[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0019] Example: Please refer to Figure 1 - Figure 6This utility model provides a technical solution: a leak-proof urine sampler for nephrology patients, comprising: a support plate 1, which provides stable support during use of the sampler; a flow guiding device 2, the outer wall of which is fixedly connected to the inner wall of the support plate 1, which guides the flow of urine; a leak-proof device 3, the outer wall of which is slidably connected to the inner wall of the flow guiding device 2, which cooperates with the flow guiding device 2 to control the flow direction of urine; a connecting device 4, the outer wall of which is fixedly connected to the outer wall of the flow guiding device 2, which is used to install a sampling tube; and a sampling device 5, the outer wall of which is screwed to the outer wall of the connecting device 4. The sampling device 5 is used to sample urine. The diversion device 2 includes a connecting tube 21, a diversion tube 22 is fixedly connected to the inner wall of the connecting tube 21, a liquid storage box 23 is fixedly connected to the outer wall of the top of the connecting tube 21, a baffle plate 24 is fixedly connected to the inner wall of the liquid storage box 23, and a connecting hole 25 is opened in the wall of the liquid storage box 23. After the urine enters through the opening at the top of the liquid storage box 23, the diversion device 2 starts to work. The urine will first flow into the liquid storage box 23. At this time, the baffle plate 24 in the liquid storage box 23 can play a certain role in buffering and diverting the urine, and the urine is guided by the baffle plate 24 into the connecting tube 21 deep in the liquid storage box 23 to prevent the urine from directly impacting and splashing.
[0020] The leak-proof device 3 includes a connecting rod 31. A rotating ring 32 is fixedly connected to the inner wall of the bottom of the connecting rod 31. A leak-proof column 33 is fixedly connected to the outer wall of the middle part of the connecting rod 31. First sealing rings 34 are symmetrically fixedly connected to both ends of the leak-proof column 33. A blocking column 35 is fixedly connected to the outer wall of the top of the connecting rod 31. Second sealing rings 36 are symmetrically fixedly connected to the outer walls of both ends of the blocking column 35. The side walls of the leak-proof column 33 and the blocking column 35 are slidably connected to the inner side wall of the connecting pipe 21. The outer walls of the first sealing ring 34 and the second sealing ring 36 are slidably connected to the inner side wall of the connecting pipe 21. The outer wall of the connecting pipe 21 is fixedly connected to the inner wall of the support plate 1. In use, the connecting rod 31 drives the connected components to prevent leakage. The column 33, the first sealing ring 34 at both ends, the blocking column 35, and the second sealing ring 36 at both ends slide on the inner side wall of the connecting pipe 21. By adjusting their positions, the flow direction of urine can be controlled. When the blocking column 35 and the second sealing ring 36 are both located above the opening of the guide pipe 22, urine will be prevented from flowing out randomly and will be accumulated in the liquid collection box 23, thus achieving a good leak-proof effect. At this time, the urine level will gradually rise above the top of the fixed ring 41 as it accumulates, allowing the urine to enter the sampling device 5 from the connecting device 4 and complete the sampling process. When the rotating ring 32 is pulled and the connecting rod 31 is pulled down, the blocking column 35 and the second sealing ring 36 will open the opening of the guide pipe 22, and the urine will flow out through the guide pipe 22.
[0021] The connecting device 4 includes a fixing ring 41, a guide bucket 42 is fixedly connected to the outer wall of the bottom of the fixing ring 41, a limit tube 43 is fixedly connected to the outer wall of the guide bucket 42, and an internal thread groove 44 is opened in the wall of the limit tube 43.
