Description

Technical Field

[0001] The utility model belongs to the technical field of electroencephalogram sensors, and particularly relates to a pasting structure of an electroencephalogram sensor. Background Art

[0002] Adequate sleep, a balanced diet, and proper exercise are three internationally recognized health standards. However, sleep disorders are generally threatening human health and have become a common problem faced by the whole world. The diagnosis and treatment of sleep disorders rely on accurate sleep monitoring and evaluation.

[0003] Currently, there are psychological scale methods and physiological parameter detection methods for sleep assessment. Among them, the physiological parameter method mainly objectively evaluates sleep quality by monitoring sleep electroencephalogram, electromyogram, electrooculogram, blood oxygen, respiration, body movement, and body position. With the increasing attention and emphasis on sleep quality by people, as well as the development of sleep staging and research methods by scientific researchers, some sleep monitoring products have emerged on the market, such as ZeoCoach, ZeoMobile, JawboneUp, FitbitFlex, Xiaomi smart wearable devices, etc., which are used to monitor the human sleep state and sleep quality in a home environment and have achieved certain effects. However, the problems of accuracy and convenience still limit the wide application of these devices.

[0004] In current sleep monitoring standards, electroencephalogram, electrooculogram, electromyogram, and blood oxygen parameters are the main components for monitoring sleep quality. However, in the process of using existing sleep monitoring devices, a large number of lead wires and sensors need to be connected to the human body to obtain physiological parameters for judging sleep disorders. This monitoring method causes a great sense of restraint to patients with sleep disorders themselves, and because there are many lead wires and sensors, the operation is very cumbersome. Especially, since electroencephalogram signals are relatively weak, if the acquisition electrodes are not pasted well, it is easy to cause a relatively high impedance, which affects the acquisition of electroencephalogram signals and thus affects the accuracy of judgment.

[0005] Chinese Patent No. CN109770899A discloses a mindfulness meditation detection device based on electroencephalogram signals, including a bottom plate. The upper surface of the bottom plate is fixedly connected with a headrest and an electroencephalogram acquisition mechanism. The electroencephalogram acquisition mechanism includes two electric push rods and a limiting block. Both of the two electric push rods and the limiting block are fixedly connected to the upper surface of the bottom plate. A first through hole is formed in the side surface of the limiting block. The limiting block is connected with a transmission shaft through the first through hole in a left-right sliding manner. The left side of the transmission shaft is fixedly connected with an arc-shaped elastic plate. The shaft arm of the transmission shaft is sleeved with a first compression spring, a push-pull block, and a driving plate. The two end parts of the first compression spring are respectively fixedly connected with the arc-shaped elastic plate and the push-pull block.

[0006] The above-mentioned detection device is attached to the head through electrode patches. However, during the attachment process, the spring presses the electrode patch against the human head, exerting a certain pressure on the user's head, thus causing a great sense of restraint to the patient during the detection process. The overall device of the adhesive structure serving the electrode attachment effect is relatively large, not convenient for portable carrying, and unable to effectively change the attachment position.

Detailed implementation manners

[0030] To more clearly illustrate the technical solutions in the embodiments of the present utility model and the prior art, the specific implementation manners of the present utility model will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts, and other implementation manners can also be obtained. Additionally, the terms related to directions only represent the relative positional relationships between components, rather than absolute positional relationships.

[0031] The embodiments of the present utility model provide a paste structure of an electroencephalogram sensor. Please refer to Figures 1 - 7, mainly including a flexible substrate 1, an external connection part 2 provided on the substrate 1, and multiple attaching parts. Hook-and-loop fasteners 5 are built in the attaching parts. Multiple hook-and-loop fasteners 5 are respectively electrically connected to the external connection part 2 through the printed circuit 3 on the substrate 1 and / or through a transfer-type connecting piece; the connecting piece is provided with snap rings 8 for docking and conducting with the hook-and-loop fasteners 5 and / or hook-and-loop fasteners 5; the hook-and-loop fasteners 5 are used for setting attaching electrodes or connecting and conducting with the snap rings 8 on the connecting piece.

