Fig. 1 illustrates an external structural schematic view of a headgear of a near infrared brain function imaging device according to an embodiment of the present application.

The application provides a headgear of near infrared brain function imaging device, the headgear includes cover 1, mounting 3 and probe coupling mechanism. The cover 1 is used for covering the head of a subject, and the plurality of first probe adapters 2 are arranged on the cover 1 and penetrate through the cover 1 for installing probes. Specifically, the cover 1 can be worn on the head of the subject and attached to the head of the subject. Wherein, the cover body 1 can be made based on elastic cloth to realize better cladding effect to the head of the testee through the elastic cloth. Wherein the fixture 3 is fixed to the housing 1, the fixture 3 may be arranged close to the first probe adapter 2. In some embodiments, the fixing member 3 may be formed of a screw penetrating through a mounting hole in the cover 1 and a nut for fixing the fixing member 3 to the cover 1 by cooperating with the screw. In other embodiments, the fixing member 3 may be composed of a first fastening member and a second fastening member, where the first fastening member penetrates through a mounting hole on the cover 1 and is fastened with the second fastening member on the other side of the cover 1. By way of example only, the structure of the mount 3 is not particularly limited.

The helmet further comprises a probe connecting mechanism, wherein the probe connecting mechanism is used for adjusting the distance between the first probe adapter 2 and the fixing piece 3, so that probes arranged on the probe adapters can be tightly attached to the head of a testee, the probe connecting mechanism is arranged on the outer side of the cover body 1, and the outer side of the cover body 1 refers to the side facing away from the head of the testee. The specific position of the probe connecting mechanism arranged outside the cover body 1 is not limited, and can be determined based on the actual manufacturing condition of the headgear. The probe connection mechanism includes a first connection member 4, a second connection member 5 and a locking member 6, as shown in fig. 1, the first connection member 4 is rotatably connected to at least one of the first probe adapter 2 and the locking member 6, the second connection member 5 is rotatably connected to the fixing member 3 and the locking member 6, and the first connection member 4 and the second connection member 5 are rotated to a predetermined position to enable the probe to be abutted against the head of the subject. The preset position is not specifically limited, and the preset position may be set manually based on actual conditions, so that the probe can be closely attached to the scalp after the first connecting piece 4 and the second connecting piece 5 rotate to the preset position.

Further, the locking member 6 is used to lock the first connector 4 and the second connector 5 to the housing 1 after the first connector 4 and the second connector 5 are rotated to the predetermined positions, so that the probe mounted on the probe adapter can be held in a state of being closely attached to the head of the subject. Through the cooperation of first connecting piece 4, second connecting piece 5, mounting 3 and locking piece 6, can adjust the interval of first probe adapter 2 and mounting 3, the cover body 1 of head cap is contracted to make each probe that installs on the head cap can hug closely the head of testee. The first connecting piece 4 and the second connecting piece 5 are rotated, so that the first connecting piece 4 and the second connecting piece 5 reach preset positions, probes on each probe adapter can be attached to the head of a testee, the locking piece 6 further presses the first probe adapter 2 in the process of locking the first connecting piece 4 and the second connecting piece 5, the attaching degree of the probes on each probe adapter to the scalp is further increased, and even if the head shape and the head circumference of the testee differ from the head cap in size too much, each probe can attach to the scalp of the testee, so that the brain function imaging equipment connected with the head cap can obtain better measuring results.

In particular, the fastening element 3 may be provided separately on the housing 1 or may be configured as a probe adapter, for example of another brain region (see fig. 1). For example, the pillow leaf is provided with probe adapters correspondingly, and one of the probe adapters can be selected as the fixing member 3 (see fig. 1). Alternatively, the occipital lobe is provided with a part of the first probe adapter 2 and a part of the fixture 3, and the fixture 3 may be other devices having a fixing function instead of the probe adapter.

