Abstract
The utility model provides a minisize biochemical analyzer characterized by comprising a light resource, a minisize optical spectrometer, a sample pool and a detector; lights of the light resource passes though the sample pool after passing though the minisize optical spectrometer and then reaches the detector which converts light signals into electrical signals. Clinic rapid-detection of biochemical indexes of samples can be realized by using full spectrum automatic scanning and combining with corresponding reagent boxes. The minisize biochemical analyzer has advantages of small volume, convenient carrying, simple operation and high detection precision.
Description
Technical field
The utility model belongs to field of analytic instrument, particularly a kind of miniature Biochemical Analyzer.
Background technology
At present, the check of biochemical indicator also mainly relies on traditional large-scale Biochemical Analyzer.These automatic or automanual instruments have multiple analytic function, and operating needs higher technical requirement, relatively are fit to check in batches.The rise of MEMS technology and micro-optic technology, make biochemical analysis develop towards " POCT ", the business men of domestic and international many micro spectrometers has all pointed to the application of product the clinical detection of blood sugar, vim and vigour, cancer etc., but only adopt single wavelength to detect mostly, promptly only single project is detected.Can carry out full spectrum autoscan, detect the miniature Biochemical Analyzer of a plurality of projects simultaneously, still rare at home.
Than relatively large Biochemical Analyzer, miniature Biochemical Analyzer reduces greatly at volume, weight, reagent and aspects such as amount of samples, manufacturing cost, patient can oneself be in carry out biochemical investigation, for patients such as the ephrosis that needs long term follow-up, diabetes provide very big facility.The development of miniature Biochemical Analyzer will provide good technical basis and means for the microminaturization of domestic biochemical analyzer.
The utility model content
The purpose of this utility model is to provide a kind of microminiaturization, intellectuality, integrated Biochemical Analyzer.
For achieving the above object, solution of the present utility model is: a kind of miniature Biochemical Analyzer, and it comprises light source, micro spectrometer, sample cell and detector; The light of light source is to arrive detector through passing sample cell behind the micro spectrometer, and detector converts light signal to electric signal.
Described micro spectrometer mainly by entrance slit, and collimating mirror, grating, focus lamp and exit slit form; Light is to pass entrance slit to reflex to grating through collimating mirror and reflex to focus lamp again and penetrate through exit slit.
Described detector adopts 2048 picture dot CCD.
After adopting such scheme, this instrument is gathered by built-in the accurate, quick of micro spectrometer realization signal, in conjunction with the corresponding reagent box, the biochemical indicator of sample is made detection; The light that is sent by light source arrives first catoptron through entrance slit, behind the collimating mirror collimation, incide grating surface, after the light line focus mirror of outgoing behind the grating beam splitting focuses on, by the exit slit outgoing, emergent ray arrives the ccd array detector surface through sample cell, convert light signal to electric signal, by data handling system,, can calculate the related biochemical indicator of sample again in conjunction with the reagent corresponding box.

Embodiment
As shown in Figure 1, miniature Biochemical Analyzer of the present utility model mainly is made up of light source 1, micro spectrometer, sample cell 7, detector 8 etc.Micro spectrometer mainly is made up of entrance slit 2, collimating mirror 3, grating 4, focus lamp 5 and exit slit 6.
The light that is sent by light source 1 arrives collimating mirror 3 through entrance slit 2, behind collimating mirror 3 collimations, incide grating 4 surfaces, after the light line focus mirror 5 of outgoing after grating 4 beam split focused on, by exit slit 6 outgoing, emergent ray was through sample cell 7, arrive ccd array detector 8 surfaces, detector 8 adopts 2048 picture dot CCD, converts light signal to electric signal, passes through data handling system again, in conjunction with the reagent corresponding box, can calculate the related biochemical indicator of sample.
During work, earlier standard model is put into sample cell, the absorbance of testing standard sample, and then the absorbance of test testing sample by comparing twice absorbance data, are handled through related data, can calculate the related biochemical indicator of sample.
The utility model adopts MEMS technology, micro-optic technology and ccd array detector, realizes light signal collection and data transmission accurately and rapidly.
