Abstract:
1. A body fluid sampling device, comprising: a meter; a lancing device configured to create an incision in a surface of tissue, wherein the lancing device includes a lancet; a fluid detector configured to detect sufficiency of body fluid bled from the incision while on the surface of the tissue; an analysis device configured to analyze the body fluid once the fluid detector detects that the body fluid on the surface of the tissue is sufficient for analysis, wherein the analysis device includes a test strip; an integrated lancing test strip including the lancet attached to the test strip; the integrated lancing test strip being detachably coupled to the meter, the lancet and test strip of the integrated lancing test strip being configured to be removed together from the meter as a single unit; wherein the fluid detector includes one or more sensors disposed on the integrated lancing test strip to detect sufficiency of the body fluid bled from the incision while on the surface of the tissue; the meter including a housing in which the fluid detector is disposed, the housing defining a cavity with an opening where the incision is created; and wherein the fluid detector includes an ultrasonic detector configured to detect a change in resonance of the cavity in the housing as the body fluid from the incision fills the cavity.
