Urine analytical method and urine analyzer realizing analytical method

Abstract

The invention relates to a urine analytical method and a urine analyzer realizing the analytical method. The method comprises the steps of: collecting a reflective light signal of a white point reflective test light source to control and adjust the light intensity of a test light source till the reflective light signal intensity of the a white point reaches a predetermined value; starting the test, setting a reaction waiting time, wherein a test reagent in a test strip reacts with corresponding components in the urine independently; then collecting data to of a test tape formed by corresponding test reagent according to test items; and comparing the data of the test strip with standard data or standard curves and analyzing data of the test items. The stability of the brightness of the test light source is ensured through the urine analytical method and a the urine analyzer realizing the analytical method, wherein the method comprises the step of collecting the reflective light signal of the white point reflective test light source to control and adjust the light intensity of the test light source till the collected reflective light signal intensity of the white point reaches the predetermined value. The precision and stability of the test result are ensured by controlling the brightness of the test light source in real time, so that the attenuation problem of the test light source is improved.

Description

technical field [0001] The invention relates to a medical analysis method, in particular to a urine analysis method and a urine analyzer for realizing the analysis method. Background technique [0002] The current urine analyzer uses a light-emitting diode as a test light source, and uses a receiving tube to receive dual-wavelength reflected light to measure the color change on the test strip for semi-quantitative measurement. [0003] The light-emitting diode is used as the test light source. Due to the attenuation of the diode itself, the accuracy and stability of the result cannot be guaranteed. It is necessary to adjust the brightness of the light source from time to time, which brings inconvenience to the test and the hidden danger of abnormal results. The failure rate is high. , The problem of high maintenance costs. And it is necessary to manually correct the light-emitting diodes from time to time. [0004] The sample preparation of the urine analyzer is basically ...

AI Technical Summary

Problems solved by technology

[0003] The light-emitting diode is used as the test light source. Due to the attenuation of the diode itself, the accuracy and stability of the result cannot be guaranteed. It is necessary to adjust the brightness of the light source from time to time, which brings inconvenience to the test and the hidden danger of abnormal results. The failure rate is high. , high maintenance costs

And it is necessary to manually correct the light-emitting diodes from time to time

[0004] The sample preparation of the urine analyzer is basically a manual operation. Due to the different habits and techniques of each operator, the intuitive understanding of the reaction time between urine and the test strip is also different, resulting in incomplete or excessive reaction of the test strip. phenomenon, this problem will bring the hidden danger of abnormal results

The waiting time for the reaction of urine and test strips is generally fixed and cannot be used flexibly. Due to the different habits of different doctors, the results of some items may be biased

[0005] In actual clinical practice, the color of urine varies greatly, and the darker color will stain the test paper with the color of urine, which interferes with the color change of the reaction and affects the accuracy of the test.
