Vision testing auxiliary frame for ophthalmic medical treatment

Abstract

The invention discloses a vision detection auxiliary frame for ophthalmic medical treatment, which comprises a main base plate, an outer shell is fixed in the middle of the main base plate, a vertical through hole is provided in the middle of the top plate of the outer shell, and a vertical screw is located in the outer shell, vertically The bottom end of the screw rod is hinged on the main base plate, the top of the vertical screw rod protrudes from the vertical through hole, the lower part of the vertical screw rod is fixed with a transmission gear, the main base plate is equipped with a motor frame, and the driving motor is fixed on the top plate of the motor frame. The output shaft of the driving motor passes through the top plate of the motor frame and is fixed with a driving gear, and the driving gear is meshed with the transmission gear; In the threaded hole, the top surface of the top plate of the outer casing is fixed with a guide sleeve, and the lifting rod is inserted into the guide sleeve. It can automatically lift and block the eyes without manual support, it does not press against the eyes, and will not affect the subsequent inspection of the blocked eyes, and will not affect the subsequent detection results.

Description

Technical field: [0001] The invention relates to the technical field of medical equipment, in particular to a vision detection aid frame for ophthalmic medical treatment. Background technique: [0002] When the existing ophthalmology department conducts manual visual acuity detection, a person generally holds a baffle with one hand to block one eye, and uses the other eye to look at the symbols for detection, but it is very troublesome to hold the baffle with one hand, and when testing , the eyes at the occluded place are often pressed very tightly, so that when detecting the previously occluded eyes, the eyes will have a sense of blur, which will affect the detection effect. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide a vision detection auxiliary frame for ophthalmic medical treatment, which can automatically lift and block the eyes without manual hand support. At the same time, it does n...
