Implantation type detection device on the basis of fluorescence detection method

Abstract

The invention provides an implantation type detection device on the basis of a fluorescence detection method, and relates to detection of a specific compound in subcutaneous tissue. The device comprises a sensing head, a signal generating / detecting device and a signal receiving / detecting device; the sensing head is implanted in the human body and exposed in subcutaneous interstitial fluid, and senses the concentration of molecules to be detected; the sensing head is connected with the signal generating / detecting device through an optical fiber, and the signal generating / detecting device and the signal receiving / detecting device conduct data transmission in a wire or wireless mode; exciting light and signal fluorescence generated in the signal generating / detecting device are transmitted through the same optical fiber, and received through the signal receiving / detecting device, light intensity of the signal fluorescence is detected, and therefore the concentration of the quantitative compound is obtained. Application of electrochemistry and enzymes is avoided by adopting an optical measuring method, durability is good, sensitivity is high, and service life is long.

Description

technical field [0001] The implantable detection device based on the fluorescence detection method of the present invention relates to the detection of a specific compound in the subcutaneous tissue, and is a detection device based on the fluorescence detection method. Background technique [0002] In the daily care of the medical industry, the continuous detection of a specific compound in the body is often required. For example, diabetes is the second killer of modern diseases, and its harm to the human body is second only to cancer. As a relatively common endocrine disease, it is more and more harmful to people's physical and mental health, and it has the tendency to expand and rejuvenate. the trend of. The research results show that: the main feature of diabetes is the slowly and continuously rising blood sugar concentration. When the blood sugar concentration rises to a certain height, the sugar can be detected in the urine when it is higher than the renal glucose thre...

Problems solved by technology

Drawbacks of these sensors include: 1. Their electrochemical selectivity is limited

Therefore, the use of electrochemical-based glucose measurement in seriously ill patients is very dangerous

2. There is a considerable drift current in the sensor, which invalidates the reading

3. Due to the use of enzymes and proteins, the life of the sensor is extremely limited

At present, in China, there is no enterprise company that has successfully researched
