Know-why
In a specific embodiment, test-strips of the present invention only has a contact jaw, that is to say, sample is introduced into this absorbent material by the contact jaw on the absorbent material.In the another one specific embodiment, filtering layer on the test-strips and hydrophobic medium (if exist) contact with absorbent material on same test-strips.In some specific embodiments, test-strips comprises an independent absorbent material band, and on this band, absorbent material contacts with the reacting pad of filtering layer and various tracer liquid different qualities.Test-strips among the present invention also can comprise an absorbent material band, and 2 or more filtering layers and a plurality of reacting pad (hydrophobic medium is alternative to be used) and a support arranging along this absorbent material successively.Certainly according to different detection requirements, some special devices comprise a plurality of test-strips.Absorbent material is rectangle or band shape normally, but does not also influence other shape of testing result.In a specific embodiment, the test-strips among the present invention comprises at least 2 test sample reacting pads of different nature.In other specific embodiment, test-strips comprises at least 3, at least 4, at least 5, at least 6 or at least 7 reacting pads.In some specific embodiments, test-strips is generally rectangle, and filtering layer and reacting pad are equidistantly arranged along absorbent material.
Filtering layer contacts with absorbent material.In some specific embodiments, filtering layer is made of porous infiltration or fibrous material, and these materials can make sample freely flow through and arrive reacting pad.When flow of liquid was gone forward side by side into reacting pad through filtering layer, filtering layer can promote sample to distribute, thus the generation that can survey signal in the promotion reacting pad.When sample is saturated in the reacting pad, filtering layer also can stop sample from the reacting pad adverse current to absorbent material, can stop also that chemical reactant is brought to another reacting pad in downstream from a reacting pad in the reacting pad.Filtering layer can promote the sample distribution can stop the material of sample from the reacting pad adverse current to absorbent material to be made again by any.Glass mat or liner are with being very suitable in the present invention, and filter paper or the same with other material with material like the stationery also can satisfy the requirement of filtering layer in this device.
Reacting pad contains the required reagent of detection, and the surveyed signal relevant with sample characteristics of for example can be provided.In those specific embodiments, reacting pad is the test chemical pad, and these test chemical pads are very useful in the present invention.They comprise the reacting pad of " dip in sample thief and read the result " formal testing bar, particularly including soaking into chemical indicator are arranged, characteristic produces the reacting pad can survey signal per sample when carrying out analyzing and testing with it.
For example, when the present invention is used for detecting metabolin in urine of drugs or drugs, should confirm at first whether the experimenter mingles in urine for the fact of covering drug abuse.In this case, test-strips can oneself be equipped with pH, proportion, oxygenant and nitrite indicator.Whether the detection by these projects can disclose mingles, because known proportion and general mingling can demonstrate suspicious testing result on one or a plurality of reacting pad, thereby can further investigate affirmation.Reacting pad is made up of 3MM filter paper, also can use the filter paper and the material of other kind.
In the specific embodiment of other, the obstertrician can be by pH, proportion, protein, sugar and/or other specific metabolic mark of urinalysis detection paper pregnant woman urine, to find metabolism or other ma's baby problem.During physical examination, also can utilize test paper to determine whether patient's bladder is infected with detection pH, proportion, protein, reaction of blood pad.Another situation, healthy censor can detect beef with test-strips and whether be subjected to colon bacillus 0157: H7 or salmonella-polluted.With reference to the present invention, other field that present technique field those of ordinary skill can be associated and the reacting pad knob that important information can be provided in these fields close, and all belong to scope of the present invention.
Support provides protection for test-strips.In a specific embodiment, support has viscosity also can be with each ingredient of test-strips, and for example absorbent material, filtering layer, hydrophobic medium (if existence) and reacting pad grind and lump together.Support can be made with any suitable material, can observe reacting pad as long as see through it.In some specific embodiments, support is transparent adhesive tape.Support can any suitable manufacture (such as on bar bag or color spray etc.) apply to test-strips.For example, on test-strips, spray the effect that waterproof paint clearly or ink can play the protection test-strips, and each layer component of test-strips can be rolled together.
When first of test-strips terminal contact with fluid sample, liquid makes by capillarity mobile to second end of test-strips along absorbent material.When sample arrived filtering layer, a part of sample entered reacting pad by filtering layer, and remaining sample continues second terminal the moving to test-strips.The material of filtering layer (as glass fibre) can stop liquid from the reacting pad adverse current to absorbent material.
The theory that skim is special, flowing of liquid generally can be flowed along " loop " direction: promptly enter reacting pad by filtering layer from absorbent material, then from reacting pad again after filtration laminar flow get back to the absorbent material.Design of the present invention can effectively stop liquid to be back to absorbent material, makes testing result clearer, also can make fluid sample can not make the result fuzzy by the time lengthening of test-strips.
Because if can keep the longer time, then test-strips can assembly reaction pad as much as possible, but still can produce clear and legible testing result in absorbent material for fluid sample.When fluid sample entered reacting pad, the analyte that exists in reagent in the reacting pad and the sample reacted and produces the signal surveyed that shows testing result.These reagent also can with fluid sample reaction to determine the character (for example physical propertys such as pH value or proportion) of sample. " reagent " refers to and reacts with sample and can produce the chemical substance that can survey signal demonstration testing result.Can survey signal can compare with standard, and a specific embodiments is that can survey signal is the change of color on the reacting pad, by determining testing result with standard scale or the comparison of card color.Standard scale or cartoon cross color indication positive and or negative result, perhaps provide the quantitative level ground that is associated with testing result to estimate.To measure pH is example, and in a specific embodiment, it is cream-coloured (giving an example) that reacting pad begins, and with the sample yellowing that reacts, the result shows pH value low (acidity); Become blueness if (giving an example) reacts with sample, the result shows pH value high (alkalescence); The color that produces on the reacting pad as yellow green or blue-green, shows that then the result is neutral between yellow and blueness.
Judge by pH value or creatinine numerical value in the mensuration urine whether urine is mingled.
1、PH。Normal urine PH is 4.5-8.0, is lower than 4.0 or be higher than 9.0 and be and mingle.
2, a day drainage creatinine is measured relevant, normally constant with the human muscle.The urine sample explanation urine that is lower than 5mg/ml is replaced.Though creatinine concentration is subjected to age, sex, body weight, muscle mass, local population distribution influence, the urine sample that is lower than the concentration of 20mg/ml can think that urine is diluted.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
