Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical devices, and in particular relates to an examination chair suitable for electroencephalogram (EEG). Background Art
[0002] Electroencephalogram (EEG) is a method of checking brain function by amplifying or recording the spontaneous bioelectric potential of the brain from the scalp through an instrument. Every living cell performs biological activities and produces specific waveforms on the EEG, such as α, β, θ, δ and other waves. The physiological and pathological state of the brain is engraved in these complex EEG activities. Electroencephalogram (EEG) is a method of checking brain function by amplifying the spontaneous bioelectricity of the brain and recording it. It is a means of checking brain function that cannot be replaced by CT and MRI examinations. It is scientific, safe and non-invasive. The distribution of brain waves can be intuitively understood by opening the EEG. Usually, the EEG examination requires the examiner to sit and complete the eye-opening and eye-closing, hyperventilation, intermittent flash stimulation and other induced experiments in a relaxed state with eyes closed. The test lasts for 30 minutes, so the cooperation of the examiner and the quality of relaxation directly affect the test results.
[0003] Traditional chairs are relatively simple and cannot provide protection and support for the patient's waist, head and elbows. During the examination, patients are prone to fatigue due to sitting for a long time, which in turn affects the patient's comfort during the examination. Summary of the invention
