[0002] With the continuous advancement of medical technology and disease diagnostic methods, stool sample testing has become an indispensable part of clinical diagnosis. Stool sample testing can be used to screen for a variety of diseases, such as intestinal infections, parasitic infections, and certain types of cancer. To facilitate patient sampling and hospital testing, a variety of stool sampling devices have emerged on the market. Among them, the most common is a small, box-like stool collection container, which is simple in design and allows patients to collect samples themselves at home.

[0003] However, existing stool sampling devices have some significant problems in practical use. After sampling, the technician needs to perform a series of complex steps, including manually diluting the sample and then dripping it into the reaction chamber and waiting several minutes to observe the test results. This process is not only time-consuming, but also prone to sample contamination and deterioration due to the long separation time between sampling and testing, thus affecting the accuracy and reliability of the test results.

Detailed Implementation

[0051] 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.

[0052] like Figure 1 As shown, the integrated device with integrated sampling reaction detection function provided in this embodiment includes: a sampling bottle cap 100, a sealing bottle cap 200, a tube body 300, a sampling rod 400, and a base body 500; the tube body 300 is provided with a reaction cylinder 310 and a container cylinder 320, which are arranged in parallel and side by side, and a test strip 330 is provided inside the tube body 300 and located outside the reaction cylinder 310 and the container cylinder 320. The inner wall of the reaction cylinder 310 is surrounded to form a reaction chamber 311 for storing the test solution, and a sealing film 312 is provided at the bottom opening of the reaction cylinder 310. The reaction cylinder 310 and the sealing film 312 separate the test strip 330 and the test solution to achieve the function of dry and wet separation.

[0053] The base body 500 is located at the bottom of the tube body 300. The base body 500 and the tube body 300 can be connected by snap-fit ​​or by welding. The base body 500 has a test cavity 510, and one end of the test paper 330 inside the tube body 300 extends into the test cavity 510.

[0054] One end of the sampling rod 400 is connected to the sampling bottle cap 100. The sampling rod 400 and the sampling bottle cap 100 can be an integral design or connected by a snap-fit ​​method.

[0055] The sampling bottle cap 100 and the sealing bottle cap 200 are configured to slide relative to each other in the vertical direction, thereby enabling the sampling bottle cap 100 and the sealing bottle cap 200 to slide relative to each other in the vertical direction.

[0056] When the integrated device is in the first state, the sampling bottle cap 100 is placed on the container 320, the sampling rod 400 extends into the container 320, and the sealing bottle cap 200 is placed on the reaction cylinder 310.

[0057] When the integrated device is in the second state, the sealing cap 200 is placed on the container 320, the sampling rod 400 extends into the reaction cylinder 310, and the sampling cap 100 can slide relative to the sealing cap 200 to press down, so that the sampling rod 400 pierces the sealing film 312, and the test solution containing the sample in the reaction chamber 311 enters the test chamber 510 and comes into contact with the test paper 330.

[0058] It should be noted that, in order to facilitate observation of the test strip 330, the tube body 300 can be made entirely of transparent material, or only the part of the tube body 300 corresponding to the test strip 330 can be made of transparent material.

[0059] The integrated sampling and reaction detection device provided in this embodiment uses a reaction cylinder 310 inside the tube body 300. The reaction cylinder 310 and a sealing film 312 at its bottom opening separate the test solution and test paper 330 within the tube body 300, achieving dry-wet separation and preventing leakage. When not sampling, the entire device is in its first state, with the sampling bottle cap 100 covering the container 320, the sampling rod 400 extending into the container 320, and the sealing cap 200 covering the reaction cylinder 310. During sampling, the sampling bottle cap 100 is removed from the tube body 300, and the sampling rod 400 extends from the container 320 to take a sample. During reaction detection, the entire device... In the second state, the sealing cap 200 is placed on the container 320, and the sampling cap 100 is placed on the reaction cylinder 310, allowing the sampling rod 400 to extend into the reaction chamber 311. The sampling cap 100 can slide and press down relative to the sealing cap 200. The sampling rod 400 pierces the sealing film 312, and the test solution containing the sample in the reaction chamber 311 enters the test chamber 510 and makes full contact with the test strip 330. The test strip 330 reacts and performs the test. The overall device has a simple structure and is easy to operate. The sample can be diluted and tested immediately after collection. The sample is not easily contaminated or decomposed, which alleviates the technical problems of cumbersome traditional fecal sample collection and testing operations and easy sample contamination and decomposition in the prior art.

[0060] Based on the above embodiments, such as Figure 2 , Figure 3 As shown, in an optional embodiment, the sealing cap 200 of the integrated device for integrated sampling reaction detection provided in this embodiment has a sliding groove 210 on the side near the sampling cap 100. Specifically, the end face of the sealing cap 200 near the sampling cap 100 is a plane, and a downward-facing sliding groove 210 is formed on the plane. A sliding protrusion 110 extends outward from the side of the sampling cap 100 near the sealing cap 200. The sliding protrusion 110 extends into the sliding groove 210 and moves along the sliding groove 210, thereby allowing the sampling cap 100 and the sealing cap 200 to slide relative to each other.

[0061] In an optional embodiment, the wall of the sliding groove 210 extends inward to form a snap-fit ​​protrusion 211; the outer side of the sliding protrusion 110 is provided with a snap-fit ​​groove 111; the snap-fit ​​protrusion 211 can extend into the snap-fit ​​groove 111 so that the sampling bottle cap 100 and the sealing bottle cap 200 snap together, connecting the sampling bottle cap 100 and the sealing bottle cap 200 into a whole.

