Description
Technical field
The present invention relates to sample detection field, be especially a kind of many reagent color comparison tube for portable colorimetric device.
Background technology
At present, color comparison tube is applied to sample chemical analysis detection, by instrument, reacted color comparison tube is carried out photometric detection, from
And determining the chemical composition of sample, color comparison tube is widely used in environmental protection tests (as water quality of river detects), food quality detection, doctor
Treat detection or the detection field of other industry, portable color comparison tube small volume, can be used for going out to carry, on-the-spot sample is entered
Row detection, has real-time, convenience.
Such as in many medical tests, needing to mix sample to be measured with first liquid, the interference being easy to remove in sample becomes
Part, start the first chemical reaction or biological respinse, when sample to be detected mixes after certain time with first liquid, be added to
Second liquid, starts the second chemical reaction or biological respinse, if sample component to be detected is more complicated, even needs to add the 3rd liquid
Body or the 4th liquid, in order to starting the 3rd reaction or the 4th reaction, whole process passes through its chemical reaction of photometric measurement.Such as, test
Glycolated hemoglobin composition in blood, need to mix the molten sample crossing blood with R1 (first liquid), destroy in sample and may impact survey
The composition of examination, is subsequently adding R2 (second liquid) and reacts, detect finally by photometric detection device.
For the photometric measurement of basic automatization, the automatic analyzer of various complexity is had to measure, instrument plurality of reagents to be completed
Sample-adding, including complicated sample adding system, stirring system, purging system, heating system, causes whole instrument the hugest, multiple
Miscellaneous, costly, and only large hospital could operate price by special door start-up；At present, existing one passes through hands
Having moved photometric measurement, the semi-automatic biochemical analyzer be loaded, stirred, its relative volume is less, existing semi-automatic biochemical
Analyser includes mixing container.
Color comparison tube is for depositing and mixing sample to be detected and liquid in biochemical analysis instrument apparatus, and color comparison tube includes for depositing
The first of first liquid, magnetic bead and band detection sample mixes container, is used for depositing the second mixing container of second liquid, works as detection
Time, the first mixing container cover is taken off, the second mixing container is inserted the first mixing upper vessel portion, and second mixes the upper of container
Portion and bottom are respectively equipped with the sealing-plug that can slide up and down at the second mixing container inner wall, when needs are by second liquid and first liquid
During mixing, enforced the sealing-plug of the second mixing upper vessel portion by the push rod in biochemistry analyzer, thus drive second liquid
Move downward with the second sealing-plug mixing lower vessel portion, when bottom sealing-plug depart from second mixing container time, second liquid by
In gravity from the second internal drippage of mixing container, and mix with first liquid, then by being previously positioned at magnetic in the first mixing container
Pearl coordinate in biochemistry analyzer be independently arranged the magnetic agitation dribbling magnetic bead that moves in the first mixing container rotate, thus to mixing
Solution is stirred, and makes mixed solution reaction completely and stir, finally carries out photometric detection, and above prior art exists one
A little weak points:
1) it is used for first liquid aitiogenic with sample and the consumption of second liquid and ratio needs strictly to control, and above by
Promote sealing-plug thus realize the mode that first liquid mixes with second liquid so that second liquid easily remains in the second mixing to be held
On the inwall of device or sealing-plug, cause the consumption participating in the second liquid of reaction inaccurate, thus affect first liquid and the second liquid
The reaction of body, the accuracy ultimately resulting in photometric detection is the highest, mistaken diagnosis or wrong report easily occurs in medical treatment detection；
2) existing color comparison tube is only only applicable to the mixing of two kinds of liquid reagents.
Summary of the invention
