Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to an easily detachable EEG cap structure and EEG cap. Background Technology

[0002] Because different regions of the skull produce different signals, EEG caps have multiple electrode sensors. The number of leads refers to how many electrode sensors are on the EEG cap. The more leads there are, the more EEG signals can be detected. The choice of the number of leads usually depends on the specific needs of the research or diagnosis.

[0003] In current EEG caps, the number of electrode sensors in each cap is usually fixed. For example, an 8-channel EEG cap has 8 electrode sensors, and a 10-channel EEG cap has 10 electrode sensors. However, both 8-channel and 10-channel EEG caps are needed for EEG rehabilitation training. Therefore, how to make EEG caps with different numbers of electrodes more efficient has become an urgent problem to be solved. Utility Model Content

[0018] The second cap body is provided with at least one second electrode;

[0019] The second cap body is provided with a connection structure that is connected to the main structure and an electrical connection structure.

The first magnetic block and the second magnetic block attract each other.

[0022] Preferably, the second cap body includes an electrode mounting structure, the second electrode is connected to the electrode mounting structure, and the electrode mounting structure has a left connecting arm and a right connecting arm on both sides respectively.

When the second cap body is connected to the main structure, the supporting slope fits against the outer wall surface of the middle part.

[0023] Preferably, the EEG cap structure has eight first electrodes, and the second cap body has two second electrodes.

[0024] Compared with the prior art, the advantages of this utility model are:

[0025] The EEG cap structure proposed in this invention has expandable mechanical interfaces and electrical signal structures, which can be expanded into an EEG cap with multiple leads or used alone as an EEG cap with fewer leads.

[0031] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0032]

Easy-to-disassemble EEG cap knot

[0033] Understandably, in some studies and diagnoses, such as studies on emotional responses and attention tests, as well as preliminary screenings for diseases such as EEG examinations, epilepsy, and sleep disorders, 8-channel EEG caps are commonly used. In more complex studies and diagnoses, more, such as 10-channel EEG caps, are usually required.

[0034] To improve the utilization rate of EEG caps with fewer leads, combined with Figure 1 As shown, the first aspect of this utility model proposes an easily detachable EEG cap structure, including a main body structure that can be independently worn on the user's head, a first electrode 15, a connecting structure 30, and an electrical connection structure 40.

[0035] Multiple first electrodes 15 are connected to the main structure, and when the main structure is worn on the user's head, each first electrode 15 is in the target position, and the brain electrical activity at the target position of the head can be detected through multiple first electrodes 15.

[0036] Furthermore, the connection structure 30 is connected to the main structure, and the electrical connection structure 40 is connected to the main structure.

[0037] The connection structure 30 is used to connect with the second cap 20 with the second electrode 25, so that the first cap 10 and the second cap 20 are relatively fixed. The electrical connection structure 40 is used to electrically connect with the second cap 20 with the second electrode 25 to obtain the electrical signal of the second electrode 25.

[0038] Thus, this EEG cap structure has interfaces for both mechanical and electrical connections, which is beneficial for expanding the number of electrodes in the future. At the same time, the EEG cap structure can also be used independently with the existing number of electrodes.

[0039] Combination Figure 1 As shown, the main structure includes a middle part 11 and a left extension structure 13 and a right extension structure 12 extending from the middle part 11 to both sides.

[0040] Multiple connecting arms 14 extend upward from the left extension structure 13 and the right extension structure 12, and each connecting arm 14 is provided with at least one first electrode 15.

[0041] Thus, when the main structure is worn on the user's head, the left extension structure 13 and the right extension structure 12 can fit against the sides of the user's skull, and the connecting arm 14 can fit against the contour of the skull, so that the first electrode 15 contacts the user's scalp.

[0042] Understandable. Figure 1 The EEG cap structure shown can be stably worn on the user's head and ensure that multiple first electrodes 15 are in contact with the target area of ​​the scalp, enabling the detection of EEG signals in the target area.

[0043] Furthermore, the connecting arm 14 is constructed as an arc-shaped sheet structure. In particular, the connecting arm 14 is designed to be elastic.

[0044] In this way, the connecting arm 14 can fit the head as closely as possible, so that the first electrode 15 is in close contact with the scalp, and more accurate EEG signals can be obtained.

[0045] In the above embodiment, the left extension structure 13, the right extension structure 12, and the connecting arm 14 located on the left extension structure 13 and the right extension structure 12 are symmetrically distributed on both sides of the skull. That is, the left extension structure 13 and the right extension structure 12 are symmetrical structures to maintain wearing comfort.

[0046] EEG cap

[0047] To maximize resource utilization, EEG caps with fewer leads can be combined with accessories containing individual electrodes to form EEG caps with more leads. Therefore, the second aspect of this invention proposes a technical solution that combines... Figure 3 and Figure 4 As shown, an EEG cap includes:

[0048] The aforementioned easily disassembled EEG cap structure;

[0049] The second cap 20 is provided with at least one second electrode 25;

[0050] The second cap 20 is provided with a connection structure 30 that is connected to the main structure and an electrical connection structure 40.

[0051] Specifically, the electrical connection structure 40 consists of a connector plug 41 and a connector socket 42 that can be plugged into each other. The easily detachable EEG cap structure is provided with a connector plug 41, and the second cap body 20 is provided with a connector socket 42.

[0052] Thus, by combining the easily detachable EEG cap structure (i.e., the first cap 10) and the second cap 20, an EEG cap with more leads can be formed, which can meet different usage needs.

[0053] In an optional embodiment, combined with Figure 3 and Figure 4 As shown, the EEG cap structure has eight first electrodes 15, and the second cap body 20 has two second electrodes 25.

[0054] In an optional embodiment, the connection structure 30 includes a magnetic attraction structure.

[0055] Specifically, the contact surface between the main structure and the second cap 20 is provided with a protruding structure 31, and the contact surface between the second cap 20 and the main structure is provided with a recessed structure 32. The protruding structure 31 can be inserted into the recessed structure 32, and a first magnetic block is provided in the protruding structure 31, and a second magnetic block is provided in the recessed structure 32. The first magnetic block and the second magnetic block attract each other.

[0056] This facilitates the combination and separation of the first cap body 10 and the second cap body 20, making disassembly convenient and quick.

[0057] Combination Figure 2 As shown, the second cap 20 includes an electrode mounting structure 21, and the second electrode 25 is connected to the electrode mounting structure 21. The electrode mounting structure 21 has a left connecting arm 22 and a right connecting arm 23 on both sides. The ends of the left connecting arm 22 and the right connecting arm 23 form a supporting slope 26. When the second cap 20 is connected to the main structure, the supporting slope 26 is in contact with the outer wall of the middle part 11.

[0058] Optionally, the elastic region 24 between the electrode mounting structure 21 and the left connecting arm 22 and the right connecting arm 23 can be adjusted according to the size of the head during wear, so as to better fit the head.

[0059] Understandably, the first cap 10 has a U-shaped structure and the second cap 20 also has a U-shaped structure. By designing this non-closed structure, it is convenient to wear. And through the engagement of the protruding structure 31 and the recessed structure 32, when the first cap 10 and the second cap 20 are attracted together, the first cap 10 and the second cap 20 can deform synchronously.

[0060] In conjunction with the above embodiments, the EEG cap structure proposed in this utility model has expandable mechanical interfaces and electrical signal structures, and can be expanded into an EEG cap with multiple leads or used alone as an EEG cap with fewer leads as needed. Therefore, compared with the EEG caps in the prior art, this EEG cap has a higher utilization rate. At the same time, the combination and connection method of this EEG cap is simpler and more convenient to use.

[0061] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
