Integrated lancing test strip
First Claim
1. A device for sampling a bodily fluid from an incision in skin, comprising:
- a lancet to form the incision in the skin;
a housing coupled to the lancet, the housing defining at least in part a capillary channel with an opening, the capillary channel being sized to draw the bodily fluid from the incision via capillary action; and
a flexible sheet extending from the housing proximal the opening of the capillary channel to draw the bodily fluid into the opening of the capillary channel.

Abstract
An integrated bodily fluid sampling device is used to sample a bodily fluid from an incision in skin. 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 bodily fluid from the incision via capillary action. A test strip is positioned along the capillary channel for analyzing the fluid. In one form, a flexible sheet extends from the housing proximal the opening of the capillary channel for drawing the bodily fluid into the opening of the capillary channel. In another form, the lancet is slidably received inside the channel. During lancing, 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.

38. An integrated bodily fluid sampling device for sampling a bodily fluid from an incision in skin, comprising:
-
a housing defining a capillary channel with an opening;
a flat lancet slidably received in the channel, the lancet having a lancet tip configured to form the incision in the skin, the lancet tip having a first position at which the lancet tip is positioned inside the housing and a second position at which the lancet tip extends from the opening of the channel to form the incision in the skin;
means for testing the bodily fluid positioned along the channel; and
wherein the capillary channel is sized to draw via capillary action the bodily fluid from the incision around the lancet and onto the means for testing the bodily fluid. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46)
