Embedded porphyrin sensor array-based saliva sugar and urine sugar detector

Abstract

The invention discloses an embedded porphyrin sensor array-based saliva sugar and urine sugar detector. The detector comprises a porphyrin sensor array, an image acquisition instrument, an illumination device and an embedded processing controller, wherein the image acquisition instrument and the illumination device are connected with the embedded processing controller respectively; the porphyrin sensor array comprises an organic glass plate and porphyrin units; a plurality of porphyrin unit installation holes are formed on the organic glass plate; and the porphyrin unit is installed on the top of each porphyrin unit installation hole in a sealed mode. The acquired saliva or urine is input into the porphyrin sensor array, the color images of the porphyrin units subjected to reaction are acquired, the acquired digital images are input into the embedded processing controller by the image acquisition instrument, and the embedded processing controller analyzes the digital images and directly detects the sugar content of the saliva and the urine. Therefore, the detector can provide non-invasive, continuous and direct detection means, and the detected sugar content of the saliva and the urine of persons with diabetes are more accurate.

Description

technical field [0001] The invention relates to a siaglycosuria detection instrument, in particular to a siadialysis glucose detection instrument based on an embedded porphyrin array sensor. Background technique [0002] Diabetes (diabetes) is caused by genetic factors, immune dysfunction, microbial infection and its toxins, free radical toxins, mental factors and other pathogenic factors acting on the body to cause hypofunction of pancreatic islets, insulin resistance (Insulin Resistance, IR), etc. A series of metabolic disorder syndromes caused by sugar, protein, fat, water and electrolytes, clinically characterized by hyperglycemia, typical cases may appear polyuria, polydipsia, polyphagia, weight loss and other manifestations, that is, "three more and one less” symptoms. [0003] In the current global environment where the form of diabetes is deteriorating, the incidence of diabetes in China is also showing a rapid growth trend. At present, China has become the s...

Problems solved by technology

[0006] Due to the influence of the temperature of the working environment, the traditional glucose enzyme test paper is not too accurate, and it is not easy to store, and it is easy to oxidize in the air, resulting in the failure of the test paper; the existing glucose enzyme electrode probe needs to be inserted into the human epidermis. trauma and pain
