[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, a sampler provided by an embodiment of the utility model comprises a collecting cup 1, the upper opening of the collecting cup 1 is arranged in an arc shape, a hose 2 is installed at the lower outlet of the collecting cup 1, a diversion assembly 3 is provided at one end of the hose 2 away from the collecting cup 1, the diversion assembly 3 comprises a main flow pipe 301, one end of the main flow pipe 301 can be plugged with the hose 2, the other end of the main flow pipe 301 is fixedly connected with a diversion seat 304, the diversion seat 304 is provided with two outlets, a switching valve 305 is rotatably installed on the upper part of the diversion seat 304, one of the outlets of the diversion seat 304 is fixedly connected with a first branch pipe 302, a storage assembly 4 is provided at the lower part of the first branch pipe 302, the storage assembly 4 comprises a sampling tube 402, and the upper part of the sampling tube 402 is screwed to the first branch pipe 302.

[0027] In the above-mentioned sampler, first, the patient aligns the collection cup 1 with the genitals (for men) or fits the genitals (for women). Since the opening of the collection cup 1 is arranged in an arc shape, this design is not only convenient for men to place their genitals, but also suitable for women to fit the genitals, thereby ensuring that urine can accurately flow into the collection cup 1. After the urine flows into the collection cup 1, the urine is guided to the diversion component 3 through the hose 2 at the bottom of the collection cup 1. The diversion seat 304 is designed with two outlets, one connected to the first branch pipe 302, and the other outlet is used to discharge non-midstream urine. During the urine collection process, the user can turn the switching valve 305 as needed. When it is necessary to collect midstream urine, the switching valve 305 is adjusted to close the outlet that is not connected to the first branch pipe 302, and at this time, urine can only flow into the sampling tube 402 through the first branch pipe 302. The sampling tube 402 is used to store midstream urine samples, and its upper part is screwed to the first branch pipe 302 for easy disassembly. When sampling is completed, the user turns the switching valve 305 again to reset it. At this time, the urine will no longer flow into the sampling tube 402, but will be discharged through another outlet of the diverter seat 304, thereby realizing automatic collection and segmentation of urine, allowing the patient to easily and accurately obtain mid-stream urine samples, avoiding the problems of urine spraying and inaccurate sampling.

[0028] In this embodiment, the other outlet of the diverter seat 304 is fixedly connected to the second branch pipe 303, and the lower part of the second branch pipe 303 is fixedly connected to the waste sample tube 404. The lower part of the sampling tube 402 is provided with a placement seat 401, and the sampling tube 402 and the waste sample tube 404 are inserted and placed in the upper groove of the placement seat 401.

[0029] During the urine collection process, after the urine flows into the collection cup 1, it is guided to the main pipe 301 through the hose 2. The main pipe 301 transfers the urine to the diverter seat 304, which plays a key role here. The diverter seat 304 is designed with two outlets, each of which is connected to a different pipe. When urine flows into the diverter seat 304 through the main pipe 301, the user can turn the switching valve 305 as needed to control the flow direction of the urine. If the urine is non-midstream urine in the initial stage or is about to end, the user can adjust the switching valve 305 to make the urine flow to the outlet that is not connected to the first branch pipe 302. At this time, the urine will pass through the second branch pipe 303 and finally flow into the waste sample tube 404. The waste sample tube 404 is designed to temporarily store these non-midstream urine or mucus without mixing with the midstream urine sample.

[0030] During the flow of urine, due to the continuity and fluidity of urine, impurities such as non-midstream urine and mucus will first enter the sampler and be directed to the waste sample tube 404 under the action of the switching valve 305. In this way, when urine enters the midstream, the switching valve 305 is adjusted again, and the midstream urine is directed to the first branch pipe 302 and finally flows into the sampling tube 402.

[0031] In this embodiment, the switching valve 305 includes a valve disc 3052, which is rotatably installed inside the diverter seat 304. A right-angle channel 3053 is opened inside the valve disc 3052. The valve disc 3052 movably penetrates the main pipe 301 at the entrance of the diverter seat 304 and the first branch pipe 302 at one of the outlets of the diverter seat 304 through the right-angle channel 3053, or the valve disc 3052 movably penetrates the main pipe 301 at the entrance of the diverter seat 304 and the second branch pipe 303 at the other outlet of the diverter seat 304 through the right-angle channel 3053. The upper part of the valve disc 3052 extends through the diverter seat 304 to the outside and is fixedly connected to the turntable 3051.

[0032] During the urine sampling process, urine first flows into the diverter seat 304 through the main flow pipe 301. At this time, the position of the valve disc 3052 determines the flow direction of urine. When the valve disc 3052 is in a certain position, the right-angle channel 3053 inside it is aligned with the main flow pipe 301 and the first branch flow pipe 302 to form a flow path. In this way, urine can pass through the main flow pipe 301 and the right-angle channel 3053 of the valve disc 3052, and finally flow into the first branch flow pipe 302, and then enter the sampling tube 402.

