Abstract

The invention discloses a portable anerythrochloropsia quantitative analyzer, relating to an achromatopsia analyzing instrument. The portable anerythrochloropsia quantitative analyzer only relates to the irritative physical properties and is uncontrolled by the subjective awareness of people. The portable anerythrochloropsia quantitative analyzer is provided with a detecting electrode, a reference electrode, a signal collecting circuit, a signal processing and control module, a keyboard and a color display screen, wherein the detecting electrode is provided with a test electrode and the reference electrode, the signal output end of the test electrode is connected with the signal input end of the signal collecting circuit, the signal output end of the reference electrode is connected with the input end of the signal collecting circuit, the output end of the signal collecting circuit is connected with the input end of the signal processing and control module, the output end of the signal processing and control module is connected with the input end of the color display screen, and the output end of the keyboard is connected with the input end of the signal processing and control module.

Description

technical field [0001] The invention belongs to the field of medical testing equipment, and relates to a color blindness analysis instrument, in particular to a portable red-green color blindness quantitative analyzer. Background technique [0002] Color blindness is a common eye disease, and red-green color blindness is the most common among them. In people's production and life, especially in the fields of transportation, medicine, instrumentation, textiles and fine arts, if various colors cannot be correctly distinguished, it will bring great inconvenience and even cause unnecessary losses. Therefore, color blindness detection is an inspection item in our country's routine physical examination. [0003] At present, my country widely adopts the method of pseudo-same color map for color blindness detection, using the color blindness book as a detection tool, which can only provide qualitative inspection results, and relies on the subjective cognition of the testee for dete...
