Problems solved by technology

The disadvantages are: (1) It can only detect samples qualitatively, it is difficult to realize quantitative detection of samples, and it is even more difficult to realize rapid quantitative detection of multi-component samples
(2) For some samples with extremely low antigen or antibody content, it is difficult to judge the results with the naked eye, and the detection sensitivity is low
RFID tags are small in size, large in information storage capacity, and require no manual intervention for identification. They are also an ideal means of information access and identification, but few people use them in the field of biomedical testing.

Embodiment 1

[0033] Figure 1-4 Embodiment 1 will be described. Embodiment 1 is one of the preferred schemes of the test strip card of the present invention.

[0034] Figure 1-4 In the preferred solution, the test strip card includes a cartridge 3 and a test strip 2 . The test strip 2 includes a sample suction pad 4 , a marking pad 5 , an analysis membrane 7 , and a water absorption pad 8 which are sequentially overlapped and fixed on the bottom liner 1 . The analytical membrane 7 has a detection zone 6 . One end of the cartridge 3 together with the opening on the upper surface of the cartridge end forms a test strip slot opening 12, so that the test strip 2 can be inserted into the cartridge 3 at present. The test strip 2 is a detached and plug-in structure of the cartridge 3 . When the sample is tested, one end of the sample suction pad 4 of the test strip 2 inserted into the cartridge 3 interferes and protrudes from the open end of the cartridge 3 to soak and absorb the sample. A...

Embodiment 2

[0045] Figure 5-8 Embodiment 2 will be described. Embodiment 2 is another preferred solution of the test strip card of the present invention.

[0046] Figure 5-8 In the preferred solution, the test strip card includes a cartridge 3 and a test strip 2 . The test strip 2 includes a sampling pad 4 , a marking pad 5 , an analysis membrane 7 , a water-absorbing pad 8 , and a test strip reaction end point indicating label 9 which are sequentially overlapped and fixed on the substrate 1 . The analytical membrane 7 has a detection zone 6 . One end of the cartridge 3 together with the opening on the upper surface of the cartridge end forms a test strip slot opening 12, so that the test strip 2 can be inserted into the cartridge 3 at present.

Abstract

Belonging to the in vitro diagnosis field, the invention in particularly relates to a test strip card with a storage medium (13) for storing a detected object standard curve or coefficient parameter and other information for the detection. The test strip card includes a card box (3) and a test strip (2). One end of the card box (3) is opened to form a test strip slot opening (12). The test strip (2) is a detachment plug structure of the card box (3). The storage medium (13) is mounted on the card box (3). During sample detection, one end of a sample absorbing pad (4) in the test strip (2) inserted into the card box (3) interferes and extends out of the opening end of the card box (3) to soak and absorb the sample. Then an instrument with a signal detection function collects the characteristic signal of a detection band (6) in the test strip (2). And by combining the instrument, the detected object standard curve or coefficient parameter are read at the same time from the storage medium (13), so that a sample single-component or multicomponent concentration can be calculated. The test strip card for sample detection provided by the invention has the characteristics of simplicity, rapidity, high sensitivity, subjective result, and flexible application, etc.

Description

technical field [0001] The present invention belongs to the field of in vitro diagnosis, and in particular relates to an instrument with a storage medium 13 for storing detection information such as standard curves or coefficient parameters of the tested object, combined with an instrument with a signal detection function, which can quickly detect a single component or multiple groups of samples. Score test strip card. Background technique [0002] The immunochromatographic test strip technology mainly represented by colloidal gold test strips has been widely used in various aspects of immunoassay. The technique is simple and fast, with results within minutes. The disadvantages are: (1) It can only detect samples qualitatively, but it is difficult to realize quantitative detection of samples, and it is even more difficult to realize rapid quantitative detection of multi-component samples. (2) For some samples with extremely low antigen or antibody content, it is difficult ...
