TECHNICAL FIELD
[0001] The utility model relates to the field of microbiological detection equipment consumables, and specifically relates to a solid-liquid two-in-one ATP fluorescence detection swab. BACKGROUND
[0002] The ATP fluorescence detection swab is a tool for rapidly determining the ATP (adenosine triphosphate) content in a sample. The swab usually contains a chemical substance that can react with ATP and produce fluorescence. Once the swab comes into contact with the sample, the chemical substance on the swab reacts with the ATP in the sample, thereby realizing quantitative analysis of the ATP content in the sample. The ATP fluorescence detection swab is widely used in many fields such as food hygiene, medical care and environmental monitoring, and is used for cleanliness detection and rapid screening of microbial contamination.
[0003] There are many types of ATP fluorescence detection swab products on the market, but most of them are single-form swab structures that can only be used for detection of solid or liquid samples. This limitation is particularly evident in actual application. For example, in the case of needing to detect both solid and liquid samples, the user has to carry and use two different swabs, which not only makes the operation complex, but also increases the cost of detection and operation. In addition, the existing ATP fluorescence detection swab has deficiencies in structural strength and sealing, which makes it easy to be contaminated by dust and other pollutants during transportation, storage and carrying. At the same time, the reagent in the kit may be damaged by external force, thereby contaminating the reaction tube and the cotton ball, which may reduce the accuracy of the detection result.
[0004] Therefore, it is of significant practical value to develop a solid-liquid two-in-one ATP fluorescence detection swab that is simple in structure, convenient to operate and can effectively prevent contamination. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.
[0027] Referring to Figures 1 to 3 A preferred embodiment of the solid-liquid two-in-one ATP fluorescence detection swab of the utility model is used for food hygiene detection to ensure the cleanliness of food during production, processing and storage. The detection swab can replace different samplers at the position of the combined assembly part 9 to achieve the purpose of being used for solid sample detection and liquid sample detection.
[0028] In the embodiment, the solid-liquid two-in-one ATP fluorescence detection swab includes multiple structural components independently formed, specifically as shown in the drawings Figure 1 As shown, it includes a push rod body 1, a reagent box 6, a swab support 7, a hollow tube cotton swab, a hollow tube suction head 11, and a reaction tube 12. The aforementioned structural components are independently packaged by small plastic bags matching in size when packaged, and then are secondarily packaged by a large plastic bag. The secondary packaging structure can effectively prevent the components from being contaminated during storage and transportation. Before use, the user only needs to open the outer plastic bag, take out the independently packaged components, and then assemble and assemble according to the needs.
[0029] The push rod body 1 is a cylindrical plastic structural component, the top surface of which is formed with a pressing part, a sealing ring groove is formed at the middle position, and a sealing ring 3 is embedded at the position of the sealing ring groove. The bottom of the push rod body 1 is formed with a sharp head as an unsealing structure 4.
[0030] The swab support 7 is a hollow tube column structure, and the hollow part penetrates up and down. The upper part matches the size of the push rod body 1, so that the push rod body 1 can be inserted and assembled on the swab support 7 for piston sealing assembly. The swab support 7 and the push rod body 1 can form a piston body structure after assembly, and the sealing ring 3 is used for auxiliary sealing in the piston body structure. The swab support 7 is formed with a reagent box support 8 at the lower part of the tube cavity structure, and the reagent box 6 is fixed at the lower part of the tube body of the swab support 7 through the reagent box support 8. The upper and lower surfaces of the reagent box 6 are respectively closed by plastic sealing membranes 5.
[0031] The lower end of the swab support 7 is formed with a combined assembly part 9, which is a combined step surface structure with an inner step, a middle step and an outer step. The swab support 7 can be combined and assembled with the sampling part through the combined step surface structure.
[0032] The corresponding sampling part includes a hollow tube cotton swab, a hollow tube suction head 11 and a reaction tube 12. The hollow tube cotton swab and the hollow tube suction head 11 are alternatively assembled structures, specifically:
[0033] The hollow tube cotton swab includes a transparent plastic tube 10 and a swab head 13 formed at the lower end of the transparent plastic tube 10. The transparent plastic tube 10 ensures clear visibility and uncontaminated sample collection during sampling. The swab head 13 is formed of absorbent cotton material, which has good adhesion and moisture absorption performance. The upper end of the hollow tube cotton swab 10 matches the inner step and can be combined and assembled at the position of the inner step.
[0034] The bottom of the reaction tube 12 is closed, and the top matches the outer step and is combined and assembled at the position of the outer step. The reaction tube 12 is also made of transparent material, so that the sample state and reaction condition can be observed directly during detection.
[0035] The outer diameter of the hollow tube suction head 11 matches the middle step, and the combination assembly is performed through the middle step position.
[0036] In the embodiment, the transparent plastic pipe 10, the reaction tube 12, and the hollow tube suction head 11 are assembled by pressure sleeve connection at the combination assembly position 9. In other embodiments, the pressure sleeve connection can be replaced by screw connection.