[0062] In addition, the snap-fit ​​between the sampling cap 100 and the sealing cap 200 creates a downward pressure resistance. After the sampling rod 400 finishes sampling, it extends into the reaction cylinder 310, where the sample and test solution are fully mixed. When testing is required, the user needs to press down on the sampling cap 100. Due to the downward pressure resistance, the user needs to apply a lot of force to move the sampling cap 100. The downward pressure resistance is designed to prevent misoperation; testing can only be performed by the user pressing down with great force.

[0063] like Figure 4 As shown, in an optional embodiment, the tube body 300 has a stepped protrusion 340 protruding upward from the outer edge of the accommodating cylinder 320, and a guide rib 350 protruding upward from the top surface of the stepped protrusion 340; both the bottom end face of the sampling bottle cap 100 and the sealing bottle cap 200 are provided with stepped grooves 120, and the guide rib 350 can extend into the stepped groove 120. The guide rib 350 and the stepped groove 120 cooperate to facilitate the positioning of the sampling bottle cap 100 or the sealing bottle cap 200 on the stepped protrusion 340.

[0064] It should be noted that the overall height of the sampling bottle cap 100 is smaller than that of the sealing bottle cap 200. In the first state, the sampling bottle cap 100 is installed on the stepped protrusion 340, and the sampling bottle cap 100 is at the same height as the sealing bottle cap 200 above the reaction cylinder 310. In the second state, because the overall height of the sampling bottle cap 100 is smaller, after the sealing bottle cap 200 is installed on the stepped protrusion 340, the sampling bottle cap 100 still has a distance from the top surface of the reaction cylinder 310, thus giving the sampling bottle cap 100 downward movement space to pierce the sealing film 312.

[0065] In an optional embodiment, the sealing cap 200 is provided with a sealing rod 220; when the integrated device is in the first state, the sealing rod 220 extends into the reaction cylinder 310, and the sealing rod 220 serves to seal the reaction cylinder 310, preventing the test solution in the reaction cylinder 310 from being exposed for a long time under normal conditions; when the integrated device is in the second state, the sealing rod 220 extends into the receiving cylinder 320, and the sealing rod 220 serves to guide and position, making it convenient for the sealing cap 200 to be installed on the tube body 300.

[0066] In an optional embodiment, the inner side of the reaction cylinder 310 extends inward at an inward angle to form a guide plate 313. The guide plate 313 is perforated and serves to guide the sampling rod 400 into the reaction chamber 311. The end of the guide plate 313 away from the inner wall of the reaction cylinder 310 is connected to a vertically arranged sealing plate 314. The sampling rod 400 is provided with a sealing groove 410, and a sealing ring 700 is provided in the sealing groove 410. The sealing ring 700 is sealed to the sealing plate 314, thereby sealing the sampling rod 400 and the sealing plate 314 to prevent the test solution in the reaction chamber 311 from flowing out from the gap between the sampling rod 400 and the sealing plate 314.

[0067] In order to fix the test strip 330 in the tube body 300, such as Figure 5 As shown, in an optional embodiment, the integrated sampling and testing device further includes a test strip holder 600; the test strip holder 600 is disposed in the tube body 300, and the test strip holder 600 has an installation groove 610 into which the test strip 330 extends. The groove wall of the installation groove 610 is provided with a fixing nail 620, which can fix the test strip 330, thereby fixing the test strip 330 in the installation groove 610.

[0068] like Figure 6 As shown, in an optional embodiment, a liquid receiving cylinder 520 is provided inside the base body 500. The liquid receiving cylinder 520 is located in the middle of the base body 500. The inner wall of the liquid receiving cylinder 520 forms a liquid receiving cavity. When the sampling rod 400 punctures the sealing film 312, the test solution containing the sample in the reaction chamber 311 flows into the liquid receiving cavity. A test cavity 510 is formed between the inner wall of the base body 500 and the outer wall of the liquid receiving cylinder 520. The liquid receiving cylinder 520 has a notch so that the test cavity 510 communicates with the liquid receiving cavity. The test solution containing the sample in the reaction chamber 311 first flows into the liquid receiving cavity and then flows into the test cavity 510 for plate running detection.

[0069] In an optional embodiment, the bottom of the liquid receiving cylinder 520 has an inclined guide surface 530, which is inclined toward the test chamber 510, so that the liquid in the liquid receiving chamber is guided into the test chamber 510, ensuring that the test solution containing the sample can flow smoothly into the test chamber 510.

[0070] The end of the guide plate 313 away from the inner wall of the reaction cylinder 310 is connected to a sealing plate 314 arranged in a vertical direction. The sampling rod 400 is provided with a sealing groove 410, and a sealing ring 700 is provided in the sealing groove 410. The sealing ring 700 is sealed to the sealing plate 314, thereby sealing the sampling rod 400 and the sealing plate 314 to prevent the test solution in the reaction chamber 311 from flowing out from the gap between the sampling rod 400 and the sealing plate 314.

[0071] like Figure 2 As shown, the sampling rod 400 is provided with a sampling groove 420 for obtaining samples. The sampling groove 420 is located below the sealing groove 410, ensuring that after the sampling rod 400 is inserted into the reaction chamber 311, the sample in the sampling groove 420 can fully contact the test solution in the reaction chamber 311. Furthermore, the bottom end of the sampling rod 400 is provided with a cutting blade 430 for piercing the sealing film 312, ensuring that the sampling rod 400 can pierce the sealing film 312.

[0072] 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.
