Abstract
Description
Technical Field
[0001] This application relates to the field of urine testing technology, and in particular to a fast and convenient urine testing device. Background Technology
[0002] Urinalysis can detect infection markers such as white blood cells and bacteria, helping to detect and treat infections early. Indicators in urinalysis, such as protein and red blood cells, can reflect kidney function and help identify potential problems promptly. Urinalysis results can provide a basis for antibiotic use and catheter care, optimizing treatment. Indwelling catheters easily lead to urinary tract infections; regular urinalysis helps reduce infections and complications, improving patients' quality of life. Traditional urine testing methods usually require sending samples to a laboratory for analysis, which has the following significant drawbacks: Poor timeliness: Test results take several hours or even longer, which cannot meet the needs of rapid clinical diagnosis; Complex to operate: requires specialized equipment and personnel, and is difficult to implement in non-laboratory environments (such as homes or primary care clinics); High risk of infection: Frequent disconnection of the urinary catheter for sampling may disrupt the sterile environment and increase the probability of urinary tract infection; Limited functionality: Most existing portable testing devices only support the detection of a single indicator, which cannot meet the needs of simultaneous screening of multiple parameters.
[0003] While some integrated urine testing devices exist in the current technology, their complex structure, large size, and lack of aseptic design to accommodate catheter systems make it difficult to achieve rapid and safe bedside or home testing. Therefore, there is an urgent need for a urine testing device that can be seamlessly connected to a catheter, supports rapid testing of multiple indicators, and provides sterility assurance. Summary of the Invention
[0004] To address the aforementioned problems, this application provides a rapid and convenient urine testing device. By controlling the urine flow rate through micro-orifices on the test disc, it achieves simultaneous and rapid detection of multiple indicators, with results available within minutes. The technical solution is as follows: This application provides a fast and convenient urine testing device, including a transparent outer cover, a test disc, a urine output valve, and a sealing assembly. A urine testing inner tube is inserted through the center line of the transparent outer cover, with both ends extending out of the transparent outer cover to connect to a catheter or external device. The test disc is fixedly disposed in the middle of the transparent outer cover, and the urine testing inner tube is vertically inserted into the center of the test disc. Multiple flow guide holes are distributed circumferentially along the outer wall of the urine testing inner tube to guide urine to flow from the outer wall of the inner tube and along the tube wall to the surface of the test disc for testing. Several adjustment holes are provided on the test disc. The urine output valve is located at the bottom of the transparent outer cover to control the flow of urine to a urine bag or sampling port. The sealing assembly is located at the connection between the transparent outer cover and the urine testing inner tube to maintain a sterile environment inside the device.
[0005] For example, in one embodiment of the fast and convenient urine testing device, the diameter of the flow guide hole is 0.2-0.8 mm, and it is arranged in a spiral shape along the outer wall of the urine testing inner tube with a hole spacing of 2-5 mm, which is used to control the urine flow rate and the area covered by the test plate.
[0006] For example, in one embodiment of the rapid and convenient urine testing device, the aperture of the adjustment hole is in the range of 0.1-0.5 mm, the hole spacing is 0.5-2 mm, and they are distributed radially or concentrically.
[0007] For example, in one embodiment of the fast and convenient urine testing device, the transparent outer cover is a cylindrical structure, and its inner wall forms an annular flow channel with the urine testing inner tube to guide the urine to flow evenly to the test plate.
[0008] For example, in one embodiment of the rapid and convenient urine testing device, the sealing assembly includes a silicone sealing ring and a waterproof adhesive layer. The silicone sealing ring is nested at the connection end between the urine testing inner tube and the transparent outer cover, and the waterproof adhesive layer is coated on the mating surface between the test disc and the transparent outer cover.
[0009] For example, in one embodiment of the rapid and convenient urine testing device, the device is integrally injection molded from medical-grade polycarbonate, and the inner tube for urine testing is a medical-grade stainless steel tube.
[0010] The beneficial effects of the fast and convenient urine testing device provided in some embodiments of this application are as follows: (1) Rapid detection: The flow rate of urine is controlled by the micro-hole of the test plate, and multiple indicators can be detected simultaneously. The results can be read within minutes.
[0011] (2) Easy to operate: It can be directly connected to the urinary catheter system without disconnecting the tubing, reducing the risk of infection, and can be operated without professional skills.
[0012] (3) Aseptic design: The combination of sealing components and disposable consumables ensures the asepticity of the testing process and sample collection.
