Description
Technical field
The utility model relates to medical in-vitro diagnosis equipment technical field, more particularly, relates to a kind of test strips and drenches sample groove and mummification analyser.
Background technology
In the in-vitro diagnosis equipment of current employing test strips, the mode of test strips and sample process has three classes.
First kind processing mode is to adopt precision syringe control point sample amount, directly by point one after another drop of sample on projects Test paper pad that is attached to test strips.It is simple in structure that such processing mode adopts, with can before and after the sampling needle that moves up and down coordinate precision syringe can complete point sample work, and owing to being one by one sample to be added on each test paper pad, avoided the mutual pollution between test paper pad.
But, the first kind adds sample loading mode and also has a lot of defects, the first, singly application of sample makes instrument increase many mechanical actions, thereby reduce detection speed, in addition, permanent application of sample causes mechanical wear to affect sample needle positioning precision, thereby so that urine be not added to and on test paper pad, affect result.
The second, point sample adds in sample loading mode for reference mark is to the urine specimen amount on each test paper pad, its sample needle aperture is very little (0.6mm is following) all, to so little needle tubing aperture, produce and often cause sample needle obstruction to cause instrument cisco unity malfunction owing to having crystallization in urine, or cause application of sample inhomogeneous, cause part test paper pad sample size to produce not false negative.
Three, all there is certain error in the location of sample needle and test paper travelling belt, and this error may cause sample can not accurately join the center of each test paper pad, thereby cause test paper pad reaction inhomogeneous, insufficient, causes result error.
Four, in actual clinical trial, find, density, the viscosity of everyone sample are different, and different samples may cause sampling needle to hang water, drips the phenomenon of not getting off, and causes leak source, and even the serious consequence of erroneous judgement appears in part test item.
Equations of The Second Kind processing mode is to adopt precision syringe control to drench sample, and sample is drenched in the test strips in disposable test paper groove, and this disposable test paper groove inside has a small amount of sample cushion space, can add more sample than point sample mode.
This kind of processing mode processing is simple in structure, can reduce to a certain extent leak source sample, adopts disposable test paper groove simultaneously, does not need to carry out the cleaning of test paper groove.
But, because disposable test paper groove inner space is limited, in the time that sample is too many, there will be and overflow, very little time, there will be again the inadequate problem of sample of drenching.In actual clinical trial, while drenching sample, sample can not be continual linear water column always and drenched from test strips top, and due to the difference of different sample viscosity, thereby some project testing piece drenches sample, insufficient to react bad test result inaccurate; It is too much that some project testing piece drenches sample, in the time detecting, also has sample liquid on test block, forms moisture film reflective, can not identify real color, and result is inaccurate.
The 3rd class processing mode adopts and directly sample is immersed in and sample is housed in vitro, then takes out test strips, and test strips is passed to test section.This kind of processing mode processing is simple in structure, without leak source.
But, in actual clinical trial, test strips has certain length, ensure that it is soaked completely, must ensure that sample size must be many, uncontrollable in practical operation, do not know whether be dipped into completely, if test strips is not soaked completely, will cause some project of top result to be forbidden.Soak while taking out test strips, in test strips, had residual sample more, can be unrestrained everywhere, affect the health of instrument etc.
Therefore, how ensureing that the reaction of test strips is accurately abundant, to improve detection accuracy, is current those skilled in the art's problem demanding prompt solution.