[0032] In this application, the pasting structure includes a main structure based on the external connection part 2 and an extended epitaxial structure formed by the connecting piece. The attaching electrodes can be constructed based on the hook-and-loop fasteners 5 on the main structure or the hook-and-loop fasteners 5 at the end of the connecting piece, so as to expand the attaching positions of the attaching electrodes and make them not limited to the periphery of the external connection part 2.

[0033] An attaching adhesive layer can also be provided between the connecting piece and the skin to stably attach the connecting piece to the skin instead of freely hanging down, increasing the load of the attaching part.

[0034] It should be clear that the attaching part is based on the attaching electrode. Under the action of the connecting piece, the attaching part directly / indirectly connected to the external connection part 2 may no longer have a substantial attaching electrode, but is transferred to the position of the hook-and-loop fastener 5 at the end of the connecting piece; that is, the position referred to by the attaching part will change with the use of the connecting piece.

[0035] Exemplarily, when the external connection part 2 docks two attaching parts based on the structure of the substrate 1, the attaching parts include a first attaching part 11 and a second attaching part 12. The first attaching part 11 and the second attaching part 12 are both provided with attaching electrodes based on the hook-and-loop fasteners 5. At this time, the relative positions between the first attaching part 11, the second attaching part 12 and the external connection part 2 can be considered fixed, and the attaching positions are fixed and cannot be reasonably and effectively changed.

[0036] When a connecting piece is used on the first attaching part 11 and / or the second attaching part 12 and an attaching electrode needs to be set based on the hook-and-loop fastener 5 on the connecting piece, the attaching positions of the first attaching part 11 and / or the second attaching part 12 change relative to when the connecting piece is not used. The attaching positions are no longer fixed and can be reasonably and effectively changed. It should be considered that the position where the hook-and-loop fastener 5 on the connecting piece is located is the attaching part.

[0037] In this case, the electrical connection between the hook-and-loop fastener 5 of the attaching part and the external connection part 2 can only be realized through the printed circuit 3 on the substrate 1 and the conducting components on the connecting piece; when the connecting piece is not used, only the printed circuit 3 on the substrate 1 is required; that is, the external connection part 2 is respectively electrically connected to multiple attaching parts through the printed circuit 3 on the substrate 1 or the printed circuit 3 and multiple transfer pieces.

[0038] In this application, the printed circuit 3 is disposed on the flexible substrate 1 and can be deformed to a certain extent accordingly to accommodate the irregularities of the object to be attached.

[0039] Compared with the design rules of the conventional substrate 1, the connection structure between the external connection part 2 and the attachment part is directly connected, and generally there will be no designs such as bending or turning. It has obvious disadvantages in the positional relationship between multiple attachment positions. However, after adopting the connecting piece, this problem can be overcome, and the change of the connection structure has diversity.

[0040] Exemplarily, the external connection part 2 can conductively connect multiple attachment parts, such as the first attachment part 11 and the second attachment part 12 mentioned above. The substrate 1 can be provided with a connection part 13 connected to the substrate structure in the area where the external connection part 2 is located. The substrate structure of the connection part 13 is linear. The external connection part 2 is located at one end of the connection part 13, and the first attachment part 11 and the second attachment part 12 are sequentially connected in series to the connection part 13 starting from the external connection part 2. Among them, the first attachment part 11 is close to the external connection part 2, and the second attachment part 12 is located at the end of the connection part 13. Correspondingly, the substrate structure in the areas where the first attachment part 11 and the second attachment part 12 are located can be enlarged so that it can carry the hook-and-loop 5, the printed circuit 3, etc., and finally form an attachment part including an attachment electrode.

[0041] When more attachment parts are needed, multiple attachment parts can also be sequentially connected in series to the connection part 13 starting from the external connection part 2. The printed circuit 3 is provided in the connection part 13, and multiple attachment parts are conducted to the external connection part 2 through the printed circuit 3.

