Referring to fig. 1 to fig. 3, the brain imaging detecting apparatus 100 according to the present invention is used for collecting signals in the brain of a human head, and medical staff performs pathological analysis according to the signals, so as to diagnose diseases.
Specifically, the brain imaging detection device 100 includes a plurality of detectors 20, a plurality of near-infrared light sources 30, and a head cover 10 with an opening at one end, the head cover 10 can be sleeved on the head of the human body and contacts with the hair, the detectors 20 and the near-infrared light sources 30 are disposed on the inner side of the head cover 10 facing the head of the human body, the detectors 20 are used for detecting information in the brain of the head of the human body, and the near-infrared light sources 30 are used for providing light sources for the detectors 20.
Further, the headgear 10 is a flexible headgear. It can be understood that the inner side of the head cover 10 contacts the scalp, and the use of the flexible head cover can prevent the scalp from being scratched, thereby preventing the user from feeling uncomfortable.
In this embodiment, the flexible headgear is made by mixing one or more materials selected from Polydimethylsiloxane (PDMS), Polydopamine (PDA), rubber, and hydrogel. Of course, in other embodiments, the flexible headgear may also be made of one or more flexible materials selected from Shape Memory Polymer (SMP), Polyurethane (PU), and dielectric elastomer, or one or more blends of other materials.
Along the thickness direction of the head cover 10, that is, towards the head of the human body, a plurality of through holes 11 are formed in the head cover 10, the plurality of through holes 11 enable the head cover 10 to form a net-shaped structure, the detector 20 and the near-infrared light source 30 are arranged adjacent to the through holes 11, when the head cover 10 is sleeved on the head of the human body, the hair of the head of the human body can penetrate out of the through holes 11, and therefore the surface of the inner side of the head cover 10 and the detector 20 and the near-infrared light source 30 located around the through holes 11 can be attached to the scalp.
Preferably, the plurality of through holes 11 are distributed in an array, the inner side of the head cover 10 is arc-shaped, and the plurality of through holes 11 are distributed in an approximately rectangular array, so that the plurality of through holes 11 can be distributed in the head cover 10 at intervals and uniformly, thereby facilitating the omni-directional arrangement of the devices, such as the detector 20 and the near-infrared light source 30 mentioned above.
It is known that a cylindrical hole penetrating along the thickness direction of the headgear 10, that is, a cross section of the through hole 10 perpendicular to the thickness direction of the headgear 10 is circular, and the circular shape has the largest area compared to the square shape or the triangular shape at the same circumference length, so that more hairlines can be inserted therein.
Further, the diameter of the through hole 11 ranges from 5mm to 15 mm. It should be explained that the diameter of the through hole 11 is set too small, which is not beneficial to the distribution of human hair, and the through hole 11 is set too large, which can narrow the arrangement space and range of the device, and can not collect signals in the brain in some areas; and in this application, be 5mm ~ 15mm with 11 diameter scope of through-hole, not only be favorable to the allotment of human hair, can also leave sufficient space device of arranging simultaneously to gather brain internal signal all-roundly.

It should be noted that the alternate arrangement means that one infrared light source 30 and one detector 20 are spaced and staggered along the longitude direction inside the head cover 10, and similarly, one near infrared light source 30 and one detector 20 are spaced and staggered along the latitude direction inside the head cover 10, so that each near infrared light source 30 is adjacent to a detector 20, and thus the near infrared light sources 30 can provide light sources for a plurality of adjacent detectors 20 at the same time. The node area of the mesh structure means that a plurality of through holes 11 are arranged in multiple rows and multiple columns, the through holes 11 in each row are arranged at intervals, and along the gap connecting line between each row of through holes 11 and the adjacent through holes 11, and the through holes 11 in each column are arranged at intervals, along the gap connecting line between each column of through holes 11 and the adjacent through holes 11, the intersection points of the multiple rows of connecting lines and the multiple columns of connecting lines form nodes, the node area is formed between each node, and the through holes 11 are located in a grid formed by the node area.
