METHOD AND APPARATUS FOR PENETRATING TISSUE

摘要

A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

1. A body fluid sampling system for use on a tissue site, the system comprising:
a controllable drive force generator; a plurality of penetrating members operatively coupled to said controllable drive force generator, said controllable drive force generator moving each of said members along a path out of a housing having a penetrating member exit into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site each of a penetrating member at least partially positioned adjacent to an analyte detecting member in a sample chamber, each sample chamber configured to receive body fluid from a wound in tissue created by a penetrating member, and each analyte detecting member configured to determine at least one analyte level using a body fluid sample of less than about 1 microliter; a support member with a surface that carries said penetrating members, said support member being movable to move each of said penetrating members to a launch position associated with said force generator; and said controllable drive force generator configured to provide a controllable velocity trajectory into the tissue and out of said tissue.
