DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0022] As shown in the accompanying Figure 1 to the accompanying Figure 4 drawings:

[0023] Example one: the present application provides a kind of according to nystagmus positioning damage semicircular canal portable eyeshield, including eyeshield body 2, fixed plate 3 and high-speed camera 6;Two sides in eyeshield body 2 inside are provided with high-speed camera 6, one end of two high-speed cameras 6 is provided with infrared illumination module 8, the inside of eyeshield body 2 of the side close to high-speed camera 6 is provided with inertial measurement unit 5, the inside of eyeshield body 2 of the top of inertial measurement unit 5 is provided with processor 4;One end of eyeshield body 2 is movably installed with fixed plate 3, both sides of eyeshield body 2 are fixedly connected with connecting buckle 10, the outside of connecting buckle 10 is movably installed with headband 1.

[0024] The device adopts a lightweight wearable eyeshade body 2 as a bearing platform, breaks through the limitations of traditional large fixed equipment, and realizes high integration and miniaturization. High-speed cameras 6 are installed on both sides inside the eyeshade body 2, which are used to collect real-time images of the patient's eyeball movement; the front end of the high-speed camera 6 is equipped with an infrared lighting module 8, which provides stable and flicker-free infrared light source in weak or no light environment, reduces the discomfort of the patient and ensures the image clarity. An inertial measurement unit 5 is arranged inside the eyeshade body 2 near one side of the high-speed camera 6, which contains a three-axis accelerometer and a three-axis gyroscope, which can detect the acceleration and angular velocity changes of the patient's head in real time, and is used to eliminate the interference of head movement on nystagmus signal in the later data processing. A processor 4 is integrated inside the top of the eyeshade body 2, which is responsible for receiving the original data of the high-speed camera 6 and the inertial measurement unit 5, and performing nystagmus feature extraction, motion compensation and semicircular canal positioning analysis through the built-in algorithm. A fixed plate 3 is movably installed at one end of the eyeshade body 2, which is used to enhance the stability of the device and the face; the connecting buckle 10 on both sides cooperates with the headband 1 to realize quick wearing and firm fixing, so that the device can be flexibly deployed in various scenes such as clinics, wards and primary medical institutions; the highly integrated portable design, the eyeshade body 2 does not need complex installation and debugging process, the medical staff can quickly complete the device deployment and detection preparation on the spot of patient treatment, greatly shortening the waiting time of the patient, during the detection process, the high-speed camera 6 and the inertial measurement unit 5 work cooperatively to obtain the nystagmus data in real time and transmit it to the processor 4 for processing, through the lightweight eyeshade body 2 and the design of fitting the face, combined with the stable support of the fixed plate 3, the compression and discomfort of the patient when wearing are reduced, and the fatigue caused by long-term cooperation with large equipment detection is reduced, which improves the diagnosis and treatment efficiency and effectively improves the patient's medical experience.

[0025] In an embodiment of the present application, the inner side of the headband 1 is provided with a magic tape 101, and the other end of the eyeshade body 2 is provided with a buffer pad 9.

[0026] When wearing the eyeshade, the headband 1 is wrapped around the head, and the magic tape 101 on the inner side of the headband 1 is used for quick adhesion and fixation. Since the magic tape 101 can adjust the adhesion position according to the head circumference, it can adapt to the head size of different users, solving the problem that the traditional fixed mode is difficult to adjust the tightness flexibly, and ensuring that the headband 1 does not loosen easily during use, ensuring the stability of the position of the eyeshade body 2, so that the core components such as the high-speed camera 6 and the inertial measurement unit 5 are always aligned with the target monitoring area, improving the accuracy of nystagmus data collection, the buffer pad 9 adopts slow rebound memory cotton, which can relieve the pressure of the eyeshade body 2 on the skin, and avoid leaving marks or discomfort after long-term wearing. At the same time, the buffer pad 9 can fill the small gap between the eyeshade body 2 and the face, reduce the entry of external light, create a stable monitoring environment for the high-speed camera 6 and the infrared lighting module 8, and avoid external light interference with the collection quality of the nystagmus image.

