Abstract:
1. A blood glucose sensor for measuring blood glucose in a blood sample withdrawn from a blood sample extraction site on a subject's body, comprising: a test strip; conductive contacts positioned on the test strip and defining a blood sample volume detection area; said test strip having a blood transport channel having a mouth at one end in fluid communication with the blood sample volume detection area; and a measurement site at an opposite end of the blood transport channel; the test strip being bent at a plurality of inflections and moved between a first inflection at which the blood sample volume detection area is opposite the blood sample extraction site and a second inflection at which the mouth of the blood transport channel is opposite the blood sample extraction site, wherein a blood sample bridging the contacts defining the blood sample volume detection area permits electrical communication between the contacts to detect a blood sample volume; and wherein the detected blood sample volume is sufficiently large that the blood sample moves through the blood transport channel to contact the measurement site when the mouth of the blood transport channel is moved to said blood sample extraction site.
