Abstract
An iodine automatic detecting apparatus comprises a shell, an electromechanical driving and liquid feeding system, a photoelectric system, a microprocessor control system, and a serial of chemical reagent, and the electromechanical driving and liquid feeding system, the photoelectric system, the microprocessor control system, and the serial of chemical reagent are arranged in the shell. According to the programs of the microprocessor, a discrete flow injector takes a serial of operations that a step motor drives a peristaltic pump to rotate, and an electromagnet sucks simultaneously. Due to the peristalsis of a groove pressing board and the peristaltic pump, a liquid feeding pipeline draws the reagent and sequentially injects the reagent into test tubes with the help of the rotation of a disk frame driving device. The time value of the discoloration reaction and the light wave in a color comparison tube are transformed into electrical signals via photoelectric conversion, then the iodine content of a sample is worked out by the microprocessor, and the result is displayed and printed out. The optic-mechanic-electronic apparatus can automatically complete the operations from sample feeding to result printing, and 30 samples can be detected simultaneously.
Description
The utility model relates to a kind of instrument that detects I, and it is to be specifically designed to the automatic analytical instrument of measuring I content in biosome (as people's urine, blood), water body, soil and the salt.
IDD (Iodine deficiency disorders) (IDD) is the biogeochemical disease that the physical environment iodine deficiency because of human survival causes, is the one of the main reasons that causes human mind's obstacle, and it has become global ubiquitous public health problem.China is one of serious popular country of IDD (Iodine deficiency disorders), and the method for measuring I is the important means of preventing and treating IDD (Iodine deficiency disorders), and the content that accurately detects I is to prevent and treat the IDD (Iodine deficiency disorders) important evidence.Scholars think that people's urine iodide level is the suitableeest index of estimating and monitor nutrition status of iodine.
" place of china sick control magazine " the 3rd periodical in 2000 has carried the survey article of a piece " urine iodine assay method is learned progress ", the description that its is summarized both at home and abroad to the improvement of urine iodine detecting method.The urine iodine mensuration that present international three joint groups are knitted (WHO, UNICEF, ICCIDD) recommendation is the A method, China expert makes according to the national conditions of China and is suitable for the exercisable chemical analysis of common laboratory on this basis---and " the arsenic cerium catalysis spectrophotometric determination method of urine iodine ", this method was carried out as health industry standard (WS/T 107-1999) in 1999.Standard method is a kind of manual chemical analysis, because technical conditions, the operation steps of whole testing process are strict, is not high-quality analyst, and bad to precision, the accuracy control of method, resultant error is bigger.As the disease of substantial connection being arranged, should on analysis means, realize the instrumentation operation, to adapt to the needs of preventing and controlling with the human mind.
The purpose of this utility model provides a kind of analytical instrument of full-automation detection I of light harvesting electromechanical, need not manual operations to printing testing result from sample introduction.Particularly the design of discrete flow injection device and test tube support plate rail drive unit is better than the prior art of the up-to-date single hose flow injection device of the nineties.
In order to achieve the above object, the technical solution of the utility model is: the full-automatic detector of a kind of I, it adds liquid systems, electro-optical system, microprocessor (single-chip microcomputer) control system, the serial automatic analytical instrument of forming one of chemical reagent by the casing and the Mechanical ﹠ Electrical Transmission in the casing of instrument.It is to be made of discrete flow injection device and tray rack drive unit that described Mechanical ﹠ Electrical Transmission adds liquid systems; Described electro-optical system is to be made of optical module and photoelectric switching circuit; Described microprocessor (single-chip microcomputer) control system comprises programmed instruction (software) and electronic devices and components and circuit board (hardware) composition, finishes various functions automatically by programmed control; Described chemical reagent series be chemical method survey iodine the group reagent solution that must use, be stored in respectively in the reagent bottle separately, add liquid systems through mechanical drive and pump to sample tube from reagent bottle and inject; Described casing is provided with printer, display and button on panel.
With human body urine iodine is example, and the analyst opens the instrument protecgulum, puts into the colorimetric test tube pallet that sample is housed, sample does not need digestion process, behind the startup instrument, and whole testing process, all finish automatically to printing the result from sample introduction, can while analyzing and testing 30 duplicate samples in 30 minutes.Equally also can detect the I in the materials such as water body, soil and salt.The utility model is with full-automatic detection I, and wide ranges, the time of its detection level is fast, sample is many, has replaced manual chemical method, has reduced the error that causes because of manual operations, has improved the precision and the accuracy of test sample.
