Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a first-stage 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 urine collection, different urine samples are collected depending on the testing requirements. For example, the first urine stream, typically the first 20 to 30 ml, contains higher concentrations of analytes related to human oncovirus and Chlamydia trachomatis DNA than the second urine stream. Furthermore, the first urine stream can help detect prostate cancer-specific DNA, RNA, proteins, and metabolites.

[0004] For the first-pass urine collector, it is the first time for many examinees to use the device during its use. During this process, the convenience of using the device directly affects the accuracy of urine collection, that is, how to ensure that the collected urine is the real first-pass urine, rather than the second-pass or urine after the second-pass, which directly affects the accuracy of the detection structure.

[0005] In this regard, for example, the announcement number CN 215306137 U discloses a disposable urine sampler, which includes a trumpet-shaped urine flow channel tube, and a liquid diverter mounting cover vertically mounted on the small end of the urine flow channel tube; a liquid diverter, including a barrier section, a diversion tube and a diversion bottle; the barrier section is a hexahedron with no face on one side and a hollow cavity, and the outer wall of the barrier section is in close contact with the inner wall of the liquid diverter mounting cover; a diversion port is provided on the bottom surface of the barrier section, and the outer periphery of the diversion port is downwardly connected to the diversion tube, and the diversion bottle is mounted on the outer side of the lower part of the diversion tube; a hole is provided on the top surface where the top of the outer tube is connected to the peripheral wall of the diversion tube; and a urine collection tube. The cooperation of the above components allows the first section of urine to accurately enter the urine collection tube. However, it has been found through actual use that the above urine sampler has the following problems:

[0006] First, the liquid diverter can move within the inner cavity of the collector body and the urine collection tube along the depth direction of the urine collection tube. After the collector body and the urine collection tube are assembled before sampling, part of the liquid diverter is located in the collector body, and the other part is located in the urine collection tube. During the first urine collection process, the large end of the collector body needs to penetrate the internal cavity of the barrier section to ensure that the first urine enters the urine collection tube. However, for the urine collection tube in the initial state, since there is no urine in it, the bottom of the liquid diversion tube has no strong support. At this time, the bottom of the entire liquid diverter will directly contact the bottom wall of the inner cavity of the urine collection tube. At this time, if it is to be ensured that the large end of the collector body passes through the internal cavity of the barrier section, it is necessary to design the barrier section of the liquid diverter to be relatively long, that is, to increase the size of the entire liquid diverter to meet the use requirements. Otherwise, it is very likely that the internal cavity of the barrier section will be lower than the large end of the collector body, resulting in urine not being able to enter the urine collection tube. In this case, the corresponding required length of the collector body will also increase synchronously. For urine collectors that are generally disposable, the increase in structural size will directly lead to the difficulty of medical waste treatment in the later stage. Therefore, for the urine collector in the above-mentioned public technology, it is difficult to take into account both reducing the difficulty of medical waste treatment and ensuring normal urine collection.

[0007] Secondly, the main body of the collector adopts a trumpet-shaped urine flow tube. Although it can theoretically meet the needs of both men and women, during the use of women, on the one hand, the entire liquid collection tube needs to be placed horizontally. On the other hand, during the sampling process of women, the hands are held on the urine flow tube, and it is difficult to avoid urine from flowing onto the hands and the outer wall of the urine collection tube and the collection tube body. On the one hand, this will cause contamination, and on the other hand, it will mainly cause urine loss, making it difficult to ensure that the urine finally collected belongs to the first urine, which directly affects the accuracy of the test results.

[0008] In summary, in order to address the problems existing in the currently used urine collectors, their structures need to be further optimized and improved. Utility Model Content

[0009] The purpose of the utility model is to provide a first-stage urine collector to solve the technical problem of optimizing its overall performance.

DETAILED DESCRIPTION

[0038] 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.

[0039] Example 1: Please refer to Figures 1 to 6 As shown, this embodiment provides a first-stage urine collector, comprising: a urine collection tube body 1, a funnel and a floating core rod for use together.

