Wearable blood glucose meter

Abstract

The invention relates to a wearable blood glucose meter. The wearable blood glucose meter includes a main body unit which can be worn on the human body, wherein a detection unit, a digital / analog circuit conversion module, a display and a pressure stabilization unit are arranged on the main body unit, the detection unit includes a microneedle bed and a plurality of nano microneedles which are on the microneedle bed, and the nano microneedles are in contact with the human skin, and are stabbed into the human skin with minimal invasion so as to measure the biological signal of the blood glucoseconcentration of the human body; each microneedle includes a microneedle body and a silk fibroin layer, each microneedle body is wrapped by the corresponding silk fibroin layer, and each microneedle body is also provided with glucose oxidase; the glucose oxidase is exposed outside the silk fibroin layers, the digital / analog circuit conversion module is electrically connected to the detection unitand the display separately, and the blood glucose concentration biological signal which is collected by the detection unit is converted through the digital / analog circuit conversion module, and then is displayed on the display; and the pressure stabilization unit includes an elastic buffer element, and the detection unit is connected to the main body unit through the elastic buffer element.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wearable blood glucose meter. Background technique [0002] There are three main traditional blood sugar detection methods: extraction of venous blood for detection, rapid blood glucose meter blood glucose detection and blood glucose test paper colorimetric blood glucose detection. However, these blood measurement methods not only bring endless physical and mental torture to patients, but are also prone to infection and lead to more serious consequences. Therefore, it is an inevitable trend to develop a minimally invasive or even non-invasive blood glucose concentration measurement system to alleviate the pain of diabetic patients. [0003] Wearable devices, also known as wearable computing devices, generally refer to electronic communication devices that are embedded in clothing, or exist in the form of accessories and carry-on items. Such devices can be comfortably worn by us...
