Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, and particularly to a reagent kit convenient for reading. Background Art

[0002] A detection reagent kit is a box for containing chemical reagents such as chemical components to be detected, drug residues, virus types, etc. In order to meet the needs of the biological and medical fields, water quality detection and other fields, a large number of detection reagent kits have emerged.

[0003] The following introduces a reagent kit that needs to be compared with a color comparison card. As Figure 1 shown, usually, an appropriate amount of liquid sample to be detected is placed in the detection test tube 102, and then the detection test tube 102 is placed on the test tube rack 101. The corresponding reagent is dropped into the detection test tube 102 and reacts with the sample to be detected for a period of time. Then, the color comparison card is used to compare with the color of the sample to be detected, and finally, the color development result is analyzed.

[0004] Since the test tube rack 101 only includes two parts, a base and a support part, when analyzing the color development result, it is necessary to visually observe the color comparison card and the color of the sample successively. Due to the certain distance between the color comparison card and the sample, and at the same time, due to the relatively messy background of the test tube rack 101, there will be a problem of incorrect color interpretation, resulting in inaccurate detection conclusions.

[0005] Therefore, how to design a reagent kit that reduces the color interpretation error of the sample to be detected has become a technical problem that needs to be solved urgently by those skilled in the art. Content of the Utility Model

[0006] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a reagent kit convenient for reading, and solve the problem of large color interpretation error of the sample to be detected.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A reagent kit convenient for reading, including a base, on which there are positioning jacks for placing detection test tubes. The top wall of the base is fixedly provided with a back plate extending vertically upward and located behind the detection test tube. A background plate is installed on the back plate. There is an installation groove on the base, and an observation window communicating with the installation groove and aligned with the positioning jack is provided on the front wall of the base. A color comparison plate and a moving component for driving the color comparison plate to move are slidably installed in the installation groove. A color comparison card aligned with the observation window is installed on the color comparison plate.

[0009] Furthermore, a limit seat extending to the base is fixedly provided on the back plate, and a limit hole aligned with the positioning jack is provided on the limit seat. The detection test tube passes through the limit hole and is inserted into the positioning jack.

[0010] Further, the installation groove opens downward and penetrates through the left and right side walls of the base. The moving assembly includes a moving block, a clamping plate mounted on the moving block and extending into the installation groove, a color comparison plate mounted on the clamping plate, and a handle fixed on the moving block and extending out of the base.

[0011] Further, a supporting bracket is fixedly provided on the base and located below the installation groove, and the bottom wall of the moving block is slidably connected to the top wall of the supporting bracket.

[0012] Further, the background plate is made of non-transparent white material.

[0013] Further, a plug-in groove is recessed inwardly on the side wall of the back plate close to the test tube, a socket communicating with the plug-in groove is provided on the top wall of the limit seat, and the background plate is inserted into the plug-in groove through the socket.

[0014] Further, a storage seat extending vertically upward is fixedly provided on the base. A storage cavity is recessed inwardly on one side wall of the storage seat, a reagent bottle for storing reagents is installed in the storage cavity, and scale lines are longitudinally provided on the side wall of the storage seat.

[0015] Further, at least two groups of positioning jacks are provided and arranged along the length direction of the base. A light-shielding partition plate is installed on the top wall of the base between adjacent two positioning jacks, and the light-shielding partition plate extends vertically upward.

[0016] Further, the light-shielding partition plate is made of non-transparent white or black material.

[0017] Further, the color comparison card includes a first color comparison card provided on the color comparison plate and a second color comparison card located above the first color comparison card. Each group of observation windows includes a first observation window and a second observation window. The second observation window is located above the first observation window. The first color comparison card is aligned with the first observation window, and the second color comparison card is aligned with the second observation window.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: By providing a back plate behind the test tube on the base, the present utility model uses the background plate to block the messy environment behind the test tube, solves the problem of the influence of the miscellaneous colors behind the test tube on the color interpretation of the sample, and improves the accuracy of color interpretation;

[0019] The color of the color comparison plate is read through the observation window aligned with the positioning jack. When the moving assembly moves the color comparison plate inside the installation groove, the color inside the observation window and the test tube sample can be visually observed simultaneously, shortening the distance between the color comparison card and the test tube, and reducing the error of color interpretation.

Specific embodiments

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] This embodiment provides a reagent kit that is convenient for reading, mainly used to reduce the interference of the external environment and solve the problem of incorrect color judgment of the sample to be detected.

[0029] Embodiment 1:

[0030] Such as Figure 2 And Figure 4As shown in the figure, it includes a base 1. A vertical backboard 2 is fixedly arranged on the top wall of the base 1. A limit seat 3 extending upward is provided at the top of the backboard 2. The limit seat 3 extends above the base 1. A plurality of downwardly recessed positioning jacks 10 are provided on the base 1. Limit holes 31 aligned with the positioning jacks 10 are provided on the limit seat 3. It further includes a test tube 102 placed through the limit holes 31 and in the corresponding positioning jacks 10. A background board 5 is installed on one side of the backboard 2 close to the test tube 102. An installation groove 15 is provided on the base 1 along the length direction of the base 1. A plurality of observation windows aligned with the positioning jacks 10 are provided on the side wall of the base 1. The observation windows communicate with the installation groove 15. A colorimetric plate 7 sliding along the length direction of the base 1 is provided in the installation groove 15. It further includes a moving component 8 for driving the colorimetric plate 7 to move. A colorimetric card aligned with the observation windows is installed on the colorimetric plate 7.

[0031] It should be noted here that the background board 5 is white.