The first connecting piece 4 and the second connecting piece 5 may be movable connecting pieces, and holes are formed at two ends of each connecting piece, so that the first probe adapter 2 is combined with one end of the first connecting piece 4, which is a connecting piece, the locking piece 6 is combined with the other end of the first connecting piece 4, which is a connecting piece, and the fixing piece 3 is combined with one end of the second connecting piece 5, which is a connecting piece, the locking piece 6 is combined with the other end of the second connecting piece 5, which is a connecting piece, and the specific structure is not limited, so long as the first probe adapter 2 and the locking piece 6 can be connected, and the fixing piece 3 and the locking piece 6 can be connected. The locking element 6 is understood to be a structural element which can be fastened to the housing 1 together with the first connecting element 4 and the second connecting element 5. The position of the locking piece 6 on the cover body 1 is adjusted, and the first connecting piece 4 and the second connecting piece 5 can be driven to rotate around the first probe adapter 2 and the fixing piece 3 respectively, so that the cover body 1 is contracted or expanded, and the fitting degree of the probe arranged on the head cap and the head is changed. The mounting positions of the first probe adapter 2 and the fixture 3 connected to the probe connection mechanism are not fixed, and the user may adjust the probe adapter according to the head shape and head circumference of the subject, and preferably the first probe adapter 2 to be connected to the probe connection mechanism may be the first probe adapter 2 at the outer edge position among the plurality of first probe adapters 2 corresponding to the brain region.

It will be appreciated that the number of locking members 6, as well as the number of other connectors used to connect different locking members 6, may be determined based on the distance between the first probe adapter 2 and the fixture 3 to be compacted or the degree of fit of the probe to the scalp. For example, when the distance between the first probe adapter 2 and the fixing member 3 is relatively short, a locking member 6 may be provided between the first probe adapter 2 and the fixing member 3, so that the probes mounted on the respective first probe adapters 2 can be brought into close contact with the head by rotating the first connecting member 4 and the second connecting member 5. When the distance between the first probe adapter 2 and the fixing piece 3 is far, a plurality of locking pieces 6 can be arranged between the first probe adapter 2 and the fixing piece 3, and connecting pieces for connecting different locking pieces 6 are arranged, so that the degree of freedom of the probe during adjustment is improved, and probes arranged on the first probe adapters 2 are tightly attached to the head by rotating the connecting pieces 5. The locking element 6 may be a combination of a threaded rod and a locking nut, wherein the threaded rod is provided with an external thread. One end of the first connecting piece 4 is sleeved on the first probe adapter 2, one end of the second connecting piece 5 is sleeved on the fixing piece 3, the other ends of the first connecting piece 4 and the second connecting piece 5 can be overlapped and sleeved on the screw rod, an operator can enable the probe to be attached to the head of a tested person by rotating the first connecting piece 4 and the second connecting piece 5, at the moment, the first connecting piece 4 and the second connecting piece 5 reach a preset position, and the rotation locking is carried out through the threaded fit between the locking nut and the screw rod. According to the conductivity of the force, when the locking piece 6 is used for locking the first connecting piece 4 and the second connecting piece 5, the first probe adapter 2 and the fixing piece 3 are pressed on the cover body 1, so that the fitting degree of the probes on the probe adapters on the head caps and the scalp can be adjusted through the fixing effect of different probe connecting mechanisms, and therefore, when the head caps are used by testees with different head types and head circumferences, the probes arranged on the first probe adapter 2 can be well fitted on the head, and more accurate near infrared data can be acquired.

