Description

Technical Field

[0001] The invention relates to a blood sugar detection device and a blood sugar detection method, belonging to the technical field of blood sugar detection devices. Background Art

[0002] Blood sugar is a very important indicator in the diagnosis, treatment and management of diabetes. Blood sugar test results not only help to assess the degree of glucose metabolism disorder in diabetic patients and formulate reasonable glucose-lowering plans, but also objectively reflect the effect of glucose-lowering treatment and guide the adjustment of lifestyle and treatment plans.

[0003] At present, the main methods for blood glucose detection are laboratory biochemical analyzer determination and portable blood glucose meter determination. Among them, biochemical analyzer is accurate and reliable for measuring venous blood glucose, and is a recognized method for diagnosing diabetes. However, the laboratory biochemical method requires a large amount of blood and the determination process is time-consuming, which is not suitable for rapid blood glucose monitoring in diabetic patients. Portable blood glucose meter detection is simple, fast and accurate, and is increasingly recognized and accepted by diabetic patients. It is an effective tool for diabetic patients to conduct self-blood glucose monitoring. However, due to the limitations of portable blood glucose meter detection methods, it can only be used for blood glucose level monitoring but not for diabetes diagnosis. For more than half a century, the advent of portable blood glucose meters has brought more precise goals to diabetes treatment and management. Including other intensive treatment groups, more stringent blood glucose monitoring has been adopted. For the blood glucose management of relatively complex hospitalized patients, especially critically ill patients, if an inaccurate blood glucose monitoring system is used, the risk of clinical adverse events, severe hypoglycemia events, and even death will increase. In my country, most hospitals use SMBG-based blood glucose meters. With the advancement of in-hospital blood sugar management and the popularization of information-based blood sugar monitoring, the use of more accurate POCT blood sugar testing systems will receive more and more attention. With the development of technology, blood sugar monitoring systems are constantly iterating. Instant, convenient, efficient and accurate are the future development direction of blood sugar testing technology.

[0004] The main function of the blood glucose detector of the present invention is to detect the glucose content in human blood, which is used for monitoring / detection and diagnosis of diabetes, and truly solves the core requirements of blood glucose monitoring / detection: convenient, instant, accurate, and data networking. The blood glucose detector has a wide range of applications and can be used for accurate blood glucose detection in primary / general hospital wards, ICU blood glucose detection, emergency blood glucose detection, perioperative blood glucose detection, pregnancy blood glucose detection, community health management blood glucose detection, etc., covering all professional medical institutions that need to perform blood glucose detection.

[0005] To this end, a blood sugar detection device and a blood sugar detection method are proposed. Summary of the invention

[0006] In view of this, the present invention provides a blood glucose detection device and a blood glucose detection method to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the present invention is implemented as follows: a blood glucose detection device and a blood glucose detection method, including a blood glucose detector body, wherein the interior of the blood glucose detector body includes a power cord, a desktop AC adapter, a PCBA, a motor guide rail, a motor, an embedded display, a pump base, a pump pressure slider, a pump block, a pump roller seat, a pump roller, a reaction pool, a heat conductive block, a switch support seat, a support base plate, a sensor switch, a sampling needle, a lifting plate, a sampling needle pressure plate, a flushing valve bracket, a lifting base, a mechanical arm sensor bracket, a single channel base, a sensor bracket, an ECO flushing valve, a valve plug, a torsion stopper, a fixed bearing plate, a sliding tube, a needle seat, a shaft nut, a synchronous T-gear, a bearing bolt, a slider support seat, a nameplate seat, a nameplate, a mechanical arm reference sensor, a ball bearing, an O-ring, a sliding film, a sealing ring, a synchronous belt, a neodymium magnet, a motor shock-absorbing pad, a drill sleeve with a boss, a connector, a USB adapter, a connector, a power resistor, a temperature sensor, a metal probe, a probe sliding sleeve, a button switch, a bubble sensor, a micro switch, a fan, a photoelectric sensor, and a capacitive sensor.

[0008] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0009] 1. The present invention can be used for the diagnosis and monitoring of diabetes by providing a blood glucose detector body. The relative deviation of the measurement result and the nominal value of the sample is within the range of ±3%, and the coefficient of variation CV of the repeatability measurement is not greater than 1.5%. Within the detection range, the linear correlation coefficient r of the test result is not less than 0.99, and the carryover contamination rate is not greater than 3.0%; within 8 hours of startup stability, the relative deviation of the test result of the same normal sample does not exceed ±5.0%, and the detection time of a single sample is less than 20s. The blood glucose meter body is different from other POCT blood glucose meters and biochemical analyzers; it is applicable to Chapter 3 Laboratory Diagnosis (Clinical Chemistry Test): Glucose Determination Project of the "National Technical Specifications for Medical Service Projects (2023 Edition)".

