Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a segmented urine collector. Background Art

[0002] Urine tests can reveal the state of human function and are commonly used for health checkups and disease diagnosis. The current urine test process is broadly divided into sampling and testing and analysis. Testing and analysis are performed by professional medical staff and specialized equipment, while sampling must be completed by the patient or examinee themselves.

[0003] During the urine collection process, the amount of urine that needs to be collected varies depending on the testing needs. For example, the first urine stream is usually the first 20 to 30 ml of urine flow. Testing this stream can not only indicate urethritis in the patient, but also contains higher concentrations of analytes related to human tumor virus and Chlamydia trachomatis DNA than the second urine stream. In addition, the first urine stream also helps to detect prostate cancer-specific DNA, RNA, proteins, and metabolites. The second urine stream is usually the middle 30 to 40 ml. Testing the second urine stream can reflect the condition of the kidneys, while the second urine stream is usually the final 5 to 10 ml. Testing the second urine stream can reflect the condition of the bladder. If all three streams of urine are abnormal, it indicates that the patient may have problems such as pyelonephritis, glomerulitis, or kidney tumors.

[0004] Therefore, the urine collectors currently used in conventional methods can basically only meet the needs of collecting one section of urine, or when collecting, for example, two sections of urine, it is inconvenient to separate and store the two sections of urine separately. For example, the segmented sealed urine collection cup disclosed in publication number CN107807020A includes a first urine collection container and a second urine collection container that can be used to store different sections of urine respectively. After the urine is collected, it is difficult to seal the urine in the two urine collection containers separately. In the actual hospital examination process, after the patient completes the sampling, the urine needs to be temporarily stored in a sealed tube on a fixed shelf. After the medical staff completes the urine analysis of a fixed batch on the detection machine, the urine sample is replaced and sampled. Therefore, in order to avoid urine overflow or urine contamination by impurities, a sealed tube is required for storage. Therefore, the urine sampler in the above-mentioned publication document is difficult to meet the actual usage needs.

[0005] In summary, in order to address the problems existing in the currently used segmented urine collector, its structure needs to be further optimized and improved. Utility Model Content

DETAILED DESCRIPTION

[0039] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0040] Example 1: Please refer to Figures 1 to 10 As shown, this embodiment provides a segmented urine collector, comprising: a segmented urine collector comprising: a first-stage urine collection component for collecting the first stage of urine discharged from a human body and a middle-stage urine collection component for collecting the middle stage of urine discharged from a human body. In other words, the segmented urine collector of this embodiment can simultaneously collect and store two different stages of urine discharged from a human body.

[0041] Regarding the general structure of the first-stage urine collection component and the middle-stage urine collection component used in this embodiment, a specific optional implementation is given with reference to the accompanying drawings:

[0042] First, the first-stage urine collection assembly includes a first-stage urine collection tube 100 having a first-stage liquid storage cavity 101, a first-stage funnel 203 detachably connected to the first-stage urine collection tube 100, and a first-stage floating plug for isolating the urine flow between the first-stage funnel 203 and the first-stage liquid storage cavity 101. The first-stage funnel 203 includes a first connecting portion 200 detachably connected to the first-stage urine collection tube 100, and a first liquid inlet nozzle 201 and a first liquid outlet nozzle 202 connected to a pair of oppositely disposed side walls of the first connecting portion 200 and communicating with the inner cavity of the first connecting portion 200.

[0043] Secondly, the mid-section urine collection component includes a mid-section urine collection tube 300 with a mid-section liquid storage cavity 301, a mid-section funnel 401 detachably connected to the mid-section urine collection tube 300, and a mid-section floating plugging member for isolating the urine flow between the mid-section funnel 401 and the mid-section liquid storage cavity 301; wherein the mid-section funnel 401 includes a second connecting portion 402 detachably connected to the mid-section urine collection tube 300, and a second liquid inlet nozzle 403 and a second liquid outlet nozzle 404 connected to a pair of oppositely distributed side walls of the second connecting portion 402 and connected to the inner cavity of the second connecting portion 402; the second liquid inlet nozzle 403 is detachably connected to the first liquid outlet nozzle 202.

[0044] In this embodiment, the first-section urine collection tube 100 and the middle-section urine collection tube 300 can be made of transparent materials, so that the examinee can pay attention to the urine collection status at any time.