[0013] (4) Portability and compatibility: The miniaturized design is suitable for various scenarios, and the standardized interface is compatible with mainstream catheters. Attached Figure Description

[0018] This application provides a fast and convenient urine testing device, such as... Figure 1-2 As shown, it includes: A transparent outer cover 1 has a urine detection inner tube 2 running through it along its center line. Both ends of the urine detection inner tube 2 extend out of the transparent outer cover 1 to connect to a catheter or external device. The test tray 3 is fixedly installed in the middle of the transparent outer cover 1, and the urine detection inner tube 2 is vertically inserted into the center of the test tray 3; Multiple guide holes 21 are distributed circumferentially along the outer wall of the inner tube 2 for guiding urine to flow out from the outer wall of the inner tube and flow along the tube wall to the surface of the test plate 3 for detection; several adjustment holes 31 are provided on the test plate 3 for controlling the flow rate of urine from the guide holes 21 to the test plate 3, and the urine detection time can be changed by adjusting the number and diameter of the adjustment holes 31. The urine output valve 4 is located at the bottom of the transparent outer cover 1 and is used to control the flow of urine to the urine bag or sampling port; The sealing component 5 is located at the connection between the transparent outer cover 1 and the urine detection inner tube 2 to maintain a sterile environment inside the device.
[0019] According to the above embodiments, by setting a guide hole 21 on the outer wall of the urine detection inner tube 2, the urine is guided to flow out evenly along the tube wall, avoiding direct impact on the test plate 3 and ensuring detection stability; by dynamically adjusting the number and diameter of the adjustment holes 31 on the test plate 3, the urine flow rate is controlled, flexibly adapting to different detection scenarios (such as rapid screening or high-sensitivity detection); through the urine output valve 4, sterile and fresh urine can be conveniently collected, thereby enabling further analysis of the urine.
[0020] For example, in one embodiment of the rapid and convenient urine testing device, such as Figure 1 As shown, the diameter of the guide holes 21 is 0.2-0.8 mm, and they are arranged in a spiral shape along the outer wall of the urine detection inner tube 2, with a hole spacing of 2-5 mm. These holes are used to control the urine flow rate and cover the area of the test plate 3. According to the above embodiment, the spirally distributed small holes guide the urine to flow evenly along the tube wall, optimizing the urine dispersion effect and preventing detection errors caused by local accumulation.
[0021] For example, in one embodiment of the rapid and convenient urine testing device, such as Figure 1-2 As shown, the aperture of the adjustment holes 31 ranges from 0.1 to 0.5 mm, the spacing between holes is 0.5 to 2 mm, and they are distributed radially or concentrically. The contact time between urine and reagents can be prolonged by reducing the number of adjustment holes 31 and / or reducing their aperture, or the detection time can be shortened by increasing their number and / or enlarging their aperture. According to the above embodiments, reducing the number of adjustment holes or reducing their aperture can prolong the reaction time between urine and reagents, improving the detection accuracy of low-concentration indicators; increasing the number of holes or enlarging their aperture can speed up the detection process, meeting emergency needs.
[0022] For example, in one embodiment of the rapid and convenient urine testing device, such as Figure 1 As shown, the transparent outer cover 1 has a cylindrical structure, and its inner wall forms an annular flow channel 11 with the urine detection inner tube 2, which is used to guide the urine to flow evenly to the test plate 3. According to the above embodiment, the annular flow channel 11 further evenly distributes the urine, ensuring complete coverage of the reagent layer 32.
[0023] For example, in one embodiment of the rapid and convenient urine testing device, such as Figure 1As shown, the sealing assembly 5 includes a silicone sealing ring and a waterproof adhesive layer. The silicone sealing ring is nested at the connection end between the urine testing inner tube 2 and the transparent outer cover 1, and the waterproof adhesive layer is applied to the mating surface between the test tray 3 and the transparent outer cover 1. According to the above embodiment, through the dual sealing design—the silicone sealing ring and the waterproof adhesive layer working together—the sterility and leak-proof performance of the device are ensured.
[0024] For example, in one embodiment of the rapid and convenient urine testing device, the device is integrally injection molded from medical-grade polycarbonate, and the urine testing inner tube 2 is a medical-grade stainless steel tube. According to the above embodiments, the urine testing device of this application adopts a miniaturized design, making it convenient for bedside or home use; the medical-grade polycarbonate and stainless steel inner tube ensure biocompatibility and corrosion resistance, and the integral injection molding ensures structural strength.
[0025] This urine testing device can be installed between a urinary catheter and a urine bag during use and can be removed after use. It is used for rapid initial screening of urinary tract infections, with results available within minutes. It is simple to use, requires no complex equipment or professional skills, and is relatively inexpensive, making it suitable for large-scale screening and routine examinations. The device is small, portable, and easy to use on-site. It can simultaneously test multiple indicators, such as pH, glucose, protein, and occult blood, requiring only a small urine sample; it is painless and convenient. It is suitable for various settings including hospitals, clinics, and homes.
[0026] Although the embodiments of this application have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this application. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this application is not limited to the specific details and the illustrations shown and described herein.