[0022] The sampling device 5 includes an externally threaded sampling tube 51. A first elastic sheet 52 is fixedly connected to the inner side wall of the externally threaded sampling tube 51, and a first elastic ring 53 is fixedly connected to the inner wall of the first elastic sheet 52. A second elastic sheet 54 is fixedly connected to the inner side wall of the externally threaded sampling tube 51, and a second elastic ring 55 is fixedly connected to the inner wall of the second elastic sheet 54. The outer wall of the externally threaded sampling tube 51 is threadedly connected to the outer wall of the limiting tube 43 through an internal thread groove 44. The outer wall of the fixing ring 41 is fixedly connected to the inner wall of the liquid storage box 23 through a connecting hole 25. Before sampling, the sampling device 5 is installed on the connecting device. 4. The external threaded sampling tube 51 is fixed to the limiting tube 43 by its own thread and internal threaded groove 44. During this process, the bottom of the guide bucket 42 will squeeze the first elastic plate 52 and the second elastic plate 54 to make them bend. At this time, the fixed first elastic ring 53 and the second elastic ring 55 inside will expand. The deformed first elastic ring 53 and the second elastic ring 55 will stably fit the first elastic plate 52 and the second elastic plate 54 onto the guide bucket 42. Since the first elastic plate 52 and the second elastic plate 54 are staggered, they will wrap around the outside of the guide bucket 42, thereby preventing urine leakage.
[0023] Working principle:
[0024] Before use, place the support plate 1 on a stable flat surface to provide stable support for the entire sampler. It is difficult to shake before use. When in use, the user controls the position of the sampler by holding the connecting tube 21, which makes it convenient to collect urine.
[0025] When urine enters through the opening at the top of the collection box 23, the diversion device 2 begins to function. The urine will first flow into the collection box 23. The baffle 24 in the collection box 23 can buffer and divert the urine to a certain extent. The urine is then guided by the baffle 24 into the connecting pipe 21 deep inside the collection box 23 to prevent the urine from splashing directly. The diversion pipe 22 in the connecting pipe 21 will guide the flow of urine. This operation makes the urine collection more orderly.
[0026] Then, the leak-proof device 3 works in conjunction. During use, the connecting rod 31 drives the connected components, including the leak-proof column 33, the first sealing ring 34 at both ends, the blocking column 35, and the second sealing ring 36 at both ends, to slide on the inner side wall of the connecting pipe 21. By adjusting their positions, the flow direction of urine can be controlled. When the blocking column 35 and the second sealing ring 36 are both located above the opening of the guide pipe 22, urine will be prevented from flowing out randomly and will be accumulated in the storage box 23, thus achieving a good leak-proof effect. At this time, the urine level will gradually rise above the top of the fixing ring 41 as it accumulates, thereby allowing urine to flow out from the connecting device 41. Once inside the sampling device 5, the sampling process is completed. When the rotating ring 32 is pulled and the connecting rod 31 is pulled down, the blocking column 35 and the second sealing ring 36 open the opening of the guide tube 22, and the urine will flow out through the guide tube 22. This prevents the user from inverting the sampler to pour out excess urine, thus preventing urine dripping during the pouring process. The anti-leakage column 33 and the first sealing ring 34 are located below the blocking column 35 and the second sealing ring 36. During repeated use of the anti-leakage device 3, it can prevent urine dripping from the inlet of the guide tube 22, thereby ensuring the cleanliness of the sampling environment.
[0027] The fixing ring 41 of the connecting device 4 is fixedly connected to the inner wall of the liquid storage box 23 through the connecting hole 25. The guide bucket 42 facilitates the flow of urine. The limiting tube 43 and its internal thread groove 44 are used to install the sampling device 5 and play a connecting and positioning role.
[0028] Before sampling, the sampling device 5 is installed on the connecting device 4. The external threaded sampling tube 51 is fixed to the limiting tube 43 through its own thread and internal thread groove 44. During this process, the bottom of the guide bucket 42 will squeeze the first elastic sheet 52 and the second elastic sheet 54 to make them bend. At this time, the fixed first elastic ring 53 and the second elastic ring 55 inside will expand. The deformed first elastic ring 53 and the second elastic ring 55 will stably fit the first elastic sheet 52 and the second elastic sheet 54 onto the guide bucket 42. Since the first elastic sheet 52 and the second elastic sheet 54 are staggered, they will wrap around the outside of the guide bucket 42, thereby preventing urine leakage and ensuring that the urine sampling operation is completed accurately and hygienically.
[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
