Description
Technical Field
The invention relates to the field of medical treatment, in particular to a light source emission detection probe with an integrated structure.
Background
The living cells or tissues of the human body, whether in a static state or an active state, generate a regular electrical phenomenon closely related to the life state, which is called bioelectricity. By adopting a high-precision weak bioelectricity signal acquisition technology, various electrophysiological signals of a human body including electroencephalogram, myoelectricity, electrocardio and the like can be acquired, and the acquired data are analyzed and stored. The electroencephalogram is the weakest signal in all biological electric signals, the signal with the highest collection difficulty contains electrophysiological activity information of a large number of brain nerve cells, the information such as thinking activity and limb actions of a human can be reflected, and electroencephalogram (EEG) is used as a mature brain function detection technology, has higher time resolution and has the defect of poorer spatial resolution. The near-infrared brain function imaging (fNIRS) technology is based on the optical characteristics of biological tissues, combines the propagation rule of light in the tissues, utilizes the good penetrating power of near-infrared light on the tissues, and researches biochemical information carried by emergent light after a series of absorption and scattering in the tissues and related to the optical characteristics of the tissues, and mainly aims to research the quantitative measurement of the concentration of absorption chromogens (such as oxyhemoglobin, deoxyhemoglobin and the like) in the tissues and provide convenient and reliable monitoring indexes for clinic and research by obtaining useful information related to the tissue structure and physiological functions. Researchers can adopt the fNIRS to obtain the change of the blood oxygen level during brain activity, and then study nerve activity, and since the fNIRS has the advantages of small volume, light weight, high spatial resolution, wide range of testees and the like, the fNIRS is gradually used for brain study in the fields of cognitive nerves and the like. The advantages of both spatial and temporal resolution can be integrated using the fNIRS-EEG bimodal detection technique. However, the combined use of fNIRS-EEG focuses only on the detection of brain function and lacks regulatory effects. Repeated transcranial magnetic stimulation (rTMS) is a physical therapy technology that affects nerve functions by acting on different brain regions through a time-varying magnetic field to change the excitability of stimulated local and distant parts, has the advantages of being noninvasive, simple to operate, high in safety and the like, and is widely applied to the treatment of various neuropsychiatric diseases. Therefore, the combination of the three modes of the rTMS-fNIRS-EEG not only gives consideration to the spatial and temporal resolution of brain function detection, but also gives safe and effective feedback regulation and control, and has huge application prospect.
The combined use of EEG, fNIRS and TMS is a trend in brain imaging. By combining EEG, fNIRS and TMS, the stimulation part and stimulation conduction of TMS can be measured in real time, the stimulation effect can be known, the position, time and mode of the brain can be optimized, and the method has good application prospect in the fields of motor rehabilitation and treatment of neurological diseases.
The system combination of the rTMS-fNIRS-EEG is realized on the level of a physical structure and a digital signal, and the performance of the trimodal combination technology is improved. In the physical structure combination layer, a photoelectric combined probe cap is manufactured by a specially-made cloth cap substrate and a probe clamp to fix a multichannel fNIRS probe and an EEG electrode together, so that a 64-channel fNIRS and EEG test scheme covering the whole brain is realized. On the signal synchronization aspect, the mode of using the photoelectricity to beat the mark realizes that the signal of high accuracy is synchronous to be triggered, and the interconnect integration between a plurality of probes is very troublesome, is not convenient for carry out the dismouting change.
