Embodiment Construction

[0032] According to the clinical symptoms of nystagmus caused by vertigo, and vegetative nerve dysfunction caused by vertigo, which leads to spasm of peripheral blood vessels on the face, insufficient blood supply to the end of the face, and insufficient blood supply to the end of the ear. The surface of the nystagmus forms a spot - when the nystagmus spot forms a jumping spot, the jumping spot uses a camera (CCD) to capture the image of the nystagmus, and uses a grating device to distinguish the horizontal amplitude of the nystagmus from the axis of the nystagmus. Vertical amplitude, or For disordered tremor, the grating device is a horizontal grid. When the nystagmus has a horizontal amplitude, the light spot jumps into a horizontal continuous wave map. When the nystagmus has a vertical amplitude, because the grating device is a horizontal grid, the spot jumping continuity is divided into horizontal grids. Breakpoint wave diagram, through CCD signal collection, computer proce...

Abstract

An instrument for synchronously obtaining and analyzing the electronystagmograph associated with dizziness and the ear-peripheral blood flow signal is composed of light-shielding eye mask, micro light source, CCD sensor, raster, infrared light source, infrared detector, signal acquisition card, computer, display and printer.

Description

technical field [0001] The invention relates to a synchronous detection analyzer for a nystagmus graph and an ear peripheral blood flow signal, capable of synchronously detecting the nystagmus graph and the ear peripheral blood flow signal. Background technique [0002] Usually, nystagmus is associated with various physiological changes, such as vertebrobasilar insufficiency, motion sickness, psychiatric disease, especially vertigo disease. Vertigo can not only cause nystagmus, but also cause autonomic dysfunction. Nervous dysfunction can cause peripheral ear blood vessels to constrict, resulting in pale complexion. Since the peripheral blood of the ear is transported by the blood vessels of the face, the pale face during vertigo is caused by insufficient blood supply to the peripheral ear, and the degree of insufficient blood supply to the peripheral ear is necessarily related to the degree of vertigo. Therefore, the degree of vertigo and the cause of vertigo can be analy...
