Method and device for detecting blood

Abstract

The invention discloses a method for detecting blood. The method comprises the following steps: controlling a sampling needle to collect an initial blood sample; controlling the sampling needle to distribute the initial blood sample to a blood routine examination module; controlling the sampling needle to collect a secondary blood sample in the blood routine examination module; controlling the sampling needle to distribute the secondary blood sample to a CRP measuring module; performing blood routine examination on the initial blood sample in the blood routine examination module; performing CRP detection on the secondary blood sample in the CRP measuring module. In a detection process, the secondary blood sample required by the CRP detection is collected by the initial blood sample in the blood routine examination module; the detection item is increased but the blood volume is not increased; the dosage of the collected initial blood sample is the total blood volume; no separating section sample is arranged; the total consumption of the blood sample is reduced and the waste is avoided. The invention also discloses a blood detecting device adopting the method for detecting blood.

Description

technical field [0001] The invention relates to the field of blood analysis, in particular to a blood detection method and a blood detection device. Background technique [0002] In the field of blood analysis, blood routine testing and C-reactive protein (CRP) testing are currently the most commonly used parts. In order to achieve rapid detection of blood routine and CRP parameters to meet clinical testing needs, it is necessary to integrate a blood routine detection module and a CRP detection module into the blood analyzer. [0003] Due to the detection principles and reagents of blood routine and CRP are different, at least two independent channels are required for measurement, and independent sample collection and distribution are required for these channels. The existing method is to draw an appropriate amount of blood at one time, and then realize the distribution of samples to different detection channels through quantitative control. That is, first draw a certain a...

Problems solved by technology

[0004] In this way, because the CRP channel and the blood routine channel independently distribute blood samples, the overall blood consumption is increased, or the sample volume of the corresponding blood routine module is reduced, thus weakening the competitiveness of the product in terms of blood sample consumption, or affecting the blood routine The accuracy level of the module testing items; at the same time, setting the isolation section samples in each distribution section will invisibly increase the overall sample consumption and cause waste
