Full-automatic sample injection blood cell analysis and measurement method and device, and method for carrying out blending operation on peripheral blood test tube

Abstract

The invention discloses a full-automatic sample injection blood cell analysis and measurement method and device. The method comprises the following steps: in the process of transversely feeding a sample injection platform to a test tube rack, determining the loading condition of the test tube on the test tube rack; in the case that the test tube is loaded on the test tube rack, determining the test tube type, wherein the test tube type comprises a vein blood test tube and a peripheral blood test tube; determining a blending mode according to the test tube type, and performing blending operation on the blood in the test tube by adopting the determined blending mode; when the test tube rack is fed to a sample suction position, determining the descending height according to the determined test tube type, and executing, by a sampling pin, a descending action corresponding to the determined descending height and sucking the sample; analyzing and measuring the sucked sample, feeding the testtube rack to an unloading position to be unloaded and exit to an unloading platform after measurement and analysis is completed, and outputting an analysis and measurement result of the sucked sample. The device is used for achieving the method. The method and the device in the invention are high in automation degree and high in efficiency, and the labor intensity of clinical personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of blood cell analysis, and more specifically, the invention relates to a method and device for automatic blood cell analysis and measurement of sample injection, and a method for performing a mixing operation on peripheral blood test tubes. Background technique [0002] At present, the automatic sampling blood cell analysis and measurement device is only suitable for venous blood, but for peripheral blood, due to the relatively small blood collection volume, there is currently no corresponding automatic sampling blood cell analysis and measurement device. Because the existing venous blood mixing device in the existing blood cell analyzer is not suitable for peripheral blood mixing, so at the beginning, the operator needs to manually mix, and then hold a well-mixed terminal The test tube of the blood sample is placed under the sampling needle of the hematology analyzer, and the sampling needle draws the mixe...

AI Technical Summary

Problems solved by technology

Because the existing venous blood mixing device in the existing blood cell analyzer is not suitable for peripheral blood mixing, so at the beginning, the operator needs to manually mix, and then hold a well-mixed terminal The test tube of the blood sample is placed under the sampling needle of the hematology analyzer, and the sampling needle draws the mixed peripheral blood sample into the hematology analyzer for detection and analysis. In this case, the hematology analyzer can only analyze the peripheral blood manually. kind of way

However, the efficiency of the manual sampling method is too low, so a device that realizes automatic sampling to a certain extent has appeared on the market. Automatic operation, the operator only needs to put the test tube on the test tube rack instead of holding the test tube under the sampling needle; but the hematology analyzer needs to put the diluent into the test tube first, and then the operator also needs to remove the test tube rack from the hematology analyzer Take it out, add a peripheral blood sample to the test tube filled with diluent, and then put it back into the hematology analyzer. The hematology analyzer will suck and vomit and mix well, and then automatically perform subsequent detection operations

The device has achieved automatic sampling to a certain extent, but manual operation is still required in the middle, that is, after the hematology analyzer injects the diluent into the test tube, the operator needs to take out the test tube, and then manually add a blood sample of peripheral blood into the test tube

And it cannot automatically distinguish between venous blood and peripheral blood, and the efficiency of automatic sampling still needs to be improved
