Abstract
The utility model discloses a colloidal gold fast measuring device, wherein a cabinet is internally provided with a light source, a scan device, a signal process system, the cabinet is further provided with an output system and a hole for an reagent card, the reagent card is adhered with a colloidal gold immune chromatographic analysis reagent tape and is arranged on a scan device from the hole of the cabinet, a light source irradiates the reagent tape, and light signals diffusedly reflected by the reagent card are collected by the signal collection system, converted into electrical signals by the signal process system, and then output by the output system. The utility model employs the infraction principle to quantitatively detect the colloidal gold immune reagent. The incidence light passes through fiber vertically, and the diffuse reflection light is collected to detector surface by the fiber. To test the colloidal gold immune chromatographic analysis reagent by employing the diffuse reflection principle, the personal errors caused by eye observation are avoided, the detection precision is enhanced, further, compared with homogeneous devices adopting mirror reflection principle, the stability is high.
Description
Technical field
The utility model relates to a kind of clinical medicine pick-up unit, particularly a kind of collaurum fast measuring instrument that can be used for colloidal gold immunochromatographimethod reagent detection by quantitative.
Background technology
Colloidal gold immunity chromatography (GICA) is a kind of quick clinical diagnosis technology that rose in recent years, is widely used in clinical detection.At present, adopt the GICA method to carry out clinical detection and mainly rely on range estimation, i.e. the shade of surveying detection line on the colloidal gold immunochromatographimethod reagent strip is observed in personnel selection, can only accomplish to qualitatively judge, and personal error is big, causes the false retrieval erroneous judgement easily.Also there are several companies to release colloidal gold immunochromatographimethod reagent detection by quantitative device, but all adopt the direct reflection principle, be about to incide light and the light comparison of line direct reflection after testing on the detection line, judge the concentration of certain material composition in the sample with this.Because the detection line on the colloidal gold immunochromatographimethod reagent strip is not smooth plane, therefore, the light of line reflection is based on diffuse reflection after testing, and specular light only accounts for small part.Come detection by quantitative colloidal gold immunochromatographimethod reagent to exist precision low equally with the direct reflection principle, deficiencies such as instability.
The utility model content
The collaurum fast measuring instrument that provides a kind of accuracy of detection high is provided the purpose of this utility model.
For achieving the above object, solution of the present utility model is: a kind of collaurum fast measuring instrument, wherein: in cabinet, be provided with light-source system, scanister, signal acquiring system, signal processing system; On cabinet, be provided with output system, on cabinet, offer reagent card in addition and place mouth; Be pasted with the colloidal gold immunochromatographimethod reagent strip on this reagent card; Reagent card places on the scanister from the placement mouth of cabinet, shines this reagent strip by light-source system, gathers through the irreflexive optical signals signal acquiring system of reagent strip, converts electric signal to and is handled the back and exported by output system by signal processing system.
Described light-source system is made up of LED and incident light Transmission Fibers; And driving a slide plate by a stepper motor, scanister forms; Signal acquiring system is made up of reflected light Transmission Fibers and detector; Output system comprises LCD, printer and output driving circuit.
After adopting such scheme, the utility model is to adopt diffuse reflection principle, detection by quantitative colloidal gold immunochromatographimethod reagent.Incident light is by optical fiber light-guiding, and vertical incidence diffuses and collects detector surface by optical fiber.Adopt diffuse reflection principle detection by quantitative colloidal gold immunochromatographimethod reagent, avoid estimating the personal error of being brought, improve accuracy of detection; Than the same quasi-instrument that adopts the direct reflection principle to detect, degree of stability height.
