Description
Technical Field
[0001] This utility model relates to the field of sample sampling and testing technology, and in particular to an integrated sampling and testing device. Background Technology
[0002] In existing technologies, stool sampling devices typically employ a small container-like storage tank. After sampling, these devices require a series of complex steps, including manual sample dilution by the lab technician, followed by dripping the sample into a reaction chamber and waiting several minutes to observe the results. This process is not only time-consuming, but the extended separation between sampling and testing steps also increases the risk of sample contamination and spoilage, thus affecting the accuracy and reliability of the test results.
[0003] While current in vitro diagnostic testing products using test strip chromatography integrate reagents and test strips, they still present numerous inconveniences in practical operation, such as cumbersome procedures and stringent environmental requirements. These factors negatively impact testing efficiency and user experience. Therefore, designing a more convenient, efficient, and easy-to-use stool sampling and testing device has become an urgent problem to be solved. Utility Model Content

[0051] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0052] like Figure 1As shown, the integrated sampling and testing device provided in this embodiment includes: a bottle cap component 100, a container bottle body 200, a sampling component 300, and a base body 400.
[0053] The container body 200 is equipped with a reaction cylinder 210 and a receiving cylinder 220 arranged side by side. The cap component 100 is also equipped with a test strip located outside the reaction cylinder 210 and the receiving cylinder 220. The inner wall of the reaction cylinder 210 forms a reaction chamber 211 for storing the reaction liquid. The bottom opening of the reaction cylinder 210 is equipped with a sealing film 213. The reaction cylinder 210 and the sealing film 213 separate the test strip and the reaction liquid, preventing the test strip from contacting the reaction liquid and achieving dry and wet separation.
[0054] The base body 400 is located at the bottom of the container bottle 200. The base body 400 and the container bottle 200 can be connected by snap-fit or by welding. The base body 400 has a test cavity 410, and one end of the test strip inside the container bottle 200 extends into the test cavity 410.
[0055] One end of the sampling component 300 is connected to the bottle cap component 100. The sampling component 300 and the bottle cap component 100 can be designed as a single piece or connected by a snap-fit method.
[0056] The cap component 100 is capable of rotating relative to the container body 200 to switch between a first state and a second state. When not being tested, the cap component 100 is in the first state, and the sampling component 300 extends into the container 220. When sampling is required, the cap component 100 is removed from the container body 200, and then rotated to the second state. The sampling component 300 extends into the reaction chamber 211, and the cap component 100 is capable of pressing down relative to the container body 200 to puncture the sealing film 213. The reaction liquid in the reaction chamber 211 enters the test chamber 410 and contacts the test paper.
[0057] It should be noted that, in order to facilitate the observation of the test strip, the container body 200 can be made entirely of transparent material, or only the part of the container body 200 corresponding to the test strip can be made of transparent material.
[0058] In addition, the outer surface of the bottle cap component 100 is provided with anti-slip texture to make it easier for users to twist the bottle cap component 100.
[0059] The integrated sampling and testing device provided in this embodiment separates the reaction liquid and test strip inside the container body 200 using a reaction cylinder 210 and a sealing film 213 at the bottom opening of the reaction cylinder 210, achieving dry and wet separation and preventing leakage. When no sample is being taken, the capping component is in the first state, and the sampling component 300 extends into the receiving cylinder 220. When sampling is required, the capping component 100 is removed from the container body 200, and after the sampling component 300 obtains the sample, the capping component 100 is rotated to the second state. In the second state, the sampling component 300 extends into the reaction chamber 211, allowing the sample to be fully released into the reaction liquid. When testing is required, the bottle cap component 100 is pressed down, and the sampling component 300 punctures the sealing film 213. The reaction liquid in the reaction chamber 211 enters the test chamber 410 and comes into full contact with the test strip. The test strip reacts and runs on the plate for testing. The overall device has a simple structure and is easy to operate. The sample can be diluted and tested immediately after collection, and the sample is not easily contaminated. This alleviates the technical problems of cumbersome operation and easy sample contamination in the traditional fecal sample collection and testing evaluation of existing technologies.
[0060] Based on the above embodiments, such as Figure 2 As shown, in an optional embodiment, the bottle cap component 100 of the integrated sampling and testing device provided in this embodiment is provided with a sealing rod 110; when the bottle cap component 100 is in the first state, the sealing rod 110 extends into the reaction chamber 211; when the bottle cap component 100 is in the second state, the sealing rod 110 extends into the accommodating cylinder 220, and the sealing rod 110 is used to seal the opening of the reaction cylinder 210 or the accommodating cylinder 220 to prevent the reaction liquid from evaporating.
