Embodiment 1
[0028] Such as Figure 1 to Figure 2 As shown, it is a novel EEG signal acquisition implementation device consistent with this embodiment, including:
[0029] The EEG electrode sheet 6 includes a foam layer 1, a PET film layer 2, a circuit layer 3, an insulating film layer 4 and an adhesive layer 6 from bottom to top, and several collection points are arranged on the circuit layer 3, And the shape of the foam layer 1, the PET film layer 2, and the insulating film layer 4 matches the circuit layer 3, and the gel layer is arranged on the insulating film layer 4, where The position is consistent with the position of the collection point, and contacts the wearer's skin through the gel layer;
[0030] The host computer is connected to the EEG electrode 6, and stimulates or cancels the stimulation to the wearer's brain area through the EEG electrode 6, causing potential changes in the brain area, and then obtains the EEG signal through superposition technology.
[0031] Preferably...
Embodiment 2
[0037] Such as figure 2 As shown, a method for realizing a novel electroencephalogram signal acquisition according to this embodiment includes the following steps:
[0038] S1: Attach the EEG electrode sheet 6 to the wearer's skin; the EEG electrode sheet 6 is preferably the EEG electrode sheet 6 described in Embodiment 1.
[0039] S2: Stimulate or withdraw stimulation to the wearer's brain area, causing potential changes in the brain area, and then obtain EEG signals through superposition technology.
[0040] Preferably, the step S2 specifically includes:
[0041] S21: apply repeated stimulation to the wearer;
[0042] S22: superimpose and average the EEG containing ERP generated by each stimulus;
[0043] S23: extracting the superimposed ERP from the background of the EEG to obtain an EEG signal.
[0044] Event related potential (ERP) generally refers to the potential change in the brain area when a specific stimulus is applied to the sensory system or a certain part of...

Abstract
The invention discloses a novel device for achieving electroencephalogram signal collection. The novel device for achieving electroencephalogram signal collection comprises an electroencephalographicelectrode plate and an upper computer, wherein the electroencephalographic electrode plate comprises a foam layer, a PET diaphragm layer, a circuit layer, an insulating membrane layer and adhesive layers from bottom to top in sequence, a plurality of collection points are arranged on the circuit layer, the gel layers (adhesive layers) are arranged on the insulating membrane layer, positions of thegel layers (adhesive layers) coincide with those of the collection points, and through the gel layers (adhesive layers), the electroencephalographic electrode plate is in contact with skin of a wearer; and the upper computer is connected with the electroencephalographic electrode plate to acquire electroencephalogram signals. A novel method for achieving electroencephalogram signal collection isfurther disclosed. Through special product structure design, by combining an event related potential superposition technology principle and the electroencephalographic electrode plate for a newborn, the electroencephalogram signals of the newborn are stably and reliably collected. The electroencephalographic electrode plate can be worn and used by the newborn very conveniently, can be taken off from the newborn very conveniently, and does not have side effects on the skin of the newborn.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device and a method for realizing the acquisition of a novel electroencephalogram signal. Background technique [0002] The "neonatal period" mainly refers to the adaptation period when the fetus is delivered from the mother's womb to the outside world, because the functions of various organs of the newborn's body system are not yet mature during this period. Neonates have low immune function, poor body temperature regulation function, easy infection, and skin irritation. Nursing must be careful, scientific and reasonable. In addition, the newborn’s clothes should be as loose as possible, without hindering limb activities, and easy to put on and take off; since newborns usually sleep for 18 to 20 hours a day, the head dissipates heat and the skull is relatively soft, so it should be soft and comfortable if wearing a small hat. [0003] However, the commonly used EEG ...
