Calibrating method of electrolyte analyzer

Abstract

The invention discloses a calibrating method of an electrolyte analyzer. The calibrating method comprises the following steps of: sucking in an slope correcting liquid so as to clean a pipeline and completely discharging the slope correcting liquid; sucking in the slope correcting liquid so as to cover an electrode, and measuring an electrode millivolt value; sucking in an electrode drifting liquid so as to clean the pipeline and completely discharging the electrode drifting liquid; sucking in an electrode drifting liquid so as to cover the electrode, and measuring the electrode millivolt value of the electrode drifting liquid; calculating the average value of the measured electrode millivolt values and values (recorded before) of the slope correcting liquid and the electrode drifting liquid and then calculating a slopevalue; calculating the concentration of the electrode drifting liquid according to the calculated slope value and the measured millivolt of the electrode drifting liquid, comparing the concentration with a standard concentration; and if the difference is less than a set value, determining that the calibration is passed. By utilizing the calibrating method of the electrolyte analyzer, the slope value can be calculated by calibrating the values of the slope correcting liquid and the electrode drifting liquid once and combining the electrode millivolt value measured during the calibration, the real-time capability and precision in calibration are ensured, the slope correcting liquid and the electrode drifting liquid are calibrated once, so that the slope correcting liquid and the electrode drifting liquid are saved; and moreover the pipeline is cleaned before the calibration so that the cross contamination is avoided.

Description

technical field [0001] The invention relates to a calibration method for medical equipment, in particular to a calibration method for an electrolyte analyzer. Background technique [0002] The calibration methods of electrolyte analyzers currently used generally include: one-point calibration and two-point calibration. For one-point calibration, it is necessary to save the calibration value of the slope calibration solution first, then calibrate the electrode drift solution, and use the measured value of the electrode drift solution and the saved value of the slope correction solution to calculate the slope; two-point calibration is performed every time. Calibrate the electrode drift fluid and slope calibration fluid, measure their values, and then calculate the slope. Two-point calibration The calibration process is quite diverse. The common practice is to calibrate the electrode drift solution 3 times, then calibrate the slope correction solution once, and use the electro...

Problems solved by technology

[0003] However, one-point calibration only calibrates the electrode drift liquid each time, and the slope correction liquid is the measured value saved before, so the accuracy and real-time performance cannot be guaranteed.

[0004] During the two-point calibration process, it is necessary to measure the electrode drift solution three times and the slope correction solution once, resulting in a serious inconsistency in the usage of the electrode drift solution and the slope correction solution; in the two-point calibration process, it is necessary to calibrate the electrode drift solution three times for each calibration. The amount of electrode drift liquid used is large; in the two-point calibration process, after the electrode drift liquid is calibrated, the slope correction liquid is calibrated, and the slope correction liquid is only calibrated once, which is easy to cause cross-contamination
