Photochemical POCT all-in-one testing system and testing method

Abstract

The invention discloses a photochemical POCT all-in-one testing system. The system comprises a test card, a tray, an optical unit, and a bracket; the test card comprises an upper housing which is provided with a sample channel which penetrates through the interior and exterior of the test card, a lower housing which is movably connected with the upper housing, a diffusion layer which is at least partially arranged in the sample channel, and a reaction layer which is right opposite to the diffusion layer, wherein the reaction layer is provided with at least one reaction area and at least one identification module associated with the reaction area; the tray is used for supporting the test card, and the bottom of the tray is provided with a window for exposing at least partial area of the reaction layer; the optical unit comprises a light source and a receiver arranged close to the light source; the bracket is used for connecting the optical unit and driving the optical unit to move; when the light source irradiates the identification module, the light is reflected to the receiver to read the reaction area information associated with the identification module. The invention also discloses a photochemical POCT all-in-one testing method. According to the photochemical POCT all-in-one testing system and testing method of the invention, through association of the identification module and the reaction area, random coding of various types of reactions is realized, and the coding amount is increased; and a reaction result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of photochemical detection, and in particular relates to a photochemical POCT all-in-one test system and a test method. Background technique [0002] With the advancement of science and technology and the wide application of point of care testing (POCT: point of care testing) in the field of laboratory medicine, more and more detection indicators and products have been developed. Among them, optical PCOT biochemical detection products occupy an indispensable proportion in in vitro diagnostic testing, including diabetes series indicators, kidney function series indicators, liver function series indicators, blood / urine biochemical indicators, etc., made into dry chemical test strips Form, combined with supporting miniaturized detection instruments to provide fast, simple and accurate quantitative results. In terms of product form, it is mainly divided into two forms: test strips for single analyte detection a...

Problems solved by technology

During the detection process, the pump needle inside the instrument will enter the test card for multiple suction and discharge operations. The entire detection process is relatively complicated, and there are high requirements for the development of the instrument, especially the design of the liquid circuit and mechanical positioning. Require

And the design complexity of this product makes it only suitable for detecting composite indicators, such as glycosylated hemoglobin, etc.

[0008] Although there are already some integrated products on the market, their integration method is single, and flexible customization cannot be achieved, and the cost of different integrations is very high.
