Description

Technical Field

[0001] This invention relates to the field of ophthalmic examination technology, specifically to a modular integrated rapid ophthalmic screening vehicle and its examination method. Background Technology

[0002] Eye screening is a preventative medical service that uses a systematic and standardized examination process and professional medical equipment and technology to comprehensively assess the eye health status of a population and identify early risks. Its core purpose is to detect potential problems such as visual abnormalities, ocular surface diseases, anterior segment lesions, fundus lesions, and ocular complications caused by systemic diseases in a timely manner through non-invasive or minimally invasive examinations, with particular attention to early lesions in the asymptomatic stage. The screening process usually includes multi-dimensional testing such as visual acuity testing, intraocular pressure measurement, slit-lamp microscopy, fundus photography, and optical coherence tomography, combined with artificial intelligence image analysis technology to improve diagnostic efficiency and accuracy. Finally, it provides individuals with personalized health management advice or referral guidance through risk assessment models.

[0003] Chinese patent CN217793006U discloses an early screening device for keratoconus in adolescents. This device features an adjustable structure. Specifically, when the position of the screening lens body needs adjustment, a first motor within the vertical block drives a threaded rod and a threaded block to rotate within the chamber. The threaded connection between the threaded rod and the threaded block causes the threaded block to move to the right within the chamber. This movement, via a transmission block, causes the threaded block to move the vertical plate at the top of the vertical block and the screening lens body to the right, thus adjusting the position of the screening lens body. This facilitates the use of the screening lens body by doctors, enabling them to perform normal screening for keratoconus in adolescents. This improves the efficiency of ophthalmic disease screening to a certain extent, effectively enhancing the practicality of the screening lens body and achieving convenient adjustment of its position.

[0004] Most existing ophthalmic examination equipment adopts an integrated design, with core functional units deeply bound to a dedicated host. This not only results in complex equipment structures and high maintenance costs, but also makes it impossible to flexibly add or remove functional modules according to the actual needs of different screening scenarios. In addition, these devices are large in size and difficult to deploy, making it difficult to quickly deploy them to areas with scarce medical resources such as communities, rural areas, and remote schools. Ultimately, this limits the coverage of ophthalmic screening services and reduces screening efficiency. Summary of the Invention

The two magnetic plates are respectively embedded in the outer wall of the limiting plate and the front inner wall of the light-shielding frame, and the magnetic poles of the two magnetic plates are opposite. The light-shielding cloth is installed between the limiting plate and the rear inner wall of the light-shielding frame, and the light-shielding cloth is configured as a folded structure.

[0019] Furthermore, the dimming mechanism includes a heat dissipation base, multiple LED bulbs, a storage slot, a driving component, a dimming turntable, and multiple filters. The heat dissipation base is installed on the inner top wall of the screening vehicle body. The multiple LED bulbs are embedded in the bottom periphery of the heat dissipation base.

The dimming turntable is installed at the output end of the driving component, and the top of the dimming turntable is mounted to the bottom of the heat dissipation base via a bearing. The multiple filters are embedded in a ring at the bottom of the dimming turntable.

[0020] Furthermore, the lifting mechanism includes a lifting table, a support beam, two electric lifting columns, two support bases, and a distance measuring sensor. The support beam is installed at the bottom end of the lifting table, the two electric lifting columns are respectively installed on both sides of the bottom end of the support beam, the two support bases are respectively installed at the bottom ends of the two electric lifting columns, and both support bases are installed on the bottom inner wall of the screening vehicle body.

[0024] A modularly integrated rapid ophthalmic screening vehicle examination method includes the following steps:

[0025] Step 1, Equipment Adjustment: When an ophthalmological examination is required, the patient enters the screening vehicle and sits in front of the lifting table of the lifting mechanism. The height of the lifting table is adjusted according to the patient's height and examination needs by the electric lifting column. The distance sensor can monitor the height of the lifting table in real time.

[0026] Step 2: Constructing the darkroom and adjusting the light: Operate the light-shielding mechanism, pull the limiting plate to slide along the limiting groove to unfold the light-shielding cloth, use the magnetic plate to fix the position, and form an independent darkroom in conjunction with the light-blocking plate; at the same time, adjust the light-adjusting mechanism, and switch the filter by rotating the light-adjusting turntable through the drive component, and adjust the light source mode according to the inspection requirements to jointly construct a standard-compliant bright and darkroom inspection environment.

