Description
Technical Field
[0001] The utility model relates to the technical field of eye training equipment, in particular to an intelligent device for training the adjustment sensitivity of ophthalmology. Background Technique
[0002] The flipper card is an examination device for adjusting / convergence flexibility in ophthalmic optometry clinical examinations and also a training device for improving flexibility. When in use, a double-sided lens of a certain degree needs to be placed in front of the eyes, and a fixed near visual target is seen clearly through the double-sided lens. Then, the double-sided lens is flipped, and two other lenses of the same degree are placed in front of the eyes, and the near visual target is continued to be observed. Flipping a plus lens and a minus lens once is a cycle, which is the adjustment sensitivity examination. When detecting, we need to record the number of cycles flipped in 1 minute. When the built-in lens is changed to a lens with a base in or out, the same operation steps are the convergence flexibility examination, and the number of cycles flipped in 1 minute also needs to be recorded. Therefore, usually, the doctor not only needs to record the time, but also needs to judge whether the visual target is really seen accurately each time and record the final number of flips. Usually, it is easy to increase the workload of the examiner, and the examinee's mastery of the flipping action often changes from unfamiliar to proficient, which may increase the measurement error caused by unskilled flipping actions during the first examination. When performing the adjustment examination, there is often a monocular measurement.

Then, by pressing the timer reset button 13, the rotation assembly 7 can be controlled by the control main board 12 to operate again, so that the other two opposite ends of the rotation assembly 7 are respectively located at the two mounting holes 10. Then, the other two selected lenses 8 are respectively inserted into the corresponding rotation assembly 7 through the two mounting holes 10. Then, the two blocking assemblies 11 are respectively inserted back into the mounting holes 10, so that the mounting holes 10 can be blocked. When the user needs to perform sensitivity training on the eyes, by holding the handle housing 1, the user can conveniently place the two second through holes 6 in front of both eyes. When the visual target can be seen clearly through the first group of lenses 8, press the timer reset button 13 once.

[0037] Through the battery box 16, it is convenient for medical staff to install the battery, so as to supply power to the device. Then, through the wire holes, it is convenient for the installation of the wire connecting the control main board 12 and the motor 71.
[0038] During operation, before the user needs to perform sensitivity training on the eyes, at this time, the medical staff first selects the lenses 8 with appropriate degrees, and then presses the timer reset button 13. The control main board 12 can control the rotation assembly 7 to operate, so that the two opposite ends of the rotation assembly 7 are respectively located at the two mounting holes 10. Then, the blocking assemblies 11 on the two mounting holes 10 are opened, so as to facilitate inserting the two selected lenses 8 into the corresponding rotation assembly 7 through the two mounting holes 10 respectively. Then, by pressing the timer reset button 13, the control main board 12 can control the rotation assembly 7 to operate again, so that the other two opposite ends of the rotation assembly 7 are respectively located at the two mounting holes 10. Then, the other two selected lenses 8 are respectively inserted into the corresponding rotation assembly 7 through the two mounting holes 10. Then, the two blocking assemblies 11 are respectively inserted back into the mounting holes 10, so as to block the mounting holes 10. When the user needs to perform sensitivity training on the eyes, by holding the handle shell 1, it is convenient for the user to place the two second through holes 6 in front of both eyes. When the user can see the visual target through the first group of lenses 8, press the timer reset button 13 once. The control main board 12 can link the rotation assembly 7 to start, so as to drive the first group of lenses 8 to rotate clockwise by 90°. At this time, the second group of lenses 8 will be exposed in the visual hole, while the first group of lenses 8 will be hidden in the protective shell 3. At the same time, the display screen 14 records the number 1. When the user can see clearly, press the timer reset button 13 again. The rotation assembly 7 starts to rotate counterclockwise by 90 degrees. At this time, the first group of lenses 8 will be exposed in the visual hole, while the second group of lenses 8 will be hidden in the shell. The display screen 14 records the number 2. By manually rotating the shielding assembly 9, any one of the second through holes 6 can be blocked, so as to facilitate the device to perform single-eye training and improve the convenience of device use.
[0039] Through the motor 71 in the rotation assembly 7, it can be fixed in the middle of the inner wall of the protective shell 3 and drive the rotating shaft 72 to rotate. Then, through the rotating shaft 72, the four lens holders 74 can be installed through the cross 73 and driven by the motor 71 to rotate the four lens holders 74 by 90° forward and backward around the rotating shaft 72. Through the lens holders 74, it is convenient for the medical staff to clamp and limit the lenses 8.
[0040] Through the shaft rod 91 in the shielding assembly 9, it can be installed at the center position of the cover 4 through the bearing 92 and install and fix the knob handle 93 and the fixing ring 94. Since the outer wall of the fixing ring 94 is installed with a shielding plate 96 through a connecting rod 95, by rotating the knob handle 93, the shielding plate 96 can be synchronously driven to rotate around the shaft rod 91, so as to enable the shielding plate 96 to block one of the second through holes 6, so as to facilitate the device to perform single-eye training and improve the convenience of device use.
[0041] Through the blocking frame 111 in the blocking component 11, it can not only be inserted into the inner cavity of the mounting hole 10, but also provide a space for opening the buckling groove 112 and the limiting groove 113. And through the buckling groove 112, it is convenient for the staff to buckle out the blocking frame 111 from the mounting hole 10. Then, through the second rubber pad 114 in the limiting groove 113, the friction between the top and bottom of the blocking frame 111 and the bottom of the inner cavity of the mounting hole 10 can be increased, so as to prevent the blocking frame 111 from sliding out of the mounting hole 10.
