  • Patent number: 12678071
    Abstract: The present disclosure relates to a continuous blood glucose measurement device configured to prevent, in a state where a body attachment unit is inserted in and attached to a human body, an incision portion made by a guide needle from being formed to surround at least a part of a sensing area formed at a sensing member, whereby an incision portion is not formed around the sensing area so as to prevent the incision portion from causing a drop in a blood glucose measurement value and thus enable detection of an accurate blood glucose measurement value from the early stage of operation. Further, the guide needle has a shape not surrounding at least a part of the sensing area, so as to prevent, even without an additional device, the guide needle from forming an incision portion around the sensing area in a human body and thus enhance, by a simple structure, the accuracy of blood glucose measurement.