[0032] Through the above settings, during the detection process, the test tube 102 is inserted through the limit holes 31 into the corresponding positioning jacks 10 to keep the test tube 102 in a vertical state. Then the sample to be detected is placed into the test tube 102, and a reagent is dropped into the test tube 102 using a dropper to make the reagent react with the sample to be detected and develop color. After a period of time, the moving component 8 drives the colorimetric plate 7 to slide inside the installation groove 15. The color on the colorimetric card is observed through the observation window and compared with the color of the test tube 102. When the colors are the same, the movement of the colorimetric plate 7 is stopped.

[0033] Since the observation window is aligned with the test tube 102, the distance between the colorimetric plate 7 and the test tube 102 can be shortened, enabling the eyes to simultaneously observe the colors of the colorimetric plate 7 and the sample to be detected in the test tube 102, facilitating color judgment. Then, the background board 5 on the backboard 2 is used to isolate the miscellaneous colors behind the test tube 102, thereby avoiding the interference of miscellaneous colors on the color judgment of the sample to be detected and improving the accuracy of color judgment.

[0034] To install the background board 5, in this embodiment, as Figure 4 and Figure 5 shown, a recessed insertion slot 21 is provided on one side wall of the backboard 2 close to the test tube 102. An insertion opening 211 communicating with the insertion slot 21 is provided at the top of the backboard 2. Among them, the background board 5 is inserted into the insertion slot 21 through the insertion opening 211, thereby realizing the installation of the background board 5.

[0035] In this embodiment, as Figure 3 and Figure 5As shown, the opening of the installation groove 15 faces downward, and the installation groove 15 penetrates through the left and right side walls of the base 1. A supporting bracket 16 is provided on the base 1 below the installation groove 15. Among them, the color comparison plate 7 is placed into the installation groove 15 through one side port of the installation groove 15, the color comparison plate 7 is fixed on the moving component 8, and then the moving component 8 extends out of the base 1 through the opening at the bottom of the installation groove 15.

[0036] Specifically, in this embodiment, as Figure 5 and Figure 6 shown, the moving component 8 includes a moving block 81 that slides on the supporting bracket 16. A clamping plate 82 that extends into the installation groove 15 and clamps the color comparison plate 7 is slidably provided on the moving block 81. A handle 83 that extends out of the base 1 is also fixedly provided on the moving block 81.

[0037] Through the above settings, after the color comparison plate 7 is clamped on the clamping plate 82, the color comparison plate 7 can be driven to move by using the handle 83. During the movement of the color comparison plate 7, the color corresponding to the observation window will change. When the color seen through the observation window is the same as the color of the sample to be detected, the movement of the color comparison plate 7 can be stopped, and the test result of the sample can be judged.

[0038] In order to facilitate the storage of reagents, in this embodiment, as Figure 2 and Figure 3 shown, the base 1 is also provided with a storage seat 14 that extends vertically upward. A storage cavity 141 that is recessed inward is provided on one side wall of the storage seat 14. A reagent bottle 6 can be placed inside the storage cavity 141, and the storage of reagents is realized by using the reagent bottle 6.

[0039] In order to facilitate the control of the total amount of the sample to be detected and the reagent in the test tube 102, in this embodiment, as Figure 2 and Figure 4 shown, a scale line 142 that is arranged longitudinally is provided on the side wall of the storage seat 14, so as to observe the total amount of the sample and the reagent in the test tube 102.

[0040] Embodiment 2:

[0041] This embodiment is an improvement made on the basis of Embodiment 1.

[0042] In this embodiment, at least two groups of positioning jacks 10 are provided on the base 1. Specifically, three groups of positioning jacks 10 are provided, and a light-shielding partition 4 that extends vertically upward is provided between adjacent two groups of positioning jacks 10. The light-shielding partition 4 is made of non-transparent white or black. The adjacent two test tubes 102 are blocked by using the light-shielding partition 4. At this time, when observing the color of the sample to be detected inside one of the test tubes 102, the color of the adjacent test tube 102 can be avoided from interfering with the color of the sample to be read, and the accuracy of color judgment can be improved.

[0043] When detecting different samples, the addition amounts of the samples and the dropping amounts of the reagents are different. There is also the problem that the same sample needs to face detections at different concentrations, and it is necessary to compare and process samples at different concentrations.

[0044] In this embodiment, three groups of test tubes 102 are provided, as Figure 3 and Figure 4 shown. From left to right, the concentration of the sample in the test tube 102 gradually increases. Among them, the first test tube 102 is a blank sample. The observation window corresponding to each test tube 102 includes a first observation window 11 and a second observation window 12. The first observation window 11 is located below the second observation window 12, as Figure 6 shown. On the colorimetric plate 7, there is a first color comparison card 71 and a second color comparison card 72 located above the first color comparison card 71. Among them, the first color comparison card 71 is aligned with the first observation window 11, and the second color comparison card 72 is aligned with the second observation window 12.

[0045] Through the above settings, the color of the sample in the rightmost test tube 102 can be read by using the second color comparison card 72 and the second observation window 12, and the color of the sample in the test tube 102 at the middle position can be read by using the first color comparison card 71 and the first observation window 11.

[0046] In order to be able to distinguish the differences in the concentrations of the samples in the three test tubes 102, in this embodiment, as Figure 4 shown, on the side wall of the base 1, there is a concentration mark 13 located on one side of the observation window. Here, the concentration mark 13 can be distinguished by the number of water droplet-shaped grooves.

[0047] Among them, an indication line 41 can also be provided on the side wall of the light-shielding partition 4 to remind of the addition quantity of the sample in the test tube 102.

[0048] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