[0042] Taking the existence of two attachment parts as an example, the design of the printed circuit 3 can be as Figure 2 shown. Among them, the first circuit 31 corresponds to the attachment electrode of the second attachment part 12, and the second circuit 32 corresponds to the attachment electrode of the first attachment part 11; when there are more attachment parts, the circuits can be increased accordingly, but relative independence should be maintained without interference, short circuit and other phenomena. Specifically in implementation, a first conductive cloth 41 can be provided between one pole of the external lead electrode of the first circuit 31 and the external connection part 2, and a second conductive cloth 42 can be provided between the other pole of the external lead electrode of the second circuit 32 and the external connection part 2.

[0043] In the embodiments of this application, both the hook-and-loop 5 and the snap ring 8 can be in a ring structure with the same thickness. The inner diameter of the hook-and-loop 5 is the same as the outer diameter of the snap ring 8, so that when the snap ring 8 is placed inside the hook-and-loop 5, the snap ring 8 is in contact and conductive with the hook-and-loop 5.

[0044] It should be clear that on the connecting piece, the relative positional relationship between the hook 5 and the connecting piece, and between the snap ring 8 and the connecting piece is fixed. However, the docking orientation between the snap ring 8 and the hook 5 on the original attachment part is not fixed and can be docked at relative angles within a certain range, and even can be docked at any relative orientation of 360°. That is, the relative positional relationship between the connecting piece and the original connection structure is changed, and for the newly constructed connection structure, there are real paths such as bending and turning.

[0045] Based on the structure of the connecting piece itself, other requirements can also be achieved, such as an arc-shaped attachment path, a multi-bent attachment path, a spiral attachment path, etc. The connecting piece can be designed according to actual requirements.

[0046] In this application, the construction of the attachment electrode is implemented based on the hook 5. Whether the hook 5 is on the initial attachment part or the connecting piece, the attachment electrode can be constructed.

[0047] In a specific embodiment, the attachment electrode includes a filling layer 6 and an attachment layer 7. The filling layer 6 is placed inside the inner diameter of the hook 5, and the attachment layer 7 covers the outer end face of the hook 5, encapsulating the filling layer 6 inside the hook 5, and the attachment layer 7 is in contact conduction with the hook 5.

[0048] Exemplarily, the attachment layer 7 can be a conductive gel, and the filling layer 6 can be a medical foam, etc. The attachment layer 7 can be pasted and fixed on the outer end face of the hook 5 based on the filling layer 6 and should be in a covering shape to establish a stable contact conduction relationship with the hook 5.

[0049] The filling layer 6 can be a cylindrical gasket, filled inside the inner diameter of the hook 5. Fixing it in a pasting form is convenient for disassembly and reuse, and can support the attachment layer 7 to prevent it from sagging.

[0050] Specifically, the filling layer 6 is used to be pasted and filled inside the inner diameter of the hook 5. The height of the filling layer 6 is at least the same as the thickness of the hook 5. The filling layer 6 is pasted on the inner wall of the hook 5 and the substrate 1 below the hook 5, and the attachment layer 7 is pasted on the exposed end face of the filling layer 6 and the outer end face of the hook 5.

[0051] In this application, the external connection part 2 is internally provided with an external lead electrode, and a connection with an external device is established through the external lead electrode, which can be a communication connection, a data connection, a power connection, etc. Due to the split design concept, the external lead electrode can be led out from the back side of the external connection part 2 so that it falls on the back side of the substrate 1, and the front side of the substrate 1 faces the skin. A fixed-form attachment part can be carried, and the attachment electrode is arranged on the lower side of the attachment part. The attachment part constructed based on the hook 5 on the connecting piece is a movable attachment part.

[0052] In a feasible embodiment, the external lead electrode is electrically connected to the hook 5 of the attachment part; the exposed end of the external lead electrode is arranged on the back side of the external connection part 2, opposite to the orientation of the attachment electrode of the attachment part; a fixing layer 21 for fixedly installing an external device is arranged on the back side of the external connection part 2, and the fixing layer 21 is arranged around or encloses the external lead electrode; a paste layer for attaching to the skin is arranged on the front side of the external connection part 2.

[0053] Exemplarily, the fixing layer 21 can be double-sided tape. The base body 1 is provided with a large through-hole corresponding to the fixing layer 21, so that both the fixing layer 21 and the external lead electrode are exposed. The external device can also be provided with a lead electrode to be docked and electrically connected to the external lead electrode. When bonding based on the fixing layer 21, the electrodes on both sides can be aligned synchronously.

