Description
Technical field:
The utility model relates to technical field of medical appliance structures, is a kind of portable intelligent blood glucose meter specifically.
Technical background:
Diabetes are one of four big principal diseases of harm humans health, have become global health problem.The diabetes patient worldwide increases just year by year.The World Health Organization (WHO) estimates that the whole world had 1.43 hundred million diabetics approximately in 1998, and by 2025, along with population growth, aging and regional urbanization, this numeral will reach 300,000,000.China diabetic has reached 3,000 ten thousand more than, still has diabetic more than half undiscovered.
The cause of disease more complicated of diabetes, and can cause multiple complications.Because diabetic's pancreas is excreting insulin normally, makes glucose (blood sugar) concentration in the blood can not remain on normal level.Therefore must often detect blood sugar concentration,, keep the normal level of blood sugar by oral hypoglycemic medicine and an amount of insulin of injection.Thereby accurately measuring blood concentration is extremely important.Excessive and very few take medicine and insulin injection all is very disadvantageous concerning the patient.
At present, domestic and international diabetic's blood sugar test generally adopts the method for chemical detection.The each detection needs to gather more blood, exposed the shortcoming of following inherence:
(1) the big inconvenience of volume can not detect blood glucose value at any time
(2) stand bigger misery because the blood of taking is many since the wound of diabetic own just be difficult for healing when serious in addition human body fester gradually, so this detection method is very unfavorable to treatment of diabetes;
(3) limited the detection frequency of blood sugar;
(4) although it is noninvasive that glucose in urine detects, limitation is bigger, and the crowd who is lower than kidney threshold value (10mmol/L) and is higher than normal value (7mmol/L) for those blood sugar can not in time sound a warning, and testing result is not accurate enough.
People be badly in need of a kind of portable, blood sampling volume is few, blood sugar detecting method easily.Therefore, portable intelligent blood sugar test method is the inexorable trend of blood sugar test technical development, and it will make the diabetes detection means produce qualitative leap, and treatment of diabetes is had important and practical meanings.
Summary of the invention:
The purpose of this utility model: a kind of novel portable intelligence blood glucose meter is provided, its precision height, good reproducibility, accuracy rate is greater than 90%, extensively the family of suitable medical system.
The utility model solves the technical scheme that problem adopted of its technology: the utility model provides a kind of portable intelligent blood glucose meter, utilizes electrochemical method directly to measure the detecting instrument of the concentration of blood sugar in the blood.This instrument is by battery, the A/D change-over circuit, and input circuit, measuring blood concentration value interface circuit, the PC telecommunication circuit, the display part, memory circuit, hummer connect to form with one-chip computer respectively successively.Wherein battery is used for powering and guarantees the normal operation of circuit, test blood sugar part is by one-chip computer, the test piece of A/D change-over circuit, measuring blood concentration value interface circuit and measuring blood connects and composes, wherein one-chip computer, A/D change-over circuit and temperature measurement circuit are used for collecting temperature, and memory section is connected and composed by PC telecommunication circuit, memory circuit and one-chip computer; The importation is connected and composed by one-chip computer and input circuit and hummer, and the display part is connected and composed by display circuit and LCDs.
Design concept of the present utility model is according to as follows:
According to electric biochemical theory---applying certain voltage can increase along with the increase of the blood sugar concentration in the blood in the electric current that the blood after enzyme reaction produces---design.By accurately measuring these weak currents, and according to the relation of current value and blood sugar concentration, inverse goes out corresponding concentration.
Need on corresponding electrode, apply certain voltage during measuring blood, and the stability of voltage will directly influence measurement result, and therefore, consider to obtain, rather than directly from power supply, obtain from metastable reference voltage.One-chip computer A/D sampling be magnitude of voltage, and detected be the current value of trace; Thereby also need current value to be amplified and convert to the correspondent voltage value.Adopt circuit as shown in Figure 2 just can realize this requirement.Therefore adopt such circuit just can realize blood glucose measurement.
Calculate blood glucose value again after calculating electric current, determine blood glucose value at last by the relation of blood glucose value and temperature again after calculating the blood glucose value instrument.By data are carried out the cubic curve match, just can obtain the graph of relation between blood glucose value and the current value.Fig. 3 is the comparison diagram of raw data sectional curve and matched curve.Find out that easily two curves are very identical; Therefore in practical operation, can replace piecewise function with a formula.Intercept middle straight line Function Y=Ax+B wherein, X is a current value, and the μ A of unit, Y are corresponding blood glucose values, and A is the slope of test piece, and B is the intercept of test piece, and unit is mg/dl.The better CV of the measuring repeatability of blood glucose meter and blood glucose test＜3% is higher than the requirement of national standard＜7.5%.
The utility model is summarized as: the utility model relates to a kind of portable intelligent blood glucose meter.Its formation comprises one-chip computer, input circuit, display circuit, measuring blood value interface circuit, temperature measurement circuit, PC telecommunication circuit and memory circuit.Assay method and the contrast of existing electronics blood-sugar detecting instrument that traditional blood glucose meter is surveyed blood sugar concentration are that volume is big, cost is high, blood sampling volume is big, need adjust the test pieces that coefficient adapts to different parameters with password card or manual mode, bring a lot of inconvenience to the patient, can not take the detection blood sugar concentration at any time with oneself, and high general home-usely do not rise of cost, blood sampling volume be greatly we more than several times.The utility model has the advantages that cost is low, portable, take blood volume few (only needing 1.5 μ l), be with memory function (can store 180 records), can communicate by letter with PC and can download the record of all measurements at any time, and Based Intelligent Control does not need to transfer coefficient to come the adaptive testing sheet with the password card, and it is a lot of to be easy to use like this.By Computer Analysis, comparison, processing, directly show the chaff content in the blood, measuring blood concentration value precision height, good reproducibility, extensively suitable medical system and family.
The beneficial effect that the utility model produced: a kind of novel portable intelligence blood glucose meter is provided, its precision height, good reproducibility, accuracy rate is greater than 90%, extensively the family of suitable medical system.
