Description
Technical field
The utility model relates to a kind of blood glucose meter, is specifically related to a kind of high-precision intelligent blood glucose meter.
Background technology
Blood glucose meter can detect blood sugar concentration fast and easily, has become doctor and patient detects blood sugar, evaluates the state of an illness and instructs the common tool of diet and medication.The detection system of blood glucose meter is made up of instrument and test paper, when user detects blood sugar, is first inserted on instrument by test paper according to instrument prompting, and after then taking to refer to that blood is drawn into test paper by blood, instrument will demonstrate the blood glucose value of user.Current, all there is matching problem in varying degrees in blood sugar test paper and corresponding blood glucose meter.Real time temperature when one of wherein important cooperation factor to affect is exactly each measurement creates very large impact to blood glucose test results.Because the reaction enzymes of blood sugar test paper is activated, generally, reaction enzymes is more than 20 degree, and activity change is little, and below 20 degree, temperature is lower, and activity is poorer; Active variation will when reacting with blood-glucose, generation current diminishes, thus cause measurement result step-down, have a strong impact on the accuracy of blood glucose value testing result, so the accuracy in order to improve detection, need to use the technique for temperature compensation of stability and high efficiency to revise this error, thus the result measured at different temperature of the blood of the identical blood glucose value made closer to, more consistent, reach the object obtaining patient blood glucose's value more accurately.
In addition, the blood sugar test paper of different batches all also exists the difference of performance parameter due to the difference of printing, will input different parameters adjust when therefore using the blood sugar test paper of different batches to measure blood sugar concentration to blood glucose meter.Current most of blood glucose meter uses manually or coded card stores these parameters to instrument input code, the high and complicated operation of such cost.

Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, a kind of high-precision intelligent blood glucose meter, it comprises microprocessor, test strips, test interface, identification module, Signal-regulated kinase, A/D converter, temperature sensor, storer, communication module and display, described test strips is inserted in described test interface, test strips is provided with working electrode, to electrode, reference electrode and coding electrode group, test interface successively with identification module, Signal-regulated kinase, A/D converter, microprocessor is connected in series, described microprocessor is also connected to temperature sensor, storer, communication module and display, described communication module is connected to server.
The coding electrode group reflecting this examination bar correction parameter with binary coding of the present utility model, comprise multiple binary coding electrode, the number of described binary coding electrode is two or more, and binary coding electrode is connected to electrode or reference electrode with described.In use, to electrode or reference electrode ground connection, keep low level; Working electrode is for keeping duty, specific as follows: after blood sample adds, add certain positive voltage to working electrode, thus and form electrolytic environments between electrode or reference electrode, and then form electric current on the working electrode (s, and detect blood sugar concentration with the electric current on testing electrode.Coding electrode group reflects the information of the correction parameter of this examination bar with binary coding.When the number of binary coding electrode is two, comprise 2 power i.e. 4 combination possibilities of 2 altogether, each combination represents the information of a correction parameter, and namely codified goes out the information of 4 correction parameters.Identical, when the number of binary coding electrode is three, i.e. the information of codified 3 power totally 8 correction parameters of going out 2.Described identification module is used for identifying the binary coding of coding electrode group of examination bar, obtains correction parameter corresponding to described binary coding.
The utility model is when measuring blood sugar, test paper is inserted blood glucose meter, the Auto Power On of blood glucose meter meeting simultaneously, after start, blood glucose meter can pass through temperature sensor senses test paper temperature, if test paper temperature variation too fast (such as change per second is more than 2 DEG C), blood glucose meter will be waited for, until blood glucose meter test paper temperature stabilization, prompting starts measurement of bleeding.The advantage done like this is: sensor can the temperature of perception test paper, more accurately can must compensate calculating.Pass through perception test paper temperature after inserting test paper, judge whether the temperature of test paper is stablized, then determine whether measure, improve degree of stability and the reliability of blood glucose meter.
Described temperature sensor adopts unibus micro temperature sensor DS18B20, and its temperature-measuring range is-55 ~+125 DEG C, and Measurement Resolution is 0.0625 DEG C, and temperature measurement accuracy is ± 0.5 DEG C.Temperature signal is through multi-way switch input microprocessor, and microprocessor carries out the auto modification of test result error according to the temperature characterisitic of blood sugar test electrode.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
