Description

A kind of test strips

Technical field

The utility model belongs to fluid analysis field, especially relates to a kind of test strips.

Background technology

The concentration of determining analyte in physiological fluid plays very important effect in the time of diagnosis and treatment various diseases. Normally, physiological fluid is coated onto in test strips, then in conjunction with some electrical properties in special measuring instrument test strip or light attribute signal, analyzes the concentration of analyte in physiological fluid.

What known measuring instrument Test paper generally adopted is all naked test strips, but this test strips is pushing in the process of application of sample position and detecting position, easily there is test strips upset, the situations such as coiling and skew, thus cause occurring flase drop, undetected and test paper wasting phenomenon. In application of sample process, be naked test strips due to what adopt, sample is added to after test strips, bad if application of sample amount is grasped, and is easy to just there will be sample to overflow test strips, and waste sample, pollutes the situation of working environment, thereby threatens the healthy of staff; Between projects of test, also easily there is cross pollution, thereby affect test result.

For addressing the above problem, the patent document that Chinese patent notification number is 102590536B discloses a kind of for depositing the case of full-automatic dry chemical analyzer test-strips, and it discloses two kinds of modes and has avoided cross pollution. One, is provided with test trough in test-strips, by the ridge of being located at test trough bottom surface, test paper is maked somebody a mere figurehead, and unnecessary liquid flows in test trough; Its two, the inner some reacting holes that arrange of test trough, are separated out several independently spaces, avoid cross pollution. Entry is reacted to test paper or reagent is positioned in test trough, when use, just can ensure its test surfaces upward, test trough increases test-strips overall weight, thereby is not prone to the situations such as upset, coiling and skew.

Although scheme one can make the liquid of great quantities of spare flow into test trough, is whole piece test paper because be placed in test trough, therefore there is between adjacent detecting pad the situation of pollution mutually. This has just caused interference to measurement, affects certainty of measurement. Although and scheme two has been stopped the generation of cross pollution situation, production process is comparatively loaded down with trivial details, the detecting pad on test paper need to be cut and put into respectively corresponding reacting hole, when strengthening workload, also reduce production efficiency. And this two schemes in use all needs to keep that test strip level is placed, test surfaces upward, measuring instrument operates steadily, otherwise the unnecessary liquid leaking down can instead overflow, and pollutes working environment, affects the accuracy of measurement result.

Summary of the invention

The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, avoid cross pollution, test strips that production efficiency is high.

The technical solution of the utility model is: a kind of test strips, comprise upper cover, test paper, imbibition element and base, described upper cover and described base are connected and fixed, and be provided with successively from top to bottom test paper and imbibition element between the two, described test paper comprises substrate and is located at several detecting pads on substrate, described upper cover is arranged with some dividing plates in parallel perpendicular to length direction, upper cover is separated into several spaces by described dividing plate, each space can hold a detecting pad on substrate, and described dividing plate lower end and substrate compress laminating.

Preferably, described upper cover and base are connected together.

Preferably, described upper cover lower end, side is along its length provided with draw-in groove, and the position that base is corresponding is provided with clamping projection, and both connect and fix in cooperation.

Preferably, the length of described imbibition element and width are greater than length and the width of test paper.

Preferably, described base is gone up and is provided with uniformly some support protrusion near a side of described imbibition element along its length, and the distance between the support protrusion being oppositely arranged is less than the width of imbibition element and is greater than the width of test paper.

Preferably, described imbibition element is filter paper.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, adopt whole piece test paper to detect, without test paper is further processed, simplify manufacturing procedure, enhance productivity; Meanwhile, coordinate upper cover to use, each detecting pad is separated into independently detection space, avoid cross pollution, reduce disturbing factor, greatly improved accuracy of detection; In addition the use of imbibition element, ensures the liquid that effective filtering is unnecessary, even installing and using the situation generation that has test strips direction to change in process, also can not pollute working environment; Have simple in structurely, processing cost is low, production efficiency advantages of higher.

Detailed description of the invention

In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.

As Figure 1-3, test strips of the present utility model, comprise upper cover 1, test paper 2, imbibition element 3 and base 4, described upper cover 1 and described base 4 are connected and fixed, and be provided with successively from top to bottom test paper 2 and imbibition element 3 between the two, described test paper 2 comprises substrate 21 and is located at the some detecting pads 22 on substrate 21, described upper cover 1 is arranged with some dividing plates 11 in parallel perpendicular to length direction, upper cover is separated into several spaces 12 by described dividing plate 11, each space 12 can hold a detecting pad 22 on substrate 21, and described dividing plate 11 lower ends and substrate 21 compress laminating.

Between described upper cover 1 and base 4, be connected together. Described upper cover 1 lower end, side is along its length provided with draw-in groove 13, and the position of base 4 correspondences is provided with clamping projection 41. Between this upper cover 1 and base 4, also can bond together, can also be the connected mode that other those skilled in the art expect.

The length of described imbibition element 3 and width are greater than length and the width of test paper 2. Can effectively absorb unnecessary liquid, avoid polluting working environment, affect accuracy of detection.

Described base 4 is provided with some support protrusion 42 along its length near a side of imbibition element 3, distance between the support protrusion 42 being oppositely arranged is less than the width of imbibition element 3 and is greater than the width of test paper 2, after component assembling, can there is deformation in imbibition element 3, form small arc, thereby can more effectively adsorb unnecessary liquid.

Described imbibition element 3 is filter paper.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model. All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
