Description

A portable urine analysis device for kidney disease patients Technical Field

[0001] This utility model relates to the field of urine analysis technology, and more specifically, to a portable urine analysis device for patients with kidney disease. Background Technology

[0002] Portable urine analyzers for kidney disease patients are medical devices specifically designed to help monitor and manage kidney health. These devices typically detect multiple components in urine, such as protein, glucose, ketones, red blood cells (or hemoglobin), white blood cells, nitrates, urobilinogen, specific gravity, and pH. These are important indicators for assessing kidney function. These devices are designed to be small and lightweight enough for patients to use at home or on the go. Most portable urine analyzer strips provide results within minutes, improving efficiency. This type of device is particularly suitable for patients with chronic kidney disease, diabetes, and anyone who needs to regularly monitor changes in their urine composition. It can help detect potential problems early and encourage patients to be more proactive in managing their health.

[0003] Chinese Patent Publication No. CN213398192U discloses a portable urine analysis device. The device has a circuit board inside its outer casing. A power supply is fixedly mounted at the bottom of one end of the circuit board, and a display screen is connected above it. A urine testing device is mounted above the other end of the circuit board. This device includes a rectangular groove and a reflector mounted above it, forming a dark chamber. The upper surface of the rectangular groove has openings at both ends. The outer casing has a collection port and a drainage port corresponding to the openings at both ends. Several sets of light source receiving sensors are electrically connected to the bottom of the rectangular groove via the circuit board. This invention is compact and portable, can be rinsed and reused repeatedly, requires no consumables, and allows the emitted light from the detection light source to be received by the receiver after multiple reflections through the reflective parts in the dark chamber, thus obtaining an attenuated light intensity signal, which is then converted into an electrical signal. By increasing reflection, the volume of the chamber can be reduced, thereby reducing the volume of the sample required for testing; only a small amount of sample is needed to obtain results.

[0004] In practical use, existing technologies are prone to leakage due to users adding too much urine or making excessive movements when inserting or removing test strips during sampling or testing, causing contamination of the user's hands or other surfaces and increasing hygiene risks. Therefore, a portable urine analysis device for kidney disease patients is proposed. Summary of the Invention

It uses two rubber pads inside the fixing base to hold and fix the test strip, which is then removed as the tube cap moves, eliminating the need to manually remove the test strip. The transparent window allows direct observation of the color change of the test strip, and the results can be read without removing the test strip. The sealing plug at the connection between the test tube and the tube cap is tightly closed, preventing moisture in the air from entering and causing the test strip to deteriorate before testing, and also preventing leakage of urine and odor during testing.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A portable urine analysis device for patients with kidney disease includes a test tube with a cap installed at the upper end.