[0045] Furthermore, it should be noted that the first urine collection tube 100 is formed with an open opening for threaded engagement with the first connecting portion 200; and the middle urine collection tube 300 is formed with an open opening for threaded engagement with the second connecting portion 402; and the open openings of the first urine collection tube 100 and the middle urine collection tube 300 are each detachably connected to a cap. It should be noted that the caps are used after urine collection is completed in the first urine collection tube 100 and the middle urine collection tube 300, by separating the first funnel 203 from the first urine collection tube 100 and then placing the cap over the open opening of the first urine collection tube 100. Similarly, the middle funnel 401 is separated from the middle urine collection tube 300 and then placing the cap over the open opening of the middle urine collection tube 300. In this way, for the tube body used to collect the first-stream urine and the middle-stream urine, it can be ensured that the urine is effectively preserved before being tested, and the urine will not overflow or be contaminated.

[0046] Based on the above structure, it should be further explained that during the use of the overall segmented urine collector, urine enters the first connecting portion 200 from the first liquid inlet 201. After the urine in the first urine collection tube 100 is collected, the urine then enters the second liquid inlet 403 through the first liquid outlet 202, and then enters the middle urine collection tube 300. After the urine in the middle urine collection tube 300 is collected, the excess urine is discharged from the second liquid outlet 404. In this process, in order to prevent the urine from overflowing from the first liquid inlet 201 as much as possible, the first liquid inlet 201 preferably adopts a trumpet-shaped structure. It should be noted that during the use of the urine collector, the human hand directly grasps the first liquid inlet 201. In order to prevent the first liquid inlet 201 from slipping out of the hand, an anti-slip structure 24 is provided on the outer wall of the first liquid inlet 201. The anti-slip structure 24 can be an anti-slip pattern or an anti-slip protrusion, which is not absolutely limited in this embodiment.

[0047] Furthermore, in order to improve the collection efficiency of the urine as a whole, the axes of the first liquid inlet nozzle 201 and the first liquid outlet nozzle 202 are aligned and the included angle between each of the first liquid inlet nozzle 201 and the first liquid outlet nozzle 202 and the first connecting portion 200 is in the range of 30° to 45°. In addition, the axes of the second liquid inlet nozzle 403 and the second liquid outlet nozzle 404 are aligned and the included angle between each of the second liquid inlet nozzle 403 and the second liquid outlet nozzle 404 and the second connecting portion 402 is in the range of 30° to 45°.

[0048] In addition, in order to facilitate the use of the first urine collection assembly and the middle urine collection assembly together, in an optional implementation, the first liquid outlet nozzle 202 and the second liquid inlet nozzle 403 are both in the form of a columnar body.

[0049] Based on the above, in combination with the drawings, an optional implementation is described as follows. The second liquid inlet nozzle 403 is internally formed with a slot suitable for the partial insertion of the first liquid outlet nozzle 202. In addition, the inner cavity of the slot is formed with an annular limiting groove 601, and the outer side wall of the first liquid outlet nozzle 202 is formed with an annular limiting boss 602 suitable for being clamped into the annular limiting groove 601. In this structure, the first liquid outlet nozzle 202 and the second liquid inlet nozzle 403 are directly inserted, and when the annular limiting boss 602 and the annular limiting groove 601 are inserted into position, the first liquid outlet nozzle 202 and the second liquid inlet nozzle 403 form a stable cooperation relationship, and when it is necessary to separate the two, a slight pulling force can be applied to separate them.

[0050] Based on the above structure, the following is to be described about the first floating plugging member and the middle floating plugging member.

[0051] In an optional implementation, the first floating plugging member is in the form of a floating ball 700, and the first floating plugging member is suitable for moving between the first liquid storage cavity 101 and the inner cavity of the first connecting portion 200. In addition, the inner cavity of the first connecting portion 200 is formed with a first annular baffle 205 suitable for abutting cooperation with the first floating plugging member, and the first annular baffle 205 is located below the connection between the first connecting portion 200 and the first liquid inlet nozzle 201 and the first liquid outlet nozzle 202.

