Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a probe mounting assembly, a headgear for acquiring fNIRS data, and a near-infrared brain functional imaging device. Background Technology

[0002] Currently, functional brain imaging technology is widely used in clinical practice and can be used to study the relationship between brain structural damage and brain functional defects, providing an important research tool for understanding the brain structural basis of brain function. In particular, near-infrared brain imaging (fNIRS) utilizes near-infrared light and a multi-channel sensor composed of transmitting and receiving probes to assess brain function based on the neural-blood oxygenation coupling mechanism. FNIRS can penetrate the skull, detect and image changes in brain activity activation with high temporal resolution, and effectively visualize and quantitatively assess brain function. To acquire fNIRS data more accurately, the distance between the transmitting and receiving probes mounted on the headgear must be maintained within a certain range (e.g., 2.5–3.2 cm, preferably 3 cm). The probe spacing cannot be too small. Therefore, how to arrange more probes within the limited headgear size while maintaining the required probe spacing to obtain more comprehensive brain activity information has become a research hotspot in this field.

[0003] To meet the above requirements, existing headgear typically has probe mounting points corresponding to local regions of interest in the brain. Since multiple regions of interest are located in different parts of the brain, the probe positions are relatively scattered, and the number of detection channels cannot meet the requirements. Summary of the Invention

[0004] To address the aforementioned technical problems in the prior art, this disclosure provides a probe mounting assembly, a headgear, and a near-infrared brain functional imaging device. The probe mounting assembly includes: a pad assembly configured to fit the subject's head; and multiple probe mounting portions for mounting probes used to acquire fNIRS data. The pad assembly includes: a pair of first pads, each configured to cover at least the left and right gross motor areas of the subject; multiple probe mounting portions including multiple first pad probe mounting portions distributed along the edges of the first pads and surrounding a central area, with a center-to-center distance between the multiple first pad probe mounting portions within a preset interval; each first pad including: a first edge, a second edge, and a third edge, the first and second edges intersecting at a vertex; and a second pad configured to cover at least the subject's forehead area, with multiple second pad probe mounting portions arranged in at least a row along the lateral direction on the second pad, with a center-to-center distance between the multiple second pad probe mounting portions within a preset interval. The first pad has a first edge adjacent to a second pad, and at least a portion of the plurality of second pad probe mounting portions adjacent to the first edge has a center distance between it and the first pad probe mounting portion located at the first edge, satisfying a preset interval range; a pair of third pads, each configured to at least cover the left and right temporal lobe regions of the subject, the plurality of probe mounting portions including a plurality of third pad probe mounting portions located on the third pads, the center distance between at least a portion of the plurality of third pad probe mounting portions being within a preset interval range, the second edge of the first pad is adjacent to the third pads, and the center distance between the plurality of third pad probe mounting portions adjacent to the second edge and the first pad probe mounting portion located on the second edge satisfying a preset interval range; and a fourth pad, configured to at least cover the occipital lobe region of the subject, the plurality of probe mounting portions including a plurality of fourth pad probe mounting portions arranged in at least one row in the lateral direction on the fourth pad, the center distance between the plurality of fourth pad probe mounting portions being within a preset interval range, the third edge of the first pad being adjacent to the two side ends of the fourth pad. In this way, detection channels can be formed not only between probes installed on each gasket, but also between probes installed on adjacent gaskets. This increases the number of detection channels and provides a wider detection area.

[0005] In the second aspect of this disclosure, a headgear for acquiring fNIRS data is provided, including the probe mounting assembly described in any embodiment and probe adapters for mounting to the respective probe mounting portions of the probe mounting assembly. The probes can be easily mounted and dismounted. This headgear allows the probes to form up to 139+ detection channels, and depending on the fNIRS device, different probe mounting methods can be used, resulting in various detection channel arrangements.

[0006] In the third embodiment of this disclosure, a near-infrared brain functional imaging device is provided, which includes an fNIRS data acquisition module, a cable and a probe. The cable is connected between the fNIRS data acquisition module and the probe. It also includes a headgear for acquiring fNIRS data as described in any embodiment, and a probe adapter mounted on the headgear for adapting the probe. Attached Figure Description

Detailed Implementation

[0023] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application, and that the application can be implemented without one or more of these details. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0024] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other embodiments.

[0025] Reference Figure 1 This application provides a headgear 1 for acquiring fNIRS data. The headgear 1 is worn on the head of a subject to acquire fNIRS data of the brain. The term "head" as used in this application refers to organs above the neck (cervical spine), including the brain region and extracranial tissues such as the skull, skin, and hair. The term "brain" as used in this application refers to the organ remaining after the removal of extracranial tissues, primarily intended to refer to the cerebrum, but not limited to it, and may also include the cerebrum, cerebellum, and brainstem. The term "whole brain" as used in this application is intended to distinguish it from separate brain regions such as the frontal lobe and temporal lobe, but is not limited to all regions of the "brain." "Whole brain" at least includes the frontal lobe, temporal lobe, parietal lobe, and occipital lobe, as well as the various sub-regions under each of the aforementioned brain regions, and in some cases (but not necessarily) may further include other brain regions.

[0026] exist Figure 1 In this illustration, a headgear 1 is placed over a head model 2 to demonstrate the correspondence between the various components of the headgear 1 and the subject's brain. Furthermore, to showcase the internal structure of the headgear 1, it is worn with its inner side folded outwards onto the head model 2. For ease of understanding, this description refers to the positional relationship of the probe mounting components on the inner side of the headgear 1 as shown in the illustration, rather than according to the actual wearing method. However, in actual use… Figure 1 The side facing outwards will face or even be close to the subject's head after the headgear 1 is worn on the subject's head.

[0027] As shown in the figure, the headgear 1 may include a probe mounting assembly. The probe mounting assembly is used to mount a probe, and the headgear 1 is worn on heads of different head shapes, such that the probe mounted on the probe mounting assembly is within a desired distance range to form a desired detection channel. Exemplarily, the probe mounting assembly may include a padding assembly. The padding assembly may be configured to conform to the subject's head (in actual use, not in the figure). Exemplarily, the padding assembly may be processed to have a certain curvature to better conform to the subject's head. Exemplarily, the padding assembly may also be processed to have a certain deformability, but preferably, limited elasticity. The deformability may be achieved by one or more of the following methods: 1. providing a cut in the padding assembly with an opening facing the subject's head; 2. providing an opening through the padding assembly; 3. making a portion of the padding assembly thinner, etc.

[0028] Since the padding assembly needs to conform to the subject's head during use, it can be made of materials with relatively poor thermal conductivity, such as non-metallic materials, to improve wearing comfort. In some embodiments, the padding assembly can be made of materials such as plastic or silicone, which better maintain their shape. In other embodiments, the padding assembly can be formed by a combination of rigid and elastic materials. For example, the padding assembly can be made of a rigid sheet covered with an elastic material such as silicone or rubber. Thus, the padding assembly can maintain a generally unchanged shape in its extension direction while having a certain degree of flexibility or elasticity in its thickness direction. The padding assembly typically has an easy-to-clean surface and is made of skin-friendly material, providing sufficient friction when against the subject's head to prevent displacement during the examination.

[0029] Exemplarily, the probe mounting assembly may further include multiple probe mounting portions. These multiple probe mounting portions are used to mount probes for acquiring fNIRS data. The probe mounting portions can be constructed in any structure, as long as they enable probe assembly. Optionally, all of these probe mounting portions may be located on the padding assembly. Optionally, some of these probe mounting portions may be located on the padding assembly, while others may be located on other carriers of the headcap 1 (e.g., connectors and / or flexible coverings described below). Whether the probe mounting portions are located on the padding assembly or on other carriers of the headcap 1, preferably, these probe mounting portions may have the same or similar structure to accommodate probes with the same or similar structure, achieving probe standardization. Of course, this application does not exclude embodiments where these probe mounting portions have different structures; for example, the probe mounting portions on the padding assembly and the probe mounting portions on other carriers may have different structures. Exemplarily, the probe may be mounted to the probe mounting portion on the outside of the headcap 1. For the probe mounting portion disposed on the pad assembly, exemplarily, the probe can pass through the pad assembly and layers that may be disposed inside the pad assembly, so that the probe can be in close contact with the subject's head to acquire fNIRS data. It should be noted that this application does not exclude the possibility of other layers not passed through by the probe mounting portion being disposed on the inner side of the pad assembly (i.e., the side closer to the subject's head), which preferably allow near-infrared light to pass through in order to acquire fNIRS data.

[0030] Figure 9 An arbitrary portion 910 of a pad assembly according to an exemplary embodiment of this application is shown. This portion 910 of the pad assembly has a probe mounting portion 920. Optionally, a probe 940 can be directly mounted to the probe mounting portion 920. Optionally, a probe adapter 930 can be provided on the probe mounting portion 920. The probe 940 can be mounted to the probe adapter 930, and thus secured to the pad assembly. In some embodiments, the probe mounting portion 920 may include a mounting hole for mounting the probe 940. When the headgear is worn on the subject's head and in place, the axis of the mounting hole may be substantially perpendicular to the corresponding head surface. In other embodiments, the probe mounting portion may include a constraint piece extending along the surface of the pad assembly and secured at both ends to the pad assembly, with a portion of the pad assembly below the constraint piece being hollowed out such that after the probe is mounted within the hollowed-out portion, the outer side of the probe can be limited by the constraint piece. The probe can pass through the hollowed-out portion into the interior of the pad assembly, and the probe cable can extend from the lateral opening of the constraint piece.