[0027] Step 3, Vision Test: Medical staff operate an automatic refractometer to automatically measure parameters such as the refractive power of the patient's eyes. The vision chart projector projects the vision chart to a suitable position for the patient to undergo a vision test. The contrast sensitivity tester tests the patient's contrast sensitivity. The test data is transmitted to the host server through an interface for preliminary processing and storage.

[0028] Step 4, Fundus and Intraocular Pressure Detection: Next, fundus imaging is performed. The fundus camera, optical coherence tomography scanner, and wide-angle imaging adapter work in sequence to acquire detailed image information of the patient's fundus. The data is transmitted to the host server through a dual interface. Then, intraocular pressure is detected. A non-contact tonometer is used for preliminary measurement. If more accurate data is needed, a contact applanation tonometer can be used for further detection. The detection data is also transmitted to the host server through a dual interface.

[0029] Step 5: Slit-lamp examination and AI diagnosis: Medical staff operate the slit-lamp module, and the slit-lamp microscope performs a detailed examination of the anterior segment of the patient's eye. The digital imaging device records the examination images and transmits them to the host server through dual interfaces. The host server transmits the collected examination data to the AI-assisted diagnosis module. The CPU chip and AI computing box quickly analyze and diagnose the data, and provide a preliminary diagnostic result.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] (1) This invention utilizes the collaborative work of a vision testing module, a fundus imaging module, an intraocular pressure testing module, a slit lamp module, and an AI-assisted diagnostic module. Furthermore, the devices within each module are efficiently interconnected with the host server via a unified USB-C and HDMI dual interface. This allows for flexible addition or removal of functional modules according to the needs of different screening scenarios, solving the problems of complex structure and difficult deployment of traditional integrated equipment. It also enables multi-dimensional testing such as refractive error detection, fundus imaging, and intraocular pressure measurement through the professional equipment of each module, significantly improving screening efficiency and diagnostic accuracy, and effectively expanding the coverage of ophthalmic screening services.

[0032] (2) The present invention constructs a standardized bright and dark room environment that adapts to different ophthalmic examination needs through the coordinated work of the light-shielding mechanism and the light-switching mechanism. By pulling the limiting plate along the limiting groove, the folded light-shielding cloth can be quickly unfolded and formed into an independent dark room with the light-blocking plate, effectively isolating external stray light interference. By driving the dimming turntable to rotate through the driving component, the light source mode can be flexibly adjusted, which not only meets the bright room conditions required for vision testing, but also adapts to the dark room environment required for projects such as fundus imaging.

[0033] (3) The present invention achieves precise adaptation and stable support of the examination position through the coordinated work of the lifting table, support beam, electric lifting column, support base and distance sensor. The electric lifting column can smoothly adjust the height of the lifting table according to the height of different examinees and the requirements of the examination items. At the same time, the distance sensor monitors the distance between the support beam and the inner wall of the screening vehicle body in real time and feeds the height data back to the control system to achieve precise positioning of the lifting table and improve the convenience and comfort of the examination operation.

The non-contact tonometer 232 and the contact applanation tonometer 233 are arranged sequentially from top to bottom inside the third storage cabinet 231.

[0059] The slit lamp module 24 includes a fourth storage cabinet 241, a slit lamp microscope 242, and a digital imaging device 243, which can observe the lesions of the anterior segment of the eye in detail. The outer wall of the fourth storage cabinet 241 is installed on the inner side wall of the screening vehicle body 1, and the slit lamp microscope 242 and the digital imaging device 243 are arranged in the fourth storage cabinet 241 from top to bottom.

[0060] The AI-assisted diagnostic module 25 includes a fifth storage cabinet 251, a CPU chip 252, and an AI computing box 253. It uses AI algorithms to quickly analyze examination data and provide preliminary diagnostic results. The CPU chip 252 is a spare chip with the same specifications as the main chip built into the AI ​​computing box 253. It can be used to replace the chip in the AI ​​computing box 253 when it is damaged. The outer wall of the fifth storage cabinet 251 is installed on the inner side wall of the screening vehicle body 1.

