Abstract

The invention aims at disclosing an electromyogram evoked potential instrument, which comprises a main controller, a signal processor and an auxiliary controller, wherein the main controller is used for performing various kinds of signal stimulus on the human body; the signal processor is used for collecting, amplifying and filtering on the human body signals; the main controller and the auxiliary controller are connected and perform data interaction; the signal processor is connected with the main controller; the main controller is also connected with a stimulus device and an isolation power supply; the stimulus device is used for regulating the stimulus current intensity, sound intensity and flash intensity through phase change of two groups of pulse signals and supplying the electricity for equipment; and the auxiliary controller is connected with an operator convenient for operating the equipment. Compared with the prior art, the electromyogram evoked potential instrument has the advantages that the electromyogram and the evoked potential are integrated; the industrial integration professional design is used; the dropping-resistant vibration-resistant and temperature-difference-tolerance degrees are high; the anti-electromagnetic interference capability is high; the fault rate is low; the stability is high; the safety is high; the service life is long; and the goal of the invention is achieved.

Description

technical field [0001] The invention relates to a clinical detection instrument, in particular to an electromyography evoked potential instrument which integrates electromyography and evoked electricity. Background technique [0002] Electromyography is an important clinical electrophysiological examination in neurology. It is commonly used in neurology to distinguish the cause of disease and locate the lesion. For the diagnosis of nerve injury, EMG has unique value. In addition, Electromyography is also used to track the recovery process and efficacy of various diseases during the treatment of various diseases. [0003] Evoked potential refers to the specific stimulus given to the nervous system, so that the brain processes the information of the stimulus, and a bioelectrical response that can be detected in the corresponding parts of the system and the brain, has a relatively fixed time interval and a specific phase with the stimulus. [0004] At present, the signal sensi...
