1. A sampling device, comprising:
- a lancet configured to form an incision in skin;
an expression member having a band for receiving the lancet;
wherein the band is moveable between a relaxed position over the incision in skin and a contracted position over the incision;
a compression member configured to contact and traverse the expression member wherein the band compresses from the relaxed position to the contracted position to express bodily fluid from the incision in skin;
a housing configured to contact the skin near the incision; and
wherein at least a portion of the expression member is resilient in order to return to the relaxed position.

Abstract
A body fluid sampling device includes an expression member placed around an incision in the skin of a user, a compression member to contact and traverse the expression member, and a housing configured to contact the skin near the incision. The expression member is configured to repeatedly move from a relaxed position over the incision to a contracted position over the incision. The expression member is at least partially resilient in order to repeatedly squeeze and/or compress the skin around the incision.
