Description
Technical field
The present invention relates to sample detection field, is specifically a kind of many reagents ratios colour tube for portable colorimetric device.
Background technology
At present, colorimetric cylinder is applied to sample chemical analysis and detects, by instrument, photometric detection is carried out to reacted colorimetric cylinder, thus determine the chemical composition of sample, colorimetric cylinder is widely used in environmental protection tests (as water quality of river detects), food quality detects, medical treatment detects or the detection field of other industry, portable colorimetric cylinder small volume, can be used for going out to carry, the sample at scene is detected, there is real-time, convenience.
Such as in many medical tests, sample to be measured is needed to mix with first liquid, be convenient to the interfering components in removal sample, start the first chemical reaction or biological respinse, when sample to be detected is with after first liquid mixing certain hour, add second liquid wherein, start the second chemical reaction or biological respinse, if when sample component to be detected is more complicated, even need interpolation the 3rd liquid or the 4th liquid, to start the 3rd reaction or the 4th reaction, whole process is by its chemical reaction of photometric measurement.Such as, glycosylated hemoglobin composition in test blood, need mix the molten sample crossing blood with R1 (first liquid), destroy the composition that may affect test in sample, then add R2 (second liquid) to react with it again, detect finally by photometric detection device.
For the photometric measurement of basic automation, the automatic analyzer of various complexity is had to measure, instrument will complete the application of sample of plurality of reagents, comprise complicated sample adding system, stirring system, purging system, heating system, cause whole instrument quite huge, complicated, price costly, and only has large hospital could operate by special door start-up; At present, existing one manually completes photometric measurement, the semi-automatic biochemical analyzer of application of sample, stirring, and its relative volume is less, and existing semi-automatic Biochemical Analyzer comprises mixer.
Colorimetric cylinder in biochemical analysis instrument apparatus for depositing and mixing sample to be detected and liquid, colorimetric cylinder comprises for depositing first liquid, steel ball and band detect the first mixer of sample, for depositing the second mixer of second liquid, when detecting, first mixer lid is taken off, second mixer is inserted the first mixer top, and the upper and lower of the second mixer is respectively equipped with the sealing-plug that can slide up and down at the second mixer inwall, when second liquid mixes with first liquid by needs, the sealing-plug on the second mixer top is enforced by the push rod in Biochemical Analyzer, thus drive the sealing-plug of second liquid and the second mixer bottom to move downward, when the sealing-plug of bottom departs from the second mixer, second liquid is because gravity is from the second mixer inside drippage, and mix with first liquid, again by be placed in advance steel ball in the first mixer coordinate in Biochemical Analyzer independent arrange the steel ball that moves in the first mixer of magnetic agitation dribbling rotate, thus mixed solution is stirred, mixed solution is reacted completely and stirs, finally carry out photometric detection, above prior art comes with some shortcomings part:
1) for needing strictly to control with the consumption and ratio of the aitiogenic first liquid of sample and second liquid, and above by promoting sealing-plug thus realizing the mode that first liquid mixes with second liquid, on the inwall making second liquid easily remain in the second mixer or sealing-plug, cause the consumption of the second liquid participating in reaction inaccurate, thus affect the reaction of first liquid and second liquid, finally cause the accuracy of photometric detection not high, on medical treatment detects, easily occur mistaken diagnosis or wrong report;
2) existing colorimetric cylinder is only only applicable to the mixing of two kinds of liquid reagents, can not carry out more than three kinds reagent tests;
3) because steel ball is encapsulated in the liquid in the first mixer in advance, and steel ball is being immersed in before in liquid, need to carry out specially treated to the surface of steel ball, and steel ball long period of soaking may make the composition of liquid change in liquid, and then the result of subsequent reactions may be affected.