[0040] Specifically, the first is the urine collection tube body 1:

[0041] It has a hollow columnar collection chamber 11 and an open mouth connected to the columnar collection chamber 11; the urine collection tube body 1 here can be made of a transparent material so that the person being examined can keep an eye on the urine collection situation in the columnar collection chamber 11 at any time. To illustrate from an angle that is convenient for processing and forming, the columnar collection chamber 11 in this embodiment is a cylindrical cavity. On the one hand, the open mouth is used to connect a funnel, and on the other hand, it can also be equipped with a cap after the urine collection is completed. The urine collection tube body 1 of this embodiment can also be designed with a scale on the outer wall.

[0042] Next, the funnel includes a connecting portion 21 for connecting to the circumferential outer wall of the open opening, and a liquid inlet nozzle 22 and a liquid outlet nozzle 23 connected to the side wall of the connecting portion 21 and communicating with the inner cavity of the connecting portion 21. The connecting portion 21 and the open opening can be screwed together. Here, the open opening of the urine collection tube body 1 can be inserted into the connecting portion 21, or the connecting portion 21 can be inserted into the open opening. This embodiment does not limit this.

[0043] Among them, the liquid inlet nozzle 22 preferably adopts a trumpet-shaped structure, while the shape of the liquid outlet spout 23 can simply be similar to the water outlet spout of a kettle to meet the usage requirements of this embodiment. In an optional implementation, the axis of the liquid inlet nozzle 22 and the liquid outlet spout 23 are consistent and form an angle of approximately 35° with the connecting part 21.

[0044] It should be noted that during the initial use of the urine collector, the liquid inlet nozzle 22 is directly held by the human hand. To prevent the liquid inlet nozzle 22 from slipping out of the hand, an anti-slip structure 24 is provided on the outer wall of the liquid inlet nozzle 22. The anti-slip structure 24 can be an anti-slip pattern or an anti-slip protrusion, which is not an absolute limitation in this embodiment.

[0045] A hollow cavity 25 is also formed in the connecting portion 21. On the one hand, the hollow cavity 25 is used to simultaneously connect the liquid inlet nozzle 22 and the liquid outlet spout 23. On the other hand, it cooperates with the columnar collecting cavity 11 to form a cavity for accommodating the floating core rod.

[0046] Based on the above structure, let's talk about the floating mandrel:

[0047] The floating core rod includes a core rod body 31 arranged between the columnar collecting cavity 11 and the connecting portion 21, and a first drainage portion 32 and a second drainage portion 33 formed on a portion of the core rod body 31 away from the bottom of the columnar collecting cavity 11; the first drainage portion 32 is located between the core rod body 31 and the second drainage portion 33.

[0048] In theory, for the aforementioned floating mandrel, whether it is the mandrel body 31, the first drainage portion 32, the second drainage portion 33, or the hollow cavity 25 of the connecting portion 21, 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 connecting portion 21. 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 liquid inlet nozzle 22 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, communicating with both the guide port and the columnar collection chamber 11.

[0049] Regarding the core rod body 31 used in this embodiment, an annular cavity 35 surrounding the liquid channel 36 is further provided at the portion thereof inserted into the columnar collecting cavity 11 of the urine collecting tube body 1, and the end of the core rod body 31 facing away from the connecting portion 21 is formed as an open end connected to both the liquid channel 36 and the annular cavity 35.

[0050] Based on the above structure, it is also necessary to explain that, in this embodiment, it is taken into account that in the process of separating the funnel from the urine collecting tube body 1 by rotation, the core rod body 31 can leave the urine collecting tube body 1 together with the funnel to prevent relative rotation between the funnel and the urine collecting tube body 1. The hollow cavity 25 of the connecting part 21, the core rod body 31, the first drainage part 32 and the second drainage part 33 used here all have a part of the side wall of the cylindrical structure cut off to form a limiting plane 37.

[0051] Furthermore, an annular stop ring 38 protrudes from the inner wall of the connecting portion 21 and is adapted to abut the end face of the core rod body 31 facing the first drainage portion 32. The stop ring 38 is located below the portion of the connecting portion 21 where the inner cavity connects to the liquid inlet nozzle 22 and the liquid outlet spout 23, respectively. Regarding the stop ring 38, it should be noted that when the connecting portion 21 is screwed into place with the urine collection tube 1, 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.

[0052] It should be noted that, in this embodiment, at least one limiting portion is provided on the inner wall of the connecting portion 21 for connecting to the second drainage portion 33 and for maintaining the liquid inlet 34 in a connected state with the liquid inlet nozzle 22 before urine is collected.

