Embodiment Construction

[0047] The specific embodiments and working principles of the present invention will be described in further detail below with reference to the accompanying drawings.

[0048] Such as figure 1 As shown, a urine analysis device based on color RGB components includes a processor 1 and a serial communication unit 3, a temperature measurement unit 4, a light intensity control unit 5, and a color sensor unit 8 connected to the processor 1. The device 1 controls the luminous intensity of the white LED lamp 6 through the light intensity control unit 5. The light emitted by the white LED lamp 6 illuminates the urine test strip on the sampling platform, and the color sensor unit 8 is used to obtain the reflected light of each reagent area of ​​the urine test strip. For the color RGB component, the processor 1 determines the semi-quantitative value of the detection index corresponding to each reagent area according to the color RGB component and the temperature information acquired by the ...

Abstract

The invention discloses a color RGB (red, green and blue)-component-based urine analysis device, which is characterized by comprising a processor, a serial communication unit, a temperature measuring unit, a light intensity control unit and a color sensor unit, wherein the processor controls the light intensity of a white LED (light-emitting diode) lamp through the light intensity control unit, light emitted from the white LED lamp shines on a urinalysis test strip on a sampling platform, a color RGB component of reflected light of each reagent area of the urinalysis test strip is acquired by using the color sensor unit, and the processor determines a semi-quantitative value of a corresponding detection index of each reagent area according to the color RGB components and temperatures. The device and the method disclosed by the invention have the remarkable effects that the circuit structure is simple, and the cost is low; through the coordination of the color sensor unit and the temperature detection unit, a calculation coefficient of each detection index is fitted by using an experience numerical value of the existing precision instrument, so that a microprocessor can calculate an accurate measurement index by using the coefficients; the device is high in equipment precision and wide in temperature application range.

Description

Technical field [0001] The invention relates to a conventional urine detection technology in the field of biomedicine, in particular to a urine analysis device based on color RGB components and a processing method thereof. Background technique [0002] Urinalysis is one of the most commonly used clinical laboratory indicators. It not only provides references for the diagnosis of urinary system diseases and observation of curative effects, but is also very helpful for the diagnosis and treatment of other system diseases that can cause changes in blood biochemical components. In addition, urinalysis can also be used for safe medication testing and preliminary health status assessment. [0003] As a traditional method, urine test is often based on the color change produced by the reaction between the reagent area on the test strip and the biochemical components in the urine sample, qualitatively or semi-quantitatively detecting urobilinogen, bilirubin, and ketone bodies in the urine s...