[0031] The probe adapter 930, which is mounted to the probe mounting section 920, can be designed to facilitate the installation and removal of the probe 940. For example, the probe adapter 930 may be provided with a snap-fit ​​942. The probe mounting section 920 is provided with a structure that adapts to the snap-fit ​​942, allowing the probe 940 to be detachably mounted to the probe mounting section 920. Probe mounting sections mounted to other carriers of the head cap 1 may also have a similar structure to the probe mounting section 920. For simplicity, further details will not be provided herein.

[0032] Specifically, a pair of probes used to acquire fNIRS data typically includes a transmitting probe and a receiving probe. The transmitting probe emits near-infrared light into the subject's brain. The receiving probe receives the near-infrared light from the transmitting probe, which, after being scattered by the brain, passes through the scalp surface. During fNIRS testing, the distance between the transmitting and receiving probes needs to be maintained within a certain range to form a detection channel between them to obtain valid fNIRS data. A padding assembly helps to stably connect all the probe mounts together, and its rigidity in the extension direction prevents the distance between these probe mounts from being stretched or compressed.

[0033] The liner assembly may include a pair of first liners 110. (See also...) Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 Each pair of first pads is constructed to cover at least the left and right large motor areas of the subject. Figure 3 , Figure 5 and Figure 7 The dashed line OO in the diagram represents the intersection of the sagittal plane and the surface of the head. Figure 2 The first pad 110, which covers the greater motor area of ​​the left brain, is shown. (See diagram.) Figure 2 As shown, the aforementioned probe mounting assembly includes multiple probe mounting portions, which may include multiple first pad probe mounting portions 210 distributed along the edge of the first pad and the central area surrounded by the edge. The center distance between the multiple first pad probe mounting portions is within a preset interval range. The "preset interval range" mentioned here and below can be set according to the condition that the spacing between the probes mounted on the probe mounting portions in question meets the condition for forming a detection channel (e.g., keeping the distance between the transmitting probe and the receiving probe within the range of 2.5 to 3.2 cm).

[0034] It is understandable that there can be various ways to divide brain regions. For example, they can be divided using the common frontal, temporal, occipital, and parietal lobes. Further detailed divisions can be made within these regions, or the Broadman partitioning system can be used. It should be understood that boundaries exist between these brain regions. When the headgear is worn, some probes mounted on it may collect fNIRS data at the boundaries of these brain regions. In this application, "at least covering the subject's left and right greater motor areas" is understood to mean that when the first pad is worn on the subject's head, it should at least cover a portion of the subject's greater motor area. When the probe is mounted at this location, it should be able to acquire at least a portion of the subject's greater motor area's fNIRS data. However, this does not preclude the possibility that probes mounted on the first pad may not be able to collect fNIRS data at the boundaries of the greater motor area or in adjacent peripheral brain regions. The descriptions in the following text such as "able to cover the frontal area of ​​the subject", "able to cover the left and right temporal lobes of the subject", and "able to cover the occipital lobe of the subject" are all the same as the explanation of "at least able to cover the left and right major motor areas of the subject" here, and this application will not repeat them.

[0035] Optionally, to increase the number of detection channels, each first pad probe mounting portion 210 can meet the center-to-center distance requirement within a preset interval range with all adjacent first pad probe mounting portions 210. Thus, regardless of how the transmitter and connector probes are arranged using these first pad probe mounting portions 210 during use, detection channels can be easily formed. For example, every three first pad probe mounting portions 210 can be located substantially at the three vertices of an equilateral triangle. The first pad 110 can act as a skeleton to connect the first pad probe mounting portions 210 at the vertices, thereby ensuring that the center-to-center distance between these first pad probe mounting portions 210 is within the preset interval range even when the cap is worn on the heads of subjects with different head shapes. The center of each triangle can be hollowed out to improve the flexibility of the first pad 110, facilitate a better fit to the subject's head, and enhance wearing comfort. For example, additional openings A can also be provided on the first pad 110 to improve the fit to the subject's head. Opening A can be placed at a location with a relatively large curvature of the head.

[0036] Optionally, the center distance between each first pad probe mounting portion 210 and one or more adjacent first pad probe mounting portions 210 may be within a preset interval range. That is, for any given first pad probe mounting portion 210, not all of its adjacent first pad probe mounting portions can form a center distance that satisfies the preset interval range with the first pad probe mounting portion 210; it is sufficient if only a portion of them do.

[0037] Each first pad 110 may include a first edge 111, a second edge 112, and a third edge 113. The first edge 111 and the second edge 112 intersect at a vertex P. A first pad probe mounting portion 210 is provided on each of the first edge 111, the second edge 112, and the third edge 113. Exemplarily, the first pad 110 may have a generally axisymmetric structure. The axis of symmetry of the first pad 110 (e.g., ...) Figure 2 The dashed line (in the diagram) can pass through vertex P. (Refer to the reference...) Figure 1 and Figure 2 The first edge 111 and the second edge 112 can be located on opposite sides of the axis of symmetry. The first edge 111 is located on the front side of the axis of symmetry, while the second edge 112 is located on the back side of the axis of symmetry. The first edge 111 is closer to the forehead, and the second edge 112 is closer to the subject's ear (temporal lobe area) than the first edge 111. The spacing between the transmitting and receiving probes forming the detection channel and the size of each probe are known. However, it should be understood that when worn on the head, the spacing between the transmitting and receiving probes will change to a certain extent due to the shape and size of the head, but this degree of change is predictable, that is, the degree of change is within the expected range. That is, under this degree of change, a pair of transmitting and receiving probes can still form an effective detection channel. The first pad 110 corresponds to the arrangement of the large movement area. In the illustrated embodiment, each first pad 110 includes 13 first pad probe mounting parts 210. Among them, the ten first pad probe mounting portions 210 connected by the dotted lines are located at the edge of the first pad 110, and the three first pad probe mounting portions 210 located within the area enclosed by the dotted lines are located in the middle area of ​​the first pad 110. Therefore, in Figure 2 In the diagram, the position of the edge of the first pad is indicated by the location of the dashed line. For example, each of the second edge 112 and the first edge 111 is provided with three corresponding first pad probe mounting portions 210. Since the first edge 111 and the second edge 112 intersect at point P, one first pad probe mounting portion 210 is shared at point P. Therefore, it can be determined that the five first pad probe mounting portions 210 on the first pad 110 are located on the first edge 111 and the second edge 112. Figure 2 The shape of the first pad 110 and the arrangement of the first pad probe mounting part shown not only enable the formation of more detection channels for the target area, the large motor area, but also take into account adjacent areas, enabling the formation of more detection channels with the probes on adjacent pads. This allows for more comprehensive and extensive detection of the large motor area and the areas adjacent to it, while increasing the overall number of detection channels to achieve more refined detection of more subdivided brain regions.

[0038] refer to Figure 10Corresponding to the first pad 110 in the large motion area on the left, receiving probes D3, D4, and D5, transmitting probes S10, S9, S8, and S1, receiving probes D9, D10, D11, and D12, and transmitting probes S18 and S2 can be installed. The thick lines represent the detection channels formed between these probes. For example, detection channel 1 is formed between D5 and S1, detection channel 23 is formed between D5 and S8, and detection channels 22, 27, 26, 30, 3, 2, 25, 24, 29, 28, 32, 31, 5, 4, 54, and 53 are also formed, totaling 18 detection channels within the first pad 110. Symmetrically, 18 detection channels can also be formed within the first pad corresponding to the large motion area on the right.

[0039] Reference Figure 1 , Figure 3 and Figure 4 The padding assembly may further include a second pad 120, configured to at least cover the forehead area of ​​the subject. The aforementioned plurality of probe mounting portions may include a plurality of second pad probe mounting portions 220 arranged in at least one row in the lateral direction on the second pad 120. The center-to-center distance between the plurality of second pad probe mounting portions 220 is within a predetermined interval range. The lateral direction refers to the approximate left-right direction when the probe mounting assembly is worn on the subject's head. Figure 3 In the illustrated embodiment, three rows of second padding probe mounting portions 220 are present corresponding to the forehead area. Exemplarily, when multiple rows of second padding probe mounting portions 220 are present, these second padding probe mounting portions 220 may also be aligned along the column direction. Exemplarily, the center distance between these second padding probe mounting portions 220 along both the row and column directions is within a preset interval range. (See reference...) Figure 10 The second liner 120 can be correspondingly equipped with S11, D15, S22, D25, S37 in the top row; S4, D13, S20, D23, S31, D33, S17 in the second row; and D6, S3, D16, S23, D26, S34, D34 in the third row. The thick lines represent the detection channels formed between these probes. For example, detection channel 35 is formed between S11 and D15; detection channel 34 is also formed between S11 and D13; and detection channels 67, 69, 118, 61, 68, 98, 120, 12, 60, 63, 97, 100, 51, 11, 9, 62, 71, 99, 109, 52, 8, 10, 70, 72, 108 and 110 are also formed, for a total of 28 detection channels within the second pad 120.

