Abstract

The invention discloses a glycosylated hemoglobin analyzer capable of improving detection accuracy. High-pressure pumps and a mixer are arranged, wherein the high-pressure pumps are connected with outlets of two flowing phases respectively, and the mixer is connected with the outlets of the two high-pressure pumps; the flow velocity of the two high-pressure pumps is controlled to complete the proportion distribution of the two flowing phases in the unit time, and a degassing device and a proportional electromagnetic valve do not need to be arranged, so that the equipment structure is simplified, the problems of inaccurate flowing phase proportion distribution, poor repeatability and the like in the prior art are overcome, and the accuracy of glycation hemoglobin analysis is improved.

Description

technical field [0001] The invention relates to a glycated hemoglobin analyzer, in particular to a glycated hemoglobin analyzer with simple structure and improved detection accuracy. Background technique [0002] Glycated hemoglobin is the cross-linked product of glucose and hemoglobin in the blood. When the concentration of glucose in the blood is high, the content of glycosylated hemoglobin formed by the human body is relatively high. Therefore, glycosylated hemoglobin has been widely used in clinical practice as an effective detection index for diabetes screening, diagnosis, blood sugar control, and efficacy assessment. The principle of the existing glycosylated hemoglobin analyzer is the same as that of the high-performance liquid chromatograph. Its structure is to be provided with a three-way switching valve, which is connected with the first injection pump, the second injection pump, the first two-way switching valve and the sampling Valve (six-way switching valve) is...