[0037] In addition, in the embodiment, in order to improve the convenience of the detection swab, an anti-skid holding part is formed at the middle position of the pipe body of the swab support 7, which facilitates stable holding of the user during operation, and improves the convenience and accuracy of operation.
[0038] In order to prevent the reagent kit 6 in the detection swab from being mistakenly opened after assembly, a detachable clamp 2 is formed on the rod body 1 corresponding to the upper position of the sealing ring 3 as a disassembly structure. The clamp 2 is a one-time opening clamp structure. When the clamp 2 is not disassembled (as shown in Figure 2 ), the lower surface of the clamp 2 abuts against the top surface of the pipe body of the swab support 7 to limit the structure. At this time, the push rod body 1 cannot be pressed downward. By pulling out the clamp 2 outward, the detection swab can be disassembled. At this time, the clamp 2 is no longer limited, and the push rod body 1 can be pressed downward.
[0039] In actual use, the operator first selects a suitable sampler according to the type of sample to be detected, then assembles the swab support 7 with the push rod body 1, and then assembles the hollow tube cotton swab or the hollow tube suction head 11 according to the detection requirement. The hollow tube cotton swab and the hollow tube suction head 11, as the sampling structure, can be integrally sleeved into the reaction tube 12 when assembled independently (as shown in Figure 2 、 Figure 3 ).
[0040] In the embodiment, the hollow tube cotton swab is used for sampling and detecting solid samples. The design allows the swab head 13 to directly adhere to the surface of the solid sample to obtain ATP for detection. The specific operation method is as follows:
[0041] First, the push rod body 1, the reagent kit 6, the swab support 7, the hollow tube cotton swab, and the reaction tube 12 are taken out from the complete swab assembly and assembled. The assembled structure is shown in Figure 2 .
[0042] Then hold the swab support 7, pull out the reaction tube 12, and expose the swab head 13 of the hollow tube cotton swab. Then use the swab head 13 to smear the area to be tested for surface sampling. After sampling, the reaction tube 12 is sleeved.
[0043] At this time, in the case of holding the swab holder 7, the clamp 2 is pulled out, and the push rod body 1 is pressed downward with force, so that the push rod body 1 is sequentially punctured by the opening structure 4 during the downward movement, the reaction reagent in the reagent box 6 is leaked out, and then is pushed out by the piston structure of the push rod body 1, flows along the transparent plastic pipe 10, and flows into the cotton swab head and the reaction tube to participate in the reaction;
[0044] During the reaction process, the reaction tube 12 made of transparent material makes the sample state and the reaction process clear and visible, which is convenient for observation and recording.
[0045] In the embodiment, the hollow tube cotton swab and the hollow tube suction head 11 can be used for sampling and detection of liquid. The hollow tube cotton swab is used for adsorptive sampling of a small amount of liquid sample, and the hollow tube suction head 11 is designed to allow a large amount of sample liquid to be directly sucked from a large amount of liquid sample for ATP detection. The specific operation mode is as follows:
[0046] First, the push rod body 1, the reagent box 6, the swab holder 7, the hollow tube cotton swab or the hollow tube suction head 11, and the reaction tube 12 are taken out from the complete swab assembly and assembled. When the hollow tube cotton swab is used as a sampler, the assembled structure is as shown in Figure 2 ; and when the hollow tube suction head 11 is used as a sampler, the assembled structure is as shown in Figure 3 ;
[0047] In the case of holding the swab holder 7, the clamp 2 is pulled out, and the push rod body 1 is pressed downward with force, so that the push rod body 1 is sequentially punctured by the opening structure 4 during the downward movement, the reaction reagent in the reagent box 6 is leaked out, and then is pushed out by the piston structure of the push rod body 1, flows along the transparent plastic pipe 10, and flows into the cotton swab head and the reaction tube to participate in the reaction;
[0048] Then, the reaction tube 12 is pulled out beside the swab holder 7, and the hollow tube cotton swab / hollow tube suction head 11 is exposed;
[0049] The hollow tube cotton swab or the hollow tube suction head 11 is used for sampling of liquid sample. When the hollow tube cotton swab is used as a sampler for sampling, the swab head 13 is used for dipping sampling. When the hollow tube suction head 11 is used as a sampler for sampling, the sampling is performed in a suction mode similar to a syringe.
[0050] After sampling is completed, the reaction tube 12 is sleeved, and the corresponding liquid sample is fully mixed with the reaction reagent in the reaction tube 12 and participates in the reaction;
[0051] During the reaction process, the reaction tube 12 made of transparent material makes the sample state and the reaction process clear and visible, which is convenient for observation and recording.

It should be understood by the skilled in the art that the purposes of these embodiments are only for illustrating the present application and are not intended to limit the protection scope of the present application.
