Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of detection instruments, and more specifically, to an ophthalmic examination auxiliary device, an ophthalmic examination equipment, and a detection method. Background Art
[0002] Ophthalmic detection equipment usually consists of a head bracket with a large opening and a camera. During the detection, the position of the camera is adjusted so that the camera can be aimed at the eyes of the person being tested, and then the image information of the eyes can be detected. In current ophthalmic detection equipment, the movement of the camera is usually realized by movement adjustment in the three directions of x, y, and z. In theory, the camera can be adjusted to any position. However, in actual equipment, there are limitations on the movement of the three directions of x, y, and z, which affects the movement range of the camera and limits the range of images that the camera can capture. Especially in the z-axis direction, that is, the up and down height direction, due to the large difference in the height of the person being tested, the lifting range of the camera may not be able to fully cover the highest or lowest range, and due to the height limitation of the equipment, the height of the z-axis cannot be further increased, which will affect the scope of application of the equipment and limit the image acquisition range of the camera of the detection equipment.

[0015] The present invention is further configured such that the linkage block is hollow inside and has an inner cavity, and a second through hole communicating with the inner cavity is provided at the lower portion of the linkage block;

[0023] By using angle deflection, the detection module can be adjusted upward or downward at a smaller angle to form a larger deflection range, which can increase the detection range of the detection module as much as possible. Of course, after the detection module is deflected, the shooting angle of the detection module (i.e., the camera) may not be directly aligned with the inspection cloth of the person being inspected, which will cause certain shooting distortion.
[0024] When the detection module rises to a position close to the uppermost side, the side of the detection module facing the head support assembly will deflect and tilt upward, so that the shooting angle of the detection module can continue to tilt upward, so that it can illuminate a higher position, and thus can supplement the travel of the highest point on the upper side of the detection module. When the detection module descends to a position close to the lowermost side, the side of the detection module facing the head support assembly will deflect and tilt downward, so that the shooting angle of the detection module can continue to tilt downward, so that it can illuminate a lower position, and thus can supplement the travel of the lowest point on the lower side of the detection module.

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0035] This embodiment discloses an ophthalmic examination auxiliary device, referring to Figure 1-Figure 8 As shown, the detection component and the head support component, the detection component is the main body of the inspection auxiliary device, mainly using the detection module 10 to shoot the eye condition, obtain eye parameter information, which can be used as a reference for the patient's eye diagnosis. The head support component and the detection component are installed side by side, and the head of the person to be tested can be supported by the head support component so that the head can be stably in an appropriate position for convenient detection.
[0036] Reference Figure 3 , Figure 4 As shown, the detection assembly includes a base 1, a lateral displacement seat 2, a fixed seat 3, a lifting seat 4, a supporting seat 5, a lateral displacement seat 6 and a detection module 10. Among them, the base 1 is located at the bottom of the entire device, and plays a supporting role for the remaining components.
[0037] The traverse seat 1 2 is slidably connected to the base 1, and the sliding direction is the horizontal x direction. Specifically, a guide rail is installed on the base 1, and the drive adjustment is performed through an electric screw structure.
[0038] A fixed seat 3 is fixedly installed on the upper part of the transverse seat 2, and the fixed seat 3 and the transverse seat 2 are supported by four vertical sliding rods. The lifting seat 4 is installed between the transverse seat 2 and the fixed seat 3, and is slidably connected with the sliding rods between the fixed seat 3 and the transverse seat 2, so that the lifting seat 4 can slide and adjust along the vertical z direction, that is, it can be lifted up and down. Specifically, the lifting seat 4 can also be driven and adjusted by an electric screw structure.
[0039] The support seat 5 is located on the upper part of the lifting seat 4 and also on the upper part of the fixing seat 3 . The support seat 5 and the lifting seat 4 are fixedly connected via four vertical rods 12 , so as to support and fix the support seat 5 .
[0040] The second lateral shift seat 6 is mounted on the upper side of the support seat 5 and is slidably connected to the support seat 5, and the sliding direction is the horizontal y direction, the y direction is perpendicular to the x direction, and the x direction, y direction and z direction form three directions that are orthogonally distributed.
