Detailed Description

For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.

The structure of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the sampler provided by the embodiment of the utility model comprises a collecting cup 1, wherein an opening at the upper part of the collecting cup 1 is arc-shaped, a hose 2 is inserted and installed at an outlet at the lower part of the collecting cup 1, a shunt component 3 is arranged at one end of the hose 2, which is far away from the collecting cup 1, the shunt component 3 comprises a main flow pipe 301, one end of the main flow pipe 301 can be inserted and connected with the hose 2, a shunt seat 304 is fixedly connected with the other end of the main flow pipe 301, two outlets are formed in the shunt seat 304, a switching valve 305 is rotatably installed at the upper part of the shunt seat 304, a first shunt pipe 302 is fixedly connected with one outlet of the shunt seat 304, a storage component 4 is arranged at the lower part of the first shunt pipe 302, the storage component 4 comprises a sampling pipe 402, and the upper part of the sampling pipe 402 is in threaded connection with the first shunt pipe 302.

In one such sampler, first, the patient aligns the collection cup 1 with the genitalia (for men) or fits the pudendum (for women). Because the opening of the collecting cup 1 is arc-shaped, the design is convenient for men to place genitals and is also suitable for women to attach to pudendum, thereby ensuring that urine can accurately flow into the collecting cup 1. After the urine flows into the collection cup 1, the urine is guided to the diverting assembly 3 through the hose 2 at the lower part of the collection cup 1. The diverter seat 304 is configured with two outlets, one connected to the first diverter tube 302 and the other for discharging non-midstream urine. During urine collection, the user can rotate the switching valve 305 as desired. When mid-section urine needs to be collected, switch valve 305 is adjusted to close the outlet port not connected to first shunt tube 302, at which point urine can only flow into sampling tube 402 through first shunt tube 302. The sampling tube 402 is used for storing a middle-section urine sample, and the upper part of the sampling tube is in threaded connection with the first branch flow tube 302, so that the sampling tube is convenient to detach. After the sampling is completed, the user rotates the switching valve 305 again to reset the switching valve, at this time, urine will not flow into the sampling tube 402 any more, but is discharged through the other outlet of the diversion seat 304, so that automatic collection and segmentation of urine are realized, the patient can easily and accurately obtain a middle-stage urine sample, and the problems of external spraying and inaccurate sampling of urine are avoided.

In this embodiment, the other outlet of the shunt seat 304 is fixedly connected with a second shunt tube 303, and the lower portion of the second shunt tube 303 is fixedly connected with a waste sampling tube 404. A placing seat 401 is arranged at the lower part of the sampling tube 402, and the sampling tube 402 and the waste sampling tube 404 are inserted and placed at the upper groove of the placing seat 401.

During urine collection, after urine flows into the collection cup 1, it is guided to the main flow tube 301 through the hose 2. The primary flow tube 301 delivers urine to the diverter seat 304, where the diverter seat 304 plays a key role. The splitter block 304 is designed with two outlets, each of which is connected to a different conduit. When urine flows into the diverting seat 304 through the main flow pipe 301, a user can rotate the switching valve 305 as required to control the flow direction of the urine. If the urine is non-mid-stream urine at the beginning or near the end, the user can adjust the switch valve 305 to direct the urine to an outlet that is not connected to the first shunt tube 302. At this time, urine passes through second branch flow tube 303 and finally flows into waste tube 404. Waste tube 404 is designed to temporarily store these non-mid-stream urine or mucus without mixing with the mid-stream urine sample.

During the flow of urine, impurities such as non-midstream urine and mucus will first enter the sampler due to the continuity and flowability of urine and be directed to waste tube 404 by switching valve 305. Thus, when urine enters the midsection, the switching valve 305 is again adjusted, midsection urine is directed to the first shunt tube 302, and finally flows into the sampling tube 402.

In this embodiment, the switching valve 305 includes a valve disc 3052, the valve disc 3052 is rotatably mounted inside the split-flow seat 304, a right-angle channel 3053 is formed inside the valve disc 3052, the valve disc 3052 movably penetrates through the main flow tube 301 at the inlet of the split-flow seat 304 and the first branch flow tube 302 at one outlet of the split-flow seat 304 through the right-angle channel 3053, or the valve disc 3052 movably penetrates through the main flow tube 301 at the inlet of the split-flow seat 304 and the second branch flow tube 303 at the other outlet of the split-flow seat 304 through the right-angle channel 3053, and the upper portion of the valve disc 3052 extends to the outside through the split-flow seat 304 and is fixedly connected with a turntable 3051.

In the urine sampling process, urine first flows into the shunt seat 304 through the main flow tube 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 particular position, the right angle passage 3053 therein aligns with the main flow tube 301 and the first bypass tube 302 to form a flow path. Thus, urine can flow through the main flow tube 301 and the right-angle passage 3053 of the valve plate 3052, and finally into the first branch flow tube 302 and further into the sampling tube 402.

