Patent Images
1. A body fluid sampling apparatus, comprising:
- a housing including a tissue interface surface;
a penetrating member;
a sampling chamber coupled to the penetrating member, the sampling chamber positioned to receive a body fluid from a tissue site in response to penetration of the tissue site by the penetrating member;
resources including a database that includes profiles of usersa pressure sensor positioned at the tissue interface surface for sensing and recording a pressure profile of a user; and
wherein a processor is provided that stores results and constructs the database for an individual user, the processor using the database to calculate profile traits of the user to optimize a user'"'"'s profile for subsequent lancing cycles.

Abstract
A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet and a processor coupled to the drive force generator capable of changing the direction and magnitude of force exerted on the lancet during the lancing cycle. The driver further includes a human interface on the housing providing at least one output for communicating with the patient.