[0052] For the first floating plugging member with the above structure, as the volume of the urine entering the first liquid storage cavity 101 gradually increases, the floating ball 700 gradually rises under the buoyancy of the urine. When the floating ball 700 moves up to the first annular baffle 205, it indicates that the storage amount of the urine in the first liquid storage cavity 101 has reached the standard, and the cooperation between the floating ball 700 and the first annular baffle 205 forms a partition between the first liquid storage cavity 101 and the first liquid inlet nozzle 201. In this way, the urine can enter the first liquid outlet nozzle 202 and then enter the middle liquid storage cavity 301.

[0053] The middle floating seal can also be a ball float 700, adapted to move between the middle liquid storage chamber 301 and the inner cavity of the second connecting portion 402. The inner cavity of the second connecting portion 402 forms a middle annular baffle 405 for abutting the middle floating seal. This baffle 405 is located below the connection between the second connecting portion 402 and the second liquid inlet nozzle 403 and the second liquid outlet nozzle 404. The implementation principle of the ball float 700 is similar to that of the first floating seal and will not be further described here.

[0054] In a second optional implementation, at least one of the first-section floating blocking member and the middle-section floating blocking member may be a blocking member with other structures, such as a floating core rod 800 .

[0055] Next, the implementation principle will be described by taking the floating core rod 800 in conjunction with the first-stage urine collection tube 100 and the first-stage funnel 203 as an example with reference to the accompanying drawings:

[0056] The floating core rod 800 includes a core rod body 31 arranged between the first section liquid storage chamber 101 and the first connecting part 200, and a first drainage part 32 and a second drainage part 33 formed on the part of the core rod body 31 away from the bottom of the first section liquid storage chamber 101; the first drainage part 32 is located between the core rod body 31 and the second drainage part 33.

[0057] In theory, for the floating mandrel 800, whether it is the mandrel body 31, the first drainage portion 32, the second drainage portion 33, or the hollow cavity 25 of the first connecting portion 200, all can adopt a standard cylindrical structure. It should be noted that the outer diameter of the first drainage portion 32 is smaller than the outer diameters of the mandrel body 31 and the second drainage portion 33, and the outer wall surface of the second drainage portion 33 is in close contact with the inner wall surface of the first connecting portion 200. The bottom surface of the second drainage portion 33 is provided with a guide port, and the end surface of the second drainage portion 33 facing the first liquid inlet nozzle 201 is also provided with a liquid inlet 34 connected to the guide port. A liquid channel 36 is also provided between the first drainage portion 32, the second drainage portion 33, and the mandrel body 31, which is connected to both the guide port and the first-stage liquid storage chamber 101.

[0058] Regarding the core rod body 31 used in this embodiment, the portion thereof inserted into the first liquid storage chamber 101 of the first urine collection tube 100 is further provided with an annular cavity 35 surrounding the liquid channel 36, and the end of the core rod body 31 facing away from the first connecting portion 200 is formed as an open end connected to both the liquid channel 36 and the annular cavity 35.

[0059] Based on the above structure, it is also necessary to explain that, in this embodiment, taking into account that in the process of separating the funnel from the first-section urine collection tube 100 by rotation, the core rod body 31 can leave the first-section urine collection tube 100 together with the funnel to prevent relative rotation between the funnel and the first-section urine collection tube 100, the hollow cavity 25, the core rod body 31, the first drainage part 32 and the second drainage part 33 of the first connecting part 200 used here are all cut off a part of the side wall of the cylindrical structure to form a limiting plane 37.

[0060] In addition, an annular baffle 38 is protruding from the inner wall of the first connecting portion 200 and is suitable for abutting the end face of the core rod body 31 facing the first drainage portion 32. The annular baffle 38 is located below the portion of the inner cavity of the first connecting portion 200 where it connects to the first liquid inlet nozzle 201 and the first liquid outlet nozzle 202. Regarding the first annular baffle 205 herein, it should be noted that when the first connecting portion 200 and the first-section urine collection tube 100 are screwed into place, the floating core rod, supported by the buoyancy of the urine in the cylindrical collection chamber 11, can abut the end face of the stop ring 38 facing away from the second drainage portion 33.

[0061] It should be noted that, in this embodiment, at least one limiting portion is provided on the inner wall of the first connecting portion 200 for connecting to the second drainage portion 33 and for maintaining the liquid inlet 34 in communication with the first liquid inlet nozzle 201 before urine is collected.

[0062] Here, an optional implementation is given as an example with reference to the accompanying drawings. The limiting portion is a cone block 39 protruding from the inner cavity wall of the first connecting portion 200.

