Problems solved by technology

[0006] Aiming at the problem that when wearing a headgear for near-infrared spectrum brain imaging detection, the detection probe is often unable to directly contact the scalp due to hair cover, which affects the detection sensitivity and data collection. This patent designs a new type with high sensitivity. A near-infrared spectrum brain imaging detection device for data collection. The detection device contains two layers of parts that separate the hair, which can completely avoid the interference of human hair during use, significantly improve the detection sensitivity and data collection rate, and has a good application prospect.

Embodiment 1

[0045] Such as Figure 1~3 As shown, this embodiment provides a near-infrared spectrum brain imaging detection device with high-sensitivity data acquisition, including a headgear 1 , a probe 2 , a rotating part 3 , a sleeve 4 and a connecting piece 5 . The headgear 1 is provided with a plurality of detection interfaces 101 , and the detection interfaces 101 are arranged in an array in the entire area of ​​the headgear 1 , and the probe 2 is connected to the detection interfaces 101 through the connecting piece 5 . The sleeve 4 is sheathed on the outer periphery of the detection end 201 of the probe 2, and the head of the sleeve 4 includes two openable and closable opening parts 401, and the two opening parts 401 form a thick mushroom head when closed shape; on the one hand, the shape of the head of the sleeve 4 can contact the hair in an arc shape, which avoids the scratch or puncture of the sleeve 4 on the human head, and has a buffering and protective effect; on the other ha...

Embodiment 2

[0051] Such as Figure 4~5 As shown, the difference between this embodiment and Embodiment 1 is that the rotating part 3 uses an automated mechanical rotating part 302 instead of a manual rotating part 301 .

[0052] The mechanical rotating part 302 is arranged on the outer side of the movable connecting part 502 away from the head of the human body, on the upper end surface of the movable connecting part 502, and the mechanical rotating part 302 is fixedly connected with the movable connecting part 502; The mechanical rotating part 302 is a shaft, and the mechanical rotating part 302 is connected with the servo motor 303. The servo motor 303 is a miniature servo motor. By setting the step angle of the servo motor 303, the rotation direction and angle of the probe 2 can be realized. .

[0053] Specifically, a shaft coupling 304 is provided between the mechanical rotating member 302 and the servo motor 303 , and the coupling 304 includes an elastic piece to protect the probe 2...

Embodiment 3

[0056] Such as Figure 6As shown, in this embodiment, the rotating parts of the actuators of the two rotating actions in Embodiments 1 and 2 are combined and arranged on the movable connecting member 502, and one of them can be selected to be used or both can be used at the same time according to the specific situation. One, the manual rotating part 301 can handle some special situations such as hair entanglement by manual control, and the mechanical rotating part 302 can handle the situation of general hair covering, and it has the advantages of fast, labor-saving, and human body feeling comfortable.

[0057] As a further supplement to this embodiment, the mechanical rotating part 302 is arranged on the outer side of the movable connecting part 502 away from the head of the human body, and is located at the center of the upper end surface of the movable connecting part 502. The mechanical rotating part 302 is connected to The connecting part 502 is fixedly connected. Since th...

Abstract

The invention discloses a highly sensitive NIR (Near Infrared Spectrum) brain imaging detector for data collection, comprisingcaps, probes, rotational parts and sleeves; thecaps are provided with multiple detection interfaces, the probes are connected with the detecting interfaces through connecting pieces; the rotational parts are connected with the probes throughconnecting pieces, and control the rotation of the probes; the sleeves sleeve the periphery ofdetecting ends of the probes, and heads of the sleeves contain multiple poking pieces capable of being opened and closed. The NIR brain imaging detector further comprises an opening and closing control device that controls the poking pieces. The detector disclosed by the invention is provided with two layers of components for poking hair in design, can avoid the interference of human hair completely, improves the sensitivity and data collection rate of detection obviously, is comfortable for human body in use, and has excellent application prospects.

Description

technical field [0001] The present invention relates to the technical field of near-infrared spectrum brain imaging, and more specifically, to a near-infrared spectrum brain imaging detection device with high-sensitivity data acquisition. Background technique [0002] In recent years, the development of optical imaging technology has provided a new and important research method for detecting cognitive activity process and neural mechanism. The basis of optical imaging is that the activity of neurons will cause changes in some related substances (such as water and ions), resulting in changes in their optical properties, and corresponding optical signals will be obtained after interacting with externally applied light quanta of specific wavelengths. . The spatial distribution of the optical signal within a certain time interval is detected by the imaging instrument system to form an image. [0003] There are many kinds of optical imaging, among which near-infrared spectrosco...
