DETAILED DESCRIPTION

[0017] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0018] As shown in the figure, an eye detection device integrated with a slit lamp assembly 2 includes a fundus camera 1, a slit lamp assembly 2, a base 4, and a platform 3 for placing the fundus camera 1 and the slit lamp assembly 2. The platform 3 is movably connected to the base 4, and the fundus camera 1 is slidably connected to the platform 3. An arc guide rail 5, a connecting rod 6, and a first motor 8 are arranged on the platform 3 at a position corresponding to the slit lamp assembly 2. A linear guide rail 7 is arranged on the connecting rod 6. The slit lamp assembly 2 passes through the arc guide rail 5 and the linear guide rail 7. The connecting rod 6 is a first motor 8. One end is fixedly connected to the first motor 8, and the other end is arranged corresponding to the position of the arc guide rail 5, and swings along the connecting rod 6 with one end fixed to the first motor 8 as the center of the circle in an arc trajectory, the first motor 8 drives the connecting rod 6 to swing and drives the slit lamp assembly 2 to move along the arc guide rail 5, the slit lamp assembly 2 is arranged at least corresponding to one side of the fundus camera 1, the fundus camera 1 moves close to or away from the position of the human eye, the slit lamp assembly 2 moves in an oblique straight line with the position of the human eye, and the fundus camera 1 and the slit lamp assembly 2 move in a staggered manner.

[0019] The eye detection device is mainly composed of a fundus camera 1, a slit lamp assembly 2, a base 4 and a platform 3. Before using the device, first place the device stably in a suitable detection position; when implementing the scheme, it is necessary to perform an eye test on the patient, and at this time, the power needs to be turned on. Since the platform 3 is movably connected to the base 4, the operator can make a preliminary adjustment to the position of the platform 3 according to the actual position of the patient to ensure that the device as a whole is in a state that is convenient for detection; during the detection, the fundus camera 1 is controlled to move closer to or away from the human eye along the slide rail on the platform 3, so that the fundus camera 1 reaches a suitable shooting position. At the same time, the first motor 8 is started, and the first motor 8 drives the connecting rod 6 to swing. Since one end of the connecting rod 6 is fixed to the first motor 8 and the other end is arranged along the arc guide rail 5, when the connecting rod 6 swings, it drives the slit lamp assembly 2 to move along the arc guide rail 5. Since the slit lamp assembly 2 passes through the linear guide rail 7, during the swinging process of the connecting rod 6, the slit lamp assembly 2 can also be fine-tuned along the linear guide rail 7 to achieve oblique linear movement with the position of the human eye. In this process, the fundus camera 1 and the slit lamp assembly 2 move staggered to avoid interference between the two during the movement. For example, when the fundus camera 1 is detecting the position of the human eye, the fundus camera 1 needs to move closer to or away from the human eye. At this time, the slit lamp assembly 2 will not move to avoid collision with the fundus camera 1. Conversely, when the slit lamp assembly 2 detects the position of the human eye, the fundus camera 1 will not move, and the two are staggered. In this way, the fundus camera 1 can clearly capture the patient's fundus image, and the slit lamp assembly 2 can illuminate the patient's eyes from multiple angles, making it convenient for doctors to observe the eye condition from different angles and obtain more comprehensive eye detection information. The eye detection device of this scheme not only realizes multi-directional detection of the eye through the coordinated operation of various components, but also is easy to operate, and can effectively improve the detection efficiency and accuracy.

[0020] As an improved specific embodiment, an oblique slide 31, at least one slider 32, and a second motor 33 for driving the slider 32 to slide are obliquely arranged on both sides of the platform 3 corresponding to the fundus camera 1. The slider 32 is connected to the oblique slide 31 to drive the arc guide rail 5 to move obliquely towards or away from the human eye position.

[0021] When implementing this solution, an inclined slide 31 is set to cooperate with the slider 32. The slider 32 is driven to slide on the inclined slide 31 by the second motor 33, thereby driving the arc guide rail 5 to move. The operation method is simple, the moving position is diverse, and the position of the human eye can be detected from different angles, which is more flexible.

[0022] As an improved specific embodiment, the second motor 33 is provided with a bevel gear 331, one side of the slider 32 is connected to the arc guide rail 5, and the other side is provided with a bevel rack 321 for engaging with the bevel gear 331. The second motor 33 drives the slider 32 to slide to drive the arc guide rail 5 to move obliquely towards or away from the human eye.

