Urine detection electrochemical sensor and preparation method thereof, and paper diaper

Abstract

The invention provides a urine detection electrochemical sensor and a preparation method thereof, and a paper diaper. The urine detection electrochemical sensor comprises a substrate layer, a reactionlayer and a covering layer, and the substrate layer is used for supporting the reaction layer and the covering layer; wherein the reaction layer sequentially comprises a sample injection unit, an isolation unit and an electrode unit, the sample injection unit is used for enriching urine and transmitting the urine to the electrode unit through a first opening in the isolation unit, and a reactionmaterial is fixed on the electrode unit and used for detecting one or more metabolites in the urine; the covering layer is used for wrapping the substrate layer and the reaction layer and transferringurine to the sample injection unit through a second opening in the covering layer; and the concentration of substances in urine of disabled people (especially disabled old people) is converted into an electric signal to achieve qualitative or quantitative detection of the urine, and therefore, the accuracy of a detection result is improved, the detection cost is reduced, and the problem that urine detection of the disabled people is difficult is solved.

Description

technical field [0001] The disclosure relates to the technical field of medical diagnostic devices, in particular to a urine detection electrochemical sensor, a diaper and a preparation method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] For the elderly, paralyzed or semi-paralyzed patients who need long-term care, it is very inconvenient to use the traditional hospital urine test. For them, in many cases, they cannot consciously urinate, and they are often inconvenient and difficult to take urine, and cannot achieve efficient urine extraction and urine testing. Urine is an important sample commonly used in medical treatment. The protein, inorganic salts, electrolytes and other components in urine play a vital role in clinical diagnosis and efficacy judgment. Unlike blood tests, urine tests have the advantage of being non-invasive ...

Problems solved by technology

Due to the long focal length of some cameras, they cannot focus on the closer color blocks, which has also become a major drawback restricting this method.

Similarly, if the amount of contact between the urine and the test paper cannot be controlled, the test paper will be soaked in the urine for a long time due to the large amount of urination of the wearer, which will cause the color of each reaction area of ​​the test paper to be unstable, resulting in inaccurate test results and a large question
