Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a diagnostic and therapeutic electroencephalogram cap suitable for all head types. Background Art

[0002] Existing conventional hard EEG caps, such as the technical solutions disclosed in patents (CN218528753U, CN201822854U, CN215534443U) and patent application CN106510699A, have limitations such as fixed head shape, fixed electrode contact sites or narrow adjustment range, fixed model size, and single function. For some patients with congenital developmental defects, head trauma / burn surgery, and abnormal head shape (flat skull, hemiplegia, giant skull). Conventional hard EEG caps cannot meet the above needs, and there are great inconveniences in clinical use. It is often necessary to customize a dedicated EEG cap for a single person. Among patients with abnormal head shape, the probability of having neurological diseases is much higher than that of normal people, and the demand for EEG examinations in this group of patients is also much higher than that of normal people.

[0003] Existing silicone soft EEG caps, such as the technical solutions disclosed in patents (CN220404016U, CN215227721U), can solve the problems of conventional hard EEG caps to a certain extent. For example, for patients whose head shape deviates slightly from the standard head shape, the elastic adaptive deformation of the soft EEG cap can solve the above problems to a certain extent. However, for some patients with irregular head shapes, the elastic tension of silicone in different skin areas is uneven, which often leads to inconsistent adhesion between electrodes in different areas and the scalp, often causing some electrodes to "float" or "poor contact". In addition, the elastic soft EEG cap can adapt to a small range of changes in head shape. It can only be compatible from small to large but not from large to small, and the electrode arrangement spacing cannot be freely adjusted, resulting in the existing soft EEG caps between children and adults still not being adaptable and universal, and patients with a larger degree of head shape abnormality cannot use conventional standard soft EEG caps.

[0100] In the present invention, the free ends of the two mandibular fixing straps 313 are both connected to the second ratchet wire take-up device 34 .

[0101] In the present invention, the shape (covering range) of the second bracket formed by the first soft band, the second soft band and the mandibular fixing band is determined based on the head shape of the target object, and can be changed by the first ratchet wire take-up device 33 and the second ratchet wire take-up device 34 to match the head shape of the target object.

[0102] Preferably, the first soft belt, the second soft belt and the mandibular fixing belt are made of the same material, specifically, they can be made of other soft materials such as silicone, cotton fabric and polyester.

[0104] In the present invention, the number of head circumference adjusting members 32 and head circumference fixing members 13 is the same, and each head circumference fixing member 13 is correspondingly installed with a head circumference adjusting member 32. By rotating the adjusting knob 323 in the head circumference adjusting member, the distance between the skull support 321 and the scalp of the target object can be changed, so that the skull support 321 abuts against the scalp of the target object.

[0107] In the present invention, the positions of the four head circumference adjusting members 32 are determined based on the positions of the four head circumference fixing members 13, specifically: the first head circumference adjusting member is installed at the first end of the two first soft straps 311, the second head circumference adjusting member is installed at the rear position of the two first soft straps 311 close to the first ratchet wire take-up device 33, the third head circumference adjusting member is installed at the front position of the two second soft straps 312, and the fourth head circumference adjusting member is installed at the rear position of the two second soft straps 312.

[0108] It is understandable that since the four head circumference adjusting members 32 are installed at different positions of the first soft belt and the second soft belt, and the first soft belt and the second soft belt are both irregular in shape, the opening position of the positioning hole of the skull support 321 of each head circumference adjusting member 32 may be different.

[0111] When the first ratchet wire take-up device 33 is located in the installation cavity, the first ratchet wire take-up device 33 is in contact with both the first extension rod and the second extension rod of the first extension rod, so that the bonding area is large during bonding and fixing, and the bonding is more stable.

[0112] When the diagnostic EEG cap is in operation, the second ratchet wire take-up device 34 is located at the jaw of the target subject.

[0113] In the present invention, the second bracket 31 is made of soft material, which can better fit the scalp of the target object, and the covering range of the second bracket 31 can be adjusted by the first ratchet wire take-up device 33 and the second ratchet wire take-up device 34, so that it can firmly fit the target object and is suitable for different head shapes.

[0114] Specifically: when the user wears the diagnostic EEG cap on the head of the target object, first pre-tighten the first ratchet wire take-up device 33 and the second ratchet wire take-up device 34 so that the soft belt of the second bracket fits comfortably and tightly against the scalp of the target object; then symmetrically tighten the adjustment knobs 323 of the front, rear, left and right four head circumference adjustment components in sequence so that the four skull supports firmly rest against the corresponding scalp of the target object; finally, adjust the first ratchet wire take-up device 33 and the second ratchet wire take-up device 34 again so that the wearer feels comfortable and the soft support component is firmly fixed to the wearer's head.

[0126] In the present invention, by providing a plurality of the adjusting protrusion pairs 42, the relative positions of the electrode assembly 40 and the electrode orientation adjusting member 22 can be changed, thereby changing the distance between the electrode plug and the scalp of the target object. Specifically, when the adjusting protrusion pair farthest from the ball head handle is installed on the limiting protrusion, the distance between the electrode plug and the scalp of the target object is the largest, and when the adjusting protrusion pair closest to the ball head handle is installed on the limiting protrusion, the distance between the electrode plug and the scalp of the target object is the smallest.

[0127] It should be noted that when changing the relative position of the electrode assembly 40 and the electrode orientation adjustment member 22, it is necessary to first rotate the center rod 41 90 degrees, and then change the length of the electrode rod inserted out of the electrode channel 22A. When adjusted to the appropriate position, the center rod 41 is rotated 90 degrees again, so that the adjustment protrusion pair 42 is stuck in the two limit protrusions.

[0128] The electrode plug 44 includes an electrode rod 441, a top plate 442 fixed to one end of the electrode rod 441 near the ball head handle 43, a limiting column 443 fixed to the middle area of ​​the electrode rod 441, a spring 444 sleeved on the electrode rod 441, and a receiving hole 445 formed by being recessed inward from one end of the electrode rod 441 away from the top plate 442.
