Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electroencephalogram measurement, and in particular to a head-worn auxiliary cap used for electroencephalogram measurement of patients with cognitive dysfunction. Background Art
[0002] Cognitive dysfunction is a type of neurological disease that usually affects patients' thinking, memory, attention and comprehension abilities. In recent years, electroencephalogram (EEG) measurements have been widely used in the diagnosis and treatment of cognitive dysfunction. Traditional EEG measurements usually require electrodes to be attached to the patient's scalp and use cumbersome operating procedures to obtain EEG signals. This method usually has problems such as electrode detachment and signal interference, affecting the accuracy and reliability of the data. Existing head-mounted assistive devices usually use an electrode array composed of multiple neural sensors to measure patients' EEG signals in a non-invasive manner, but in actual use, there are still certain problems.
[0003] Existing EEG examinations mostly use an EEG cap for examination, which is worn on the patient's head. Multiple conductive heads are evenly distributed on the EEG cap to monitor and examine the patient. The horizontal distance between each two conductive heads of the existing EEG cap can be adjusted by sliding, but the longitudinal position of the conductive heads is fixed and cannot be adjusted. Due to the different head shapes of patients, the conductive heads cannot be accurately located at the monitoring points on the head of each patient, resulting in inaccurate data. In addition, during long-term monitoring, the existing EEG cap is generally too hard, which makes it very uncomfortable for patients to be monitored while lying flat, affecting the user experience.
[0004] Therefore, a head-worn auxiliary cap for electroencephalogram measurement in patients with cognitive dysfunction is proposed to solve the above problems. Summary of the invention
[0005] The purpose of the present invention is to provide a head-worn auxiliary cap for electroencephalogram measurement of patients with cognitive dysfunction, which solves the above-mentioned technical problems.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a head-worn auxiliary cap for electroencephalogram measurement of patients with cognitive dysfunction, comprising a cap body, wherein the cap body comprises a rear cap piece, a front cap piece and an elastic cap band, wherein the rear cap piece and the front cap piece are fixedly arranged on the outside of the elastic cap band, the rear cap piece and the front cap piece are connected with each other by a zipper, an inner lining strip is fixedly arranged on the top of the elastic cap band, an adjustment strip is slidably installed on the surface of the inner lining strip, and an installation hole is opened through the surface of the adjustment strip.
[0007] Preferably, a tail groove is formed through the surface of the rear cap piece.
[0008] Preferably, the lining strip is located inside the rear cap piece and the front cap piece, a sliding groove is formed through the surface of the lining strip, a limiting groove is formed in the inner wall of the sliding groove, a sliding strip is slidably sleeved inside the limiting groove, the sliding strip is fixed on the surface of the adjustment strip, the adjustment strip is slidably sleeved on the inner wall of the sliding groove, an extension strip is fixed at the end of the adjustment strip, a pull head is fixed at the end of the extension strip away from the adjustment strip, a through groove is formed through the upper and lower parts of the elastic cap girth, the extension strip slides through the inner wall of the through groove, and the pull head is located at the bottom of the elastic cap girth.
[0009] Preferably, Velcro is fixed on the surface of the adjusting strip, and a mother patch of the Velcro is fixed on the surface of the adjusting strip.
[0010] Preferably, a plurality of mounting holes are provided on the surface of the adjustment strip, and the number of the Velcro strips is the same as the number of the mounting holes.
[0011] Preferably, an electrode sheet is inserted into the mounting hole, an electrode wire is fixed to the electrode sheet, and the electrode wire is inserted between the mother sticker and the child sticker of the Velcro.
[0012] Compared with the related art, the head-worn auxiliary cap for electroencephalogram measurement of patients with cognitive dysfunction provided by the present invention has the following beneficial effects:
[0013] The present invention provides a head-worn auxiliary cap for electroencephalogram (EEG) measurement of patients with cognitive dysfunction. The cap is mounted on the patient's head with an elastic cap band, which adapts to the patient's head circumference through its elasticity, thereby ensuring that the cap body can be stably worn on the patient's head. Subsequently, an electrode sheet is inserted into a mounting hole to fit the patient's head, and the electrode wire is fixed by a Velcro, thereby enabling the mounting hole to remain stable on the patient's head and improving monitoring accuracy. After the electrode sheet is placed, the rear cap sheet and the front cap sheet are connected together by a zipper, and the inner lining strip is wrapped and protected, thereby making the patient more comfortable when wearing the cap body for a long time.
[0014] The present invention provides a head-worn auxiliary cap for electroencephalogram (EEG) measurement of patients with cognitive dysfunction. When an electrode sheet is inserted into a mounting hole to perform patch monitoring on the patient, a pull head is pulled to drive an extension belt and an adjustment strip to slide on the inner wall of a through groove, and a slide bar slides on the inner wall of a limiting groove for position limiting, so as to prevent the adjustment strip from being separated from the slide groove and affecting the placement of the electrode sheet, thereby adjusting the position of the electrode sheet inserted in the surface of the mounting hole to meet the standard position of the electrode sheet so as to adapt to the head shapes of different patients.