[0023] When the present solution is implemented, it is preferred to use the second motor 33 as the power to drive the bevel gear 331 to cooperate with the bevel rack 321. This structure can make the slide seat slide more smoothly and the sliding speed is uniform. When the present solution is implemented, those skilled in the art can position the bevel rack 321 and the bevel gear 331 by setting guide rails, guide grooves, magnetic attraction, etc. to avoid poor contact between the bevel gear 331 and the bevel rack 321. If no guide grooves or guide rails are set, it is preferred to use magnetic attraction materials to make the bevel gear 331 or the bevel rack 321 so that the two can generate magnetic attraction to each other after contact.

[0024] As an improved specific implementation, the slit lamp assembly 2 is composed of two left slit lamp assemblies 2 arranged on the left side of the fundus camera 1 corresponding to the position of the left eye of the human body, and a right slit lamp assembly 2 arranged on the right side of the fundus camera 1 corresponding to the position of the right eye of the human body. The left slit lamp assembly 2, the right slit lamp assembly 2 and the fundus camera 1 move in an offset manner.

[0025] When this scheme is implemented, the slit lamp assembly 2 arranged on both sides of the fundus camera 1 of this scheme is one on the left and one on the right, and the slit lamp assembly 2 on the left is arranged for detecting the left eye of the human body, and the one on the right is arranged for detecting the right eye of the human body, and the moving position relationship of the fundus lamp and the slit lamp assembly 2 involved in any of the following schemes or improvements is implemented according to the movement method of the fundus lamp and the slit lamp assembly 2 of this scheme, the moving trajectory of the fundus camera 1 is a straight line and is close to or away from the position of the human eye, which is used to adjust the distance between it and the human eye so as to perform fundus imaging in the working position, the moving trajectory of the two slit lamp assemblies 2 is an oblique straight line, and the oblique angle thereof can be adjusted according to the actual inspection requirements to ensure that the best lighting angle and position can be provided for the fundus camera 1 during the inspection process, that is, when the fundus camera 1 is detecting the human eye, the fundus camera 1 moves to a position close to the human eye, at which time the left slit lamp assembly 2 and the right slit lamp assembly 2 cannot be directed toward the part close to the human eye. The fundus camera 1 and the slit lamp assembly 2 are moved to avoid the two meeting each other. On the contrary, when the slit lamp assembly 2 is detecting the position of the human eye, one of the two slit lamp assemblies 2 is close to the human eye position to detect one of the eyes. At this time, the other assembly will not approach the human eye position until the eye being detected completes the detection. For example, when the left slit lamp assembly 2 is detecting the left eye, the right slit lamp assembly 2 will not approach the human eye position until the eye being detected completes the detection. This design makes the fundus camera 1 and the slit lamp assembly 2 not interfere with each other during the movement, and can flexibly adjust the position to meet the needs of different ophthalmic examinations. Through this structural design, the fundus camera 1 and the slit lamp assembly 2 can achieve coordinated movement to improve the efficiency and accuracy of ophthalmic examinations. This solution adopts the arrangement of an oblique slide 31 and a slider 32 for sliding cooperation. When the left / right slit lamp assembly 2 moves, the slider 32 can also move and adjust the position according to actual detection needs.

[0026] As an improved specific implementation, the slit lamp assembly 2 is composed of two left slit lamp assemblies 2 arranged on the left side of the fundus camera 1 corresponding to the position of the left eye of the human body, and a right slit lamp assembly 2 arranged on the right side of the fundus camera 1 corresponding to the position of the right eye of the human body. The left slit lamp assembly 2, the right slit lamp assembly 2 and the fundus camera 1 move in an offset manner.

[0027] When this scheme is implemented, the slit lamp assembly 2 arranged on both sides of the fundus camera 1 of this scheme is one on the left and one on the right, and the slit lamp assembly 2 on the left is arranged for detecting the left eye of the human body, and the one on the right is arranged for detecting the right eye of the human body, and the moving position relationship of the fundus lamp and the slit lamp assembly 2 involved in any of the following schemes or improvements are implemented according to the movement method of the fundus lamp and the slit lamp assembly 2 of this scheme, the moving trajectory of the fundus camera 1 is a straight line and is close to or away from the position of the human eye, which is used to adjust the distance between it and the human eye so as to perform fundus imaging in the working position, and the moving trajectory of the two slit lamp assemblies 2 is an oblique straight line, and the oblique angle thereof can be adjusted according to the actual inspection requirements to ensure that the best lighting angle and position can be provided for the fundus camera 1 during the inspection process, that is, when the fundus camera 1 is detecting the human eye, the fundus camera 1 moves to a position close to the human eye. In this case, the left slit lamp assembly 2 and the right slit lamp assembly 2 cannot move toward the human eye position to avoid the two meeting each other. On the contrary, when the slit lamp assembly 2 is detecting the human eye position, one of the two slit lamp assemblies 2 is close to the human eye position to detect one of the eyes, and the other assembly will not approach the human eye position until the eye being detected completes the detection. For example, when the left slit lamp assembly 2 is detecting the left eye, the right slit lamp assembly 2 will not approach the human eye position until the eye being detected completes the detection. This design allows the fundus camera 1 and the slit lamp assembly 2 to not interfere with each other during movement, and at the same time, the position can be flexibly adjusted to meet the needs of different ophthalmic examinations. Through this structural design, the fundus camera 1 and the slit lamp assembly 2 can achieve coordinated movement to improve the efficiency and accuracy of ophthalmic examinations.

