DETAILED DESCRIPTION

[0020] The following is a further embodiment of the utility model in conjunction with the accompanying drawings. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, a portable colorimetric device comprises a card slot 1 and a colorimetric plate 2, wherein the colorimetric plate 2 is rectangular, the card slot 1 is arranged above one end of the colorimetric plate 2 in the width direction, the card slot 1 is a hollow cuboid with one end not sealed, the unsealed end of the card slot 1 is one end in the width direction, the length direction of the card slot 1 is the same as the width direction of the colorimetric plate 2, a colorimetric window 11 is arranged at the front end of the card slot, and the colorimetric window 11 is a hollow structure, through which the corresponding position in the card slot 1 can be observed In the case of the arrangement of the colorimetric window 11 at the front end of the card insertion slot 1, the setting position of the colorimetric window 11 corresponds to the position of the detection area when the reagent card is inserted into the card insertion slot 1, and the detection line can be observed from the colorimetric window. It is necessary to set the colorimetric windows 11 at different positions according to the actual model of the reagent card, so that only the detection line of the reagent card is displayed in the colorimetric window 11 without displaying the quality control line. A reference value color band 12 is provided at the side end of the colorimetric window 11 at the front end of the card insertion slot 1, and the reference value color band 12 can be compared with the detection line of the reagent card for subsequent interpretation.

[0022] The length direction of the reference value color strip 12 is the same as the length direction of the colorimetric plate 2 .

[0023] The colorimetric plate 2 is provided with a plurality of parallel interpretation color bands 21 , the length direction of the interpretation color bands 21 is the same as the length direction of the colorimetric plate 2 , and each interpretation color band 21 has a different color.

[0024] The reference value color band 12 coincides with the extension line of the detection line when the reagent card is inserted into the card slot 1, and the extension line of the reference value color band 12 coincides with one of the interpretation color bands 21. During detection, the position of the detection line visible in the colorimetric window 11 remains flush with the reference value color band on the right, which is more convenient for comparison. At the same time, further analysis can be performed based on the interpretation color band 21 on the colorimetric plate 2.

[0025] An indication area 13 is provided at the front end of the card insertion slot 1, and the indication area 13 includes a sampling point indication position 13a and a direction arrow 13b. The sampling point indication position 13a is located at an unsealed end of the card insertion slot 1 relative to the colorimetric window 11 and is away from the sampling point on the reagent card. The sampling point indication position 13a corresponds to the position of the sampling point on the reagent card.

[0026] The indicator area 13 also includes a diluent point indicator position 13c, which corresponds to the position of the diluent drop point on the reagent card. Since some reagent cards contain both sampling points and diluent drop points, adding a diluent point indicator position 13c to the indicator area 13 can make the indication clearer.

[0027] The colorimetric plate 2 is provided with a result interpretation area 22, and the result interpretation area 22 corresponds to the test result corresponding to different interpretation color bands. In the determination of some quantitative reagent cards, the concentration measured by the test line can be further obtained according to the indication of the result interpretation area 22 and the color band concentration mark.

[0028] like Figure 3 As shown, in order to save space, the colorimetric card that is usually matched with the reagent card is a flat product. When in use, the colorimetric device is folded 90 degrees along the dotted line to fold out the card insertion slot 1, and fixed by the adhesive strip 3, and the reagent card indicating area 13 after the sample addition reaction is completed is inserted into the card insertion slot 1 in the direction indicated by the arrow 13b, so that the sampling point of the reagent card corresponds to the sampling point indicator position 13a. At this time, the detection line of the reagent card is located in the colorimetric window 11.

[0029] In qualitative testing, if the sample being tested is a negative sample or a sample with a concentration lower than the minimum detection limit of the product, no lines will appear in the colorimetric window 11, that is, it is blank; if the sample being tested is a positive sample or a sample with a concentration higher than the minimum detection limit of the product, only one detection line can be observed in the colorimetric window 11.

[0030] In quantitative detection, if the color depth of the detection line in the colorimetric window 11 is consistent with the color of the reference value color band 12 on the right, the concentration value of the indicator is just the reference value; if the color of the detection line in the colorimetric window 11 is lighter than the reference value color band 12 on the right, it means that the measured indicator is lower than the reference value; if the color of the detection line in the colorimetric window 11 is darker than the reference value color band 12 on the right, it means that the measured indicator is higher than the reference value. The specific intensity of the indicator can correspond to the corresponding concentration value range according to the depth of the color band, thereby semi-quantitatively indicating the risk of the detected disease.

[0031] This product is suitable for auxiliary interpretation of qualitative or semi-quantitative test results of visual immunoassay, including but not limited to colloidal gold method, latex method and other detection reagents.

[0032] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
