Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a urine collection device for quantitative detection of urine protein. Background Technology

[0002] Normal human urine contains trace amounts of protein, with daily excretion below 150 mg, primarily albumin, with varying amounts of globulin and other proteins depending on the specific disease. With the advancement of nephrology research, observing the daily protein excretion of patients to indicate changes in their condition has become crucial. Therefore, urinary protein quantification has practical clinical value and has become a routine test in hospital laboratories.

[0003] Currently, existing urine storage devices for quantitative urine protein testing are poorly designed, mostly using ordinary wide-mouth containers lacking leak-proof features. Spillage is common during urine transfer, leading to sample loss and environmental contamination. Patients need to pour urine into a main container at different times, increasing the probability of microbial contamination due to repeated opening and closing. The lack of clear time markings makes it difficult to intuitively judge the collection progress, requiring repeated measurements of urine volume and calculation of the total volume, increasing operational complexity. The lack of a temperature control system makes it difficult to maintain the required 4-8℃ refrigeration temperature in a home environment, leading to protein decomposition and affecting detection accuracy. Furthermore, the lack of a corresponding slow-release preservative function easily causes urine deterioration. Therefore, a urine collection device for quantitative urine protein testing is needed to solve these problems. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a urine collection device for quantitative detection of urine protein, featuring a leak-proof filter design to prevent impurities from entering; precise scale markings for easy monitoring of urine volume; and cooling and anti-corrosion functions to ensure urine quality.

A first threaded tube is fixed to the center of the top surface of the reservoir, and the first threaded tube communicates with the inner side of the reservoir. A liquid-guiding funnel is threadedly connected to the outer side of the first threaded tube. A second threaded tube is fixed to the lower end of the liquid-guiding funnel, and the second threaded tube is threadedly connected to the outer side of the first threaded tube. A first filter screen is fixed to the inner wall of the upper end of the liquid-guiding funnel, and a second filter screen is fixed to the inner wall of the liquid-guiding funnel, with the second filter screen located below the first filter screen. An anti-backflow valve is fixed to the inner wall of the liquid-guiding funnel, with the anti-backflow valve located below the second filter screen. An external thread is fixed to the outer wall of the upper end of the liquid-guiding funnel, and a threaded cap is threadedly connected to the outer side of the upper end of the liquid-guiding funnel. A warning line is provided on the outer wall of the upper end of the reservoir. A first graduation groove is provided on the outer wall of the reservoir, with the first graduation groove located below the warning line. A second graduation groove is provided on the outer wall of the reservoir, with the second graduation groove located below the first graduation groove.

[0006] As a preferred technical solution of the urine collection device for quantitative detection of urine protein of the present invention, an annular preservative is fixed in the middle of the bottom surface of the inner side of the storage container, and an annular soluble film is sleeved on the outer side of the annular preservative, and the annular soluble film is fixed on the bottom surface of the inner side of the storage container.

[0007] As a preferred technical solution of the urine collection device for quantitative detection of urine protein of this utility model, the bottom surface of the storage container is fixed with a base, the bottom surface of the base is provided with an anti-slip groove, and the inner side of the upper end of the base is provided with a receiving groove.

[0008] As a preferred technical solution of the urine collection device for quantitative detection of urine protein of this utility model, a cooling plate is fixed on the bottom surface of the storage container, the cooling plate is located inside the receiving groove, a cooling column is symmetrically fixed on the top surface of the cooling plate, the upper end of the cooling column is located inside the storage container, and a thermometer is fixed in the middle of the bottom surface inside the storage container.

[0009] As a preferred technical solution of the urine collection device for quantitative detection of urine protein of this utility model, a fixing ring is fixed on the inner wall of the lower end of the liquid guiding funnel. The fixing ring is located below the anti-backflow valve. A sealing ring is fixed on the top end of the first threaded tube. The sealing ring is tightly fitted with the bottom surface of the fixing ring.

[0010] As a preferred technical solution of the urine collection device for quantitative detection of urine protein according to this utility model, a sealing plate is fixed on the inner top surface of the threaded cap, and the sealing plate is tightly fitted to the upper end of the liquid funnel.

[0011] As a preferred technical solution of the urine collection device for quantitative detection of urine protein according to this utility model, the second filter screen has a smaller pore size than the first filter screen, and both the second filter screen and the anti-backflow valve are made of silicone.

