Abstract: The present invention relates to a system for measuring the hemoglobin concentration in whole blood, wherein the system comprises: a light-radiating unit including a light source that emits two types of incident light having different wavelengths; a diffusion unit which diffuses the incident light emitted by the light-radiating unit; a cuvette-holding unit which is formed so as to hold a cuvette including a blood sample; a detection unit which detects each absorbance of the two types of incident light having different wavelengths; a processing unit which determines the hemoglobin concentration in the blood by processing the measured absorbance result; and a control unit which regulates the two types of incident light having different wavelengths in order to repeatedly/sequentially radiate same. Although the system for measuring hemoglobin in whole blood of the present invention uses a small amount of whole blood, it is possible to measure the total hemoglobin concentration in an accurate and reliable manner. The system of the present invention aligns the paths of two types of incident light having different wavelengths passing through a microcuvette by using a diffuser plate so as to easily align a light source and increase the reliability of the results. Also, the system of the present invention uses two wavelengths so as to rapidly and accurately measure the total amount of hemoglobin, including oxidized and reduced hemoglobin.

Abstract translation: 本发明涉及一种用于测量全血血红蛋白浓度的系统，其中该系统包括：一个包含发射两种波长不同的入射光的光源的光辐射单元; 漫射单元，其漫射由所述光辐射单元发射的入射光; 形成为保持包括血液样本的比色皿的比色皿保持单元; 检测单元，其检测具有不同波长的两种类型的入射光的每个吸光度; 处理单元，其通过处理所测量的吸光度结果来确定血液中的血红蛋白浓度; 以及控制单元，其调节具有不同波长的两种类型的入射光以便重复/顺序地辐射它们。 虽然本发明的全血中的血红蛋白测定系统使用少量全血，但是可以准确可靠地测定总血红蛋白浓度。 本发明的系统通过使用扩散板对准通过微型玻璃的不同波长的两种类型的入射光的路径，以便容易地对准光源并增加结果的可靠性。 此外，本发明的系统使用两个波长，以便快速且准确地测量血红蛋白的总量，包括氧化和还原的血红蛋白。