In some embodiments of the present application, the headgear further comprises a carrying portion disposed inside the cover 1, and the inside of the cover 1 is a side facing the head. As indicated by the dotted line in fig. 1, the area indicated by the dotted line corresponds to the bearing portion area provided inside the cover 1. Fig. 1 shows a schematic view of the outer structure of the head cap, and therefore, the region shown by the broken line shows the position of the inner bearing portion of the head cap, which is merely an example. Further, the plurality of first probe adapters 2 are further configured to sequentially penetrate the cover 1 and the carrier portion to enable the probe to contact the head of the subject. In particular, the carrier part may be an entire sheet-like body, for example, on which a plurality of first probe adapters 2 and/or holders 3 are arranged. Alternatively, the carrier may be small pieces, each of which may be provided with a first probe adapter 2 or a holder 3. Wherein, a slice carrying part and a brain area are correspondingly arranged, or a carrying part slice area formed by the carrying parts of a plurality of small slice bodies is correspondingly arranged.

Further, for example, a plurality of first mounting holes are formed in the cover body 1, a plurality of second mounting holes are formed in the bearing portion, the first mounting holes and the second mounting holes are arranged in one-to-one correspondence, and the first probe adapter 2 is connected to the headgear through the first mounting holes and the second mounting holes. Assuming that the first probe adapter 2 includes a first fastening member and a second fastening member, the first fastening member penetrates through the first mounting hole and the second mounting hole from the outer side of the housing 1, and is fastened with the second fastening member on the inner side of the bearing portion, so that the first probe adapter 2 can be fixed. This is merely an example and does not constitute a specific limitation on the scope of protection of the claims.

Specifically, the hardness of the bearing part is greater than that of the cover body 1, and the bearing part can be made of a material with hardness not exceeding a first threshold value, and the first threshold value can be set manually. For example, each bearing part is made of silica gel, each silica gel sheet corresponds to different brain regions, and as the silica gel sheets have certain hardness, the head caps can be kept from being pulled violently when facing different head shapes or head circumferences, so that the distance between the transmitting probe and the receiving probe is kept within a certain range (for example, the fixed distance between the transmitting probe and the receiving probe is about 3 cm), and the near infrared brain function imaging device is facilitated to obtain better near infrared data. It can be understood that when the near infrared light emitted by the emission probe vertically enters the head, the acquired near infrared data has high accuracy, and because the hardness of the silica gel sheet can reduce the retractility of the head cap, the angle can be kept, so that a user can acquire more accurate near infrared data by using the head cap of the near infrared brain function imaging device.

It will be appreciated that the carrier may be provided separately for different regions of the subject's brain, e.g. the carrier may correspond to a region of motion, temporal lobe, occipital lobe, etc. to accurately assess brain function. And, the cover body 1 can adopt the material that can laminate human scalp, and biocompatibility is good, can not arouse human allergy to increase the comfort level of headgear, improve the user experience of testee. The distance between the probe adapters distributed on the bearing part is set in a certain range, so that the near infrared brain function imaging equipment can obtain a better measurement result.

In some embodiments, the carrier comprises a first carrier 7 and a second carrier 8. As shown in fig. 1, the first carrying portion 7 is disposed corresponding to the first brain region, and the first carrying portion 7 includes a plurality of first probe adapters 2. The second bearing part 8 is arranged corresponding to the second brain region, and a plurality of second probe adapters are arranged on the second bearing part 8. The first brain region and the second brain region can be replaced by any one of brain regions such as occipital lobe, temporal lobe and movement region. In fig. 1, the first bearing part 7 corresponds to a movement area, and may be disposed in other positions such as occipital lobe, temporal lobe, forehead lobe, etc. in practice, and the second bearing part 8 may be disposed in other brain areas adjacent to the first bearing part 7, which is merely an exemplary illustration.

In some embodiments, at least one of the second probe adapters is configured as the fixing element 3, that is, some fixing elements 3 may be second probe adapters disposed on the cover 1, the second probe adapters may have the same structure as the first probe adapters 2, the second probe adapters are disposed on the cover 1 and penetrate the cover 1 for mounting probes, and the first connecting element 4 and the second connecting element 5 are rotated to a preset position so that the probes mounted on the first probe adapters 2 and the second probe adapters can be abutted against the head of the subject.