[0012] As a preferred technical solution of the urine collection device for quantitative detection of urine protein of this utility model, the anti-slip groove is provided in multiple ways, the storage container is made of transparent material, and the sealing ring and sealing plate are both made of elastic material.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model's fluid-guiding funnel connects to the first threaded tube on the top surface of the reservoir via a second threaded tube, making disassembly simple and facilitating urine pouring. The sealing ring and fixing ring fit tightly to prevent urine leakage. Patients can urinate directly through the funnel without needing to pour urine into the reservoir after urination. The first filter screen prevents external impurities from entering the reservoir, improving urine purity. The second filter screen is made of silicone; when urine passes through the second filter screen, foam breaks and is removed. The silicone anti-backflow valve opens under the impact of urine, allowing urine to enter the reservoir, and closes after entry to prevent backflow. By rotating the threaded cap onto the outside of the funnel and ensuring a tight seal between the sealing plate and the funnel, urine leakage or odor seepage during transport is prevented. This filtration and leak-proof design allows for direct use by patients, eliminating the need for a separate container to urinate and then pour urine into the reservoir, thus improving convenience. The detachable funnel facilitates urine pouring and is safe to carry, eliminating concerns about spillage or odor seepage.

[0014] This invention features a warning line, a first scale groove, and a second scale groove on the outer wall of a transparent storage container. The warning line is the maximum capacity line, which can indicate to the patient that the capacity has reached its maximum value. The first scale groove is a large-scale total scale area, and the second scale groove is a fine scale area at the bottom, which meets the patient's need to accurately read the capacity when storing a large amount or a small amount of urine.

[0015] This invention monitors the internal temperature using a thermometer inside the storage container. Cooling is achieved through a cooling element and conduction via a cooling column, maintaining a consistently low temperature inside the container to prevent urine deterioration and protein decomposition from affecting detection accuracy. Furthermore, an annular preservative is located inside the storage container, surrounded by an annular soluble film. When urine comes into contact with this film, it melts, allowing the preservative to dissolve into the urine, further preventing deterioration and maintaining the quality of the urine being tested.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-5 As shown, the present invention provides the following technical solution: a urine collection device for quantitative detection of urine protein, including a storage container 1, a base 3 fixed on the bottom surface of the storage container 1, and an anti-slip groove 31 provided on the bottom surface of the base 3. Multiple anti-slip grooves 31 are provided. The base 3 provides stable support for the storage container 1. The anti-slip grooves 31 can enhance friction, prevent the base 3 from sliding, and enhance stability.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, specifically, a first threaded tube 15 is fixed to the center of the top surface of the reservoir 1 for connecting and fixing a second threaded tube 21. The first threaded tube 15 is connected to the inner side of the reservoir 1. A liquid-guiding funnel 2 is threadedly connected to the outer side of the first threaded tube 15 for receiving and guiding urine. The lower end of the liquid-guiding funnel 2 is fixed with the second threaded tube 21 for installing and fixing the liquid-guiding funnel 2. The second threaded tube 21 is threaded to the outer side of the first threaded tube 15. A first filter screen 23 with a larger aperture is fixed to the inner wall of the upper end of the liquid-guiding funnel 2 to filter impurities in the urine or from the outside. A second filter screen 24 with a smaller aperture is fixed to the inner wall of the liquid-guiding funnel 2 to help... To help break up foam in urine, a second filter 24 is located below the first filter 23. The pore size of the second filter 24 is smaller than that of the first filter 23. An anti-backflow valve 25 is fixed to the inner wall of the funnel 2, with a notch in the middle. Normally, it closes automatically due to the elasticity of the silicone, but opens when impacted by urine to prevent backflow. The anti-backflow valve 25 is located below the second filter 24. Both the second filter 24 and the anti-backflow valve 25 are made of silicone. A fixing ring 26 is fixed to the inner wall of the lower end of the funnel 2 to prevent urine from leaking from the gap between the first threaded tube 15 and the second threaded tube 21. The fixing ring 26 is located below the anti-backflow valve 25. Below, a sealing ring 151 is fixed to the top of the first threaded tube 15. The sealing ring 151 fits tightly against the bottom surface of the fixing ring 26 to enhance the sealing and prevent urine from leaking from the gap between the first threaded tube 15 and the second threaded tube 21. An external thread 27 is fixed to the outer wall of the upper end of the liquid guiding funnel 2 for threaded connection of the threaded cap 22. The threaded cap 22 is threadedly connected to the outer side of the upper end of the liquid guiding funnel 2 to seal the liquid guiding funnel 2. A sealing plate 221 is fixed to the top surface of the inner side of the threaded cap 22 to enhance the sealing and prevent urine leakage. The sealing plate 221 fits tightly against the upper end of the liquid guiding funnel 2. Both the sealing ring 151 and the sealing plate 221 are made of elastic material. The solution uses a first filter 23 to filter impurities, a second filter 24 to break up foam in urine, and an anti-backflow valve 25 to prevent backflow, allowing patients to urinate directly inside the drainage funnel 2 without needing a separate container to pour the urine into the storage container 1, thus improving convenience. After the threaded cap 22 is placed on the drainage funnel 2, the sealing plate 221 seals the drainage funnel 2, and the sealing ring 151 and the bottom surface of the fixing ring 26 fit tightly together to effectively prevent urine or odor from escaping during transport. Furthermore, the drainage funnel 2 can be disassembled, making it convenient to pour the urine into the storage container 1, which is beneficial for doctors' testing work. Example 2

