Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a urine collection cup. Background Technology

[0002] In clinical diagnostics and medical research, urine sample collection and processing are fundamental and crucial steps. However, the design of urine collection cups, an indispensable tool in this process, often fails to fully meet the needs of practical use. Currently available urine collection cups generally suffer from insufficient handle length, leading to accidental splashing of urine onto the user's hands during sample collection. This not only inconveniences patients but may also affect the operational experience and hygiene safety of medical staff. Furthermore, existing urine collection cups typically lack filtration designs or effective filtration mechanisms. For example, the prior patent CN205749024U, "Adsorption Filtration Type Random Urine Specimen Collector," uses only a single-layer filter structure made of materials such as sponge, which cannot effectively remove impurities from the urine sample, such as filtering only larger impurities. In certain urine testing scenarios, this may adversely affect subsequent sample analysis, reducing the accuracy and reliability of the test results.

[0003] From a product improvement perspective, these shortcomings actually reveal new areas of demand. Therefore, designing a urine collection cup that effectively addresses these issues and better adapts to the specific requirements of real-world applications has become a pressing technical challenge. Utility Model Content

[0004] To at least partially overcome the problems existing in related technologies, this application provides a urine collection cup that employs a multi-layered filter structure with gradient settings to improve the shortcomings of existing related products and meet the needs of real-world scenarios.

[0005] This application provides a urine collection cup, which includes a cup body and a filter layer structure horizontally disposed within the cup body. The filter layer structure is composed of multiple layers of filter materials with progressively smaller pore sizes stacked from top to bottom. An extendable handle is provided on the side wall of the cup above the filter layer structure, and the fixing point of the extendable handle is far away from the edge of the cup opening; A liquid outlet is provided on the side wall of the cup body below the filter layer structure, and the liquid outlet and the extendable handle are located on opposite sides of the cup body.

[0006] In some possible implementations, the filter layer structure comprises, from top to bottom: a polyethylene mesh layer with a pore size of 1-2 mm, an electrospun hydrophilic membrane layer with a pore size of 0.1 mm, and a glass fiber filter paper layer with a pore size of 20 μm.

[0007] In some possible implementations, the dispensing nozzle is inclined relative to the side wall of the cup; the dispensing pipe of the dispensing nozzle is embedded with a nylon final filter membrane with a pore size of 5μm, which is used to achieve final filtration when urine is poured out.

[0008] In some possible implementations, the end of the dispensing nozzle is provided with a disposable heat-sealed plastic film.

[0009] In some possible implementations, the extendable handle includes: A main rod fixed to the side wall of the cup body; a folding rod hinged to the main rod via a pivot; and a semi-circular baffle at the end of the main rod, wherein the semi-circular baffle is integrally formed with the main rod.

[0010] In some possible implementations, the extendable handle is made entirely of plastic material with a non-slip texture on the surface.

[0011] In some possible implementations, the upper part of the cup is flared.

[0012] In some possible implementations, a flow-guiding spiral groove is provided on the inner side of the flared structure at the top of the cup body, and the flow-guiding spiral groove extends obliquely from the edge of the flared mouth towards the filter layer structure.

[0013] In some possible implementations, the surface of the flow-guiding spiral groove is provided with a hydrophobic material.

[0014] In some possible implementations, the cup body is made of transparent or translucent plastic material; the outer wall of the cup body is also marked with volume scale markings.

[0015] The urine collection cup provided in this application includes a cup body and a filter layer structure horizontally disposed within the cup body. The filter layer structure is composed of multiple layers of filter material with progressively smaller pore sizes stacked from top to bottom. An extendable handle is provided on the side wall of the cup body above the filter layer structure, and the fixing point of the extendable handle is away from the edge of the cup body opening. A dispensing nozzle is provided on the side wall of the cup body below the filter layer structure, and the dispensing nozzle and the extendable handle are located opposite each other on opposite sides of the cup body. In the technical solution of this application, a gradient multi-layer filter layer structure (such as a polyethylene mesh layer with a pore size of 1-2 mm, an electrospun hydrophilic membrane layer with a pore size of 0.1 mm, and a glass fiber filter paper layer with a pore size of 20 μm) is used, which can effectively remove impurities of different sizes from urine samples. This design not only improves filtration efficiency but also ensures the purity of the final collected urine sample, which is beneficial to improving the accuracy and reliability of subsequent test results. By setting an extendable handle and fixing its point away from the edge of the cup body opening, the risk of urine splashing during collection is significantly reduced, thereby improving the user's sense of security and operating experience.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] As described in the background section, urine sample collection and processing are fundamental and crucial steps in clinical diagnosis and medical research. However, the design of urine collection cups, an indispensable tool in this process, often fails to fully meet the needs of practical use. Currently available urine collection cups generally suffer from insufficient handle length, leading to accidental splashing of urine onto the user's hands during sample collection. This not only inconveniences patients but may also affect the operational experience and hygiene safety of medical staff. Furthermore, existing urine collection cups typically lack a filtration design or an effective filtration mechanism. For example, the prior patent CN205749024U, "Adsorption Filtration Type Random Urine Specimen Collector," uses only a single-layer filter structure made of materials such as sponge, which cannot effectively remove impurities from the urine sample, such as filtering only larger impurities. In certain urine testing scenarios, this may adversely affect subsequent sample analysis, reducing the accuracy and reliability of the test results.