In some embodiments, the first brain region and the second brain region are adjacent brain regions, wherein the first connector 4 is rotatably connected to the first probe adapter 2 and the locking member 6 disposed at an edge position of the first carrier part 7, and the second connector 5 is rotatably connected to the fixing member 3 and the locking member 6 disposed at an edge position of the second carrier part 8 close to the first carrier part 7. Because the first bearing part 7 and the second bearing part 8 which are arranged on the inner layer of the head cap have certain hardness and thickness, and the head of the detected person has certain radian, the probe adapter which is arranged at the edge positions of the first bearing part 7 and the second bearing part 8 is easy to tilt, and the assembled probe cannot be well attached to the scalp. By arranging the probe connecting mechanism between different bearing parts and rotating each connecting piece in the probe connecting mechanism, the situation that the edge of each bearing part is tilted in the compaction process is avoided, and the sticking effect of the probe on the scalp is realized.

At least one of said locking elements 6 is arranged between adjacent carriers for connecting probe adapters located on different carriers, respectively. The carrier portion is sized to cover at least the corresponding brain area, e.g. the second carrier portion 8 at the occipital lobe is sized to cover at least the occipital lobe. The movement zone may include a portion of the frontal lobe and a portion of the parietal lobe. In general, as shown in fig. 1, a plurality of first probe adapters 2 are disposed on the first carrying portion 7, a plurality of second probe adapters are disposed on the second carrying portion 8, and the first carrying portion 7 and the second carrying portion 8 are adjacent to each other. The locking piece 6 is arranged between the adjacent first bearing part 7 and second bearing part 8, and the probe adapter on the adjacent first bearing part 7 and second bearing part 8 is pressed by the first connecting piece 4, the second connecting piece 5 and the locking piece 6, so that the fitting degree of the head cap and the scalp can be further improved. The number of locking elements 6 can be selected according to the distance between the two probe adapters to be connected and the degree of freedom required for the adjustment of the probe, so that the locking elements are suitable for heads with different head shapes and head circumferences. Wherein the probe adapter connected by means of the locking element 6 may be one or two. Furthermore, the first probe adapter 2 and the second probe adapter, which are connected by the probe connection mechanism, are located at the edge position of the first carrier part 7 and the edge position of the second carrier part 8, which is close to the first carrier part, respectively.

In some embodiments, the adjacent brain regions comprise at least one pair of occipital-temporal, occipital-motor, temporal-frontal, wherein the motor comprises a portion of the frontal lobe and a portion of the parietal lobe. In general, the head shape of the subject is affected, and the fitting degree between the probe and the scalp, which are disposed at the positions close to the occipital lobe, the movement region and the temporal lobe and at the positions close to the occipital lobe and the movement region, is poor, so that it is difficult to acquire accurate near infrared data. This embodiment provides for the occipital, movement zone and temporal lobes to be correspondingly provided with bearings, and a first probe adapter 2 and/or a fixture 3 on each bearing. The first probe adapter 2 positioned at the edge position of the first bearing part 7 of the movement area and the fixing piece 3 positioned at the edge position of the second bearing part 8 of the pillow leaf and close to the first bearing part 7 are respectively connected by the first connecting piece 4 and the second connecting piece 5, the first connecting piece 4 and the second connecting piece 5 are fixed by the locking piece 6 by rotating the first connecting piece 4 and the second connecting piece 5 to the preset position, and the cover body 1 is contracted by the conduction of force, so that probes on each probe adapter on the cover body 1 can be tightly attached to the head of a person to be examined. The examples are illustrative only and are not intended to limit the scope of the specific protection.

