Description

Technical Field

[0001] The utility model relates to the technical field of eye strabismus measurement, in particular to a strabismus manual measurement aid. Background Art

[0002] Strabismus refers to the inability of both eyes to look at the target at the same time. It is a common eye disease. Obtaining the accurate degree of strabismus is an important factor affecting the treatment effect. Currently commonly used strabismus measurement methods include: prism plus cover detection method, corneal reflection method, etc.

[0003] After searching, the application with patent publication number CN207613761U discloses a strabismus measurement device, including a frame and a calibration device. The frame is provided with an infrared camera and an infrared LED light. The infrared camera is provided with a narrow-band filter. The measuring device also includes a positioning component, which includes a head-mounted positioning frame. The positioning frame is provided with three detection parts distributed in a triangular shape. The detection parts are reflective sheets or infrared distance sensors. In this way, the accuracy of the strabismus measurement results is improved by adding a narrow-band filter.

[0004] However, due to the setting of the cursor frame, the distance between the cursor frame and the patient is fixed, and the angle is uncertain. Some patients have myopia problems, which leads to unclear observation of the cursor frame and inability to accurately position the cursor frame and the patient, thereby affecting the accuracy of the detection. At the same time, due to the setting of the head fixing device, the height of the patients is different, and the patient's head is placed on the head fixing device, which is prone to shaking, thereby affecting the efficiency of the detection.

[0005] Therefore, we proposed a manual strabismus measurement aid. Utility Model Content

A moving block B16 is slidably connected to the outer wall of the screw rod B15. A two-color lamp 17 is fixedly installed on the left side of the moving block B16. Through the arrangement of the screw rod A9, the screw rod B15 and the two-color lamp 17, after the patient's head is placed on the placement frame 4, the two-color lamp 17 irradiates the patient, and then the cylinder A11 and the screw rod B15 respectively drive the fixed plate 12 and the moving block B16 to move, thereby ensuring that the two-color lamp 17 is facing the patient's eyes. The screw rod A9 can adjust the distance between the two-color lamp 17 and the patient to facilitate the patient's observation, thereby improving the accuracy of the detection.

[0026] Example 2:

[0027] like Figure 2-5 As shown: an electric telescopic rod A3 is fixedly installed on the left side of the top surface of the base 1, and a placement frame 4 of matching specifications is fixedly installed on the top of the electric telescopic rod A3. An electric telescopic rod B5 is fixedly installed on the outer walls of the front and rear sides of the placement frame 4. The telescopic end of the electric telescopic rod B5 is located on the inner wall of the placement frame 4, and a limit plate 6 of matching specifications is fixedly installed on the telescopic end of the electric telescopic rod B5. Through the arrangement of the electric telescopic rod A3, the electric telescopic rod B5 and the limit plate 6, the placement frame 4 is first driven up and down by the electric telescopic rod A3 according to the patient's height, and then the patient places his head on the placement frame 4, and then the electric telescopic rod B5 drives the limit plate 6 to limit and fix the patient's head to prevent the head from shaking, which affects the progress and efficiency of the detection.

[0028] Example 3:

[0029] like Figure 2-3 As shown: the top surface of the base 1 is fixedly mounted with a gantry 18 in a relative position, and the inner walls on the front and rear sides of the gantry 18 are respectively fixedly mounted with cylinders B19 in a relative position, and the output ends of the cylinders B19 are respectively provided with a right baffle 20 and a left baffle 21 of matching specifications, so that the left eye and the right eye can be blocked respectively, thereby detecting the left eye and the right eye respectively.

[0030] The working principle and usage process of the present invention are as follows: when the device is needed to work, the placement frame 4 is first moved up and down by the electric telescopic rod A3 according to the patient's height, and then the patient places his head on the placement frame 4, and then the electric telescopic rod B5 drives the limit plate 6 to limit and fix the patient's head to prevent the head from shaking, which affects the progress and efficiency of the detection. Then the two-color lamp 17 irradiates the patient, and then the cylinder A11 and the screw rod B15 drive the fixed plate 12 and the moving block B16 to move respectively, so as to ensure that the two-color lamp 17 is facing the patient's eyes. The screw rod A9 can adjust the distance between the two-color lamp 17 and the patient, which is convenient for the patient to observe, thereby improving the accuracy of the detection. The patient observes the two-color lamp 17 facing the patient, and the two-color lamp 17 shines on the pupil of the human eye. The detection camera 24 captures the image of the human eye, and then after computer processing, the correspondence between the distance between the corneal light reflection point and the center point of the pupil and the angle of the two-color lamp is calculated, and finally the degree of strabismus is obtained.
