Abstract
The utility model discloses a fluorescence immunochromatography assisting device which is of a box body structure consisting of an upper cover and a lower cover which are fastened together, wherein a support slot and a support column are arranged on the lower cover and used for fixing a test strip in a suspended manner, and a pressing column is arranged on the upper cover, is opposite to a sample pad of the test strip, and pushes against the sample pad end of the test strip for a certain slope. According to the fluorescence immunochromatography assisting device, since the test strip is fixed in a suspended manner, the test strip is maximally protected from being damaged due to outside pressure; through a design that the sample pad end of the test strip has a certain slope, the chromatography speed and the sample storage amount of a sample are more effectively controlled; and through an arc-shaped protection structure, the influence of outside light on fluorescence particles is maximally avoided.
Description
Technical field
The utility model discloses a kind of fluorescence immune chromatography servicing unit, divides by International Patent Classification (IPC) (IPC) to belong to external diagnosis reagent detection technique field, especially relates to a kind of immuno-chromatographic test paper strip by the fluorescent material mark and installs and fixes box device.
Background technology
The immuno analytical method development is existing one-hundred-year history so far, wherein immunochromatographic method (being commonly called as test strips) has characteristics such as directly perceived, quick, easy and simple to handle, that expense is cheap, test solution to be measured can be blood, urine, saliva etc., and therefore the application development in use in places such as quick clinical diagnosis is rapid.Recently, based on the detection mode of fluorescence since its can be quantitatively and sensing range big, it uses more and more widely.Test strips is installed in a kind of plastic casing of flat rectangular parallelepiped usually, puts into the Card Reader instrument again and detects.Yet fixedly many shortcomings are done in the existence of the working of plastics of test strips at present: after well added sample, sample flow velocity on test strips was fast, can not control the sample reaction velocity, and easy spilling water, and the fluorescent material on the test strips is subjected to extraneous illumination effect easily.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of fluorescence immune chromatography servicing unit rational in infrastructure.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of fluorescence immune chromatography servicing unit, be to be fastened by loam cake and lower cover to form box body structure, under cover to be provided with and support draw-in groove and support column and be used for fixedly test strips and make it unsettled, the sample pad place that loam cake faces test strips is provided with down compression leg, and it presses on test strips sample pad end and is constant slope.
Further, the loam cake label pad and the membrane junction place that face test strips is provided with down the compression leg baffle plate.
Further, loam cake faces sample pad and the label pad intersection is provided with down the compression leg baffle plate.
Further, described loam cake is provided with the arcuation backplate and is positioned at the test strips both sides in test strips fluorescent material section.
Further, be covered with well on described, this well is positioned at test strips one side and forms the orifice structure with buffering.
Further, the test strips thieving paper end of described loam cake is provided with sharp compression leg to prevent the thieving paper perk.
The utlity model has following beneficial effect:
(1), the utility model is by the fixedly unsettled design of test strips, protect test strips not to be subjected to ambient pressure to a greater extent and destroy;
(2), the utility model is the design of constant slope by test strips sample pad end, more effectively controls sample chromatography speed and sample size;
(3), the utility model is provided with compression leg baffle plate down at test strips label pad and membrane junction place, be provided with compression leg baffle plate down in sample pad and label pad intersection, the flow velocity of more effective control sample is avoided the sample spilling water;
(4), the circular-arc protection structure that is provided with of the utility model avoids ambient light according to the influence to the fluorescent grain thing to a greater extent.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: see also Fig. 1 to Fig. 5, a kind of fluorescence immune chromatography servicing unit, be to be fastened by loam cake 1 and lower cover 2 to form box body structure, on, lower cover 1,2 four jiaos and middle both sides have card post 100 and post hole 200 to fasten to link to each other, be provided with at lower cover 2 and support draw-in groove 21 and support column 22 and be used for fixedly test strips and make it unsettled, the position, sample pad place that loam cake 1 faces test strips is provided with down compression leg 11, and it presses on test strips sample pad end and is constant slope, loam cake 1 is provided with arcuation backplate 12 in test strips fluorescent material section, 13 and be positioned at the test strips both sides, described loam cake 1 is provided with well 14 and detects form 16, and this well 14 is positioned at test strips one side and forms the orifice structure 140 with buffering.On be covered with twice compression leg baffle plates respectively facing to label pad and membrane junction place and sample pad and the label pad intersection of test strips.
The utility model structure and act on as follows: (1) protection test strips is avoided extraneous squeeze and destroy.(2) test strips is reacted by designing requirement.(3) avoid fluorescent material to be subjected to the influence that ambient light such as shines at factor.(4) this flow velocity on test strips of the controlled sample preparation of the baffle plate on the working of plastics is avoided the sample spilling water.(5) design of well, and the following compression leg at sample pad place, make test strips sample pad end be constant slope, sample adding fashionable can be at sample pad gradient place buffering and stored samples solution, controlled this reacting dose of sample preparation also makes sample can continue chromatography on the reaction film.(6) working of plastics lower cover support draw-in groove can make test strips unsettled, avoids in the test strips course of reaction owing to sample size is overflow to working of plastics greatly.The sharp compression leg 15 of the thieving paper end that (7) covers on the working of plastics prevents the thieving paper perk, guarantees effective connection of intersection between thieving paper and the film.
The circular arc of the utility model loam cake or arcuation part, main characteristics are to avoid fluorescence to be subjected to external interference, as support column or support draw-in groove, avoid upper and lower covers to be subjected to ambient pressure and are urged to test strips.The utility model avoids ambient light according to the influence to the fluorescent grain thing to a greater extent; More effectively control sample chromatography speed and sample size; Protect test strips to avoid ambient pressure and destroy to a greater extent.
The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