[0040] Furthermore, the first edge 111 of the first pad is adjacent to the second pad 120. At least a portion of the plurality of second pad probe mounting portions 220 adjacent to the first edge 111 has a center distance from the first pad probe mounting portion 210 located at the first edge 111 that satisfies a preset interval range. (Continuing to refer to...) Figure 10 A detection channel 33 is formed between the transmitting probe S11 of the second pad 120 and the receiving probe D12 on the left first pad 110, and a detection channel 119 is formed between the transmitting probe S37 of the second pad 120 and the receiving probe D32 on the right first pad 110. Those skilled in the art will understand from the description of this application that it is not required that the center distance between each first pad probe mounting portion 210 at the first edge 111 of the first pad and all second pad probe mounting portions 220 of the adjacent second pad meets a preset interval range; conversely, it is not required that the center distance between each second pad probe mounting portion 220 adjacent to the first edge 111 on the second pad and all first pad probe mounting portions 210 at the first edge 111 meets a preset interval range. It is sufficient that at least one of the plurality of first pad probe mounting portions 210 at the first edge 111 has a center distance that meets a preset interval range with one of the second pad probe mounting portions 220. In practice, due to the limited head size, the number of locations where the center distance of the first pad probe mounting portion 210 at the first edge 111 can satisfy a preset interval range with the center distance of the adjacent second pad probe mounting portion 220 is limited. In this document, there are also descriptions of center distances between probe mounting portions on other different pads satisfying the preset interval range, which can also be understood with reference to the above explanation.

[0041] The padding assembly may further include a pair of third pads 130, each configured to cover at least the left and right temporal lobes of the subject. The aforementioned plurality of probe mounting portions may include a plurality of third pad probe mounting portions 230 disposed on the third pads. The center-to-center distance between at least a portion of the plurality of third pad probe mounting portions 230 is within a predetermined interval range. Exemplarily, the plurality of third pad probe mounting portions 230 may also be arranged in rows and / or columns, similar to the second pad probe mounting portions 220.

[0042] Exemplarily, the third pad 130 can be configured to at least correspond to the temporal lobe region above and in front of the subject's ear. Although the ear is not shown in the figure, the area where the ear is located is indicated by reference numeral 3 to facilitate understanding of the principles of this application. (See also...) Figure 1 and Figure 6The third pad 130 may include two triangular pads positioned at the front and back of the ear 3, respectively. The third pad probe mounting portion 230 is positioned at each vertex of the triangular pad. Thus, the third pad 130 may include at least six third pad probe mounting portions 230. This design avoids interference with the ear position and allows the probe mounting portions to surround the ear, completely exposing the ear and improving the patient's comfort. Furthermore, it covers the key area of ​​interest in the temporal lobe and provides a denser channel for acquiring more fNIRS data changes.

[0043] In the illustrated embodiment, a triangular opening is formed in the center of the third pad 130 to improve the fit. In other embodiments not shown, this central opening may have other shapes. Furthermore, openings may also be formed on one or more sides of the triangular pad. Optionally, the third pad 130 may also have a solid structure without any openings. In some embodiments not shown, the third pad may also be constructed to have other shapes.

[0044] Optionally, the first vertices 131 of the two triangular pads of the third pad that are close to each other can be connected. Optionally, the center distance between the two first vertices 131 can be within a preset interval range, thereby allowing the installation of a transmitting probe and a receiving probe at the two first vertices 131 respectively to form a detection channel. Optionally, either a transmitting probe or a receiving probe may be installed at both first vertices 131. In this case, even if the center distance between the two first vertices 131 is within the preset interval range, a detection channel will not be formed. It should be noted that "close to" refers to having a smaller distance relative to other vertices. The connection between the two triangular pads at the first vertices 131 can limit the two parts of the third pad, preventing the distance between them from being too large so that the probes installed on them exceed the detection range of the temporal lobe, and also preventing it from affecting the position of the detection channel formed by the third pad and other adjacent pads. The two triangular pads are allowed to fit against the front and back sides of the subject's ear 3 along with the probe mounting assembly, so that the third pad probe mounting parts 230 have a stable relative positional relationship. Specifically, the two triangular pads are more suitable for the position of the subject's ear 3 compared to other shapes, and can fit the area better when the headgear is worn on the head. This allows the probe mounted on the third pad probe mounting part 230 to fit better on the scalp, so as to obtain more accurate fNIRS data.

[0045] See Figure 10Third pads are provided on the left and right sides of the head. Each third pad may include six third pad probe mounting portions 230. Taking the left third pad as an example, when the probe mounting assembly is in the wearing state, the four upper third pad probe mounting portions 230 are used to mount the transmitting probe, such as S5, S39, S16, and S12 in the figure, and the two lower third pad probe mounting portions 230 are used to mount the receiving probe, such as D1 and D2 in the figure. In this embodiment, each of the two lower third pad probe mounting portions 230 has a center distance from the two of the upper four third pad probe mounting portions 230 to satisfy a preset interval range. Thus, the four transmitting probes and two receiving probes form four detection channels 13, 24, 48, and 36, forming a total of four detection channels within the third pad 130. Symmetrically, four detection channels can also be formed within the third pad 130 corresponding to the right temporal lobe region. In other embodiments, the two lower third pad probe mounting portions 230 can be used to mount transmitting probes, and the upper third pad probe mounting portions 230 can be used to mount receiving probes. In some embodiments, only the middle two of the four upper third pad probe mounting portions 230 have a center distance that meets a preset interval range, for example, the third pad probe mounting portions 230 corresponding to S16 and S39 in the current illustration have a center distance that meets a preset interval range.

[0046] In a preferred embodiment, such as Figure 10 As shown, the uppermost four third pad probe mounting portions 230 may not meet the desired distance, and the center distance between the third pad probe mounting portions 230 corresponding to S12, S16, S5, and S39 may not meet the preset interval range. However, the lower two third pad probe mounting portions 230, namely the third pad probe mounting portions 230 corresponding to D1 and D2, respectively have a center distance that meets the preset interval range with the upper four third pad probe mounting portions 230, namely D1 with the third pad probe mounting portions 230 corresponding to S12 and S16, and D2 with the third pad probe mounting portions 230 corresponding to S5 and S39, thereby forming a maximum of 4 The system provides multiple detection channels. Furthermore, since the four uppermost third pad probe mounting portions 230 may not meet the desired distance, these four third pad probe mounting portions 230 are not limited by the desired distance. This allows them to form more detection channels with probe mounting portions located in the peripheral position (or on adjacent pads) (e.g., the first pad probe mounting portion 210 on the second edge 112 of the first pad 110) (when the desired distance is met). This enables more comprehensive detection of more subdivided brain regions in the temporal lobe and allows for better connection with adjacent brain regions in the temporal lobe to cover more brain regions, thereby achieving detection of more brain regions.

[0047] In some embodiments, the center distance between two adjacent pairs of the four uppermost third pad probe mounting portions 230 all meet a preset interval range.

[0048] The first pad can be located above the third pad. The second edge 112 of the first pad can be adjacent to the third pad. The center distance between the plurality of third pad probe mounting portions 230 adjacent to the second edge 112 and the first pad probe mounting portions 210 located at the second edge 112 meets a preset interval range. Thus, at least one detection channel can be formed between the probe mounting portions of each first pad and the adjacent third pad, thereby detecting the corresponding brain region. Continuing to refer to... Figure 10 Detection channels 37, 49, 50, 125, 126 and 14 are formed between the transmitting probes S12, S16, S39 and S5 of the third pad 130 corresponding to the left temporal lobe area and the receiving probes D3, D4 and D5 on the first pad 110 on the left side, respectively, for a total of 6 detection channels.

[0049] Preferably, the two triangular pads are configured to be arranged in an inverted triangle around the subject's ear. For example... Figure 1 As shown, the flexible covering 500 has an ear opening at the position corresponding to the ear 3 for accommodating the ear 3. The two triangular pads of the third pad can be configured to be arranged in an inverted triangle around the ear opening. Figure 6 As shown, each of the two triangular pads has a first side 134 connecting the first vertex 131 and the third vertex 133, and a second vertex 132 located below the first side 134. The first side 134 of the two triangular pads is arranged side by side with the second edge 112 of the first pad 110.

[0050] For each of the two triangular pads, the probe positioned at the second vertex 132 can form a detection channel with the two probes positioned at the first vertex 131 and the third vertex 133.

[0051] This design allows the probes designed for the temporal lobe region around the ear to be positioned around the ear. This not only avoids the ear protruding from the head surface, but also allows the two inverted triangular pads to better fit the scalp area when worn on the head, creating more detection channels and enabling more comprehensive detection of the temporal lobe region. For example, this design can be used to obtain fNIRS data of the middle temporal gyrus and fusiform gyrus, which are difficult to obtain.

[0052] Therefore, the embodiments provided in this application can not only detect the temporal lobe region above the ear, but also detect the temporal lobe region around the ear, with a wider detection area, which can meet more refined and diversified detection requirements.

[0053] For example, such as Figure 1As shown, the first sides 134 of both triangular pads are located above the ear opening. The projections of the first sides 134 of the two triangular pads onto the plane corresponding to the subject's sagittal plane lie on a predetermined straight line (see...). Figure 6 (The dotted line in the image). When the probe mounting assembly is worn on the subject's head, the angle between the predetermined straight line and the horizontal direction can be less than a preset threshold. Influenced by the shape of the subject's occipital region, for example, in some cases where the area being examined gradually protrudes outwards, the predetermined straight line can be inclined downwards in a front-to-back direction. However, considering the need to cover the temporal lobe region in front of and behind the ear 3, the angle between the predetermined straight line and the horizontal direction should not be too large. Therefore, the preset threshold can be set with reference to ensuring that the two triangular pads can cover the temporal lobe region in front of and behind the ear 3 as much as possible. For example, the preset threshold can be less than or equal to 30 degrees. The second vertices 132 of the two triangular pads can be positioned in front of and behind the ear opening, respectively.

