1. A lancing device comprising:
- a first housing having spaced apart proximal and distal ends disposed along a longitudinal axis;
a second housing disposed in the first housing and fixedly to the first housing;
a movable member disposed in the second housing and configured for movement along the longitudinal axis and in the first housing wherein the moveable member includes a plurality of arms extending away from the longitudinal axis towards the distal end;
a lancet coupled to the movable member;
a lancet depth adjustment member captured by both the first and second housings so that the lancet depth adjustment member is rotatable relative to both housings to provide for a plurality of stop surfaces to the movable member;
a first bias member located in the second housing to bias the moveable member in a direction towards the distal end;
a first actuator coupled to the moveable member so that the movable member is positioned proximate the proximal end in a primed-position;
a second actuator carried on a portion of the first actuator, the second actuator configured to allow the movable member to move from the primed-position proximate the distal end; and
a collect mounted on the plurality of arms for movement of the collect along the longitudinal axis on the plurality of arms from a first position of the collect in which the plurality of arms constrains the body of the lancet from movement and a second position of the collet in which the body of the lancet is free to move without constraint by the plurality of arms.

Abstract
Described and illustrated herein is an exemplary lancing device. The lancing device includes a first housing, second housing, movable member, lancet, and lancet depth adjustment member. The lancet depth adjustment member is captured by both the first and second housings so that the lancet depth adjustment member is rotatable relative to both housings to provide for a plurality of stop surfaces to the movable member. Other exemplary embodiments are also described.
