Salivary glucose concentration acquiring device

Abstract

The invention discloses a salivary glucose concentration acquiring device, which is characterized by comprising a sample collecting part, an electrochemical reaction trough and an electric signal transmission conducting wire, wherein the sample collecting part is formed by polyurethane foam and is used for collecting a saliva sample; the electrochemical reaction trough is filled by Flavin adeninedinucleotide complex glucose dehydrogenase and is used for ensuring that the saliva sample collected by the sample collecting part is carried out the electrochemical reaction; the electric signal transmission conducting wire is connected onto the electrochemical reaction trough and is used for conducting the current generated inside the electrochemical reaction trough onto a main machine; and an insulation layer is arranged surrounding the electrochemical reaction trough. The device has the advantages that: through polyurethane adsorption technology, nanoparticles enzyme coating technology and the electrochemical reaction signal capturing and processing technology, the saliva with lower content of glucose becomes an ideal detection sample, so the blood glucose concentration is indirectly measured by measuring the concentration of the salivary glucose on the basis of the positive correlative property between the salivary glucose concentration and the blood glucose concentration. In addition, the device also has the characteristics of simple structure, convenience in production and low cost, and is suitable for being widely popularized.

Description

Technical field [0001] The invention relates to a device for obtaining the concentration of saliva. Background technique [0002] Self-monitoring of blood glucose (SMBG) for diabetic patients is currently an internationally recognized method of diabetes management. The domestic and international blood glucose meter market is huge, and there are various brands of instruments, but the working principles are similar. They all need acupuncture blood to collect more or less whole blood samples (0.3-10 microliters), scientifically and reasonably daily 5- The 6 tests will accumulate nearly 2,000 acupuncture injuries per year. [0003] In recent years, a variety of technologies that can achieve the purpose of non-invasive blood glucose detection have been studied internationally, and some corresponding instruments have come out. But so far, no portable non-invasive blood glucose meter with easy operation, stable measurement and moderate price has been widely recognized by the market. Suc...

Problems solved by technology

The problem with this method is that the blood glucose characteristic spectrum signal is often weak and difficult to measure; this signal is related to body temperature and body fluid composition and must be corrected

PENDRA, GLUCOBAND and other related instruments have appeared abroad, but they have faded out of the market due to their high price and low accuracy.

There are also some instruments based on body temperature detection method, nuclear magnetic resonance method, subcutaneous electrode implantation method, Lehman ray method, etc., but they are all immature