[0041] The detection module 10 is installed on the horizontal shifting seat 2 6. The detection module 10 is a visual detection module, generally a shooting device, which can shoot the eyes of the person being detected. A cover 101 is installed outside the detection module 10, which can cover the detection module 10 and other components inside to protect them.
[0042] The head support assembly includes a bracket 7, the lower part of which is fixedly connected to the base 1 and is located at the front of the entire device. The detection module 10 moves along the y direction following the transverse displacement seat 26, so that the distance between the detection module 10 and the head support assembly can be adjusted. A lower head support member 8 is installed in the middle of the bracket 7, and its contour shape fits the chin of the person being tested, so as to support the human head. In addition, the height of the lower head support member 8 can be adjusted. The upper part of the bracket 7 is fixedly connected to an upper head support member 9, which can fit and support the forehead of the human body, thereby facilitating the positioning of the head.
[0043] Reference Figure 4-Figure 8 As shown, the support base 5 includes a fixed plate 51 and a movable plate 52. The support base 5 is a double-layer movable structure. The fixed plate 51 is located at the lower part of the movable plate 52. The fixed plate 51 is fixedly connected to the lifting base 4 to support the entire support base 5.
[0044] The movable plate 52 is located on the upper side of the fixed plate 51 and is rotatably connected via a movable shaft 53. The axis direction of the movable shaft 53 is parallel to the x direction. The movable plate 52 can be deflected and adjusted up and down on the side facing the head support assembly. By adjusting the movable plate 52 up and down on the side facing the head support assembly, the shooting direction of the detection module 10 can be adjusted, and it can be tilted upward or downward.
[0045] When in use, the head of the person being tested is supported by the head support assembly, which can stably support the head in an appropriate position; during testing, the x, y, and z directions are adjusted by adjusting the transverse moving seat 1 2, the transverse moving seat 2 6, and the lifting seat 4, so that the position irradiated by the detection assembly is relative to the position of the eyes of the person being tested, and the eyes of the person being tested can be photographed and tested.
[0046] When the lifting base 4 is adjusted in the vertical z direction, the upper and lower height positions of the detection module 10 are adjusted, which may result in the detection module 10 exceeding the upper and lower limits. Even when the detection module 10 is adjusted to the highest position or the lowest position, the detection module 10 still cannot be aligned with the eyes of the person being detected, resulting in the detection module 10 being unable to perform normal detection.
[0047] Furthermore, by setting the support base 5 as a deflectable and adjustable structure, that is, when the detection module 10 rises to a position close to the uppermost side, the side of the detection module 10 facing the head support assembly will deflect and tilt upward, so that the shooting angle of the detection module 10 can continue to tilt upward, so that it can illuminate a higher position, and thus can supplement the travel of the highest point on the upper side of the detection module 10. When the detection module 10 descends to a position close to the lowermost side, the side of the detection module 10 facing the head support assembly will deflect and tilt downward, so that the shooting angle of the detection module 10 can continue to tilt downward, so that it can illuminate a lower position, and thus can supplement the travel of the lowest point on the lower side of the detection module 10.
[0048] By adopting the deflection structure of the support seat 5, an up and down tilt deflection can be formed. The detection module 10 can be lifted and lowered normally in the middle position of the lifting stroke, and when approaching the extreme position of the up and down stroke, the detection module 10 can produce a small tilt deflection, so that the detection illumination range of the detection module 10 can be larger, thereby increasing the detection range of the detection module 10.
[0049] Specifically, refer to Figure 5 As shown, the movable shaft 53 is located between the fixed plate 51 and the movable plate 52, and a movable gap 54 is formed between the fixed plate 51 and the movable plate 52 for the movable plate 52 to deflect up and down. During the deflection process, the movable plate 52 can reach the limit of travel by abutting against the fixed plate 51.
[0050] The movable shaft 53 is located on the upper side of the fixed plate 51, and a support spring 14 is provided between the fixed plate 51 and the movable plate 52. The support spring 14 can press upward to support the movable plate 52. Specifically, the support spring 14 is located on the side of the movable shaft 53 that is away from the head support assembly; and a receiving groove 511 is provided on the upper side of the fixed plate 51, and the lower side portion of the support spring 14 is embedded in the receiving groove 511 to maintain the structural stability of the support spring 14, so that the support spring 14 can stably apply an upward supporting force to the movable plate 52.