[0028] As an improved specific implementation, a belt 34, a pulley set 35 and a third motor 36 are arranged between the platform 3 and the base 4, the belt 34 is sleeved on the pulley set 35, the belt 34 is connected to the platform 3, and the third motor 36 drives the belt 34 to rotate to drive the platform 3 to move.

[0029] When the present solution is implemented, a third motor 36 is provided to drive the pulley set 35 to rotate so as to drive the belt 34 to rotate. When the belt 34 rotates, the parts fixedly connected to the belt 34 can also cooperate with the belt 34. In the present solution, the belt 34 can drive the platform 3 to move after rotating, and the structure is simple and the movement is convenient.

[0030] As an improved specific implementation, the belt 34 is provided with a fixing block 37 for fixed connection with the platform 3, the fixing block 37 and the platform 3 are fixed by bolts, the belt 34 is placed between the fixing block 37 and the platform 3, and the fixing block 37 and the platform 3 cooperate to clamp the belt 34.

[0031] When implementing this solution, a fixing block 37 and bolts are used to clamp the belt 34. A person skilled in the art can first place the fixing block 37 at a fixed position on the corresponding platform 3, and then position the platform 3 and the fixing block 37 by bolts. At this time, the bolts cannot be fully tightened. The belt 34 needs to be passed between the fixing block 37 and the platform 3 first, and then the fixing block 37 and the bolts are tightened so that the fixing block 37 and the platform 3 can clamp and position the belt 34. The installation method is simple and easy to operate.

[0032] As an improved specific implementation, the arc-shaped guide rail 5 is provided with at least one zero position sensor 51 corresponding to its end position, and the connecting rod 6 can cooperate with the zero position sensor 51 for sensing.

[0033] When implementing the present solution, it is preferred to set a zero position sensor 51, and the zero position sensor 51 is set corresponding to the end position of the arc guide rail 5. When the zero position sensor 51 senses the connecting rod 6, the zero position sensor 51 sends a signal to ensure that the slit lamp assembly 2 can pause moving or accurately return to the initial position. By adopting these structures, the slit lamp assembly 2 can achieve fast and accurate position adjustment in scenarios such as ophthalmic examinations, meet different inspection requirements and stop the movement of the connecting rod 6, which can effectively protect the equipment.

[0034] As an improved specific implementation, the inner walls on both sides of the arc-shaped guide rail 5 in the length direction are arranged at equal distances.

[0035] When implementing this solution, it is preferred to set the distance between the inner walls on both sides of the arc guide rail 5 in the length direction to be equidistant. Such a structure can make the slit lamp move more smoothly in the arc guide rail 5, not easily fall out of the arc guide rail 5, and the connection is more stable.

[0036] As an improved specific embodiment, the slit lamp assembly 2 includes a lamp body 21, an upper top plate 22 arranged at a corresponding upper position of the lamp body 21, and a lower bottom plate 23 arranged at a corresponding lower position of the lamp body 21, a limiting ring 24 for engaging with the arc guide rail 5 is formed between the upper top plate 22 and the lower bottom plate 23, and a plurality of groups of balancing rollers 25 are arranged between the arc guide rail 5 and the limiting ring 24, and the outer peripheral wall of the balancing roller 25 is abutted against the inner peripheral wall of the arc guide rail 5 and can roll along the inner peripheral wall of the arc guide rail 5.

[0037] When the present scheme is implemented, the slit lamp assembly 2 moves along the arc guide rail 5, and the balancing roller 25 rolls on the inner wall of the arc guide rail 5 to ensure that the slit lamp assembly 2 can move smoothly. The design of the limiting ring 24 prevents the slit lamp assembly 2 from shaking up and down during the movement, thereby further improving the stability of the movement. Through this structural design, the slit lamp assembly 2 can achieve precise and smooth movement on the arc guide rail 5. The number of balancing rollers 25 of the present scheme is preferably four, and they are respectively arranged corresponding to the four different directions of the slit lamp to ensure that the slit lamp does not shake when sliding.

[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
