Four-point view detection device with adjustable position

Abstract

The invention provides a four-point view detection device with an adjustable position. The four-point view detection device comprises a body of a four-point view detection instrument, wherein a connecting block is fixedly mounted in the middle of the bottom of the body; the connecting block is movably connected with a cradle head; a fixed seat is arranged right below the cradle head; a strip-shaped groove is formed in the upper side of the fixed seat; a telescopic rod is movably mounted in the strip-shaped groove; the telescopic rod can move forward and backward along the strip-shaped groove;the upper end of the telescopic rod is fixedly connected with the bottom side of the cradle head; a waist type through hole is formed in the bottom of the left side of the telescopic rod; a slide rodis movably mounted in the waist type through hole; and strip-shaped slide grooves which are in bilateral symmetry are formed in the left side and the right side of the strip-shaped groove. The four-point view detection device provided by the invention has the advantages that the structure is simple, the view detection instrument is convenient to fix and disassemble, the height and the angle of theview detection instrument are convenient to adjust so as to adapt to people with different body heights and body types, the view detection device is matched with a lifting chair so as to improve theuse comfort of a user, and the view detection device can be folded, is convenient to carry and store, can meet market demands and is suitable for being popularized.

Description

technical field [0001] The invention belongs to the field of eye detection devices, in particular to a position-adjustable four-point visual field detection device. Background technique [0002] The visual field detection device is a professional ophthalmological instrument used for the measurement of eyeball vision in physiological teaching and the necessary measurement of medical ophthalmic nerves. The visual field test plays a pivotal role in the diagnosis and treatment of ophthalmic diseases. The visual field test is an ophthalmologist. Diagnosis and follow-up of major blinding eye diseases provide important information; there is no doubt that visual field examination is the basic method for diagnosis and monitoring of glaucoma and some other visual and optic nerve diseases, and advanced visual field examination provides early diagnosis and close monitoring of the development of these diseases It provides the possibility and creates conditions for successful treatment; h...

[0002] The visual field detection device is a professional ophthalmological instrument used for the measurement of eyeball vision in physiological teaching and the necessary measurement of medical ophthalmic nerves. The visual field test plays a pivotal role in the diagnosis and treatment of ophthalmic diseases. The visual field test is an ophthalmologist. Diagnosis and follow-up of major blinding eye diseases provide important information; there is no doubt that visual field examination is the basic method for diagnosis and monitoring of glaucoma and some other visual and optic nerve diseases, and advanced visual field examination provides early diagnosis and close monitoring of the development of these diseases It provides the possibility and creates conditions for successful treatment; however, the existing visual field detection devices are generally complex in structure, cumbersome to fix, inconvenient to maintain, large in size, inconvenient to carry and place, and the height and angle of the visual field detection device cannot Adjustment, the detection error is different for people of different heights and shapes, which cannot meet the actual needs, so we need to design a four-point field of view detection device with adjustable positions
