The invention relates to medicine and technology, and more particularly to non-invasively detecting a change in a person's blood glucose concentration, and can be used in the creation of sensors for non-invasively checking a person's blood glucose concentration. The aim of the invention is to improve the operational efficiency of a sensor of a device for non-invasively checking a person's blood glucose concentration by reducing the set-up and configuration time required. This aim is achieved in that the claimed sensor of a device for non-invasively checking a person's blood glucose concentration comprises a housing, a light emitter and a light receiver, the inner side of the housing having a rim disposed thereon which surrounds the light receiver and separates it from the light emitter, wherein the crest of said rim has alternating projections and depressions along its length, and during the set-up and operation of the sensor, the emitter and the receiver are pressed against the pulse point on the radial artery of the arm. The technical results of the invention include: increasing the adhesive force between the rim and a person's arm by increasing the contact area between said rim and the surface of the arm; reducing the energy spent on non-invasively checking a person's blood glucose concentration; and increasing heat transfer from the sensor via the crest of the rim to the person's arm by increasing the contact area between the rim and the arm.

BLOOD GLUCOSE MONITORING METHOD AND ELECTRONIC DEVICE

Resumen de: WO2025209494A1

The present application provides a blood glucose monitoring method. The method comprises: determining a first early warning duration according to first blood glucose data, wherein the first blood glucose data comprises blood glucose data within a first time period, and the first early warning duration is used for performing hypoglycemia early warning. The first early warning duration is related to blood glucose fluctuation indicated by the first blood glucose data. If the blood glucose indicated by the first blood glucose data fluctuates little and changes slowly, the first early warning duration can be longer. If the first blood glucose data input into a model indicates that the blood glucose of a user fluctuates greatly and changes rapidly in historical time, the first early warning duration can be shorter. By means of implementing the described method, the electronic device can adaptively adjust the first early warning duration according to the characteristics of the blood glucose variability of a user, thereby improving the accuracy of hypoglycemia early warning.
