Description
Technical Field
The utility model belongs to the technical field of cerebral apoplexy rehabilitation device, concretely relates to cerebral apoplexy rehabilitation system is with brain electricity acquisition device that leads less.
Background
With the development and progress of science and technology, the requirements of people on things are changed from old thinking that people can use things as things to be fine and smooth, and only with continuous progress or innovation ideas, a new form is generated to improve the added value of products, so that people can live under the intense examination of market competition.
Learning the action willingness of the patient by acquiring the brain signals of the patient to help the patient to establish an active motor imagery process to complete the expected action is an emerging mode of rehabilitation training of stroke patients in recent years. Different from the traditional rehabilitation training mode, the initiative and the participation of the patient under the assistance of the electroencephalogram equipment in the rehabilitation training process are greatly improved, and the rehabilitation training effect is also greatly improved. The method is characterized in that the vital step is the acquisition of the electroencephalogram signal. At present, the widely used electroencephalogram signal acquisition equipment is an electroencephalogram cap with distributed electroencephalograms of an international 10-20 system. The brain electricity cap is designed by adopting soft flat materials, the electrodes are fixed on the elastic cap according to the international 10-20 brain electrode positioning method and are connected with various brain electricity devices through the adapter cables. The electrode material is a pure silver/silver chloride coating electrode or a silver/silver chloride powder solid electrode, and the general electrodes are classified into dry electrodes, wet electrodes, gel electrodes, saline electrodes and semi-dry electrodes. The most common used are dry and wet electrode brain caps. The dry electrode can be used after being directly worn without other matching materials. Wet electrodes require a dose of conductive paste to be injected between the scalp and the electrode to increase contact and reduce input impedance.
Although the electroencephalogram cap with the distributed electroencephalograms of the international 10-20 system is suitable for a wide range of people (from newborns to adults), the equipment is generally used for dynamic electroencephalogram measurement and 24-72-hour long-range electroencephalogram measurement. However, the rehabilitation training time of the stroke patient generally lasts only several hours, the patient generally carries out single training content within a fixed time period in the training process, and the required dynamic parameters are far less complex than the general dynamic electroencephalogram measurement. In addition, the brain electricity cap with international 10-20 system brain electrode distribution is adopted for the rehabilitation training of the cerebral apoplexy patient, and the following problems are also existed:
1. the electroencephalogram cap needs to be used under the guidance of a professional, and a patient cannot independently complete rehabilitation training. When the electroencephalogram cap is worn, the input electrical impedance of the electrode needs to be adjusted, the work generally needs a professional to adjust the input electrical impedance through a special tool under the matching of test software matched with equipment, the use difficulty is high, and the debugging time is long;
2. the design of the electroencephalogram cap is complex, and the cost of the electroencephalogram system is high. The larger number of the electroencephalogram cap electrodes causes the follow-up electroencephalogram signal processing equipment to need more complex circuits and more signal processing chips, and the cost of the whole electroencephalogram system is increased;
3. the brain electricity cap effect is unstable, and is dressed the degree of difficulty to the apoplexy patient big. Because the number of the electroencephalogram cap electrodes is large, the use effect is greatly influenced by the wearing standard. And due to the particularity of the patient with the apoplexy (hemiplegia, most of the hemiplegic hands and feet are not controlled), the patient can hardly independently wear the existing 10-20 electroencephalogram cap. Even if the electroencephalogram cap is worn with the help of other people, the correct wearing in the using process is difficult to ensure;
4. the brain electricity cap causes a great psychological burden to the patient and is not beneficial to the recovery of the state of an illness. Because the image of the existing electroencephalogram cap is deep in the mind of people, people can think of medical equipment when seeing the similar electroencephalogram cap, the privacy of patients is invisibly exposed, and the psychological burden is added to the patients using the electroencephalogram cap of the international 10-20 system (the patients do not want to throw different eye lights by others to know that the patients are treating).
