurement results, thereby improving the accuracy of the measurement. If the user's movements meet the requirements, muscle strength information is comprehensively measured and fed back based on the image and biomechanical information. After analyzing the range of motion and biomechanical information, the feasibility of the human body performing common daily movements under these conditions is simulated and analyzed. Subsequently, the analysis report is generated by integrating the data of range of motion, biomechanics, and daily movement analysis, and corresponding scores are provided according to commonly used clinical scoring methods for joints. The joint function assessment system utilizes image acquisition device 2, biomechanical measurement device 3, data collection device 4, data analysis device 5, and guidance device 6. Users can complete joint function assessments simply by following movements, eliminating the need for wearable devices and simplifying operation, thus improving testing and assessment efficiency. During the process, image and biomechanical information is acquired in real-time and stored in a database, while simultaneous analysis enhances reliability and accuracy. The system comprehensively evaluates limb function by simultaneously analyzing range of motion, biomechanical, and muscle strength information, further improving reliability. Multimodal measurement meets the needs of comprehensive functional assessment.
[0028] For example, during the testing process, the user is the patient, and the preset test items are the doctor's prescription for the assessment area based on the patient's condition. The technician selects the corresponding examination items according to the prescription. The patient enters the assessment room 1 for testing, and the technician can view and analyze the results. When it is determined that the user's movements do not meet the requirements, the spatial movement of the user's single joint will be corrected through the guidance device 6.
[0029] Assessment Room 1 comprises a measurement room 11 and a guidance room 12. Image acquisition equipment 2 and mechanical measurement equipment 3 are both located in the measurement room 11, while data collection equipment 4 and data analysis equipment 5 are both located in the guidance room 12. Users undergo testing in the measurement room 11, while technicians observe and provide guidance in the guidance room 12. These two rooms are separate to prevent mutual interference and ensure accurate test results. An observation window 13 connects the measurement room 11 and the guidance room 12, allowing for timely observation of the patient's condition to prevent accidents. Furthermore, it enables technicians to provide reminders and guidance when the patient's movements deviate significantly.
[0030] The guidance device 6 includes an audio-visual module 61 and a monitoring module 62 electrically connected to the audio-visual module 61. The audio-visual module 61 is located in the measurement room 11, and the monitoring module 62 is located in the guidance room 12. The audio-visual module 61 can specifically be a display screen and speakers, etc., and the monitoring module 62 can be a computer, etc. The technician inputs the corresponding program into the computer, so that the display screen and speakers provide instructional videos and voice guidance, and the patient performs the corresponding actions and biomechanical measurement items.
[0031] The assessment room 1 is also equipped with a gait measuring device 8, which is electrically connected to the data collection device 4. The gait measuring device 8 is used to collect the user's gait information and can feed back the gait information to the data collection device 4. The data collection device 4 feeds back the gait information to the data analysis device 5. By simultaneously analyzing and evaluating limb function through activity, biomechanics, gait and muscle strength information, the reliability is further improved. Multimodal measurement meets the needs of comprehensive functional assessment.
[0032] The mechanical measuring device 3 includes a counterweight and a mechanical measuring instrument. The mechanical measuring instrument is electrically connected to the data collection device 4. Users operate the counterweight and mechanical measuring instrument according to the instructions. The structure is simple and the operation is convenient. The evaluation room 1 is also equipped with a test bed and chair 7, which can be an integrated test bed and chair or separate test bed and chair. Users can use the counterweight or mechanical measuring instrument on the test bed and chair 7. The mechanical measuring instrument and counterweight are existing structures that can be purchased externally, and will not be described in detail here.
[0033] Image acquisition device 2 is a camera, specifically a high-definition camera. The high-definition camera captures video information, enabling three-dimensional spatial vision, measuring the actual movement of joints, and improving accuracy. Multiple high-definition cameras can be deployed to prevent system crashes; and video information can be acquired from multiple angles to further enhance accuracy.
[0034] The joint function assessment system also includes a storage database 9 for storing data. The data collection device 4 and the data analysis device 5 are both electrically connected to the storage database 9, and the data is stored through the storage database 9 for later review.
[0035] like Figures 1-3 As shown, this embodiment also provides a method for using the joint function assessment system as described above, including the following steps:
[0036] S1. The user performs preset test items in evaluation room 1;
[0037] S2, image acquisition device 2 and mechanical measurement device 3 respectively acquire the user's image information and mechanical information, and feed them back to data collection device 4;
[0038] S3. Data collection device 4 feeds back to data analysis device 5, and data analysis device 5 analyzes the image information and mechanical information and outputs the analysis results;
[0039] S4. Determine whether the analysis results of the image information meet the preset requirements; if yes, end the test.
[0040] S5. If not, then based on the analysis results, guide the user to test again through the guidance device 6, and repeat the above steps to achieve a high-precision and rapid assessment of the patient's limb function.