[0053] 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 connecting portion 21.

[0054] In more detail, the cone block 39 is a semi-conical structure; and the end surface of the cone block 39 facing the columnar collection chamber 11 is a cone surface, and the end surface of the cone block 39 facing away from the columnar collection chamber 11 is a flat end surface. Under this structure, when one end of the floating core rod is inserted into the connecting part 21 of the funnel, the floating core rod is inserted from the connecting part 21 toward one end of the urine collection tube body 1. At this time, since the end surface of the cone block 39 facing the cylindrical collection chamber 11 is a cone surface, the top wall of the second drainage part 33 corresponding to the liquid inlet 34 can be instantly squeezed and deformed along the above-mentioned cone surface. Therefore, after the second drainage part 33 overcomes the effect of the cone surface, when the flat end surface of the cone block 39 supports the inner top wall of the liquid inlet 34, the assembly of the floating core rod and the connecting part 21 can be completed. In addition, without applying force to the floating core rod, the floating core rod will not detach from the connecting part 21. In this way, when the connecting part 21 and the urine collection tube body 1 are assembled in place, the floating core rod will not fall directly onto the inner bottom wall of the cylindrical collection chamber 11 of the urine collection tube body 1. 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 liquid inlet nozzle 22 are kept in communication before urine is collected.

[0055] 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 wall of the columnar collection chamber 11, and there is no need to design an additional structure to cooperate with the cone block 39 on the floating core rod.

[0056] In another alternative embodiment, the outer wall of the second drainage portion 33 is provided with a T-shaped guide groove adapted to fit within the conical block 39. The end of the T-shaped guide groove, facing away from the cylindrical collection chamber 11, is a top wall adapted to be supported by the flat end surface of the conical block 39. In other words, the conical block 39 and the T-shaped guide groove cooperate to positionally engage the floating mandrel with the connecting portion 21. While the structural design is more complex than in the previous embodiment, it does not affect its effectiveness.

[0057] In summary, for the first-stage urine collector of this embodiment,

[0058] When the outer wall of the core rod body 31 is separated from the stop ring 38, the urine entering the funnel through the liquid inlet nozzle 22 flows into the columnar collecting chamber 11 through the liquid inlet 34 and the liquid channel 36; when the outer wall of the core rod body 31 abuts against the stop ring 38, the liquid inlet nozzle 22 is aligned with the first drainage part 32, and the urine entering the funnel through the liquid inlet nozzle 22 flows out from the liquid outlet spout 23 along the circumference of the first drainage part 32.

[0059] Example 2: Please refer to Figures 1 to 7 As shown, based on the first-stage urine collector of Example 1, considering that the overall shape and structure of the liquid inlet nozzle 22 of the first-stage urine collector of the embodiment are more suitable for male use, and there is a problem of urine leakage during use by women, this embodiment is mainly improved from the perspective of facilitating use by women.

[0060] To meet these requirements, the liquid inlet nozzle 22 employed in this embodiment is removably connected to a connecting tube 4. A urine collection cup 5 is attached to the end of the connecting tube 4, distal from the liquid inlet nozzle 22. A hand-held handle 6 is also attached to the outer wall of the urine collection cup 5. The connecting tube 4 optionally connects to the liquid inlet nozzle 22 via a connector. Specifically, the urine collection cup 5 has a large-diameter urine receiving opening, primarily to ensure that the first portion of urine enters the urine collection cup 5.

[0061] Based on the above, during use, one hand can hold the handle 6, aligning the urine collection cup 5 with the female urinary opening, while the other hand holds the liquid inlet nozzle 22. The connecting tube 4 allows the urine collection tube 1 to be moved away from the female urinary opening to prevent urine from splashing onto the urine collection tube 1. This allows urine that enters the urine collection cup 5 directly to flow through the connecting tube 4 into the funnel and then partially into the urine collection tube 1. After collecting the initial amount of urine from the urine collection tube 1, the connecting tube 4 can be separated from the liquid inlet nozzle 22 and the connecting tube 4 and urine collection cup 5 can be discarded.

[0062] In summary, the first-pass urine collector used in this embodiment can not only meet the needs of collecting the first-pass urine of men, but also facilitate the collection of the first-pass urine of women, and improves the accuracy and convenience of urine collection for women.
