Embodiment
Refer to Fig. 1 and Fig. 2, the utility model discloses a kind of ear acupoint detector, comprise ear probe 1, measurement electrode 2 and measuring unit, wherein:
Shown in figure 1, ear probe 1 comprises ear mold 11 and a plurality of exciting electrode 12, and exciting electrode 12 is located on ear mold 11 and is corresponding with ear acupuncture point respectively.
Independent of one another in order to realize the measurement branch road at each exciting electrode 12 places, ear mold 11 should adopt insulant to make.In order to guarantee ear mold 11 and people's ear close contact, the shape of ear mold 11 should adapt with people's ear shape (shape of ear nest and auricle).Ear mold 11 can be designed to Multiple Type according to the size of ear, for different users; Also can carry out personalized customization according to user's ear shape.
Exciting electrode 12 adopts conductive material to make.The concrete shape of exciting electrode 12 can be foil, metal salient point etc., as long as can meet itself and ear acupoint position close contact, this utility model is not specifically limited.The quantity of exciting electrode 12 can be 32 or 64, also can set other quantity according to practical situation, and in the present embodiment, the quantity of exciting electrode 12 is 64.
Coordinate shown in Fig. 2 and Fig. 3, measuring unit comprises gating module 31, control module 32, detection module 33, display module 34 and power module 35, wherein:
Gating module 31 has a plurality of signal output parts, and each signal output part connects an exciting electrode 12 and forms a measurement branch road.In the present embodiment, gating module 31 adopts EPM240T programmable logic chips, its have 64 signal output parts (YO, Y1 ... Y63), its GND terminals ground connection, its VCC terminals connect the outfan of power module 35.
Control module 32 outputs a control signal to gating module 31 and controls one by one the conducting that each measures branch road, when a certain measurement branch road conducting, gating module 31 applies a high level to the exciting electrode 12 of this measurement branch road, is applied on the corresponding ear acupoint of this measurement branch road.In the present embodiment, control module 32 adopts PA7467 single-chip microcomputer, and signal output part I0A9, the I0A10 of single-chip microcomputer, I0A11, I0A11, I0A12, I0A13 are connected with signal input part S0, S1, S2, S3, S4, the S5 of gating module 31 respectively.
The signal input part of detection module 33 is connected with measurement electrode 2, and the signal output part of detection module 33 is connected with control module 32.In the present embodiment, the input input of detection module 33 connects measurement electrode 2 and gathers the voltage signal in measurement electrode 2, and this voltage signal is transported to control module 32 by output port AD1, AD2 and carries out analyzing and processing after second amplifying circuit amplifies.
Being connected with control module 32 of display module 34, and testing result is shown.In the present embodiment, display module 34 adopts TC1602 LCD MODULE 34, and signal input part VO, the RS of display module 34, R/W, E, D0, D1, D2, D3, D4, D5, D6, D7 be signal output part I0A0, I0A1, I0A2, I0B0, I0B1, I0B2, I0B3, I0B4, I0B5, I0B6, the I0B7 of link control module 32 respectively.
Power module 35 is gating module 31, control module 32 and display module 34 power supplies.In the present embodiment, detection module 33 output 5V DC voltages.
Operation principle of the present utility model is as follows:
During use, ear probe 1 is fixed on ear, and guarantee exciting electrode 12 and ear close contact, other positions of measurement electrode 2 and human body are contacted and (conventionally select the human body near ear, as face), exciting electrode 12, ear resistance to be measured and measurement electrode 2 have just formed a measuring circuit like this.
Control module 32 is controlled gating module 31 each exciting electrode 12 is applied to high level one by one, when a certain exciting electrode 12 is applied to high level, accordingly, on measuring circuit, will produce a voltage drop, testing circuit gathers the voltage signal on measuring circuit and sends to single-chip microcomputer and carries out analyzing and processing.Because the resistance of acupuncture point Dian Hefei acupuncture point point is different, the voltage drop producing on measuring circuit is also just different, therefore can be by judging Dian Hefei acupuncture point, acupuncture point point after single-chip microcomputer analyzing and processing; Because the ear resistance that diseased organ is corresponding is different from normal ear resistance, the voltage drop producing on measuring circuit is also just different, therefore can whether pathological changes occur by judging the organ that the ear acupoint is corresponding after single-chip microcomputer analyzing and processing.
By above description, can find out, this utility model is by arranging ear probe, realized in electrical contact with each ear resistance, each ear resistance is in parallel and independent of one another, by measuring unit, controls the conducting one by one that each measures branch road, thereby has realized automatically detecting one by one the ear acupoint, without manually selecting cave, improve the efficiency that the ear acupoint detects, avoided the error of manually selecting cave to bring simultaneously, improved the accuracy that the ear acupoint detects.
The above; it is only the preferably specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
