TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field especially, relate to a kind of brain function imaging integrated short channel function double-port probe and equipment. BACKGROUND
[0002] Functional Near-Infrared Spectroscopy (fNIRS) uses the absorption and scattering relationship between multiple wavelengths of near-infrared light and chromophore substances in the brain tissue (such as oxyhemoglobin, deoxyhemoglobin, etc.) to investigate the concentration changes of these substances in the brain tissue under certain conditions. These concentration changes can indirectly reflect the activities of neurons, cellular energy metabolism, and blood dynamics-related functions, thereby revealing the state and processing of the brain. Specifically, when the brain is active, the cerebral oxygenation in the active area increases, leading to an increase in the concentration of oxygenated hemoglobin and a decrease in the concentration of deoxyhemoglobin in the cortical tissue of that area. These changes affect the propagation of light in the brain tissue, which is captured by the near-infrared brain function imaging device. By analyzing these changes in light, the activity of the brain can be inferred.
[0003] When collecting cerebral oxygen, the path of near-infrared light transmission is scalp-skull-cerebrospinal fluid-brain parenchyma. Since there is blood flow in the scalp, it is inevitable to collect the scalp oxygen changes during the collection of cerebral oxygen. Therefore, the collection of cerebral oxygen is disturbed by the changes in scalp oxygen.
[0004] The common method to remove the interference of scalp oxygen changes is to additionally increase a collection channel close to the light source to collect the changes in scalp oxygen, and finally remove the changes in scalp oxygen from the total collected cerebral oxygen change curve to eliminate the interference. This method of collecting scalp oxygen requires an additional collection port, increasing the complexity of the device and making it more cumbersome to use. Moreover, the distance between the light source end and the scalp cannot be very close, which may also collect cerebral oxygen, and cannot collect pure scalp oxygen. SUMMARY

[0026] In the first embodiment, the first probe 101 and the second probe 102 are in an elongated structure, and the end thereof can conveniently pass through the hair to contact the scalp. Since the structure of the first probe 101 and the second probe 102 arranged on the shell 100 is fixed, the light source emitting-receiving path between the first probe 101 and the second probe 102 is fixed, thereby ensuring that the light source emitted by the emitting unit 201 is received by the receiving unit 202, and the light source emitting-receiving path is exactly capable of collecting the scalp blood oxygen information data, avoiding human operation, so that the light source emitting-receiving path falls on the scalp and the next layer, thereby collecting the brain marrow or other brain blood oxygen, and affecting the purity of the collected scalp blood oxygen information data.
[0027] In the second embodiment, the structure of the first probe 101 and the second probe 102 on the shell 100 is not fixed, or only one of the first probe 101 and the second probe 102 is fixed on the shell 100.
