The utility model is a kind of blood-sugar detecting instrument based on smart mobile phone; It mainly comprises smart mobile phone 1; It is different from prior art and is: said smart mobile phone 1 is connected with blood sugar signal acquisition module 3 one ends through the input end of earpiece audio module 101, and the other end of blood sugar signal acquisition module 3 is connected with blood sugar test paper module 2.
In the specific implementation; Said smart mobile phone 1 is provided with display module 102; The input end of display module 102 is connected with the output terminal of audio signal analysis module 103; The input end of audio signal analysis module 103 is connected with the output terminal of audio-frequency module 104, and the input end of audio-frequency module 104 is connected with the output terminal of earpiece audio module 101.
In the specific implementation; Be provided with signal converter 301 and signal amplifier 302 in the said blood sugar signal acquisition module 3; The output terminal of signal converter 301 is connected with the input end of earpiece audio module 101, and the input end of signal converter 301 is connected with the output terminal of signal amplifier 302.
In the specific implementation, be provided with transmission electrode 201 and biology sensor 202 in the said blood sugar test paper module 2, the output terminal of transmission electrode 201 is connected with the input end of signal amplifier 302, and the input end of transmission electrode 201 is connected with the output terminal of biology sensor 202.
The described smart mobile phone blood of this patent appearance has comprised the blood sugar test paper module, blood sugar signal acquisition module, three big hardware systems of smart mobile phone.Wherein the blood sugar test paper module comprises biology sensor and transmission electrode again; The blood sugar signal acquisition module comprises signal amplifier and signal converter again; Intelligent mobile phone system comprises earpiece audio module, audio-frequency module, audio signal analysis module and display module again.
Its concrete blood sugar detecting method is for to be inserted into the blood sugar signal acquisition module on the earphone interface of smart mobile phone, and the user starts blood sugar test software and gives the user with close friend's detection interface display on smart mobile phone.The user is inserted into the blood sugar signal acquisition module with blood sugar test paper; Then with between the blood inlet region of finger blood drop to the blood sugar test paper; The biology sensor of test paper the inside will produce chemical reaction with the sugar in the blood, produces electric current, the amplifier in this current direction blood sugar signal acquisition module; Through current conversion is voltage signal; Convert voltage signal into the low frequency sound signal again and be transferred to smart mobile phone through the Mike's interface in the earphone interface above the smart mobile phone, cell phone software carries out digital collection to the sound signal of input and is transferred to the audio signal analysis module then and obtains frequency numerical value do signal analysis, is that the transformation curve of the chip of frequency draws corresponding voltage value according to the voltage transitions in the module again; Again according to the compensation characteristic of this batch blood sugar test paper; Compensate with compensation meter, draw the blood glucose value that accuracy meets industry requirement, and blood glucose value is presented on the display screen of mobile phone.
Implementation step is:
Step 1: the sugared concentration in the blood is converted into electric signal, and the user is inserted into the blood sugar signal acquisition module on the earpiece audio module in the intelligent mobile phone system, then the blood sugar test paper module is inserted in the blood sugar signal acquisition module.The user can begin to gather finger blood; On finger blood drop 1-2 being dripped between the blood inlet region of blood sugar test paper module; Sugar in the blood will produce chemical reaction with the biology sensor in the blood sugar test paper module and produce electric signal under the catalysis of enzyme, through transmission electrode electric signal is transferred to signal amplifier then.Because there are a distinctive reaction formula in the chemical characteristic of biology sensor and electric signal, can calculate the conversion relation of blood sugar concentration and current/voltage through blood sugar chemical reaction formula.