[0022] Based on this, this application proposes a urine collection cup that adopts a multi-layered filter structure with gradient settings to improve the shortcomings of existing related products and meet the needs of real-world scenarios.

[0023] In one embodiment, such as Figure 1 and Figure 2 As shown, the urine collection cup proposed in this application includes a cup body 10 and a filter layer structure 20 horizontally disposed within the cup body 10; the filter layer structure 20 is composed of multiple layers of filter materials with progressively smaller pore sizes stacked from top to bottom.

[0024] Specifically, in some embodiments, the filter layer structure 20 includes, from top to bottom, a polyethylene mesh layer with a pore size of 1-2 mm, an electrospun hydrophilic membrane layer with a pore size of 0.1 mm, and a glass fiber filter paper layer with a pore size of 20 μm. In this embodiment, a polyethylene mesh layer with a pore size of 1-2 mm can intercept large particulate impurities, an electrospun hydrophilic membrane layer with a pore size of 0.1 mm is used to adsorb proteins and cell debris, and a glass fiber filter paper layer with a pore size of 20 μm is used to block microorganisms. The three work together to achieve pre-filtration of the sample during urine collection based on the gravity effect.

[0025] like Figure 1 and Figure 2 As shown, an extendable handle 30 is provided on the side wall of the cup above the filter layer structure 20, and the fixing point of the extendable handle 30 is far away from the edge of the cup opening; a liquid outlet 40 is provided on the side wall of the cup below the filter layer structure 20, and the liquid outlet 40 and the extendable handle 30 are located opposite each other on both sides of the cup.

[0026] It should be noted that in the design of existing urine collection cups, the handle is usually placed close to the rim of the cup to shorten the lever arm. However, this application takes into account the setting of the filter layer structure in the cup body. In order to reduce urine splashing caused by hand vibration, the fixed position of the handle is adjusted, which optimizes the torque and reduces the risk of urine splashing during urine sampling while ensuring the pre-filtration function.

[0027] Furthermore, this implementation method, which uses the nozzle and handle to be positioned opposite each other, allows the wrist to rotate naturally by 45° during subsequent pouring, which conforms to ergonomic principles and avoids the need for wrist twisting during operation, thus improving the user experience.

[0028] The technical solution of this application employs a multi-layered filter structure with gradient settings. Compared to the single-layer filter structure using materials such as sponge in existing technologies, this effectively removes impurities of different sizes from urine samples. This design not only improves filtration efficiency but also ensures the purity of the final collected urine sample, which is beneficial for improving the accuracy and reliability of subsequent test results. For example, a single-layer sponge filter structure cannot solve the problem of coexistence contamination between cell debris (10-50μm) and bacteria (0.5-5μm). This application avoids this problem by achieving synergistic filtration through a pore size gradient design. By setting an extendable handle and fixing its point away from the edge of the cup opening, the risk of urine splashing during collection is significantly reduced, thereby improving the user's sense of security and operating experience.

[0029] On the other hand, the filtration using the above-mentioned filter layer structure is achieved during the process of collecting urine by the patient. In actual scenarios, this time cannot be too long to avoid affecting the patient's experience. Therefore, the filtration performance of the filter layer structure cannot be too strong to avoid affecting the permeability. However, in practice, the demand for subsequent experimental testing may be high, and the above-mentioned filter layer structure alone cannot meet the testing requirements. If the urine sample pre-filtered by the filter layer structure is directly exported and then filtered by an external filter, the operation is cumbersome and the overall cost is high.

[0030] Based on this, considering that the process of collecting urine and the subsequent testing are different stages in the overall process and do not interfere with each other, the inventors have further optimized the structure of the urine collection cup product proposed in the above embodiments, such as... Figure 3 As shown, the liquid storage nozzle 40 is tilted relative to the side wall of the cup body, such as tilted upwards at 25 degrees. The liquid outlet pipe of the liquid outlet nozzle 40 is embedded with a nylon final filter membrane A with a pore size of 5μm. This nylon final filter membrane is used to achieve final filtration when urine is poured out, thus meeting the higher filtration requirements in practice.

