Abstract
An integrated body fluid sampling device is used to sample a body fluid from an incision in the skin of a body part. The device includes a lancet for forming the incision in the skin. A housing is coupled to the lancet. The housing defines at least in part a capillary channel with an opening. The capillary channel is sized to draw the body fluid from the incision via capillary action. An expression pad is coupled to the housing. The expression pad has opposing angled sides for compressing the backside of a body part where the incision is made. The lancet extends from the housing to form the incision. Fluid from the incision is drawn into the channel and is deposited on the test strip for analysis. A test strip is positioned along the capillary channel for analyzing the fluid.
