Description

Technical Field

[0001] This utility model relates to the field of sample sampling reaction detection technology, and in particular to an integrated sampling reaction detection device. Background Art

[0002] With the deepening of medical and biological research, the demand for fecal sample collection and analysis is increasing. Traditional fecal sample collection and evaluation systems rely on discrete, tiny, box-like containers for sample collection. These containers are typically designed for short-term sample preservation so that samples can be quickly transferred to a laboratory environment. Inside the laboratory, technicians need to manually perform a series of steps to dilute the sample and transfer it to a specific reactor for further analysis. The specific process includes: initial sample collection, transfer to the laboratory, manual dilution, sample transfer to the reactor, and subsequent testing and analysis.

[0003] While this traditional method meets basic research and clinical needs to some extent, it has significant shortcomings. First, the entire process is time-consuming, requiring multiple steps from sample collection to final result acquisition, each demanding manual intervention, resulting in overall inefficiency. Second, the multiple manual operations increase the risk of sample contamination, potentially leading to biased results. Furthermore, samples must be processed within a specific timeframe; otherwise, their biological activity may decrease, affecting the validity and reliability of the final test results.

[0004] Given the aforementioned issues, the industry urgently needs an integrated solution to improve the efficiency and accuracy of sample processing. The ideal device should enable integrated operation from sample collection to test result analysis. Such an innovative device would not only simplify procedures and shorten testing time but also significantly improve the accuracy and repeatability of sample processing, thereby overcoming many limitations of existing systems and greatly enhancing laboratory efficiency and the quality of sample management.

The capping component can be switched between a first and a second position by rotating it. In the first position, the sampling component is located in the reaction chamber, allowing the sample to fully react. At this position, the capping component cannot move downwards relative to the container component. When the capping component rotates to the second position, it can move downwards relative to the container component, causing the sampling component connected to the capping component to pierce the sealing film. The test solution in the reaction chamber enters the test chamber and fully contacts the test strip, which then reacts and performs detection. The overall device has a simple structure and is easy to operate. Reaction and detection can be performed immediately after sample collection, and the sample is less prone to contamination and compositional changes.

[0059] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0062] 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.

[0063] like Figure 1 As shown, the integrated sampling reaction detection device provided in this embodiment includes: a capping component 100, a container component 200, a base body 300, and a sampling component 400; a reaction cylinder 210 and a test strip 220 are disposed inside the container component 200, the test strip 220 is located outside the reaction cylinder 210, the inner wall of the reaction cylinder 210 is surrounded to form a reaction chamber 211 for storing the test solution, and a sealing film 212 is provided at the bottom opening of the reaction cylinder 210, the sealing film 212 can prevent the reaction cylinder 210 and the sealing film 212 from separating the test strip 220 and the test solution.

[0064] One end of the sampling component 400 is connected to the capping component 100. The sampling component 400 is used to obtain a sample. After obtaining the sample, the sampling component 400 extends into the reaction chamber 211 to fully mix and react with the sample.

[0065] The base body 300 is located at the bottom of the container component 200. The connection between the base body 300 and the container component 200 can be in various ways. A buckle can be set at the bottom of the container component 200, and a slot can be set at the top of the base body 300. The buckle and the slot cooperate to achieve the connection between the base body 300 and the container component 200. Alternatively, the base body 300 can be welded to the container component 200.

[0066] The base body 300 has a test chamber 310. One end of the test paper 220 in the container component 200 extends into the test chamber 310. After the sampling component 400 punctures the sealing film 212, the test solution in the reaction chamber 211 flows into the test chamber 310 and comes into contact with the test paper 220 for plate running test.

[0067] The capping member 100 is capable of rotating relative to the container member 200 to switch between a first position and a second position.

[0068] When the capping member 100 is in the first position, the sampling member 400 extends into the reaction chamber 211 so that the sample reacts in the reaction chamber 211. At this time, the capping member 100 cannot press down relative to the container member 200, so the sampling member 400 cannot puncture the sealing film 212.

[0069] When the capping member 100 is in the second position, the sampling member 400 can be pressed down relative to the container member 200 so that the sampling member 400 punctures the sealing film 212, and the test solution in the reaction chamber 211 enters the test chamber 310 and comes into contact with the test paper 220.

[0070] It should be noted that the container component 200 can be made of transparent material to facilitate observation of the test paper 220.