In some embodiments, the locking member 6 is a plurality, and the probe connection mechanism further includes a third connection member 9, where the third connection member 9 rotatably connects each of the locking members 6. As shown in fig. 1, the distance between two probe adapters located on the bearing part corresponding to the temporal lobe and the second bearing part 8 corresponding to the occipital lobe adjacent to the temporal lobe is relatively far, and in order to make the probes on each probe adapter on the cover body 1 cling to the head, two locking pieces 6 can be arranged between the two probe adapters for connection, so as to improve the degree of freedom when the probes are adjusted, the two locking pieces 6 are respectively connected with the two probe adapters on the adjacent brain regions through connecting pieces, and the two locking pieces 6 are rotatably connected through the third connecting piece 9. If the number of locking pieces 6 arranged between two probe adapters is greater than two, the two locking pieces 6 at the two ends are respectively connected with the probe adapters on the adjacent brain areas through the first connecting piece 4 or the second connecting piece 5, and the locking pieces 6 are sequentially connected in a rotatable mode through the third connecting piece 9.

Specifically, for example, when the distance between the first probe adapter 2 and the fixing member 3 at the edge positions of the first bearing part 7 and the second bearing part 8 is relatively close, a locking member 6 may be used to combine with the first connecting member 4 and the second connecting member 5 to form a probe connecting mechanism, where the first connecting member 4 and the second connecting member 5 are fixedly connected with the first probe adapter 2 and the fixing member 3 at the edge positions of the first bearing part 7 and the second bearing part 8, respectively. When the distance between the two probe adapters is relatively long, at least two locking members 6 may be used in combination with the first connector 4, the second connector 5, and the plurality of third connectors 9. The various components of the probe attachment mechanism are removable. Specifically, the fitting degree of the single probe adapter or the plurality of probe adapters to the scalp can be adjusted by adjusting the number of the locking pieces 6 and the respective connecting pieces, the mounting positions and other relevant parameters. In the process of adjusting the fitting degree of the probe adapter and the scalp, a user can also adjust the fitting degree of the whole head cap to a certain degree according to the conductivity of force.

In some embodiments, as shown in fig. 2, the bearing portion is disposed corresponding to the movement area, and the outer edge portion of the bearing portion includes a plurality of first through holes 10, and the interior of the bearing portion includes a plurality of second through holes 11 (i.e., the second through holes 11 are closer to the central position of the bearing portion than the first through holes 10), and the area of the second through holes 11 is larger than that of the first through holes 10. The motion district corresponds bear portion and is compressing tightly the in-process, the perk scheduling problem appears easily, through set up first through-hole 10 and second through-hole 11 on bearing portion to make the area of second through-hole 11 be greater than the area of first through-hole 10, make the motion district correspond bear portion and can follow the head form better when compressing tightly, prevent perk scheduling problem, make it laminate the head more easily, and the setting of first through-hole 10 and second through-hole 11 can also increase the gas permeability of headgear. Wherein, in other embodiments, the second through hole 11 is at least one of triangle, quadrangle, and circle. In addition, the occipital lobe, the forehead lobe and the temporal lobe can be provided with through holes for increasing air permeability, comfort and freedom degree. The number, area, etc. of the first through holes 10, the second through holes 11, and other respective through holes may be adjusted based on the size of the headgear.

In some embodiments, the edge of the first carrier 7 corresponding to the movement region may include a protrusion corresponding to the outer edge of the first probe adapter 2, and the protrusion has a curvature bent toward the scalp side, so that the edge of the first carrier 7 is prevented from tilting when the first probe adapter 2 corresponding to the movement region is pressed.

In some embodiments, as shown in fig. 3, the bearing portion is disposed with the pillow She Duiying, the bearing portion corresponding to the pillow leaf includes a body 12, a plurality of end portions 13 and a plurality of connection portions 14, the plurality of end portions 13 are disposed below the body 12, each end portion 13 is disposed in one-to-one correspondence with each connection portion 14, each end portion 13 is connected to the body 12 via the corresponding connection portion 14, and the body 12 and the plurality of end portions 13 may be provided with the first probe adapter 2. The bearing portion provided corresponding to the pillow leaf may be the second bearing portion 8 shown in fig. 1. Further, the width of the connecting portion 14 is smaller than the width of each of the end portions 13.