The USB-C interface is used for high-speed data transmission and power supply, while the HDMI interface is used for high-definition image preview, making data transmission between devices more convenient and efficient, avoiding interface incompatibility issues. At the same time, the dual-interface design also provides more connection options, enhancing the flexibility and expandability of the devices.

[0062] Working principle: The screening vehicle body 1 provides a mobile support base, and the vision testing module 21, fundus imaging module 22, intraocular pressure testing module 23, slit lamp module 24, and AI-assisted diagnostic module 25 are sequentially arranged and installed inside the vehicle body. Each module is neatly stored and securely installed in the first to fifth storage cabinets. Among them, the vision testing module 21, with its automatic optometry instrument 212, visual acuity chart projector 213, and contrast sensitivity tester 214, can quickly measure refractive error (myopia / hyperopia / astigmatism), visual acuity (such as E chart, digital chart), and contrast sensitivity, and supports different modes for children and adults; the fundus imaging module 22, with its fundus camera 222, optical coherence tomography scanner 223, and wide-angle imaging adapter, ...

[0063] These devices are all independent functional units, and modules can be flexibly added or removed according to the needs of different screening scenarios such as communities, villages, and remote schools. This solves the problems of complex structure, high maintenance costs, and difficult deployment of traditional integrated devices. At the same time, all functional devices are equipped with USB-C and HDMI dual interfaces of the same standard, which can be efficiently interconnected with the host server 7 to realize the real-time transmission, storage and processing of test data. Together with the lighting lamp 6, they provide basic lighting. Through the coordinated operation of each module, multi-dimensional ophthalmic screening is completed, which greatly improves screening efficiency and diagnostic accuracy, effectively expands the coverage of ophthalmic screening services, and allows areas with scarce medical resources to conveniently obtain high-quality ophthalmic screening services. Ultimately, it realizes mobile, standardized and efficient ophthalmic screening services.

[0064] Example 2:

[0065] This embodiment is basically the same as the previous embodiment, except that the light-shielding mechanism 3 includes a light-shielding frame 31, two limiting grooves 32, a limiting plate 33, two magnetic plates 34, a light-shielding cloth 35, and two light-blocking plates 36. These components can quickly form an independent darkroom. The light-shielding frame 31 is installed between the inner walls of both sides of the screening vehicle body 1. The two limiting grooves 32 are respectively opened on the top inner wall and bottom inner wall of the light-shielding frame 31. The limiting plate 33 is slidably installed between the two limiting grooves 32. The two magnetic plates 34 are respectively embedded in the outer wall of the limiting plate 33 and the front inner wall of the light-shielding frame 31, and the magnetic poles of the two magnetic plates 34 are opposite. The position of the limiting plate 33 is fixed by magnetic force. The light-shielding cloth 35 is installed between the limiting plate 33 and the rear inner wall of the light-shielding frame 31. The light-shielding cloth 35 is set as a folding structure, which is convenient to fold up and unfold. The two light-blocking plates 36 are respectively installed on the upper and lower sides of one end of the light-shielding frame 31 to further enhance the light-shielding effect.

[0066] The dimming mechanism 4 includes a heat dissipation base 41, multiple LED bulbs 42, a storage slot 43, a drive assembly 44, a dimming turntable 45, and multiple filters 46. These components can adjust the light source mode according to inspection requirements. The heat dissipation base 41 is installed on the top inner wall of the screening vehicle body 1 to provide heat dissipation support for the LED bulbs 42. Multiple LED bulbs 42 are embedded in the bottom periphery of the heat dissipation base 41. The storage slot 43 is located in the top center of the heat dissipation base 41. The drive assembly 44 is installed on the bottom wall of the storage slot 43. The drive assembly 44 uses a stepper motor or a servo motor to provide rotational power for the dimming turntable 45. To ensure precise alignment between the filter 46 and the LED bulb 42, the dimming turntable 45 is installed at the output end of the drive assembly 44, and the top of the dimming turntable 45 is mounted on the bottom of the heat sink base 41 via a bearing. A brightness sensor is installed at the side gap of any group of filters 46 at the bottom of the dimming turntable 45, and the light-receiving surface of the brightness sensor is flush with the light-emitting surface of the filter 46. The brightness sensor can monitor and control the light intensity and stability of the light source in real time and in a closed loop. Multiple filters 46 are installed in a ring embedded at the bottom of the dimming turntable 45. By rotating the dimming turntable 45, different filters 46 can be switched to adjust the light source mode.