[0051] In addition, a limit rope 16 is provided between the lower side of the movable plate 52 and the lifting seat 4, and the upper and lower ends of the limit rope 16 can limit the travel between the movable plate 52 and the lifting seat 4. The limit rope 16 pulls the movable plate 52 downward to limit the position, and the limit rope 16 and the support spring 14 are used to jointly maintain the balance of the movable plate 52. The movable plate 52 can be pulled downward by the limit rope 16 and supported upward by the support spring 14, so that the movable plate 52 can be maintained in a balanced state.
[0052] Specifically, a through hole 31 for the limiting rope 16 to pass through is opened in the fixing seat 3, and the lower end 162 of the limiting rope 16 is connected to the lifting seat 4, so that the limiting rope 16 can be connected to the lifting seat 4.
[0053] The lower side of the movable plate 52 is fixedly connected with the linkage block 15, and the fixed plate 51 is provided with a clearance hole 512 for the linkage block 15 to pass through. When the support seat 5 follows the lifting seat 4 in the process of descending, the support seat 5 moves downward to the lower side of the stroke, and the linkage block 15 protrudes from the lower side of the movable plate 52, which can abut against the upper side of the fixed seat 3. The linkage block 15 is supported upward, which will push the movable plate 52 to deflect upward, and the other side of the movable plate 52 will deflect downward accordingly, so that the side of the detection module 10 facing the head support component will deflect downward and tilt, and can deflect downward to obtain a lower detection range, refer to Figure 7 shown.
[0054] Reference Figure 7 As shown, during the upward deflection of the right side of the movable plate 52, the distance between the right side position of the movable plate 52 and the lifting seat 4 will gradually expand. At this time, the limit spring 19 in the linkage block 15 will be compressed, and the linkage block 15 will elastically move downward to achieve distance compensation, thereby enabling the movable plate 52 to achieve normal swinging action.
[0055] Reference Figure 5 , Figure 6As shown, the linkage block 15 is located between the movable shaft 53 and the support spring 14. In addition, the linkage block 15 is hollow inside and has an inner cavity 151. A second through hole 152 communicating with the inner cavity 151 is provided at the lower portion of the linkage block 15. A slider 18 is installed in the inner cavity 151. The slider 18 can slide up and down in the inner cavity 151, and the movement of the slider 18 is limited by the inner cavity 151. A limit spring 19 is installed between the slider 18 and the bottom of the inner cavity 151. The limit spring 19 can elastically support the slider 18 upward. The upper end 161 of the limit rope 16 extends into the inner cavity 151 through the second through hole 152 and is connected to the lower side of the slider 18.
[0056] The limiting rope 16 can realize force transmission among the lifting seat 4, the slider 18, the limiting spring 19, the linkage block 15 and the movable plate 52. Under normal conditions, the elastic support of the limiting spring 19 will maintain the state where the slider 18 is in contact with the upper side of the inner cavity 151, that is, under the upward support of the supporting spring 14 on the movable plate 52, the movable plate 52 can be in a normal balanced state. Figure 5 shown.
[0057] Furthermore, the position of the limit rope 16 near the lower end 162 is fixedly connected to the limit block 17, and the limit block 17 is located at the lower side of the fixed seat 3. The size of the limit block 17 is larger than the through hole 131, and a limit can be formed between the fixed seat 3 and the limit block 17. The support seat 5 moves upward to the upper side of the stroke, close to the upper stroke limit position, and the lower side of the fixed seat 3 abuts against the limit block 17, which can overcome the elastic effect of the support spring 14 and drive the limit rope 16 downward to deflect the movable plate 52 downward. For details, refer to Figure 8 When the right side of the movable plate 52 deflects downward, the left side will deflect upward, and correspondingly, the detection direction of the detection module 10 will deflect upward, and it can deflect upward to obtain a higher detection range.
[0058] This embodiment also discloses an ophthalmic testing device, including the ophthalmic testing auxiliary device as described above, as well as a display, a controller and other parts, which can realize the collection of eye image information of the person being tested.
[0059] This embodiment also discloses an ophthalmic detection method, which uses the ophthalmic detection equipment as described above to obtain eye image information of the detected object, and can serve as a basis for diagnosis and treatment.
[0060] 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.