[0027] In one embodiment of the present application, the side of the eye mask body 2 is provided with a connection port 7.

[0028] The connection port 7 is an integrated interface provided on the side of the eye mask body 2, which can serve as a power supply interface of the device. It can be directly connected to a power line to supply power to the eye mask during detection, ensuring the continuous and stable operation of power-consuming components such as the high-speed camera 6 and the inertial measurement unit 5. By connecting the eye mask body 2 to an external computer through an external data line, the nystagmus data generated during the detection process and the analysis results can be transmitted to the computer in real time. This not only facilitates doctors to view and monitor the detection process on the screen in real time, but also enables the generation of standardized detection reports using the supporting software and the printing of the reports directly connected to the printer. This realizes efficient processing, display, archiving, and sharing of data, greatly improving the clinical practicality and work efficiency of the eye mask.

[0029] In one embodiment of the present application, the top and bottom of the fixing plate 3 are fixedly connected with pullers 301.

[0030] When it is necessary to disassemble the fixing plate 3 from the eye mask body 2, the user can pinch the pullers 301 on the top and bottom of the fixing plate 3 and apply a pulling force away from the eye mask body 2. The pulling force is transmitted to the fixing plate 3 through the pullers 301, driving the insertion rod 302 to come out of the fixing rod 201. Compared with directly pulling the edge of the fixing plate 3 with hands, the pullers 301 can more easily realize the disassembly operation and avoid skin scratches or component wear caused by direct contact of hands with the edge of the fixing plate 3. When assembling, the position of the fixing plate 3 can be adjusted through the pullers 301, so that the insertion rod 302 can be more accurately aligned with the fixing rod 201, improving the assembly efficiency.

[0031] In one embodiment of the present application, the headband 1 is made of polyester fiber material.

[0032] The polyester fiber material has the characteristics of high strength, good elasticity, and wrinkle resistance. When applied to the headband 1, on the one hand, the high strength characteristic can ensure that the headband 1 is not easily stretched and broken during long-term use, prolonging the service life. On the other hand, the good elasticity allows the headband 1 to stretch flexibly according to the head circumference of the user, closely fitting the head without causing excessive compression.

[0033] The control system of the device is divided into a perception layer, a processing layer, an execution and interaction layer:

[0034] The perception layer is the source of data collection, which is composed of high-speed camera 6, infrared lighting module 8 and inertial measurement unit 5, and works cooperatively under the unified scheduling of processor 4. Processor 4 configures the high frame rate and resolution parameters of high-speed camera 6 through I2C protocol, and starts the collection after receiving the instruction sent by the external computer through the connection port 7, and transmits the continuous eye movement image to the processor 4 in real time. At the same time, processor 4 dynamically adjusts the opening and brightness of infrared lighting module 8 through PWM signal according to the image brightness and clarity feedback by high-speed camera 6, to ensure that stable and flicker-free light source can be provided in weak or no light environment, to ensure image quality and reduce patient discomfort. In addition, processor 4 controls inertial measurement unit 5 through SPI interface, so that it collects three-axis acceleration and three-axis angular velocity of the head at a frequency matched with the camera, and marks each group of data with an accurate time stamp, to provide key raw data for subsequent motion compensation.

[0035] The processing layer is the core of the system, with processor 4 as the core, responsible for deep processing and analysis of the raw data transmitted by the perception layer. First, processor 4 performs preprocessing such as noise reduction and cropping on the images transmitted by high-speed camera 6, and calibrates and filters the motion data of inertial measurement unit 5, then accurately fuses the two types of data according to the time stamp to form a "image-motion" synchronous data set. Then, processor 4 runs the built-in motion compensation algorithm, uses the head motion information provided by inertial measurement unit 5 to correct the eye movement trajectory captured by high-speed camera 6 in real time, effectively offsets the interference of head shaking, and separates the pure nystagmus signal. Finally, processor 4 extracts frequency, amplitude, direction and other characteristic parameters from the corrected nystagmus signal, combines with the head position information, and generates a structured detection report containing waveform graph and positioning conclusion through the pre-set clinical model for positioning analysis of the damaged semicircular canal, and temporarily stores it in the local.

