Description

Technical Field

[0001] The utility model is applicable to the field of medical testing tools and provides a colorimetric card for medical testing. Background Art

[0002] Point-of-care testing (POCT) usually uses test strips or test plates, which react with biological samples and display the test results. In the analysis of some biological samples, the sample needs to be lysed first, and then the processed sample is dripped onto the test strip or test plate for testing. After the test is completed, colored lines will appear in the result display area, and a color gradient colorimetric card is used to compare with these lines to obtain the final test results.

[0003] Normally, test strips are used in conjunction with colorimetric cards or colorimetric plates. The color of the test strips can be compared with the color descriptions on the colorimetric cards or colorimetric plates, allowing experimenters to more quickly distinguish the results of the experiment. In the case of non-experimental personnel using the test strips, the combination of colorimetric cards or colorimetric plates with the test strips can also allow inexperienced ordinary personnel to accurately identify the test results.

[0004] However, the applicant has found that the existing colorimetric card has the following inconveniences: the installation of the test paper and the colorimetric card is relatively troublesome, and the test paper needs to be installed by inserting it into the groove of the colorimetric card. Since the test paper has a certain degree of softness and is rectangular, unskilled experimenters often insert it improperly, causing the test paper to bend. In the case of large-scale use, the process of installing the test paper is time-consuming and laborious. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a colorimetric card for medical testing, in order to solve the problems raised in the background technology. The device includes a base plate and a cover plate connected by a bending portion, and the cover plate can be covered on the top of the base plate by bending the bending portion. A cavity is formed between the base plate and the cover plate, and a cardboard is installed in the cavity; a first limiting grid is provided on the top of the base plate, and a test paper is installed inside the first limiting grid.

[0006] Furthermore, a second limiting grid is fixedly connected to one side of the cover plate close to the base plate, and the second limiting grid can be embedded in the first limiting grid when the cover plate is closed.

[0007] Furthermore, the second limiting grid abuts against the test paper when embedded in the first limiting grid.

[0008] Furthermore, the test paper is provided with a numbering portion, a colorimetric portion, an explanation portion and a hollow portion, and the first limiting grid is arranged inside the hollow portion.

[0009] Furthermore, the color comparison part is composed of lines of different shades of color arranged sequentially from top to bottom.

[0010] Furthermore, the substrate, cover plate and bending portion are all made of transparent plastic material.

[0011] Furthermore, the base plate, the cover plate and the bending portion are connected as one piece.

[0012] Furthermore, the base plate is provided with an inner recess, the first limiting grid is arranged inside the inner recess, and the cover plate is provided with a snap-fit ​​grid at one end close to the base plate, and the snap-fit ​​grid can be nested inside the inner recess.

[0013] Furthermore, a second reserved hole is provided on the cover plate, and the position of the second reserved hole matches the position of the numbering portion of the paperboard.

[0014] The colorimetric card of the utility model has a pre-installed cardboard inside, on which the information such as the use method, detection method, and colorimetric method of the test paper is written; the experimenter can accurately install the test paper into the colorimetric card by lifting the cover plate, and can easily close the cover plate to fix the test paper. After the test paper is fixed, the experimenter can still use the test paper for experimental color development through the first reserved hole. And the second limit grid can be embedded in the first limit grid and abut against the test paper; it can ensure that the test paper will not shake inside the first limit grid, making the fixation of the test paper more secure. This solves the problem that the installation of the test paper and the colorimetric card is more troublesome, and the test paper will not be bent due to improper insertion. In the case of large-scale use, the process of installing the test paper saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Preferably, the cardboard 5 is made of paper material and is used as a product description of the test paper 5. The cardboard 4 is provided with a numbering portion 41, a colorimetric portion 42, an explanation portion 43 and a hollow portion 44; the numbering portion 41 is used to record the data number of the colorimetric card, and the experimenter can record the experimental number for classification and sorting. The colorimetric portion 42 is arranged on one side of the hollow portion 44, and the colorimetric portion 42 is a line with different shades of color, and the lines are arranged in sequence from top to bottom, which is used to compare the color development on the test paper 5. The explanation portion 43 is arranged in the blank space on the top surface of the cardboard 4, which is used to explain the usage, color development instructions and precautions of the test paper 5. The hollow portion 44 is arranged in the middle of the cardboard 5 and corresponds to the position of the first limit grid 12; the size of the hollow portion 44 is consistent with the size of the outer edge of the first limit grid 12, and the first limit grid 12 can be embedded in the hollow portion 44.

[0026] Specifically, the base plate 1, the cover plate 2 and the bending portion 3 are all made of transparent materials. The base plate 1, the cover plate 2 and the bending portion 3 are made of transparent plastic materials with a certain degree of softness. The base plate 1, the cover plate 2 and the bending portion 3 are integrally connected, and the middle of the bending portion 3 can be bent, so as to realize the flip-opening and closing form of the cover plate 2 on the base plate 1.
