Full-automatic intelligent urine iodine analyzer and operating method thereof

Abstract

The invention relates to a full-automatic intelligent urine iodine analyzer, which comprises a shell, a sample carrier mechanism, a reagent liquid adding device, a light path detection system, a comprehensive sample processing mechanism, a waste trough and an electric control system. By adoption of a quantitative colorimetric method, point-to-point operation of various reagents is realized throughcontrol of reagent disc rotation; by adoption of a sample adding stirring device, mixing of to-be-tested reagents is realized, cross contamination of samples is avoided, and mixing efficiency is improved; by a double-reagent-needle sample adding arm, a color developing agent and an oxidant adding function is realized, detection time is shortened, and internal and external spaces of equipment aresaved; functions of automatic result interpretation and automatic report printing are achieved, urine iodine detection automation is improved, errors caused by manual sample adding are effectively avoided, urinalysis detection precision and detection efficiency are improved, and detection cost is reduced.

Description

technical field [0001] The invention belongs to the field of analytical instruments, in particular to a fully automatic intelligent urine iodine analyzer. Background technique [0002] Iodine is one of the trace elements with important biological effects. It is closely related to the growth and metabolism of the human body. Therefore, it is particularly important to accurately evaluate the degree of iodine deficiency in the population and timely monitor the iodine nutritional status of the population after iodine supplementation. Urinary iodine excretion is closely related to iodine intake, and is an important index to evaluate the human iodine nutrition level and the efficacy of iodine supplementation. Whether the human body is deficient in iodine can be diagnosed by detecting urinary iodine, thereby diagnosing whether the human body suffers from a certain disease or predicting a disease. [0003] However, the iodine content in human urine is very small, only a few tenths ...

AI Technical Summary

Problems solved by technology

The above-mentioned technology already has the function of automatic urine iodine measurement, but there are still disadvantages in the above-mentioned technology: According to the patent 201620092824.0, it can be known that the chemical agent adding rod in this scheme can only add the prepared additives to the processing bottle, and if the urine iodine is used In the spectrophotometric method in iodine analysis, it is necessary to add the chromogenic agent and oxidizing agent step by step to the test reagent, and the chromogenic agent and oxidizing agent are stored separately and added separately, and no related plan is given in this technical plan

Moreover, in the above technology, for the reagents mixed with chemical additives and samples in the treatment bottle, no mixing technical means and scheme are given, which is unreasonable in practical applications; this scheme mentions the use of a negative pressure module to Negative pressure is drawn from the liquid in the treatment bottle, but according to the actual situation, the treatment bottle is an open device, and the liquid inside it always maintains an atmospheric pressure state. According to the principle of air pressure balance, the implementation of this scheme is obviously unreasonable; and the scheme mentions the use of sampling needles to achieve The liquid in the treatment bottle is mixed, but after the liquid in the first treatment bottle is mixed, the sampling needle has formed a pollution source, and the second mixing cannot be used, so the equipment can only complete the mixing function once

Finally, it is mentioned in the scheme that the nozzles for adding samples are disposable nozzles, and there is also a waste nozzle plate in the middle of the test plate, but if continuous automatic measurement is to be realized, the used nozzles need to be disposed of Pull it out and put it in the waste gun nozzle tray. Obviously, the present invention does not give the relevant implementing mechanism and corresponding method

[0011] To sum up, the existing urine iodine analyzers have relatively simple functions, and even equipment with high automation has relatively large disadvantages, and the degree of automation and efficiency are extremely limited. How to design an efficient, simple, and fully automatic urine iodine analyzer is imminent