[0033] When the urine flow direction needs to be switched, the user only needs to rotate the turntable 3051. The turntable 3051 is fixedly connected to the upper part of the valve disc 3052, so rotating the turntable 3051 will drive the valve disc 3052 to rotate inside the diverter seat 304. As the valve disc 3052 rotates, the right-angle channel 3053 inside it will gradually stagger with the first branch pipe 302 and align with the second branch pipe 303. In this way, the flow direction of urine has changed, and the urine flowing into the main pipe 301 will now pass through the right-angle channel 3053 of the valve disc 3052, and finally flow into the second branch pipe 303, and then enter the waste sample tube 404. In this way, the switching valve 305 can easily switch the urine flow direction. The user can adjust the position of the valve disc 3052 by rotating the turntable 3051 as needed, thereby controlling whether the urine flows into the sampling tube 402 or the waste sample tube 404. This design not only improves the accuracy of urine sampling, but also makes the sampling process more flexible and convenient.

[0034] In this embodiment, the upper part of the sampling tube 402 is fixedly connected with a sealing tube 403, and the sealing tube 403 includes a tube body 4031. A piston 4033 is slidably installed at the bottom of the tube body 4031 through a spring 4032. The piston 4033 movably blocks the tube body 4031, and a plurality of transverse channels 4034 are provided at the lower part of the piston 4033. The lower part of the first branch pipe 302 is threaded with the tube body 4031, and the lower part of the first branch pipe 302 is fixedly connected with a tapered tube 306. The lower part of the tapered tube 306 is pressed and contacted with the upper part of the piston 4033. The piston 4033 is driven by the tapered tube 306 to overcome the pulling force of the spring 4032 and move downward. The lower part of the tapered tube 306 is provided with an output port 307.

[0035] The sealing tube 403 at the top of the sampling tube 402 is designed to ensure the purity and accuracy of the urine sample during the sampling process. The sealing tube 403 includes a tube body 4031, and the bottom of the tube body 4031 is connected to the piston 4033 through a spring 4032. The piston 4033 can slide in the tube body 4031 and realize the function of actively blocking the tube body 4031 through the power of the spring 4032. At the same time, a plurality of transverse channels 4034 are also provided at the bottom of the piston 4033, and these channels play a key role when the piston 4033 moves. The lower part of the first branch pipe 302 is screwed with the tube body 4031 of the sealing tube 403 to ensure that urine can flow smoothly into the sealing tube 403. In addition, a tapered tube 306 is fixedly connected to the lower part of the first branch pipe 302, and the lower part of the tapered tube 306 is pressed and contacted with the upper part of the piston 4033. This design makes it possible for the special shape of the conical tube 306 to generate a downward pressure when urine flows into the conical tube 306 through the first branch tube 302, driving the piston 4033 to move downward to overcome the pulling force of the spring 4032. As the piston 4033 moves downward, the originally blocked tube body 4031 is opened, and urine can enter the sampling tube 402 through the transverse channel 4034. At the same time, the output port 307 at the bottom of the conical tube 306 will also gradually open as the piston 4033 moves downward, ensuring that urine can be discharged smoothly. When the urine flow stops or the sampling is completed, the pulling force of the spring 4032 will cause the piston 4033 to move up again, re-block the tube body 4031, and prevent urine from leaking. Through such a design, the sealing tube 403, the piston 4033, the conical tube 306 and the transverse channel 4034 work together to realize the automatic sampling and sealing function of urine. This working principle not only ensures the purity and accuracy of the urine sample, but also improves the efficiency and convenience of sampling.

[0036] When in use, the patient aligns the collection cup 1 with the genitals (for men) or fits the pubic region (for women). Since the opening of the collection cup 1 is arranged in an arc shape, this design is not only convenient for men to place their genitals, but also suitable for women to fit the pubic region, thereby ensuring that urine can accurately flow into the collection cup 1. After the urine flows into the collection cup 1, the urine is guided to the diversion assembly 3 through the hose 2 at the bottom of the collection cup 1. The diversion seat 304 is designed with two outlets, one connected to the first branch pipe 302, and the other outlet is used to discharge non-midstream urine. During the urine collection process, the user can turn the switching valve 305 as needed. When it is necessary to collect midstream urine, the switching valve 305 is adjusted to close the outlet that is not connected to the first branch pipe 302, and at this time, urine can only flow into the sampling tube 402 through the first branch pipe 302. The sampling tube 402 is used to store midstream urine samples, and its upper part is screwed to the first branch pipe 302 for easy disassembly. When sampling is completed, the user turns the switching valve 305 again to reset it. At this time, the urine will no longer flow into the sampling tube 402, but will be discharged through another outlet of the diverter seat 304, thereby realizing automatic collection and segmentation of urine, allowing the patient to easily and accurately obtain mid-stream urine samples, avoiding the problems of urine spraying and inaccurate sampling.