[0067] Multiple filters 46 include several white light filters, red light filters, and red-free filters. The white light filters allow the LED bulb 42 to emit white light, suitable for general ophthalmic examination environments, providing basic illumination for operators. The red light filters filter out other colors of light, allowing only red light to pass through. Red light is commonly used in ophthalmic examinations to observe the blood vessels in the fundus because it has strong penetrating power and can clearly display the morphology and distribution of blood vessels in the fundus. The red-free filters further filter out red light... The components make the light softer, reducing irritation to the patient's eyes and allowing for better observation of the fine structures of the fundus. The filter is divided into groups of white light filter, red light filter, and red-free light filter, with each group of filters 46 corresponding to the light path of a single LED bulb 42. The total number of filter groups 46 is matched with the number of LED bulbs 42. This design allows the dimming mechanism 4 to flexibly combine various colors and intensities of light according to different examination needs, providing more accurate and suitable lighting conditions for ophthalmic examinations.

[0068] Working principle: A standardized examination lighting environment is constructed through the coordinated operation of the light-shielding mechanism 3 and the dimming mechanism 4: Pulling the limiting plate 33 along the limiting groove 32 allows the folded light-shielding cloth 35 to be quickly unfolded. The position of the limiting plate 33 is fixed by two magnetic plates 34 with opposite magnetic poles. With the help of two light-blocking plates 36 blocking the gap between the top and bottom of the light-shielding cloth 35, an independent darkroom can be formed, effectively isolating external stray light interference, adapting to different ophthalmic examination needs, and the lifting mechanism 5 can be placed in the darkroom for subsequent examinations; The dimming turntable 45 is driven to rotate around the bearing by the drive component 44. Multiple filters 46 are installed in a ring at the bottom of the dimming turntable 45, forming a group of white light filters, red light filters, and non-red light filters. Each group corresponds to the light output path of a single LED bulb 42, and the total number of groups matches the number of LED bulbs 42. The dimming turntable 45 is driven to rotate by the driving component 44, which can accurately switch the correspondence between different types of filters 46 and LED bulbs 42, flexibly adjust the light source mode, and adapt to the lighting environment requirements of different examination items such as vision testing and fundus imaging. Combined with the efficient interconnection between the various module devices and the host server 7, it not only meets the bright room conditions required for vision testing, but also adapts to the dark room environment required for fundus imaging and other items. It solves the pain point of lacking a standard dark room in mobile screening, ensures the imaging quality and detection accuracy of various examination items, and further improves the adaptability of the screening vehicle to complex lighting scenarios.

[0069] Example 3:

[0070] This embodiment is basically the same as the previous embodiment, except that the lifting mechanism 5 includes a lifting table 51, a support beam 52, two electric lifting columns 53, two support bases 54, and a distance sensor 55. These components can adjust the height of the examination table according to the patient's height. The support beam 52 is installed at the bottom of the lifting table 51, the two electric lifting columns 53 are respectively installed on both sides of the bottom of the support beam 52, the two support bases 54 are respectively installed at the bottom of the two electric lifting columns 53, and both support bases 54 are installed on the bottom inner wall of the screening vehicle body 1. The distance sensor 55 is installed in the middle of the bottom of the support beam 52 to monitor the height of the lifting table 51 in real time and ensure the accuracy of the adjustment.