[0022] In another embodiment of this solution, refer to Figure 1As shown, specifically, the storage container 1 is made of transparent material. A warning line 11 is provided on the upper outer wall of the storage container 1 to indicate its maximum capacity. A first graduation groove 12 is provided on the outer wall of the storage container 1 for reading the capacity when there is a large amount of urine. The first graduation groove 12 is located below the warning line 11. A second graduation groove 13 is provided on the outer wall of the storage container 1 to provide an accurate reading when there is a small amount of urine. The second graduation groove 13 is located below the first graduation groove 12. This design, through the setting of the first graduation groove 12 and the second graduation groove 13, ensures that the capacity can be observed regardless of the amount of urine, making it convenient for patients to monitor their urine volume. Furthermore, the warning line 11 reminds patients to pay attention to the urine volume and avoid excessive urine output. Example 3

[0023] In another embodiment of this solution, refer to Figure 2 and Figure 5 As shown, specifically, an annular preservative 17 is fixed in the middle of the inner bottom surface of the storage container 1 (the annular preservative 17 is existing technology; its specific operation and principle can be referred to in the existing technology of urine sample preservatives, which are used to prevent the growth of microorganisms in urine and thus prevent deterioration; therefore, it is not described in detail here). An annular soluble membrane 18 is sleeved on the outside of the annular preservative 17 (the annular soluble membrane 18 is existing technology; its specific operation and principle can be referred to in the existing technology of water-soluble membranes, which melt when in contact with water in urine; therefore, it is not described in detail here). The annular soluble membrane 18 is fixed on the inner bottom surface of the storage container 1. In this scheme, when urine enters the storage container 1 and comes into contact with the annular soluble membrane 18, the annular soluble membrane 18 melts, allowing the annular preservative 17 to come into contact with the urine and dissolve into the urine, thus preventing urine deterioration and protein decomposition from affecting the accuracy of detection. Example 4

[0024] In another embodiment of this solution, refer to Figure 2 and Figure 5As shown, specifically, the upper inner side of the base 3 is provided with a receiving groove 32 to provide space for the cooling chip 14. The cooling chip 14 is fixed on the bottom surface of the storage unit 1 (the cooling chip 14 is existing technology; its specific operation and principle can be referred to in the prior art semiconductor cooling chip, which is controlled by an external power supply, so it is not described in detail here). The cooling chip 14 is located inside the receiving groove 32. A cooling column 141 is symmetrically fixed on the top surface of the cooling chip 14 to conduct the low temperature generated by the cooling chip 14. The upper end of the cooling column 141 is located inside the storage unit 1. A thermometer 16 is fixed in the middle of the bottom surface inside the storage unit 1 (the thermometer 16 is existing technology; its specific operation and principle can be referred to in the prior art temperature sensor, which can monitor the temperature, so it is not described in detail here). In this solution, the cooling chip 14 cools the urine, and the cooling column 141 conducts the low temperature to the inside of the storage unit 1, keeping the urine at a low temperature, preventing the protein from decomposing due to excessively high temperature, affecting the accuracy of the test, and improving the quality of the urine to be tested.

[0025] The working principle and usage process of this utility model: When in use, the patient can directly urinate into the inner side of the drainage funnel 2. The urine passes through the first filter screen 23 to filter out any impurities that may be present in the urine or from the outside environment, and then falls onto the second filter screen 24. The second filter screen 24 has a smaller pore size, which can better break up and remove foam in the urine. Then, the urine falls through the second filter screen 24 onto the silicone anti-backflow valve 25 below. The impact force opens the notch on the anti-backflow valve 25, and the urine enters the reservoir 1 through the notch. After the urine passes through, the notch automatically closes due to the elasticity of the silicone to prevent urine backflow. After the urine enters the reservoir 1, it melts the annular soluble membrane 18, allowing the annular preservative 17 to come into contact with the urine and dissolve into the urine for preservation. The thermometer 16 can continuously monitor the urine temperature. The cooling element 14 is energized and cools the urine. Through the conduction of the cooling column 141, the urine is kept at a low temperature to prevent it from deteriorating. Rotate the threaded cap 22 onto the liquid funnel 2, and after the sealing plate 221 is tightly fitted to the upper end of the liquid funnel 2, the liquid funnel 2 can be sealed. The sealing ring 151 and the fixing ring 26 are tightly fitted to seal the inside of the storage container 1, which can ensure that the urine will not leak and the odor will not be emitted, making it convenient to carry the urine to the testing location for testing. After rotating the second threaded tube 21 to separate it from the first threaded tube 15, the liquid funnel 2 can be disassembled, making it convenient to pour out the urine inside the storage container 1 for testing.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