[0054] The human head has a curvature, and after the probe device is worn, the first side 134 can extend along the curvature that generally fits the subject's head.

[0055] In summary, considering the interference from the ear's position, two triangular pads are positioned around the ear, completely exposing it to ensure the wearer's comfort. This design creates sufficient detection channels in key areas of interest, for example, with a preset interval between the probe mounting portions on other pad components described below, forming 6 detection channels, for a total of 12 detection channels. Therefore, the channels are arranged in a triangular pattern, resulting in a denser channel density and the acquisition of more fNIRS data variation information.

[0056] For example, such as Figure 6As shown, the two first vertices 131 can be integrally connected via the connector 400. The sides of the two triangular pads, correspondingly distributed at the front and back positions of the ear, and the connector 400 are configured to avoid the curved edges of the subject's ear. Specifically, when the distance between the two triangular pads increases or the triangular pads rotate, the detection channel formed between some probes may extend beyond the temporal lobe, or may fail to form more detection channels with probes in other areas. Changes in the detection channel may introduce interference, leading to a decrease in data accuracy. Integrating the two first vertices 131 via the connector 400 can at least prevent the two triangular pads from moving away from each other due to the stretching of the flexible cover 500 or the convex shape of the head, thereby affecting the relationship of the detection channel formed with probes in other areas. The connector 400, with sufficient strength, can also prevent the triangular pads from rotating. The triangular pads, with a portion configured to fit the curved edges of the subject's ear, ensure sufficient material strength without applying excessive pressure to the subject's ear, while also having appropriate spacing to form an effective detection channel.

[0057] Exemplarily, the probe mounting assembly is at least capable of acquiring fNIRS data for the middle temporal gyrus and fusiform gyrus. Since at least a portion of the probe can be positioned on one or both sides of the ear, the inventors, through localization analysis of the detection channel formed in this area, discovered that this arrangement allows the formed detection channel to pass through the difficult-to-detect middle temporal gyrus and fusiform gyrus, thereby acquiring fNIRS data in this area. Exemplarily, the third pads are located on both sides of the probe mounting assembly and are symmetrically distributed. For most subjects undergoing testing, the two hemispheres of their brains are symmetrical, thus allowing for simultaneous detection of fNIRS data from both temporal lobes.

[0058] The liner assembly may also include a fourth liner 140, such as Figure 1 , Figure 5 and Figure 8 As shown, the fourth pad is constructed to at least cover the occipital lobe region of the subject. The aforementioned plurality of probe mounting portions may further include a plurality of fourth pad probe mounting portions 240 arranged in at least one row in the transverse direction on the fourth pad. Thus, most of the occipital lobe region can be covered, and it can also maintain union with a pair of third pads in the temporal lobe region. The center-to-center distance between the plurality of fourth pad probe mounting portions is within a preset interval range. Considering the significant variations in head shape in the occipital lobe among different populations, in... Figure 8In the illustrated embodiment, two rows of fourth pad probe mounting portions 240 are provided corresponding to the occipital lobe region. This allows for adaptation to the back of the head of different subjects and coverage of a wider area of ​​the occipital lobe. When the fourth pad 140 is covered externally by a flexible covering 500, it ensures that the fourth pad 140 fits snugly against the back of the subject's head. Exemplarily, when multiple rows of fourth pad probe mounting portions 240 exist, these fourth pad probe mounting portions 240 can also be aligned along the column direction. Exemplarily, the center distance between these fourth pad probe mounting portions 240 along both the row and column directions is within a preset interval range. The third edge 113 of the first pad is adjacent to the two side ends of the fourth pad 140. (See reference...) Figure 10 The fourth pad 140 can be correspondingly equipped with D7, S35, D17, S24, and D27 in the top row; and S6, D14, S21, D24, and S30 in the second row. The thick lines indicate the detection channels formed between these probes. For example, detection channel 17 is formed between S6 and D14; detection channel 16 is also formed between S6 and D7…; detection channels 64, 66, 95, 112, 65, 74, 96, 111, 113, 73, and 75 are also formed, for a total of 13 detection channels within the fourth pad 140.

[0059] For example, such as Figure 1 As shown, the front ends of a pair of third pads 130 are adjacent to the two side ends of the second pad, such that the center distance between the third pad probe mounting portion on the front end of the third pad and at least a portion of the second pad probe mounting portions on the two side ends of the second pad is within a preset interval range. This increases the number of channels on the cap 1. (Continuing to refer to...) Figure 10 A detection channel 15 is formed between the transmitting probe S5 on the front end of the third pad 130 corresponding to the left temporal lobe region and the receiving probe D6 on the left end of the second pad 120; symmetrically, a detection channel 137 is formed between the transmitting probe S43 on the front end of the third pad 130 corresponding to the right temporal lobe region and the receiving probe D34 on the right end of the second pad 120.

[0060] For example, the rear ends of a pair of third pads are respectively adjacent to the two side ends of a fourth pad, such that the center distance between the third pad probe mounting portion on the rear ends of the pair of third pads and at least a portion of the fourth pad probe mounting portions on the two side ends of the fourth pad is within the preset interval range. This increases the number of detection channels on the headgear 1, covering more subdivided brain regions, especially the boundary between the temporal and occipital lobes. (Continuing to refer to...) Figure 10A detection channel 38 is formed between the transmitting probe S12 on the rear end of the third pad 130 corresponding to the left temporal lobe region and the receiving probe D7 on the left end of the fourth pad 140; symmetrically, a detection channel 42 is formed between the transmitting probe S14 on the rear end of the third pad 130 corresponding to the right temporal lobe region and the receiving probe D27 on the right end of the fourth pad 140.

[0061] Therefore, a pair of first pads 110 cover the corresponding brain regions on the top of the head. Below the pair of first pads, a second pad, a pair of third pads, and a fourth pad surround the entire head, forming complete coverage of the corresponding brain regions. In this way, detection channels can be formed not only between the probes mounted on each pad, but also between the probes mounted on adjacent pads. This increases the number of detection channels, covering more subdivided brain regions, especially at the boundaries between brain regions.

[0062] The aforementioned padding components can be independent of each other and secured to the subject's head during testing via structures such as hairpins. In some embodiments, multiple padding components can be interconnected to maintain relative positions when worn on the subject's head. It is important to note that the edges of the padding components are not directly connected to adjacent padding components. As shown in the figure, taking the first and second pads as examples, the first and second pads are not integral; the edges of the first and second pads are spaced apart. In the case where the edges of the first and second pads are spaced apart, optionally, this gap can be connected by a structure relatively thinner than the padding components. Optionally, this gap can expose the subject's head. Optionally, this gap exposes a layer disposed beneath the padding components. In summary, the edges of adjacent pads are not connected by a large area of ​​padding components.

[0063] In some embodiments, multiple padding assemblies are disposed on the inner or outer surface of an elastic headgear, which covers the subject's head and attaches the multiple padding assemblies to the subject's head surface.

[0064] Therefore, the embodiments of this application, by providing a large number of probe mounting portions on the pad assembly corresponding to each brain functional area, and ensuring that the center distance between these probe mounting portions meets a preset interval range, can form multiple detection channels after installing probes on each pad. Furthermore, by adopting the method provided in the embodiments of this application, at least a portion of adjacent but not connected pads are positioned close to each other, and by constructing the shape, arrangement, and method of the pads corresponding to each brain area, the center distance between the probe mounting portions on at least some of the close-to-each-other pads, belonging to different pads, meets a preset interval range within a limited head size. This allows detection channels to be formed in the gaps between adjacent pads, increasing the number of detection channels that can be formed on the probe mounting assembly. The separated pads can better conform to the subject's head surface, avoiding uneven pressure and bulging during wear, improving detection comfort and accuracy.

[0065] Exemplarily, the probe mounting assembly may also include an integral flexible cover 500 that covers the outside of the padding assembly. The flexible cover 500 may comprise various types of elastic fabrics, such as nylon, spandex, or yarns composed of two or more of these materials. In some embodiments, the flexible cover 500 may also be made of silicone and may have a thickness less than that of the padding assembly. The flexible cover 500 has better elasticity than the padding assembly, allowing the padding assembly to be firmly pressed against the subject's head after the subject wears the probe mounting assembly. Its relatively small thickness prevents bulging under pressure. In some embodiments, the padding assembly is not glued to the flexible cover 500 but is only partially connected and secured to each other. For example, the flexible cover 500 and the padding assembly are connected to each other via a mounting portion described below. When the flexible cover 500 is stretched, the unsecured portions of its surface may slide relative to the surface of the padding assembly. This effectively avoids discomfort to the examinee and excessive wrinkling caused by uneven force distribution on the flexible cover 500. In this embodiment, the flexible cover 500 is positioned on the side of the padding assembly away from the examinee's head and configured to cover the padding assembly, allowing for more even application of elasticity to the padding assembly, enabling it to better conform to the examinee's head. Optionally, in some embodiments, the padding assembly may include multiple independent pads, in which case the flexible cover 500 can hold the multiple pads together. Furthermore, the flexible cover 500 can help position the padding assembly at the desired location on the head. For example, the instruction manual for this headgear product can provide detailed instructions on the wearing position of the probe mounting assembly. For example, the forehead edge may be positioned at eyebrow level or a few centimeters above the eyebrow. Exemplarily, the flexible cover 500 may include a fastener to maintain the relative position of the probe mounting assembly to the examinee's head for an extended period. The fastener may include a buckle, Velcro, or any other component that facilitates fastening.

