Description
Technical field
The utility model relates to technical field of medical appliance structures, is a kind of blood glucose meter specifically.
Background technology
Diabetes are one of four large principal diseases of harm humans health, and its symptom main manifestations is the abnormal of glucose content in blood and urine.Estimate that according to the World Health Organization (WHO) (WHO) and IDF (IDF) diabetic will from 1.35 hundred million people of nineteen ninety-five, grow to 300,000,000 people of 2025.Modern medicine research is found, no matter is insulin-dependent diabetes mellitus (IDDM) or type II diabetes, and blood sugar is carried out the generation that good control can reduce diabetic complication.
because blood concentration can produce considerable influence to blood glucose measurement, and cause the larger error of measurement result, therefore in order to access blood sugar concentration testing result more accurately, just must consider simultaneously the impact of blood concentration, but the detection blood sugar concentration that traditional blood glucose meter can only be simple, do not consider that different blood concentrations are on the impact of blood glucose measurement result, therefore, blood concentration is combined with blood glucose measurement, the intelligent blood glucose meter that analysis-by-synthesis detects is the inevitable development trend of blood sugar test instrument, the intelligent blood glucose meter that can obtain accurate blood sugar concentration has important practical significance to the treatment of diabetes.
Summary of the invention
The present invention is directed in present blood glucose meter research and development and do not consider that blood concentration affects the blood sugar test result, cause the larger problem of blood sugar test resultant error, a kind of blood glucose meter is provided, comprise housing, and be installed on the interior surface-mounted integrated circuit of housing, offer display window and blood sugar test paper insert port on described housing; Be integrated with signal acquisition circuit, signal processing circuit and microprocessor on described surface-mounted integrated circuit, described signal processing circuit comprises blood sugar signal processing circuit and blood concentration signal processing circuit; Described signal acquisition circuit is connected with the blood sugar test paper access port, and described microprocessor is connected with display window, and described signal processing circuit is connected with microprocessor with signal acquisition circuit respectively.
After blood and blood sugar test paper generation enzyme reaction, by signal acquisition circuit, signal is passed to signal processing circuit, and in blood sugar signal processing circuit and blood concentration signal processing circuit in signal processing circuit, carry out respectively the calculating of blood sugar concentration detection and electric signal climbing speed, thereby obtain respectively blood sugar concentration data and blood concentration data, two data are processed by microprocessor analysis, according to different blood concentration values, blood sugar concentration is proofreaied and correct, and and then will be accurately blood sugar concentration be presented on display window.
Certainly this display window can be understood as the display screen of blood glucose meter for common blood glucose meter.
Further, the utility model discloses the extraction electrode that described signal acquisition circuit is blood sugar test paper.Signal processing circuit is connected with the extraction electrode of blood sugar test paper.
In sum, after adopting technical scheme disclosed in the utility model, can carry out intelligent decision for different blood concentrations, automatically adapt to and revise blood sugar test result under different blood concentrations, thereby improve the accuracy that blood sugar concentration detects data.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.Need to prove, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in width figure, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometric center.
Embodiment 1
As shown in fig. 1, a kind of blood glucose meter comprises housing, and is installed on the surface-mounted integrated circuit in housing, offers display window and blood sugar test paper insert port on described housing; Be integrated with signal acquisition circuit 1, signal processing circuit 2 and microprocessor 3 on described surface-mounted integrated circuit, described signal processing circuit 2 comprises blood sugar signal processing circuit 21 and blood concentration signal processing circuit 22; Described signal acquisition circuit 1 is connected with the blood sugar test paper access port, and described microprocessor 3 is connected with display window 5, and described signal processing circuit 2 is connected with microprocessor with signal acquisition circuit 1 respectively and is connected.
Further, in the present embodiment, described signal acquisition circuit 1 is the extraction electrode of blood sugar test paper 4.
During use, concrete data flow is with reference to shown in figure 2, drop of blood enter blood sugar test paper 4 and with its generation enzyme reaction, apply specific voltage in reacted blood, thereby produce the enzyme reaction electric signal.This signal is by the extraction electrode in blood sugar test paper, namely signal acquisition circuit 1 is sent into signal processing circuit 2,22 pairs of signal samplings of blood concentration signal processing circuit in signal processing circuit 2 and analysis obtain electric signal climbing speed data, electric signal climbing speed data enter microprocessor 3, by calculating the blood concentration by the detected drop of blood of climbing speed judgement of signal; Simultaneously, 21 pairs of enzyme reaction electric signal of blood sugar signal processing circuit are processed, and blood glucose level data is transferred to microprocessor 3, microprocessor 3 is in conjunction with the blood concentration data,, correspondingly adjust and participate in the parameter that blood sugar concentration is calculated, and calculate final blood sugar concentration, send data to display window 5, thereby the blood sugar test result is reflected on display screen accurately.
For more detailed explanation blood concentration and the relation between the electric signal climbing speed, done in the present embodiment further relationship model explanation.With reference to figure 3, it is enzyme reaction electric signal sampling schematic diagram.Horizontal ordinate is the time, and ordinate is signal amplitude.In the signal sampling process, suppose that sample frequency is f, sampling period T=1/f, the maximal value of supposing enzyme reaction electric signal curve is a, and the first sampling point value is b, and single-chip microcomputer obtains sampling number N when obtaining maximal value a.Hence one can see that: curve rise time t=N * (1/f)=N * T, according to more than, can obtain its climbing speed K:
K=(a-b)/t
Formula can be found out thus, and the time is shorter, and the climbing speed slope of a curve of enzyme reaction electric signal is larger, shows that blood concentration is higher.
The above is embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
