Abstract

The invention discloses a blood glucose sensor. The blood glucose sensor comprises an upper insulating layer, a separation layer, an enzyme reaction region, an electrode and a lower insulating layer in sequence from top to bottom, wherein a siphon channel is formed in one end of the separation layer; the electrode is partially exposed into the siphon channel and at least comprises a timing electrode and a temperature sensing electrode; and the temperature sensing electrode is partially exposed into the siphon channel. The invention further discloses a glucometer taking the blood glucose sensor as a blood glucose signal input source. The accuracy of an existing blood glucose test can be greatly improved.

Description

Technical field [0001] The invention relates to a human blood glucose detection tool, in particular to a blood glucose sensor and a blood glucose meter using the blood glucose sensor as a blood glucose signal input source. Background technique [0002] With the development of blood glucose detection technology, diabetic patients are becoming more and more aware of self-detection and blood glucose monitoring. They often self-test their blood glucose to understand their blood glucose control status and provide a reference for adjusting diet and treatment plans. However, blood glucose test results are affected by many factors, such as temperature. When the temperature is low, the enzyme activity is weakened, which makes the test result greatly deviate from the correct value. In order to measure accurate blood glucose values ​​at different temperatures, manufacturers have set up thermistors inside blood glucose meters to detect the temperature of the environment in which they are us...
