Problems solved by technology

The diffusion layer, filter layer, and reaction layer of this product are stacked and in contact with each other. Before the samples are evenly diffused, some samples may have already been filtered and reached the reaction layer, which will have a certain impact on the accuracy of the reaction results.

Embodiment 1

[0048] Such as figure 1 As shown, a reaction test paper for photochemical POCT detection includes a test paper body 20, at least one reaction zone 22 formed on the test paper body 20, and at least one identification module associated with the reaction zone 22, the identification module can be with color block area 23;

[0049] Of course, at least one blank control area 21 can also be formed on the test paper body 20;

[0050] In this embodiment, there are multiple reaction areas 22 and color block areas 23, and the combination of multiple reaction areas 22 and multiple color block areas 23 is related, and each combination of multiple color blocks includes each information on the reaction zone of the test combination;

[0051] Of course, in other embodiments, the reaction area 22 is associated with the color block area 23 one by one, that is to say, the number of the reaction area 22 is the same as the number of the color block area 23, and one color block area contains the i...

Embodiment 2

[0057] Such as figure 2 As shown, a photochemical POCT all-in-one test card includes an upper housing 11, a lower housing 12 movably connected to the upper housing 11, a reaction layer 2, and a diffusion layer 3 at least partially disposed in the main body channel 111; A sample channel 111 is formed on the upper casing 11 through its thickness direction inside and outside, as Figure 10 As shown, the sample channel 111 can be provided with a filter layer 5, in order to install the filter layer 5, an installation groove 114 is formed on the lower surface of the upper housing 11, and the installation groove 114 can be concentrically arranged with the sample channel 111; the installation groove 114 The shape and size of the filter layer are adapted to the filter layer 5, so that the filter layer 5 can be tightly fitted in the installation groove 114. Of course, in other embodiments, the detection sample can be directly detected without filtering, so there is no need to set the f...

Embodiment 3

[0086] Such as Figure 9 As shown, a photochemical POCT all-in-one test system includes a test card 7, a tray 8 for supporting the test card 7, an optical unit 6 located below the tray 8, a bracket 63 for connecting the optical unit 6, and a Pressure piece 9 above the test card 7.

Abstract

The invention discloses a photochemical POCT all-in-one test card. The card comprises an upper shell, a lower shell and a diffusion layer; the upper shell is provided with a sample channel penetrating through the inside and the outside of the upper shell; the lower shell is movably connected with the upper shell and is provided with a reaction layer; at least part of the diffusion layer is arranged in the sample channel, and at least part of the diffusion layer directly faces the reaction layer; during sample diffusion, the diffusion layer is not in contact with the reaction layer, after sample diffusion is completed, the diffusion layer is in contact with the reaction layer. The sample is fully diffused and then is in contact reaction with the reaction layer, so that a reaction result is more accurate; the same system instrument can detect a plurality of different indexes, and integration of a plurality of detection indexes can be carried out more flexibly; through the association of an identification module area and a reaction area, the feasibility of any coding of various types of reactions is realized, and the coding quantity is greatly increased; the test operation is simple and easy, and the test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of photochemical detection, in particular to a photochemical POCT all-in-one test card. 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 and test strips for multiple anal...