[0063] In more detail, the cone block 39 is a semi-conical structure; and the end face of the cone block 39 facing the first section liquid storage chamber 101 is a cone face, and the end face of the cone block 39 facing away from the first section liquid storage chamber 101 is a flat end face. Under this structure, when one end of the floating core rod 800 is inserted into the first connecting portion 200 of the funnel, the floating core rod 800 is inserted from the first connecting portion 200 toward one end of the first section urine collection tube 100. At this time, since the end face of the cone block 39 facing the first section liquid storage chamber 101 is a cone face, the top wall of the liquid inlet 34 of the second drainage portion 33 can produce instantaneous extrusion deformation along the above-mentioned cone face. Therefore, after the second drainage portion 33 overcomes the effect of the cone face, when the flat end face of the cone block 39 supports the inner top wall of the liquid inlet 34, the floating core rod 800 can be completed. 00 is assembled with the first connecting part 200, and when no force is applied to the floating core rod 800, the floating core rod 800 will not be separated from the first connecting part 200. In this way, when the first connecting part 200 and the first-section urine collection tube 100 are assembled in place, the floating core rod 800 will not fall directly onto the inner bottom wall of the first-section liquid storage cavity 101 of the first-section urine collection tube 100. On this basis, through the ingenious design of the position of the cone block 39, it can be ensured that the liquid inlet 34 and the first liquid inlet nozzle 201 are kept in communication before urine is collected.

[0064] In addition, for the design of the above-mentioned cone block 39, the liquid inlet 34 is directly used to cooperate with the cone block 39. In this way, it is only necessary to directly design the cone block 39 on the inner cavity wall of the first section of the liquid storage cavity 101, and there is no need to design an additional structure on the floating core rod 800 to cooperate with the cone block 39.

[0065] In summary, for the segmented urine collector of this embodiment, the first-stage urine collection component and the middle-stage urine collection component can simultaneously meet the collection needs of different sections of urine; furthermore, regardless of the first-stage urine collection component or the middle-stage urine collection component, the detachable cooperation of the funnel and the urine collection tube allows the funnel and the urine collection tube to be disassembled after the urine collection is completed, making it convenient to cover the urine collection tube with a cap, thereby ensuring that the collected urine can be effectively preserved before testing.

[0066] Example 2: Please refer to Figure 11 As shown, based on the segmented urine collector of Example 1, the segmented urine collector provided in this embodiment further includes a final urine collection assembly connected to the second liquid outlet nozzle 404 of the middle urine collection tube 300. The final urine collection assembly is mainly used to collect the final urine, thereby achieving a complete three-stage urine sampling.

[0067] Specifically, the terminal urine collection assembly used in this embodiment includes a terminal urine collection tube 900 having a terminal liquid storage cavity 901, and a terminal funnel 1001 detachably connected to the terminal urine collection tube 900. The terminal funnel 1001 includes a third connecting portion 1002 detachably connected to the terminal urine collection tube 900, and a third liquid inlet nozzle 1003 connected to a side wall of the third connecting portion 1002 and communicating with the inner cavity of the third connecting portion 1002. The third liquid inlet nozzle 1003 is detachably coupled to the second liquid outlet nozzle 404. The specific coupling structure between the third liquid inlet nozzle 1003 and the second liquid outlet nozzle 404 can be selected from the coupling structure between the first liquid outlet nozzle 202 and the second liquid inlet nozzle 403.

[0068] It should be noted that, for the segmented urine collector of this embodiment, the third connecting portion 1002 is no longer provided with a corresponding liquid outlet. This is because for the general population, the total amount of urine is within a certain range. After the collection of the first and middle urine segments, the remaining urine is the final urine segment, and the remaining amount is not particularly large. Therefore, a corresponding liquid outlet is no longer required. Accordingly, there is no need to design a floating plugging member in the final urine collection tube 900. Instead, the remaining urine except the first and middle urine segments is directly collected into the final urine collection tube 900. Of course, the final urine collection tube 900 of this embodiment can also be configured with a detachable cap to facilitate the sealing and storage of the final urine in the final urine collection tube 900.

[0069] In this regard, combined with the actual segmentation of urine, in an optional implementation, the volume of the first urine collection tube 100 is smaller than the volume of the middle urine collection tube 300, and the volume of the middle urine collection tube 300 is smaller than the volume of the last urine collection tube 900.
