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

Embodiment 1

[0034] 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.

[0035] Figure 1-4In 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 8 and a water-absorbing pad 9 which are sequentially overlapped and fixed on the substrate 1 . The analytical membrane 8 has a detection zone 6 and a quality control zone 7 . One end of the cartridge 3 forms a test strip slot opening 13 together with the opening on the upper surface of the cartridge end, 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 absor...

Embodiment 2

[0047] Figure 5-8 Embodiment 2 will be described. Embodiment 2 is another preferred solution of the test strip card of the present invention.

[0048] 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 sample-absorbing pad 4 , a marking pad 5 , an analysis membrane 8 , a water-absorbing pad 9 , and a test strip reaction end point indicating label 10 , which are sequentially overlapped and fixed on the substrate 1 . The analytical membrane 8 has a detection zone 6 and a quality control zone 7 . One end of the cartridge 3 forms a test strip slot opening 13 together with the opening on the upper surface of the cartridge end, 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 .

Abstract

The invention belongs to the field of in-vitro diagnosis, and particularly relates to a test strip card which is provided with a storage medium (14) for storing a tested object standard curve, coefficient parameters or other detection information. The test strip card comprises a card box (3) and a test strip (2), wherein one end of the card box (3) is open to form a test strip slot (13), and the test strip (2) is in a card box (3) instant-plug structure; and a storage medium (14) is installed on the card box (3). When detecting a sample, one end of a shape suction pad (4) of the test strip (2) inserted into the card box (3) excessively protrudes out of the open end of the card box (3) so as to impregnate and absorb the sample, and an instrument with signal detection function acquires characteristic signals of a test strip (2) detection belt (6) and a quality control belt (7) and calculates the sample single component or multicomponent concentration in combination with the tested object standard curve or coefficient parameters simultaneously red from the storage medium (14) by the instrument. The test strip card for detecting samples has is simple and quick, and has the characteristics of high sensitivity, objective result, high use flexibility and the like.

Description

technical field [0001] The present invention belongs to the field of in vitro diagnosis, and specifically relates to an instrument with a storage medium 14 for storing the detection information such as standard curves or coefficient parameters of the tested object, combined 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 to judge the res...
