Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically relates to an electroencephalogram electrode cap. Background Technique

[0002] An electroencephalogram is a graph obtained by amplifying and recording the spontaneous bioelectric potential of the brain from the scalp through a precise electroencephalograph, and it is to record the spontaneous and rhythmic electrical activities of brain cell groups through electrodes. The monitoring methods include conventional electroencephalogram, ambulatory electroencephalogram, and video electroencephalogram. Among them, conventional electroencephalogram usually uses an electroencephalogram cap to wear electrodes. At present, before wearing the current electrode cap, it is necessary to position the electrode patches according to the international 10-20 system, and then cover the cap body of the electrode cap outside the electrode patches. The electrode patches can only be roughly positioned, and the position of the electrode patches will be changed when wearing the cap body of the electrode cap, resulting in inaccurate electroencephalogram detection results; the cap body of the electrode cap generally uses ordinary rubber and silica gel materials. The rubber cap is easy to age, and the silica gel cap has insufficient elasticity. The service life of the electrode cap is short, and the use comfort is low; the strap of the electrode cap generally uses an adjustable buckle for length adjustment, but the operation is relatively cumbersome, which reduces the work efficiency of medical staff.

Preferably, the front-back band 110 and the left-right band 120 are hollow tubular structures made of elastic materials. For example, the front-back band 110 and the left-right band 120 can be medical latex tubes. Medical latex tubes can have a certain elasticity along the tube length direction and can deform in the direction perpendicular to the tube length. Medical latex tubes are often used in medical operations such as infusion, drainage, tracheal intubation, and gastrointestinal imaging. They have no adverse reactions when in contact with the skin, are safe to wear, have higher elasticity, are more resistant to pulling, have good resilience, are not easy to deform, and are resistant to aging. The front-back band 110 extends from the forehead area of the head along the top of the head to the occipital area, and the left-right band 120 extends from the left ear area along the top of the head to the right ear area. Preferably, 3 front-back bands 110 can be provided, and 6 left-right bands 120 can be provided.

[0032] A fixing column 130 is provided at the intersection of the front-back band 110 and the left-right band 120 to fix the intersection position of the front-back band 110 and the left-right band 120. Preferably, the fixing column 130 can include a first column hole 131 and a second column hole 132 which are arranged perpendicular to each other. The intersecting front-back band 110 and left-right band 120 pass through the first column hole 131 and the second column hole 132 respectively. The diameters of the first column hole 131 and the second column hole 132 are smaller than the outer diameters of the front-back band 110 and the left-right band 120 to fix the intersecting front-back band 110 and left-right band 120. Line band fixing plates 140 are provided at both ends of the left-right band 120, and the same-side ends of the left-right band 120 are fixedly connected to the line band fixing plates 140.

The ear hole aligning member 210 is of an L-shaped structure and is fixedly connected to the outside of the line band fixing plate 140. An ear hole plug 211 is fixedly arranged at one end of the ear hole aligning member 210 away from the line band fixing plate 140. The ear hole plug 211 can be inserted into the patient's ear hole to position the ear hole. Preferably, the ear hole plug 211 is made of low-pressure foam material or high-elastic polyester material to adapt to the size of the ear hole when inserted, so that the patient can be more comfortable while accurately positioning the ear hole.

[0034] A nasal root aligning member 220 and an inion aligning member 230 are fixedly arranged in directions perpendicular to the lines connecting the two line band fixing plates 140 at both ends to position the nasal root position and the inion position.

[0035] In this embodiment, the nasal root aligning member 220 includes a first connecting rod 221. The upper end of the first connecting rod 221 is fixedly connected to the front-back band 110. Connecting columns 222 are symmetrically arranged on the inner side of the first connecting rod 221 close to it. A base 223 is arranged on the side of the connecting column 222 away from the first connecting rod 221. A nasal root patch 224 is hingedly arranged on the base 223 to align with the nasal root.

[0036] It can be understood that the nasal root patch 224 can change its angle on the base 223. While the positioning is accurate, it can adapt to the nasal root position shapes of different patients. Anti-slip pads or other materials that increase friction can also be provided on the inner side of the nasal root patch 224.

[0037] In this embodiment, the inion aligner 230 includes a second connecting rod 231. The upper end of the second connecting rod 231 is fixedly connected to the front and rear strap 110.

[0040] When the electroencephalogram electrode cap is in use, first put the electrode cap on the patient's head, insert the earplug 211 into the patient's ear hole, adjust the insertion depth of the earplug 211 to make the patient comfortable, stick the nasal root patch 224 on the patient's nasal root, stick the pillow patch 232 on the inion, tidy up the electrode cap to make the front and rear straps 110 and the left and right straps 120 flat. Then, taking the middle front and rear strap 110 as a reference, position and place the electrode patches. After placing them, pull the first fastener 310 and the second fastener 320 and stick the hook-and-loop fasteners to carry out the electroencephalogram detection work.

[0041] The above-mentioned nasal root is the concave point between the two eyes above the nose; the inion is located at a position slightly lower and in the middle of the back of the head, that is, the back of the head; the ear hole is the opening where the ear communicates with the outside world, located below the auricle (i.e., the outer ear) and close to the side of the head.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
