Abstract

The invention provides a wearable continuous blood glucose detection device and method; the device comprises a three-electrode microneedle module, a current-voltage conversion circuit and an MCU module, wherein a three-electrode microneedle penetrates into a corium layer to be in contact with tissue fluid but not in contact with blood; an original current signal is acquired; the acquired original current signal is amplified and filtered and then is processed by the current-voltage conversion circuit and the MCU module to obtain a processed current signal; the processed current signal is converted into the blood glucose concentration according to the relation between the current and the blood glucose concentration; and the blood glucose concentration is sent to an intelligent terminal through a Bluetooth signal. According to the wearable continuous blood glucose detection device and method provided by the invention, the cost is low; and accurate measurement and long-term monitoring of the blood glucose of a patient can be achieved.

Description

technical field [0001] The present invention relates to the technical field of blood glucose detection equipment, in particular to a wearable continuous blood glucose detection device and method. Background technique [0002] At present, the number of diabetic patients in the world continues to increase, and it has become the third largest killer of human health. Since diabetes is currently incurable, patients need long-term medication and intervention. Neglect of care can lead to a series of chronic complications in the eyes, kidneys, nerves, blood vessels, heart and other organs. Therefore, accurate measurement and long-term monitoring of blood glucose in patients are key issues in the diagnosis and treatment of diabetes. [0003] At present, the family fingertip blood glucose meter is the most widely used one, and it plays an important role in the early screening of diabetes and the management of blood sugar level of diabetic patients. However, the daily high-frequency ...
