Embodiment 1

[0037] Detection devices such as figure 1Shown: detection device 8 comprises test strip 1, test strip length 6cm, wide 1cm, color recognition detector 5, LCD display 7, is provided with groove 2 on test strip 1, groove diameter 0.5-0.8cm, preferably 0.7 cm, the color recognition detector 5 is provided with a detection window 4, the test window 4 is located directly above the groove 2, and an LED light 3 is arranged inside the detection device, and the color recognition detector 5 is connected with the LCD display 7 through a data transmission line, and the detection device 8 is also provided with a bluetooth device 6 connected with the color recognition detector 5 through a data connection line.

[0038] Among them, the LED lamp 3, the color recognition detector 5, the bluetooth device 6, and the LED display 7 are all commercial products, and the color recognition detector 5 is TCS3200.

[0039] When in use, put the detection test paper soaked in saliva and urine into the gro...

Embodiment 2

[0042] (1) First prepare the mixed aqueous solution A of sodium citrate and copper sulfate, and at the same time prepare the mixed aqueous solution B of dipotassium cinchoninic acid salt and sodium chloride, and then mix the two mixed aqueous solutions at a volume ratio of 1:0,5 to obtain the reaction Reagent;

[0043] Wherein, in the mixed aqueous solution A, the molar concentration of sodium citrate is 20 mM, and the volume mass concentration of copper sulfate is 0.1% (g / mL). In the mixed aqueous solution B, the volume mass concentration of dipotassium cinchoninate is 2% (g / mL), and the molar concentration of sodium chloride is 10 mM.

[0044] Then soak the filter paper in the reaction reagent for 5 seconds, take it out, bake it at 85° C. for 10 minutes, and dry it with a moisture content of 8%, to obtain a test paper for use.

[0045] (2) Use micro-tweezers to extract a piece of test paper, which is circular. Soak the detection test paper piece in the saliva to be tested ...

Embodiment 3

[0047] The detection test paper was obtained according to the method of Example 2, and a piece of detection test paper was extracted with micro-tweezers, and the test paper sheet was circular. Soak the detection test paper piece in the urine sample #1 to be tested for 5 seconds, put it in the detection groove on the test paper strip for one minute, and after the color of the test paper does not change, use the detection device in Example 1 for detection, 4 minutes Get test results.

Abstract

The invention relates to the technical field of medical detection methods, and provides a uric acid detection method and a uric acid detection device in order to meet requirements of a gout patient for rapid diagnosis and disease monitoring, especially for household rapid disease detection and monitoring. A test sample reacts with detection test paper till that color of the detection test paper ischanged; and an optical signal is converted into a digital signal, and an obtained detection result is stored and displayed. The test method and device can be used to rapidly and simply determine a uric acid index, and help a patient to track and detect an illness state anytime and anywhere.

Description

technical field [0001] The invention relates to the technical field of medical detection methods, in particular to a method for detecting uric acid and a detection device thereof. Background technique [0002] Due to changes in the diet structure of the public, high protein intake, increased protein and purine biosynthesis and metabolism in the body, excessive uric acid production or poor excretion of uric acid can lead to elevated uric acid in the blood, thus forming uric acidemia. Urate crystals are deposited in the joint synovium, bursa and cartilage tissue, causing recurrent inflammatory disease, namely gout. Studies have shown that hyperuricemia is also closely related to the occurrence of urinary stones. The number of patients with hyperuricemia in my country has reached 170 million, of which more than 80 million patients with gout, and is increasing rapidly at an annual growth rate of 9.7%. The incidence of hyperuricemia increased from 10.10% in 1998 to 17.90% in 20...
