Technical Field

[0001] The utility model relates to an ophthalmological examination instrument, belonging to the technical field of ophthalmological examination. Background Art

[0002] Slit lamp microscope, as the name implies, is a microscope that illuminates the eye through a slit. Because it is a narrow slit light source, it is called a "light knife". This "light knife" is shone on the eye to form an optical section, and the health status of various parts of the eye can be observed. It is an important instrument indispensable for ophthalmic examination. Slit lamp microscope is usually composed of a lighting system and a binocular microscope. It can not only observe superficial lesions very clearly, but also adjust the focus and the width of the light source to make an "optical section" so that lesions in deep tissues can also be clearly displayed. However, the existing slit lamp microscope has a relatively complex structure, a high cost, and is very inconvenient to wipe and dustproof. The subsequent maintenance is relatively troublesome. Now there is an urgent need for an ophthalmic examination instrument to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-Figure 6 The utility model provides a technical solution: an ophthalmic examination instrument, including a base 1, a foot switch 2, a hydraulic lifting column 3, a top plate 4, a protective box 5, a use end 6, a patient end 7, a forehead support 8 and a mandibular support plate 9. The foot switch 2 is installed on the upper end surface of the base 1, and a top plate 4 is arranged above the base 1. The top plate 4 and the base 1 are connected through the hydraulic lifting column 3. The protective box 5 is installed on the upper end surface of the top plate 4, the use end 6 is arranged on the front end surface of the protective box 5, and the patient end 7 is arranged on the rear end surface of the protective box 5. Forehead supports 8 are fixedly arranged on both sides of the patient end 7, and a mandibular support plate 9 is movably arranged inside the patient end 7. This design solves the problems of complex structure of the original slit lamp microscope and inconvenient wiping and dustproofing.

[0022] As the first embodiment of the utility model: limited sliding columns 11 are arranged at the four corners of the upper end surface of the base 1, and the upper ends of the limited sliding columns 11 are connected to the lower end surface of the top plate 4. The sliding limit columns can play an auxiliary supporting role for the top plate 4 and the base 1, and can also play a certain sliding limit function, so that the top plate 4 can move more stably when rising or falling relative to the base 1 to avoid the influence of equipment shaking. The use end 6 and the patient end 7 are equally rotatably provided with a dustproof door 51. When the equipment is not in use, the dustproof door 51 can be closed to prevent dust. A slit lamp 52 is installed on the top of the protective box 5, a control panel 62 is installed inside the use end 6, a microscope 61 is installed inside the use end 6, a reflector 71 is installed inside the patient end 7, a sliding cavity 93 is opened inside the patient end 7, a drive motor 94 is installed inside the sliding cavity 93, and the input end of the drive motor 94 is connected to the control panel through a wire. 62 output ends are electrically connected, and the control panel 62 can control the opening and closing of the driving motor 94. The left end of the mandibular support plate 9 slides tightly along the inner wall of the sliding cavity 93. A threaded seat 92 is embedded in the left end of the mandibular support plate 9. A threaded rod 95 is clamped on the output end of the driving motor 94. The driving motor 94 can drive the threaded rod 95 to rotate. The threaded rod 95 is meshed with the threaded seat 92. The rotation of the threaded rod 95 can drive the mandibular support plate 9 to move through the threaded seat 92. A cushion 91 is bonded to the upper end surface of the mandibular support plate 9. The cushion 91 is used to support the patient's mandible. A through hole 97 is opened at the right end of the mandibular support plate 9, and a limiting column is set at the right end inside the patient end 7. The limiting column passes through the right end of the mandibular support plate 9 through the through hole 97. The limiting column can play an auxiliary limiting effect on the movement of the mandibular support plate 9. The output end of the foot switch 2 is electrically connected to the input end of the hydraulic lifting column 3 through a wire, and the foot switch 2 is used to control the opening and closing of the hydraulic lifting column 3.

[0023] As the second embodiment of the utility model: after the user opens the dustproof door 51, the patient is first arranged to stand or sit in front of the patient end 7 of the equipment, and then the hydraulic lifting column 3 is controlled to open by the foot switch 2 and drive the top plate 4 to rise or fall relative to the base 1, so as to adjust the patient end 7 to a suitable height. The design of the limit sliding column 11 makes the movement of the top plate 4 more stable. Then the patient's forehead is first placed on the forehead support 8, and then the control panel 62 is used to control the drive motor 94 to start. The drive motor 94 drives the threaded rod 95 to rotate. Since the threaded rod 95 and the threaded seat 92 are engaged with each other, the rotation of the threaded rod 95 drives the mandibular support plate 9 to move in the vertical direction, so as to lift the patient's mandible and make the patient's eyes directly in front of the reflector 71. Then the user comes to the user end 6 and controls the slit lamp 52 to open, and the microscope 61 can be used for observation and analysis. After the observation is completed, the user operates the equipment to reset and close the dustproof door 51, so as to prevent dust from entering and polluting the interior of the equipment, and the external structure of the protective box 5 is simple and convenient for wiping dust.
