The front view (a) of described wear-type positioning cap, left surface view (b) and top view (c) is contained in Fig. 4.
Described wear-type positioning cap mainly comprises: hemispherical cap body 41, sponge slot 42 and employing lower jaw frenulum 43.
The cap body 41 of described wear-type positioning cap can adopt elastic weaving to be spliced, and respectively there is a rubber locating shaft 411 and 412 its rear and front end, and front end projection corresponds to the nasion, and rear end projection corresponds to occipital protuberance; Described positioning cap each side have a connection annulus 413 and 414, for being fastened on head by Velcro.As shown in Figs. 4 a-b, the front end of cap body, stretch out a length from FPz position to nasion position (Nz) along head sagittal plane and be S and adopt the locating shaft 411 that elastomeric material is made, its end is nasion position (Nz).In cap body rear end, stretch out a length from Oz position along sagittal plane to occipital protuberance position (Lz) and be S and adopt the locating shaft 412 that elastomeric material is made, its end is occipital protuberance position (Lz).Described wear-type positioning cap can be different according to human engineering design data size; Exemplary, for 60-64cm size medicated cap, locating shaft length is about 3.5156 centimetres, is that the nasion is to 20% of occipital protuberance range.
The connection annulus 413 of the left and right sides corresponding two to be picked up the ears leading edge respectively with 414.User is when locating, and only need adjust medicated cap, make front end anchor point be placed in the nasion, rear end anchor point is placed in occipital protuberance, and left and right connects annulus and corresponding two to pick up the ears leading edge respectively, can complete correctly wearing of cap body; Afterwards both sides lower jaw frenulum 43 is linked together by Velcro, just can ensure the laminating of electrode and scalp surface.Described lower jaw frenulum 43 can be elastic weaving material equally, is connected with cap body by connecting annulus.During use, the lower jaw frenulum of both sides can be linked together by the Velcro on surface.
Described wear-type positioning cap centered by F3 and the F4 position of international brain electricity 10-20 system, fixed placement two pieces of semi-enclosed sponges covers, electrode can freely insert and extract in sponges cover, and tight; Also plug type wire can be set, interface on medicated cap top, perpendicular to the horizontal plane of rubber blanket.According to international brain electricity 10-20 system, the back of the body lateral prefrontal of the corresponding brain of F3 and F4 electrode position, the quantitative relation between F3 and F4 and anchor point sees below detail parameters explanation.
Electrode can be round rubber, and corresponding sponge slot 42 is also circular, and end face is sewn on medicated cap, and bottom surface adopts semi open model, and round rubber electrode can insert and be fitted in sponge slot 43.The central point of sponge slot 43 is positioned at F3 and F4 place.There is the electrical wire interface perpendicular to head surface on the top of sponge slot 43, and the electric wire from constant0current generator can insert in this electrical wire interface.
In addition, in Fig. 4 a-Fig. 4 c, the detail parameters of Main Reference Numerals is described as follows:
Nz: nasion position (nasion anchor point); Lz: occipital protuberance position (occipital protuberance position anchor point); Cz: be positioned at middle position, the crown is the central point of nasion anchor point and occipital protuberance anchor point line, is also the central point that left and right connects annulus line simultaneously; FPz: along Nz-Lz direction, measure 20% point of Nz-Lz distance from Nz, this is FPz; Oz: along Lz-Nz direction, measure 20% point of Nz-Lz distance from Lz, this is Oz; Fz: along Nz-Lz direction, measure 60% point of Nz-Lz distance from Nz, this is Fz.
Major technique sizing specification (for 60-64cm size medicated cap) in figure.The length of rear and front end locating shaft is 3.5156cm, is that the distance of the central point distance FPz of 7.6172cm, F3 and F4 coronalplane cambered surface is 4.5411cm through the cambered surface radius R of the coronalplane of F3 and F4 point; The cambered surface radius R that left and right connects annulus and crown central point composition is 10cm (see accompanying drawing 4a).FPz and Oz is 19.6885cm along the distance of sagittal cambered surface, measures 60% of range from the nasion to occipital bone anchor point, is designated as Fz point, and this distance of cambered surface to central point, crown Cz is 6.2684cm (see accompanying drawing 4b).The vertical dimension of F3 position and F4 positional distance sagittal plane is 5.1925cm, and the diameter through the coronal plane of F3 and F4 is 7.1114cm, and the diameter through the coronal plane of Oz and FPz is 9.8496cm (see accompanying drawing 4c).
In order to the portable effectiveness through cranium galvanic stimulation system for giving up smoking that the embodiment of the present invention provides is described, carry out demonstration test.Have 14 smokers in this test to participate in, experimenter take part in two-wheeled experiment, being respectively LaRc condition (wears provided by the invention portable through cranium galvanic stimulation system for what give up smoking, i.e. negative pole condition on the right side of the positive pole of left side, current intensity 1mA) and SHAM condition (i.e. false incentive condition, electrode wearing mode is with LaRc condition, but current intensity is 0mA), the order of experiment condition balances at tested.Under two conditions, electrode is all placed on F3 and F4 position.After the LaRc galvanism of 30 minutes and SHAM galvanism, experimenter reports oneself and craves for level for medicated cigarette, and they complete the experimental duties of the smoking picture of 20 minutes subsequently, and again reports and oneself crave for level for medicated cigarette.
As shown in figs. 5 a-b, as can be seen from Figure 5A, applying after cranium unidirectional current prefrontal lobe, the increase of the amount of craving for of smoker's Subjective Reports is less than false incentive condition to result of the test, and this result is though statistically significant.As can be seen from Figure 5B, imposing after cranium galvanic stimulation to prefrontal lobe, the list of results of smoker in attention bias task reveals the trend of rising, and main manifestations is become better for the task achievement of neutral pictures.Task achievement under galvanism condition is higher than false incentive condition, and this result is though statistically significant.These PRELIMINARY RESULTS indicate the cognitive function that really can change smoker through cranium unidirectional current, and that reduces the initiation of smoking clue craves for level.
In the embodiment of the present invention, by arranging the electrode that two panels is connected with constant current generator on positioning cap, realizing through cranium galvanic stimulation, can effectively help ES to resist craving for of smoking; And positioning cap is provided with locating shaft and fixed part can ensure the accuracy of positioning of electrode and guarantee the laminating with scalp surface, meanwhile, the cost of this positioning cap is lower, and is convenient to smoker's routine use.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