[0071] The integrated sampling, reaction, and detection device provided in this embodiment separates the test solution and test paper 220 within the container component 200 by setting a reaction cylinder 210 inside the container component 200 and using the reaction cylinder 210 and the sealing film 212 at the bottom opening of the reaction cylinder 210 to achieve dry and wet separation, preventing leakage. Furthermore, by screwing on the capping component 100, the capping component 100 can be switched between a first position and a second position. When the capping component 100 is in the first position, the sampling component 400 is located in the reaction chamber 211, and the sample reacts fully. At this time, the capping component... The capping component 100 cannot be pressed down relative to the container component 200. When the capping component 100 is rotated to the second position, the capping component 100 can be pressed down relative to the container component 200, thereby driving the sampling component 400 connected to the capping component 100 to pierce the sealing film 212. The test solution in the reaction chamber 211 enters the test chamber 310 and fully contacts the test strip 220. The test strip 220 reacts and runs to perform the test. The overall device has a simple structure and is easy to operate. The reaction test can be performed immediately after the sample is collected. The sample is not easily contaminated or its composition changes.

[0072] Based on the above embodiments, in optional implementations, such as Figure 3 , Figure 4 As shown, in the integrated sampling reaction detection device provided in this embodiment, a slider 230 is slidably provided on the top end face of the container component 200. The slider 230 can slide on the top end face of the container component 200. A blocking protrusion 110 is provided on the end face of the capping component 100. When the capping component 100 is in the first position, the bottom surface of the blocking protrusion 110 abuts against the top surface of the slider 230, thereby preventing the capping component 100 from pressing down and moving relative to the container component 200, and the sampling component 400 cannot pierce the sealing film 212.

[0073] like Figure 2As shown, in an optional embodiment, the end face of the capping member 100 is provided with an abutment protrusion 120, the bottom of the abutment protrusion 120 has a slope 121, and the outer side of the slider 230 has a slope 231. When the capping member 100 is in the second position, when the capping member 100 is pressed down and moved, the slope 121 and the slope 231 abut against each other, the abutment protrusion 120 pushes the slider 230 to move towards the reaction cylinder, and the sampling member 400 is pressed down and moved together with the capping member 100, so that the sampling member 400 punctures the sealing film 212.

[0074] like Figure 4 As shown, in an optional embodiment, the top end face of the container component 200 is provided with a guide protrusion 240, and the slider 230 has a through hole 232. The guide protrusion 240 passes through the through hole 232 so that the guide protrusion 240 restricts the sliding direction of the slider 230, thereby allowing the slider 230 to move only along the guide protrusion 240.

[0075] like Figure 5 As shown, the side wall of the guide protrusion 240 is provided with a snap-fit ​​protrusion 241, and the inner wall of the through hole 232 is provided with a snap-fit ​​groove 233. The snap-fit ​​protrusion 241 can extend into the snap-fit ​​groove 233 so that the slider 230 has a sliding resistance force.

[0076] Specifically, when no test is performed, the snap-fit ​​protrusion 241 extends into the snap-fit ​​groove 233, snapping the slider 230 onto the guide protrusion 240 and fixing the position of the slider 230. When the capping component 100 is in the second position, pressing down on the capping component 100 causes the inclined surface 121 to abut against the inclined plate 231. The downward movement overcomes the sliding force, causing the abutment protrusion 120 to push the slider 230 along the guide protrusion 240, thus disengaging the snap-fit ​​protrusion 241 from the snap-fit ​​groove 233. The sliding resistance setting can prevent misoperation. Only when the user applies force to press down on the capping component 100 can the sealing film 212 be punctured.

[0077] It should be noted that the guide protrusion 240 and the snap-fit ​​protrusion 241 are made of flexible material to ensure that the snap-fit ​​protrusion 241 can be dislodged from the snap-fit ​​groove 233.

[0078] In an optional embodiment, a connecting cylinder 130 is provided in the middle of the capping component 100, one end of the sampling component 400 extends into the connecting cylinder 130, and the sampling component 400 is connected to the connecting cylinder 130. The connection method between the sampling component 400 and the connecting cylinder 130 can be a snap-fit ​​connection or an integral connection. The specific connection method between the sampling component 400 and the connecting cylinder 130 can be selected according to the actual situation.

[0079] like Figure 2 As shown, a stop rib 131 protrudes from the outer wall of the connecting cylinder 130; as Figure 4As shown, the inner wall of the reaction cylinder 210 is provided with a first stop groove 213 and a second stop groove 214 at intervals along the inner circumference. When the capping member 100 is in the first position, the stop rib 131 extends into the first stop groove 213. When the capping member 100 is in the second position, the stop rib 131 extends into the second stop groove 214. The first stop groove 213 and the second stop groove 214 are set at 90 degrees. When not being tested, the stop rib 131 extends into the first stop groove 213. The blocking protrusion 110 is located above the slider 230. The downward movement of the capping member 100 will be blocked by the slider 230 and the blocking protrusion 110. Therefore, the capping member 100 cannot be pressed down. When testing is required, rotate 90 degrees clockwise to make the stop rib 131 rotate to the position where it extends into the second stop groove 214. Press the capping member 100 to move downward and cut the sealing film 212 through the sampling member 400.

