Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing:
[0030] Such as figure 1 , 2 , 7, the present invention includes a fixed seat 2 attached to the rat head 1, an adapter 3 and a signal acquisition module 4. The fixed seat 1 is fixed on the head 1 of the rat through the through hole of the positioning handle 24 with thin screws; Connect with the EEG circuit board 25 with the impedance conversion chip 22; the other end of the EEG circuit board 25 is connected with the adapter 3 through the EEG signal lead wire 26; the optical fiber 23 passes through the EEG circuit board 25 The other end of the optical fiber 23 is connected to the rat head 1 ; the adapter 3 is connected to the signal acquisition module 4 through the adapter lead wire 34 .
[0031] Such as image 3 , 4 As shown, the positioning handle 24 is in the middle of the bottom of both sides of the fixing seat 2, and the positioning handle 24 protrudes from the cyli...

The invention discloses an electroencephalogram and near infrared spectrum combined acquisition device applied to a rat. The acquisition device comprises a fixed seat fixed on the head of the rat; protruding positioning handles are arranged at both sides of the bottom of the fixed seat; through holes are formed in the middles of the positioning handles; the positioning handles are fixed on the head of the rat by screws; a cavity of the fixed seat is filled with medical silica gel for fixing an electroencephalogram electrode and an optical fiber; the electroencephalogram electrode is connected to an adapter by impedance conversion; the optical fiber is connected to the adapter; the adapter comprises an adaption box, a near infrared transmission probe and a near infrared detection probe; a cavity of the adaption box in the adapter is filled with silica gel for fixing and coupling the optical fiber and the near infrared transmission probe as well as the near infrared detection probe; the adapter is connected with a signal acquisition module. The electroencephalogram and near infrared spectrum combined acquisition device disclosed by the invention is reasonable in structure, can be simultaneously compatible to the electroencephalogram electrode and the near infrared probes, and is small in volume and light in weight; the pressure on the head of the rat is reduced; different research requirements can be met.
Description
technical field [0001] The invention relates to the technical field of medical imaging, in particular to an EEG and near-infrared spectrum combined acquisition device. Background technique [0002] Near-Infrared Spectroscopy (Near-Infrared Spectroscopy, NIRS) is a new brain detection technology that came out in the 1990s. It provides humans with an effective new method for understanding the mysteries of the brain and diagnosing brain diseases. As a non-destructive, high temporal and spatial resolution brain function detection technology, compared with other methods, it has the potential of multiple modeling, and it is more hopeful to make greater achievements in neurological research and clinical diagnosis of neurological diseases in the future. Progress. In the near-infrared spectrum wavelength range (650nm to 950nm), the permeability to the living body is relatively high, so it is called "the window of living organisms". In this band range, the near-infrared absorption c...
