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

Abstract

The invention discloses a full-automatic sample introduction type blood cell analysis and measurement method and device. The method comprises the steps of: determining a loading condition of a test tube on a test tube rack during the process of laterally feeding the test tube rack by a sample introduction loading platform; when it is determined that the test tube is loaded on the test tube rack,determining a test tube type, wherein the test tube type comprises a venous blood test tube and a peripheral blood test tube; determining a uniform mixing mode according to the test tube type, and performing a uniform mixing operation on the blood in the test tube by using the determined uniform mixing mode; when the test tube rack is fed to a sample suction position, determining a descending height according to the determined test tube type, and executing, by a sampling needle, a descending action corresponding to the determined descending height, and sucking a sample; performing analysis andmeasurement on the sucked sample, after the analysis and measurement are completed, feeding the test tube rack to an unloading position to be unloaded and exit onto an unloading platform, and outputting an analysis and measurement result of the sucked sample. The device is used for implementing the method. The full-automatic sample introduction type blood cell analysis and measurement method anddevice disclosed by the invention have the advantages of high automation degree, high efficiency, and capability of reducing the labor intensity of the clinical staff.

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 sample-injecting blood cell analysis and measurement. 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 sample into the hematology analyzer for detection and analysis....

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 an