[0066] Exemplarily, multiple probe mounting portions may be exposed outside the flexible cover 500. As described above, exemplarily, the probe may be mounted to the probe mounting portion outside the head cap 1. Exemplarily, the probe may be in contact with the subject's head through the head cap 1 so that the probe can be in close contact with the subject's head to acquire fNIRS data.

[0067] Exemplarily, each first pad 110 may also include a fourth edge 114, such as Figure 1 and Figure 2As shown, the fourth edge 114 is positioned opposite to the third edge 113. The fact that the fourth edge 114 and the third edge 113 are opposite does not mean that they must be parallel; embodiments of this application allow for a certain angle between the fourth edge 114 and the third edge 113. The fourth edge 114 and the third edge 113 are located on opposite sides of the first pad 110. Exemplarily, when the first pad 110 has an axisymmetric structure, the fourth edge 114 and the third edge 113 can be symmetrically positioned about the axis of symmetry. The fourth edge 114 intersects the first edge 111 at a point, and the fourth edge 114 can extend obliquely backward toward the sagittal plane of the brain from that point. Thus, as... Figure 3 and Figure 7 As shown, the fourth edges of a pair of first pads 110 can be joined with the second pad to form a first intersection region 310. A second intersection region 320 can be formed between the pair of first pads 110.

[0068] The aforementioned plurality of probe mounting portions may further include an independent probe mounting portion 261 disposed within a first intersection region 310 jointly surrounded by the fourth edge 114 of the first pad 110 and the second pad 120. The distance between the independent probe mounting portion 261 and the adjacent second pad probe mounting portion 220 on the second pad 120 and the first pad probe mounting portion 210 on the fourth edge 114 meets a preset interval range. Thus, after the probe is mounted to these probe mounting portions, a detection channel can be formed around the first intersection region.

[0069] Normally, the human skull is highest near the CZ point. If the padding covers the CZ point, the force within it will not be distributed, causing the padding around the CZ point to bulge. This also leads to a bulge when the probe is installed in the probe mounting area, affecting wearing comfort and preventing the probe from contacting the scalp, thus hindering the acquisition of fNIRS data. To address this, the force is distributed from the highest point to the intersection areas between different pads, such as a second intersection area 320 formed by a pair of first pads 110 spaced apart on either side of the CZ point, and a first intersection area 310 formed by a pair of first pads 110 spaced apart from the second pad. Independent probe mounting parts 261 are placed in these intersection areas. This allows the headgear 1 to fit the scalp more closely, enabling the probes in these areas to obtain accurate fNIRS data. For these intersection areas, the spacing of the probe adapters within the intersection areas can be controlled by the elasticity of the flexible cover 500.

[0070] As previously mentioned, if one or both of the first or second pads extend into the intersection area, the extended portion may have a significant degree of curvature, causing the first and / or second pads to not conform well to the subject's head surface, resulting in bulges. Providing an independent probe mounting section 261 can prevent this from happening. There can be one or more independent probe mounting sections. When there is only one independent probe mounting section, after the probe is installed, it can form a detection channel with the corresponding probe on the first pad and simultaneously with the corresponding probe on the second pad. For example, if a receiving probe is installed in the independent probe mounting section, the transmitting probe installed in the first pad probe mounting section and the transmitting probe installed in the second pad probe mounting section can simultaneously form a detection channel with the receiving probe positioned between them. When there are multiple independent probe mounting sections, at least one probe in each of the multiple independent probe mounting sections can form a detection channel with the corresponding probe on the first pad, and at least one probe in each of the multiple independent probe mounting sections can also form a detection channel with the corresponding probe on the second pad. These two detection channels can correspond to probes installed in one or two independent probe mounting sections.

[0071] For example, in Figure 10 In the illustrated embodiment, there are two independent probe mounting portions 261 within the first intersection region 310, arranged laterally. Since a pair of first pads are symmetrically arranged, the first intersection region 310 is also symmetrically divided into two halves. Each half of the first intersection region 310 contains one independent probe mounting portion 261, one corresponding to S19 in the figure and the other to S32. S19 forms a detection channel 57 with the receiving probe D12 on the first pad 110 corresponding to the left large motion area, and also forms a detection channel 58 with the receiving probe D15 on the second pad 120; symmetrically, S32 forms a detection channel 103 with the receiving probe D32 on the first pad 110 corresponding to the right large motion area, and also forms a detection channel 102 with the receiving probe D25 on the second pad 120.

[0072] Considering that the overall arrangement of the probes can adapt to the orientation of the EEG points, and considering the intersection area that needs to be combined with the second pad 120 corresponding to the frontal lobe area and the pair of first pads 110 corresponding to the left and right major motor areas, the probe mounting assembly may, exemplarily, also include a fifth pad 150, such as... Figure 5As shown. The fifth pad 150 may be located between a pair of first pads 110, and the fifth pad 150 is configured to at least cover the parietal lobe region of the subject. Multiple probe mounting portions may include multiple fifth pad probe mounting portions 250 distributed along the edges of the fifth pad 150 and the central area surrounded by the edges. The center-to-center distance between the individual fifth pad probe mounting portions is within a predetermined interval. After probes are mounted on these fifth pad probe mounting portions 250, a sufficient number of detection channels can be formed. In the illustrated embodiment, the fifth pad 150 is hexagonal. A fifth pad probe mounting portion 250 is provided at each vertex of the hexagon. Furthermore, a fifth pad probe mounting portion 250 is also provided at the center of the hexagon.

[0073] Reference Figure 10 The fifth pad 150 corresponding to the top leaf region can be equipped with transmitting probes S41 and S7, receiving probes D18, D19 and D20, and transmitting probes S26 and S27. The thick lines indicate the detection channels formed between these probes. For example, detection channel 132 is formed between S41 and D18, detection channel 133 is formed between S41 and D19, and so on. Detection channels 20, 21, 79, 80, 83 and 84 are also formed, for a total of eight detection channels within the first pad 110.

[0074] For example, such as Figure 5 As shown, the center distance between the fifth pad probe mounting portion on the edge of the fifth pad 150 and the adjacent first pad probe mounting portion on the first pad 110 is within a preset interval range. This allows for an increase in the number of channels on the cap 1. (Continuing to refer to...) Figure 10 The receiving probe D20 at the foremost point of the fifth pad 150 forms detection channels 55 and 87 with the transmitting probes S18 and S28 on the first pads 110 on the left and right sides, respectively. The transmitting probes S41 and S7 on the left side of the fifth pad 150 form detection channels 19, 18, and 131 with the receiving probes D9 and D10. The transmitting probes S26 and S27 on the right side of the fifth pad 150 form detection channels 86, 85, and 82 with the receiving probes D29 and D30.

[0075] The arrangement of the probe mounting parts on the first, second, third, fourth, and fifth pads on the cap can be roughly consistent with the direction of the EEG points (10-20 electrode lead positions). This makes it easy to identify the probe mounting parts, thus facilitating the operator to install the probes onto the corresponding probe adapters.

[0076] For example, the edge of each first pad 110 may have a recess 119, such as Figure 1 , 2As shown in Figure 7, for each first pad, a recess 119 is located on both sides of the first pad opposite to the apex P, and the recess 119 of the first pad is provided along the edge of the fifth pad 150. This allows for more accurate coverage of the large motion area. Furthermore, the fifth pad 150 can be avoided, and a detection channel can be formed in the avoidance area to detect the boundary between the large motion area and the parietal lobe area.

[0077] Exemplarily, each first pad 110 may further include a sixth edge 116, a seventh edge 117, and an eighth edge 118 sequentially connected to the fifth edge 115. The eighth edge 118 is connected to the third edge 113. For each first pad 110, the fifth edge 115 and the eighth edge 118 are disposed opposite each other, and the sixth edge 116 and the seventh edge 117 are bent inward relative to the fifth edge 115 and the eighth edge 118, respectively, to form a recess 119. Exemplarily, each first pad 110 may be an axisymmetric structure. See also Figure 1 The axis of symmetry of the first pad 110 (shown by the dashed line) passes through vertex P. Furthermore, the projection of this axis of symmetry onto the sagittal plane also passes through the fifth pad. This significantly reduces the design complexity of the first pad, and the first pad can cover most of the area corresponding to the large motion region.

[0078] Exemplarily, each first pad may further include a fourth edge 114 and a fifth edge 115 sequentially connected to the first edge 111. The fourth edge 114 connects between the first edge 111 and the fifth edge 115. The fourth edge 114 is disposed opposite to the third edge 113. The fourth edge 114 extends from the foremost end of the first pad toward the rear of the subject and obliquely toward the sagittal plane, and the fifth edge 115 continues to extend from the fourth edge 114 toward the rear of the subject. The fifth edge 115 may be located in front of the fifth pad 150, i.e., between the fifth pad 150 and the second pad 120. The fifth edge 115 may be substantially parallel to the sagittal plane of the subject's head. The fifth edges 115 of the two first pads may be disposed side by side and may be spaced apart. Thus, the plurality of probe mounting portions may further include an independent probe mounting portion 262 disposed within a second intersection region 320 between the fifth edges 115 of a pair of first pads 110. The independent probe mounting portion 262 is located on the front side of the fifth pad 150. The distance between the independent probe mounting part 262 and the first pad probe mounting part on the fifth edge 115 meets the preset interval range.

