Abstract:
1. A body fluid sampling device, comprising: a housing configured to contact tissue; an integrated lancing-sampling device including a casing and a lancet for lancing an incision in the tissue slidably received in the casing, wherein the casing defines a sampling cavity for drawing body fluid from the incision, wherein the integrated lancing-sampling device is disposed inside the housing, wherein the casing of the integrated lancing-sampling device forms a reference surface upon which penetration depth of the lancet is based when the casing is pressed against the tissue, wherein the casing and the lancet of the lancing-sampling device are configured to be removed from the housing as a single disposable unit; and a positioner mechanism configured to retract the casing of the integrated lancing-sampling device from contact with the tissue after cutting the incision to a retracted position to promote flow of body fluid from the incision while the housing remains in contact with the tissue, the positioner mechanism being configured to subsequently move the integrated lancing-sampling device from the retracted position to a collection position where the body fluid is collected, wherein the casing of the integrated lancing-sampling device is positioned closer to the tissue at the collection position than at the retracted position.