[0010] Second, the present invention sets the blood glucose detector body, and the built-in QC software management system, test data AI spectrum comparison system and critical value alarm function developed by the blood glucose detector body meet the requirements of relevant regulations and standards for point-of-care testing (POCT). Built-in QC software management system: The present invention sets the blood glucose detector body to detect the glucose content of human blood, and it integrates the quality control function to meet the laboratory's demand for quality control. The instrument sets the control position, and the user can use a third-party quality control liquid, and can change the target value range, manufacturer and batch number information of the quality control liquid according to different quality control liquids. At the same time, the instrument will count the internal quality control results, and automatically calculate the average value, standard deviation, CV value, variance, etc., which is convenient for users to trace, manage and evaluate the quality control results. The test data AI spectrum comparison system: Any questionable results can be traced back and the calibration curve can be used to determine whether the state of the blood glucose meter at the time of detection is normal. After automatic comparison by the system, regardless of any abnormality in the detection crisis value setting and automatic alarm function data caused by any reason, the instrument will automatically test the sample for the second time. If the data is abnormal again, the instrument will display the test result as "--" and will automatically test the next sample, critical value setting and automatic alarm function: the present invention can set the critical value according to the internal requirements of the medical institution by setting the blood glucose detector body (the critical value is set at 2.2mmol / L~22.2mmol / ), and the test results that exceed the threshold range (higher or lower than) will be displayed in red to remind medical staff to pay attention to handling the critical value.

[0011] 3. The present invention sets a blood glucose detector body, and the blood glucose detector body adopts the world-recognized standard "enzyme electrode" technology for blood glucose detection. High sensitivity: through the optimized layer material and enzyme immobilization process, the sensor has high sensitivity and can detect low concentrations of glucose. High stability: the aqueous acrylic modified polyester cross-linked with amino resin provides a stable coating to ensure the long-term activity of the enzyme and the stability of the sensor. High selectivity: the optimized coating material and enzyme immobilization process improve the selectivity of the sensor and reduce the influence of interfering substances. Fast response: the combination of high conductivity and high activity enzyme improves the response speed of the sensor and shortens the detection time. Environmental protection: the aqueous acrylic modified polyester is a low VOC (volatile organic compound) environmentally friendly resin that meets environmental protection requirements and reduces detection costs: the blood glucose detector body and its supporting reagents have obtained relevant invention patents. Compared with blood glucose test strips, its production process is more concise and efficient, and the production cost is lower. It can reduce the procurement cost and maintenance cost of primary medical institutions and medical institutions at all levels, and avoid waste of resources and repeated investment;

[0012] Fourth, the present invention supports the connection to the hospital information system (HIS) and the laboratory information system (LIS) by setting up the blood glucose tester body, so as to realize the seamless connection of data. This not only simplifies the data management process, but also improves the accuracy and timeliness of the data. Network and serial port connection: the device supports a variety of connection methods, including network connection and serial port connection, to ensure flexible use in different environments. Built-in database: the device itself is equipped with a database, which can save the test curves and values, and help doctors to perform double checks and tracebacks. The preservation and management of historical data provides strong support for medical decision-making. Data communication security: the device adopts advanced encryption technology to ensure the security and privacy protection of data transmission, and meets the data security standards of the medical industry. Equipped with relevant hospital-wide blood glucose management software, the patient's blood glucose data can realize the whole process control, which truly solves the needs of in-hospital diabetes diagnosis and treatment.

[0013] 5. The present invention sets up a blood glucose tester body, which can be used as a unified and optimized grassroots blood glucose testing tool. The blood glucose tester body has more standardized operating procedures and technical standards, which ensures the standardization and normalization of the monitoring process, reduces operating errors, improves the reliability of monitoring results, reduces usage costs, simplifies operations, improves testing efficiency, and improves patient compliance. By setting up the blood glucose tester body to promote data sharing, the problem of inconsistent data formats can be solved, cross-regional and cross-institutional data sharing and exchange can be achieved, and the cooperation between grassroots medical institutions and medical institutions at all levels can be strengthened, and the "awareness rate", "treatment rate" and "blood glucose control compliance rate" of diabetes can be improved.
