Full-automatic sample introduction blood cell analysis and measurement method and device

Abstract

The invention discloses a full-automatic sample introduction blood cell analysis and measurement method and device, wherein the method comprises the steps: determining the loading condition of test tubes on a test tube rack in a process that a sample introduction loading platform transversely feeds the test tube rack; under the condition that it is determined that the test tubes are loaded on thetest tube rack, determining test tube types, wherein the test tube types comprise venous blood test tubes and peripheral blood test tubes; determining a uniform mixing mode according to the types of the test tubes, and performing uniform mixing operation on the blood in the test tubes by adopting the determined uniform mixing mode; when the test tube rack is fed to a sample suction position, determining the descending height according to the determined test tube types, and enabling a sampling needle to execute a descending action corresponding to the determined descending height and suck a sample; analyzing and measuring the sucked sample, after analysis and measurement are completed, feeding the test tube rack to an unloading position to be unloaded and withdrawn to an unloading platform,and outputting an analysis and measurement result of the sucked sample. The device is used for realizing the method. The device is 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 fully automatic sample-injection blood cell analysis and measurement, and a method for determining the type of test tube. 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 mixed peripheral blood sampl...

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