[0071] The support beam 52 is designed with an H-shaped structure. The H-shaped support beam 52 has high strength and stability, and will not deform or be damaged when bearing the weight of the lifting table 51 and the force of the electric lifting column 53. The electric lifting column 53 is a ball screw type lifting structure, which has the advantages of high transmission efficiency, high precision and smooth movement. It can ensure that the lifting table 51 moves smoothly and accurately during the lifting process. It also has a built-in self-locking motor, which can automatically lock the position when the electric lifting column 53 stops running, preventing the lifting table 51 from falling unexpectedly due to external force, thus improving the safety and reliability of the lifting mechanism 5. The detection end of the distance sensor 55 is perpendicular to the bottom inner wall of the screening vehicle body 1, so that the distance sensor 55 can accurately measure the distance between the lifting table 51 and the bottom inner wall of the vehicle body, providing accurate data support for the precise control of the lifting mechanism 5.

[0072] Working principle: The lifting mechanism 5 improves the adaptability of the examination position. After the examinee is seated, the lifting table 51 can be smoothly raised and lowered by the self-locking motor built into the electric lifting column 53, according to the height and position requirements of different examination items. At the same time, the distance sensor 55 installed at the bottom center of the support beam 52, with its detection end facing the inner wall of the vehicle body, monitors the distance between the support beam 52 and the inner wall in real time and feeds back the data, realizing the precise positioning of the lifting table 51. The self-locking motor can ensure that the table is stably locked after adjustment to prevent accidental slippage. The lifting mechanism 5 works in conjunction with the vision detection module 21, fundus imaging module 22 and other examination modules, as well as the light shielding mechanism 3 and the dimming mechanism 4, so that the examinee's eyes are always at the same horizontal reference plane as the lenses of each examination device. With the efficient interconnection of each module device and the host server 7, while ensuring the standardization of the lighting environment and the accuracy of the detection data, it further improves the examinee's examination comfort and operation convenience, allowing the screening vehicle to better adapt to the diverse needs of examinees of different ages and heights.

[0073] Example 4:

[0074] This embodiment is basically the same as the previous embodiment, except that the interior of the large screening vehicle is divided into a bright room examination area, a dark room examination area, a correction training area, and a comprehensive treatment area. The bright room examination area is equipped with multiple workbenches, multiple seats, an eye chart, and a reflector. Each workbench is equipped with a lighting lamp 6 at its top and, as needed, an examination mechanism 2 and a dimming mechanism 4. The structure of the workbench is consistent with the structure of the lifting mechanism 5. The dark room examination area is separated by two light-shielding mechanisms 3. The dark room examination area is equipped with multiple workbenches, multiple seats, and a dimming mechanism 4. The correction training area is equipped with correction equipment and seats. The comprehensive treatment area is equipped with a soft curtain, an examination bed, workbenches, and seats. The structure of the workbenches is also consistent with the structure of the lifting mechanism 5. Each area's dimming mechanism 4 integrates an intelligent lighting control system, achieving adaptive adjustment of the light environment through IoT technology. It can automatically switch lighting modes according to the examination type (such as vision test mode → color vision mode → dark adaptation mode), with a switching time of less than 1 second. It is also equipped with a multispectral sensor array (sampling rate 10Hz) to monitor parameters such as illuminance, color temperature, and color rendering index in real time, automatically adjusting the lamp output with a response time ≤0.5s and illuminance fluctuation ≤±5%. It also has equipment linkage functions, such as automatically turning off irrelevant lighting units when the vision timer is turned on. The entire large screening vehicle meets the service needs of large-scale and multi-scenario operation, enabling parallel operation through functional zoning, while continuing the modular and adjustable design logic to ensure the continuity of screening and initial treatment.