[0079] like Figure 7As shown, the second cross region 320 can be located at the top of the head, adjacent to the first cross region 310. The second cross region 320 is basically close to the highest point of the head, and the curvature from the second cross region to both sides is relatively large. Providing an independent probe mounting part can prevent the padding assembly at the top of the head from bulging. Similar to the independent probe mounting part 261, the independent probe mounting part 262 can also be provided as one or more. Optionally, the distance between the first padding probe mounting parts on the two first pads and one or more of the multiple independent probe mounting parts 262 can meet a preset interval range. In the embodiment shown, since the first pads are symmetrically arranged, the independent probe mounting part 262 is located in the middle position of the two first pads. In an embodiment not shown, the independent probe mounting part 262 may be close to one of the first pads, such that only one first padding probe mounting part and the independent probe mounting part 262 may meet the preset interval range. Exemplarily, there are two independent probe mounting parts 262, arranged along the longitudinal direction. The two independent probe mounting parts correspond to D21 and D22 in the figure, respectively.

[0080] Reference Figure 10 D21 forms detection channels 56 and 6 with the transmitting probes S18 and S2 on the first pad 110 corresponding to the large motion area on the left, and also forms detection channels 88 and 91 with the transmitting probes S28 and S29 on the first pad 110 corresponding to the large motion area on the right. D22 forms detection channel 7 with S2 on the first pad 110 corresponding to the large motion area on the left; forms detection channel 92 with the transmitting probe S29 on the first pad 110 corresponding to the large motion area on the right; and forms detection channels 59 and 101 with the transmitting probes S19 and S32 mounted on the independent probe mounting part 261.

[0081] In some embodiments of this application, see Figure 5A large gap is set between the fifth pad 150 corresponding to the parietal lobe region and the fourth pad 140 corresponding to the occipital lobe region, preventing a direct detection channel from forming between the probes mounted on the fourth pad 140 and the fifth pad 150. The area enclosed by the fifth pad 150, the fourth pad 140, and a pair of first pads 110 is called the third cross region 330. The third cross region 330 is close to the back of the head, and the head shape varies greatly among different subjects in this location. The absence of continuous pads here improves the fit between the headgear and the head, ensuring that the probes in the surrounding area can acquire more accurate fNIRS data. Independent probe mounting parts 263 can be provided within the third cross region 330, thereby increasing the number of detection channels and acquiring more fNIRS data. There can be one or more independent probe mounting parts 263. In the case of multiple independent probe mounting parts 263, they can be arranged along the arc surrounding the fifth pad 150. At least a portion of the independent probe mounting section 263 has a spacing between itself and the probe mounting sections on the adjacent fifth pad 150, fourth pad 140, and a pair of first pads 110 that meets a preset interval range. Thus, at least a portion of the probes mounted on the independent probe mounting section 263 can form more detection channels with the probes mounted on the adjacent pads.

[0082] In the illustrated embodiment, four independent probe mounting portions 263 are provided within the third intersection region 330. The four independent probe mounting portions 263 are distributed along an arc surrounding the fifth pad 150. Thus, each of the four independent probe mounting portions 263 can satisfy a preset interval range in center-to-center distance with the fifth pad probe mounting portion on the fifth pad 150. In this case, at least a portion of the four independent probe mounting portions 263 can satisfy a preset interval range in center-to-center distance with the fourth pad probe mounting portion on the fourth pad 140. Optionally, the four independent probe mounting portions 263 can also be configured such that: each independent probe mounting portion 263 can satisfy a preset interval range in center-to-center distance with the fourth pad probe mounting portion on the fourth pad 140; and a portion of the independent probe mounting portions 263 can satisfy a preset interval range in center-to-center distance with the fifth pad probe mounting portion on the fifth pad 150. The two outermost independent probe mounting portions 263 on the arc are adjacent to a pair of first pads, respectively, so that the center-to-center distance with the adjacent first pad probe mounting portions satisfies a preset interval range.

[0083] like Figure 10As shown, the independent probe mounting section 263 within the third intersection region 330 corresponds to D8, S25, S40, and D28 in the figure. The receiving probes D8 and D28 are located at the two ends of the arc surrounding the fifth pad 150, respectively, so that the receiving probes D8 and D28 can form detection channels 31 and 39 with the transmitting probes S10 and S13 on the two first pads corresponding to the left and right large motion areas, respectively. These probes D8, S25, S40, and D28 form detection channels 130, 78, 128, and 81 with the probes S41, D18, and S26 on the fifth pad 150, respectively. The transmitting probes S25 and S40 also form detection channels 77 and 127 with the receiving probe D17 on the fourth pad 140.

[0084] In summary, referring to Figure 10 With probes arranged in the manner described above, a total of 139 detection channels can be formed by covering all the probe mounting sections in the padding and intersection areas. Of course, depending on the detection needs, probes can also be installed only in some of the probe mounting sections. Alternatively, if all probe mounting sections are covered with probes, other arrangements can be used to form different numbers of detection channels for the target detection area. For example, by using the probe mounting sections of the probe mounting assembly provided in this application, a maximum of more than 130 detection channels can be formed. It is easy to understand that the more detection channels there are, the higher the accuracy of the information obtained on the subdivided brain regions. Therefore, by installing probes in probe mounting sections in different regions, or by changing the type of probe installed in each probe mounting section, accurate detection of almost the entire brain can be achieved.

[0085] Furthermore, by forming at least one of the first cross region 310, the second cross region 320, and the third cross region 330 between adjacent pads, at least one of the independent probe mounting parts 261, 262, and 263 can be provided in the corresponding cross region. This avoids the problem of uneven force distribution caused by connecting the pad assemblies into a large, continuous piece, resulting in bulging, poor fit, and inability to obtain accurate fNIRS data. On the other hand, it allows for the formation of a sufficient number of detection channels to acquire brain activity information more comprehensively and accurately. Moreover, the first cross region 310, the second cross region 320, and the third cross region 330, in conjunction with the first, second, third, fourth, and fifth pads, ensures good correspondence between all probe mounting parts and the human brain structure map, clearly defining the prefrontal, posterior, temporal, gross motor, parietal, and occipital lobes, as well as the subdivided brain regions under these areas. Furthermore, the center distance between the probe mounting parts in each pad, as well as the center distance between the probe mounting part on each pad and the probe mounting part on the adjacent pad and / or the adjacent independent probe mounting part, can meet the predetermined interval range. Therefore, probes can be flexibly arranged on these probe mounting parts, thereby realizing whole brain examination and local detection under limited head size.

[0086] Other probe configuration methods will be provided later, with up to a dozen subset configurations.

[0087] For example, at least a portion of adjacent independent probe mounting portions 261, 262, 263 are connected to each other by connectors 400. Figure 5 As shown, the four independent probe mounting portions 263 can be connected together by the connector 400, thereby limiting the position of these four independent probe mounting portions 263 and ensuring that the spacing between the four independent probe mounting portions 263 does not change excessively. Additionally, the position of the independent probe mounting portion 263 relative to adjacent pads can be limited. This prevents the spacing between the independent probe mounting portion 263 and the probe mounting portions on the adjacent fifth pad 150, fourth pad 140, and a pair of first pads 110 from exceeding a preset interval range. For similar purposes, such as... Figure 7 As shown, the individual probe mounting portions 261 within the first intersection region 310 can also be connected together via connectors 400. The individual probe mounting portions 262 within the second intersection region 320 can also be connected together via connectors 400. In an embodiment not shown, the individual probe mounting portions 261 and 262 can also be connected together via connectors.

[0088] exist Figure 3 and Figure 4In the illustrated embodiment, to improve wearing comfort and / or fit, the second pad 120 may, exemplarily, include a main pad 121 and an auxiliary pad 122. The elastic modulus of the main pad 121 is less than that of the auxiliary pad 122. Therefore, when subjected to the same tensile or compressive force, the main pad 121 is less prone to stretching than the auxiliary pad 122. Optionally, the thickness of the main pad 121 may be greater than the thickness of the auxiliary pad 122. Optionally, the main pad 121 and the auxiliary pad 122 may be made of different materials to achieve different elastic moduli. The main pad 121 is a single piece. The auxiliary pad 122 is independent of each other and independent of the main pad 121. The skull has a significant shape change from the frontal lobe to the parietal lobe. The main pad, being a single piece, does not extend towards the parietal lobe, which improves the fit of the second pad 120 to the forehead area and prevents bulging of the probe after wearing. Furthermore, for areas with significant head shape variations, the auxiliary pad 122, with its high elastic modulus, effectively ensures the spacing between the connected second pad probe mounting portions 220. Exemplarily, the auxiliary pad 122 can be made of the same or similar material as the connector 400. Exemplarily, the auxiliary pad 122 can be secured to the main pad 121 by a snap-fit.

[0089] In the illustrated embodiment, both the main pad 121 and the auxiliary pad 122 are provided with rows of second pad probe mounting portions 220. The main pad 121 has two rows of seven second pad probe mounting portions 220 each. The auxiliary pad 122 can be disposed above and connected to the main pad 121. The auxiliary pad 122 has one row of five second pad probe mounting portions. Optionally, each auxiliary pad 122 can have one second pad probe mounting portion 220. Multiple auxiliary pads 122 can be connected to the main pad 121 respectively.

