Description
技术领域technical field

在化学或临床方面，对血液样品中所含的分析物进行定量或定性分析是非常重要的。对血液液进行检验在临床诊断中可以及早和可靠地查明病理状态以及有针对性地和基于事实情况地监控身体状态.关在血液的筛检是对在每个人身体内的潜藏疾病提早做一检测，可针对各种成份进行有关在功能指数的检测，当任何检测指示异常时，即表示个人的身体出了某一些毛病，必须提早预防疾病的发病及早期做一治疗。Quantitative or qualitative analysis of analytes contained in blood samples is very important in chemical or clinical aspects. Blood tests can detect pathological conditions early and reliably in clinical diagnosis and monitor physical conditions in a targeted and fact-based manner. The screening of blood is an early detection of potential diseases in each person's body A test can be used to test the functional index of various components. When any test indicates abnormality, it means that there is something wrong with the individual's body. It is necessary to prevent the onset of the disease and treat it early.
在血液分析检测中，关于测量结果的准确性是需要考虑的重要问题。尤其对于确定血液中的葡萄糖含量的检测，由于其是糖尿病患者使用胰岛素剂量的基础，其测量结果需要尽量保证测量结果的准确性。In blood analysis testing, the accuracy of the measurement results is an important issue to be considered. Especially for the detection of determining the glucose content in the blood, since it is the basis for the dosage of insulin used by diabetic patients, the measurement results need to ensure the accuracy of the measurement results as much as possible.
为了实现测量结果的可靠性，200810215254.X的发明专利通过在血液分析系统中设置冗余的评估通道，当通过该分析系统的测量结果偏差大于预定值时，给出该分析系统测量结果错误的信息，从而保证了测量值的准确。但是，由于其中分析系统中增加了冗余，只要分析系统中的一个测量通道出现了错误，即使另外一个测量通道准确，则测量结果也会出现偏差，该分析系统就会给出测量结果错误的信息，这时需要重新进行测试。即该冗余通道的设置增加了系统给出测量结果错误的几率，从而需要重新测试，增加病人的负担。In order to achieve the reliability of the measurement results, the invention patent of 200810215254. X sets redundant evaluation channels in the blood analysis system. When the deviation of the measurement results through the analysis system is greater than the predetermined value, it will give the error of the measurement results of the analysis system. information, thus ensuring the accuracy of the measured value. However, due to the increased redundancy in the analysis system, as long as there is an error in one measurement channel in the analysis system, even if the other measurement channel is accurate, the measurement results will also deviate, and the analysis system will give a wrong measurement result. information, the test needs to be retested. That is, the setting of the redundant channel increases the possibility of the system giving wrong measurement results, thus requiring re-testing and increasing the burden on the patient.

The signal generates a fourth measurement value; (9) The comparator unit 5 compares the deviation S1 between the first measurement value and the fourth measurement value, the deviation S1 between the second measurement value and the fourth measurement value Deviation S2: (9.1) If only S1 is less than a specific first threshold value, it means that the measurement value given by the first evaluation unit 1a is credible, and the analysis result generation unit 8 gives the first measurement value as the blood sample for this time (9.2) If only S2 is less than a specific first threshold value, it means that the measurement result given by the second evaluation unit 1b is credible, and the analysis result generation unit 8 gives the second measurement value as this blood sample (9.3) Otherwise, it means that it is impossible to determine whether the results given by the first evaluation unit 1a and the second evaluation unit 1b are credible, and the analysis result generation unit 8 gives an error message for this measurement result.