[0036] Execution and interaction layer control: The execution and interaction layer is responsible for the physical stability, energy supply and external communication of the device, ensuring the reliable operation of the system and efficient interaction with the doctor. In terms of physical stability, the fixed plate 3 enhances the fit of the eye shield body 2 and the face through the embedded structure, and the processor 4 can monitor its installation state through the micro switch, and the connection buckle 10 cooperates with the headband 1 to realize quick wearing and firm fixation, adapt to patients with different head circumferences, and ensure the position stability of the high-speed camera 6 and the inertial measurement unit 5 during detection; In terms of energy supply, the connection port 7 serves as a power supply interface, which can directly power the system in wired mode, or charge the built-in battery, and the power management module integrated in the processor 4 distributes stable voltage to the high-speed camera 6, infrared illumination module 8, inertial measurement unit 5, etc., and has low power protection and energy consumption optimization functions; In terms of external communication, the processor 4 establishes a data link with the external computer system through the connection port 7, transmits the real-time processed nystagmus data and the final detection report to the computer, realizes the display, storage and printing of the report, and completes the entire diagnosis and treatment process.

[0037] Working principle: The device acquires continuous images of patient eye movement in real time through the high-speed camera 6, and at the same time provides constant and flicker-free infrared light source by the infrared illumination module 8, ensuring clear eye movement images under various lighting conditions, and the inertial measurement unit 5 synchronously detects the three-dimensional acceleration and angular velocity changes of the patient's head and transmits the data to the processor 4 in real time. The processor 4 receives image data from the high-speed camera 6 and motion data from the inertial measurement unit 5, extracts eye movement features using image recognition algorithms, and combines head motion data for motion compensation to eliminate the interference of head shaking on nystagmus signals. The processor 4 further calculates the frequency, amplitude, direction and other parameters of nystagmus through the built-in nystagmus analysis algorithm, judges the location and functional state of the damaged semicircular canal according to the semicircular canal function positioning model, and finally outputs the detection result. The integrated portable design realizes the miniaturization and portability of the device, supporting rapid deployment and use in clinics, wards and even primary medical institutions in various scenes.

[0038] Embodiment two: This embodiment is basically the same as the previous embodiment, the difference is that in an embodiment of the present application, the two sides inside the eye shield body 2 are fixedly connected with fixed rods 201, one end of the fixed plate 3 is fixedly connected with an insertion rod 302, and the insertion rod 302 is embedded with the fixed rod 201.

[0039] When the core components such as the high-speed camera 6, the inertial measurement unit 5, the processor 4, etc. inside the eye cover body 2 need to be overhauled or maintained, the pull buckle 301 on the fixing plate 3 is pulled to drive the insertion rod 302 at one end of the fixing plate 3 to be detached from the fixing rods 201 on both sides inside the eye cover body 2, so that the fixing plate 3 and the eye cover body 2 are quickly disassembled, and the internal components are directly contacted by the staff for operation; after the overhaul is completed, the insertion rod 302 is re-embedded into the fixing rod 201, and the assembly and fixation of the fixing plate 3 are completed. The embedded structure does not need additional tools, simplifies the disassembly process, and at the same time ensures the stability of the fixing plate 3 and the eye cover body 2 after being connected, avoiding the exposure or damage of the internal components caused by the loosening of the fixing plate 3 during use.

[0040] Working principle: when the core components such as the high-speed camera 6, the inertial measurement unit 5, the processor 4, etc. inside the eye cover body 2 need to be overhauled or maintained, the pull buckle 301 on the fixing plate 3 is pulled to drive the insertion rod 302 at one end of the fixing plate 3 to be detached from the fixing rods 201 on both sides inside the eye cover body 2, so that the fixing plate 3 and the eye cover body 2 are quickly disassembled, and the internal components are directly contacted by the staff for operation; after the overhaul is completed, the insertion rod 302 is re-embedded into the fixing rod 201, and the assembly and fixation of the fixing plate 3 are completed.
