Methods and apparatus for expressing body fluid from an incision

A device for sampling body fluid comprising:

• a housing having an open end;
• a skin-lancing mechanism mounted in the housing for applying a skin-lancing medium against a skin surface to form an incision therein, and then removing the skin-lancing medium from the incision;
• a plurality of levers mounted to the housing at the open end thereof for movement relative to the housing, the plurality of levers pivotally attached thereto, wherein the levers cause the skin surface to form a bulge in response to a pressing on the housing;
• and
• a stimulator member mounted to the housing at the open end thereof for movement relative to the housing, the stimulator member extending about a longitudinal axis of the housing and having an end face adapted to engage the skin surface of the bulge and to stretch open the incision in response to a pressing of the end face against the skin surface.

A body fluid sampling device, comprising:

• a housing;
• an incision forming mechanism coupled to the housing to form an incision in skin;
• and
• means for squeezing body fluid from the incision after the incision is formed that is coupled to the housing.
