Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring instrument control technology, specifically a control circuit for a glucose metabolism monitoring instrument. Background Technology
[0002] Glucose metabolism monitoring usually refers to continuous dynamic blood glucose monitoring technology, which is used to track changes in blood glucose levels in real time, and is especially suitable for the management of diabetic patients.
[0003] Current glucose metabolism testing is primarily invasive, involving methods such as drawing venous blood, obtaining finger prick blood, or minimally invasive continuous monitoring. Patients need to go to specialized medical institutions to complete these procedures, or they can prick their fingers themselves and use minimally invasive testing stickers. These procedures create wounds that require disinfection and care, which is very inconvenient.
[0004] Glucose metabolism testing needs to be dynamic and random to ensure that the values can effectively reflect the trend of a patient's glucose metabolism capacity. However, because invasive tests have relatively stringent testing conditions, it is difficult for patients to perform routine continuous glucose monitoring. Utility Model Content
