Automatic liquid dispensing system and method suitable for chemiluminescence immunoassay analyzer

Abstract

The invention discloses an automatic liquid dispensing system and a method suitable for a chemiluminescence immunoassay analyzer, wherein the system comprises a control panel, a diaphragm pump, a mixing tube, a peristaltic pump, a solenoid valve, and a heating membrane. The control panel monitors the liquid level of a purified water container, a concentrated liquid container, and a cleaning liquidcontainer, controls the open and close of the diaphragm pump, the peristaltic pump, and the solenoid valve, monitors the temperature of the concentrated liquid container, and controls the operation of the heating membrane. The purified water and the concentrated liquid are respectively mixed in the mixing tube under the control of the diaphragm pump and the peristaltic pump, and then enter the cleaning liquid container. The heating membrane controls the concentrated liquid container to maintain a constant temperature. The control panel uses a heating membrane to perform a constant temperaturecontrol for the concentrated liquid container to prevent crystallization during the use of the concentrated liquid, thereby avoiding the problem of inaccurate concentration of the cleaning liquid after mixing; the automatic configuration saves the labor cost and avoids high labor intensity; the liquid concentration is more accurate and the process is simple; and as long as the relevant parametersare set in advance, it is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic liquid dispensing system and method suitable for a chemiluminescence immunoassay analyzer. Background technique [0002] The chemiluminescence immunoassay analyzer is a medical testing instrument that performs immune analysis on the human body by detecting the patient's serum. It quantitatively analyzes the concentration of the molecules to be tested in the sample according to the mathematical model established by the standard, and finally prints the data report to assist clinical diagnosis. . The cleaning solution in the chemiluminescence immunoassay analyzer is mostly used for cleaning the cuvette, sampling needle, and reagent needle, and the frequency of use is relatively high. [0003] At present, the cleaning solution is mostly prepared by manually adding the concentrated solution, then adding quantitative purified water according to a fixed ratio, mixi...
