One, technical field
The utility model relates to a kind of hospital routine inspection instrument, specifically a kind of discrete multi-wavelength semi-automatic biochemical analyzer.
Two, background technology
Biochemical Analyzer is mainly used in the dirtization in clinical blood, the humoral sample and the fast quantitative analysis of chemical analysis, it is the routine inspection instrument of modern hospital, since first Biochemical Analyzer of nineteen sixties construction, its development is to advance by leaps and bounds.Domestic in recent years development and produce just at the early-stagely, and most semi-automatic biochemical analyzer remains and used mobile cuvette, and its analysis speed is lower, and precision is also difficult to have reached higher level.There is following shortcoming in existing flow-type semi-automatic biochemical analyzer:
1, test speed is low, end-point method be 120 the test/hour, rate method be 30 the test/hour;
2, test result poor accuracy;
3, cross pollution is arranged;
4, the test specimen amount is few, and test event is few;
5, instrument reliability is poor, and pipeline, water route are arranged, and cuvette need not have bubble for a long time;
6, the reactant liquor demand is big, require more than the 300ul, otherwise the cross pollution meeting increases because of the minimizing of reactant liquor;
7, can not show reaction overall process curve, only show the course of reaction sub-fraction.
The discrete cuvette is discrete mutually, does not have cross pollution each other, and the number of cuvette also can be placed as required, and the precision of this sampling instrument and speed will be greatly improved, and is subjected to the welcome of vast hospital deeply.
Three, summary of the invention
The purpose of this utility model provides a kind of discrete multi-wavelength semi-automatic biochemical analyzer, and this Biochemical Analyzer utilizes the discrete notion to make semi-automatic biochemical analyzer, real no cross pollution, low, the good stability of instrument failure rate realized.
The purpose of this utility model is achieved through the following technical solutions:
A kind of discrete multi-wavelength semi-automatic biochemical analyzer, comprise light source, optical fiber, cuvette, reaction tray, optical filter, photoelectric commutator and computing machine, it is characterized in that: described one group of cuvette adopts discrete to be placed on the rotating colorimetric disc, the light that light source sends becomes monochromatic light through shining on one group of cuvette and by the optical filter beam split behind the optical fiber light-guiding, incide on the optoelectronic receiver, optoelectronic receiver is connected with the computing machine that is used for carrying out data processing.
In the utility model, one group 120 the annular discretes of cuvette evenly are placed on around the colorimetric disc, and cuvette is purple organic glass cuvette.Light source is selected 35W, 12V for use, the quartz glass Halogen lamp LED, become 8 beam diameter 2.5mm directional lights behind the collimation, adopt discrete, 6mm optical path, cube structure, ultraviolet-transmitting organic glass cuvette be placed on colorimetric disc around, cuvette requires uniformity, light hole can not have any cut, accurate 120 light tanks such as code-disc such as branch such as grade are aimed at the centre position of cuvette, guarantee the middle of reading sampled point at cuvette; Colorimetric disc one circle is placed 120 cuvettes altogether, and minimum is 180ul than color tolerance liquid measure.Its advantage is not have cross pollution (as the cross pollution of the cuvette existence of flowing), and reagent dosage is economized.
The utility model adopts the discrete colorimetric, and 120 discrete purple organic glass cuvettes utilize the discrete notion to make semi-automatic biochemical analyzer.Compare with the semi-automatic biochemical analyzer that adopted the cuvette that flows in the past, the utility model has the advantages that: 1, test speed is fast, maximum analysis speed: 600 tests of end-point method/hour, 300 tests of rate method/hour; 2, test result is accurate, and the overall process response curve faced survey in 10 minutes, the accuracy of temperature control height, and test result is accurate; 3, no cross pollution; 4, fault is few, and instrument does not have any pipeline, water route; Also can not produce the cuvette bubble, the instrument failure rate is low, and stability of instrument is good.

Fig. 2 is the structural representation of colorimetric disc in the utility model.
Five, embodiment
A kind of discrete multi-wavelength semi-automatic biochemical analyzer described in the utility model, comprise light source 1, optical fiber 2, cuvette 3, colorimetric disc 4, optical filter 5 photoelectric commutators 6 and computing machine 7, one group of cuvette 3 adopts discrete to be placed on around the colorimetric disc 4, shine on one group of cuvette 3 and behind light process optical fiber 2 leaded lights that light source 1 sends and become monochromatic light by optical filter 5 beam split, incide on corresponding one group of optoelectronic receiver 6, optoelectronic receiver 6 is connected with the computing machine 7 that is used for carrying out data processing.
The test process flow process is as follows:
During test, manually sample and reagent are mixed into reactant liquor by fixed proportion, again reactant liquor are joined in the cuvette 3.Colorimetric disc 4 one circles are evenly placed 120 cuvettes.Light source 1 incides the light beam that is divided into eight beam diameter 2.5mm behind optical fiber 2 end faces, every bundle light is respectively by discrete cuvette 3, carry out beam split with optical filter 5, white light is become monochromatic light incide corresponding photoelectric commutator 6 surfaces again, photoelectric commutator 6 converts light signal to electric signal, circuit part amplifies this signal, is digital signal by the A/D conversion with analog-signal transitions.Instrument carries out colorimetric analysis according to the parameter of artificial input, and last computing machine 7 carries out computing, draws the concentration of institute's mark a certain material originally, and is reported by the printer prints result.
The photosignal transfer process is as follows:
Light source → optical fiber → cuvette → optical filter beam split → photoelectric commutator → signal amplification → A/D conversion → Computer Processing
