Background technology
Blood glucose meter can be fast and is detected blood sugar concentration easily, has become the doctor and the patient detects blood sugar, estimates the state of an illness and instructs diet and the common tool of medication.
The detection system of blood glucose meter is made of instrument and test paper, when the user detects blood sugar, according to instrument prompting test paper is inserted into earlier on the instrument, take then to refer to that blood is drawn into test paper with blood after, instrument will demonstrate user's blood glucose value.Blood sugar of the every detection of user will consume a slice test paper.
Common in the market blood glucose meter can be divided into electrochemical process test and light reflection technology test two big classes according to surveying sugared technology.
The electrochemical process test: the electronics that enzyme and glucose response produce uses electric current numeration facility again, reads the quantity of electronics, changes into readings of glucose concentration again.The advantage of electrochemical process test is that price comparison is cheap, is more accurate in a short time, and shortcoming is that detecting head is exposed in the air, is easy to be polluted, and influences test result, and long-term use error is bigger.
Light reflection technology: the intermediate (band colour substance) that the reaction by enzyme and glucose produces, use detecting device to detect the catoptrical intensity of test paper reflecting surface, with these catoptrical intensity, change into concentration of glucose, this type blood glucose meter electrode ports is built-in, can avoid polluting, accuracy is than higher.
Blood glucose meter measures whether an important techniques is accurately wherein arranged technique for temperature compensation.Enzyme is made on the test paper, because enzyme is activated, enzyme is little in the above activity change of 20 degree generally speaking, and below 20 degree, temperature more low activity is more poor.The electric current that active variation will produce with glucose response the time diminishes, thereby make the measurement result step-down, in order under different temperature, to measure blood glucose value accurately, blood glucose meter can detect the temperature of environment for use by the thermistor of inside, pass through temperature compensation algorithm, thereby make enzyme under different temperature, can both produce the electric current that is complementary with blood glucose value with blood as far as possible, and then draw correct blood glucose value, the temperature compensation of blood glucose meter that Here it is.Generally speaking the result who records under the different temperatures environment is more approaching, and it is more advanced to represent this producer's product temperature compensation technique.Clear and definite explanation is arranged in the blood glucose meter instructions, test under new environment if require the user to carry blood glucose meter, need at least 30 minutes wait blood glucose meter temperature balances.Because thermistor generally is positioned in the blood glucose meter, be subjected to the speed influence of shell and thermistor temperature sensor, so the new general requirement of environment temperature of blood glucose meter induction needs just can stablize more than 30 minutes at least, so if the temperature that deficiency of time then instrument detect is incorrect, will bring wrong temperature compensation into, error occur thereby cause measuring.