[0075] Working Principle: The large screening vehicle achieves efficient operation through deep adaptation of functional zoning and modular equipment. The bright-room examination area utilizes multiple adjustable workbenches with the same structure as the lifting mechanism 5, accommodating multiple patients for simultaneous basic screening. Medical staff can switch white light filters via the dimming mechanism 4, and, in conjunction with the eye chart, reflector, and vision testing module 21 in the examination mechanism 2, quickly complete refractive error, visual acuity, and contrast sensitivity tests. The lighting 6 at the top of the workbenches provides ample illumination. The intelligent lighting control system automatically adjusts illuminance and color temperature according to the vision test mode. A multispectral sensor array monitors and maintains a stable light environment in real time. Test data is transmitted in real time to the host server 7 via USB-C and HDMI dual interfaces. The dark-room examination area is formed by two light-shielding mechanisms 3 unfolding light-shielding cloths 35 and fixing them with magnetic plates 34 to create a closed environment. Multiple workbenches inside can simultaneously perform fundus imaging, intraocular pressure measurement, and slit-lamp examination. By switching between red light and red-free filters via the dimming mechanism 4, the intelligent lighting control system automatically switches to dark adaptation mode, precisely controlling the light source intensity and stability, avoiding stray light interference, and meeting the requirements. Specialized testing requires dark environments and specific light sources to ensure accurate data collection by devices such as the fundus camera 222, tonometer, and slit-lamp microscope 242. The corrective equipment and seats in the training area provide targeted pre-treatment training for patients with visual impairments. The intelligent lighting control system switches to a soft lighting mode according to training needs to reduce eye fatigue and synchronously uploads training data to the host server 7 for effect tracking. The comprehensive treatment area is isolated by soft curtains, and examination beds are provided for patients requiring further diagnosis and treatment. Medical staff can access all test data stored on the host server 7 in this area and, combined with the preliminary diagnostic results generated by the AI-assisted diagnostic module 25, provide patients with preliminary treatment, health guidance, or referral suggestions. When specific operations such as visual field timing are activated, the intelligent lighting control system automatically shuts off irrelevant lighting units in the comprehensive treatment area, balancing energy conservation and environmental adaptability. All areas are interconnected with the host server 7 through a unified interface to achieve data sharing and collaborative operation, significantly improving the service capacity and diagnostic efficiency of the large screening vehicle, and adapting to large-scale centralized screening and preliminary diagnosis scenarios.

[0076] Example 5:

[0077] A modularly integrated rapid ophthalmic screening vehicle examination method includes the following steps:

[0078] Step 1, Equipment Adjustment: When an ophthalmological examination is required, the patient enters the screening vehicle body 1 and sits in front of the lifting table 51 of the lifting mechanism 5. The height of the lifting table 51 is adjusted according to the patient's height and examination needs by the electric lifting column 53. The distance sensor 55 can monitor the height of the lifting table 51 in real time.

[0079] Step 2: Constructing the darkroom and adjusting the light: Operate the light-shielding mechanism 3, pull the limiting plate 33 to slide along the limiting groove 32 to unfold the light-shielding cloth 35, use the magnetic plate 34 to fix the position, and cooperate with the light-blocking plate 36 to form an independent darkroom; at the same time, adjust the light-adjusting mechanism 4, and use the drive component 44 to rotate the light-adjusting turntable 45 to switch the filter 46, adjust the light source mode according to the inspection requirements, and jointly construct a standard bright and darkroom inspection environment;

[0080] Step 3, Vision Test: Medical staff operate the automatic refractometer 212 to automatically measure parameters such as the refractive power of the patient's eyes. The vision chart projector 213 projects the vision chart to a suitable position for the patient to undergo a vision test. The contrast sensitivity tester 214 tests the patient's contrast sensitivity. The test data is transmitted to the host server 7 through the interface for preliminary processing and storage.

[0081] Step 4, Fundus and Intraocular Pressure Detection: Next, fundus imaging detection is performed. The fundus camera 222, optical coherence tomography scanner 223, and wide-angle imaging adapter 224 work in sequence to acquire detailed image information of the patient's fundus. The data is transmitted to the host server 7 through the dual interface. Then, intraocular pressure detection is performed. The non-contact tonometer 232 performs the initial measurement. If more accurate data is needed, the contact applanation tonometer 233 can be used for further detection. The detection data is also transmitted to the host server 7 through the dual interface.

[0082] Step 5: Slit-lamp examination and AI diagnosis: Medical staff operate the slit-lamp module 24 and slit-lamp microscope 242 to conduct a detailed examination of the anterior segment of the patient's eye. The digital imaging device 243 records the examination images and transmits them to the host server 7 through dual interfaces. The host server 7 transmits the collected examination data to the AI-assisted diagnosis module 25. The CPU chip 252 and AI computing box 253 quickly analyze and diagnose the data and provide preliminary diagnostic results.

[0083] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
