Description

Technical Field

[0001] The utility model relates to the field of consumables for microbial detection equipment, and in particular to an ATP fluorescence detection swab with better operating convenience. Background Art

[0002] The ATP fluorescence detection swab is a tool used to rapidly detect the ATP (adenosine triphosphate) content in a sample. The swab typically contains a chemical that reacts with ATP and produces fluorescence. Upon contact with the sample, the chemical on the swab reacts with the ATP in the sample, allowing for quantitative analysis of the ATP content in the sample and assessing cleanliness or microbial contamination levels. ATP fluorescence detection swabs are widely used in fields such as food hygiene, healthcare, and environmental monitoring for cleanliness testing and rapid screening for microbial contamination.

[0003] There are a wide variety of ATP fluorescence detection swab products on the market, including test kits and sampling components. During transportation, storage, and carrying, these products are susceptible to contaminants such as dust, which not only contaminates the reaction tubes and cotton balls but can also reduce the accuracy of test results. The reagents in the test kits can also be damaged by external forces. In addition, the structural design of ATP fluorescence detection swabs is often complex, and the operation process is cumbersome, which not only prolongs the time required for testing but also has a negative impact on detection efficiency. In actual use, the test kits of some swabs may fall off due to shaking.

[0004] Therefore, developing an ATP fluorescence detection swab with a simple structure, convenient operation and effective anti-contamination function has significant practical application value. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0025] See also Figures 1 to 3 A preferred embodiment of an ATP fluorescence detection swab is provided. In this embodiment, the ATP fluorescence detection swab is used for food hygiene detection to ensure the cleanliness of food during production, processing and storage.

[0026] The detection swab includes a bracket body 2 and a reagent kit 1. The bracket body 2 adopts a tubular structure as a whole, the lower part of which is a sampling part 3, the upper part is a reagent kit assembly part, and the reagent kit 1 is assembled through the reagent kit assembly part. In addition, the bracket body 2 is formed with a connecting pipe section connecting the sampling part 3 and the reagent kit assembly part in the middle position inside the tubular structure. The bracket body 2 is formed with multiple annular protrusions on the outer tube surface of the tubular structure as a gripping part 9, which is convenient for the user to hold the swab stably during use.

[0027] The sampling part 3 comprises a hollow tube body 19, the lumen of which is connected with the connecting tube segment 17 at the top, while the bottom of the hollow tube body 19 is shaped with a sample-picking cotton ball 21. The sampling part of the support body 2 comprises a pressure-embedding groove 18 with an inwardly-retracted neck inclined surface, through which the support body 2 is connected with the top of the hollow tube body 19, and after the connection, the lumen of the hollow tube body 19 is kept in communication with the connecting tube segment 17; while the sample-picking cotton ball 21 is used to contact the surface to be detected and to absorb ATP in the sample.

[0028] In order to ensure the accuracy of the detection, in the present embodiment, the detection swab is further shaped with a transparent reaction tube 10 as an outer sleeve at the position corresponding to the sampling part of the sampling part 3. The transparent reaction tube 10 is of a one-time opening structure, and its opening mode is similar to the screw cap design of a beverage bottle. Before use, the user only needs to rotate the upper end part of the transparent reaction tube 10 to easily open it, and after opening, it can be fitted on the outside of the sampling connecting tube segment 17 and the sample-picking cotton ball 21 through a pressure sleeve structure or a threaded screw joint structure or the like. The use of the transparent reaction tube 10 can provide a reaction space for the sample-picking cotton ball 21 in a structure similar to that of a test tube, and the transparent material property can enable the user to directly observe the reaction of the sample and the reagent in the transparent reaction tube 10, so as to quickly judge the ATP content in the sample and improve the detection efficiency.

[0029] The reagent kit assembly part of the detection swab upper part comprises a top-open tubular cavity 15, and the reagent kit 1 lower part has a tubular insertion part 12 matched with the tubular cavity 15. Through the matching of the tubular insertion part 12 and the tubular cavity 15, the reagent kit 1 is formed in the tubular cavity 15 of the support body 2 reagent kit assembly part in an insertion manner and is kept position-fixed.

