Touch cerebration stimulation device and fine adjustment assembly

Abstract

The invention provides a touch cerebration stimulation device and a fine adjustment assembly, relating to the technical field of touch cerebration stimulation. The fine adjustment assembly of the stimulation device comprises a base and a stand arranged on the base, an adjustment bracket arranged in parallel to the base is arranged on the stand, an adjustment block mounting seat is arranged on one end, facing to the base, of the adjustment bracket, an adjustment block for mounting a nozzle device is arranged on the adjustment block mounting seat along the direction perpendicular to the base in a sliding manner, a through first threaded hole is formed in the adjustment bracket, a second threaded hole opposite to the first threaded hole is formed in the adjustment block, and adjustment screw sequentially penetrates through the first threaded hole and the second threaded hole to rotate and realize the adjustment of the position of the adjustment block along the direction perpendicular to the base. The invention provides the touch cerebration stimulation device and the fine adjustment assembly, wherein through the fine adjustment assembly of the stimulation device, the fine adjustment of the nozzle device along the direction perpendicular to the base can be realized, and the whole adjustment precision can be enhanced.

Description

technical field [0001] The invention relates to the technical field of tactile brain activity measurement, in particular to a tactile brain activity stimulation device and a fine-tuning assembly. Background technique [0002] Functional Magnetic Resonance Imaging, or fMRI for short, is an emerging neuroimaging method. Its principle is to use magnetic resonance imaging to measure hemodynamic changes caused by neuronal activity. Due to the advantages of non-invasiveness and no radiation, fMRI has been widely used in human functional structure and brain map research in the visual, auditory, somatosensory cortex and parietal cortex since the 1990s. [0003] However, due to the lack of a high-precision tactile brain activity stimulation terminal system, the research on human brain tactile brain activity is greatly limited, and the main problem facing the high-precision tactile brain activity stimulation terminal system is the structure of the stimulation terminal in a limited spa...

AI Technical Summary

Problems solved by technology

[0005] Although the piezoelectric vibrating tactile stimulator cannot be finely adjusted according to the demand, and the adjustment accuracy is low; for the pneumatic diaphragm stimulator, the distance between the nozzle and the skin surface and the stimulating position of the few stimulators that use jet stimulation are both It is fixed and cannot be adjusted at will, and it is impossible to ensure that the distance between the nozzles and the skin is the same, so the accuracy of stimulation is low

[0006] Therefore, the position of the existing tactile brain activity stimulation device cannot be adjusted accurately, resulting in low stimulation accuracy, so it cannot meet the needs of use, and urgently needs improvement
