[embodiment]
For purpose, the feature and advantage that make the utility model can be more obviously understandable, the embodiment of the utility model is done detailed explanation below in conjunction with accompanying drawing.
The present invention provides a kind of clamshell phone of tool blood flow detection function, comprises renovating and fuselage of being hinged, and is provided with main control chip in the clamshell phone, clamshell phone also comprise be located at renovate and/or fuselage on sensing unit, be used to obtain the blood flow detection signal; Main control chip is according to blood flow detection calculated signals blood flow index parameter, for example one or more in the parameters such as heart rate, cardiac output, peripheral resistance, blood vessel elasticity, blood viscosity and microcirculation situation.This sensing unit can adopt devices such as pulse transducer, photoelectricity volumetric blood flow pulse wave sensor.
Medical research shows that the red blood cell in the blood has very strong infrared ray absorbing ability.Along with beating of heart, the volumetric blood of tissue can change thereupon.When blood was delivered to tissue, its transmittance to infrared light will reduce; When blood flowed back to heart, tissue will increase the transmittance of infrared light.This phenomenon is the most obvious at positions such as finger tip, ear-lobes.Therefore, can shine above-mentioned position, detect transmitted light and convert light signal into the signal of telecommunication with the opposite side of infrared receiving tube at this position with infrared transmitting tube.This signal of telecommunication just can obtain that main control chip can discern after through amplification, filtering, shaping with the corresponding square-wave signal of heart rate.
Fig. 1 is the surface structure sketch map of the clamshell phone of tool blood flow detection function among the embodiment, and Fig. 2 is the electrical block diagram of the clamshell phone of tool blood flow detection function among the embodiment.The clamshell phone 100 of tool blood flow detection function comprise be hinged renovate 10 with fuselage 20, be provided with main control chip 40 in the clamshell phone 100 of tool blood flow detection function.The clamshell phone 100 of tool blood flow detection function also comprises:
Be located at for one in infrared emission unit 11 and the photoelectricity receiving element 21 and renovate on 10, another is located on the fuselage 20.Because traditional clamshell phone major part all is located at main control chip 40 in the fuselage 20, display unit 50 is located at and is renovated 10 surfaces.Therefore in the present embodiment photoelectricity receiving element 21 is located on the fuselage 20, infrared emission unit 11 is located at and is renovated on 10, and is as shown in Figure 1.The line distance that can shorten between photoelectricity receiving element 21 and the main control chip 40 is set like this.
Renovate when the clamshell phone 100 that infrared emission unit 11 and photoelectricity receiving element 21 are located at tool blood flow detection function respectively covers 10 with two surfaces of fuselage 20 mutual butts on.During measurement, only need finger tip is put between infrared emission unit 11 and the photoelectricity receiving element 21, under the effect of the hinge of the clamshell phone 100 of tool blood flow detection function, renovate 10 and can finger tip be clamped with fuselage 20.Along with beating of heart, the red blood cell concentration in the finger tip is the variation of generating period property also, so photoelectricity receiving element 21 can pick up the periodically variable signal of telecommunication.Therefore this signal of telecommunication is extremely faint, needs (fuselage 20 in) signalization treatment circuit 30, and the amplifying circuit that passes through high-gain amplifies, and the main control chip 40 that carries out again can making a gift to someone behind the filter shape is handled.Therefore in embodiment illustrated in fig. 2, signal processing circuit 30 comprises interconnective amplifying circuit and filtering shaping circuit.
As long as measure K the time t of cardiac cycle continuously, just can draw number (heart rate) n of heart per minute:
n＝60K/t
The relative position of infrared emission unit 11 and photoelectricity receiving element 21 will satisfy renovates 10 when opening predetermined angular, and the infrared ray direction of infrared emission unit 11 emissions is over against photoelectricity receiving element 21.Can combine the force data of hinge to make an experiment, predetermined angular is adjusted.Satisfy and to renovate 10 when opening predetermined angular, guarantee user's comfort level and ease for use as far as possible.Except finger tip shown in Figure 1 from the mode that the front is stretched into, the mode that also can adopt the side to stretch into, this moment, the position that is provided with of infrared emission unit 11 and photoelectricity receiving element 21 also needed to change.
Measure the heart rate except the employing finger tip in addition, other positions that also can use health, for example toe, ear-lobe etc. are measured, but it is convenient all to be not so good as finger tip.
In a preferred embodiment, infrared emission unit 11 is infrarede emitting diodes.This infrarede emitting diode can be a discrete device, also can make the infrarede emitting diode in the range sensor that the clamshell phone 100 of apparatus blood flow detection function carries.Photoelectricity receiving element 21 can be photoelectric receiving devices such as photodiode, phototriode, infrared receiving tube, is preferably infrared receiving tube.
The display unit 50 of the clamshell phone 100 of tool blood flow detection function is electrically connected with main control chip 40, is used for the heart rate that main control chip 40 calculates is shown.In the embodiment of clamshell phone 100 for the double screen configuration of tool blood flow detection function, display unit 50 comprises main display (Fig. 1 does not show) and secondary display screen 52.Wherein main display is located at and is renovated 10 when covering and the one side of fuselage 20 butts; Secondary display screen 52 is located at and is renovated 10 another side (the visible one side of user when promptly covering); Heart rate is presented on the secondary display screen 52, and user's testing result when measuring heart rate is visible in real time, does not need to renovate again.Secondary display screen 52 can adopt LCDs.
The clamshell phone of above-mentioned tool blood flow detection function; Only need be provided with infrared emission unit and photoelectricity receiving element (for the mobile phone that possesses infrared distance sensor can also be directly with the infrarede emitting diode of range sensor as infrared emission unit); And set up pre-process circuit in mobile phone inside and can realize; Need the surface structure of existing mobile phone not made a change, save cost and can not destroy the cell phone appearance structure.Finger tip placed to close between infrared emission unit and the photoelectricity receiving element just renovate and can detect, easy to operate.
The above embodiment has only expressed several kinds of execution modes of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
