Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The existing blood sugar detection equipment cannot comprehensively reflect blood components, so that the result of blood sugar concentration still has deviation. According to the invention, the alternating current test of the blood glucose test paper to be tested is realized by using the alternating current generation module and the alternating current detection module, and the final blood glucose concentration is determined by using two different test environments of alternating current and direct current, so that the test result is more comprehensive, the blood glucose test precision is improved, and each result is more accurate.
The embodiment of the invention discloses a blood sugar detection system, which is shown in figure 1 and comprises:
the alternating current generating module 1 is used for generating alternating current voltage with preset amplitude and preset frequency;
the alternating current detection module 2 is used for applying alternating current voltage to the blood glucose test paper to be detected to obtain an alternating current feedback signal;
the direct current detection module 3 is used for applying direct current voltage to the blood glucose test paper to be detected to obtain a direct current feedback signal;
and the data processing module 4 is used for determining the blood glucose concentration corresponding to the blood glucose test paper to be tested according to the alternating current feedback signal and the direct current feedback signal.
The preset frequency of the alternating voltage generated in the alternating current generation module 1 is usually 3.2kHz, the preset frequency is set according to the resistance-capacitance characteristics of blood, the amplitude of the preset frequency can be set and adjusted according to the actual setting, usually about 30mV, and the amplitude is output to the alternating current detection module 2 after passing through a second-order active filter.
It can be understood that the coupling coefficients of the blood glucose test paper to be tested to the alternating voltage before and after adding the blood sample are different, the alternating current detection module 2 receives an alternating current feedback signal of the alternating current response of the blood glucose test paper to be tested, and the alternating current feedback signal is amplified and subjected to wave crest detection to obtain an alternating current test result.
Similarly, the feedback current of the blood glucose test paper to be tested to the direct current voltage is different before and after the blood sample is added, the direct current detection module 3 detects the direct current feedback signal of the direct current response of the blood glucose test paper to be tested, and the direct current feedback signal is subjected to current-voltage conversion and amplification to obtain a direct current test result.
It can be understood that, in order to ensure accurate measurement and perform multiple detections, the data processing module 4 averages a plurality of ac feedback signals to obtain a final ac feedback signal, and averages a plurality of dc feedback signals to obtain a final ac feedback signal. Of course, in addition to averaging, other processing may be performed on the original feedback signal to obtain a more effective feedback signal as the final feedback signal.
That is to say, the ac feedback signal and the dc feedback signal corresponding to the blood glucose test strip to be tested both include two parts of signals, one part is the feedback signal of the blood sample, the other part is the feedback signal of the blood glucose test strip, and the feedback signal of the blood glucose test strip is actually the interference signal that needs to be eliminated during blood glucose detection, so the data processing module 4 is specifically configured to:
when no blood sample is added to the blood glucose test paper to be detected, acquiring an alternating current background signal of an alternating current detection module and a direct current background signal of a direct current detection module;
preprocessing the AC feedback signal and the DC feedback signal according to the AC background signal and the DC background signal respectively;
and determining the blood glucose concentration according to the preprocessed alternating current feedback signal and the preprocessed direct current feedback signal.
Here, the ac background signal and the dc background signal are feedback signals of the blood glucose test strip, and the preprocessing is usually: the ac background signal is subtracted from the ac feedback signal and the dc background signal is subtracted from the dc feedback signal.
Further, the data processing module 4 calculates the blood glucose concentration of the blood sample on the blood glucose test paper to be tested according to the amplitude of the dc feedback signal, the peak value of the ac feedback signal, and other information, i.e., the above-mentioned dc test result and ac test result.
Further, the blood sugar detection system further comprises:
the temperature detection module 5 is used for detecting the current environment temperature;
the data processing module 4 is also used for performing temperature compensation on the blood glucose concentration according to the ambient temperature.
It is understood that the activity of each component in the blood sample is slightly different under different environmental temperatures, so the theoretically calculated blood glucose concentration is not accurate and needs to be calibrated through temperature compensation.
Further, the blood sugar detection system further comprises:
and the resistance detection module 6 is used for detecting the resistance value of the blood glucose test strip to be detected so as to determine whether the batch or the resistance code of the blood glucose test strip to be detected is suitable for the blood glucose detection system.
Generally, four or eight sets of resistors are built in the blood glucose test strip, and the factory information of the blood glucose test strip, such as batch and resistor code, can be known through the resistance value, and whether the blood glucose test strip can be used in the blood glucose detection system is determined.
Further, the blood sugar detection system further comprises:
the analog-to-digital conversion module 7 is used for performing analog-to-digital conversion on the alternating current feedback signal and the direct current feedback signal;
and the precision selection module 8 is used for setting the precision of the analog-to-digital conversion module 7.
It can be understood that the precision here includes 12 bits, 13 bits, 15 bits, 16 bits, etc., the Analog-to-Digital conversion module 7 is configured to have a corresponding precision through the precision selection module 8, the Analog-to-Digital conversion module 7 generally adopts a sigma-delta structure, and is specifically configured to perform Analog-to-Digital conversion on the ac feedback signal and the dc feedback signal through an oversampling ADC (Analog-to-Digital Converter), so as to eliminate environmental disturbance and system disturbance during the test process and improve the blood glucose test precision.
It will be appreciated that in addition to these modules, the blood glucose detection system may include: the blood glucose test device comprises a blood glucose test strip insertion port, a data output port, a power module for supplying power to each module, a switch module for controlling the power module, a low-voltage detection module for detecting the electric quantity of the power module and giving out a prompt when the electric quantity is low, a high-precision benchmark module for generating a reference value for signal measurement, and the high-precision benchmark module can utilize the temperature characteristics of an internal semiconductor PN junction and a resistor and fuse trimming to generate a zero temperature drift benchmark voltage of 2.048V.
Generally, the blood glucose concentration test of the blood glucose test system in this embodiment takes the state of the blood glucose test strip as a stage point: before the blood glucose test paper is not added with a blood sample, a blood glucose detection system is initialized and carries out self-checking on test environment parameters, and the action does not require the insertion of the blood glucose test paper; after the blood glucose test paper without the blood sample is inserted into the blood glucose test paper insertion hole, judging whether the blood glucose test paper is applicable or not by using the resistance detection module 6, if so, respectively obtaining an alternating current background signal and a direct current background signal, and then reminding the blood glucose test paper to add the blood sample, namely obtaining the blood glucose test paper to be detected; and detecting the blood glucose test paper to be detected, wherein the whole detection process is described above, and the blood glucose concentration is obtained and output through a data output port.

In the embodiment of the invention, the alternating current test of the blood glucose test paper to be tested is realized by using the alternating current generation module and the alternating current detection module, and the final blood glucose concentration is determined by using two different test environments of alternating current and direct current, so that the test result is more comprehensive, the blood glucose test precision is improved, and each result is more accurate.
