Technical Field

The invention relates to the technical field of blood glucose measuring devices, in particular to a reusable applicator capable of preventing false touch.

Background

Diabetes mellitus is a chronic disease that is common to modern people. Diabetes is caused by an absolute increase in sugar content in blood due to an absolute deficiency or relative deficiency of insulin produced by pancreas, which is caused by various reasons such as obesity, stress, incorrect eating habits, congenital inheritance, etc., and the inability to correct the sugar balance in blood. Blood typically contains a concentration of glucose from which tissue cells extract energy. However, when glucose increases more than necessary, it cannot be stored in liver, muscle, fat cells, or the like properly and accumulated in blood, and therefore, the blood glucose of diabetics is maintained far higher than normal. As excess blood sugar is directly discharged through tissues to urinate, sugar absolutely required by each tissue of the body becomes insufficient, thereby causing abnormality of each tissue of the body.
