Abstract
The utility model provides a novel detecting test paper for colloidal gold and relates to the field of clinical medicine inspection. The novel detecting test paper for colloidal gold comprises a substrate (1) and a water-absorbing paper (6) and is characterized in that: an upper layer sample pad (2), a lower layer sample pad (3), a glass cellulose membrane (4), a nitrocellulose membrane (5) and the water-absorbing paper (6) are attached to the substrate and are tightly connected in turn from left to right; the upper layer sample pad (2) and the lower layer sample pad (3) are stacked together; the glass cellulose membrane (4) is wrapped with a colloidal gold labeled antibody; and the colloidal gold labeled antibody wrapped on the glass cellulose membrane (4) is located at the left end of the glass cellulose membrane (4). The novel detecting test paper provided by the utility model can effectively stop red blood cells so as to cause antigens to fully combine with the colloidal gold labeled antibody, the spreading layer is more uniform and the flexibility is higher.
Description
Technical field
The utility model belongs to the clinical medical inspection field, is specifically related to change the quantity of sample pad and the new colloidal gold test strip of colloid gold label antibody location.
Background technology
Colloidal gold kit is quick, easy because of it, and visual result and being used widely has critical role in POCT (Point-Of-Care Testing) technology in modern times.The colloidal gold colloidal gold detection test paper strip that prior art provides, sample pad is generally one deck, and the colloid gold label antibody location generally overlaps on together at the right-hand member and the nitrocellulose filter of polyester film.It is inhomogeneous that antigen-Jin labeling antibody combination will inevitably appear in such colloidal gold colloidal gold detection test paper strip, a coated film exhibition layer heterogeneity, and sensitivity is not high, and when the dropping sample is whole blood, can not stop problems such as red blood cell effectively.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists; The utility model provides a kind of quantity of sample pad and new colloidal gold test strip of colloid gold label antibody location of changing; This test strips can stop red blood cell effectively, and more homogeneous, sensitivity are higher to make antigen and colloid gold label antibody fully combine, open up layer.
The technical scheme that the utility model topic is adopted is: the utility model provides a kind of new colloidal gold test strip; Comprise end liner and thieving paper; Attached to what from left to right closely link to each other successively on the end liner is upper strata sample pad and the lower floor's sample pad that is stacked together, the plain film of spun glass, nitrocellulose filter and the thieving paper that is coated with colloid gold label antibody, and the colloid gold label antibody that encapsulates on the plain film of spun glass is positioned at the plain film left end of spun glass.
Said lower floor sample pad length is 1/3rd to 4/5ths of upper strata sample pad.
The material of said upper strata sample pad is the plain film of polyester film or spun glass.
The material of said lower floor sample pad is plain film of polyester film, spun glass or whole blood filter membrane.
The utlity model has following beneficial effect:
1, the utility model has solved in traditional colloidal gold strip whole blood diagnostic procedure and can not effectively stop erythrocytic problem through increasing sample pad quantity.
2, the utility model makes antigen and colloid gold label antibody response time more abundant through adjustment colloid gold label antibody location, has improved sensitivity, opens up more homogeneous of layer simultaneously.

Wherein, 1, end liner; 2, upper strata sample pad; 3, lower floor's sample pad; 4, the plain film of spun glass; 5, nitrocellulose filter; 6, thieving paper; 7, colloid gold label antibody.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2; A kind of new colloidal gold test paper strip comprises end liner 1 and thieving paper 6; Attached to what from left to right closely link to each other successively above the end liner 1 is upper strata sample pad 2 and the lower floor's sample pad 3 that is stacked together, the plain film 4 of spun glass, nitrocellulose filter 5 and the thieving paper 6 that is coated with colloid gold label antibody 7, and the colloid gold label antibody 7 that encapsulates on the plain film 4 of spun glass is positioned at plain film 4 left ends of spun glass.
Said lower floor sample pad 3 length are 1/3rd to 4/5ths of upper strata sample pad 2.
The material of said upper strata sample pad 2 is the plain films of polyester film or spun glass.
The material of said lower floor sample pad 3 is plain film of polyester film, spun glass or whole blood filter membrane.
The making of the utility model colloidal gold strip:
In dry indoor temperature 20
oC-25
oC, relative humidity<30%, from left to right paste upper strata sample pad 2 and the lower floor's sample pad 3 that is stacked together, the plain film 4 of spun glass, nitrocellulose filter 5 and the thieving paper 6 that is coated with colloid gold label antibody 7 above the end liner 1 successively; Collaurum coated antibody 7 is positioned at the left end of the plain film 4 of spun glass; Plain film 4 left ends of spun glass are covered under lower floor's sample pad 3 half territories; 1～1.5mm zone, nitrocellulose filter 5 left sides is covered in the following of the plain film 4 of spun glass, and its right side is covered in thieving paper 160th zone down, is cut into the test strips of specified width, which width at last with cutting machine, test strips is contained in the plastic clip get final product.
The utility model has changed the colloid gold label antibody location, and promptly collaurum coated antibody 7 is positioned at plain film 4 left ends of spun glass, this make antigen and antibody response time more fully, layer more homogeneous and sensitivity are higher in exhibition.
The utility model has increased sample pad quantity, has improved red blood cell obstruction rate, makes that the whole blood diagnosis is more accurate.
The above; It only is the utility model preferred implementation; Be not to be the restriction to other form of the utility model, any professional and technical personnel of being familiar with possibly utilize the technology of above-mentioned announcement can hold the equivalent embodiment that changes or be modified as equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
