no. 1 approach

[0018] like figure 1 As shown, the sample analyzer 1 provided by the first embodiment of the present invention is used to analyze the collected samples to be tested. The analysis includes but is not limited to acute phase protein (C-reactive protein, CRP), white blood cell (White Blood Cell, WBC), hemoglobin (Hemoglobin, HGB), red blood cell (Red Blood Cell, RBC), platelet (Platelets, PLT) and other items of testing.

[0019] The sample analyzer 1 includes a sample aspirating device 10 , a reagent tank 11 , a reaction pool 12 , a detector 13 , a cleaning solution storage tank 14 , a liquid transport device 15 , a human-computer interaction device 16 , a memory 17 and a processor 18 . The sample aspirating device 10 , the reagent tank 11 , the reaction tank 12 , and the cleaning solution storage tank 14 are connected directly or indirectly through a liquid transmission device 15 for liquid transmission. The sample aspirating device 10 , the detector 13 , the human-computer in...

no. 2 approach

[0038] like figure 2 As shown, the structure of the sample analyzer 2 provided by the second embodiment of the present invention is basically the same as that of the sample analyzer 1 provided by the first embodiment of the present invention, the difference is that the liquid transport device 25 includes a driver 250 And take liquid pipe 252. The driver 250 is connected with the liquid-taking tube 252 for moving the liquid-taking tube 252 to a preset position. The liquid extraction tube 252 is used for drawing or releasing liquid. The execution module 196 of the cleaning controller 19 is connected to the driver 250, and is used to control the driver 250 to drive the liquid pipe 252 to draw the cleaning solution from the cleaning solution storage tank 14 to analyze the sample when the comparison module 194 judges that the residual amount of the reactant exceeds the standard. Instrument 2 is cleaned.

Abstract

The present invention relates to a sample analyzer, which comprises a sample suction device, a reaction cell, a detector, a cleaning liquid storage tank, a liquid transmission device and a cleaning controller, wherein the sample suction device sucks and conveys a sample to be tested to the reaction cell so as to be subjected to a measurement reaction, the detector detects the detection items of the reactant generated by the measurement reaction, a cleaning solution is stored in the cleaning liquid storage tank, and the cleaning controller is separately connected to the sample suction device and the detector so as to obtain detection parameters, determines whether the residual reactant exceeds a standard according the detection parameters, and controls the liquid transmission device to suckthe cleaning solution from the cleaning liquid storage tank so as to perform cleaning operation when the residual reactant exceeds the standard. The invention further relates to a cleaning control method of the sample analyzer.

Description

technical field [0001] The invention relates to a sample analyzer and a cleaning control method for cleaning the sample analyzer. Background technique [0002] Existing sample analyzers generally need to react the sample to be tested with the reaction reagent in the reaction cell when the immunolatex method is used for measurement, and part of the reactant will remain in the reaction cell after the test is completed. Accumulation of the residual reactants to a certain amount in the reaction cell will affect the accuracy of subsequent measurement values, so the residual reactants need to be cleaned. Common cleaning methods include cleaning after each test and regular cleaning at intervals. However, cleaning after each test and regular cleaning can reduce the cleaning time while ensuring the cleaning effect, which is difficult to meet the current test speed requirements. Contents of the invention [0003] In view of this, it is necessary to provide an optimized sample anal...
