[0002] Neurology is a secondary discipline related to nerves. It does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases (cerebral infarction, cerebral hemorrhage), migraine, brain inflammatory diseases (encephalitis, meningitis), myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy and myasthenia gravis. The main examination methods include head and neck MRI, CT, ECT, PETCT, electroencephalogram, TCD (transcranial Doppler ultrasound), electromyography, evoked potential and blood rheology examination, genetic diagnosis, etc. At the same time, it crosses with the psychology department to diagnose and treat functional diseases such as neurasthenia and insomnia.

[0003] Neurology departments sometimes need to restrain patients' limbs during nursing. During the limb restraint process, the patient's hands or legs need to be restrained. This process is troublesome to operate, and the patient cannot cooperate, which places high demands on the nursing staff. In addition, the existing restraint methods can only restrain the patient's limbs, but cannot restrain the patient's hip position. Therefore, the overall restraint effect needs to be improved.