[0054] Exemplarily, the fixing layer 21 can be arranged on the back side of the base body 1. The external lead electrode penetrates through the base body 1. When the external device is located on the back side of the base body 1, its bottom is adhered by the fixing layer 21, and only the electrodes on both sides need to be aligned.

[0055] Meanwhile, the fixing layer 21 can integrally surround the external lead electrode or independently surround each electrode, which can be selected and implemented according to actual needs.

[0056] It can be understood that the paste layer can be an adhesive gel or a conductive gel of the same material as the attachment layer 7, but it does not need to undertake the conductive function; of course, when the spacing requirement of the attachment position is low, the conductive gel on the front side of the external connection part 2 can be directly used as the attachment layer 7 to implement the corresponding function, and only need to be separated into two regions.

[0057] In the embodiment of the present application, the connecting piece is provided with a snap ring 8 and / or a hook 5 for docking and conducting with the hook 5. The connecting piece has various forms of configuration structures and application methods, which are specifically as follows:

[0058] One is a first connecting body that can be independently applied. One end of the first connecting body is a hook 5, and the other end of the connecting piece is a snap ring 8. The snap ring 8 and the hook 5 are respectively arranged on the front and back sides of the first connecting body. As shown in b, when the snap ring 8 of the first connecting body is docked and conducted with the hook 5 of the attachment part, the hook 5 of the first connecting body is in the same orientation as the hook of the attachment part, and the hook 5 of the first connecting body is used to arrange the attachment electrode. Figure 5 As shown in b, when the snap ring 8 of the first connecting body is docked and conducted with the hook 5 of the attachment part, the hook 5 of the first connecting body is in the same orientation as the hook of the attachment part, and the hook 5 of the first connecting body is used to arrange the attachment electrode.

[0059] The second is a second connecting body and a third connecting body used in cooperation. Both ends of the second connecting body are snap rings 8, and the snap rings 8 at both ends are arranged on the same side of the connecting piece. As shown in a, both ends of the third connecting body are hooks 5, and the hooks 5 at both ends are arranged on the same side of the connecting piece. As shown in Figure 5 As shown in a, both ends of the third connecting body are hooks 5, and the hooks 5 at both ends are arranged on the same side of the connecting piece. As shown in Figure 5As shown in c, the clip 8 on one end of the second connector is connected to the hook ring 5 of the attachment part, and the clip 8 on the other end of the second connector is connected to the hook ring 5 on one end of the third connector. The hook ring 5 on the other end of the third connector is used to set the attachment electrode.

[0060] Based on the above three types of connecting pieces, each attachment portion can independently use a connecting piece. When one external portion 2 has multiple attachment portions, some attachment portions can use connecting pieces, while others may not.

[0061] In the present application, the carrier of the connecting piece may also be a flexible substrate 1, and a printed circuit 3 is provided on the carrier so that the ring structures at both ends are directly connected. Figure 5 、 Figure 7 Only the printed circuit 3 of the connecting piece and the ring structures at both ends are shown, and the base 1 is not shown. Figure 6 The printed circuit 3 and the substrate 1 are shown in FIG.

[0062] Specifically, the connecting piece includes a base 1 for carrying the hook ring 5 and / or the snap ring 8. A printed circuit 3 is provided on the base 1 of the connecting piece to connect and conduct the hook rings 5 and / or the snap ring 8 at both ends of the connecting piece.

[0063] The substrate 1 can be made of PET or other flexible materials.

[0064] It is understood that a covering film 22 can be provided to protect the printed circuit 3. This covering film 22 is similar in shape to the main structure's base 1 and can be provided in multiple locations to protect the attachment layer 7, printed circuit 3, or the surface of the base 1. Furthermore, corresponding through-holes can be provided in the covering film 22 without affecting the attachment of the electrodes. Correspondingly, a covering film 22 can also be provided on the connecting piece. An independent covering film 22 can be provided for the fixed layer 21. When in use, the covering film 22 corresponding to the fixed layer 21 can be removed to achieve docking with an external device. The external device can be the host of the EEG sensor, a connection structure, etc.