[0030] The reagent kit 1 has a tubular cavity for containing the medicament as a reagent kit cavity 13 inside the tubular insertion part 12, the bottom surface of which is open and corresponds to the connecting tube segment 17, while the reagent kit 1 uses a plastic sealing film 14 to structurally seal the open surface. The destruction of the plastic sealing film 14 is realized through a film-breaking structure 16, which is a three-blade annular tooth structure in the present embodiment, located at the bottom of the tubular cavity 15 of the support body 2 and directly opposite the lower end of the tubular insertion part 12 of the reagent kit 1. When a positive pressure is applied on the pressing force plane 5 on the top surface of the reagent kit 1, the corresponding pressure will be transmitted to the film-breaking structure 16 through the torsion part 4, so that the three-blade annular tooth structure pierces the plastic sealing film 14, thereby realizing the release of the medicament inside the reagent kit 1.

[0031] In order to ensure the accuracy of the membrane breaking operation and prevent the plastic sealing film of the reagent box cavity 13 from being unsealed due to misoperation, this embodiment is also provided with a combined guide structure, which includes a right-angle guide groove 6 formed on the outer tube wall of the bracket body 2 and a guide structure 11 formed on the reagent box 1, wherein the right-angle guide groove 6 includes a horizontal groove section arranged in a ring and a vertical groove section arranged vertically, and the guide structure 11 is formed on the inner side of the end section of the side connecting arm 8 on the reagent box 1, matching the groove shape of the right-angle guide groove 6, and is embedded in the right-angle guide groove 6; the end section of the side connecting arm 8 is also formed with a pressure hook 7, and the right-angle guide groove 6 is formed with a hook groove matching the pressure hook 7 at the end section of the vertical groove section.

[0032] When the present embodiment is in use, the guide structure 11 can be rotated and translated in the horizontal groove section of the right-angle guide groove 6 by rotating the reagent box 1. When it moves to the vertical groove section position of the right-angle guide groove 6, a pressing force can be applied to the pressure application plane 5 on the top surface of the reagent box 1 to make the pressure hook 7 on the side connecting arm 8 rotate and translate as shown in FIG. Figure 1 、 Figure 2 The shown style is inserted into the groove, and the plastic film 14 is destroyed by the film-breaking structure 16, so that the reagent in the reagent box cavity 13 flows out through the connecting tube section 17 and the hollow tube body 19, and completely infiltrates the sample-picking cotton ball 21. When the outer sleeve 20 is installed, the corresponding reagent is retained in the tube of the outer sleeve 20, and continuously reacts with the sample on the sample-picking cotton ball 21, and a fluorescent color development reaction occurs.

[0033] In order to ensure the smooth rotation of the reagent kit 1, the upper part of the reagent kit 1 is provided with a twisting part 4. The user can amplify the torque through the twisting part 4, and then apply pressure to the membrane breaking structure 16 by pressing the force-applying plane 5 to destroy the plastic sealing film 14, thereby simplifying the operation process and easily completing the membrane breaking operation without worrying about drug leakage or contamination caused by improper operation.

[0034] In this embodiment, the bracket body 2 and the reagent box 1 are designed to be an integrated structure and are plastic-sealed as a whole. This integrated packaging method not only ensures the sealing of the reagent box 1 during transportation and storage, but also effectively avoids the intrusion of pollutants such as dust. In order to prevent misoperation, in this embodiment, the reagent box 1 is pre-assembled in the tubular cavity 15 of the bracket body, and a ring sleeve with a limiting buckle is provided at the connection part between the bracket body 2 and the reagent box 1. The ring sleeve is a disposable unsealing structure and has a limiting protrusion on the inner side. When the ring sleeve is not removed, the limiting protrusion can be used to limit the circumferential movement of the side connecting arm 8 in the horizontal plane, preventing the pressure hook 7 from entering the vertical groove section position of the right-angle guide groove 6. When the ring sleeve is removed, the above-mentioned rotation of the reagent box 1 and the top surface pressing action are performed.

[0035] In another embodiment, the holder 2 and reagent kit 1 can be separate structures, individually sealed in a plastic-sealed package, and then packaged in boxes or bags for secondary packaging. A swab set includes a holder 2 and one or more matching reagent kits 1 pre-assembled with reagents. The advantage of secondary packaging is greater ease of operation, portability, and storage. Separate, independent primary sealed packaging also allows users to combine them according to their needs.

[0036] In summary, the ATP fluorescence detection swab of the utility model simplifies the operation process and improves the accuracy and convenience of detection by optimizing the structural design, while ensuring the hygiene and safety of the product, and has significant practical application value.
