Description

Information acquisition device for dry chemical analysis and immunological analysis

Technical Field

The utility model relates to an information acquisition device that can be used to dry chemical analysis and immunological analysis belongs to medical instrument technical field.

Background

Point-of-care testing (POCT) refers to a method of analyzing samples immediately at a sampling site, omitting a complicated processing procedure of the samples during laboratory testing, and rapidly obtaining a test result. In recent years, with the development of high and new technology, the progress of medical science and the efficient and fast-paced working mode, POCT with the miniaturization of experimental instruments, the simplification of operation and the instantaneity of report results is more and more favored by people.

Dry chemical analysis and immunological analysis are two common methods for POCT analysis, and are currently widely used in clinical medicine.

The dry chemical analysis method is a method of directly applying a liquid test sample to a commercial dry reagent strip specifically manufactured for a different project to cause a specific chemical reaction using moisture of the test sample as a solvent, thereby performing chemical analysis. The existing dry chemical analysis method mainly adopts a reflection photometry as a measuring means, and mainly has the following advantages: the accuracy is high, the speed is high, and the inspection result can be made within 3-4 min generally; the operation is simple and convenient, and daily correction is not needed; no other reagent needs to be stored or any solution needs to be prepared; the specimen does not need to be pretreated, and the multilayer film has the function of selective filtration, so that the influence of interference substances in the determination process is reduced; the sample consumption is small, the water content in the reaction is supplied by the liquid component in the sample, and the measurement sensitivity is high; some cases can replace a wet chemistry method to be used for emergency treatment samples, and can also be used for methodological evaluation of conventional detection results and the like.

Dry chemical analysis methods are not only used for qualitative examinations, but are now developed for semi-quantitative and quantitative analysis methods, and have become an important class of methods in clinical examinations. Dry chemical analysis methods have made major advances in the qualitative examination of urine (e.g., urine protein, urine glucose, occult blood, bilirubin, urobilinogen, ketone bodies, specific gravity, nitrite, bacterial urine, etc.).

The immunological analysis method is a method for detecting toxicants by using antibodies which competitively bind the toxicants and labeled toxicants, and can be used for screening tests of certain toxicants. Detecting by using an immunological analysis method, wherein when the non-labeled toxic medicament is not added, the antibody is completely combined with the labeled toxic medicament to generate a labeled toxic medicament-antibody compound; after the non-labeled toxic medicament is added, the non-labeled toxic medicament is also combined with the antibody to generate a non-labeled toxic medicament antibody compound, so that the combination reaction of the labeled toxic medicament and the antibody is inhibited, and the content of the labeled toxic medicament in a generated product is reduced; if the amounts of the antibody and the labeled toxic drug are fixed, a certain functional relationship exists between the amount of the added non-labeled toxic drug and the content of the labeled toxic drug in the compound; and (3) selecting a proper method to detect the labeled toxic medicament in the compound, and calculating the amount of the toxic medicament in the detection material according to the amount.

The immunological analysis methods are classified from the labeling point of view and can be classified into non-labeled immunological analysis methods and labeled immunological analysis methods, wherein the non-labeled immunological analysis methods mainly comprise: immunodiffusion, immunoelectrophoresis, and the like; the labeled immunological analysis method mainly comprises the following steps: enzyme immunoassay, magnetic sensitive immunoassay, dry immunoassay (such as fluorescence immunoassay, colloidal gold immunoassay, luminescence immunoassay, ferritin immunoassay, time-resolved fluorescence, quantum dot fluorescence labeling, microfluidics, and the like), and the like. Among them, the labeled immunoassay has the characteristics of rapidness, qualitative, quantitative and even localization, and is the most extensive immunoassay method at present, such as the colloidal gold immunoassay.

The Immune colloidal gold technology (Immune colloidal gold technology) is a novel Immune labeling technology which applies colloidal gold as a tracer marker to antigen and antibody, and is abbreviated as follows in English: in GICT, colloidal gold is prepared by polymerizing chloroauric acid (HAuCl4) into gold particles of a specific size under the action of a reducing agent (such as white phosphorus, ascorbic acid, sodium citrate, tannic acid, etc.), and is in a stable colloidal state due to electrostatic interaction. The immune colloidal gold technology mainly utilizes the characteristic that gold particles have high electron density, black brown particles can be seen under a microscope at the binding site of gold-labeled protein, and red or pink spots can be seen by naked eyes when the markers are massively aggregated at corresponding ligands. When the colloidal gold is used for detection, a reflection-type photoelectric detection method is mainly adopted, compared with other labeled immunological analysis methods, the immune colloidal gold technology has the characteristics of simplicity, rapidness, accuracy, strong specificity, high sensitivity, no pollution, low false positive rate, stable reagent, no harm to human bodies and the like, only needs a common optical instrument during detection, and is widely applied to the field of medical clinical diagnosis of infectious disease pathogens, hormones, bacteria, tumor markers and the like at present.

Although dry chemical analysis methods and immunological analysis methods are widely applied to clinical medical detection due to the advantages of rapidness, convenience and the like, detection equipment used in the current dry chemical analysis methods and immunological analysis methods is generally large in size and single in function, and can only be used for detection of a single item, for example, a glucometer, a dry chemical meter, an immunological analyzer, a thyroid hormone detector and the like which are commonly used at present are not beneficial to clinical medical detection, and the application of instant detection is influenced.
