Abstract

The invention is suitable for the field of biological medical electronics, and provides a sample absorption detection method and device and a blood treating device. The sample absorption detection method comprises the following steps of: A, detecting change conditions of a front pipeline light transmittance and a rear pipeline light transmittance of a shear valve in the whole sample absorbing process of a blood analyzer; and B, judging whether the blood analyzer absorbs a sample successfully according to the detected change conditions of the front pipeline light transmittance and the rear pipeline light transmittance of the shear valve in the whole sample absorbing process of the blood analyzer. In the embodiment of the invention, whether the blood analyzer absorbs the sample successfully is judged according to the detected change conditions of the front pipeline light transmittance and the rear pipeline light transmittance of the shear valve in the whole sample absorbing process of the blood analyzer, a blood sample absorption detection method is realized, the condition of discontinuous blood samples in a quantitative pipeline of the shear valve can be avoided being erroneously judged as the success sample absorption, and the accuracy rate of sample absorption detection of the blood analyzer is increased.

Description

technical field [0001] The invention belongs to the field of biomedical electronics, and in particular relates to a blood sample drawing and detection method, device and blood processing equipment. Background technique [0002] The blood analyzer uses a sampling needle to suck the blood sample in the test tube into the blood-separating valve inside the instrument, so that each quantitative pipeline in the blood-separating valve is filled with blood samples, and the blood samples in each quantitative pipeline are used for the detection of various parameters, such as red blood cells. Counting, hemoglobin detection, white blood cell count and classification, etc. [0003] However, due to insufficient blood samples in the test tube and other reasons, the blood sample cannot fill the quantitative pipeline after the sample suction is completed, resulting in inaccurate quantification of the blood separation valve, which in turn affects the accuracy of parameter measurement by the h...
