Fig. 1 a～1d is the external structure schematic diagram of portable electrocardiosignal measuring device all angles in an embodiment.This portable electrocardiosignal measuring device is card form structure, and device body 10 is provided with inside body electrode, comprises side electrode sheet 22 and front electrode sheet 24.Side electrode sheet 22 is located at a short side of apparatus main body 10.Front electrode sheet 24 is located at second half the front that apparatus main body 10 does not arrange side electrode sheet 22.For the portable electrocardiosignal measuring device that is equipped with display screen 30, the one side that is provided with display screen 30 is refered in particular in front.Side electrode sheet 22 and front electrode sheet 24 one of them positive input electrode as electrocardio measuring circuit, another is as the negative input electrode of electrocardio measuring circuit.
Above-mentioned portable electrocardiosignal measuring device, the hand thumb of user is pressed the back of front electrode sheet 24, right hand forefinger picking-up device main body 10, forms the gripping to apparatus main body 10.Side electrode sheet 22 is as multifunction electric pole piece, both can use left index finger to press measures, also after can apparatus main body 10 being held with a firm grip with the right hand, side electrode sheet 22 is carried out to electrocardio measurement by being pressed in chest, abdominal part or shank, therefore can carry out easily hand-held measurement, comprise that between hands hands, hands breast or hands lower limb etc., electrocardio is measured.The human body contacting due to the front electrode sheet 24 on the side electrode sheet 22 by with left side and right side supports portable electrocardiosignal measuring device, and right one side of something of therefore front electrode sheet 24 being located to apparatus main body 10 can make user hold more surely.
The purpose of design of front electrode sheet 24 is the thumb contact with the right hand, is therefore designed to the shape that can fully contact with thumb, and its orthographic projection can be the circle shown in Fig. 1, or the ellipse shown in Fig. 2, racetrack.Therein in an embodiment, the structure that front electrode sheet 24 is designed to cave inward, thus coordinate with the finger belly of thumb.In other embodiments, front electrode sheet 24 can be also evagination or planar structure.
Please refer to Fig. 1, the purpose of design of side electrode sheet 22 is that left index finger is measured by being pressed in equipment side face, or electrocardio measurement is carried out to by positions such as being pressed in chest, abdominal part, shank in side, therefore only need to guarantee good contact, should side electrode sheet 22 not designed too greatly, for example, should not extend to the drift angle of apparatus main body 10, as shown in the embodiment of Fig. 1, to avoid local unnecessary contacting, the accuracy that impact is measured of occurring of side electrode sheet 22 and other.Certainly, user also can contact, measure with side electrode sheet 22 with other finger of left hand.Understandable, the cost of inside body electrode is wanted ratio device body (being generally plastics) height, and the size of controlling side electrode sheet 22 while therefore designing can also reduce cost.
In the embodiment shown in fig. 1, inside body electrode also comprises the back electrode sheet 26 of being located at apparatus main body 10 back sides.The relative position of back electrode sheet 26 and front electrode sheet 24 should just in time adapt to the holding mode of hand thumb forefinger, for example be located at front electrode sheet 24 under, the posture that the right hand of being convenient to user supports backplate sheet 26 (by holding or forefinger front pinches forefinger side) with thumb press front electrode sheet 24, forefinger grips.
Fig. 3 is the circuit connection diagram of an embodiment center electrical measurement circuit 40 and inside body electrode, and Fig. 4 is the circuit connection diagram of another embodiment center electrical measurement circuit 40 and inside body electrode.In the embodiment shown in fig. 3, back electrode sheet 26, as the output of the driven-right-leg circuit of electrocardio measuring circuit 40, has improved the capacity of resisting disturbance that electrocardio picks up.In the embodiment shown in fig. 4, back electrode sheet 26 directly with front electrode sheet 24 short circuits, thereby increase the equivalent contact area of pointing, to obtain better signal quality.
Refer to Fig. 1 b, portable electrocardiosignal measuring device also comprises outside ecg cable plug interface 52.User can be plugged on the plug of the outside ecg cable of electrocardio on outside ecg cable plug interface 52, uses external electrode slice 53 and electrode slice 55 to measure (referring to Fig. 5, Fig. 6).Use outside ecg cable to measure, can guarantee under some application circumstances, for example winter or user hand measure ecg wave form accurately when relatively drier.
Refer to Fig. 5, Fig. 6, portable electrocardiosignal measuring device also comprises outside ecg cable plug automatic identification circuit 56 and analog switch 58.Outside ecg cable plug automatic identification circuit 56 is for when outside ecg cable plug interface 52 being detected and have plug to insert, and control simulation switch 58 is the disconnection that is electrically connected to electrocardio measuring circuit 40 by inside body electrode.Concrete, in the embodiment shown in fig. 5, analog switch 58 has two states: inside body electrode is connected to be connected (outside ecg cable of while plugs automatic identification circuit 56 outside ecg cable is connected with electrocardio measuring circuit 40) of breaking inner body electrode and electrocardio measuring circuit 40 when externally ecg cable inserts when inserting without outside ecg cable with electrocardio measuring circuit 40.In the embodiment shown in fig. 6, analog switch 58 also has two states: when inserting without outside ecg cable, inside body electrode is connected with electrocardio measuring circuit 40, when externally ecg cable inserts, it is connected to (being equivalent to single-pole double throw) with electrocardio measuring circuit 40.
After recognition of devices is inserted to outside ecg cable, by being connected of analog switch 58 breaking inner body electrodes and electrocardio measuring circuit 40, automatically switch to outside ecg cable and carry out electrocardio measurement, in the time of can avoiding testing, be subject to interference and the impact of inside body electrode.
In an embodiment, electrode surface is electroplated silver chloride and is processed, and can realize good contact skin and lower polarizing voltage, thereby improve the waveform quality of electrocardiosignal therein.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
