Abstract
The utility model relates to a colloidal gold detecting test paper strip with an air-hole protecting shell, belonging to a medical testing material and comprising a flat-long protecting shell with a hollow layer; and the flat-long protecting shell is divided into three parts in the length direction from one end to the other end, namely, a hand-held end, a window and a sampling hole. The colloidal gold detecting test paper strip is characterized in that the hand-held of the flat-long protecting shell is provided with air holes. When in detection, the colloidal gold detecting test paper strip guarantees that a reaction film plays a role in capillary action normally, leads the object to be detected to be capable of completely and fast moving to the end with the air holes in a fixed direction, avoids the phenomenon of retardation or incomplete mobility, and guarantees sensitivity, accuracy and high efficiency of detection.
Description
Technical field
The utility model design field of biological detection particularly relates to the colloidal gold colloidal gold detection test paper strip of being with the bleeder vent containment vessel.
Background technology
Immune colloidal gold technique (Immunogold labelling techique) is the solid phase labelling immunoassay that grows up after fluorescein, radioactive isotope and enzyme three big labelling techniques the eighties in last century.This technology has mainly utilized gold grain to have the characteristic of high electron density, when these labels are assembled in a large number at corresponding part place, forms macroscopic redness or pink spot, thereby is used for qualitative or semiquantitative tachysynthesis detection method.Fast diagnose test paper bar is a novel vitro diagnostic techniques that has grown up on monoclonal antibody technique, colloidal gold immunochromatographimethod technology and novel chromatographic material basis since the nineties in 20th century, development in recent years is rapid, has particularly obtained widespread use in the medical test at biomedical sector.This technology mainly is that specific antigen or antibody are fixed on the nitrocellulose membrane with ribbon, colloid gold label reagent is adsorbed on the pad, be added on the sample pad of test strips one end when testing sample after, move forward by capillary action, react to each other behind the colloid gold label reagent on the dissolving pad, when moving to fixing antigen or antibody regions again, the specificity combination takes place with it and is trapped in determinand gold marked reagent compound, colloid gold label accumulates in to detect and is with, can be by the range estimation result that developed the color intuitively.Free label is then crossed and is detected band, thereby reaches and detect the purpose that thing separates automatically.
Chang Yong test strips is made of reaction film and the shell with hollow layer in the market, reaction film places hollow layer to go out, there is a well at the absorption of sample pad place of corresponding reaction film on the one side of shell, there is form at the detecting pad place, well is positioned at an end of test strips, form generally is in the centre of test strips, test sample is dripped behind well, under the capillarity of reaction film, test sample is to the directed swimming of the other end of test strips, during through detecting pad, antigen of fixing on the detecting pad or the target molecules in the antibody capture test sample, all the other materials continue to move forward, the shell of present test strip, the application of sample nose end the right other end be generally Seal Design, be convenient to that hand-held test strips is operated and not detected liquid is infected with, but because the hollow layer gap is very narrow, the detection liquid translational speed that this and extraneous disconnected design of sealed end usually influences on the reaction film is unhappy, find also that sometimes detecting the thing incapability moves to sealed end fully, thereby influenced the sensitive and accurate property and the efficient that detect.
The utility model content
The utility model provides the colloidal gold colloidal gold detection test paper strip of band bleeder vent containment vessel according to the common structural defective that exists of test strip commonly used at present.
The colloidal gold colloidal gold detection test paper strip of band bleeder vent containment vessel; comprise prolate type containment vessel with hollow layer; described prolate type containment vessel is divided into three parts from an end to the other end in the longitudinal direction: handheld terminal; form; well; it is characterized in that, have bleeder vent on the handheld terminal of described prolate type containment vessel.
Described bleeder vent and described well, form are in together on the one side of prolate type containment vessel.
Described bleeder vent is a plurality of, is fan-shaped array.
The utility model provides a kind of colloidal gold colloidal gold detection test paper strip with the bleeder vent containment vessel; comprise prolate type containment vessel with hollow layer; its characteristics are to have opened bleeder vent at the handheld terminal of containment vessel; though make that the hollow layer gap is very narrow but can keep air-flow identical with the external world; when detecting; the assurance reaction film is normally brought into play capillarity; make detect thing can be fully apace orientation move to ventilative nose end; avoid phenomenons such as retardance or incomplete swimming, guaranteed the sensitivity, accuracy and the high-level efficiency that detect.In the utility model, bleeder vent can be opened any position at the containment vessel handheld terminal, keeps hollow layer and extraneous air-flow unobstructed as long as can play.
The utility model preferably bleeder vent is opened with the same one side of well and form on.Control detects liquid and comes out to dye on operating personnel's the skin from the bleeder vent water clock.
The further preferred bleeder vent of the utility model is several apertures, is fan-shaped array.The design of a plurality of apertures makes air hole both play the effect of ventilation, can not allow reaction film come out again, thereby avoids polluteing people's skin.Fan-shaped array is comparatively attractive in appearance.

Embodiment
As shown in Figure 1; the colloidal gold colloidal gold detection test paper strip of the utility model band bleeder vent containment vessel; comprise prolate type containment vessel 1 with hollow layer; described prolate type containment vessel 1 is divided into three parts from an end to the other end in the longitudinal direction: handheld terminal 4; form 3; well 2; it is characterized in that; have bleeder vent 5 on the handheld terminal 4 of described prolate type containment vessel; though making that the hollow layer gap is very narrow, bleeder vent can keep air-flow identical with the external world; when detecting; reaction film in the assurance hollow layer is normally brought into play capillarity; make detect thing can be fully apace orientation move to handheld terminal, avoided retardance or incomplete phenomenon such as swimming, guaranteed the sensitivity that detects; accuracy and high-level efficiency.
The utility model is preferably opened bleeder vent 5 and well 2 and form 3 on same one side.Preventing to detect liquid comes out to dye on operating personnel's the skin from bleeder vent 5 water clocks.
The further preferred bleeder vent 5 of the utility model is several apertures, is fan-shaped array, as shown in Figure 1.The design of a plurality of apertures makes air hole both play the effect of ventilation, can not allow reaction film come out again, thereby avoids polluteing people's skin.Fan-shaped array is comparatively attractive in appearance.
