First Claim
1. A body fluid sampling device comprising:
- a housing defining a capillary channel with an opening configured to draw a body fluid via capillary action;
a lancet for forming an incision in a front side of a finger, the finger has a backside that is opposite the front side, the lancet being slidably disposed within the housing; and
a pad secured to the housing, the pad having opposing angled surfaces for compressing the backside of the finger to express the body fluid from the incision.

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.
