Placing type medical eyesight test assisting rack

Abstract

The invention discloses a placement-type medical vision detection auxiliary frame, comprising a main bottom plate, an adjusting sleeve body is hingedly connected to the middle of the main bottom plate, the inner side wall of the adjusting sleeve body is provided with internal threads, and the adjusting stud is screwed on the adjusting sleeve. In the sleeve body, the top end of the adjusting stud protrudes out of the adjusting sleeve body and is fixed with a connecting plate, and support blocks are fixed on both sides of the top surface of the connecting plate. A transverse adjustment motor is fixed on the block, and the output shaft of the transverse adjustment motor is a spline shaft, which is inserted into the spline hole at one end of the transverse adjustment screw, and the moving block is screwed into the transverse adjustment screw. A self-lubricating block is fixed on the bottom surface, and an eye protection baffle is fixed on the upper side wall of the moving block. It can be placed on a table and chair and fixed by bolts, and it can automatically lift to block the eyes without manual support. At the same time, it does not press against the eyes and will not affect the subsequent inspection of the blocked eyes.

Description

Technical field: [0001] The invention relates to the technical field of medical equipment, in particular to a display-type auxiliary frame for medical vision detection. 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 display-type medical vision detection auxiliary frame, which can be placed on tables and chairs and fixed by bolts, which can be automatically lifted to block the eyes witho...
