Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rapid test kit. Background Technology

[0002] Colorimetric assay kits are experimental tools that use color changes to quantitatively or qualitatively analyze target substances and are widely used in the medical field. The principle is that a specific chemical reaction produces color, and the intensity of the color is directly proportional to the concentration of the target substance. Detection is performed using a spectrophotometer or by visual colorimetry.

[0003] Colorimetric assays require a blood sample processing step before the detection step. However, existing colorimetric assay kits cannot integrate these two steps; the processed blood sample must be transferred to the kit before detection. This significantly impacts the testing cycle and usability.

[0004] To address the aforementioned problems, this invention provides a rapid testing kit to solve the technical problem that existing testing kits cannot simultaneously perform blood sample processing and testing. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This invention provides a rapid test kit that can simultaneously process and test blood samples.

[0027] refer to Figure 1 The rapid test kit disclosed in this embodiment of the present invention includes a main body, which is provided with a reagent chamber 1, a blood sample processing chamber 2 and a reaction chamber 3. The blood sample processing chamber 2 and the reaction chamber 3 are separated by a blood filtration membrane 4, which is used to filter out blood cells in the blood. The reagent chamber 1 and the reaction chamber 3 are located on both sides of the blood sample processing chamber 2, so that the reagent in the reagent chamber 1 can be mixed with the blood sample in the blood sample processing chamber 2 before passing through the blood filtration membrane 4 and entering the reaction chamber 3 for reaction.

[0028] The reagent chamber 1 contains a reagent solution, preferably hydrogen peroxide and tetramethylbenzidine chromogenic agent. The blood sample is placed above the blood filtration membrane 4 in the blood sample processing chamber 2. Due to tension, the blood sample cannot pass directly through the blood filtration membrane 4. The reaction chamber 3 contains a reaction enzyme, preferably a hydrogel ball. During use, pressure is applied to the reagent chamber 1, causing the hydrogen peroxide and tetramethylbenzidine in the reagent chamber 1 to enter the blood processing chamber 2 and mix with the blood sample to form a mixture. Simultaneously, under pressure, the mixture is filtered through the blood filtration membrane 4 to remove blood cells. The mixture after removing red blood cells and white blood cells enters the reaction chamber 3 and mixes with the reaction enzyme in the reaction chamber 3, resulting in a chromogenic reaction. When the analyte corresponding to the hydrogel ball is present in the blood, the hydrogel ball releases catalase. When the hydrogen peroxide is decomposed by the catalase, the tetramethylbenzidine becomes oxidized, causing the solution to turn blue, thus completing the chromogenic reaction and achieving rapid detection.

[0029] In this embodiment, the main body of the box is a split, detachable structure, consisting of a reagent tube 5 with a reagent chamber 1, a blood sample tube 6 with a blood sample processing chamber 2, and a reaction tube 7 with a reaction chamber 3. The reagent outlet end of the reagent tube 5 is detachably connected to the liquid inlet end of the blood sample tube 6, and the liquid outlet end of the blood sample tube 6 is detachably connected to the liquid inlet end of the reaction tube 7. By setting up detachable reagent tube 5, blood sample tube 6, and reaction tube 7, portability can be improved, thereby meeting the requirements for rapid testing and improving applicability.

[0030] In this embodiment, a first sealing ring is provided between the reagent tube 5 and the blood sample tube 6 for sealing, and a second sealing ring is provided between the blood sample tube 6 and the reaction tube 7 for sealing. By providing the first and second sealing rings, the sealing effect can be significantly improved, avoiding leakage problems during use.

[0031] In this embodiment, the reagent tube 5 is a flexible reagent tube that can change the volume of the reagent chamber 1 when pressed. By using a flexible reagent tube, the reagent solution can be pumped into the blood sample processing chamber 2 to participate in the mixing of the blood sample by directly squeezing the reagent tube 5 during the detection stage. At the same time, the pressure provided by manually squeezing the reagent tube 5 can also provide power for the blood membrane 4 of the mixed solution filtration, which is convenient and quick to use.

[0032] In this embodiment, a transparent observation window 8 is installed on the side wall of the blood sample tube 6 to observe the filtration progress inside the blood sample processing chamber; the reaction tube 7 is a transparent tube to observe the reaction progress inside the reaction chamber 3; the arrangement of the transparent observation window 8 and the transparent tube makes it convenient for the testing personnel to intuitively observe the progress of each stage.

[0033] In this embodiment, the reagent tube 5 and the blood sample tube 6, as well as the blood sample tube 6 and the reaction tube 7, are connected by a threaded connection. Other fixing methods in the prior art, such as snap-fit ​​fixing, spring clip fixing, or magnetic fixing, can also be used between the reagent tube 5 and the blood sample tube 6, and between the blood sample tube 6 and the reaction tube 7.

[0034] In this embodiment, the reagent tube 5 is equipped with a one-way valve 9 that only allows reagent to flow into the blood sample processing chamber 2. The one-way valve 9 is detachably connected to the reagent tube 5. The one-way valve 9 avoids contamination from the external environment by utilizing its one-way passage characteristic. At the same time, the one-way valve 9 can be removed during the process of dripping reagent into the reagent tube 5, which facilitates the dripping of reagent.

[0035] In this embodiment, a colorimetric card 10 is fixedly installed on the outer wall of the reaction tube 7; this allows the testing personnel to directly compare the color after the color development reaction with the colorimetric card 10 and quickly obtain the color development result.

[0036] In this embodiment, two reagent tubes 5 are provided, one for holding hydrogen peroxide solution and the other for holding colorimetric reagent solution. Both reagent tubes 5 are light-proof tubes. Depending on the usage requirements, multiple reagent tubes 5 can be provided. At the same time, blood sample tubes 6 with a number of connection ports corresponding to the reagent tubes 5 are selected for cooperation, so that different reagents are placed in separate tubes, improving the accuracy of reagent injection volume control. Meanwhile, the reagent tubes 5 are made of opaque material, forming a dark and sealed space, which can improve the preservation time of reagents in reagent chamber 1 and prevent contamination by the external environment.

[0037] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
