Raw diagnosis provides effective reference data.Therefore, specific protein analyser is a kind of widely used in medical institutions biochemical point
Analyzer.
To analyze from in-vitro diagnosis (IVD) instrument industry：One is the full-automatic development to whole detection, and two is to quick
The direction of small-sized instant analysis instrument (POCT) is developed.Due to domestic populous, it is exactly that sample size is big with external maximum difference.?
Oupatient Check-UPS, the small-sized POCT analyser of emergency treatment inspection, in analysis numerous items, using effect is unsatisfactory.Single part inspection
Survey, speed is slow, use cost is high.And large automatic biochemistry analyzer, specific protein analyser is suitable for batch detection, during startup
Between long, water consumption is big, unused time length, volume are not appropriate for the features such as big using in the clinical laboratory of Emergency call.
In existing biochemistry analyzer or specific protein analyser, transmitted light path mainly has using Lu Su lamp, then passes through
Plus grating or various optical filter are divided into different wave length, or it is that different wave length etc. is divided into using optical fiber plus various optical filter.
Utility model content
The purpose of this utility model is to provide a kind of photoelectric measurement structure of scattering transmission one, is applied to full-automatic biochemical
When analyser or specific protein analyser, the small volume of instrument, easy to operate, and testing cost is low, reliable results.
