Wearing type non-invasive instrument for quickly testing blood sugar

Abstract

A wearable non-invasive blood sugar fast tester relates to the detection technique, including a detecting instrument and a wearable component both of which are connected through a mechanical axis, wherein, the instrument can be worn on wrist, arm, ankle, etc., wherein, the detecting instrument includes an electric-acoustic-optic conversion unit, a signal preprocess unit, a central processing unit, an over-heat protection unit and a power module, these parts are in conventional electrical connection, and integrated within a shell; the electric-acoustic-optic conversion unit includes three laser diodes, a three-in-one fiber-optic and an ultrasonic sensors, three incident heads of the three-in-one optical fiber are, respectively, in coupling joint with the three laser diodes, and the emergent head is in fixed connection to the ultrasonic sensor, the three laser diodes are electrically connected to an analog switch, and the analogue switch is electrically connected to the central processing unit; the outer end of the ultrasonic sensor partly protrudes the housing, when in use , the part is close to the skin, for detecting the ultrasonic produced by blood in the skin. The invention hassimple structure, data accuracy, non-invasive, and capability of portable real-time detection.

Description

technical field [0001] The invention discloses a non-invasive blood glucose rapid detector for diabetic patients, belonging to the field of biological information detection, involving optics, acoustics, biomedicine, information science and various modern engineering technologies represented by electronic technology. Detection principle, to achieve non-invasive and rapid detection of blood sugar. Background technique [0002] With the significant decline of modern human labor intensity, changes in eating habits, and the intensification of population aging, the incidence of diabetes is rising rapidly. The impact of diabetes and its complications has become a serious public health problem that all countries in the world must face. one of the problems. Most of the blood glucose meters on the market are invasive and require a needle to get blood. The invasive detection method requires a needle for sampling, which not only brings great inconvenience and pain to the patient, but ...

Problems solved by technology

However, due to the many interfering factors in the human body and the lack of a single, specific absorption peak for blood sugar, the accuracy and sensitivity of optical methods are not ideal.
