Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical equipment, and in particular to a method for manufacturing an electroencephalogram cap. Background Art
[0002] Clinically, EEG testing is a detection technology that records brain electrical activity by appropriately placing electrodes on the head, amplifying the spontaneous bioelectric activity of brain neurons by 1 million times, and converting pulsed direct current into alternating current. It is mainly used to preliminarily determine whether a patient has epileptic-like discharges or to evaluate their brain function. Currently, hospitals generally use products that integrate electrode fixing caps and electrodes. Although this type of EEG cap can avoid the problem of incorrect electrode placement. However, there are still the following disadvantages: 1. Insufficient interference removal ability: When vascular pulsation and ECG interference occur, due to the immobility of the electrodes, it is impossible to adjust the position appropriately to achieve the effect of getting away from the interference source; 2. Lack of operational convenience: The sponge pad support plate of the common EEG cap is fixed on the fixing belt in the form of a slider. Therefore, for patients with different head sizes, the fixing belt needs to be adjusted to match the length of the patient's chin, thereby increasing the overall recording time, and the map may be distorted due to loose fixation; 3. Insufficient head matching: The existing EEG cap has poor elasticity and cannot ensure that each electrode is tightly attached to the scalp or the correct anatomical position, which reduces the accuracy of the EEG; 4. Fast loss: The material of the existing EEG cap body is easily lost due to frequent stretching during operation, resulting in an increase in equipment cost. Therefore, how to develop a new structure of EEG cap and its preparation method to overcome the above-mentioned problems in the prior art is a direction that technicians in this field need to further study.