[0090] For example, the number of second probe mounting portions 220 per row on the main pad 121 is greater than the number of second probe mounting portions 220 per row on the auxiliary pad 122. This allows the first pad corresponding to the large motion area to be avoided. In other embodiments not shown, the number of rows and the number of second probe mounting portions per row on the main pad 121 and the auxiliary pad 122 can be set as needed. The auxiliary pad 122 can be connected to the main pad 121.

[0091] refer to Figure 1 and Figure 10 The second pad probe mounting portions 220 located at the left and right ends of the main pad 121 are closer to the ears in the horizontal direction. At least one of these second pad probe mounting portions 220 can have a center distance that satisfies a preset interval range with the first pad probe mounting portion located above the ears and closest to the forehead (i.e., the first pad probe mounting portion at the third apex 133). Thus, taking the left side as an example again, as Figure 10The transmitting probe S5 on the third pad and the receiving probe D6 on the second pad can form a detection channel 15. Ideally, this detection channel can detect the intersection region of the frontal and temporal lobes. In other embodiments, the detection channel may also be located entirely in the temporal lobe or entirely in the frontal lobe. In other embodiments, the transmitting probe S4 in the present figure may also be configured as a receiving probe, and the center distance between the transmitting probe S5 and the receiving probe meets a preset interval range, thereby forming a detection channel. In yet another embodiment, the transmitting probe S4 in the present figure may also be configured as a receiving probe, and the center distance between it and the transmitting probe S5 in the present figure meets a preset interval range, thereby forming a detection channel. Preferably, the transmitting probe S4 in the present figure may be configured as a receiving probe, and the center distance between it and the transmitting probe S5 in the present figure meets a preset interval range, thereby forming a detection channel. Figure 10 The transmitting probe S5 and the receiving probe D6 form a detection channel 15. The inventors found that this arrangement is more conducive to obtaining fNIRS data of the key brain regions represented by the detection channel 15 (ideally, the detection channel 15 is located at the boundary between the temporal pole and the triangle of the inferior frontal gyrus). Furthermore, when actually worn on the head, the distance between the transmitting probe S5 and the receiving probe D6 allows for the acquisition of better fNIRS data.

[0092] As previously described, the second pad may include a main pad 121 and an auxiliary pad 122. To ensure strength and fit the forehead, the main pad 121 may correspond to a relatively flat area of ​​the forehead and is a single piece extending in the lateral direction. Multiple second pad probe mounting portions 220 are evenly distributed on the single piece, and the center distance between adjacent second pad probe mounting portions 220 meets a preset interval range. The lower part of the main pad 121 may have multiple first cuts 123, such as... Figure 3 and 4 As shown. These first incisions 123 can separate the second padding probe mounting portions 220, at least in the middle of the bottom row, from each other. Thus, when wearing the probe mounting assembly, the opening of the probe mounting assembly is usually opened to cover the forehead protrusion, and in some cases, or due to different head shapes of different subjects, it is necessary to open the opening of the probe mounting assembly even wider. These first incisions 123 allow the opening of the probe mounting assembly to have a certain degree of expansion capability. After the probe mounting assembly is worn on the subject's head, the aforementioned second padding probe mounting portions 220 can maintain a center distance within a preset interval range between each other and between themselves and other adjacent second padding probe mounting portions 220 on the left and right. Thus, under the action of the flexible cover 500, those second padding probe mounting portions 220 that are allowed to move slightly during wearing can return to the desired center distance to smoothly form a detection channel.

[0093] Exemplarily, these auxiliary pads 122 can be arranged in a lateral direction. Exemplarily, each auxiliary pad 122 can be provided with a second pad probe mounting portion 220. The auxiliary pads 122 are located above the main pad 121, and the number of second pad probe mounting portions 220 in each row can be less than the number of second pad probe mounting portions 220 in each row on the main pad 121. This allows for a more comprehensive and complete measurement of the prefrontal cortex, and also avoids the large motor areas and other brain regions of interest that are expected to be measured separately. In addition, one or more openings can be provided on the main pad 121 to improve the fit of the main pad 121.

[0094] For example, in conjunction with reference Figure 5 and Figure 8 The fourth pad and its probe mounting section are arranged similarly to the second pad and its probe mounting section, both using a roughly matrix-like arrangement. The fourth pad can be positioned to correspond to the occipital lobe region and can be joined with the third pad, which can cover the temporal lobe, to form a detection channel. Multiple second incisions 141 can be provided in the lower part of the fourth pad. These second incisions can separate at least a few of the fourth pad probe mounting sections in the bottom row from each other. Thus, when wearing this probe mounting assembly, the opening of the probe mounting assembly is usually opened to cover the most prominent point at the back of the head; in some cases, or due to different wearing habits of different subjects, it may be necessary to open the opening of the probe mounting assembly even wider. These second incisions allow the opening of the probe mounting assembly to have a certain degree of expansion capability. After the probe mounting assembly is worn on the subject's head, it is expected that the center distance between the aforementioned fourth pad probe mounting parts and between them and the other adjacent fourth pad probe mounting parts can maintain a preset interval range. Thus, under the action of the flexible cover 500, those fourth pad probe mounting parts that are allowed to move slightly during wearing can return to the expected center distance to smoothly form a detection channel.

[0095] like Figure 11 As shown, taking the first pad 110 as an example, transmitting probes S3, S4, and S5 are sequentially arranged on the edge of the first pad 110 adjacent to the third pad 130 corresponding to the temporal lobe region. Receiving probes D6, D7, D8, and D9 are sequentially arranged adjacent to the transmitting probes S3, S4, and S5. The transmitting probes S3, S4, and S5, together with the receiving probes D6, D7, D8, and D9, form detection channels. For example, detection channel 30 is formed between the transmitting probe S3 and the receiving probe D6. Detection channels are represented by gray squares in the figure. Other detection channels are similarly formed between adjacent transmitting and receiving probes, and will not be described further here. Figure 11 The probe installation method shown is the same as Figure 10 The difference in the probe installation method shown is that the installation positions of the transmitting probe and the receiving probe are swapped, but the number of detection channels remains unchanged.

[0096] Figure 12 and Figure 13 It shows the relationship with Figure 10 and Figure 11 The illustrations show different probe mounting methods. These methods allow for backward compatibility with fNIRS devices having a relatively small number of probes using the cap of this application, or allow for selective mounting of probes on only some of the probe mounting sections to meet the needs of different target detection areas. That is, only some of the probe mounting sections on the cap are equipped with probes, while the remaining probe mounting sections are left unused. (Reference) Figure 12 The fifth pad probe mounting section, the independent probe mounting section, and the four first pad probe mounting sections of the pair of first pads 110 that are close to each other can be left idle, while the remaining probe mounting sections are used to mount the transmitting probe and the receiving probe. For example, a detection channel can be formed between the transmitting probe S11 and the receiving probes D17 and D21 of the first pad 110. Figure 12 The detection channels are shown as gray lines. In the illustrated probe mounting configuration, in addition to the probe mounting portions of each pad assembly forming detection channels with each other, a detection channel can also be formed between the first pad probe mounting portion 210 and the adjacent third pad probe mounting portion 230. Although the center distance between the third pad probe mounting portion 230 corresponding to S7 and the fourth pad probe mounting portion 240 corresponding to S28 meets the preset interval distance, both are configured as transmitting probes and therefore do not form detection channels. With the illustrated probe mounting configuration, the detection range can cover the forehead area, the greater motor cortex, and the occipital lobe area, and the number of detection channels can reach 76.

[0097] For fNIRS devices with a relatively smaller number of probes, or for subjects whose regions of interest only include the forehead, small motor cortex, and occipital lobe, the number of probes mounted on the cap can be further reduced. For example... Figure 13 As shown, this scheme can form 46 detection channels. The transmitting probe S1 of the third pad mounting part 230 can form a detection channel with the receiving probes D1 and D6 of the first pad mounting part 210. The detection channels are also shown as gray connecting lines.

[0098] It should be noted that, Figure 12 and Figure 13 The diagram only schematically shows the arrangement of the probe mounting parts; the spacing between the probe mounting parts on adjacent pad assemblies does not correspond to the actual probes on the headgear.

[0099] Another aspect of this application provides a headgear for acquiring fNIRS data. This headgear may include the probe mounting assembly mentioned in any of the above embodiments, and probe adapters for mounting to the respective probe mounting portions of the probe mounting assembly. Using the probe mounting assembly of the above embodiments not only facilitates determining the installation position of the probe adapters, but also ensures that the headgear fits snugly against the head without bulging when worn by the subject, and provides sufficient detection channels for accurate detection.

[0100] Another aspect of this application provides a near-infrared brain functional imaging device, which includes an fNIRS data acquisition module, a cable, and a probe, with the cable connecting the fNIRS data acquisition module and the probe. The near-infrared brain functional imaging device may also include a headgear as described in any of the above embodiments, with a probe adapter mounted on the headgear for adapting the probe.

