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, so that it is determined that the chemical composition of sample, color comparison tube is widely used in the detection field of environmental protection tests (as water quality of river detects), food quality detection, medical treatment detection or other industry, portable color comparison tube small volume, can be used for going out to carry, on-the-spot sample is detected, there is real-time, convenience。
Such as in many medical tests, need to mix sample to be measured with first liquid, it is easy to the interfering components in removal sample, starts the first chemical reaction or biological respinse, when sample to be detected mixes after certain time with first liquid, it is added to second liquid, start the second chemical reaction or biological respinse, if sample component to be detected is more complicated, even need to add the 3rd liquid or the 4th liquid, to start the 3rd reaction or the 4th reaction, whole process passes through its chemical reaction of photometric measurement。Such as, glycolated hemoglobin composition in test blood, need to mix the molten sample crossing blood with R1 (first liquid), destroy the composition being likely to impact test in sample, it is subsequently adding R2 (second liquid) to react again, detects finally by photometric detection device。
Photometric measurement for basic automatization, the automatic analyzer having various complexity measures, instrument to complete the application of sample of plurality of reagents, including complicated sample adding system, stirring system, purging system, heating system, cause whole instrument quite huge, complicated, price costly, and only has large hospital to be subject to special door start-up to operate；At present, existing one manually completes photometric measurement, application of sample, stirring semi-automatic biochemical analyzer, its relative volume is less, and existing semi-automatic biochemistry analyzer includes mixing container。
Color comparison tube is used for depositing and mixing sample to be detected and liquid in biochemical analysis instrument apparatus, color comparison tube includes for depositing first liquid, steel ball and the first mixing container with detection sample, for depositing the second mixing container of second liquid, when detection, mix container cover by first to take off, mix container by second and insert the first mixing upper vessel portion, and second the upper and lower of mixing container be respectively equipped with and can mix the sealing-plug that slide up and down of container inner wall second, when second liquid is mixed by needs with first liquid, the sealing-plug of the second mixing upper vessel portion is enforced by the push rod in biochemistry analyzer, thus driving the sealing-plug of second liquid and the second mixing lower vessel portion to move downward, when the sealing-plug of bottom departs from the second mixing container, second liquid mixes internal tank drippage due to gravity from second, and mix with first liquid, again through be previously positioned in the first mixing container steel ball and coordinate be independently arranged in biochemistry analyzer the dynamic first mixing container of magnetic agitation dribbling in steel ball rotate, thus mixed solution is stirred, make mixed solution react completely and stir, finally carry out photometric detection, above prior art comes with some shortcomings part:
1) for needing strict 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, second liquid is made easily to remain on inwall or the sealing-plug of the second mixing container, cause that the consumption participating in the second liquid of reaction is inaccurate, thus affecting the reaction of first liquid and second liquid, the accuracy ultimately resulting in photometric detection is not high, mistaken diagnosis or wrong report easily occurs on medical treatment detects；
2) existing color comparison tube is only only applicable to the mixing of two kinds of liquid reagents, it is impossible to carry out more than three kinds reagent tests；
3) owing to steel ball is to be encapsulated in the liquid in the first mixing container in advance, and steel ball is before being immersed in liquid, need the surface to steel ball to carry out special handling, and steel ball long period of soaking is likely to change so that the composition of liquid in liquid, and then be likely to affect the result of subsequent reactions。
