1. An assembled, downward-pressing, multifunctional electroencephalogram (EEG) cap, at least comprising:
a cap body, configured to be worn on a head of a patient, and formed by a plurality of constituent blocks,
wherein each of the constituent blocks comprises a first unit and a second unit that carry extracranial electrodes for detecting EEG signals from corresponding areas of the head of the patient, in which the first unit and the second unit are configured to perform relative movements and thereby change their relative positions, and
wherein the constituent blocks comprise snap-in connectors:
the EEG cap being characterized in:
for each of the constituent blocks, the first unit and the second unit being shaped to fit a curved surface of the head of the patient; and
the first unit of the constituent block being movably connected to the second unit by means of a drive system provided between at least a part of the first unit and a part of the second unit,
wherein the extracranial electrodes located on the first unit and on the second unit are configured to at least follow the relative movements between the first unit and the second unit in a first direction so as to move toward and/or away from an EEG measuring area on the head of the patient,
wherein the constituent blocks with snap-in connectors are movably connected with adjacent constituent blocks also provided with snap-in connectors by their respective snap-in connectors, so as to form the cap body and so that when the cap body is put on the head of the patient, a distance between the adjacent constituent blocks is able to increase or decrease in a second direction within a limited range so as to accommodate different sizes of heads of patients while the constituent blocks are allowed to move in the first direction,
wherein each snap-in connector is configured as a combination of a sliding block and a sliding chute, wherein the sliding block is provided with an extension component that is configured to extend or retract within a limited range, and the sliding block of one constituent block and the sliding chute provided on an adjacent constituent block are configured to engage with and positionally restrict each other, so that the constituent blocks under limited movable positional restriction of the extension component, are able to increase or decrease the distance between the adjacent constituent blocks in the second direction in the limited range to accommodate the different sizes of the heads of the patients, and to slide in the first direction along a sliding path defined by the sliding block and the sliding chute that are arranged along the first direction.