[0101] According to another aspect of this application, a layout of the probe mounting portion and / or the probe on a headgear is provided. This layout is not limited to the headgear provided in the above embodiments, but can be applied to any other suitable type of headgear. In some embodiments, the probe can be directly mounted to the headgear without a probe mounting portion. For example, some probes may have a snap-fit ​​structure, and the headgear has holes for mounting the probe, allowing the probe to be directly snapped onto the headgear via the snap-fit ​​structure. Exemplarily, the headgear may only include any of the flexible coverings 500 described above, using only the flexible covering 500 as a carrier to support these probe mounting portions or probes. Exemplarily, any other suitable carrier can also be used to support these probe mounting portions or probes. This aspect of the application is not intended to limit the structure and shape of the carrier supporting the probe mounting portion or probe.

[0102] In some embodiments, the front of the headgear may include multiple rows of probe mounts arranged laterally, which may at least cover the forehead area of ​​the subject. These probe mounts may also be substantially aligned along the column direction, such that four adjacent probe mounts are generally located at the four vertices of a rectangle or square. For example, the multiple rows of probe mounts described herein may include second pad probe mounts 220 on a second pad 120. When the second pad 120 may include a main pad 121 and a secondary pad 122, the second pad probe mounts 220 on the main pad 121 may be arranged at the four vertices of a rectangle or square, such that the center distance between any two adjacent second pad probe mounts 220 is within a predetermined interval. The second pad probe mounts 220 on the secondary pad 122 may be arranged at the four vertices of a rectangle or square, as well as the second pad probe mounts 220 on the main pad 121, such that the center distance between any two adjacent second pad probe mounts 220 is within a predetermined interval. For example, the number of second pad probe mounting portions 220 per row on the main pad 121 may be greater than the number of second pad probe mounting portions 220 per row on the auxiliary pad 122.

[0103] The aforementioned "multi-row probe mounting section arranged laterally" may also include individual probe mounting sections 261, which are also generally arranged along the row direction. In the illustrated embodiment, the individual probe mounting sections 261 are arranged in only one row. In other embodiments not shown, the individual probe mounting sections 261 may also be arranged in multiple rows. The number of individual probe mounting sections 261 in each row can be set as needed. The individual probe mounting sections 261 may be arranged at the four vertices of the quadrilateral with the second pad probe mounting sections 220 on the auxiliary pad 122, or they may be staggered from the second pad probe mounting sections 220 on the auxiliary pad 122 in the lateral direction. The center distance requirements between the individual probe mounting sections 261 and / or with the center distance requirements with the surrounding probe mounting sections can be referred to the description above. Figure 3 As shown, the two independent probe mounting portions 261 and the adjacent second pad probe mounting portion 220 on the auxiliary pad 122 are arranged to form a roughly quadrilateral.

[0104] In some embodiments, the top of the cap may include a number of probe mounting portions arranged along the line OO where the sagittal plane intersects the surface of the head. For example, one or more probe mounting portions located on the line OO may also be included in front of the parietal lobe region, such as the independent probe mounting portion 262 in the second intersection region 320.

[0105] In some embodiments, the top of the cap may include multiple probe mounting portions capable of covering the top lobe region. These probe mounting portions may be arranged along the vertices of a triangle, see multiple fifth pad probe mounting portions 250 capable of covering the top lobe region. The center distance between each fifth pad probe mounting portion 250 is within a preset interval range. The triangle may be generally an isosceles triangle, an equilateral triangle, or a triangle with roughly different side lengths, such that the center distance between any two adjacent fifth pad probe mounting portions 250 is within the preset interval range.

[0106] In some embodiments, the probe mounting portions on both sides of the headgear can be arranged along the vertices of a triangle. For example, multiple probe mounting portions capable of covering the left and right large motor areas can each be arranged along the vertices of a triangle, see multiple first padding probe mounting portions 210 capable of covering the left and right large motor areas. The center distance between each first padding probe mounting portion 210 is within a preset interval range, and the triangle can be generally isosceles, equilateral, or a triangle with roughly different side lengths, such that the center distance between any two adjacent first padding probe mounting portions 210 is within the preset interval range. For example, multiple probe mounting portions capable of covering the left and right temporal lobe areas can each be arranged along the vertices of a triangle, see multiple third padding probe mounting portions 230 capable of covering the left and right temporal lobe areas. The center distance between each third padding probe mounting portion 230 is within a preset interval range, and the triangle can be generally isosceles, equilateral, or a triangle with roughly different side lengths, such that the center distance between any two third padding probe mounting portions 230 at each vertex of the triangle is within the preset interval range.

[0107] In some embodiments, the rear of the headgear may include multiple rows of probe mounts arranged laterally, which may at least cover the occipital lobe region of the subject. The probe mounts for the occipital lobe region may also be roughly aligned along the column direction, such that four adjacent probe mounts are generally located at the four vertices of a rectangle or square. For example, the multiple rows of probe mounts described herein may include fourth pad probe mounts 240 on the fourth pad 140. These fourth pad probe mounts 240 may be arranged at the four vertices of a rectangle or square, such that the center distance between any two adjacent second pad probe mounts 220 is within a predetermined interval.

[0108] In some embodiments, an intersecting region, such as a third intersecting region 330, may be included between the parietal lobe region, the left and right large motion regions, and the occipital lobe region. A plurality of independent probe mounting portions 263 disposed within the third intersecting region 330 may be arranged along an arc. The requirements for the center-to-center distance between the independent probe mounting portions 263 and / or between them and surrounding probe mounting portions can be referred to the foregoing description.

[0109] The probe is mounted onto some or all of the aforementioned probe mounting parts, allowing for the detection of desired brain regions. The position of the probe mounting parts determines the position of the probe. Given all the aforementioned probe mounting parts, there are many ways to arrange the probes on these mounting parts, as described above. Figure 10-13 The methods described are not exhaustive. Other arrangements are also possible. It should be noted that although the locations where the probe can be installed are described with reference to the probe mounting section, in some embodiments, holes may be provided only on the head cap, and the probe can be directly installed into these holes. Therefore, this document includes embodiments where only holes for probe installation are provided on the head cap, and a probe mounting section is not necessarily required.

[0110] In some embodiments, the first marker hole is formed near FPz. The position of the hole may vary depending on the size of the headgear, the manufacturing process, or the head shape of the subject. Therefore, "near" as used here and below refers to a deviation from the desired position within a preset deviation. Figure 10 As shown, the first landmark aperture near FPz can be included within an aperture that covers the forehead area. (See attached diagram.) Figure 3 and attached Figure 10 This can also be understood as other holes that can cover the forehead area being arranged at preset intervals to both sides of the first landmark hole. For example, roughly in... Figure 10 The location of the transmitting probe S23 shown in the diagram. It should be noted that only [the location shown here] is [of the target location]. Figure 10 The layout is used to describe the location of the first marker aperture near FPz, rather than limiting the aperture near FPz to only being able to mount a transmitting probe. In other embodiments, the aperture may or may not be used to mount a receiving probe.

[0111] In some embodiments, the second marker hole is formed near FZ. For example... Figure 3 and Figure 10 As shown, the second landmark hole near FZ can be included within a hole that covers the forehead area, for example, roughly in... Figure 10 The transmitting probe S22 shown (corresponding to) Figure 3 It is located at the position of the auxiliary pad 122. A receiving probe may or may not be installed here, depending on the need; there is no specific limitation on this.

[0112] In some embodiments, the third marker hole is formed near CZ. The third marker hole near CZ can be located as follows: Figure 7 Within the second intersection region 320 shown, for example, generally in Figure 10The location of the receiving probe D21 is shown in the diagram. Of course, a transmitting probe can also be installed here, or it can be omitted, depending on the needs.

[0113] In some embodiments, the fourth marker pore is formed near Oz. The fourth marker pore near Oz may be included within pores capable of covering the occipital lobe region, for example, generally within... Figure 10 The location of the receiving probe D17 is shown in the diagram. (See attached image.) Figure 5 and attached Figure 10 Alternatively, it can be understood that other apertures covering the occipital lobe region are arranged at preset intervals to both sides of the fourth marker aperture. Of course, a transmitting probe can be installed here as needed, or it can be omitted.

[0114] In some embodiments, the fifth and sixth marker holes are formed near C3 and C4, respectively. The fifth and sixth marker holes may be contained within holes capable of covering the large left and right motion areas, for example, generally within... Figure 10 The locations of transmitting probes S8 and S33 are shown in the diagram. Of course, receiving probes can also be installed at these locations as needed, or they can be omitted; this application does not specifically limit this. The fifth and sixth marker holes near C3 and C4 can be generally located at the center of all holes capable of covering the large left and right movement areas. For example, combined with... Figure 2 and Figure 10 The holes near C3 and C4 can be located approximately at the center of a pair of first gaskets 110, and the axis of symmetry PP of the pair of first gaskets 110 can pass through the fifth and sixth mark holes near C3 and C4, respectively.

[0115] In some embodiments, the locations of the various marker holes can be marked on the outer surface of the cap. For example, labels can be placed on the probe mounting parts of the marker holes, or markings can be printed on the cap, to facilitate operators in identifying the wearing position of the cap and installing the probe in the corresponding position when performing fNIRS data acquisition. In some other embodiments, only a portion of the marker holes may be marked on the outer surface of the cap, or more marker holes may be marked, as long as it facilitates fNIRS data acquisition by the operator. This application does not impose specific limitations on this.

[0116] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "rear", "up", "down", "left", "right", "lateral", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0117] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0118] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0119] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar subjects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0120] This application has been described through the above embodiments.
