Abstract:
1. A method, comprising: placing a sampling device against a tissue; creating an incision in the tissue with the sampling device; detecting with the sampling device that body fluid bled from the incision on the tissue is insufficient for analysis; and expressing the body fluid from the incision automatically with the sampling device in response to said detecting while the sampling device remains against the tissue; wherein the sampling device includes a housing with a cavity and a fluid detector configured to generate ultrasound in the cavity; wherein said detecting includes monitoring resonance of the ultrasound in the cavity of the housing; sensing an ultrasonic resonance that indicates the sampling device is placed against the tissue; and said creating the incision including firing a lancet into the tissue in response to said sensing the ultrasonic resonance that indicates the sampling device is placed against the tissue.
