Non-invasive blood sugar instrument for closed-loop insulin injection

Abstract

The non-invasion blood sugar instrument for closed-loop insulin injection has built-in radio communication module, electrochemical electrode to extract hypoderis tissue fluid for non-invasion blood sugar detection, and insulin pump coupled through RF communication for insulin injection. The blood sugar instrument extracts hypoderis tissue fluid through the skin continuously and non-invasively with its constant sampling circuit combined with the electrochemical biosensor to, detects the glucose concentration in the tissue fluid and the blood sugar concentration by means of electrochemical process, transmits the blood sugar information and the time information through the RF communication module to the insulin pump for insulin injection and the closed-loop control of blood sugar level. The present invention can alleviate the pain of diabetics and raise his life quality greatly.

Description

technical field [0001] The invention relates to the field of biochemical detection, and is a non-invasive blood glucose meter for closed-loop insulin injection. Background technique [0002] Diabetes mellitus is a common endocrine and metabolic disease with a high incidence worldwide. Manual injection of insulin is currently a more effective treatment. However, the use of insulin pumps for quantitative injection of insulin requires that the blood glucose concentration in the patient's body must be measured in advance. Most of the blood glucose meters currently on the market are invasive, that is, blood is taken from the peripheral or vein, and then detected by electrochemical or optical methods. This kind of invasive blood sugar detection must be tested 7 times or more every day, which is cumbersome and increases the chances of patients infecting other diseases. Therefore, there is an urgent need for a non-invasive blood sugar detection device to continuously and non-invas...