[0061] like Figure 3 , Figure 4 As shown, in an optional embodiment, the outer wall of the container body 200 is provided with a limiting protrusion 230, which is located at the top of the outer wall of the container body 200 and extends outward. The inner wall of the cap component 100 is provided with a first limiting groove 120 and a second limiting groove 130 arranged vertically at intervals, and the first limiting groove 120 is located below the second limiting groove 130. The limiting protrusion 230 can be engaged in the first limiting groove 120 or the second limiting groove 130. When the cap component 100 moves downward relative to the container body 200, the limiting protrusion 230 disengages from the first limiting groove 120 and moves toward the second limiting groove 130. After the sampling component 300 punctures the sealing film 213, the limiting protrusion 230 extends into the second limiting groove 130.
[0062] Specifically, in the first state of the bottle cap component 100, the limiting protrusion 230 extends into the first limiting groove 120, and the bottle cap component 100 is snapped onto the container body 200 by the first limiting groove 120. When the bottle cap component 100 is in the second state and is pressed down, after the sampling component 300 punctures the sealing film 213, the limiting protrusion 230 extends into the second limiting groove 130, and the bottle cap component 100 is snapped onto the container body 200 by the second limiting groove 130.
[0063] In an optional embodiment, the inner side of the reaction cylinder 210 extends inward to form a first guide plate 212; the inner side of the accommodating cylinder 220 extends inward to form a second guide plate 221. The arrangement of the first guide plate 212 and the second guide plate 221 serves a guiding function, which facilitates the introduction of the sealing rod 110 or the sampling component 300 into the reaction cylinder 210 or the accommodating cylinder 220.
[0064] To secure the test strip within the container body 200, such as Figure 5 As shown, in an optional embodiment, the integrated sampling and testing device further includes a test strip holder 500; the test strip holder 500 is disposed in the container bottle body 200, and the test strip holder 500 has an installation groove 510 for the test strip to extend into, and the groove wall of the installation groove 510 is provided with a fixing nail 520, which can fix the test strip, thereby fixing the test strip in the installation groove 510.
[0065] In an optional embodiment, the inner wall of the container body 200 is provided with guide positioning ribs 240. The guide positioning ribs 240 are right-angled and there are two guide positioning ribs 240 arranged opposite each other. The guide positioning ribs 240 serve to guide the installation of the test strip fixing component 500 and install the test strip fixing component 500 between the two guide positioning ribs 240.
[0066] like Figure 6 As shown, in an optional embodiment, a liquid receiving cylinder 420 is provided inside the base body 400. The liquid receiving cylinder 420 is located in the middle of the base body 400. The inner wall of the liquid receiving cylinder 420 forms a liquid receiving cavity 421. When the sampling component 300 punctures the sealing film 213, the reaction liquid in the reaction chamber 211 flows into the liquid receiving cavity 421. A test cavity 410 is formed between the inner wall of the base body 400 and the outer wall of the liquid receiving cylinder 420. The liquid receiving cylinder 420 has a notch so that the test cavity 410 and the liquid receiving cavity 421 can communicate. The reaction liquid in the reaction chamber 211 first flows into the liquid receiving cavity 421 and then flows into the test cavity 410 for plate running test.
[0067] In an optional embodiment, the bottom of the liquid receiving cylinder 420 has an inclined guide surface 422, which is inclined toward the test chamber 410, so that the liquid in the liquid receiving chamber 421 is guided into the test chamber 410, ensuring that the reaction liquid can flow smoothly into the test chamber 410.
[0068] The end of the first guide plate 212 away from the inner wall of the reaction cylinder 210 is connected to a sealing plate 214 arranged in a vertical direction. The sampling component 300 is provided with a sealing groove 310, and a sealing ring 600 is provided in the sealing groove 310. The sealing ring 600 is sealed to the sealing plate 214, thereby sealing the sampling component 300 and the sealing plate 214 and preventing the reaction liquid in the reaction chamber 211 from flowing out from the gap between the sampling component 300 and the sealing plate 214.
[0069] The sampling component 300 is provided with a sampling groove 320 for obtaining samples. The sampling groove 320 is located below the sealing groove 310, ensuring that after the sampling component 300 is inserted into the reaction chamber 211, the sample in the sampling groove 320 can fully contact the test solution in the reaction chamber 211. Furthermore, the bottom end of the sampling component 300 is provided with a cutting blade 330 for piercing the sealing film 213, ensuring that the sampling component 300 can pierce the sealing film 213.
[0070] In summary, the integrated sampling and testing device provided by this utility model separates the test strip from the test solution in the reaction chamber 211 before use by the sealing film 213, achieving dry and wet separation, increasing sealing, preventing the test solution from evaporating and extending the shelf life. To prevent misoperation, a two-step method is used to puncture the sealing film 213: first, rotate the bottle cap component 100, and then push the bottle cap component 100 down to puncture the sealing film 213. The reaction liquid containing the sample flows through the puncture into the receiving chamber, and after being guided by the guide surface 422, it enters the test chamber 410. The liquid in the test chamber 410 reacts with the test strip to form a colored band on the plate for detection.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
