Abstract

A novel lancing device is presented which is compact, inflicts a minimal amount of discomfort to a user and is at least partially modular. The lancing device comprises a separable lancet, a lancet holder assembly and a hammer assembly which can be spring loaded. The lancing device of the present invention can be realized as a stand-alone type lancing device or integrated in to a more complex device such as an integrated testing or monitoring device including an integrated blood glucose monitor.
