The present invention relates to a control method of a glucose and blood glucose meter for providing a urine glucose measuring function to measure the concentration of sugar in the blood to selectively measure the urine and blood glucose with a single meter.

In general, blood glucose measurement is a blood glucose measurement at the fingertips, urine glucose measurement is a measure of the sugar contained in urine, urine glucose measurement is a simple way to measure glucose in the urine without taking blood, but accuracy While falling, the blood glucose measurement is determined, and the concentration must be measured at regular intervals to accurately determine the progress of diabetes.

However, in the related art, only a blood glucose meter is commercialized, and when a patient purchases it and periodically checks the progress of the disease, there is a problem in that the patient has to take a blood every time the measurement is performed. Since it is necessary to discriminate with the eye, there is a problem in that it is difficult to accurately determine the progress of diabetes due to the error in the temperature measurement of sugar.

Accordingly, an object of the present invention is to provide a control method of a glucose and blood glucose meter to selectively measure the urine glucose and blood sugar with one measuring device.

Another object of the present invention is to provide a control method of a glucose and blood glucose meter that enables patients who require periodic measurement to easily measure the concentration of sugar without the inconvenience of having to collect blood every time, and accurately determine the progress of diabetes. have.

The control method of the present invention having the above object is to drop the liquid to be measured on the test paper per test and delay the predetermined time by turning on the measurement start key, and then operate the optical sensor unit to reflect the degree of discoloration of the test paper for the liquid The intensity of the signal is detected, and the signal is amplified and converted into a digital signal.

Then, the measurement mode is determined by checking the state of the blood glucose / urea glucose selector switch, and the glucose concentration is calculated from the blood glucose and urine glucose data tables set in the measurement mode between the determinations, and the value is displayed and stored. .

In particular, the present invention can selectively measure glucose and type sugar, so in the case of patients requiring periodic measurement, glucose measurement is simple, without the need to collect blood by urine glucose measurement, and if there is a large difference from the previous measured blood sugar again Measurements can be made available to patients by measuring the exact blood glucose level.

Hereinafter, with reference to the accompanying drawings will be described in detail the control method of the glucose and blood glucose meter of the present invention having the above objects and features as follows.

1 is a circuit diagram of a glucose and blood glucose meter to which the control method of the present invention is applied. As shown in FIG. 1, a microcomputer 100 having a timer 101 and a memory 102 and controlling the overall operation of sugar concentration measurement is shown. And a microcomputer peripheral circuit 110 including a constant voltage circuit for supplying operating power, a reset circuit for resetting the microcomputer 100 to an initial state, an oscillation circuit for supplying a clock signal to the microcomputer 100, and a blood sugar / urea sugar Selective switch is composed of various operation name link keys such as measurement start key and the like to input an operation command to the microcomputer (120), and an alarm unit for alerting the measurer to perform the following operation under the control of the microcomputer ( 130, an optical sensor unit 140 that emits light to the glucose measurement test sheet under the control of the microcomputer 100, and detects the reflected light, and an amplifier 150 that amplifies the output signal of the optical sensor unit 140. And an output signal of the amplifier l50 The analog / digital converter 160 converts the digital signal into a digital signal and inputs it to the microcomputer 100, and the display unit 170 displaying the sugar concentration under the control of the microcomputer 100. FIG. 2 is a signal flow diagram illustrating a control method of a glucose measuring apparatus of the present invention.

In the control method of the present invention, when the measurer selects the measurement mode by switching the blood sugar / urea glucose selector switch of the keyboard unit 120, the reset circuit in the microcomputer peripheral circuit 110 is operated at the initial time of supplying the power supply. In step 201, the microcomputer 100 performs an initialization operation. In operation 202, the microcomputer 100 determines whether the measurement start key of the keyboard unit 120 is turned on.

In this state, if the measurer drops blood or urine to measure blood glucose value or urine glucose value on the glucose measurement test paper and turns on the measurement start key, the microcomputer 100 sets a preset reaction time in step 203. Then, the reaction time set in step 204 is counted by the timer 101.

In step 205, the glucose test paper determines whether a certain reaction time has elapsed to react with blood or urinary sugar. If the test paper reaction is not completed, the test paper is repeatedly performed from step 204 to continuously count the time. When the time elapses, the alarm unit 130 is operated in step 206 to inform the measurer that the reaction is completed and to instruct the wipe of the remaining liquid on the test paper, and in step 207, the discoloration time of the test paper is counted by the timer 101. In step 208, it is determined whether the color change time has elapsed.

If the discoloration time has not elapsed, the process is repeated from step 207 to continue counting the time, and when the discoloration time of the test paper has elapsed, the test paper is inserted into the measurement chamber in step 209.

When the test paper is inserted, the microcomputer 100 operates the optical sensor unit 140 in step 210 to emit light to the glucose measurement test paper, and when the light is incident, the glucose measurement test paper is applied to the concentration of the sugar contained in the blood or urine. The light is reflected according to the discolored state, and thus the reflected light is detected. The detected light is amplified to a certain level by the amplifier 150 and converted into a digital signal by the analog / digital converter 160. In step 211, the measurement data converted by the analog-to-digital converter 160 is input to the microcomputer 100, and in step 212, the microcomputer 100 checks the state of the blood sugar / urea glucose selector switch to determine whether blood glucose is measured. Determine if it is a urine glucose measurement.

As a result, in the blood glucose measurement mode, in step 213, the microcomputer 100 calculates the blood glucose value from the blood glucose data table stored in the internal memory 102, that is, the blood glucose value corresponding to the measurement data input to the microcomputer 100 is calculated. In the urine glucose measurement mode, the glucose concentration corresponding to the measurement data input to the microcomputer 100 in step 214 is found in the urine glucose data table stored in the memory 102 to calculate the concentration of sugar.

Here, the data table of blood sugar and urine glucose is stored in the ROM (Read Only Memory) of the memory 102 with the values obtained by the test. The blood glucose value or urine glucose value calculated in step 215 is outputted to the display unit 170 for display, and stored in RAM (Random Acces Memory) of the memory 102 in step 216, and the measurement is finished.

As described above, according to the present invention, blood glucose and urine glucose can be selectively measured by one measuring device, so that patients who require periodic measurement can easily measure the concentration of sugar without having to collect blood every time, as well as accurate measurement values. Since it can be obtained, there is an effect that can increase the efficiency of the measuring instrument.