When the flow direction of urine needs to be switched, the user only needs to rotate the rotary plate 3051. The turntable 3051 is fixedly connected to the upper portion of the valve disc 3052, so that rotating the turntable 3051 drives the valve disc 3052 to rotate inside the split seat 304. As the valve disc 3052 rotates, the right angle channel 3053 therein becomes progressively displaced from the first branch tube 302 and aligns with the second branch tube 303. Thus, the flow direction of urine is changed, and urine flowing from main flow tube 301 passes right-angle passage 3053 of valve plate 3052, and finally flows into second branch flow tube 303, and then into waste tube 404. In this way, the switching valve 305 can easily effect switching of the flow direction of urine. The user can adjust the position of valve disc 3052 by rotating dial 3051 as desired to control the flow of urine into sampling tube 402 or waste tube 404. The design not only improves the accuracy of urine sampling, but also makes the sampling process more flexible and convenient.

In this embodiment, a sealing tube 403 is fixedly connected to the upper portion of the sampling tube 402, the sealing tube 403 includes a tube body 4031, a piston 4033 is slidably mounted at the bottom of the tube body 4031 through a spring 4032, the piston 4033 movably seals the tube body 4031, and a plurality of transverse channels 4034 are formed in the lower portion of the piston 4033. The lower part of the first branch flow pipe 302 is screwed with the pipe body 4031, the lower part of the first branch flow pipe 302 is fixedly connected with the conical pipe 306, the lower part of the conical pipe 306 is in pressing contact with the upper part of the piston 4033, the piston 4033 is driven by the conical pipe 306 to move downwards against the tension of the spring 4032, and the lower part of the conical pipe 306 is provided with the output port 307.

Seal tube 403 in the upper portion of sampling tube 402 is designed to ensure purity and accuracy of the urine sample during sampling. The sealing tube 403 comprises a tube body 4031, and the bottom of the tube body 4031 is connected with a piston 4033 through a spring 4032. The piston 4033 can slide in the tube 4031 and can actively block the tube 4031 by the force of the spring 4032. At the same time, the lower part of the piston 4033 is also provided with a plurality of transverse channels 4034 which play a key role when the piston 4033 moves. The lower part of the first shunt tube 302 is in threaded connection with the tube body 4031 of the sealing tube 403, so that urine can flow into the sealing tube 403 smoothly. In addition, a conical tube 306 is fixedly connected to the lower portion of the first branch flow tube 302, and the lower portion of the conical tube 306 is in pressing contact with the upper portion of the piston 4033. This design allows the particular shape of the conical tube 306 to create a downward pressure as urine flows into the conical tube 306 through the first shunt tube 302, driving the piston 4033 downward against the tension of the spring 4032. As the piston 4033 moves downward, the otherwise occluded tube 4031 is opened and urine is allowed to enter the sampling tube 402 through the transverse channel 4034. Meanwhile, the output port 307 at the lower part of the conical tube 306 is gradually opened along with the downward movement of the piston 4033, so that the urine can be smoothly discharged. When urine flow stops or sampling is completed, the pulling force of the spring 4032 will cause the piston 4033 to move upwards again, resealing the tube 4031 and preventing urine from leaking. By such design, the seal tube 403, piston 4033, conical tube 306 and transverse channel 4034 cooperate together to achieve the automatic sampling and sealing function of urine. The operating principle not only ensures the purity and accuracy of the urine sample, but also improves the sampling efficiency and convenience.

In use, the patient aligns the collection cup 1 with the genitalia (for men) or fits the pudendum (for women). Because the opening of the collecting cup 1 is arc-shaped, the design is convenient for men to place genitals and is also suitable for women to attach to pudendum, thereby ensuring that urine can accurately flow into the collecting cup 1. After the urine flows into the collection cup 1, the urine is guided to the diverting assembly 3 through the hose 2 at the lower part of the collection cup 1. The diverter seat 304 is configured with two outlets, one connected to the first diverter tube 302 and the other for discharging non-midstream urine. During urine collection, the user can rotate the switching valve 305 as desired. When mid-section urine needs to be collected, switch valve 305 is adjusted to close the outlet port not connected to first shunt tube 302, at which point urine can only flow into sampling tube 402 through first shunt tube 302. The sampling tube 402 is used for storing a middle-section urine sample, and the upper part of the sampling tube is in threaded connection with the first branch flow tube 302, so that the sampling tube is convenient to detach. After the sampling is completed, the user rotates the switching valve 305 again to reset the switching valve, at this time, urine will not flow into the sampling tube 402 any more, but is discharged through the other outlet of the diversion seat 304, so that automatic collection and segmentation of urine are realized, the patient can easily and accurately obtain a middle-stage urine sample, and the problems of external spraying and inaccurate sampling of urine are avoided.
