Technical field
The utility model relates to immunochromatography and detects articles for use, particularly relates to a kind of external joint inspection diagnosis test paper and kit.
Background technology
In recent decades, worldwide irritated crowd is increasing.Irritated this concept typically refers to I type hypersensitivity (type), causes symptom in contact allergy after former 30 minutes usually.The anaphylactogen that causes the hypersensitivity of I type is the protein from physical environment mostly, as plant pollen, animal skin, food, dirt mite and insect venom etc.The distinguishing feature of I type hypersensitivity is that anaphylactogen combines (sIgE) with specific immune globulin E, therefore detects the important means that sIgE becomes present anaphylodiagnosis.
Immunochromatographic method (immunochromatography) is a kind of quick diagnosis technology of abroad rising in recent years, its principle is a certain district band that special antibody is fixed in nitrocellulose filter earlier, after this dry cellulose nitrate one end immerses sample (urine or serum etc.), because capillarity, sample will move forward along this film, when moving to when antibody regional fixedly arranged, corresponding antigen namely is combined with this antibody generation specificity in the sample, if can make this zone show certain color with immune colloid gold or immuno-enzymatic dyeing, thereby realize specific immunodiagnosis.
In recent years, providing reliable, instant testing result is one of developing direction of laboratory medicine.This demand is impelled various can constantly the release at medical science detection (POCT) product that the patient carries out at one's side.The golden label immunoassay technology that early 1990s grows up has obtained using widely clinically, and the test item that relates to comprises infectious diseases antigen, antibody, tumor markers, the detection of hormone and medicine.
Existing anaphylactogen diagnostic method mainly is the detection at single anaphylactogen, as dirt mite, pollen, cat hair etc.Existing latex beads allergenic specific IgE testing product also can only detect single anaphylactogen.But only do the explanation patient's body situation that a detection can not be complete, will do multinomial detection in clinical, therefore the work that not only needs to consume a large amount of serum but also need to do a lot of repetitions demand developing a kind of product that can detect multinomial anaphylactogen simultaneously urgently.
The utility model content
The purpose of this utility model provides a kind of external joint inspection diagnosis test paper and paper box that can carry out multinomial detection simultaneously, makes the user need not much to repeat work, reduces labour intensity.
For achieving the above object, the utility model adopts following technical scheme:
A kind of external joint inspection diagnosis test paper comprises many immunochromatographydetecting detecting test strips, and described many immunochromatographydetecting detecting test strips share a sample pad.
Further, described sample pad radially, described immunochromatographydetecting detecting test strip also comprises by mark zone, nitrocellulose filter detection zone and absorbent filter district and is connected the workspace of forming successively, and each radiation band of described sample pad is connected with each bar workspace respectively.
Further, described sample pad is almost fan, and protrudes a plurality of bands in a side direction external radiation of fan-shaped arc.
Further, described sample pad one side also is provided with the pad ear of being convenient to take.
Further, the nitrocellulose filter detection zone of described many immunochromatographydetecting detecting test strips is coated with different anaphylactogens respectively, and the mark zone is coated with the anti-IgE antibodies of trace particle mark respectively.
Further, described trace particle is latex beads.
Further, described immunochromatographydetecting detecting test strip is 5.
The utility model also provides a kind of external joint inspection diagnostic kit, comprise housing, be set with aforesaid external joint inspection diagnosis test paper in the described housing, the zone of counter sample pad has well on the described housing, and also is provided with the watch window be used to the testing result that reads described immunochromatographydetecting detecting test strip on the described housing.
Further, described housing comprises loam cake and the lower cover of working in coordination, and described loam cake and/or lower cover are provided with groove or the rib for fixing described external joint inspection diagnosis test paper.
Because adopt technique scheme, the utility model has the following advantages at least:
(1) owing to adopt the version that shares sample pad, can enough realize multinomial order joint inspection, the user need not much to repeat work, has reduced user's labour intensity.
(2) owing to improved the shape of sample pad, make it radially, almost fan structure especially, multinomial visual inspection can reduce the consumption of sample when surveying.
(3) because the nitrocellulose filter detection zone of many immuno-chromatographic test paper strips is coated with different anaphylactogens respectively, can fast detecting go out the specific IgE antibody that whether contains in serum, blood plasma or the whole blood at certain anaphylactogen.
(4) owing to adopt new kit, be used for loading above-mentioned external joint inspection diagnosis test paper, a step simple to operate finishes, visual result as seen, and preserve convenient.
