Description

Technical Field

[0001] The utility model belongs to the technical field of near-infrared brain imaging equipment, in particular to a combined near-infrared brain function imaging helmet. Background Art

[0002] Functional near-infrared spectroscopy (fNIRS) is a spectral analysis technology that calculates the concentration and changes of oxygenated hemoglobin and deoxygenated hemoglobin in blood vessels through changes in optical density to monitor the brain's neural activity. Near-infrared brain function detection equipment is a brain function detection equipment based on optical principles. This technology uses a specific light source to illuminate the head of the person being tested through a transmitting optical fiber, and then uses a receiving optical fiber to approach the person's scalp at a specific distance from the irradiation point to receive the reflected light signal. Each light source irradiation point and detection point form a detection channel.

[0003] When using near-infrared spectroscopy brain function imaging equipment, multiple laser probes need to be fixed to the skin surface of the user's brain to achieve the arrangement of multiple detection channels on the user's head. Generally speaking, doctors will use the acquisition bracket directly connected to multiple laser probes on the equipment to directly cover the user's brain, and tighten the straps on the acquisition bracket to fix the acquisition bracket to the user's brain. However, since the acquisition bracket connected to multiple laser probes is heavy and the fixing ability of the straps is weak, the acquisition bracket is prone to shifting during the test, interfering with the fit between the user's brain skin and the probe, and ultimately affecting the accuracy of the test results.

[0004] The utility model patent with application number 202220658794.0 discloses a near-infrared brain imaging head cap that is resistant to motion interference. By setting a head cap with an elastic black cloth cover and connecting a strip of cloth chin support to the lower end of the head cap body, the fixation between the head cap and the user is strengthened to ensure the fit between the user's brain and the acquisition device. However, although the chin rest of the patent is elastic, it cannot adjust the elasticity according to the brain size of different users to adjust the tightness of the head cap. For some users with larger head circumferences, it will be too tight, affecting the wearing comfort; while users with smaller head circumferences will feel too loose, affecting the fitting effect of the probe, and cannot fully adapt to users with different head circumferences. In addition, since the tightness of the head cap cannot be actively adjusted, the wearing conditions of different users are different, which in turn leads to differences in the installation position of the probe, ultimately affecting the brain function imaging results; the head cap of the patent needs to cut off the nylon injection hook block before use, the use process is cumbersome and the service life of the head cap is short; in addition, the probe of the patent is located at the back of the head cap, and it is impossible to detect other parts of the user, such as the forehead, and cannot meet the application requirements of forehead detection of the user. Therefore, it is urgent to provide a helmet that can solve the above problems. Utility Model Content
