Description
Technical field
This utility model relates to a kind of armarium, specifically a kind of brain electricity cap measuring EEG signals.
Background technology
Brain electricity is just being widely used in medical field and field of scientific study as a kind of important physiological signal.The gatherer process of brain electricity is generally first by brain electricity cap, electrode is fixed on scalp surface, is then measured by eeg signal acquisition, treatment facility.In this course, can brain electricity cap play pivotal role for collect EEG signals easily and accurately foremost as system.
The brain electricity cap used clinically is at present divided into two kinds substantially: one is elastic adhesive tape netted brain electricity cap, general employing bridge-type electrode, bridge-type electrode to be steeped in certain density saline solution before using, under needing medical personnel each bridge-type electrode to be clipped in separately brain electricity cap during use.Adopt this brain electricity cap to be just difficult to electrode accurately to locate, the operate miss that inevasible introducing is certain, thus affect the EEG signals quality collected.And owing to adopting metal electrode directly by the modes of emplacement be pressed on scalp, long-time measurement has strong constriction, causes the discomfort of experimenter.
Another kind of brain electricity cap is the brain electricity cap adopting hollow edged electrode, needs each electrode injection conductive paste before using, and conductive paste flow in hair gap and realizes contacting with scalp.Because each hollow edged electrode is fixed on brain electricity cap in advance, therefore site error can be avoided, but excessive conductive paste can flow on scalp, cause short circuit or measurement error, the conductive paste of thickness also can cause the dislike of patient, clear up all hollow edged electrodes again after each use, use procedure is very inconvenient.
Utility model content
This utility model provides a kind of wireless brain electricity cap based on conductive rubber material, this utility model solves existing brain electricity cap to be needed each electrode injection conductive paste, conductive paste can flow on scalp, cause short circuit or measurement error, the conductive paste of thickness also can cause the dislike of patient, and uses the problems such as inconvenience.
A kind of EEG measuring or research electrode cap are provided, this electrode cap is adopted not need to tonsure and preserved skin to measured, the rubber electrode be attached on brain electricity cap just directly can extend in measured's hair contact with scalp without the need to smearing conductive paste, the brain electric information of extraction measured.
For solving the problem, this utility model adopts following technical scheme: a kind of wireless brain electricity cap based on conductive rubber material, is characterized in that, be made up of rubber electrode, elastic support, reference electrode and wireless module; Elastic support is made up of the main support of circular arc and assistant support, and about main support, end outside is fixed with wireless module; In the middle part of main support, be provided with five assistant supports, assistant support centre position is connected with main support; Assistant support front and back end is fixed with rubber electrode; Rubber electrode connects wireless module by wire, and wireless module connects reference electrode.
Described rubber electrode is spherical.Elastic support cross section is circular.Two wireless modules are arranged at main support both sides respectively.
Electrode is fixed in electrode cap by the brain electricity cap that the utility model proposes, and accurately can carry out positioning of electrode, without the need to using conductive paste in use procedure, easy to use.Have employed rubber electrode technology and can ensure quick, efficient, the comfortable measurement carrying out brain electricity.

Detailed description of the invention
By best embodiment, this utility model is described in detail below.
As Figure 1-4, based on a wireless brain electricity cap for conductive rubber material, be made up of rubber electrode 1, elastic support 2, reference electrode 3 and wireless module 4, rubber electrode front end has dentalation, can be deep in hair with scalp close contact, there is snap-fastener rear end.Elastic support 2 is made up of the main support 2-1 of circular arc and assistant support 2-2, and main support 2-1 and number of people top size, profile are substantially identical, and main support about 2-1 holds outside to be fixed with wireless module 4.In the middle part of main support 2-1, be provided with five assistant support 2-2, assistant support 2-2 centre position is connected with main support 2-1.Assistant support 2-2 front and back end is fixed with rubber electrode 1, and five assistant support 2-2 wherein have two longer dimensions, and three sizes are shorter, and the radian of assistant support is substantially identical with number of people radian.Rubber electrode 1 connects wireless module 4 by wire, and wireless module 4 connects reference electrode 3.
Rubber electrode adopts metal-doped conductive rubber to make, and leading portion adopts dentalation, can be deep into dense hair inside and contact with scalp, and have good pliability, can reduce the sense of discomfort measured for a long time.And adopt the structure of Multilayer-tooth array to increase contact area, thus reduce contact impedance.
Elastic support adopts elasticity good conductive metal and plastics to make, and adopts the design of laminating human brain curve, can adapt to the size of majority's brain, and its open structure can facilitate the electrode of medical personnel to loose contact to adjust.Be fixed on elastic support according to the electrode position of 10-20 international standard, by wire, snap-fastener be connected with wireless module, the EEG signals collected is sent to brain electric treatment equipment.
During use, first rubber electrode is placed in Nacl solution for subsequent use, by snap-fastener, described rubber electrode is buckled on elastic support during brain wave acquisition, allow subject wears go up this equipment, described elastic support possesses good elasticity, therefore rubber electrode can be fixed on human brain appropriate location.Adjust individual electrode position and angle again, make rubber electrode be deep in the middle of hair and scalp close contact.Described reference electrode is generally placed in the place of bone projection after ear.Open the EEG signals that wireless device reception wireless module emits, measure, and adjust according to the electrode of conduction situation to loose contact.
Containing battery, Signal reception and radiating circuit in wireless module in the present embodiment, the EEG signals collected can be transmitted to brain electricity subsequent processing device.Owing to adopting the mode of wireless mode to transmit, just can be convenient to use a brain electricity equipment and multiple experimenter wearing electrode cap be measured simultaneously.
Last it is noted that obviously, above-described embodiment is only for this utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