[0080] In an optional embodiment, the outer wall of the connecting cylinder 130 is provided with an upper limit rib 132 along the outer circumference; the inner wall of the reaction cylinder 210 is provided with a lower limit rib 215 along the inner circumference. When the capping component 100 is pressed down, the upper limit rib 132 and the lower limit rib 215 can abut against each other to form a downward pressure resistance force. The setting of the downward pressure resistance force can play a role in preventing misoperation. Only when the user applies force to press down on the capping component 100, and the upper limit rib 132 passes over the lower limit rib 215, can the sealing film 212 be punctured.

[0081] It should be noted that the stop rib 131, the upper limit rib 132, and the lower limit rib 215 are all made of flexible materials.

[0082] In order to fix the test strip 220 in the container component 200, such as Figure 6 As shown, the sample collection and testing device also includes a test strip mounting component 500; the test strip mounting component 500 is disposed within the container component 200.

[0083] Specifically, the test strip mounting component 500 has a mounting groove 510 for the test strip 220 to extend into, and the groove wall of the mounting groove 510 is provided with mounting pins 520, which can fix the test strip 220.

[0084] like Figure 7 As shown, in order to fix the test strip mounting component 500 in the container component 200, an mounting plate 250 is formed on the inner wall of the container component 200, and a fixing groove 251 is provided on the side of the mounting plate 250; a fixing protrusion 530 is provided on the outer wall of the test strip mounting component 500, and the fixing protrusion 530 extends into the fixing groove 251, thereby fixing the test strip mounting component 500 on the mounting plate 250, and thus fixing the test strip 220 in the container component 200.

[0085] It should be noted that there are two mounting plates 250, which are arranged opposite each other, and the fixing component is sandwiched between the two mounting plates 250.

[0086] like Figure 8 As shown, in an optional embodiment, a liquid receiving cylinder 320 is provided inside the base body 300. The liquid receiving cylinder 320 is located in the middle of the base body 300. The inner wall of the liquid receiving cylinder 320 forms a liquid receiving cavity 321. When the sampling component 400 punctures the sealing film 212, the test solution in the reaction chamber 211 flows into the liquid receiving cavity 321. A test cavity 310 is formed between the inner wall of the base body 300 and the outer wall of the liquid receiving cylinder 320. The liquid receiving cylinder 320 has a notch so that the test cavity 310 and the liquid receiving cavity 321 can communicate. The test solution in the reaction chamber 211 first flows into the liquid receiving cavity 321 and then flows into the test cavity 310 through the notch for plate running test.

[0087] In an optional embodiment, the bottom surface of the liquid receiving cylinder 320 has an inclined guide surface 330, which is inclined toward the test chamber 310, so that the liquid in the liquid receiving chamber 321 is guided into the test chamber 310, ensuring that the test solution can flow smoothly into the test chamber 310.

[0088] like Figure 1 As shown, in an optional embodiment, the inner side of the reaction cylinder 210 extends inward to form a connecting plate 216. The connecting plate 216 is inclined toward the direction close to the sealing film 212. The inclined connecting plate 216 can play a guiding role in guiding the sampling component 400 into the reaction chamber 211.

[0089] The end of the connecting plate 216 away from the inner wall of the reaction cylinder 210 is connected to a sealing plate 217 arranged in a vertical direction. The sampling component 400 is provided with a sealing groove 420, and a sealing ring 600 is provided in the sealing groove 420. The sealing ring 600 is sealed to the sealing plate 217, thereby sealing the sampling component 400 and the sealing plate 217 to prevent the test solution in the reaction chamber 211 from flowing out from the gap between the sampling component 400 and the sealing plate 217.

[0090] like Figure 2 As shown, the sampling member 400 is provided with a sampling groove 410 for obtaining samples. The sampling groove 410 is located below the sealing groove 420, ensuring that after the sampling member 400 is inserted into the reaction chamber 211, the sample in the sampling groove 410 can fully contact the test solution in the reaction chamber 211. Furthermore, the bottom end of the sampling member 400 is provided with a cutting blade 430 for piercing the sealing film 212, ensuring that the sampling member 400 can pierce the sealing film 212.

[0091] In summary, the integrated sampling, reaction, and detection device provided by this utility model separates the test strip 220 from the test solution in the reaction chamber 211 before use by a sealing film 212, achieving dry-wet separation, increasing sealing performance, preventing evaporation of the test solution, and extending its shelf life. To prevent misoperation, a two-step method is used to puncture the sealing film 212: first, rotate the capping component 100, then push the capping component 100 down to puncture the sealing film 212. The test solution containing the sample flows through the puncture into the receiving chamber, is guided by the guide surface 330, and then enters the test chamber 310. The liquid in the test chamber 310 reacts with the test strip 220 to form a colored band on the reaction plate, which is then used for detection.

[0092] 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.
