Problems solved by technology

Hospitals mostly use urine ten-item automatic biochemical analyzers to measure urine sugar, which is expensive, and urine sugar test strips are also used
At present, there is no urine glucose meter that can be used by patients with diabetes and kidney disease at home. Patients with chronic diseases such as kidney disease and diabetes need to go to the hospital for examination repeatedly, which is neither economical nor convenient.

Embodiment Construction

[0023] In order to better understand the technical solution of the present invention, a further detailed description will be made below in conjunction with the accompanying drawings.

[0024] The schematic diagram of the optical path of the portable human urine sugar tester of the present invention is as follows: figure 1 As shown, the light emitting diode 1, the collimating lens (or mirror group) 2, the cuvette or colorimetric tube in the sample chamber 3, the converging lens (or mirror group) 4, the optical filter 5, and the photodiode 6 are arranged in sequence On the same optical axis, the light emitted by the light-emitting diode 1 is collimated by the collimator lens 2 into approximately parallel light, and the parallel light enters the sample chamber 3, and vertically illuminates the sample to be tested contained in the cuvette or cuvette, and the transmitted light After being converged by the converging lens 4 and filtered by the filter 5, the light is received by the ...

Abstract

The related portable human tester for glucose in urine comprises: an optical path with a LED, a collimation lens, a focus lens, an optical filter and a photoelectric diode; and an electric signal processing circuit with a V / A converter, an amplifier, a SCM with ADC, a display screen, some keys and interfaces, the cell, and the LED drive circuit, wherein it arranges the optical path on the circular channel of sample pond with central cavity for sample and side room for reeds or spring balls, and the signal processing circuit also includes clock set, timing detection prompt, curve display and printing. This invention can be used by both user in home and doctor in hospital.

Description

technical field [0001] The invention relates to a portable human urine sugar tester, which is used for measuring human urine sugar, providing diagnosis basis for patients or monitoring the course of disease, and belongs to the technical field of biochemical and clinical medical testing. Background technique [0002] Urine glucose examination is a very important diagnostic basis for urinary system diseases, and also has very important reference value for the diagnosis of certain systemic diseases such as diabetes, blood diseases, liver and gallbladder diseases, and epidemic hemorrhagic fever. At the same time, dynamic monitoring of urine sugar can also reflect the therapeutic effect and prognosis of some diseases. Especially for patients with chronic diseases such as diabetes, it is necessary to monitor their blood sugar and urine sugar frequently and repeatedly for a long time, and to understand their changes, in order to provide a basis for diagnosis and monitor the progres...