[0031] The urine collection cup in this application achieves a dual filtration mechanism through its structural design. The initial filtration utilizes a multi-layered filter structure to remove most larger impurities, while the final filtration is completed by a 5μm nylon final filter membrane integrated into the dispensing nozzle. This design ensures both rapid permeation during the initial filtration process and the purity of the final sample, meeting the requirements of high-standard experimental testing. Furthermore, due to the built-in final filter design, users do not need to transfer the initially filtered sample to other filtering devices for re-filtration, simplifying the operation process, improving work efficiency, and reducing the risk of contamination from multiple operations. The angled dispensing nozzle makes urine pouring out more convenient, facilitating smooth final filtration. This integrated design achieves high-efficiency filtration while reducing the need for additional filtration equipment, thereby lowering overall costs and facilitating large-scale production and widespread use.

[0032] Furthermore, such as Figure 3 As shown, in some embodiments, to ensure that the sample is not secondary contaminated during use, in addition to the final filter membrane, a disposable heat-sealed plastic film 41 is also provided at the end of the dispensing nozzle 40. The disposable heat-sealed plastic film 41 provides a physical barrier to prevent external contaminants from contacting the final filter membrane before final filtration. In practical applications, when performing final filtration, the user only needs to remove the heat-sealed plastic film 41 to perform the final filtration operation of the sample. On the other hand, the disposable heat-sealed plastic film can also prevent the urine collection cup from being improperly reused, avoiding related problems caused by repeated misuse.

[0033] Regarding the extendable handle in this application, the applicant would like to clarify that it can be implemented using various structural methods, such as folding, stretching, and snap-fit.

[0034] However, based on considerations of functionality and cost, in some embodiments, such as Figure 4 As shown, the extendable handle 30 includes: a main rod 31 fixed to the side wall of the cup body; a folding rod 34 hinged to the main rod 31 via a pivot 33; and a semi-circular baffle 32 disposed at the end of the main rod 31, the baffle 32 being integrally formed with the main rod 31.

[0035] That is, combination Figure 4 As shown, this embodiment uses a folding structure to achieve an extendable handle. The extendable handle 30 includes a main rod 31, a baffle 32, a pivot 33, and a folding rod 34. One end of the main rod 31 is fixedly connected to the side wall of the cup body, and the pivot 33 is connected to the other end of the main rod 31 near the end. The folding rod 34 is connected to the main rod 31 through the pivot 33, and the structural dimensions of the folding rod 34 and the main rod 31 are matched. The baffle 32 is a semi-circular plate structure, and the baffle 32 is fixedly connected to the end of the other end of the main rod 31. The baffle 32 and the main rod 31 are integrally formed.

[0036] In practical application, the folding rod in the extendable handle is first folded out from the bottom of the main rod via a pivot. The baffle ensures the position of the folding rod and increases the overall length of the handle. The user holds the folding rod and the baffle (to ensure the overall stability of the handle), and then places the urine cup below the urethra to collect urine. Due to the increased length of the handle, combined with the optimization of the handle fixing point position mentioned above, it helps to avoid urine splashing onto the hands during urine collection.

[0037] Furthermore, in some embodiments, the extendable handle 30 is made entirely of plastic material, such as ABS plastic, with a non-slip texture on the surface to improve ease of use.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the upper part of the cup body 10 is flared to further prevent urine from splashing out.

[0039] Furthermore, as a preferred option, to ensure the effectiveness of the initial filtration, a flow-guiding spiral groove (not shown in the figure) is also provided on the inner side of the trumpet-shaped structure at the top of the cup body 10. The flow-guiding spiral groove extends obliquely from the edge of the trumpet towards the filter layer structure 20. This design of the flow-guiding spiral groove can guide the urine to flow along a predetermined path, slow down its falling speed, and make the liquid more evenly distributed on the entire filtration area, which is conducive to improving the overall collection and filtration efficiency.

[0040] Furthermore, to avoid urine residue, the surface of the flow-guiding spiral groove is also provided with a hydrophobic material. The application of the hydrophobic material can significantly reduce the adhesion of urine in the flow-guiding spiral groove, making the liquid easier to flow and less likely to stay on the groove wall, thereby reducing urine residue.

[0041] Based on the embodiments described above, in some embodiments, the cup body 10 is made of transparent or translucent plastic material so that the user can observe the actual amount of urine collected; the outer wall of the cup body 10 is also provided with volume scale markings to indicate the amount of urine required in some scenarios, making it convenient for the user to use.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
